Description

[Technical field]

[0001] The present invention relates to an elevator maintenance and inspection work support system, an elevator maintenance and inspection work support method, and a program. [Background technology]

[0002] When performing maintenance and inspection work on elevators and other lifts, workers carry maintenance terminals equipped with communication functions so that they can notify a monitoring center of the start and end of work, etc. Depending on the progress of the work, the workers may also use the maintenance terminals to contact the monitoring center, etc., to receive support.

[0003] The maintenance terminal is a wireless telephone that communicates with other terminals using public wireless telephone lines, etc. For this reason, the maintenance terminal receives calls from customers, other maintenance workers, etc. at all times. For example, a worker may work in a place where safety must be ensured, such as on top of an elevator car or in a pit, and even while working in such a place, there is a possibility that the maintenance terminal carried by the worker may receive calls. It is not desirable for the maintenance terminal carried by the worker to receive calls while working in such a place where safety must be ensured. Also, from the viewpoint of work efficiency, it is not desirable for the maintenance terminal to receive calls while working, depending on the work content.

[0004] Patent Document 1 describes a technology that changes the forced answering of a call depending on the status of the caller and the callee when the caller makes a call and the callee is unable to receive the call. Patent Document 1 describes statuses such as conversation, waiting, and message. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 10-75299 Summary of the Invention [Problem to be solved by the invention]

[0006] In the case of the technology described in Patent Document 1, since incoming calls are simply controlled according to the status of the calling party and the called party, there is a problem in that sufficient consideration is not given to ensuring the safety of the worker on the called party or to preventing a decrease in work efficiency. For example, if the called party's status indicates that it is possible to receive (talk), the call will be received unless the worker himself changes the mode of the terminal device to reject the call or leave a message.

[0007] In this way, in maintenance work on elevators and other equipment, depending on the type of work and the location of the work, there are many cases where making phone calls is not desirable from the viewpoint of work efficiency and safety. However, in the past, calls were received on the maintenance terminal unless the worker himself changed the terminal mode. In this case, it would be best if the worker himself could change the mode of the terminal depending on the work content, but in reality there was a problem in that it was troublesome to change the mode of the terminal (telephone) for each work process.

[0008] For this reason, it was common to either set the phone to accept incoming calls even in situations where making calls was undesirable from the standpoint of work efficiency or safety, or to switch to a mode that rejected all incoming calls while working, but there was no detailed call control suitable for working on an elevator.

[0009] An object of the present invention is to provide an elevator maintenance and inspection work support system, an elevator maintenance and inspection work support method, and a program that can appropriately control incoming calls to a maintenance terminal during elevator maintenance and inspection work. [Means for solving the problem]

[0010] In order to solve the above problems, for example, the configurations described in the claims are adopted. The present application includes multiple means for solving the above-mentioned problems, and one example is an elevator maintenance and inspection work support system that is capable of receiving calls from outside and is equipped with a maintenance terminal carried by a worker performing elevator maintenance work. The maintenance terminal includes a transmission / reception unit that communicates with the elevator control device, an operation state identification unit that identifies the elevator operation state based on information obtained by the transmission / reception unit from the control device, a work position identification unit that identifies the work position based on information obtained by the transmission / reception unit from the control device, a memory unit that stores processing details when an incoming call is detected, and an incoming call processing determination unit that reads out the processing details stored in the memory unit based on the operation state identified by the operation state identification unit and the work position identified by the work position identification unit, and determines the processing to be performed when an incoming call is received. The system includes a work content identification unit which identifies the work content of the ongoing maintenance work, a transfer processing unit which transfers the incoming communication to another terminal when the processing to be performed upon an incoming call determined by the incoming call processing determination unit is an unanswerable call, and a transfer destination determination unit which determines the terminal to which the transfer processing unit will transfer the call based on the work content identified by the work content identification unit, and the incoming call processing determination unit determines the processing to be performed upon an incoming call taking the work content into consideration. Effect of the Invention

[0011] According to the present invention, it is possible to appropriately determine whether or not a call can be received at a maintenance terminal carried by a worker performing maintenance work, depending on the state of the elevator and the work position. Problems, configurations and effects other than those described above will become apparent from the following description of the embodiments. [Brief description of the drawings]

[0013] <First embodiment> An elevator maintenance work support system according to a first embodiment of the present invention will now be described with reference to Figs. 1 to 4.

[0014] [System Configuration] Fig. 1 shows a detailed configuration of an elevator maintenance work support system according to this embodiment. Here, we will assume that maintenance work is performed on an elevator as an example of an elevator. Note that maintenance work includes all work that workers do on elevators, such as inspection and repair.

[0015] The elevator maintenance work support system according to this embodiment includes a maintenance terminal 30 carried by a worker who performs maintenance work on the elevator 10. The maintenance terminal 30 is configured, for example, by a smartphone, which is an information processing terminal (computer). An application program for supporting maintenance work is installed in advance in the maintenance terminal 30. A worker can use this application program to register the start and end of work, and can receive support on work methods, etc. from the maintenance terminal 30 during work.

[0016] The maintenance terminal 30 also functions as a wireless telephone that can communicate with other terminals. The communications made by the maintenance terminal 30 include communications with the center that supports the maintenance work, communications with terminals of other workers, and communications with customers.

[0017] To explain the system configuration, the maintenance terminal 30 communicates with the control device 12 of the elevator 10 undergoing maintenance work. The elevator 10 is provided with a communication device 11 for communication between the maintenance terminal 30 and the control device 12. The elevator 10 communicates with a transmission / reception unit 311 provided in an input unit 31 of the maintenance terminal 30 via this communication device 11.

[0018] The maintenance terminal 30 can also communicate with other communication terminals 20 for making a call. That is, the call originating / receiving unit 312 included in the input unit 31 of the maintenance terminal 30 is connected to the call originating / receiving unit 21 of the other communication terminal 20 via a predetermined network N, and communicates with the other communication terminal 20 for making a call. The input unit 31 of the maintenance terminal 30 includes an incoming call detection unit 313, which detects an incoming call from the outside.

[0019] The maintenance terminal 30 also includes a state specifying unit 33, a storage unit 34, a determination unit 35, and an incoming call processing unit 36 ​​as a calculation unit 32 that executes various processes within the terminal itself. The state identifying unit 33 , the determining unit 35 , and the incoming call processing unit 36 ​​are processing units formed in the calculation unit 32 by an application program installed in the maintenance terminal 30 . That is, the calculation unit 32 is composed of a CPU (Central Processing Unit) and a memory, and these processing units are configured on the memory by executing an application program under the control of the CPU. Also, the incoming call detection unit 313 of the input unit 31 is a processing unit formed in the calculation unit 32 by executing an application program installed in the maintenance terminal 30.

[0020] The processing performed by the calculation unit 32 will be described in detail below. The state identification unit 33 of the calculation unit 32 has a driving state identification unit 331, an operation position identification unit 332, an operation content identification unit 333, and an application state management unit 334. The operating state identifying unit 331 identifies the operating state of the elevator based on information obtained through communication with the elevator 10 . The work position identification unit 332 identifies the position (work position) of the worker based on information obtained through communication with the elevator 10. Here, the work position of the worker is the position of the maintenance terminal 30. In the following description, the term "work position" refers to the worker's position estimated from the position of the maintenance terminal 30.

[0021] When the maintenance terminal 30 is connected to the control device 12 of the elevator 10, the elevator 10 stores the states of the switches and other devices installed on the elevator 10 in the memory of the control device 12. The elevator 10 then recognizes which part of the maintenance terminal 30 the control device 12 is connected to based on the ON / OFF (0 / 1) of a target bit in the memory of the control device 12. Similarly, the elevator 10 also determines the operating state based on the state of the installed switches.

[0022] For example, the elevator 10 determines the operating status of the elevator 10 and the position of the maintenance terminal 30 from a switch that turns ON / OFF when entering or exiting the pit, a switch that turns ON / OFF when getting on or off the car, and a load sensor inside the car when the elevator 10 is inside the car. Also, when the maintenance terminal 30 is connected to the control device 12 from the elevator hall (landing), the elevator 10 can identify the maintenance terminal 30, which is the work position, using information from the control device 12. The location information of the maintenance terminal 30 may be input by the worker himself / herself into the maintenance terminal 30. Also, the location information may be acquired by a method other than the methods described above.

[0023] The work content identification unit 333 identifies the work content of the worker. In this embodiment, the work content is identified from the usage status of the application program implemented in the maintenance terminal 30. Since each work is performed by using the target application program, the work content can be identified from the usage status of the application program. The usage status of the application program is acquired by the application status management unit 334.

[0024] The storage unit 34 includes an incoming call processing determination database 341. The storage unit 34 is configured with a main storage device such as a dynamic random access memory (DRAM) or a static random access memory (SRAM), and an auxiliary storage device such as a hard disk drive (HDD) or a flash memory. In the drawings, the database is abbreviated as DB. The incoming call processing determination database 341 stores the contents of the incoming call processing corresponding to the information of the state identification unit 33. Note that specific examples of the contents of the incoming call processing will be described later.

[0025] The determination unit 35 includes an incoming call processing determination unit 351 . The incoming call processing determination unit 351 refers to the information in the state specification unit 33 and the incoming call processing determination database 341 in the storage unit 34, and determines whether to answer the call or to reject the call. The incoming call processing unit 36 ​​includes a response processing unit 361 and an incoming call rejection processing unit 362 . The answering process unit 361 answers the incoming call when the result of the determination by the incoming call processing determination unit 351 is to answer the incoming call. For example, the incoming call processing unit 36 ​​performs incoming call processing such as rejecting the incoming call. When the result of the determination by the incoming call processing determination section 351 is to reject the incoming call, the incoming call rejection processing section 362 performs a process of rejecting the incoming call.

[0026] [System hardware configuration] FIG. 2 is a diagram showing an example of the hardware configuration of the system according to this embodiment. In the external communication terminal 20, the call originating / receiving unit 21 is connected to the control device 22, and outgoing and incoming call processing is performed by the call originating / receiving unit 21 under the control of the control device 22. The external communication terminal 20 also has a display 23, which displays information according to the state at the time of outgoing or incoming call. For example, when an incoming call is rejected at the destination during outgoing call, the display 23 displays a message indicating that the incoming call has been rejected. Furthermore, when a message is received by e-mail or the like from another terminal, the display 23 displays the message received by the communication terminal 20. Although not shown, the communication terminal 20 includes a speaker and a microphone for calls.

[0027] The maintenance terminal 30 includes a control device 40 having an input unit 31 and a calculation unit 32. To the control device 40, a transmitting / receiving unit 311, a transmitting / receiving unit 312, a speaker 391, a microphone 392, and a display 394 are connected. The speaker 391 and the microphone 392 are used during a call. The speaker 391 and the microphone 392 may be configured to be connected to the maintenance terminal 30 by wire or wirelessly.

[0028] The transmission / reception unit 311 of the maintenance terminal 30 wirelessly communicates with the communication device 11 of the elevator 10 and acquires information from the control device 12 of the elevator 10. For example, Bluetooth (registered trademark) is used for wireless communication between the transmission / reception unit 311 of the maintenance terminal 30 and the communication device 11 of the elevator 10. However, using Bluetooth for wireless communication is just one example, and other methods may be used.

[0029] [Processing flow when receiving a call] The flowchart in FIG. 3 shows the flow of processing performed by the maintenance terminal 30 when a call is received. First, the maintenance terminal 30 is wirelessly connected to the communication device 11 of the elevator 10 via the transmission / reception unit 311 (step S101). Then, an application program for supporting the maintenance work is started in the maintenance terminal 30 by an operation of the worker (step S102).

[0030] Next, the incoming call detection unit 313 of the maintenance terminal 30 judges whether or not there is an incoming call from the communication terminal 20 (step S103). If there is no incoming call in step S103 (NO in step S103), the maintenance terminal 30 waits until there is an incoming call. Then, if it is determined in step S103 that there is an incoming call (YES in step S103), the maintenance terminal 30 acquires information on the operating state of the elevator 10 and the worker's working position from the control device 12 of the elevator 10, and performs an operating state identification process and a working position identification process (step S104).

[0031] The operation state identification unit 331 of the maintenance terminal 30 then identifies the operation state of the elevator 10 from the information acquired in step S104 (step S105). The work position identification unit 332 then identifies the work position of the worker from the information acquired in step S104 (step S106). The identification of the work position of the worker here uses, for example, values ​​of the switches and load sensors of the elevator 10 already described.

[0032] Furthermore, the application status management unit 334 of the maintenance terminal 30 identifies the current work content from the progress of the work by the application program started in step S102 (step S107). Note that the work content can be identified not only from information from the application program, but also by a method of linking with the worker's schedule or a method of identifying the work content based on information input by the worker himself.

[0033] Next, the incoming call processing determination unit 351 determines whether or not a response is possible based on the results determined in steps 105 to 107 (step S108). In this step S108, if it is assumed that it is unsafe, such as when work is being done on the car or when the elevator is in operation, or if it is assumed that work will be affected if a communication abnormality occurs due to the incoming call, the incoming call is rejected, and otherwise it is assumed that a response is possible. A specific example of the determination in this embodiment will be described later with reference to FIG. 4.

[0034] If it is determined in step S108 that the call can be answered (YES in step S108), the response processing unit 361 of the maintenance terminal 30 performs response processing (step S109). The response processing in step S109 refers to processing for notifying the worker carrying the maintenance terminal 30 of the incoming call by, for example, ringing the maintenance terminal 30 or vibrating the maintenance terminal 30. Note that in the response processing in step S109, the worker can decide for himself or herself whether to answer the incoming call or not.

[0035] In addition, in step S108, if the call corresponds to the call rejection (NO in step S108), the call rejection processing unit 362 of the maintenance terminal 30 performs a process of rejecting the incoming call (step S110). The call rejection process in step S110 refers to a process of not notifying the worker of the incoming call by not sounding a ringtone or vibrating the phone.

[0036] [Example of rejecting an incoming call] FIG. 4 shows an example of combinations for rejecting incoming calls stored in the incoming call processing determination database 341 in this embodiment. Here, the call is either rejected or answered based on the work content based on the usage status of an application program that supports the maintenance work, the location of the worker, and the status of the elevator (elevator).

[0037] To explain the situations shown in Figure 4 in order, first, when an application program that is a tool for supporting maintenance work is not being used and the worker is in the elevator hall or car, the system answers the incoming call. Also, when an application program that is a tool for supporting maintenance work is not being used and the worker is in the car, the system rejects the incoming call. Then, when an application program that is a tool for supporting maintenance work is not being used and the worker is in the pit, if the elevator is operating, the system rejects the incoming call, and if the elevator is stopped, the system answers the call.

[0038] In addition, in a situation where the floor landing level of the car is being adjusted based on the application program, an incoming call is rejected when the worker is inside the car. In addition, when updating software to rewrite the program of the elevator control device (so-called ROM burning), incoming calls will be rejected if the worker is in the elevator hall, on the car, or in the pit (when the elevator is stopped).

[0039] In addition, while the elevator operation status is being read, if the worker is in the elevator hall, the call is answered. In addition, while the elevator operation status is being read, if the worker is in the pit, the call is rejected if the elevator is operating, and is answered if the elevator is stopped.

[0040] In addition, when registering the inspection position of the main rope of the elevator, if the worker is in the elevator hall or inside the car, the incoming call will be rejected. In addition, when a worker is working to measure the braking torque of a brake mechanism installed in an elevator, if the worker is in the elevator hall, incoming calls are rejected. Furthermore, when a worker is working to measure the braking distance of a brake mechanism installed in an elevator, incoming calls are rejected if the worker is in the elevator hall. In addition, the blank spaces in Figure 4 indicate that no work was being done in the corresponding location during each task.

[0041] As described above, according to this embodiment, by identifying the operating state and the working position, if an incoming call is detected and the worker is working in a place where it is not desirable to answer the incoming call, the maintenance terminal 30 can automatically reject the incoming call. This appropriately ensures the safety of the worker while working, and prevents the deterioration of work efficiency caused by answering an incoming call while working, leading to improved work efficiency. For example, as shown in Figure 4, incoming calls are rejected during precision work such as adjusting the landing level, inspecting the main rope, measuring braking torque, and measuring braking distance. This prevents work from having to be redone by answering a call, leading to improved work efficiency.

[0042] <Second embodiment> Next, an elevator maintenance work support system according to a second embodiment of the present invention will be described with reference to Figures 5 to 7. In Figures 5 to 7 illustrating this embodiment, parts corresponding to Figures 1 to 4 described in the first embodiment are given the same reference numerals, and duplicated explanations will be omitted. This embodiment is different from the first embodiment in that when an incoming call is rejected at the maintenance terminal 30, the incoming communication (telephone call) is transferred to another location.

[0043] [System Configuration] FIG. 5 shows a detailed configuration of the elevator maintenance work support system according to this embodiment. The elevator maintenance work support system of this embodiment differs from the first embodiment in that the determination unit 35 of the maintenance terminal 30 has a forwarding destination determination unit 352, and the incoming call processing unit 36 ​​of the maintenance terminal 30 has a forwarding processing unit 363. When the incoming call processing determination unit 351 determines that the incoming communication should be forwarded, the forwarding destination determination unit 352 determines whether to forward the call to the sales office, to a co-worker, or to a device other than the maintenance terminal 30, depending on the work content and work location at that time. The forwarding processor 363 performs forwarding processing of a communication (telephone call) that arrives at the forwarding destination determined by the forwarding destination determiner 352 . Other configurations of the maintenance terminal 30 are the same as those of the maintenance terminal 30 shown in FIGS.

[0044] [Processing flow when receiving a call] The flowchart in Fig. 6 shows the flow of processing at the time of an incoming call, which is performed by the maintenance terminal 30. In the flowchart in Fig. 6, steps S101 to S107 are the same as steps S101 to S107 described in the flowchart of the first embodiment (see Fig. 3).

[0045] Then, the incoming call processing determination unit 351 determines whether or not the call can be answered based on the results determined in steps 105 to 107 (step S108). The process in step S108 and the process in step S109 in the case where the call can be answered in step S108 (YES in step S108) are the same as those described in the flowchart of FIG. 3, and therefore description thereof will be omitted.

[0046] In this embodiment, if it is determined in step S108 whether or not a response is possible, and it is determined that the response is rejected (NO in step S108), the incoming call processing determination unit 351 of the maintenance terminal 30 determines whether or not the incoming communication (call) can be transferred (step S111). When the incoming call processing determination unit 351 determines whether or not the call can be transferred, it refers to information in the incoming call processing determination database 341. The configuration of the incoming call processing determination database 341 in this embodiment will be described later (FIG. 7).

[0047] If the call cannot be forwarded in step S111 (NO in step S111), the incoming call rejection processor 362 rejects the incoming call (step S110). Furthermore, if transfer is possible in step S111 (YES in step S111), the incoming call processing determination unit 351 determines whether or not the call can be transferred to a co-worker based on the identified work content (step S112). Whether or not the call can be transferred to a co-worker is also determined by referring to the information in the incoming call processing determination database 341. Note that if the current work is a work performed by one person, it is always determined in step S112 that the call cannot be transferred to a co-worker.

[0048] If it is determined in step S112 that the call cannot be forwarded to the co-worker (NO in step S112), the forwarding processor 363 forwards the call to the sales office (step S113). The forwarding destination may be registered in advance in the incoming call processing determination database 341, for example, or may be linked to contact book data held by the maintenance terminal 30 and forwarded to a location specified in the contact book data.

[0049] Although the forwarding destination is set to a sales office in this example, the forwarding destination is not limited to a sales office and can be changed to any location such as a head office or a monitoring center. If it is determined in step S112 that the call can be forwarded to the co-worker (YES in step S112), the forwarding processor 363 forwards the call to the co-worker (step S114). The telephone number of the co-worker is also registered in advance in the incoming call processing determination database 341, for example, or is linked to the contact book data held by the maintenance terminal 30, and the call is forwarded to a specified location in the contact book data.

[0050] [Example of call forwarding] FIG. 7 shows an example of combinations of incoming call forwarding stored in the incoming call processing determination database 341 in this embodiment.

[0051] To explain the situations shown in Figure 7 in order, first, when an application program that is a tool for supporting maintenance work is not being used and the worker is in the elevator hall or car, the system responds to the incoming call. Also, when an application program that is a tool for supporting maintenance work is not being used and the worker is in the car, the system rejects the incoming call and transfers the call to the service office. Also, when an application program that is a tool for supporting maintenance work is not being used and the worker is in the pit, if the elevator is operating, the system rejects the incoming call and transfers the call to the service office, and if the elevator is stopped, the system responds to the call.

[0052] In addition, in a situation where the floor landing level of the car is being adjusted based on the application program, if the worker is inside the car, the incoming call is rejected and transferred to the sales office. In addition, when rewriting the program of the elevator control device or updating the software, if the worker is in the elevator hall, on the car, or in the pit (when the elevator is stopped), the call will be rejected and transferred to the sales office. In addition, while the elevator operation status is being read, the system responds to incoming calls if the worker is in the elevator hall. In addition, while the elevator operation status is being read, if the worker is in the pit, the system rejects incoming calls while the elevator is operating and transfers them to the service office, and responds to calls while the elevator is stopped.

[0053] In addition, when registering the inspection position of the main rope of an elevator, if the worker is in the elevator hall, the call is rejected and transferred to a co-worker, and if the worker is in the elevator car, the call is rejected and transferred to the sales office. In addition, when a worker is working to measure the braking torque of a brake mechanism installed in an elevator, if the worker is in the elevator hall, the call is rejected and transferred to a co-worker.

[0054] Furthermore, when a worker is working to measure the braking distance of a brake mechanism installed in an elevator, if the worker is in the elevator hall, the call is rejected and transferred to the sales office. In addition, the blank spaces in Figure 7 indicate that no work was being done in the corresponding location during each task. In Figure 7, the case of transferring to a co-worker corresponds to a case where the corresponding task is performed by one person and work efficiency will not decrease if another co-worker answers the call, and the case of transferring to a sales office corresponds to a case where the corresponding task is performed by two people and it is not desirable for both people to answer the call.

[0055] As described above, according to this embodiment, in addition to the effects described in the first embodiment, it is determined whether a call can be transferred depending on the work content. Therefore, in a situation where a quick response is required such as an emergency and the recipient is in a situation where he / she cannot respond, the caller can quickly convey the requirements to the relevant parties. In particular, since it is automatically determined whether the transfer destination is to a co-worker or to an external party such as a sales office depending on the work content, it becomes possible to perform an appropriate transfer process depending on the work content.

[0056] <Third embodiment> Next, an elevator maintenance work support system according to a third embodiment of the present invention will be described with reference to Figures 8 to 11. In Figures 8 to 11 which explain this embodiment, the same reference numerals are used for the parts corresponding to Figures 1 to 7 which are explained in the first and second embodiments, and duplicate explanations will be omitted. In this embodiment, when an incoming call is rejected at the maintenance terminal 30, the forwarding process described in the second embodiment is performed, and when an incoming call is rejected or forwarded, notification is given to the terminals of the caller and the callee, which is different from the second embodiment.

[0057] [System Configuration] FIG. 8 shows a detailed configuration of the elevator maintenance work support system according to this embodiment. The elevator maintenance work support system according to this embodiment differs from the second embodiment in that the determination unit 35 of the maintenance terminal 30 is equipped with a work completion time estimation unit 353, the maintenance terminal 30 is equipped with an output unit 37 provided with a device for performing output processing such as a display 394, and the external communication terminal 20 is equipped with a display 23.

[0058] The work completion time estimation unit 353 of the maintenance terminal 30 estimates the work completion time from the standard work time for each work content. The display 394 of the maintenance terminal 30 and the display 23 of the external communication terminal 20 have the configuration described in FIG. The display 394 of the maintenance terminal 30 performs output processing to notify the user of the incoming call. The display 23 of the external communication terminal 20 performs output processing of the notification transmitted from the maintenance terminal 30. Other configurations of the maintenance terminal 30 are the same as those of the maintenance terminal 30 shown in FIG.

[0059] [Processing flow when receiving a call] The flowchart in Fig. 9 shows the flow of processing at the time of an incoming call performed by the maintenance terminal 30. In the flowchart in Fig. 9, the same processing as steps S101 to S109 described in the flowchart in Fig. 3 of the first embodiment is performed from step S101 to step S109. Also, the same processing as steps S110 to S114 described in the flowchart in Fig. 6 of the second embodiment is performed from step S110 to step S114.

[0060] Then, if the call is rejected in step S110, if the call is transferred to a sales office in step S113, or if the call is transferred to a co-worker in step S114, the work completion time estimation unit 353 of the maintenance terminal 30 estimates the work completion time from the standard work time for each work content and the elapsed time from the start of the current work (step S115). For example, it is assumed that the software update shown in Fig. 7 requires an average work time of 30 minutes. Here, if the work content identification unit 333 identifies that a software update work is in progress at the time of detecting an incoming call, it is estimated that the work will end 30 minutes after the start of the work. Here, information on the progress information of the application may be obtained from the application state management unit 334, and the work end time estimation unit 353 may estimate a more accurate work end time.

[0061] Next, the response processing unit 361 of the maintenance terminal 30 pushes the work completion time estimation result estimated by the work completion time estimation unit 353 to the communication terminal 20, and displays it on the display of the communication terminal 20 (step S116). This push notification and display is assumed to be performed, for example, using a telephone application program installed in the communication terminal 20, but any method may be applied as long as it is a method that can notify a text message. For example, various methods can be applied, such as notification by an application program having a message chat function, or notification by a short message service provided by a telephone company. Also, the notification of the work completion time estimation result may be performed only when the call is rejected in step S110, and the notification may be omitted when the call is transferred in steps S113 and S114.

[0062] Next, the incoming call processing determination unit 351 determines whether or not a transition to a response-enabled state has been detected based on the information of the state identification unit 33 (step S117). If the transition to a response-enabled state has not been detected in step S117 (NO in step S117), the incoming call processing determination unit 351 waits until the response-enabled state is reached. Then, when the state transitions to a state in which a response is possible in step S117, the fact that there has been an incoming call is displayed on the display 394 by push notification (step S118). It is assumed that the display of this push notification is also performed using a call application program installed in the maintenance terminal 30, but any method may be applied as long as it is capable of notifying a text message.

[0063] [Example of terminal display] FIG. 10 shows an example of a display on the display 23 of the other terminal 20 in step S116 of FIG. Here, a case is shown in which a message 23a is displayed stating "XXX-XXX-XXX (telephone number) is currently being worked on. Work is expected to be completed around 14:40." FIG. 11 shows an example of a display on the display 394 of the maintenance terminal 30 in step S118 of FIG. Here, a case is shown in which a message 394a is displayed stating "A call was received from XXX-XXX-XXX (telephone number) at 14:13."

[0064] Note that, although an example of notifying the user that an incoming call has been received is shown here, different messages may be displayed, for example, after rejecting the incoming call in step S110, after transferring the call to the sales office in step S113, and after transferring the call to a co-worker in step S114. For example, after "You have received an incoming call...", a message may be added that provides details about each call, such as "The call has been rejected," "The call has been forwarded to a sales office," or "The call has been forwarded to Mr. / Ms. XX."

[0065] In addition, the notification of the estimated work completion time shown in Figure 10 indicates the time when one unit of work is completed, but the time when the entire work on one elevator will be completed may be notified, and the call history display shown in Figure 11 may be displayed after the entire work on one elevator is completed.

[0066] As described above, according to this embodiment, in addition to the effects described in the first and second embodiments, when the called party is unable to respond, the caller can know when to call back. Also, the called party can receive the call in a safe situation or in a manner that does not interfere with work.

[0067] [Variations] The present invention is not limited to the above-described embodiment, but includes various modifications. For example, the above-described embodiment has been described in detail to easily explain the present invention, and is not necessarily limited to those including all of the configurations described. It is also possible to replace a part of the configuration of one embodiment with the configuration of another embodiment, and it is also possible to add the configuration of another embodiment to the configuration of one embodiment. It is also possible to add, delete, or replace a part of the configuration of each embodiment with another configuration.

[0068] For example, in each embodiment, the maintenance terminal 30 is provided with the state specifying unit 33, but the control device 12 of the elevator 10 may specify the state, and the maintenance terminal 30 may acquire the specified state. Alternatively, when an application program for supporting maintenance and inspection work implemented in the maintenance terminal 30 is executed while communicating with an external server, the maintenance terminal 30 may acquire the state from the server. Furthermore, in each embodiment, an elevator is used as an example of a lifting machine, but the present invention can also be applied to maintenance and inspection of other lifting machines such as escalators.

[0069] In addition, in the configuration diagrams shown in Figures 1 and 2, only control lines and information lines that are considered necessary for explanation are shown, and not all control lines and information lines in the product are necessarily shown. In reality, it can be considered that almost all components are connected to each other. Furthermore, the process flow shown in the flowchart in FIG. 3 is also one example, and as long as the process result is the same, the order of some processes may be changed or multiple processes may be executed simultaneously.

[0070] Moreover, the display examples shown in FIG. 10 and FIG. 11 are also preferred examples, and the present invention is not limited to these examples. Furthermore, when the system described in this embodiment is configured with an information processing device such as a computer, the programs that realize each processing function may be prepared in non-volatile storage or memory within the computer device, or may be stored on a recording medium such as an external memory, an IC card, an SD card, or an optical disk, and then transferred.
