A detailed description of one or more embodiments of the disclosed apparatus and method are presented herein by way of exemplification and not limitation with reference to the Figures.
The tension member 107 engages the machine 111, which is part of an overhead structure of the elevator system 101. The machine 111 is configured to control movement between the elevator car 103 and the counterweight 105. The position reference system 113 may be mounted on a fixed part at the top of the elevator shaft 117, such as on a support or guide rail, and may be configured to provide position signals related to a position of the elevator car 103 within the elevator shaft 117. In other embodiments, the position reference system 113 may be directly mounted to a moving component of the machine 111, or may be located in other positions and/or configurations as known in the art. The position reference system 113 can be any device or mechanism for monitoring a position of an elevator car and/or counter weight, as known in the art. For example, without limitation, the position reference system 113 can be an encoder, sensor, or other system and can include velocity sensing, absolute position sensing, etc., as will be appreciated by those of skill in the art.
The controller 115 is located, as shown, in a controller room 121 of the elevator shaft 117 and is configured to control the operation of the elevator system 101, and particularly the elevator car 103. For example, the controller 115 may provide drive signals to the machine 111 to control the acceleration, deceleration, leveling, stopping, etc. of the elevator car 103. The controller 115 may also be configured to receive position signals from the position reference system 113 or any other desired position reference device. When moving up or down within the elevator shaft 117 along guide rail 109, the elevator car 103 may stop at one or more landings 125 as controlled by the controller 115. Although shown in a controller room 121, those of skill in the art will appreciate that the controller 115 can be located and/or configured in other locations or positions within the elevator system 101. In one embodiment, the controller may be located remotely or in the cloud.
The machine 111 may include a motor or similar driving mechanism. In accordance with embodiments of the disclosure, the machine 111 is configured to include an electrically driven motor. The power supply for the motor may be any power source, including a power grid, which, in combination with other components, is supplied to the motor. The machine 111 may include a traction sheave that imparts force to tension member 107 to move the elevator car 103 within elevator shaft 117.
Although shown and described with a roping system including tension member 107, elevator systems that employ other methods and mechanisms of moving an elevator car within an elevator shaft may employ embodiments of the present disclosure. For example, embodiments may be employed in ropeless elevator systems using a linear motor to impart motion to an elevator car. Embodiments may also be employed in ropeless elevator systems using a hydraulic lift to impart motion to an elevator car.
The elevator system 101 may be operably connected to one or more computing devices, such as a system controller 206. The system controller 206 may be configured to control dispatching operations for one or more elevator cars 103 associated with one or more elevator systems 101. It is understood that the elevator system 101 may utilize more than one system controller 206. Although three elevator systems 101 are shown in
The system controller 206 may include a processor 260, memory 262 and communication module 264, as shown in
Also shown in
Each mobile device 208 may transmit an elevator call 302 to the system controller 206 and the system controller 206 will move an elevator car 103 in response to the elevator call 302. The elevator call 302 may include a “boarding floor” and a “destination floor.” The “boarding floor” is where the person with the mobile device 208 desires to board the elevator car 103 and the “destination floor” is where the person with the mobile device 208 intends to travel. In one embodiment, the elevator call 302 may only include the “destination floor” and the “boarding floor” may be automatically determined by the elevator system 101. Embodiments herein generate a graphical user interface on the mobile device 208 through an application 255. The mobile device 208 may transmit an elevator call 302 through an application 255.
The mobile device 208 and the system controller 206 communicate with one another. For example, the mobile device 208 and the system controller 206 may communicate with one another when proximate to one another (e.g., within a threshold distance). The mobile device 208 and the system controller 206 may communicate over a wireless network, such as 802.11x (Wi-Fi), short-range radio (Bluetooth), cellular, satellite, etc. In some embodiments, the system controller 206 may include, or be associated with (e.g., communicatively coupled to) a networked element, such as kiosk, beacon, hall call fixture, lantern, bridge, router, network node, door lock, elevator control panel, building intercom system, etc. The networked element may communicate with the mobile device 208 using one or more communication protocols or standards. For example, the networked element may communicate with the mobile device 208 using near field communications (NFC). A connection between the mobile device 208 and the system controller 206 may be direct between mobile device 208 and system controller 206 or it may be through a web service. The connection also may include security elements such as VPN or authentication or encryption. In other embodiments, the system controller 206 may establish connection with a mobile device 208 that is inside and/or outside of the building 202 in order to detect a location of the mobile device 208. A location of the mobile device may be determined using various technologies including GPS, triangulation, trilateration, signal strength detection, accelerometer detection, gyroscopic detection, or barometric pressure sensing by way of non-limiting example. The triangulation and trilateration may use various wireless technologies including but not limited to Wi-Fi and Bluetooth. In example embodiments, the mobile device 208 communicates with the system controller 206 over multiple independent wired and/or wireless networks. Embodiments are intended to cover a wide variety of types of communication between the mobile device 208 and system controller 206, and embodiments are not limited to the examples provided in this disclosure. Communication between the mobile device 208 and the system controller 206 will allow the system controller 206 to determine the location of the mobile device 208 in relation to the elevator system 101. The location of the mobile device 208 may be communicated to the system controller 206 through a plurality of sensors 205, discussed further below.
Each elevator system 101 may also include a sensor 205 configured to detect whether a mobile device 208 has entered the elevator car 103. In an embodiment, the sensor 205 may be located on the elevator car 103. The system controller 206 is in electronic communication with each sensor 205 through a wired connection and/or wireless connection. In an alternative embodiment, each sensor may be in indirect communication with the system controller 206 through the mobile device 208. In a non-limiting example, if the sensors 205 are a Bluetooth beacon, then the mobile device 208 can detect when it is in proximity of the sensor 205, then the mobile device 208 can communicate with the system controller 206 that it is in the elevator car 103.
Further, although only one sensor 205 is shown per elevator car 103 for ease of illustration it is understood that each elevator car 103 may contain one or more sensors 205. Each sensor 205 may also be configured to detect operational data of the elevator car 103, such as for example, elevator door position (e.g. open/closed), elevator car location, speed, voltage, vibration, acceleration, noise, deceleration, jerk, and any other performance parameter of any component of the elevator system 103 known to one of skill in the art.
The sensors 205 detect the presence of an individual in an elevator car 103 and identify the individual using various sensing technology, such as, for example Wi-Fi transceivers, Bluetooth transceivers, radio transceivers, visual recognition cameras, people counters, microphones, etc. to detect persons and/or mobile devices entering and leaving the elevator car. The type and nature of sensors 205 within the sensor system 101 is not limited to the embodiments disclosed herein. The mobile device 208 and the sensors 205 communicate with one another. For example, the mobile device 208 and the sensors 205 may communicate with one another when proximate to one another (e.g., within a threshold distance). The mobile device 208 and the sensors 205 may communicate over a wireless network, such as 802.11x (Wi-Fi), ZigBee, Z-Wave and short-range radio (Bluetooth).
In an embodiment, the sensors 205 may include a Wi-Fi transceiver to connect to a mobile device 208 when the mobile device 208 enters the elevator car 103 in order to identify the mobile device 208. In another embodiment, the sensors 205 may include a Bluetooth transceiver to connect to a mobile device 208 when the mobile device 208 enters the elevator car 103 in order to identify the mobile device 208. The sensors 205 are configured to detect a distance between the elevator car 103 and the mobile device 208 to determine whether the mobile device 208 is entering and/or leaving the elevator car 103. The sensors 205 may be configured to detect a distance between the elevator car 103 and the mobile device 208 through wireless signal strength detection.
Communication between the mobile device 208 and the sensors 205 can be one-way or two-way communication. In one example, if Bluetooth is utilized then the mobile device 208 may advertise a Bluetooth signal and the sensors 205 may receive it. In another example, the sensors 205 may advertise a Bluetooth signal and the mobile device 208 may receive it. In another example, there may be two-way Bluetooth communication between the sensors 205 and the mobile device 208. In another example, a Wi-Fi transceiver (i.e. sensor 205) may be placed in an elevator car and the mobile device may detect the Wi-Fi beacon frame as part of the 802.11x protocol as well as the received signal strength of that beacon frame to approximate the distance between the Wi-Fi transceiver and the mobile device 208 but not connect to the Wi-Fi signal. In another example, the mobile device 208 may actively send a probe request looking for Wi-Fi transceivers, then a Wi-Fi transceiver (i.e. sensor 205) located in an elevator car may extract the MAC address of the mobile device 208 from the probe request and approximate distance between the Wi-Fi transceiver and the mobile device 208 from received signal strength.
In another embodiment, the mobile device 208 and the sensors 205 may communicate over a non-radio frequency network. In an example the mobile device 208 and the sensors 205 may communicate through audio transmission, such as, for example a high frequency audio transmission. The mobile device 208 may emit a chirp signature between 15 kHz-20 kHz that one or more microphones (i.e. sensor 205) can detect and extract a signature to determine which mobile device 208 is present. In this example, Audio gain at speaker may be measured to a distance between the microphone and the mobile device 208 may be determined in response to the audio gain. Advantageously, more microphones may help better determine distance. Alternatively, the speakers (i.e. sensors 205) may be located in the elevators car 103 and may emit the high frequency audit for the mobile device 208 to detect. Advantageously, one or more speakers may be help better determine distance.
The elevator call control system 200 may also include an indoor positioning system 300 comprising one or more building sensors 310 in electronic communication with the system controller 206. The building sensors 310 may be located throughout the building 202. Each building sensor 310 may be configured to emit and/or detect a wireless signal. The building sensor 310 may be configured to emit a wireless signal that may be detected by the mobile device 208. The building sensor 310 may be able to detect a wireless signal emitted by mobile device 208. In an embodiment, a building sensor 310 may be a door lock that controls access to a room within the building 202. In an embodiment, a building sensor 310 may be a wireless access protocol device that provides Wi-Fi access to computing devices throughout the building 202.
The building sensors 310 may detect the location of the mobile device 208 within a building 202 using various sensing technology, such as, for example Wi-Fi transceivers, Bluetooth transceivers, radio transceivers, etc. to detect the presence of mobile devices 208 within the building 202. The type and nature of building sensors 310 within the sensor system 101 is not limited to the embodiments disclosed herein. The mobile device 208 and the building sensors 310 communicate with one another. For example, the mobile device 208 and the building sensors 310 may communicate with one another when proximate to one another (e.g., within a threshold distance). The mobile device 208 and the building sensors 310 may communicate over a wireless network, such as 802.11x (Wi-Fi), ZigBee, Z-Wave and short-range radio (Bluetooth).
In an embodiment, the building sensors 310 may include a Wi-Fi transceiver to connect to a mobile device 208 when the mobile device 208 is located within a threshold distance in order to determine the location of the mobile device 208. In another embodiment, the building sensors 310 may include a Bluetooth transceiver to connect to a mobile device 208 when the mobile device 208 is located within a threshold distance in order to determine the location of the mobile device 208. The building sensors 310 may be configured to detect a distance between each of the building sensor 310 and the mobile device 208 through wireless signal strength detection. The wireless signal strength detected between the mobile device 208 and a single building sensor 310 may be enough to approximate a location of the mobile device 208 or the indoor positioning system 300 may utilize three or more building sensors 310 to triangulate the position of the mobile device 208 utilizing the wireless signal strength detected between the mobile device 208 and each of the three building sensors 310.
Communication between the mobile device 208 and the building sensors 310 can be one-way or two-way communication. In one example, if Bluetooth is utilized then the mobile device 208 may advertise a Bluetooth signal and the building sensors 310 may receive it. In another example, the building sensors 310 may advertise a Bluetooth signal and the mobile device 208 may receive it. In another example, there may be two-way Bluetooth communication between the building sensors 310 and the mobile device 208. In another example, a the building sensor 310 may be a Wi-Fi transceiver (i.e., a wireless access protocol device) and the mobile device 208 may detect the Wi-Fi beacon frame as part of the 802.11x protocol as well as the received signal strength of that beacon frame to approximate the distance between the Wi-Fi transceiver and the mobile device 208 but not connect to the Wi-Fi signal. In another example, the mobile device 208 may actively send a probe request looking for Wi-Fi transceivers, then a Wi-Fi transceiver (i.e. building sensor 310) may extract the MAC address of the mobile device 208 from the probe request and approximate distance between the Wi-Fi transceiver and the mobile device 208 from received signal strength.
In one embodiment, the mobile device 208 may determine a distance between the mobile device 208 and each of the building sensors 310 and transmit that distance to the system controller 206 to determine the location of the mobile device 208. In another embodiment, the indoor positioning system 300 may determine a distance between the mobile device 208 and each of the building sensors 310 and transmit that distance to the system controller 206 to determine the location of the mobile device 208. The location of the mobile device 208 may be determined by the mobile device 208 or by the indoor positioning system 300. In one embodiment, the mobile device 208 may determine a distance between the mobile device 208 and each of the building sensors 310, then the mobile device 208 may use that distance to determine the location of the mobile device 208 to transmit to the system controller 206. In another embodiment, the indoor positioning system 300 may determine a distance between the mobile device 208 and each of the building sensors 310, then the indoor positioning system 300 may use that distance to determine the location of the mobile device 208 to transmit to the system controller 206. A global positioning system (GPS) or any other known location determining method may also be utilized to determine a location of the mobile device.
Referring now to
The application 255 may include various user settings 230 that may be adjusted through the graphical user interface 178, as shown in
At block 504 of method 500, an elevator call 302 is received from a mobile device 208. The elevator call 302 including a destination request to travel from a boarding floor to a destination floor. At block 506, a first elevator car 103a is assigned to the elevator call 302. At block 508, an alert is activated on the mobile device 208 that the first elevator car 103a has been assigned to the elevator call 302, at 402.
At block 510, it is determined that the first elevator car 103a cannot serve the elevator call 302. It may be determined that the first elevator car 103a cannot serve the elevator call 302 by determining that the first elevator car 103a has encountered an operational fault (e.g., broken down) and the first elevator car 103a cannot serve the elevator call 302 due to the operation fault. It may also be determined that the first elevator car 103a cannot serve the elevator call 302 by determining that the first elevator car 103a is delayed in traffic and the first elevator car 103a cannot serve the elevator call 302 due to being delaying in traffic. It may also be determined that the first elevator car 103a cannot serve the elevator call 302 by determining that the mobile device 208 has not entered the first elevator car 103a within a selected period of time waiting at the boarding floor and the first elevator car 103a cannot serve the elevator call 302 due to the mobile device 208 not having entered the first elevator car 103a within the selected period of time waiting at the boarding floor. Thus, the first elevator car 103a may now be free to serve additional elevator calls 302 after the selected period of time waiting at the boarding floor.
It may also be determined that the first elevator car 103a cannot serve the elevator call 302 because a user setting is violated. The application 255 may notify a user of the mobile device 208 that a user setting 230 is violated by the first elevator car 103. The application 255 may automatically attempt to find a new elevator car 103 that does not violate a user setting 230 or the application 255 may request a user input to allow the violation of the user setting 230 and keep the first elevator car 103a assigned to the elevator call 302 or the application 255 may request an adjustment to a user setting 230. The method 500 may also include: detecting a location of the mobile device 208. It may also be determined that the first elevator car 103a cannot serve the elevator call 302 by determining the first elevator car 103a will be waiting at the boarding floor greater than a selected period of time in response to the location of the mobile device 208 and the first elevator car 103a cannot serve the elevator call 302 due to the first elevator car 103a being tied up for too long at the boarding floor waiting on the individual carrying the mobile device 208 to arrive and board the first elevator car 103a.
The location of the mobile device 208 may be detected by: connecting a building sensor 310 to the mobile device 208 via at least one of Wi-Fi and Bluetooth; and determining a distance between the building sensor 310 and the mobile device 208, which may be done with three or more building sensors 310 to triangulate the position of the mobile device 208.
The location of the mobile device 208 may be detected by: detecting, using a building sensor 310, a wireless signal of the mobile device 208 where the building sensor 310 does not connect to the wireless signal; and determining a distance between the building sensor 310 and the mobile device 208, which may be done with three or more building sensors 310 to triangulate the position of the mobile device 208.
The location of the mobile device 208 may be detected by: detecting a beacon transmitted by a building sensor 310 using the mobile device 208; and determining a distance between the building sensor 310 and the mobile device 208 in response to a strength of the beacon, which may be done with three or more building sensors 310 to triangulate the position of the mobile device 208. A global positioning system (GPS) or any other known location determining method may also be utilized to determine a location of the mobile device.
The method 500 may further comprise: receiving a desired passenger wait time from the mobile device 208. The desired passenger wait time may depict how long an individual carrying the mobile device 208 is willing to wait for the first elevator car 103a to arrive at the boarding floor. The location of the mobile device 208 may be detected by: determining that the first elevator car 103a will not arrive at the boarding floor within the desired passenger wait time and the first elevator car 103a cannot serve the elevator call 302.
It may also be determined that the first elevator car 103a cannot serve the elevator call 302 by: determining a passenger wait time of the first elevator car 103a to arrive at the boarding floor; determining a passenger wait time of the second elevator car 103b to arrive at the boarding floor; determining that the passenger wait time of the first elevator car 103a is greater than the passenger wait time of the second elevator car 103b and that the first elevator car 103a cannot serve the elevator call 302 due to the first elevator car 103a is greater than the passenger wait time of the second elevator car 103b. The system controller 206 may automatically switch over to the second elevator car 103b (or any other elevator car 103) if the second elevator car 103b has a shorter passenger wait time than the first elevator car 103a. The system controller 206 may automatically switch over to the second elevator car 103b (or any other elevator car 103) if the second elevator car 103b has a shorter passenger wait time than the first elevator car 103a by a passenger wait time threshold that was received from the mobile device 208. The passenger wait time threshold may be saved in the user settings 230. For example, the individual carrying the mobile device 208 (i.e., the passenger) may only wish that the system controller 206 transfer the elevator call 302 to the elevator car 103b if the second elevator car 103b can arrive 30 seconds earlier (e.g., passenger wait time threshold) than the first elevator car 103a.
The system controller 206 may request confirmation from the individual carrying the mobile device 208 to switch over to the second elevator car 103b (or any other elevator car 103) if the second elevator car 103b has a shorter passenger wait time than the first elevator car 103a. The system controller 206 may alert the individual of the shorter passenger wait time by activating an alert on the mobile device 208 indicating that the second elevator car 103b has a shorter passenger wait time than the first elevator car 103a, as shown in
At block 512, a second elevator car 103b is assigned to the elevator call 302. At block 514, an alert is activated on the mobile device 208 indicating that the second elevator car 103b has been assigned to the elevator call 302, as shown at 404. The alert may be visual, audible, and/or vibratory. As shown in
