The present invention relates to systems and methods for operation of elevators or other user access gateways.
To facilitate further description of the embodiments, the following drawings and descriptions, which should not be considered limiting in any way, are provided. The drawings do not illustrate every embodiment of the present invention. With reference to the accompanying drawings, like elements are numbered alike.
The present invention addresses several needs relating to, as well as new and useful improvements in, elevator and other gateway access operations. Elevator systems are used throughout the world and may embody control systems ranging from very basic to highly sophisticated. Expanding digital controls and digital interfaces increasingly provide many advantages to elevator users as well as elevator owners (e.g., owners of buildings having one or more elevator systems). However, many limitations inherently exist in elevator control systems installed around the world—most of which include only very basic control systems. Some significant limitations are that many installed elevator systems are limited to the technical bounds of the original control systems of the elevator and/or limited by the high costs of upgrades to proprietary control systems of the original elevator control system manufacturer.
Accordingly, there is a need for universally applicable elevator control systems digital retrofits or upgrades that can be easily applied to a wide range of original equipment manufacturer (OEM) sourced elevator control systems and Non OEM sourced elevator control systems without entailing too high a cost or complexity in equipment, installation and operation while yet providing a robust platform for yet future enhancements and sophistication in the control systems. Further, there is a need for digital control packages and components for new build elevators according to certain embodiments of the present invention. Further, there is a need for an independent elevator system health monitoring and reporting system.
Aspects of certain embodiments of the present invention provide such a “universal” independent elevator digital control system that can be inexpensively supplied and easily installed on virtually all existing elevator systems without compromising the underlying mechanical and safety operations of the elevator system. Aspects of the present invention may also be applied to new elevator installations or build-outs as well as to other digital gateway control systems.
Additionally, aspects of certain embodiments of the present invention provide that the universal independent control system, once installed, can be configured to operate in conjunction with elevator users' mobile phones or other electronic devices such that the elevator user may, via the user's mobile phone (or other electronic device), call an elevator and select a destination floor and be conveyed by the elevator without having to physically touch any input components of the elevator (apart from actually entering and riding the elevator). In the same fashion, a user may, via mobile phone or other electronic device, communicate other commands or instructions to the elevator system such as “close door”, “hold door open”, “stop elevator travel”, signal an “alarm”, and/or other typical elevator commands or instructions. Further, data, messages, instructions and other information from the universal control system can be communicated or supplied to the user's mobile phone or other electronic device where it may be displayed, prompt user input, and/or issue audio signals or speech to facilitate the use of the present invention by people with disabilities, and/or otherwise utilized on the mobile phone or other electronic device. More discussion of the touchless control aspects of the universal control system will be presented below.
Some or all of the components of the system, can, in certain embodiments employ smart technology such as to learn and automatically select user preferences (such as floor destination) when the user's mobile phone is detected by the system.

The Illustrative Embodiment of
As stated above,
As also shown in
Further, as shown in the embodiment of
In some embodiments of the control system 10, an alternate component/embodiment to the UICD 30 (or 130) may be utilized. Examples of aspects of certain embodiments of these components are shown in
Further, in some embodiments the UICD 30 or UID 31 functionality can be built into other components—such as HUFDs 24 (and/or ICUDs 25 and/or other components of system 10 such as an independent control device)—so that the other components (or components of the system 10) can communicate directly with existing elevator machinery 150 or elevator controller 20.
In other embodiments, data from the IUPS 23 may be communicated directly or indirectly to one or more HUFDs 24 and/or the ICUD 25 and/or the UICD 30 and/or other components of the system 10 (see, for example the schematics from
As also shown in
In some embodiments, the system 10 may comprise an independent control component in functional communication with other components of the system 10. The independent control component may be configured to process received signals corresponding to elevator passenger call inputs, passenger floor destination inputs, and elevator vertical position data and generate an elevator car travel itinerary based on the processed signals. The independent control component may generate command signals for transmission to the elevator controller to cause the elevator controller to provide elevator car service conforming to the generated elevator car travel itinerary. The independent control component may further dispatch the generated command signals, or signals representing the same, such that they may be communicated to the elevator controller. In some embodiments, the UICD 30 (or 130) may comprise the independent control component. In some embodiments, one or more HUFD 24 (or 124) may comprise the independent control component. In some embodiments, the ICUD 25 (or 125) may comprise the independent control component. In some embodiments, the independent control component may be comprised as a component other than an HUFD 24, UICD 30, or ICUD 25.
In some embodiments, such as an instance wherein only one passenger presents to the system 10, the itinerary may be a straightforward response to the passenger's call for service. For example, if the elevator car is at floor 6 and with no passengers on board and in a stationary state and a passenger submits a call for service at the first floor, the generated itinerary may be a simple command to dispatch the elevator to the first floor so as to pick up the passenger. In such instances the itinerary may comprise the simple dispatch to floor 1 and, so, the itinerary may be spoken of as being “identified” (from the service call) and then transmitted to the elevator controller. However, even in this instance, the itinerary may become more complicated and, so, may be spoken of as being “generated” by the control component. For example, if during the travel of the elevator car to the first floor service calls for descending service are input from separate floors (for example floor 4 and floor 3), the control component may generate an itinerary that adds stops at both floor 4 and floor 3 and transmit appropriate itinerary commands to the elevator controller so that the elevator stops at floors 4 and 3 to pick up the descending passengers at those floors. It can be seen in this fashion that the control component may receive and process inputs from service calls and target floor destinations and also process data from an elevator vertical position sensing system to generate travel itineraries to meet the passenger requests and while yet complying with order of service command protocols that may have been provided to the control component. In addition, in the instance of a plurality of elevators at a single facility, one or more control components may singly or cooperatively generate separate itineraries for each of the elevators to provide optimized service to the passengers presenting to the system. Further, itineraries may be generated that take into account priority of passengers or priority of floors serviced or other rules or priorities as may be defined and provided to the elevator controller from time to time.
In some embodiments, the system may comprise an independent interface component configured to groom dispatched command signals from the independent control component such that the groomed command signals mimic signals received by the elevator controller from the first floor devices and the first car control input panel. In some embodiments, the system 10 is configured such that the groomed dispatched command signals from the independent interface component may be communicated to the elevator controller. In some embodiments the independent interface component may comprise the UID 31 (or 131) and may comprise a separate device in the system 10 or may comprise functionality otherwise embodied in other components of the system 10, such as a HUFD 24, the ICUD 25, and/or the UICD 30.
The Illustrative Embodiments of
The embodiments shown in
By way of example, in some embodiments the analog outputs of analog interface board 36 may be connected to relays (not shown) of the elevator controller 20. By way of explanation and background, in some embodiments the elevator controller 20 (absent the present invention) may control movement of the elevator car 12 to a destination floor by outputting an analog signal to the connected relay assigned to the destination floor, with a separate relay dedicated to each floor served by the elevator. In some embodiments, when the present digital control system 10 is connected to such a set of relays, a separate conductive connection is made from the analog interface board 36 to each of the separate relays. Thus, the analog output from analog interface board 36 corresponding (for example) to floor 3 may be connected by an electrical conductor to the elevator controller 20 relay assigned to floor 3. In the same fashion, each of the other analog outputs from analog interface board 36 may be connected by an electrical conductor to the elevator relay corresponding to the appropriate analog output. In further explanation, when such an embodiment of the present control system 10 is connected to the appropriate relays, the control system 10 can send analog signals, duplicative of (or mimicking) those otherwise sent to the relay by the elevator controller 20, to direct the elevator car 12 to any of the floors assigned to the relays. In some embodiments, there will be no difference in the analog signal received by the relays between those originating from the original controller 20 or the analog interface board 36 of the present invention. Accordingly, the addition of the universal independent digital control system 10 of certain embodiments of the present invention can simply “lay over” the existing signals input to the elevator controller 20 and do so without altering any of the designed safety or operational tasks programmed into and followed by the elevator controller 20 once it has received signals from either call buttons or elevator control panels (or digital system 10). It should also be noted that in some embodiments, a HUFD 24 on a particular floor can be operatively connected to the call button circuit of the existing call button on the particular floor. One or more signals, such as an analog signal, from the HUFD 24 to the call button circuit can then activate the call button circuit such that the call button circuit transmits its “normal” call signal to the elevator controller 20 via the call button's existing communications pathway to the controller 20. In this way, speaking generally, the elevator controller receives a standard signal via its standard communications pathway from the call button and can respond appropriately, but the call button circuit was actually activated by the signal(s) from the HUFD 24 on that particular floor. By these methods, the HUFD's 24 can effectively communicate with, and direct, the controller 20 via the existing communications system extending between the respective call buttons and the controller 20. In such instances the HUFD 24 can provide a signal to the call button circuit mimicking the call button normal signal or otherwise activate the call button circuit so that a “call” signal is sent from the particular call button to the controller 20. In similar fashion, an ICUD 25 can be operatively connected with the several buttons or button circuits in the elevator car control panel. By activating the appropriate button circuit of the elevator control panel, instructions from the system 10 (or more directly from the ICUD 25) can be transmitted from the system 10 to the controller 20 via the elevator car control panel circuits and their respective signaling paths and signal inputs to the controller 20.
Also, in some embodiments of the present invention, the electrically conductive connection from the outputs of the analog interface board 36 to the respective relays also convey an electrical signal back to the analog interface board 36 when the relays are activated such as by one or more analog outputs from the elevator controller 20 to the respective relays. In this fashion, in some embodiments, the digital control system 10 is informed of elevator controller 20 activation of particular relays (and the controller's 20 command to send the elevator to a particular floor).
In somewhat similar fashion the serial interface board 38 may be connected to appropriate connections in an elevator controller utilizing digital input/outputs. The digital control system 10 can then send and receive digital signals either directing movement of the elevator car 12 or tracking actions otherwise directed by the controller 20. Further, in some embodiments other communication systems or interfaces may be used between the existing elevator system (including, in some instances, controller 20)
The data received at either the analog interface board 36 and/or serial interface board 38 from the elevator controller 20 and/or the controller relays can be processed and/or communicated to other components of the digital control system 10.
Additionally, signals from the UICD 30 may be transmitted to one or more of the HUFD 24 (and also to the ICUD 25) such as for control purposes as well as to support audio or visual output from the HUFD 24 (or ICUD 25), including output such as shown in

It can be seen that, in some embodiments, the universal digital control system 10 can be economically retrofitted into an existing elevator system. In such a retrofit, no changes need to be made to the existing systems of the elevator system except connection of the UICD 30 (or UID 30) to the elevator controller 20. It can be seen, then, that the universal digital control system 10, in certain embodiments, is fundamentally self-contained. It may collect elevator car 12 location and travel direction from its own vertical position sensor components IUPS 23 (or alternately separate IUPS components 26 and 28) (or other IUPS 23 sensing systems/units such as HUFD 24 and ICUD 25 relative position) and provides data communications between every HUFD 24 and the UICD 30 (or UID 30) by one wireline connection 32 that is easily disposed in the hoistway 14. As noted above, the HUFDs 24 may also communicate wirelessly with the ICUD 25 in the elevator car 12. Further, UICD 30 (or UID 30) may also communicate wirelessly directly with the ICUD 25.) Alternatively, communications between HUFDs 24 as well the ICUD 25 and the UICD 30 (or UID 30) may be accomplished by wireless communications. The elevator controller 20 after retrofit of the elevator system with a universal digital control system 10 of certain embodiments, continues to operate with all its preset operational and safety protocols unaffected by the addition of the universal digital control system 10 except that UICD 30 (or UID 31) provides “piggy-back” or “lay-over” data input to the elevator controller 20. But, in many embodiments, the data input provided by the IUCD 30 (or UID 31) to the elevator controller 20 is identical to (or mimics) the data input otherwise provided to the elevator control 20 by the pre-retrofit (as well as post-retrofit) elevator call buttons on each floor and the target or destination data signal sent to the elevator control 20 by the pre-retrofit (as well as post-retrofit) from the user input control panel in the elevator car 12. Thus, the universal digital control system 10 of particular embodiments can be “universally” applied to virtually any pre-existing elevator system in a very non-complicated fashion since the digital control system 10 does not interject into any of the proprietary controls or safeguards of the original elevator system. As also discussed herein, the system 10 can be configured to connect directly into the call button circuits already existing at each floor and/or into the button circuits of the elevator car control panel. In this fashion, the system 10 carries out all the designed control, management, and tracking of the system 10 while directly transmitting system 10 command signals to the controller 20 via the existing communication channels of the floor call buttons and/or elevator car control panel. Further, in some embodiments, the universal digital control system 10 can be locally managed and does not require WIFI or cloud internet exchanges to place an elevator call.
In some embodiments ICUD 25 (and/or ICUD 125, e.g., (from
The digital control system 10 and its components can be provided with “smart” digital capabilities to facilitate sophisticated and evolving digital services by the system. The system 10 can provide smart features to the owner and user of the elevator system, thus easily upgrading a previously “dumb” or unsophisticated elevator system into an intelligent or “smart” elevator system. As an example of a smart functionality, the system 10 (or components thereof such as a HUFD 24 or ICUD 25) can recognize the mobile phone of repeat users of the system 10 and predict that a particular user (based on that previous user's use of the elevator system) will most likely wish to repeat a particular destination floor selection. Accordingly, when the particular user's presence is detected approaching a HUFD 24 or ICUD 25 the system 10 can anticipate the user's most likely floor destination objective, call an elevator to provide the anticipated elevator service, and notify the user's mobile device that a particular elevator is available (or arriving at with an identified estimated time of arrival) for the user's elevator travel. The user may enter the identified elevator car 12 and the system 10 can execute the appropriate elevator controls to deliver the user to his/her target destination floor without any action by the user. The system 10 can detect the user's entry and presence in the identified elevator car 12 and then proceed to close the door 18 and transport the user to the destination floor. In some embodiments, the system 10 can await a confirmation by the user of the “smart” identified target floor suggested by the system 10 prior to transporting the user. Since, in many embodiments, the application 33 can be universally recognized and used by any elevator system in which the universal control system 10 has been installed, a user may approach any such system 10 (regardless of whether the user has previously used the particular system 10), have the user's mobile device recognized via the system's interfaces and communications with the user's application 33 and enable the user to utilize his/her mobile device 8 to control the previously unused (by that particular user) elevator system. Further, since the control system 10 may be smart enabled, after one or more uses by the particular user the control system 10 may proceed to suggest an anticipated elevator destination for the user, and possibly after one or more confirmations by the user, automatically proceed to deliver the user to the anticipated destination floor without further prompting or input by the user. In embodiments where security measures are desired for user travel to particular floors, registration of the user and his/her mobile device may be input into the control system 10 prior to the user's use of the system 10 to access the secured floor(s). Further, tenants, residents or management of secured floors can easily send “pass authorization” to anticipated visitors of the secured floors mobile device 8 via text, email, the global application service or other techniques so that the application on the anticipated visitor's mobile device 8 can accept the sent and received “pass authorization” and communicate this “pass authorization” to the control system 10 when the authorized user approaches a HUFD of the particular system 10. Thus, secured access to particular floors can be controlled easily by the secured floor party without the intervention of resident security guards or other intervention. Further, capabilities of the system 10, such as for example ICUD) can confirm that the authorized user (and no one else) has entered a particular elevator car prior to the elevator car 12 being dispatched to the secured floor. In some embodiments, the application may include interfaces with scheduling or appointment software or such so that “pass authorization” is automatically conveyed to scheduled appointment visitor's mobile devices 8 in order to facilitate their automatic authorization to secured floors. Further the application 33 can notify the authorizing party of the arrival of the authorized user at the particular building or elevator proximity and the target arrival time of the visitor to the secured floor. Additionally, such notifications can be provided by the application 33 for the arrival of users to non-secured floors.
In some embodiments, the digital control system 10 may be configured to generate one or more alarms or other system actions/decisions when the presence of an unauthorized person is sensed in certain areas such as the elevator car, elevator lobby and/or other areas of a building or structure. In some embodiments, the digital control system 10 may be configured to implement certain actions at a detected security breach, or in instances such as when the elevator car may stop in the hoistway with passengers inside, or if suspicious behavior is detected in the proximity of the arrival landing near the elevator door of a floor. Further, certain embodiments may also be configured to sense or detect properly mask wearing, body temperature, biometric data recognition (i.e. face recognition, etc.), presence or proximity detection or recognition, social distancing, limited mobility of passengers or prospective passengers and to take predetermined action in such sensed or detected instances. The provision of such flexibly adapted and programmed control systems for the many existing and, comparatively, very “bare boned” control systems of older elevator systems, presents advantages with minimal retrofit or installation costs or difficulties, very low component cost, very high sophistication, and a platform that can be readily updated.
In some embodiments, all or portions of the smart functionality of the system may be embodied in each HUFD 24, only one HUFD 24, in the UICD 30, in the ICUD 25 or any combination thereof. Some embodiments provide universal processor enabled individual components that can be assembled into a complete control system 10 and/or assembled in plug and play fashion, as well as variations in processor implementations selected in setup of the components in the system. In other embodiments, the control system 10 may comprise only a limited number of smart processor units and linked components of the system 10 communicate with and utilize the limited number of smart processors to achieve overall satisfactory system functionality at lower component total cost.
In some embodiments, the digital control system 10 can thus upgrade a previously “dumb” elevator system into a “smart” elevator system that can recognize passengers mobile or other devices when the user or passenger approaches a building. The system 10 can then reserve elevator service through an application downloaded onto the user's mobile device 8 (or other electronic device). For passengers requiring security access services, the control system 10, in some embodiments, can confirm the passenger's permission for access and provide elevator service as the passenger approaches proximate the HUFD 24 or enter the car ICUD 25. In some embodiments, the control system 10 can communicate to the user's mobile device 8 the availability of the elevator service and the floor location and direction of travel of the elevator (as well as other information) being provided for the user service. Further, the control system 10 in some embodiments facilitates a completely touch-free user experience such that the elevator user may entirely call and command an elevator simply by using the user's mobile phone 8. Accordingly, a very simple elevator can inexpensively, quickly and efficiently be provided with an advanced digital touch free control system that upgrades the elevator to the most advanced digital experience—and that experience, one that can be continually updated by the simple step of updating the software and/or certain firmware of the control system 10.
The control system 10, due to its independent standalone design (being independent from the pre-retrofit elevator control system), can also show and or detect anomalies happening to the elevator systems operation thus providing a smart series of reports or alerts to the various building or elevator stakeholders depending on the type of the application to the control system (which may be based on various stakeholder configuration choices). In some aspects, due to its independent standalone design, the control system 10 can serve as an “external” or “independent” supervisor. Thus, the control system 10 may be, in some embodiments, seen as a doctor constantly monitoring the health of the elevator system to which it has been installed. Since the control system 10 may have its own IUPS 23, acceleration, vibration and noise sensors, extract controller 20 signals and information, and data analysis capabilities it can constantly accurately ascertain the performance as well as anticipate potential issues in the elevator system that may not otherwise be detected in the elevator system without specialists are inspecting the system.
The control system 10 increases over time the reliability of previously dumb elevator operation inasmuch as it may have no moving parts, is digital, and transforms the previously dumb operation of the elevator system into a smart elevator digital system. The control system 10 works as a parallel reliable system, actually supervising the dumb elevator—transforming the entire user experience with the elevator service into a preferred smart digitally enabled elevator experience. The control system 10 can be economically designed and produced to be universally applicable to the various designs of original equipment elevator services. Since the control system 10 is modular and intelligent it can support upgrades with add-on functionalities and features that provide value to stakeholders as additional services may be desired and/or digital capabilities develop.
The control system 10 can also provide independent performance analysis of the elevator system such as the number of runs and duration in every direction and floor destination, number of doors/locks opening and closing and the stopping accuracy at each floor, noise inside the car or due to the door operation as well car and doors vibrations. Further, with digital sensors in the machine room or other elevator equipment spaces, the control system 10 can log and confirm the presence of maintenance mechanics in the elevator machine room or other elevator equipment spaces. Additionally, the control system 10 can log passenger information including information such as direction and position of elevators. The system 10 can provide time savings such as by booking arrival of elevators in advance to the point of use and information such as ETA to dispatched floor and ETA to arrival to destination floor. Each or various of the HUFDs or ICUDs may incorporate cameras, motion sensors, temperature sensors, proximity sensors, light sensors, loudspeakers, micro and associated digital processors and software to facilitate many intelligent or smart systems controls or features. For example, the system 10 can provide security advantages such as aggressive behavior recognition (and, when recognized, trigger locking or opening doors as may be desired), passenger biometric data recognition (i.e. face recognition, etc.), surveillance camera operations, and client's phone number recognition. The control system 10 can also be provided with health and safety features including detection, recording and/or alerting of predetermined body temperature, predetermined social distancing, mass detection and air sanitation conditions as well as actuate air sanitation functions. The control system 10 can also provide usage safety such as activation of light in the elevator car 12 and other safety features such as elevator door 18 closing delay based on user conditions (such as a detected wheelchair, child stroller, or slow-moving person, stretcher, boxes are on the landing and/or are removed).
The digital control system 10, in some embodiments, may be designed in order to avoid any connection (apart from, in some embodiments, attachment of a ICUD 25 to the interior of the elevator car 12) to the elevator car 12 and therefore eliminates any need to run wires through the flexible cables 31 typically used to communicate with the elevator car 12 (in typical pre-existing elevator systems).
Since the control system 10 may include its own independent battery backup systems and its own elevator location sensing system it can serve to reliably provide accurate elevator car 12 actual location in the event of building power loss or emergency stoppage of the elevator. Accordingly emergency or other personnel approaching the elevator system can readily identify (such as from display of HUFD 24 or via application 33 communications to personnel mobile devices 8) the precise location of a stopped elevator car 12 without entering the hoistway or opening doors 18. In the same way the users are informed via smartphone or other devices if the elevator is out of service and where the cab is stopped.
The universal control system 10 can provide an equivalent to replacing the existing tactile buttons of the pre-retrofit elevator system, can provide intelligent building management systems, can provide software and devices to control access to buildings and can serve to provide an independent supervision of elevator operations.
In some embodiments the control system 10 has only a single point of attachment or connection to the pre-retrofit elevator system. That single point of connection may comprise the data communications between the UICD 30 (or UID 31) and the elevator controller 20. In some embodiments the control system 10 has one or more points of attachment or connection to the pre-retrofit elevator system. That alternative single point of connection or connection between the UICD 30 (or UID 31) and the ICUD 25 may be through the pre-existing car operating panel installed inside the elevator car or the HFUDs 24 and the pre-existing hall buttons installed at the landings or in other embodiments the ICUC 25 can be connected to the pre-existing car operating panel and the HUFD's 24 can be connected to the pre-existing hall buttons. In some embodiments the control system may have only a single point of attachment, connection or communication with the pre-retrofit elevator system—that single point may be an input to the elevator controller 20—either directly or indirectly.
In some embodiments, the control system 10 can be applied with appropriate interface to existing elevator controls to multi-elevator buildings or installations.
In some embodiments, the control system may not include the use of ICUDs 25 (See,
In embodiments such as of
In some embodiments one or more HUFDs 124 may embody a bulk of the intelligence of the system 10. One or more HUFD 124 may include UICD 130 or UID 131 and data may flow between that one or more HUFD 124 and elevator machinery 150 and/or elevator controller 20 via communications path 146 or other communications paths or systems. Drawings show both wired and wireless communication solutions.
Importantly, in some embodiments the control system 10 can leverage existing systems of the existing elevator. For example, in some embodiments, the control system 10 can collect information from the existing elevator vertical position system rather than utilizing an independent universal position system 23 or 123 and use the collected vertical position information in operation of the control system 10.
The control system in some embodiments may comprise a unique Independent Universal System 10 comprised of a HUFD 24 at each floor or only at some (or one) floor of those floors serviced by a particular elevator system. Some embodiments may comprise HUFDs 24 with embedded information permitting display of the elevator position and direction information independently from the elevator control system. In some embodiments, one or more HUFDs 24 may comprise a reader transmitter that connects with the user smartphone or similar devices. In some embodiments, a ICUD 25 may be connected wirelessly with one or more HUFDs 24 and may have a reader transmitter that connects with the user smartphone or similar devices. In some embodiments, the control system may comprise an IUPS 23 that enables a HUFD 24 to detect the position of the elevator car independent and free from any interference with the pre-existing or traditional elevator system. In some embodiments, the control system may comprise an IUPS 23 that enables a ICUD 25 to detect the position of the elevator car independent from and free any interference with the pre-existing or traditional elevator system. In some embodiments, the control system 10 may comprise only one electrical interface with the elevator system and that electrical interface may be from the UICD 30 or UID 31 to the elevator controller 20. In some embodiments, the control system 10 may enable command and supervisory function by the control system 10 over the otherwise existing elevator machinery. In some embodiments, a smartphone application in a mobile device 8 may receive data from the control system 10 and the data received is sourced only from the control system 10 without reference to data from the otherwise existing elevator control systems. In some embodiments, a smartphone application in a mobile device 8 may send data to the control system 10 to control operations of the elevator system via the control system 10 without accessing manual elevator call buttons or elevator internal control panel buttons.
The control system 10 may, in some embodiments, be modular with the various components readily identifying other installed control system 10 components (such as HUFDs 24, ICUDs 25, UICD 30 and other components) and in some embodiments providing essentially a plug and play variety of components. Further, various embodiments may provide different levels of sophistication in the capabilities and processing of the several components of the control system 10. Such modular embodiments, particularly, with varying levels of processing sophistication in various system components allows for a readily connected variety of components with component cost factors matched to the needed processing sophistication capabilities of the particular components of the system assembled to be installed.
For example, in some embodiments the HUFDs 24 serve relatively simple functionality of communicating with user mobile phones 8, ICUD 25 and the UICD 30, while the UICD 30 carries out tracking the elevator car 12 location data from IUPS 23, communication to elevator controller 20, formulation of signals back to HUFDs 24 and ICUD 25, and tracking and logging of elevator performance data.
For example, in some embodiments the UID 131 functions primarily as only an interface device communicating with the existing elevator machinery 150 while the intelligence (or control component) of the system 10 is embodied in one or more HUFDs 124 (with the one or more HUFDs 124 carrying out tracking the elevator car 12 location data from IUPS 123, communicating to the UID 131, communicating with the ICUD 125, communicating with other HUFDs 124, and tracking and logging elevator performance data). The logging can be everywhere included the smartphone of the users and info are downloaded when 8 is connected to the WI FI.
For example, in some embodiments each HUFD 24 may comprise relatively sophisticated processing capabilities providing processing intensive capabilities such as passenger biometric data recognition (i.e. face recognition, etc.) at each floor location, in other embodiments the ICUD 25 can perform the same relatively sophisticated processing capabilities providing processing intensive capabilities such passenger biometric data recognition (i.e. face recognition, etc.). In some of these embodiments the UID 131 may be relatively non-sophisticated and system 10 principal controls, control component functions, and data tracking and logging may be carried out by one or more of the relatively sophisticated HUFDs 24 (or ICUDs 25).
For example, in some embodiments one HUFD 24 (and/or ICUD 25) may comprise relatively sophisticated processing capabilities providing processing intensive capabilities such passenger biometric data recognition (i.e. face recognition, etc.) at one floor such as the main or ground floor. The additional HUFDs 24 on other floors may be relatively less sophisticated with the one HUFD 24 on the main or ground floor conducting principle system 10 controls, inter-component communications and data tracking and logging.
In some embodiments, the present invention may comprise a system wherein a device not attached to the elevator car controls operations of the system. For example, in some embodiments a device neither attached to a floor or the elevator car controls operation of the system. For example, in some embodiments the device which controls operations of the system may be associated with a vertical position sensing system or may be positioned elsewhere in relation to the elevator system.
In some embodiments, the communications from the elevator passenger (whether a service call from an individual floor or a target floor destination input—or other passenger command (e.g., stop, hold doors, close doors, etc.)) may be received directly at the ICUD 25 without being first received at a HUFD 24. In some such embodiments, inclusion of separate HUFD's 24 may not be needed. In some embodiments of this fashion, the system 10 may comprise an ICUD 25 comprising a control component in communication with a vertical position sensing system, the ICUD 25 configured to receive passenger service call requests, target floor destination inputs (and, in some instances, other passenger inputs), the ICUD 25 further in functional communication with the elevator controller and directing elevator car travel and service with the elevator controller responding to directions from the ICUD 25 and yet maintaining control over travel and safety operations of the elevator.
While the particulars of certain embodiments have been described in this specification, it should be understood that in certain embodiments any or all of the first or second communications systems may comprise wireless communications.
It should be understood that certain embodiments of the present invention may comprise an independent elevator control system to be used or installed in an elevator system wherein the first elevator system does not comprise all the components of a first elevator system as otherwise described herein. Further, it should be understood that certain embodiments of the present invention may comprise all or some of the components or aspect of the presently described independent elevator control system applied to a new build or rebuild elevator system wherein the components of the presently described independent elevator system comprise the only floor devices and/or the only elevator device and/or the only vertical position sensor system in the new build. By way of illustration, in an exemplary new build elevator system, the principal floor devices may comprise HUFD's, and/or the principal elevator car control panel device may comprise an ICUD, and the principal vertical position sensor system may comprise an IUPS. In some such embodiments, the new build elevator system may be configured without the use of floor devices other than the HUFD's, and/or the elevator control panel device may comprise substantially only an ICUD, and/or the new build elevator system may rely principally on the IUPS rather than a different system for vertical position sensing. Similarly, in a rebuild scenario, existing floor devices, elevator control panel components, and/or vertical positioning components may be disabled or removed and the rebuilt elevator system may be functionally configured using one or more of the HUFD's, ICUD and/or IUPS. In addition and in some instances as alternative embodiments various of the HUFD's, ICUD and/or IUPS may be substituted for first system (or otherwise existing) floor device, elevator control panels and/or vertical positioning system which substituted first system components may be disabled, removed, replaced or left intact while one or more of the HUFD's, ICUD, and/or IUPS components or functionality may be inserted into the existing elevator system.
In some embodiments a EUDA type controller functionality can be embodied in a new equipment elevator controller, termed in this case a EUDA enabled controller. In some embodiments a EUDA enabled controller can be installed in conjunction with a new elevator system and can be in functional communication with EUDA floor devices and EUDA elevator car device(s) via wireless connections and without physical wiring between the EUDA floor devices, the EUDA elevator car device(s) and the EUDA enabled controller. The EUDA enabled components can then control the elevator system while also providing all the other EUDA enabled features described in this application.
In some embodiments a EUDA enabled controller may be installed in an existing elevator system and communicate wirelessly with EUDA floor devices and EUDA car device(s) that, similarly, have been installed at the existing elevator system. The EUDA enabled components can then control the elevator system while also providing all the other EUDA enabled features described in this application.
In some embodiments, the EUDA system may deduce the number of passengers in a particular elevator car. The number of estimated passengers in the elevator car may then be used to estimate the weight of passengers or loading in the elevator car. This estimated weight can then be used by the EUDA system to guard for and/or implement safety features such as alarming for a weight overload situation and possibly taking appropriate action (such as not allowing the elevator doors to close or not allowing the elevator car to travel), or providing directions that some passengers should exit the car for weight or safety reasons, or other appropriate action. In some embodiments, the EUDA system may detect the presence of cargo, packages or other non-living objects in the elevator car and generate an estimated weight for such objects in the EUDA calculations for weight loading of the elevator car.
In some embodiments the EUDA system may use the number of mobile phones detected in the elevator car to estimate the number of passengers in the elevator car. In some embodiments the EUDA system may use sensors, such as cameras, heat sensors, or other sensors, to estimate the number of passengers in the elevator car. From the estimated number of elevator passengers in the elevator car, the EUDA system can calculate an estimated weight of the estimated total number of passengers (such as by using one or more preset weight values associated with each type of passenger detected in the elevator car).
In some embodiments the EUDA system or a health device/system as described herein may use the deduced number of passengers and/or estimated weight loading in the elevator car and accumulate the deduced loading data in operational databases for service, safety, maintenance and/or other reasons. Additionally, data relating to the accumulated weight loading and elevator weight load carried by the elevator may be communicated to systems outside the immediate elevator system.
In some embodiments the EUDA system can function to cause the elevator car, notwithstanding possible contrary operational protocols of the elevator system, to skip floors (i.e, not stop and open doors at one or more skipped floors) in circumstances wherein the EUDA system has determined that the elevator car is fully loaded (such as by reaching an assigned estimated weight of passengers or cargo) and that there are not passengers in the elevator car targeting to disembark the car at the skipped floor(s).
In some embodiments the EUDA system may optimize traffic patterns of the elevator car(s) based on the EUDA's knowledge of the location and destination requests of elevator users and at the floors and the passengers in the elevator car(s). In some embodiments, the EUDA system may further recognize the number of people waiting on one or more floors for elevator service and utilize this recognized number in the EUDA calculations to optimize elevator travel and traffic operations.
In some embodiments the EUDA system may serve to detect and provide indication and/or notification to a call center for service or rescue operations of an “Out of Service” or “Trapped Passenger” condition.
In some embodiments the EUDA system can recognize passengers (e.g., via phone ID, face recognition, or other) and ascertain whether the recognized passenger is boarding the appropriate elevator car targeted for the destination floor of that passenger (including, such as in a multi-car elevator system). Further, in some embodiments a EUDA system can identify and alert passengers if a passenger is disembarking the elevator car on an incorrect floor (as ascertained by the target floor requested by the particular passenger).
In some embodiments the EUDA system can enable recognition of voice commands such as to keep open or to close landing doors such as if there is a user whose hands are otherwise occupied, such as by holding parcels, a child, the leash of an animal, pushing a stroller, a wheel chair, or such. Once enabled, the EUDA can use recognized voice commands, in some cases in conjunction with recognition of the particular passenger (such as via recognition of a mobile phone, face recognition or other means), to provide passenger request input to the EUDA system for elevator travel or other operations.
In some embodiments, the EUDA system can sense conditions supporting triggering of an audible or inaudible alarm or a wireless alarm such as when a dangerous condition for a passenger is sensed. In some embodiments, the EUDA can recognize the presence of more than one passenger in the elevator car and then can implement special sensing and analysis protocols to provide protection or alarms for one or more passengers (such protocols may include monitoring passenger behavior to detect threats or other unacceptable behavior by one of the passengers). In some embodiments, the EUDA system may also activate voice recognition when more than one passenger is detected in the elevator car so that the voice recognition can recognize and alert if a passenger verbally calls out or requests help or assistance or provides other recognizable verbal cues for the EUDA system.
In some embodiments, the EUDA system can modify the existing elevator controller protocol systems, such as an existing “down collective”, “up collective”, “full collective”, “single action push button (SAPB)”, or other protocol, and thereby have the elevator system operate according to more sophisticated or customized protocols as recommended by the EUDA software or elevator management. In some embodiments, the protocols implemented by the EUDA system may change by time of day, day of week, or according to other sensed conditions relating to the elevator system.
Aspects of the present invention comprise a method of upgrading an existing elevator system wherein the existing elevator system comprises an elevator car and a first elevator controller that processes signals from first passenger input devices and directs travel of the elevator car in accordance with at least one elevator command protocol and wherein the method of upgrading the existing elevator system comprises installing an independent control device in functional communication with the existing elevator system. Further aspects of the present invention may comprise one or more methods of this paragraph (or other paragraphs) wherein the independent control device receives signals from a second set of passenger input devices (which, in some embodiments, may receive or send and receive communications from passenger mobile electronic devices). Further aspects of the present invention may comprise one or more methods of this paragraph (or other paragraphs) wherein the independent control device processes the signals from the second set of passenger input devices and sends command signals to the first elevator controller such that the first elevator controller causes the elevator car to travel vertically to floors in accordance with the command signals sent by the independent control device. Further aspects of the present invention may comprise one or more methods of this paragraph (or other paragraphs) wherein the first elevator controller maintains safety and operational control of the elevator car notwithstanding causing the elevator car to travel in accordance with the command signals sent by the independent control device. Further aspects of the present invention may comprise one or more methods of this paragraph (or other paragraphs) wherein the independent control device may direct the first elevator controller to cause the elevator car to travel according to an elevator command protocol different from a protocol followed by the first elevator controller without the intervention of the independent control device. Further aspects of the present invention may comprise one or more methods of this paragraph (or other paragraphs) wherein the independent control device may direct the first elevator controller to cause the elevator car to travel according to an elevator command protocol different from a command protocol to which the first elevator controller is configured prior to the installation of the independent control device in functional communication with the first elevator controller. Further aspects of the present invention may comprise one or more methods of this paragraph (or other paragraphs) wherein the independent control device may direct the first elevator controller to cause the elevator car to travel in accord with one or more of the protocols of President, SAPB, Down Collective, Up Collective, and or Full Collective. Further aspects of the present invention may comprise one or more methods of this paragraph (or other paragraphs) wherein the
In some embodiments, aspects of the present invention comprise methods of upgrading or customizing the operating command protocols of an existing elevator system by implementing an independent control device that receives passenger requests and/or target floor designations, processes those requests or designations using an operating command protocol different from a protocol the existing elevator system is configured to implement without the intervention of the independent control device, and issuing elevator travel commands to the existing elevator system according to the upgraded or customized operating command protocols while allowing the existing elevator system to continue to operate according to its existing safety and operational protocols. Such upgraded or customized operating command protocols may include President, SAPB, Down Collective, Up Collective, and or Full Collective or other known or customized protocols. The independent control device may be relatively easily modified by changing or upgrading the software of the control device. Such changing or upgrading may be accomplished by a variety of known techniques such as remote upgrading via the internet or other communications system or local upgrading of software. Since the independent control device does not affect the existing safety and operational systems and protocols of the existing elevator system, changes or upgrades to the software of the independent control device may be made without affecting the mechanical and safety operations of the existing elevator system.
For clarity, in some embodiments, the components of the independent system may be described as an add-on system (or a system “piggy backed”) onto the existing elevator control system. Thus, users may use either the independent system or the existing system to input calls or instructions. If a passenger places a service call at a first system floor device, the call made via the existing floor device buttons will go directly to the existing (first) elevator controller and the elevator response to that service call be governed by the protocols of that (first) elevator controller, while passenger service calls placed through the EUDA system will go to the independent control device and the elevator travel itinerary may be controlled by the protocols or other software of the independent elevator controller—while safety and operational controls are still handled by the existing elevator controller. Additionally, if a passenger places a floor destination designation via the first system car device, the floor destination designation placed via the existing car device buttons will go directly to the existing (first) elevator controller and the elevator response to that floor destination designation may be governed by the protocols of the (first) elevator controller. Alternatively, if a passenger places a floor destination designation via the second (independent) system (such as via communication with a second (independent) car device and/or a second (independent) floor device and/or another second (independent) device such as by signals from the passenger mobile device to the second (independent) component(s), the elevator travel itinerary may be controlled by the protocols or other software of the independent elevator controller—while safety and operational controls are still handled by the existing elevator controller. In some such embodiments then, the elevator operates according to the protocols of the first elevator system when passenger signals are received via the first elevator system input devices and operates according to the protocols of the independent second elevator (or EUDA) system when passenger signals are received via the independent second (or EUDA) system.
In some embodiments, aspects of the present invention may comprise a system wherein an independent component, in some instances termed as “independent health device may be attached to an elevator system, may be configured to be in data communications with a vertical position sensing system and may monitor and store performance data of the elevator car. In some embodiments the independent health device may be in functional communications with the existing elevator system so as to receive (and possibly store) data representing each call for service received by the elevator system, each target floor destination received by the system, each target floor destination received by the system in association with a particular service call, and performance data relating to the elevator system. The performance data may comprise one or more of: each call for elevator service received by the system, each target floor destination, each target floor destination in association with a call for elevator service, the actual time of travel of the elevator for each service run, the time and date of each operation of the elevator system, the speed of each movement of the elevator car, the accumulated travel time of the elevator car, the accumulated travel distance of the elevator car, any alarms generated by any component of the elevator system, the identity and travel history of each elevator passenger in the elevator, the accuracy of the stopping position of the elevator car at each floor, the operation of the elevator doors, the on or off condition of the lights in the elevator. The independent health device may analyze aspects of the performance data, including analyzing in light of predetermined performance thresholds and store the analyzation results. The independent health device may communicate performance data and/or analyzation results with certain devices of the first elevator system and/or with devices not a part of the first elevator system. In some embodiments, the independent health device may be in functional communications with or comprise an independent vertical position system independent of the first or existing elevator vertical positioning sensing system. In some embodiments, the independent health device may serve a role of monitoring elevator system performance, but not controlling elevator operations. In some embodiments, the independent health device may serve as an elevator monitoring system independent of otherwise existing elevator systems. In some embodiments the independent health device may generate and/or communicate alarms to components outside the basic functional components of the elevator system when certain analytic computations of the independent car device indicate that aspects of the performance data have exceeded or subceeded predetermined performance thresholds. In some embodiments such alarms are automatically communicated to components outside the basic functional components of the elevator system. In some embodiments such alarms may serve to halt or minimize operation of the elevator system. In some embodiments the independent health device may generate and communicate periodic performance reports of the elevator system.
Although the invention has been described with reference to specific embodiments, it will be understood by those skilled in the art that various changes can be made without departing from the spirit or scope of the invention. Accordingly, the disclosure of embodiments is intended to be illustrative of the scope of the invention and is not intended to be limiting. It is intended that the scope of the invention shall be limited only to the extent required by the appended claims. To one of ordinary skill in the art, it will be readily apparent that the systems and methods discussed herein may be implemented in a variety of embodiments, and that the foregoing discussion of certain of these embodiments does not necessarily represent a complete description of all possible embodiments. Rather, the detailed description of the drawings, and the drawings themselves, disclose at least one preferred embodiment, and may disclose alternative embodiments.
