This application claims the benefit of European Application No. 17305650.8, filed Jun. 2, 2017, which is incorporated herein by reference in its entirety.
The present disclosure relates generally to passenger conveyor systems, and more particularly, to passenger conveyor maintenance and operational diagnostics.
Passenger conveyor systems such as elevator systems, escalator systems, etc., often require inspection and/or maintenance to ensure passengers are provided continuous and uninterrupted service. A technician may be required to visit buildings installed with passenger conveyor systems and perform routine inspections of the passenger conveyors (e.g., elevator cars, escalator stairs, etc.) to ensure they are in working order. However, a technician can be required to put forth extensive time and effort in order to visit every passenger conveyor system that is maintained by a maintenance service organization. In addition, passengers are the first to realize an operating fault, but may be unaware how to inform a building manager and/or technician of the operating fault. Consequently, there may be an excessive delay from the time at which the operating fault occurs until the time at which the operating fault is ultimately resolved.
According to a non-limiting embodiment, a passenger conveyor performance rating system is provided that includes a user device and a computing server. The user device obtains geographical information of the passenger conveyor system and displays a graphical user interface. The graphical user interface receives a first input indicating an operating performance of an individual passenger conveyor and a second input indicating at least one operation fault of the individual passenger conveyor.

The following descriptions should not be considered limiting in any way. With reference to the accompanying drawings, like elements are numbered alike:
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 term “about” is intended to include the degree of error associated with measurement of the particular quantity based upon the equipment available at the time of filing the application. For example, “about” can include a range of ±8% or 5%, or 2% of a given value.
The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present disclosure. As used herein, the singular forms “a”, “an” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will be further understood that the terms “comprises” and/or “comprising,” when used in this specification, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, element components, and/or groups thereof.
Turning now to an overview of technologies that are more specifically relevant to aspects of the present teachings, one solution to resolve the problems of reducing the time and excessive workloads of technicians described above is to encourage passengers within the elevator to inform the technician or service maintenance organization of a needed repair, replacement, inspection, etc. In this manner, maintenance can be performed in a timely manner from when the issue or operating fault is first observed. Current solutions include posting a phone number (or website) in or near the elevator with the intention that the passenger will notice the phone number and call the technician. However, passengers may be hesitant to actively contact the technician, or may not notice the contact information before the ride or service is completed (e.g., elevator reaches the desired floor or the escalator reaches the desired platform). Accordingly, an improved means for reporting an operating performance of a passenger conveyor system is desirable.
Turning now to an overview of the aspects of one or more embodiments of the inventive teachings, the above-described shortcomings of the prior art are addressed by providing a passenger conveyor performance rating system that includes a maintenance computing server which exchanges data with a user device to determine an operational performance of a passenger conveyor included in a passenger conveyor system.
In one or more non-limiting embodiments, the user device is a passenger's mobile terminal device. The passenger's mobile terminal device can be installed with a software application (i.e., App) capable of obtaining identification (ID) information of the passenger conveyor (e.g., elevator, escalator, etc.) included in the passenger conveyor system, and obtaining geographical information of the passenger conveyor system (e.g., street address of the building hosting the passenger conveyor system). The App can display a graphical user interface (GUI) on the mobile terminal device. The GUI can receive a first input from the passenger indicating an operating performance of a given passenger conveyor (e.g., the elevator car containing the passenger), and a second input indicating at least one operation fault (e.g., noises, vibration, stoppage) of the identified passenger conveyor.
A computing server (e.g., maintenance server) can receive the data provided by the mobile terminal device and generate a graphical map displaying the geographical location of the passenger conveyor system experiencing an operation fault based on the geographical information. In this manner, a technician can conveniently be informed of a maintenance issue that requires further investigation and can be quickly routed to the location of the passenger conveyor system. The mobile terminal device can also provide the computing server with contact information (e.g., telephone number of building that contains faulty elevator system, email address of building manager, mailing address of building, etc.) associated with the passenger conveyor system experiencing the operating fault. Accordingly, the computing server can automatically send a maintenance inquiry (e.g., an email to the manager of the building containing the faulty elevator system, a telephone call to the building manager, a text message to the building manager, etc.) proposing maintenance service of an identified faulty passenger conveyor include in a given passenger conveyor system.
With reference now to
The processor 106 can be included in a computing system operated by a maintenance service company, for example, or can be installed in a mobile computing device.

The computing server 202 is a computing device capable of providing functionality for other programs or devices, typically referred to as “clients”. The computing server 202 can be implemented as a local on-site server, a remotely located service-operated server, or a cloud computing server. The computing server 202 can store setup parameters for select functions. In some embodiments, the setup parameters can be stored in a controller. In some embodiments, there may be a simplified failover functionality located in the controller in the event that there is a connection loss between the controller and the computing server 202.
In some embodiments, operational metrics may be collected at the computing server 202 across a portfolio of multiple units, sites, or groups. The metrics may be analyzed by, e.g., the backend computer 206, to provide a broad view of the portfolio. For example, the analysis may indicate trends and may be used to respond to needs (e.g., product needs or functionality needs). The analysis may also be used to facilitate diagnostic or troubleshooting capabilities. Metrics may be used to trigger or enhance the accuracy of sales proposals. Diagnostics and/or detect faults may be used to provide or schedule maintenance activities, such as preventive maintenance activities. In some embodiments, interface protocols configured to operate with new devices, for example, may be stored in the computing server 202 and used by a local controller.
In some embodiments, functional upgrades for diagnostics, prognostics, and remote repair/rescue functions can be deployed to customers as they are released and deployed into the computing server 202. Functionality may be developed at the backend computer 206 (installed at a server location 207 remotely located from the mobile terminal device 204) and deployed to the computing server 202. One or more tests may be executed to ensure that the functionality satisfies operational or safety requirements.
In some embodiments, a modernization of cloud supported controllers (not shown) may be provided. The controllers can utilize a computing server 202 to enable new features or support new devices/equipment. Before or during the modernization, the controllers may receive updates via the computing server 202 to support interface protocols to new equipment and/or add new functions/capabilities. For example, if a new fixture is added requiring a new interface, a controller may enable the new functionality from the computing server 202 once the new fixture has been integrated into the computing network 200 without requiring an upgrade of software on the controller. As yet another example, a new dispatching algorithm may be implemented from the cloud to optimize traffic during the modernization phase of the project.
The mobile terminal device 204 is capable of communicating with the computing server 202 over one or more connections, channels, or links facilitated by a network interface. The mobile terminal device 204 includes a smartphone 204, for example, which can be located in or near a passenger conveyor location 205, and is capable of electrically communicating with the computing server 202 via a connection 208. The connection 208 can adhere to one or more communication protocols, standards, or the like. For example, the connection 208 can adhere to telephone, cellular, Wi-Fi, Ethernet, satellite, or cable communications. In some embodiments, the connection 208 may be constant or persistent. Although the mobile terminal device 204 will be referred to as a smartphone 204 hereinafter, the mobile terminal device 204 can include any mobile device capable of facilitating interaction between one or more stored software applications (i.e., apps) and the computing server 202. For example, the mobile terminal device 204 can also include a computer tablet, a laptop computer, a smart watch, etc.
The smartphone 204 includes a display 220, and other components capable of detecting data, information, or objects such as, for example, sound, vibrations, images, etc. The smartphone 204 stores in memory a passenger conveyor performance rating software application (referred to herein as a performance rating app). The performance rating app can be manually invoked by the passenger or can be automatically invoked when the smartphone 204 detects one or more operating conditions of a passenger conveyor that is servicing the passenger. For example, a passenger riding a particular elevator car may experience abnormal noises and or vibrations. The passenger's smartphone 204 can detect the noises via a microphone and/or the vibrations via an accelerometer. In response to detecting the noises and/or vibrations, the smartphone 204 can automatically launch the performance rating app.
The performance rating app obtains inputs from the passenger which rates the operating performance of a passenger conveyor system and/or a specific passenger conveyor included in the passenger conveyor system. The performance rating app and the smartphone 204 itself can also determine geographical information of a particular passenger conveyor system and/or identification (ID) information of a passenger conveyor (e.g., elevator, escalator, etc.) included in a given passenger conveyor system. For instance, the performance rating app can prompt a passenger to input geographical information such as, for example, a street address, building name, global positioning system (GPS) coordinates, or store name. The geographical information is then exchanged with the computing server 202 via connection 208.
As described above, functionality may be (re)located to a computing server 202 (e.g., maintenance server 202). In terms of passenger conveyor systems, for example, such functionality may include dispatch functions for one or more passenger conveyor devices, mobile terminals, operational mode determinations, diagnostic functions, special contract features, etc. Regarding dispatch functions, in some embodiments a passenger request for service received at, e.g. a hall box located on a particular floor of a building, may be communicated to the computing server 202. In response to the request, the computing server 202 may transmit a command that directs a specified elevator car to relocate to that particular floor to fulfill the service request.
In some embodiments, a local controller (not shown) can maintain some functionality, and as such, may include hardware and computing resources to support such functionality. The controller can include hardware and/or software to communicate with the computing server 202. For example, the controller can exchange data and commands with the computing server 202 to perform control functions. Accordingly, additional dispatch functions may include initiating phone calls, text messages, emails, or other types of communication.
The computing server 202 can also store a map Application Programming Interface (API) and/or map graphics engine to perform various geographical calculations and map generation operations based on geographical information provided by the smartphone 204. For example, the smartphone 204 may obtain GPS information, and building identification (ID) information. The GPS information is obtained from traditional GPS systems as understood by one of ordinary skill in the art. The building ID information can be obtained from a building's local wireless system and/or from a passenger conveyor system configured to wirelessly broadcast its own ID information. The building ID information may also be obtained by using a camera installed on the smartphone 204 to scan barcodes or Quick Response (QR) codes. Based on the building ID information, the computing server 202 can generate a geographical map 230 with indicators 232 that identify the location of one or more passenger conveyor systems. The map 230 can then be displayed on a screen of the backend computer 206.
The computing server 202 may also be in signal communication with a mobile terminal device 250 possessed by a maintenance technician 252. The performance ratings received from a passenger's smartphone 204 can be used by the computing server 202 to diagnose a particular passenger conveyor system and/or individual passenger conveyor included in the passenger conveyor system. When an operation fault is diagnosed, the computing server 202 can execute a dispatch function that actively updates a technician's maintenance schedule in real-time and provides the technician with a map indicating the location of the passenger conveyor system experiencing the operating fault. In this manner, the technician can quickly and conveniently visit the building containing the faulty passenger conveyor system.
The geographical information received from the smartphone 204 can also be used to obtain additional contact information (e.g., telephone number, email address, etc.) of the building containing the faulty passenger conveyor system. For example, scan codes can be located on a respective passenger conveyor (e.g., in an elevator car) and can identify the building address, the name of the building or store, the contact information of building manager, a serial number of the passenger conveyor system, the manufacturer of the passenger conveyor system and/or a particular passenger conveyor (e.g., an individual elevator car or escalator) among a plurality of passenger conveyors included in a passenger conveyor system. Based on the contact information, the server can execute a dispatch function which includes automatically sending a maintenance inquiry based on the contact information. The maintenance inquiry includes, for example, a proposed maintenance service of an identified faulty passenger conveyor. For instance, in response to determining a passenger's operating performance rating indicates a faulty elevator car, the computing server 202 can automatically send a service inquiry (e.g., an email, text message, telephone call, etc.) to the service manager of the building containing a faulty elevator car identified from a passenger's smartphone 204. The service inquiry can automatically be generated to include language offering to dispatch a technician to diagnose and service the identified faulty elevator car.

The ID information described above may also be obtained by processing a scan code 306 (e.g., a bar code or QR code) located in the elevator car 302. For instance, the smartphone camera can capture an image of the scan code 306, which can then be further processed by the smartphone 204 and/or exchanged with the computing server 202, via the computing network 200, for further processing to obtain the ID information described above.
A passenger 255 can rate the operating performance of the elevator system 300 and/or the particular elevator car 302 performing the ride service using a performance rating app installed on the smartphone 204. The performance rating app may also allow the passenger 255 to input operating fault information which may have been experienced by the passenger 255 during the ride service. The fault information can include, but is not limited to, noises, vibrations, or service stoppages. The rating input, along with the ID information and fault information can be transmitted to the computing server 202, via the computing network. Based on the operating performance rating input by the passenger 255, the computing server 202 can determine whether the elevator system 300 and/or elevator car 302 is faulty, and if so, can perform various dispatch operations as described herein. In addition to recording faulty operation incidents, the computing server 202 can also record satisfactory or successful rating inputs by the passenger 255. Accordingly, health reports of the elevator system 300 can be conveniently generated, thereby facilitating the scheduling of routine inspections by a technician.
