  The various status signals from each building facility transmitted to the remote monitoring device 22 include identification information of the building 4 where the building facility is provided and identification information of the building facility. When the abnormal signal is a signal for detecting that the emergency button 14 from the elevator car 8 is pressed, the building number for identifying the building 4, the elevator number for identifying the elevator car 8, and the emergency button 14 are pressed. A signal identification number indicating that the recording has been performed is included.

  The abnormality occurrence notification device 18 is provided between the various building facilities and the remote monitoring device 22. When an abnormal signal set in advance is output from the various building facilities, the abnormality notification device 18 acquires this and sends it to the remote monitoring device 22. This is an automatic alarm device having a function of automatically reporting the occurrence of an abnormality via the line 20.

  The dedicated wireless transmission / reception device 34 is an abnormality occurrence signal output unit having a function of outputting an abnormality occurrence signal under the control of the control device 50. Here, in order to communicate with the remote monitoring device 22 via the emergency dedicated wireless network 24, an abnormality occurrence signal is output using a wireless signal in a predetermined frequency band. As described above, the wireless signal can include various state signals from each building facility. These various state signals can be generated using an appropriate signal technique within a predetermined frequency band range. The dedicated wireless transmission / reception device 34 can be configured to include an antenna and a wireless transmission / reception circuit capable of transmitting / receiving a wireless signal within a predetermined wireless output intensity range in a predetermined frequency band.

  The dedicated wireless transmission / reception device 34 continues to transmit at a predetermined time interval after acquiring the reception notification from the remote monitoring device 22 after starting the output of the abnormality occurrence signal. As the predetermined time interval, for example, a 5-second interval, a 1-minute interval, or the like can be appropriately set.

  Since the dedicated wireless transmission / reception device 34 is for communicating with the remote monitoring device 22 via the emergency dedicated wireless network 24, the reception signal is received from the remote monitoring device 22 and an abnormality occurrence signal is sent to the remote monitoring device 22. The mission was fulfilled only after reaching. Therefore, it is necessary to continue the transmission of the abnormality occurrence signal until the reception notification is acquired from the remote monitoring device 22. Further, it is preferable to continue the transmission of the abnormality occurrence signal even when the reception notification is received from the remote monitoring device 22. By doing in this way, since the abnormality occurrence signal can also be directly received by the portable abnormality occurrence signal receiving device 42 of the maintenance engineer (FE) 40, it is possible to improve the responsiveness in dealing with the abnormal state.

  The abnormality occurrence signal receiving device 42 is a portable abnormality occurrence signal receiving means carried by a maintenance engineer (FE) 40 as described in FIG. The abnormality occurrence signal receiving device 42 displays a reception circuit that can receive the abnormality occurrence signal transmitted from the dedicated wireless transmission / reception device 34, a signal processing circuit that converts the received information into display data, and the converted display data. It includes a display and the like. As the abnormality occurrence signal receiving device 42, a radio receiver having a specification that is easy to handle for the maintenance engineer (FE) 40 and a specialized specification, or a mobile phone incorporating the specialized specification can be used.

In the example of FIG. 1, a building number, an elevator number, a signal identification number indicating that the emergency button 14 has been pressed, and the like are displayed. As a result, the maintenance engineer (FE) 40 knows that the user is locked in the elevator car, and immediately determines which elevator car in which building the elevator car 8 in which the user is locked is. Can be recognized.

  The backup power supply 16 shown in FIG. 1 is an emergency power supply (Urgent Power Supply) having a function of supplying emergency power to a component provided in the building 4 that constitutes the remote monitoring failure notification proxy system 10 in the event of a power failure. UPS). For example, it has a function of supplying emergency power to the dedicated wireless transceiver 34. As the backup power source 16, an appropriate power generation device, power storage device, or the like that can be automatically switched to a normal power source in the event of a power failure can be used.

  As described above, the control device 50 of FIG. 2 has a function of controlling the operation of each element constituting the remote monitoring failure notification proxy system 10 as a whole. As such a control device 50, an appropriate control circuit or a computer can be used. The control device 50 includes a switching control unit 52 and an output control unit 54.

  The switching control unit 52 has a function of switching so that an abnormality occurrence signal is output by the dedicated wireless transmission / reception device 34 which is an abnormality signal generation means when the abnormality occurrence notification device 18 cannot report an abnormality signal. The switching control unit 52 detects that the building equipment installed in the building 4 is abnormal and outputs an abnormality signal, and the abnormality occurrence reporting device 18 is in a state incapable of reporting to the remote monitoring device 22. A notification disabling detection module 58 that detects the event and outputs a notification disabling state signal, and a dedicated signal in place of the notification of the abnormality occurrence reporting device 18 when an abnormality signal is output and a notification disabling state signal is output.

  The output control unit 54 has a function of controlling the operation of the dedicated wireless transmission / reception device 34 that is an abnormal signal generating unit. The output control unit 54 acquires a reception notification from the remote monitoring device 22 and a reception notification from the abnormality occurrence signal receiving device 42 depending on the setting in order to control the operation of the dedicated wireless transmission / reception device 34. The module 66 includes an output stop processing module 68 that detects the operation of the output stop switch 38 and stops the output of the abnormality signal generating means when the abnormality processing by the maintenance engineer (FE) 40 is completed. As the output stop switch 38, for example, a switch that stops the operation of the dedicated wireless transmission / reception device 34 by a manual operation of a maintenance engineer (FE) 40 can be used.

  These functions can be realized by software. Specifically, it can be realized by executing a remote monitoring failure notification proxy processing program. Some of these functions may be realized by hardware.

  The operation of the above configuration, particularly each function of the control device 50, will be described in detail with reference to the flowchart of FIG. The flowchart of FIG. 3 is a flowchart showing a procedure for processing an abnormal state when an abnormality signal is output from the building equipment of the building 4 and a failure relating to the abnormality occurrence notification device 18 occurs. The procedure in FIG. 3 includes a procedure performed by a maintenance engineer (FE) 40 that has recognized the abnormality occurrence signal in addition to the procedure executed by the function of the control device 50. In FIG. 3, the procedure executed by the control device 50 is indicated by a solid line frame, and the procedure performed by the maintenance engineer (FE) 40 is indicated by a broken line frame. Each procedure indicated by a solid line frame corresponds to each processing procedure of the remote monitoring failure notification proxy processing program.

  In FIG. 3, when abnormality detection (S12) is performed from the normal state (S10), the procedure from S14 is performed. The abnormality detection process is executed by the function of the abnormality detection module 56 of the control device 50. Specifically, it is detected that the emergency button 14 provided on the elevator car 8 is operated by the user, and an abnormal signal is output.

  When an abnormality signal is output, a notification command for issuing an abnormality occurrence notification is issued (S14). Specifically, an acquisition of an abnormality signal is acquired, and an instruction for notifying the remote monitoring device 22 of the occurrence of an abnormality is transmitted to the abnormality notification device 18 via the public line 20.

  Then, it is determined whether or not reporting is impossible (S16). This process is executed by the function of the report failure detection module 58 of the control device 50. Inability to report means that the failure occurrence reporting device 18 itself has a failure, the public line 20 is cut off and the notification is interrupted there, the remote monitoring device 22 has a failure, and the public line 20 And the case where the notification of the occurrence of abnormality does not reach the remote monitoring device 22 within a predetermined time is included. Whether or not the notification is impossible is determined by requesting the remote monitoring device 22 to transmit a reception notification when the notification is received, and when the reception notification does not return within a predetermined time. Can be determined to be impossible. For example, 5 seconds or the like can be set as the predetermined time.

  If it is not determined that the notification is impossible, the remote monitoring device 22 normally receives a notification of the occurrence of an abnormality (S40). In this case, the remote monitoring device 22 analyzes the information included in the notification of the occurrence of the abnormality, and issues an instruction to rush to the maintenance site (FE) 40 to the site where the abnormality has occurred as necessary. The notification of the occurrence of abnormality includes various status signals of building equipment. Here, the building number, the elevator number, the signal identification number indicating that the emergency button 14 has been pressed, and the like that are included in the notification of the occurrence of an abnormality. It is possible to automatically issue an on-site express command to the maintenance engineer (FE) 40 based on such information.

  For example, the data of the field in charge of the maintenance engineer (FE) 40, the relationship data between the time zone and the location, etc. are sequentially stored in the database in advance, and collation with the information included in the notification of the occurrence of abnormality is predetermined. Follow the steps. As a result, the maintenance engineer (FE) 40 that can rush to the site where the abnormality occurred is specified, and information related to the site where the abnormality has occurred is automatically transmitted via the mobile phone carried by the maintenance engineer (FE) 40. You can do it. Therefore, the maintenance engineer (FE) 40 rushes to the site where the abnormality occurs. The procedure after the arrival at the site (S30) will be described later.

  If it is determined in S16 that the notification is impossible, the redialing of the notification to the remote monitoring device 22 via the public line 20 is continued, and further switching to the abnormality occurrence signal output is performed (S18). Then, an abnormality occurrence signal is output (S20). This step is executed by the function of the abnormality occurrence signal output module 60 of the control device 50. Specifically, a command to output an abnormality occurrence signal having a predetermined content is given to the dedicated wireless transmission / reception device 34 which is an abnormality occurrence signal output means.

  The dedicated wireless transmission / reception device 34 is connected to the emergency dedicated wireless network 24 and communicates with the remote monitoring device 22 by a wireless signal in a predetermined frequency band. And it is judged whether the remote monitoring apparatus 22 received (S22). This determination can have the same contents as the determination regarding the inability to report via the public line 20. That is, the remote monitoring device 22 is requested to transmit a reception notification when an abnormality occurrence signal is received, and when the reception notification returns within a predetermined time, the remote monitoring device 22 generates an abnormality. It can be determined that a signal has been received. For example, 5 seconds or the like can be set as the predetermined time.

  When the remote monitoring device 22 receives the abnormality occurrence signal, processing similar to that described in relation to S40 is performed.

  Then, even after obtaining the reception notification from the remote monitoring device 22, the dedicated wireless transmission / reception device 34 further continues to output the abnormality occurrence signal (S24). This continuation is intended to assist the maintenance engineer (FE) 40 in quickly responding to an abnormal state. As a result, a maintenance worker (FE) 40 who is in the vicinity of the site due to patrol or the like receives information from the dedicated wireless transmission / reception device 34 provided on the rooftop of the building 4 by the abnormality occurrence signal reception device 42 and displays it on the display. By visually recognizing, it is possible to easily detect the site where the abnormality has occurred (S28).

Accordingly, the maintenance worker (FE) 40 can quickly arrive at the site of the occurrence of the abnormality, in the above example, at the elevator car 8 where the user is confined (S30).
In S16, the remote monitoring device 22 receives a notification of the occurrence of an abnormality without determining that the notification is impossible, or in S22, the remote monitoring device 22 receives an abnormality occurrence signal via the emergency dedicated wireless network 24 (S40). Thus, even when a field express command is issued to the maintenance worker (FE) 40, the state of the process of S30 is entered.

  Then, the maintenance engineer (FE) 40 performs an abnormality recovery process (S32). In the above case, the user is rescued from the elevator car 8. When a series of abnormality recovery processing is completed, end processing is performed (S34). In the above example, maintenance check is performed to check whether or not an abnormality has occurred in the elevator, and the maintenance process is terminated when the elevator is normal. Then, the output stop switch 38 described in FIG. 2 is operated to stop the output of the abnormality occurrence signal output means (S36). This step is executed by the function of the output stop processing module 68 of the control device 50. In some cases, S36 may be performed immediately after the completion of the abnormality recovery process of S32, or S36 may be performed together with the arrival at the site of S30.

  The dedicated wireless transmission / reception device 34 may be set to stop transmission of the abnormality occurrence signal when the reception notification from the abnormality occurrence signal reception device 42 is acquired. This procedure is executed by the function of the reception notification acquisition module 66 of the control device 50. When such setting is performed and the output of the abnormality signal has already stopped before the maintenance worker (FE) 40 arrives at the site where the abnormality has occurred, the process of S36 for the dedicated wireless transceiver 34 is omitted. can do.

  Then, the report redialing of the abnormality occurrence reporting device 18 is stopped (S38). As a result, the processing of the abnormal state when the abnormality occurrence signal is output and the notification by the abnormality occurrence notification device 18 is impossible is completed.
