Have been described.

JP 2011-1156 A

  By the way, in the case described above, what is transmitted by the monitoring device provided on the elevator side to the monitoring center device when a disaster occurs is basically abnormality information based on an abnormality detected by a seismometer or the like or a control device. However, when a disaster actually occurs, an abnormality that cannot be detected by the device, such as breakage of the vision glass of the landing door, may occur. When such an abnormality occurs, the maintenance staff dispatched in accordance with the content of the abnormality determines that the elevator cannot be restarted while the operation of the seismometer or the like is restored. Thus, when it is determined that the elevator cannot be restarted, the maintenance staff must report the reason to the monitoring center via a telephone or a portable terminal device. Also in the above-mentioned patent literature, as a result of investigating the property for disaster recovery, when it is determined that recovery is difficult at present, a call is made from the mobile terminal to the maintenance service management center, and the reason for recovery difficulty is notified. It is described. However, even if you try to report to the monitoring center via phone or mobile terminal device, it will prevent the system from going down due to the concentration of a large number of phones in a situation where a wide-area disaster such as a major earthquake or storm and flood has occurred. Because of so-called congestion regulation, there is a possibility that the telephone or mobile terminal device cannot be connected to the monitoring center and cannot be notified.

  In such a situation, the maintenance staff needs to quickly recover other damaged elevators, so he gives up reporting to the monitoring center and goes to the next site. As a result, the monitoring center cannot grasp the reason for the elevator malfunction. In such a case, even if a customer requests an early elevator operation or inquiries about non-operational details, the monitoring center responder cannot answer, and the maintenance staff cannot know whether the site has already been confirmed. In order to confirm the status of the elevator that was inquired, another maintenance staff had to be instructed to restart, and there was a problem that work efficiency was significantly reduced. In addition, in the above-mentioned patent document, the manager or the supervisor of the monitoring device installed in the management room recognizes the abnormality directly without receiving an abnormality report from the elevator control panel, and includes the property identification data. Although it is described that disaster situation data may be transmitted to the maintenance service management center, this is information from the person who manages the building, and is specialized in the elevator that is the subject of the present invention. The timing and purpose of the report from the local maintenance personnel with knowledge is different.

The monitoring device makes a notification to the monitoring center device via the public telephone line network.

  In the present invention configured as described above, when a maintenance worker inspects the elevator in response to the occurrence of a disaster such as an earthquake or a request for dispatch, when it is determined that re-operation is not possible, a property damage switch is turned on. In response to the turning on of the property damage switch, the monitoring device notifies the monitoring center device via the public telephone line network. In this way, even if the maintenance staff does not report to the monitoring center by telephone or mobile terminal device, the inspection is performed, and as a result, the monitoring center device is notified that it has been determined that re-operation is impossible. The status can be reliably grasped on the monitoring center side.

  Further, the present invention provides a light property loss switch that is input when it is determined that the property loss switch can be restarted by replacing parts, and a heavy property loss switch that is input when it is determined that repair work is necessary. It is characterized by having at least.

  In the present invention configured as above, when it is determined that the maintenance staff cannot restart the operation, if it is determined that the operation can be restarted by replacing the parts, the light property loss switch is turned on, while the repair work is required.

It is a schematic block diagram which shows one Example of the remote monitoring apparatus of the elevator of this invention. It is a flowchart which shows the process sequence of the remote monitoring apparatus in a present Example.

  Embodiments of a remote monitoring apparatus for an elevator according to the present invention will be described below with reference to the drawings.

  As shown in FIG. 1, the elevator according to the present embodiment has a car 1 and a counterweight 3 connected via a main rope, the main rope 2 is wound around a traction machine 4, and a control device 5 A motor (not shown) directly connected to the traction machine 4 is controlled to raise and lower the car 1. A seismometer 6 for detecting an earthquake is installed at the lower part of the hoistway.

  In the car 1, an in-car operation panel 7 is installed. In the in-car operation panel 7, a destination floor button 7e for registering the destination floor of the car 1 and a door for the car 1 are opened and closed. An open / close button 7f is arranged. In addition, a switch box 7a is provided at the lower part of the in-car operation panel 7 and is normally locked and provided with switches for maintenance personnel to perform various operations of the elevator. A stop switch 7c that is turned on when the car 1 is stopped, a maintenance switch 7d that places the car 1 in a low-speed operation during the maintenance work of the car 1, and a maintenance staff that has caused damage to the elevator that cannot be operated A material loss switch 7b is provided which is inserted using a key when the determination is made. When the property damage switch 7b is turned on, the car 1 cannot be operated in the same manner as when the stop switch 7c is operated.

  An operation signal of each switch installed in the car operation panel 7 and a pressing signal of each button are input to the control device 5, and the control device 5 performs control according to these various signals on the elevator. Further, all the signals input to the control device 5 are transmitted to the monitoring device 8, and the monitoring device 8 determines an abnormality based on these signals. When an abnormality is detected, an abnormality report is sent to the monitoring center device 10 via the public telephone line network 9.

  The processing device 10b of the monitoring center device 10 is connected to a database 10d that identifies the elevator based on the abnormality report received by the communication device 10a. The database 10d stores building information, elevator information, and the like of the building where the maintenance contracted elevator is installed. Accordingly, when receiving the abnormality report, the processing device 10b transmits the building information, the elevator information, and the received abnormality notification content to the display device 11a of the sales office 11 that has jurisdiction over the specified elevator.

  The sales office 11 is provided with a display device 11a, and an administrator of the sales office 11 confirms the display content of the display device 11a and asks the nearest maintenance staff or a maintenance staff standing by at the sales office 11. Instruct the dispatch to check the elevator that reported the abnormality.

  In the present embodiment, when an earthquake occurs, the control device 5 makes the car 1 stop in a state where passengers cannot use it on the nearest floor based on the input of the seismometer operation signal of the seismometer 6, and the monitoring device. 8 notifies the monitoring center device 10 of an earthquake in response to a received signal from the control device 5, and notifies that the car 1 has been stopped due to the earthquake.

  The processing device 10b of the monitoring center device 10 reads information from the database 10d based on the earthquake notification received by the communication device 10a, and displays the communication device 11c on the display device 11a of the sales office 11 having jurisdiction over the elevator that has received the earthquake notification. Send building information, elevator information, and earthquake notifications.

  The manager of the sales office 11 confirms the display content of the display device 11a, and instructs the nearest maintenance staff or maintenance staff standing by at the sales office 11 to dispatch to the elevator stopped by the earthquake. . In addition, since earthquakes affect a large number of elevators in a wide area, each maintenance staff is regularly trained to respond to earthquakes and is familiar with the addresses and patrol orders of priority responding customers such as hospitals. Therefore, once it is known that an earthquake has occurred, the elevators that have stopped due to the earthquake are restored in accordance with a predetermined traveling sequence without any instructions from the administrator.

  In an elevator stopped due to an earthquake, a display device (not shown) in which a position indicator lamp indicating the position of the car 1 is installed is turned off. In this case, the maintenance person who restores the elevator stopped by the earthquake first checks the position of the car 1, enters the car 1, turns on the maintenance switch 7d, moves the car 1 up and down at low speed, Check the state of the hall, riding comfort while driving, and any abnormalities. At this time, if there is no hindrance to the landing state or running state and there is no abnormal noise, it is determined that there is no hindrance to normal operation, the seismometer 6 is restored, and normal operation that can be used by the user is set for maintenance. The worker goes to the restoration of the next elevator. When the setting signal for the restoration of the seismometer 6 and the normal operation is input, the monitoring device 8 transmits an earthquake restoration signal to the monitoring center device 10. With this earthquake recovery signal, the manager recognizes that the earthquake recovery process for the elevator has been completed.

  On the other hand, when an abnormality is confirmed by maintenance personnel, for example, if it is recognized that the vision glass of the landing door is broken or an abnormal noise is generated, it is determined that the car 1 is in trouble, and an object is held by the key that it possesses. The loss switch 7b is turned on. At this time, it is judged whether the contents of damage can be dealt with by exchanging parts like glass exchange, or whether repair work is necessary like removing the counterweight 3, and if repair work is necessary, The stop switch 7c is turned on together.

  In response to the input of the closing signal of the property damage switch 7b, the monitoring device 8 also transmits the closing state signal of the stop switch 7c to the monitoring center device 10 as a property damage switch notification. With this property damage switch notification, the manager can use either the parts replacement or the repair work in order to use the elevator based on the fact that the elevator is not normally used and the stop switch 7c signal transmitted at the same time. Can be determined. Therefore, when there is an inquiry from an elevator customer, it is possible to answer that the site has been confirmed and that parts replacement or refurbishment work is necessary to use the elevator. In addition, since the elevator travel is stopped by the insertion of the property damage switch 7b, and the property damage switch notification is also performed with high importance, in order to prevent unnecessary notification from being made due to an erroneous operation or the like. After the earthquake is detected by the seismometer 6, the property damage switch 7b is set to be effective within a predetermined time.

  Next, specific processing when an earthquake occurs will be described based on the flowchart of FIG. In FIG. 2, the process performed by the maintenance staff is assigned a procedure number to S, the process of the monitoring device 8 is assigned a process number to T, and the process of the monitoring center device 10 is assigned a procedure number to U. Will be described.

  First, the operation of the seismometer 6 is constantly confirmed in the procedure T1 of the monitoring device 8. When an earthquake of a predetermined seismic intensity or more occurs and the seismometer 6 is activated, the elevator is stopped and the seismometer operation report is issued as procedure T2. Is transmitted to the monitoring center device 10.

  The processing device 10b of the monitoring center device 10 confirms whether or not the communication device 10a has received the seismometer operation report as the procedure U1, and when the seismometer operation report is received, it is stored in the seismometer operation report and the database. The building information and the elevator information are transmitted to the display device 11a of the sales office 11 having jurisdiction over the elevator through the transmission device 10c.

  The display device 11a of the sales office 11 displays the elevator building information and the elevator information for which the seismometer operation report has been issued, and the manager instructs the maintenance staff in charge to respond to the site.

  The maintenance staff who confirms the state of the elevator in accordance with the dispatching instruction or the predetermined order of patrol at the time of the earthquake ends the on-site confirmation if the elevator is not stopped in step S1. After this, if it is during an earthquake, the maintenance staff goes to confirm the next elevator in the patrol order.

  On the other hand, when the elevator is stopped in step S1 (when it is instructed to be dispatched in step U2, it is inevitably stopped), the elevator is inspected as step S2. As a result of this inspection, if there is no damage or abnormal noise and there is no problem for the user to use the elevator, the seismometer 6 is restored as step S6. However, if there is a problem in operating the elevator, it is determined in step S3 whether it can be restored by parts replacement. If it is determined that repair work is necessary, the stop switch 7c is turned on in step S4. In this state, the property damage switch 7b is also turned on as step S5. On the other hand, when it is determined that the recovery is possible by parts replacement, the stop switch 7c is not turned on, and only the property damage switch 7b is turned on as step S5. Next, in step S6, the maintenance staff restores the seismometer 6 and ends the site confirmation of the elevator. After this, the maintenance staff goes to the next elevator according to the patrol order.

  When the monitoring device 8 that has performed the procedure T2 confirms whether or not a predetermined time has elapsed from the operation of the seismometer 6 as the procedure T3, and detects that the property damage switch 7b is turned on as the procedure T4 within the predetermined time. As a procedure T5, a property switch input notification is transmitted to the monitoring center device 10. At this time, the stop switch 7c is turned on together. Next, in step T6, the restoration of the seismometer 6 is confirmed, and at the time of restoration confirmation, a seismometer restoration notification is transmitted to the monitoring center apparatus 10 as step T7.

  As the procedure U3, the monitoring center apparatus 10 that has performed the procedure U2 confirms whether or not the communication device 10a has received the property switch input notification. If the property switch input notification is received, the processing device 10b From the notification and the data stored in the database, the building information, the elevator information, and the property switch input notification are transmitted to the display device 11a of the sales office 11 having jurisdiction over the elevator. In response to this, the display device 11a displays the sent information.

  Also, as procedure U5, it is confirmed whether or not the earthquake recovery notification is received by the communication device 10a, and if there is an earthquake recovery notification received, the processing device 10b obtains the building information from the earthquake recovery notification and the data stored in the database as procedure U6. The elevator information and the earthquake recovery notification are transmitted to the display device 11a of the sales office 11 having jurisdiction over the elevator. In response to this, the display device 11a displays the sent information.

  Through the processing described above, the manager of the sales office 11 in the jurisdiction after the earthquake occurred, the number of elevators checked by maintenance personnel on site, the number of unidentified elevators, and elevator items that were determined to be inoperable due to confirmation Make sure of the extent of the loss. And if there is an inquiry from an elevator customer, a brief explanation will be given on the implementation or non-implementation of on-site response, availability of operation, and damage status when operation is not possible.

  According to the present embodiment, it is provided with a property loss switch 7b that is provided on the building side and is turned on when the maintenance staff judges that re-operation is impossible, and the monitoring device 8 responds to the insertion of the property damage switch 7b by the public telephone. By notifying the monitoring center device 10 via the network 9, the maintenance staff himself / herself did not report to the monitoring center by telephone or mobile terminal device, and as a result, it was determined that re-operation was impossible. Since the fact is notified to the monitoring center device 10, the state of the elevator can be reliably grasped on the monitoring center side. As a result, it is possible to appropriately respond to inquiries from the customer to the monitoring center 10 and to avoid a situation in which maintenance personnel are dispatched unnecessarily.

  In addition, when it is determined that there is a problem with the traveling of the car 1 by checking the abnormality by the maintenance staff, when it is determined that the vehicle can be restarted by replacing the parts, the property damage switch 7b is turned on, and when it is determined that repair work is necessary, it is stopped. By turning on the property damage switch 7b together with the switch 7c, the monitoring center side can grasp the state of the elevator in more detail, so that the monitoring center side can take an appropriate action and promptly restart the elevator. Can be realized.

  Further, the property damage switch 7b is arranged in the lockable switch box 7a in the in-car operation panel 7 and is composed of a key switch operated by a key, so that the property damage switch 7b is turned on by mischief. Can be prevented.

  Furthermore, the monitoring device 8 notifies the monitoring center device 10 via the public telephone network 9 in response to the switch 7d and the stop switch 7c being turned on within a predetermined time after the earthquake is detected. By performing the above, it is possible to prevent the property damage switch 7d and the stop switch 7c from being turned on due to an erroneous operation or the like and making unnecessary notifications to the monitoring center device 10.

  In the above-described embodiment, the stop switch 7c, which is generally provided in the switch box 7a and is operated by the maintenance staff, has the role of a heavy material loss switch, and repair work is performed when the maintenance staff confirms the abnormality. When it is judged necessary, the material loss switch 7b is turned on together with the stop switch 7c. On the other hand, when it is judged that the operation can be restarted by replacing parts, only the material loss switch 7b is turned on. Alternatively, a light loss switch that is input when it is determined that re-operation is possible by replacing parts, and a heavy loss switch that is input when it is determined that repair work is necessary may be separately provided. In addition, in this embodiment, the property damage is classified into two categories: a light property loss that can be restarted by replacing parts and a heavy property loss that requires renovation work. The present invention is not limited to this, and the level of property damage may be further subdivided, and a switch for reporting the level of each property loss may be provided so that more detailed information can be grasped by the monitoring center. Further, the property damage switch 7b is preferably a key switch that can be operated only by the owner of the key, but can also be constituted by a wave type switch similar to the stop switch 7c and the maintenance switch 7d.
