For example, the monitoring terminal 4 of the present embodiment monitors a large number of elevators installed in a plurality of areas, and is installed in a monitoring center or the like that is a building apart from the target elevator. A supervisor (operator) is resident in the monitoring center of this embodiment.

  The monitoring terminal 4 can be connected to the mobile terminal 5 via a communication system (second communication system) R2 different from the communication system R1. The communication system R2 is a communication system including, for example, a modem, the Internet, a router, and wireless communication. The wireless communication here is, for example, mobile phone communication. Thus, the remote monitoring unit 3 is connected to the monitoring terminal 4 via the communication system R1, and the monitoring terminal 4 can be connected to the portable terminal via the communication system R2. The portable terminal 5 of this embodiment can communicate with the remote monitoring unit 3 via the communication system R1 and the communication system R2.

  The storage unit 41 of the present embodiment stores a remote monitoring application 410 that is an application executed by the CPU 40. The remote monitoring application 410 is an application for remotely monitoring the elevator 2.

  The CPU 40 of the present embodiment receives information related to the state of the elevator 2 from the remote monitoring unit 3 by executing the remote monitoring application 410 stored in the storage unit 41 during normal remote monitoring. In addition, by executing the remote monitoring application 410, the monitoring terminal 4 displays, for example, input information on the display unit. Thereby, the monitoring person can monitor the operation state of the elevator 2 by the monitoring terminal 4.

  Further, the CPU 40 according to the present embodiment remotely operates the elevator 2 by executing the remote monitoring application 410 when receiving a remote operation command from a monitor during normal remote monitoring. That is, the monitoring person can perform the remote operation of the elevator 2 by executing the remote monitoring application 410 using the monitoring terminal 4. By this remote operation, for example, the car of the elevator 2 can be moved.

  Furthermore, when the CPU 40 according to the present embodiment receives information related to the state of the elevator 2 from the remote monitoring unit 3 when confirming the operation of the remote monitoring system, the CPU 40 does not execute the remote monitoring application 410 and receives the input elevator 2.

That is, when the operation of the remote monitoring system is confirmed, the information on the state of the elevator 2 output from the remote monitoring unit 3 passes (through) the monitoring terminal 4 and is output to the portable terminal 5.

  In addition, when the CPU 40 of this embodiment receives an instruction for remote operation of the elevator 2 from the technician's portable terminal 5 when confirming the operation of the remote monitoring system, the CPU 40 does not execute the remote monitoring application 410 but inputs the elevator 2 that has been input. Is output to the remote monitoring unit 3. That is, when the operation of the remote monitoring system is confirmed, information for remotely operating the elevator 2 output from the portable terminal 5 passes through the monitoring terminal 4 and is output to the remote monitoring unit 3.

  The portable terminal 5 includes a CPU 50 that executes a program, a storage unit 51 that stores a program executed by the CPU 50, a display unit, a speaker, and a microphone (not shown). The portable terminal 5 is, for example, a PDA (Personal Digital Assistant). The portable terminal 5 of this embodiment is operated by a technician when checking the operation of the remote monitoring system. Specifically, the portable terminal 5 is operated in a hands-free manner by a technician using voice or the like. When checking the operation of the remote monitoring system, this technician stays in the vicinity of the elevator 2 to be monitored remotely.

  The storage unit 51 of the present embodiment stores a remote operation application (second execution file) 510 that is a program executed by the CPU 50. In addition to the function of the remote monitoring application 410 of the monitoring terminal 4, the remote operation application 510 has a function of causing a pseudo trouble for the elevator 2 by remote operation.

  When the CPU 50 of the present embodiment receives an input of information related to the state of the elevator 2 from the remote monitoring unit 3 via the monitoring terminal 4, that is, via the communication systems R1 and R2, when confirming the operation of the remote monitoring system. Then, the remote operation application 510 stored in the storage unit 51 is executed, and information related to the state of the elevator 2 is displayed on the portable terminal 5. That is, the CPU 50 causes the portable terminal 5 to display information related to the state of the elevator 2 by executing the remote operation application 510.

  Further, the CPU 50 according to the present embodiment remotely operates the elevator 2 by executing the remote operation application 510 when receiving a remote operation command from a technician when confirming the operation of the remote monitoring system.

In this remote operation, in addition to the normal remote operation, for example, a pseudo trouble such as stopping the car at a position shifted from the landing with respect to the elevator 2 can be caused.

  Hereinafter, the flow of processing in the operation check system 1 will be described with reference to the flowchart of FIG.

  The technician starts communication of the portable terminal 5 around the elevator 2 to be remotely monitored (S01). At the start of this communication, for example, the portable terminal 5 outputs a signal to the effect that confirmation of the operation of the remote monitoring system starts to the CPU 40 of the monitoring terminal 4 via the communication system R2. In response to the input of this signal, the CPU 40 passes (through) the information on the state of the elevator 2 output from the remote monitoring unit 3 via the communication system R1 through the monitoring terminal 4 and carries the information via the communication system R2. Output to the terminal 5. At this time, as described above, the remote monitoring application 410 of the monitoring terminal 4 is not executed.

  The technician executes the remote operation application 510 (S02) and confirms the operation of the remote monitoring system (S03). The confirmation of the operation of the remote monitoring system here means that the communication between the elevator 2 and the monitoring terminal 4 with the communication system is appropriate, the monitoring terminal 4 from the information output unit 21 via the remote monitoring unit 3 and the communication system R1. This is performed by confirming that proper information is output and that the remote operation of the elevator 2 is appropriate. It should be noted that when any information output from the remote monitoring unit 3 to the monitoring terminal 4 via the communication system R1 and output from the monitoring terminal 4 to the mobile terminal 5 via the communication system R2 is displayed on the mobile terminal 5. Thus, the technician can confirm that the communication connection between the elevator 2 and the monitoring terminal 4 via the communication system R1 is appropriate. That is, if it can be confirmed that appropriate information is output from the elevator 2 to the portable terminal 5, it can be said that the communication connection between the elevator 2 and the monitoring terminal 4 via the communication system R1 is appropriate.

  For example, the technician confirms that the state of the elevator actually observed and the information on the state of the elevator 2 confirmed on the mobile terminal 5 match, thereby indicating that appropriate information is output to the monitoring terminal 4. Can be confirmed. For example, regarding the control microcomputer 210, the technician directly operates the elevator 2 to move the position of the car to confirm the actual position of the car, and also receives the “car position information” output from the control microcomputer 210. Confirm with. Regarding the interactive telephone 211, the technician moves into the car while holding the mobile terminal 5, speaks to the microphone of the mobile terminal 5 and confirms the sound output to the car interphone, and then talks to the car interphone. The sound output from the speaker of the portable terminal 5 is confirmed. Regarding the camera 212, the technician checks the actual state of the car and the captured image output from the camera 212 to the mobile terminal 5. Regarding the sound collector 213, the engineer confirms the sound around the actual car and the counterweight, and confirms the peripheral sound collected by the sound collector 213 on the portable terminal 5. Regarding the detection sensor 214, the technician moves from the outside of the car to the inside of the car, and checks the portable terminal 5 for information regarding the presence or absence of a person in the car output from the motion sensor. Regarding the power monitoring device 215, the engineer switches the power supply of the elevator 2 on and off, and checks the power status information output from the power monitoring device 215 on the portable terminal 5.

  Further, the technician can confirm that the remote operation of the elevator 2 is appropriate by executing the remote operation application 510 of the mobile terminal 5 to remotely operate the elevator 2. For example, the technician executes the remote operation application 510 of the portable terminal 5 to display a message on the display panel in the car and confirms that this message is displayed on the display panel in the car. The technician executes the remote operation application 510 of the mobile terminal 5 to move the car and confirm the actual movement of the car.

  Further, the technician can execute the remote operation application 510 to cause a pseudo trouble for the elevator 2 and confirm whether or not this trouble can be detected. For example, after the remote operation application 510 is executed, a trouble such as stopping the car at a position shifted from the landing is caused for the elevator 2, and then information corresponding to the trouble is output to the mobile terminal 5. Check.

  Thus, the technician can confirm the operation of the remote monitoring system.

  As described above, the mobile terminal 5 can confirm the operation of the elevator 2 by communicating with the remote monitoring unit 3 through the communication system R1 and the communication system R2, and by communicating with the monitoring terminal 4 through the communication system R2, It can also be confirmed whether or not the monitoring terminal 4 can receive the information of the elevator 2 from the remote monitoring unit 3 (that is, whether or not the remote monitoring unit 3 is connected to the communication system R1). Thereby, it is confirmed by one technician whether the remote monitoring system of the elevator 2 can be executed by the technician having the portable terminal 5 at the site (in the vicinity of the target elevator 2). Can do.

  Note that the operation confirmation system 1 of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention. For example, the configuration of another embodiment can be added to the configuration of a certain embodiment, and a part of the configuration of a certain embodiment can be replaced with the configuration of another embodiment. Furthermore, a part of the configuration of an embodiment can be deleted.

  For example, in the operation check system 1, the storage unit 51 of the mobile terminal 5 has the remote operation application 510, but the storage unit of the server may have such an application instead of the storage unit 51 of the mobile terminal 5. . Specifically, the operation confirmation system includes a server 6 as shown in FIG. The server 6 can be connected to the mobile terminal 5 via a communication system (fourth communication system) R4 different from the communication system R1 and the communication system R2. The communication system R4 is a communication system including, for example, a modem, the Internet, a router, and wireless communication. A part of the communication systems R2 and R4 (Internet, router, and wireless communication) is common.

  The server 6 includes a CPU 60 that executes a program and a storage unit 61 that stores a program executed by the CPU 60. The storage unit 61 of the server 6 includes a remote operation application (first execution file) 610. The server 6 of this embodiment is a cloud server.

  The storage unit 51 of the portable terminal 5 includes a browser 511 that can operate the remote operation application 610. Specifically, the browser 511 can execute the remote operation application 610, and by executing this, the mobile terminal 5 can display information on the state of the elevator 2 on the display unit.

  In such a configuration, since the server 6 has the remote operation application 610, the mobile terminal 5 does not need to have this application, and the memory capacity (capacity of the storage unit 51 and the like) of the mobile terminal 5 can be suppressed.

  Moreover, since the technician can visually confirm the information related to the state of the elevator 2 with the mobile terminal 5, it is easy to grasp the state of the elevator 2.

  The portable terminal 5 can communicate with the remote monitoring unit 3 via the communication system R1 and the communication system R2, but the remote monitoring unit 3 via a communication system (third communication system) R3 different from the communication systems R1 and R2. 3 CPUs 30 may be connectable.

  In this case, as shown in FIG. 4, for example, when the remote monitoring unit 3 and the telephone line of the communication system R1 are not yet connected, first, the portable terminal 5 and the remote monitoring unit 3 are connected via the communication system R3. It is also possible to confirm the operation of the remote monitoring unit without connecting the monitoring terminal 4 using the communication system R3. The communication system R3 is a communication system including P2P, other wired lines, or wireless lines.

  Even if the CPU 30 of the remote monitoring unit 3 and the portable terminal 5 can be connected via the communication system R3, the operation check system 1 includes the server 6 having the remote operation application 610 as shown in FIG. In addition, the mobile terminal 5 may have a browser 511.

  In such a configuration, the portable terminal 5 is connected to the remote monitoring unit 3 via the communication system R3, so that the elevator 2 is monitored by the portable terminal 5 regardless of whether the remote monitoring unit 3 is connected to the communication system R1. It is possible to confirm the operation of the remote monitoring system excluding the terminal 4. After confirming the operation, if the technician can confirm the information on the state of the elevator 2 output from the remote monitoring unit 3 via the communication systems R1 and R2 with the portable terminal 5, the operation confirmation of the remote monitoring system is performed. It ’s gone.

  The mobile terminal 5 can communicate with the remote monitoring unit 3 via the communication system R1 and the communication system R2. In addition, the mobile terminal 5 is connected to the telephone line of the communication system R1 so as to be communicable. It may be possible to communicate with the remote monitoring unit 3 without going through R2. In this case, since the portable terminal 5 can be connected to the CPU 30 of the remote monitoring unit 3 via a telephone line, it is confirmed whether or not the remote monitoring unit 3 is connected to the telephone line without going through the monitoring terminal 4. Can do.

  As an example of confirming whether or not the remote monitoring unit 3 is connected to a telephone line without going through the monitoring terminal 4, in the operation confirmation system 1, for example, an elevator different from the elevator 2 that is the object of operation confirmation There may be a case where the monitoring terminal 4 is connected via a telephone line and it has already been confirmed that this communication is possible. In this case, the telephone line connected to the remote monitoring unit 3 that monitors the target elevator 2 and the portable terminal 5 are connected, and the operation check of the communication system including the remote monitoring unit 3, the telephone line, and the portable terminal 5 is performed. By performing, it can confirm that communication via the telephone line with the target elevator 2 and the monitoring terminal 4 is possible.

  In the operation check system 1 of the above embodiment, the specific configuration of each communication system is not particularly limited as long as the mobile terminal 5 can communicate with the remote monitoring unit 3 via the communication systems R1 and R2. For example, the information output unit 21 of the above embodiment is connected to the CPU 30 of the remote monitoring unit 3 by P2P, but may instead be connected by the Internet using a wired line or wireless communication. In addition, a modem is interposed between the CPU 30 and the telephone line and between the telephone line and the monitoring terminal 4 in the communication system R1, but a DSU (Digital Service Unit) is interposed instead of the modem. May be.

  In the operation check system 1 of the above embodiment, information related to the state of the elevator 2 is displayed on the monitoring terminal 4 by the execution of the remote monitoring application 410, and this information is displayed on the portable terminal 5 by the execution of the remote operation application 510. If the monitoring terminal 4 or the portable terminal 5 has a speaker, the information may be output as a message as a voice instead of displaying this information. Moreover, the monitoring terminal 4 and the portable terminal 5 may perform both display of this information and audio output.

  Although the number of elevators 2 in the above embodiment is one, a plurality of elevators 2 may be provided. In this case, one remote monitoring unit 3 may monitor a plurality of elevators 2, or a plurality of remote monitoring units 3 may include a plurality of remote monitoring units 3 such that one remote monitoring unit 3 monitors one elevator 2.
