[0001] The present invention relates to an elevator worker rear support system and an elevator worker rear support method.

Background Art

[0002] In elevator maintenance, failures and malfunctions occur due to various causes, and maintenance such as repair and parts replacement by maintenance personnel is required. Here, when it is difficult to solve the failure or malfunction only with the knowledge and experience of the maintenance personnel corresponding to the failure or malfunction, it may be necessary to request support by phone from a rear supporter. The rear supporter requested for support by the elevator maintenance personnel needs to ask the maintenance personnel for on-site information necessary for support, such as the failure state of the elevator and the investigation content at the time of requesting support. However, if all the information is obtained orally, it takes time to transmit the information, and there may be cases where the failure or malfunction cannot be solved promptly.

[0003] Patent Document 1 describes a technique in which, when maintaining a system such as computer equipment, log information of the maintenance target is transmitted to a server, and after the server analyzes the received log, a method for dealing with the problem is transmitted to the operator's terminal, thereby omitting oral communication and quickly solving failures and malfunctions.

Summary of the Invention

Problems to be Solved by the Invention

[0005] As described in Patent Document 1, when log information of equipment to be maintained is sent to a server, a large amount of log information indicating the operating status of the equipment is sent to the server, requiring the server to analyze the large amount of received log information. Consequently, the server will need time to analyze the logs, making it difficult for on-site maintenance personnel to quickly obtain the necessary information. Furthermore, on-site workers do not necessarily need information on the entire fault recovery process, but rather on how to deal with problems that are specific to the situation at hand, and automated responses based on log analysis may not provide the appropriate information.

[0006] Furthermore, the methods for troubleshooting elevators often differ depending on the model and installation environment, and each technician providing backup support is assigned to a specific model. Therefore, even if a maintenance worker calls the center where backup support personnel are on standby, the center's telephone operator needs to ask about the model being worked on and the nature of the malfunction before transferring the call from the maintenance worker to the appropriate backup support person. Consequently, the conventional method had the problem of taking a long time for the call to be connected to a backup support person who could assist with troubleshooting the model the maintenance worker was working on.

[0007] The objective of the present invention is to provide a system and method for providing support to elevator operators in the event of a malfunction, which can quickly respond to inquiries from maintenance personnel working on elevators at the site. [Means for solving the problem]

[0008] To solve the above problems, for example, the configuration described in the claims may be adopted. This invention includes several means for solving the above-mentioned problems, but one example is an elevator operator support system comprising a maintenance work terminal held by the elevator operator and a support center that responds to inquiries from the operator regarding maintenance work. Here, the maintenance work terminal comprises a terminal-side storage unit that stores the elevator's work schedule and an application program that instructs the elevator's maintenance work, a processing unit that executes the application program, and a terminal-side communication unit that communicates with the support center. The support center comprises a center-side communication unit that receives work schedules and application program logs transmitted from maintenance work terminals, a center-side storage unit that stores the work schedules and logs received by the center-side communication unit, and a rear-office support terminal that can communicate with a communication terminal held by a worker or a maintenance work terminal. When a call is made to the support center from a communication terminal or maintenance work terminal, the center-side memory unit selects a backup support terminal that matches the work schedule and log stored in it and connects it to enable communication. The connected backup support terminal then displays the work schedule and log, or log analysis results, that were transmitted from the maintenance work terminal of the relevant worker and stored in the center-side memory unit. [Effects of the Invention]

[0009] According to the present invention, when an elevator malfunctions or fails, the worker responsible for addressing the malfunction or failure can contact a support staff member, enabling the support staff member to provide quick and efficient assistance. Therefore, it has the effect of reducing the time required to address elevator malfunctions and failures. Other issues, configurations, and effects not mentioned above will be clarified by the following description of the embodiments. [Brief explanation of the drawing]

[Figure 7] This figure shows an example of the screen on a support worker's terminal during an inquiry, according to one embodiment of the present invention. [Modes for carrying out the invention]

[0011] Hereinafter, an elevator operator rear support system and elevator operator rear support method according to one embodiment of the present invention (hereinafter referred to as "this example") will be described with reference to the attached drawings.

[0012] [Outline of the elevator operator support system in case of malfunction] Referring to Figure 1, the outline of the elevator operator support system in the event of a malfunction in this example will be explained. In this example, the elevator operator support system in the event of a malfunction allows worker a, who is performing maintenance work such as repairs or inspections at a site 10 where an elevator 11 is installed, to contact the support center 20, which is the contact point for inquiries, by telephone if any problems arise during the work.

[0013] Worker A connects a maintenance terminal 100, consisting of a notebook computer or tablet, to the control panel 12 of the elevator 11 via wired or wireless connection, and performs maintenance work while checking the status of the elevator 11 and the control panel 12. The maintenance terminal 100 is pre-installed with an application program to support elevator maintenance work, and worker A performs the work based on the instructions of that application program. The application program also includes a schedule of maintenance work to be performed by worker A.

[0014] The support center 20, which is the inquiry window for maintenance work, is prepared by the company to which worker a belongs. An application program for supporting maintenance work and a storage unit 22 for storing log data transmitted from the maintenance work terminal 100 are connected to the network 21 within the support center 20. The storage unit 22 stores the logs and schedules of worker a in the processes described later. In addition, a back-end supporter terminal 200 operated by a back-end supporter is connected to the network 21 of the support center 20. A communication terminal 190 such as a smartphone possessed by worker a is connected to the back-end supporter terminal 200 by making a phone call to the support center 20, and the back-end supporter can communicate with worker a through the back-end supporter terminal 200. A plurality of back-end supporter terminals 200 are prepared in the support center 20, and the back-end supporters assigned to each back-end supporter terminal 200 are configured to support a specific model or work content for the worker a who made the phone call.

[0015] That is, when worker a makes a phone call to the support center 20 using the communication terminal 190, the support center 20 selects an appropriate back-end supporter terminal 200 based on the schedule and log of the corresponding worker a stored in the storage unit 22. Then, the back-end supporter answers the phone from worker a on the selected back-end supporter terminal 200. When the back-end supporter answers the call on the back-end supporter terminal 200, the back-end supporter opens a work-related information file such as the schedule and log of worker a on the back-end supporter terminal 200 and displays the work-related information on the screen of the back-end supporter terminal 200. In addition to the schedule and log of worker a, the analysis result of the log may also be displayed as this work-related information.

[0016] Thereby, the back-end supporter can check the state of the elevator 11 during the work of worker a while looking at the work-related information on the screen and give appropriate advice required during the work. For example, the back-end supporter can instruct worker a on parts that seem to need repair or replacement.

[0017] [Configuration of the Rear Support System for Elevator Workers] Next, referring to FIG. 2, the specific configuration of the rear support system for elevator workers in this example will be described. The rear support system for elevator workers in this example is composed of a maintenance work terminal 100 held by worker a who performs maintenance work on elevator 11, a communication terminal 190 held by worker a, and a support center 20. Note that the maintenance work terminal 100 may be provided with a communication function so that the maintenance work terminal 100 also serves as the communication terminal 190.

[0018] The elevator 11 includes a control panel 12 that controls the operation of the elevator 11 and a remote monitoring device 13 that monitors the state of the elevator 11. During the maintenance work by worker a, worker a can read the operation information and fault detection information monitored by the remote monitoring device 13 on the maintenance work terminal 100.

[0019] The maintenance work terminal 100, which is composed of a notebook computer device, a tablet terminal, etc., includes a device connection part 111, a processing part 112, a communication part 113, a display part 114, an operation part 115, and a storage part 120. The device connection part 111 acquires operation information and fault detection information from the remote monitoring device 13 of the elevator 11 by communication via a connected cable or short-range wireless communication. The acquired operation information and fault detection information are sent to the storage part 120 via the processing part 112 and stored.

[0020] The processing part 112 executes an elevator application program 121 and a remote monitoring device application program 122 held in the storage part 120 to read information from the remote monitoring device 13 and support the maintenance work of the elevator 11, etc. The communication part 113 communicates with the center-side communication part 23 of the support center 20 via the Internet or the like. Also, the communication part 113 communicates with the communication terminal 190. Note that the communication part 113 may communicate with the center-side communication part 23 via the communication terminal 190. The display unit 114 displays support information for maintenance work based on the execution of each application program in the processing unit 112. The control unit 115 registers the start and end of maintenance work, as well as the progress of the work, based on the operation of operator a.

[0021] The memory unit (terminal-side memory unit) 120 stores application programs for elevators 121 and remote monitoring devices 122, as well as application operation logs 123, communication logs 124, user information 125, work schedules 126, work-related information 127, and more. The elevator application program 121 is a group of applications that perform operational measurements and abnormality detection for equipment installed on the elevator 11. The remote monitoring device application program 122 is a group of applications that allows the remote monitoring device 13 to be operated to obtain data from the elevator 11.

[0022] The application operation log 123 is the operation history of the elevator application program 121 and the remote monitoring device application program 122. Communication log 124 is a record of communication between the elevator 11 and the maintenance work terminal 100. User information 125 is the worker number assigned to the worker who possesses this terminal. Work schedule 126 is the work schedule for worker a, who possesses this terminal. Work schedule 126 includes worker a's identification number, information about the elevator (work site) where worker a will perform work, and the details of the work, and is registered in advance before the start of work. Regarding work-related information 127, it will be explained later in Figure 3.

[0023] The communication terminal 190, which consists of a smartphone or the like, comprises a communication unit 191, a processing unit 192, a call unit 193, a display unit 194, and an operation unit 195. The communications unit 191 communicates with the outside world via telephone lines and other means. Calls to the support center 20 are also made through the communications unit 191. The processing unit 192 performs processing such as communication for phone calls and processing for display on the display unit 194. The processing unit 192 also performs communication such as phone calls based on instructions from the maintenance work terminal 100. The call unit 193 processes calls using the speaker and microphone built into the call terminal 190. The display unit 194 displays information related to the call, such as the destination of the call. The control unit 195 receives input from operator a. Furthermore, the communication terminal 190 operates in conjunction with instructions from the elevator application program 121 of the maintenance work terminal 100, and in response to a command from the maintenance work terminal 100, it displays an operation screen for making a call on the support center 20.

[0024] The support center 20 includes a storage unit 22, a center-side communication unit 23, a data processing unit 24, and a support worker terminal 200. These memory units 22, the center-side communication unit 23, the data processing unit 24, and the support worker terminal 200 are connected to the network 21 within the support center 20. The memory unit (center-side memory unit) 22 stores information such as logs received from the maintenance work terminal 100 by the center-side communication unit 23, as well as information such as the work schedule of each worker performing support work and the telephone numbers of the communication terminals 190 carried by each worker. The center-side communication unit 23 communicates with the maintenance work terminal 100 or the call terminal 190. The data processing unit 24 performs processing to analyze information such as logs stored in the storage unit 22. The data processing unit 24 also performs processing to select the support worker terminal 200 when a call is received at the support center 20.

[0025] The support terminal 200 has the function of answering and making calls from the call terminal 190, as well as the function of displaying information stored in the memory unit 22 and the analysis results from the data processing unit 24, and supports worker a who is performing maintenance work based on the displayed information.

[0026] [Example of a work-related information file] Figure 3 shows an example of work-related information 127 stored in the storage unit 120 of the maintenance work terminal 100. The example work-related information 127 shown in Figure 3 includes the worker number obtained from user information 125 indicating worker a, the work site number and work details obtained from the work schedule 126, the application used and operation log obtained from the application operation log 123, and the communication log obtained from the communication log 124. These work-related information 127 are transmitted to the support center 20 during maintenance work using the procedure described below.

[0027] [Flow of maintenance work and support processes] Figure 4 is a flowchart showing the process flow when worker a performs maintenance work on the elevator 11 at the site. First, let's assume that a malfunction occurs in the elevator 11 (Step S11). As a result, the remote monitoring device 13 of the elevator 11 notifies the maintenance work terminal 100 of the malfunction, and worker a is dispatched to the site where the elevator 11 is installed, based on instructions from the elevator monitoring center (not shown) (Step S12). Upon arriving at the site, worker a connects the maintenance work terminal 100 they are carrying to the elevator 11 and checks the malfunction status (Step S13).

[0028] Then, the maintenance terminal 100 uses an application program for elevators or an application program for remote monitoring devices to perform an investigation of the cause of failure in the processing unit 112 (step S14). In the investigation of the cause of failure by the processing unit 112 in step S14, the maintenance terminal 100 determines whether or not the cause of failure has been identified (step S15).

[0029] If the cause of the failure is identified in step S15 (YES in step S15), the maintenance work terminal 100 displays the cause of the failure identified by the display unit 114, and the worker performs the repair or replacement of the part related to the displayed cause of the failure (step S16). After completing this work, the worker confirms that the elevator is operating normally and finishes the work (step S17). This is the case when the work is completed without any support from the support center 20.

[0030] Next, we will explain the procedure when backup support is required. If the cause of the failure cannot be identified in step S15 (NO in step S15), the maintenance work terminal 100 processes the worker's schedule and the operation log of the application program into data in a predetermined format (step S21). This formatting process is performed, for example, based on the elevator application program. The formatted data is stored in the storage unit 120 of the support center 20 from the maintenance work terminal 100, and then analyzed by the data processing unit 24 (step S22). Based on the analysis results in step S22, worker a determines the cause of the accident and how to deal with it. During the analysis in step S22, data from similar past cases may be referenced, or results learned by the data processing unit 24 may be used.

[0031] Subsequently, worker a makes a telephone call to the support center 20 using the communication terminal 190. The support center 20 identifies the worker based on the caller ID number of the communication terminal 190 and selects an appropriate support terminal 200 based on the analysis results of the data processing unit 24 (Step S23: Support terminal selection process). The support center 20 then displays work-related information on the display screen of the support terminal 200. Furthermore, an appropriate support person is one who is familiar with the type of elevator 11 that the worker is performing maintenance work on. Then, the support worker associated with the support worker terminal 200 selected in the selection process makes a phone call to worker a's communication terminal 190, and the support worker who answers the phone on the support worker terminal 200 communicates to worker a the procedure for dealing with the elevator 11 accident displayed on the screen (step S23).

[0032] In the above explanation, an example was shown where the data processing unit 24 was able to analyze how to deal with an accident involving the elevator 11. However, even if the data processing unit 24 cannot identify a course of action, the support worker, who is answering a call from worker a via the support worker terminal 200, can estimate how to deal with the accident and provide advice based on the elevator's status and operation logs.

[0033] After finishing the call with the support worker, worker A performs the repairs and parts replacements in step S16 based on the support worker's advice, and after completion, performs the operational check in step S17 to finish the work.

[0034] [Examples of display on each device] Next, we will explain the display examples on each device. Figure 5 shows an example of the input screen used by worker a when performing maintenance work on the elevator 11 using the maintenance work terminal 100. As shown in Figure 5, input buttons for letters (alphabet) and numbers are displayed on the left side of the screen, and buttons to assist with input such as Mode, Set, Reset, and OK are displayed on the right side of the screen. In addition, the display area for the entered letters and numbers is shown at the top of the screen. Operator A inputs codes indicating the operation status into the maintenance terminal 100 on this input screen. The operation log entered on the screen shown in Figure 5 is sent to the support center 20, as explained in step S22 of the flowchart in Figure 4.

[0035] Figure 6 shows an example of the screen displayed on the display unit 194 of the call terminal 190 for making a call to the support center 20, which is shown in step S23 of the flowchart in Figure 4. The screen shown in Figure 6 displays the text "Contact the Technical Support Center," along with OK and Cancel buttons. When worker a touches the OK button, a call is made to the support center 20 using the communication terminal 190. This call-making screen may also be displayed on the maintenance work terminal 100.

[0036] Figure 7 shows an example of the screen displayed on the support terminal 200 when a call is made to the support center 20 using the communication terminal 190. As shown in Figure 7, the support terminal 200 displays the worker's name, work site, work details, application program used, operation history information, communication history information, etc. Although not shown in Figure 7, if the data processing unit 24 analyzes the data and determines the cause of the failure or the name of the replacement part, this information may also be displayed on the same screen.

[0037] [Effects of this embodiment] As explained above, in this example, if worker a performing maintenance work on the elevator 11 cannot determine the cause of the malfunction using the maintenance work terminal 100, work-related information such as operation logs is automatically sent to the support center 20, and worker a can make a call to the support center 20 using the communication terminal 190. Upon receiving the call, the support center 20 automatically connects the call to a rear support terminal 200 suitable for assisting the elevator 11 being worked on, and support for the work is provided through a call from the rear support terminal 200. In this case, the work-related information and analysis results from the support terminal 200, which were sent immediately before the call, are displayed, allowing the support staff to understand the current working status of the elevator 11 and provide appropriate support to worker a.

[0038] Therefore, as in the past, the support center 20 no longer needs to select the appropriate support person from the phone call received from worker a. Worker a will be automatically connected to the appropriate support person and can receive advice quickly. In addition, the support person terminal 200 displays work-related information transmitted immediately before the call and the results of its analysis. As a result, the support person terminal 200 no longer needs to search for the status of the elevator being used by the worker, and support can be provided quickly by the support person.

[0039] Furthermore, in this example system, as shown in step S15 of the flowchart in Figure 4, the processing unit 112 of the maintenance work terminal 100 sends the work schedule and log to the support center 20 even if the cause of the elevator failure cannot be identified by executing the application program. This allows the support worker terminal 200 to determine whether there are any problems with the work. As a result, the support worker can provide appropriate support while observing the actual work performed by worker a. For example, the support worker can also look at the operation log to determine whether there are any errors in the operating procedure.

[0040] Furthermore, in this example system, as shown in Figure 6, after sending the work schedule and log to the support center 20, a button to call the support center 20 is displayed on the display unit 194, and by selecting the displayed button, a call to the support center 20 is made. As a result, making a call to the support center 20 can be easily done through screen operation, significantly reducing the burden on the worker.

[0041] Furthermore, in the system of this example, the support center 20 can identify worker a by identifying the telephone number of the calling terminal 190 or the maintenance work terminal 100 (hereinafter referred to as the "calling terminal") when a call is made from the calling terminal. As a result, the work schedule and log transmitted from the identified worker a's calling terminal can be retrieved from the storage unit 22 and displayed on the selected support terminal 200. This allows the support worker operating the support terminal 200 to immediately determine the status of the elevator 11, etc., enabling rapid support.

[0042] [Differentiation] The embodiments described above are detailed explanations provided to facilitate understanding of the present invention and are not necessarily limited to those comprising all the described configurations. Furthermore, the configurations and processes described in the above embodiments can be modified or altered in various ways.

[0043] For example, in the above-described embodiment, worker a is provided with a maintenance work terminal 100 and a communication terminal 190. However, the maintenance work terminal 100 may also be equipped with a communication function so that it can directly communicate with the support center 20. Furthermore, in the above-described embodiment, a call button is displayed on the communication terminal 190 following data transmission from the maintenance work terminal 100. However, the call may be initiated manually by the operator from either the communication terminal 190 or the maintenance work terminal 100. Conversely, the communication terminal 190 may be configured to initiate a call automatically without displaying such a call button.

[0044] Furthermore, data transmission from the maintenance terminal 100 is performed only when the cause of the failure cannot be identified by executing the application program within the maintenance terminal 100. Alternatively, data transmission from the maintenance terminal 100 may be performed automatically when a situation different from normal maintenance work is detected, such as when the time elapsed since the start of work exceeds a standard work time or when some kind of trouble is detected.

[0045] Furthermore, in the configuration shown in Figure 1, the maintenance work terminal 100 has a built-in application program that performs the processing in this example. However, it is also possible to modify a program implemented in an existing maintenance work terminal to perform the same processing. In this case, the program may be stored on an external memory, IC card, SD card, optical disc, or other recording medium and then transferred. Furthermore, instead of performing the processing in this example using an application program, it could also be implemented using dedicated hardware such as an FPGA (Field Programmable Gate Array) or ASIC (Application Specific Integrated Circuit).

[0046] Furthermore, in the configuration diagram shown in Figure 2, only control lines and information lines deemed necessary for explanation are shown, and not all control lines and information lines are necessarily shown in the actual product. In reality, it can be assumed that almost all components are interconnected. Also, in the flowchart shown in Figure 4, the processing order can be changed, or multiple processes can be executed simultaneously, as long as the processing result is the same.
