JP 2007-197203 A

  The conventional earthquake recovery operation device for elevators disclosed in Patent Document 1 causes a plurality of elevators to start earthquake recovery diagnosis operation sequentially by shifting the time one by one for a plurality of elevators. Recovery diagnosis operation will be performed. For this reason, when there is a high possibility that the elevator has become abnormal due to an earthquake, all the elevators were installed in the equipment and hoistways provided in the elevator car along with the earthquake restoration diagnosis operation. There is a risk of facilitating a failure of the device. In particular, if there is an abnormality in multiple elevators, if multiple elevators fail due to the earthquake recovery diagnosis operation of all elevators, it takes time to restore these elevators, and the elevator service There is a risk of impairing sex.

  The present invention has been made based on the actual situation of the prior art as described above, and an object thereof is to provide an earthquake recovery diagnosis operation apparatus for an elevator that can avoid a failure associated with an earthquake recovery diagnosis operation.

  In order to achieve the above object, the elevator earthquake recovery diagnosis operation device of the present invention causes each of a plurality of elevators to perform seismic control operation when there is a predetermined vibration or more during earthquake occurrence, and this seismic control operation. In the earthquake restoration diagnosis operation device for an elevator that performs operation control for detecting the presence or absence of an abnormality through the monitoring device and causing the earthquake restoration diagnosis operation through the monitoring device, the earthquake restoration diagnosis operation for the plurality of elevators Diagnostic operation setting means for setting the priority order of the elevators to be performed, and diagnosis for outputting a diagnostic operation start command for starting the earthquake recovery diagnosis operation of the plurality of elevators according to the priority order set by the diagnostic operation setting means An operation command means and the earthquake restoration diagnosis started in response to the diagnostic operation start command among the plurality of elevators Stops the earthquake recovery diagnosis operation of the specific elevator in which an abnormality is detected by driving, and outputs a diagnosis operation stop command to stop the start of the earthquake recovery diagnosis operation of the elevator having the lower priority than the specific elevator Diagnostic operation stopping means.

  The present invention configured as described above sets the priority order of elevators for causing earthquake restoration diagnosis operation to a plurality of elevators in order of elevators that are likely to be normal by the diagnostic operation setting means, and performs diagnostic operation commands according to this priority order. Since the earthquake restoration diagnosis operation is started by the means, an elevator having no abnormality can be quickly restored. When an abnormality in the elevator is detected by the earthquake restoration diagnosis operation started according to the priority set by the diagnosis operation setting means, the earthquake restoration diagnosis operation of the specific elevator in which this abnormality is detected is stopped by the diagnosis operation interruption means. Therefore, it is possible to avoid failure of the specific elevator by continuing the earthquake restoration diagnosis operation. In addition, the diagnosis operation stop means stops the start of earthquake recovery diagnosis operation of an elevator having a lower priority than the specific elevator, that is, an elevator that is more likely to be abnormal than the specific elevator. It can be avoided that the elevator breaks down. That is, according to the present invention, it is possible to avoid a failure associated with the earthquake restoration diagnosis operation.

  In the elevator earthquake recovery diagnosis operation device according to the present invention, in the invention, the diagnosis operation setting means indicates that each of the elevator cars in the plurality of elevators is running or stopped when an earthquake occurs. The priority order is set based on operation information and car position information indicating the position of each car when the operation is stopped by the seismic control operation.

  In the present invention configured as described above, the diagnostic operation setting means can detect two types of information, that is, the operation information of the car in each elevator at the time of the earthquake and the car position information of each car when the operation is stopped by the seismic control operation. By setting the above-mentioned priority order based on the elevator information, it is possible to reduce an error between the set priority order and the order that is unlikely to be abnormal in the actual elevator. Thereby, the reliability with respect to the earthquake restoration diagnosis driving | operation of an elevator can be improved.

  Further, in the elevator earthquake recovery diagnosis operation device according to the present invention, in the invention, the diagnosis operation setting means is more effective when the earthquake occurs than the elevator in which the car is traveling when the earthquake occurs among the plurality of elevators. Priority is given to the elevator in which the car is stopped, and the elevator in which the position of the car is lower in the elevator when the car is stopped by the seismic control operation among the elevators in which the car is traveling at the time of occurrence of an earthquake. Prioritize and prioritize the elevator with the lower position of the car in the elevator when the elevator is stopped by the seismic control operation among the elevators that are stopped when an earthquake occurs It is characterized by. If comprised in this way, a diagnostic driving | operation setting means can set the priority order rationally in order of an elevator with high possibility that there is no abnormality.

  The present invention relates to diagnostic operation setting means for setting priority order of elevators for performing earthquake recovery diagnosis operation for a plurality of elevators, and earthquake recovery diagnosis operation for a plurality of elevators according to the priority order set by the diagnostic operation setting means. Diagnostic operation command means for outputting a diagnostic operation start command for starting the operation. Therefore, since the earthquake restoration diagnosis operation is started by the diagnosis operation command means in the order of elevators in the priority order set by the diagnosis operation setting means, an elevator having no abnormality can be quickly restored and high serviceability can be ensured. it can.

  And this invention cancels the earthquake restoration diagnostic driving | operation of the specific elevator in which abnormality was detected by the earthquake restoration diagnostic driving | operation which started in response to the diagnostic driving | operation start command among several elevators, and a priority order is higher than a specific elevator. Diagnostic operation stop means for outputting a diagnosis operation stop command for stopping the start of the low-elevator earthquake recovery diagnosis operation is also provided. As a result, the specific elevator in which the abnormality is detected by the earthquake recovery diagnosis operation and the elevator that causes the earthquake recovery diagnosis operation after this specific elevator, that is, the elevator that is highly likely to be detected in the earthquake recovery diagnosis operation by the diagnosis operation stop means. Failures associated with the earthquake restoration diagnosis operation can be avoided, and the safety and serviceability of the elevator can be improved as compared with the conventional case.

It is a figure which shows the structure of one Embodiment of the earthquake recovery diagnostic driving | operation apparatus of the elevator which concerns on this invention. It is a flowchart which shows the operation | movement procedure of this embodiment.

The group management panel 14 includes an I / F circuit 15 and a control circuit 16, and performs group management control of these elevators 30 and 31. Further, the control panels 5 and 17 of the elevators 30 and 31 are respectively connected to the earthquake detector 11. This seismic detector 11 includes an I / F circuit 13 and a control circuit 12, and is installed in a hoistway (not shown) or in a machine room or the like, and a signal for notifying seismic information when a seismic intensity exceeding a predetermined seismic intensity is detected. Output to control panels 5 and 17, respectively.

  Further, the control panels 5 and 17 of the elevators 30 and 31 are respectively provided with I / F circuits 6 and 18 and control circuits 7 and 19. When the earthquake information signal is received from the earthquake detector 11, each elevator 30 and 31 is provided. , 31 is operated by seismic control and stopped.

  Similarly, each of the monitoring devices 8 and 20 of the elevators 30 and 31 includes I / F circuits 9 and 21 and control circuits 10 and 22, respectively. The I / F circuit 9 is provided in the elevator 30 when an earthquake occurs. Information of the elevator 30 such as operation information indicating that the car 1 is running or stopped, car position information indicating the position of the car 1, and confirmation information on the number of service floors of the elevator 30 is recorded. Similarly, the I / F circuit 21 includes operation information indicating that the car 26 in the elevator 31 at the time of the earthquake is running or stopped, car position information indicating the position of the car 26, and service of the elevator 31. Information of the elevator 31 such as confirmation information of the number of floors is recorded. The monitoring devices 8 and 20 are connected to each other. When the control panels 5 and 17 of the elevators 30 and 31 receive the earthquake information signal from the earthquake detector 11, the monitoring device 20 is connected to the I / F circuit 21. The recorded operation information and car position information of the car 26 in the elevator 31 are transmitted to the monitoring device 8.

  Further, the control circuit 10 of the monitoring device 8 sets the priority of the elevators 30 and 31 for causing the elevators 30 and 31 to perform the earthquake restoration diagnosis operation, and the priority set by the diagnosis operation setting means. And a diagnostic operation command means for outputting a diagnostic operation start command for starting the earthquake restoration diagnostic operation of the elevators 30 and 31 to the control panels 5 and 17.

  Further, the control circuit 10 of the monitoring device 8 stops the earthquake restoration diagnosis operation of the specific elevator in which the abnormality is detected by the earthquake restoration diagnosis operation started in response to the diagnosis operation start command of the elevators 30 and 31 and the specific elevator. Also included is a diagnostic operation stopping means for outputting a diagnostic operation stop command for stopping the start of the earthquake restoration diagnostic operation of an elevator having a lower priority than that of the elevator.

  The diagnostic operation setting means of the control circuit 10 of the monitoring device 8 includes, for example, operation information indicating that each of the cars 1 and 26 in the elevators 30 and 31 is running or stopped when an earthquake occurs, and seismic control operation. The above-mentioned priority order is set based on the car position information indicating the position of each of the cars 1 and 26 when stopped.

  Specifically, the diagnostic operation setting means of the control circuit 10 of the monitoring device 8 gives priority to the elevator in which the car is stopped when the earthquake occurs, over the elevator in which the car is traveling when the earthquake occurs. Priority is given to elevators that are lower in the elevator car position when the elevator is stopped due to seismic control operation among elevators that are in operation when the earthquake occurs, and seismic control operation of elevators that are stopped when the earthquake occurs The priority is set by giving priority to the elevator with the lower position of the car in the elevator when the vehicle is stopped.

  Hereinafter, the operation when the elevators 30 and 31 that are operation-controlled according to the present embodiment are subjected to a predetermined or greater earthquake shake will be described with reference to FIG.

  As shown in FIG. 2, when an earthquake occurs and each of the elevators 30 and 31 receives an earthquake shake (S100), the earthquake detector 11 is activated to detect the earthquake shake and send a signal notifying this earthquake information. Output to control panels 5 and 17, respectively. Receiving this signal, the control panels 5 and 17 perform seismic control operation, respectively, move the elevator cars 30 and 31 to the nearest floor and stop them. Then, after the passengers in the cars 1 and 26 are lowered, the elevators 30 and 31 are stopped.

  Next, when the control panel 5 of the elevator 30 is stopped by the operation information indicating that the car 1 in the elevator 30 is running or stopped when the earthquake occurs, read from the I / F circuit 6, and by the earthquake control operation Information on the elevator 30 such as car position information indicating the position of the car 1 and confirmation information on the number of service floors of the elevator 30 is transmitted to the I / F circuit 9 in the monitoring device 8 (S101). At the same time, the control panel 17 of the elevator 31 is stopped due to operation information indicating that the car 26 in the elevator 31 at the time of the occurrence of the earthquake, which is read from the I / F circuit 18, is running or stopped, and earthquake control operation. Information on the elevator 31 such as car position information indicating the position of the passenger car 26 and confirmation information on the number of service floors of the elevator 31 is transmitted to the I / F circuit 21 in the monitoring device 20 (S101).

  Then, the control panel 5 of the elevator 30 transmits the earthquake information received from the earthquake detector 11 to the monitoring device 8, and the monitoring device 8 determines that the earthquake detector 11 has detected high gal from the received earthquake information. The process is terminated (S102), and the elevator 30 is controlled to be in a dormant state until the worker confirms safety. At the same time, the control panel 17 of the elevator 31 transmits the earthquake information received from the earthquake detector 11 to the monitoring device 20, and the monitoring device 20 determines that the earthquake detector 11 has detected high gal from the received earthquake information. In this case, the process is terminated (S102), and the elevator 31 is controlled to be in a dormant state until the worker confirms safety.

  On the other hand, when it is determined from the earthquake information received by the monitoring devices 8 and 20 in step S102 that the earthquake detector 11 has not sensed high-gull vibration, an elevator monitoring device other than the monitoring device 8 of the elevator 30, that is, The monitoring device 20 of the elevator 31 transmits the information on the elevator 31 received in step S101 to the monitoring device 8 of the elevator 30.

  And this monitoring apparatus 8 compares the operation information of the elevator 30, and the operation information of the elevator 31, respectively, and when it is judged that both the cars 1 and 26 in the elevators 30 and 31 are not stopped at the time of an earthquake occurrence (S103). The monitoring device 8 determines whether the car 1 is running and the car 26 is stopped when the earthquake occurs (S104). If the monitoring device 8 determines that the car 1 is running and the car 26 is not stopped when the earthquake occurs (S104), the car 1 is stopped and the car 26 is running when the earthquake occurs. Is determined (S105).

  When the monitoring device 8 determines in the step S103 that both the cars 1 and 26 are stopped when the earthquake occurs, or in the step S105, the monitoring device 8 determines that the “car 1 is stopped and the car 26 is When it is determined that the vehicle is not “running”, the monitoring device 8 compares the car position information of the elevator 30 and the car position information of the elevator 31, and the position of the car 1 when the car is stopped by the seismic control operation is It is determined whether or not the position is lower than the position (S106). That is, it is determined whether the position of the car 1 is closer to the lowest floor than the position of the car 26, or whether the positions of both cars are the same (S106).

  In step S105, when the monitoring device 8 determines that "the car 1 is stopped and the car 26 is running" when the earthquake occurs, or the car when the monitoring device 8 is stopped due to the earthquake control operation in step S106. When it is determined that the position of 1 is lower than or the same as the position of the car 26, the diagnostic operation setting means included in the control circuit 10 of the monitoring device 8 is given priority to the elevator 30 (the first car) rather than the elevator 31. ) Is prioritized (S107).

  Thereafter, the monitoring device 8 transmits the priority set by the diagnostic operation setting means to a monitoring device other than the monitoring device 8, that is, the monitoring device 20. Then, the diagnostic operation start command included in the control circuit 10 of the monitoring device 8 outputs a diagnostic operation start command to the control panel 5 to start the earthquake recovery diagnosis operation of the elevator 30. If no abnormality is detected in the earthquake restoration diagnosis operation of the elevator 30, the monitoring device 8 outputs a diagnostic operation start command to the monitoring device 20 by the diagnostic operation command means. When the monitoring device 20 receives this diagnostic operation start command, the monitoring device 20 starts the earthquake recovery diagnostic operation of the elevator 31 via the control panel 17.

  Here, each monitoring device other than the monitoring device 8, that is, the monitoring device 20 transmits an end command to the monitoring device 8 after the earthquake restoration diagnosis operation of the elevator 31 that is its own machine is completed. And the monitoring apparatus 8 judges whether all the elevators 30 and 31 were made the earthquake restoration diagnosis driving | operation (S109).

  Here, for example, when the monitoring device 8 determines that both of the elevators 30 and 31 are not in the earthquake restoration diagnosis operation (S109), the diagnosis operation command means is given to the control panel 5 of the elevator 30 having a higher priority than the elevator 31. To output a diagnostic operation start command to start the earthquake recovery diagnosis operation of the elevator 30 (S110). And when abnormality is detected by the earthquake restoration diagnostic driving | operation of the elevator 30 (S111), the monitoring apparatus 8 stops the earthquake restoration diagnostic driving | operation by the diagnostic driving | operation stop means by making the elevator 30 into a specific elevator, and also monitors a diagnostic driving | operation stop command. The start of the earthquake restoration diagnosis operation of the elevator 31 which is output to the device 20 and has a lower priority than the elevator 30 is also stopped.

  If no abnormality is detected in the earthquake restoration diagnosis operation of the elevator 30 in step S111, the monitoring device 8 determines that the earthquake restoration diagnosis operation of the elevator 30 is completed (S112), and the elevator 31 is again operated in the earthquake restoration diagnosis operation. It is determined whether or not it has been made (S109). When the monitoring device 8 determines that the elevator 31 has been operated in an earthquake recovery diagnosis (S109), the operation is terminated, and when it is determined that the elevator 31 is not in an earthquake recovery diagnosis operation (S109), the procedures S110 to S112 are performed. To end the operation.

  On the other hand, when the monitoring device 8 determines in Step S104 that the car 1 is running and the car 26 is stopped when an earthquake occurs, or when the monitoring device 8 is suspended due to the earthquake control operation in Step S106. When it is determined that the position of the car 1 is higher than the position of the car 26, the diagnostic operation setting means included in the control circuit 10 of the monitoring device 8 gives priority to the elevator 31 over the elevator 30 (S108). .

  Thereafter, the monitoring device 8 transmits the priority set by the diagnostic operation setting means to a monitoring device other than the monitoring device 8, that is, the monitoring device 20. The diagnostic operation start command included in the control circuit 10 of the monitoring device 8 outputs a diagnostic operation start command to the monitoring device 20, and the monitoring device 20 starts the earthquake recovery diagnostic operation of the elevator 31 via the control panel 17. If no abnormality is detected in the earthquake restoration diagnosis operation of the elevator 31 via the monitoring device 20, the monitoring device 8 outputs a diagnosis operation start command to the control panel 5 by the diagnosis operation command means, and the earthquake restoration diagnosis operation of the elevator 30 is performed. To start.

  Here, for example, when the monitoring device 8 determines that both of the elevators 30 and 31 are not in the earthquake recovery diagnosis operation (S109), the diagnosis operation command means sends the control panel 17 of the elevator 31 having a higher priority than the elevator 30 to the control panel 17. A diagnosis operation start command is output, and the earthquake recovery diagnosis operation of the elevator 31 is started (S110). And when abnormality is detected by the earthquake restoration diagnostic driving | operation of the elevator 31 (S111), the monitoring apparatus 8 stops the earthquake restoration diagnostic driving | operation via the monitoring apparatus 20 by the diagnostic driving | operation stop means by making the elevator 31 into a specific elevator, A diagnostic operation stop command is output to the control panel 5 to stop the earthquake recovery diagnosis operation of the elevator 30 having a lower priority than the elevator 31.

  If no abnormality is detected by the earthquake restoration diagnosis operation of the elevator 31 in step S111, the monitoring device 8 determines that the earthquake restoration diagnosis operation of the elevator 31 is completed via the monitoring device 20 (S112), and the elevator again. It is determined whether or not 30 has been operated for earthquake restoration diagnosis (S109). Then, when the monitoring device 8 determines that the elevator 30 has been operated in the earthquake recovery diagnosis (S109), the operation is terminated, and when it is determined that the elevator 30 is not in the earthquake recovery diagnosis operation (S109), the procedures S110 to S112 are performed. To end the operation.

  In the present embodiment configured as described above, the diagnostic operation setting means included in the control circuit 10 of the monitoring device 8 is based on the operation information and car position information of the elevators 30 and 31 in steps S103 to S106, in steps S107 and S108. The priority order of the elevators 30 and 31 for performing the earthquake recovery diagnosis operation is set in the order of the elevators that are highly likely to be normal. Since the earthquake recovery diagnosis operation is started, the elevator with no abnormality can be quickly recovered.

  When the monitoring devices 8 and 20 detect an abnormality in either one of the elevators 30 and 31 by the earthquake restoration diagnosis operation in step S111, the monitoring device 8 detects the abnormality by the diagnosis operation stopping means included in the control circuit 10. Since the detected elevator is used as the specific elevator and the earthquake recovery diagnosis operation is stopped, it is possible to avoid the specific elevator from failing by continuing the earthquake recovery diagnosis operation.

  Further, after the procedure S107, when the monitoring devices 8 and 20 detect an abnormality in both the elevators 30 and 31 by the earthquake restoration diagnosis operation in the procedure S111, the diagnosis restoration operation of the elevator 30 is stopped by the diagnosis operation stopping means. Since the start of the earthquake restoration diagnosis operation of the elevator 31 that is more likely to be abnormal than the elevator 30 is stopped, it is possible to avoid the elevators 30 and 31 from failing simultaneously due to the earthquake restoration diagnosis operation. In addition, after the procedure S108, when the monitoring devices 8 and 20 detect an abnormality in both the elevators 30 and 31 by the earthquake restoration diagnosis operation in the procedure S111, the diagnosis restoration operation of the elevator 31 is stopped by the diagnosis operation stopping means. Since the start of the earthquake restoration diagnosis operation of the elevator 30 that is more likely to be abnormal than the elevator 31 is stopped, it is possible to avoid the elevators 30 and 31 from being simultaneously damaged by the earthquake restoration diagnosis operation.

  Thus, this embodiment can avoid the failure accompanying an earthquake restoration diagnostic driving | operation, and can improve the safety | security of an elevator. In particular, since the failure of the plurality of elevators 30 and 31 is prevented from worsening with the earthquake restoration diagnosis operation, the time required for restoration can be reduced, and the serviceability of the elevator can be improved.

  Further, in the present embodiment, the diagnostic operation setting means included in the control circuit 10 of the monitoring device 8 indicates that each of the cars 1 and 26 in the elevators 30 and 31 is running or stopped when an earthquake occurs. The priority order for the earthquake restoration diagnosis operation is set based on the information of the two detectable elevators 30 and 31 including the information and the car position information indicating the position of each of the cars 1 and 26 when the car is stopped by the seismic control operation. Thus, the error between the set priority order of the elevators 30 and 31 and the order in which the actual elevators 30 and 31 are less likely to be abnormal can be reduced. Thereby, the reliability with respect to the earthquake restoration diagnosis driving | operation of an elevator can be improved.

  Further, in the present embodiment, the diagnostic operation setting means included in the control circuit 10 of the monitoring device 8 is configured so that, in steps S103 to S105, when the earthquake occurs, the elevators 30 and 31 are more likely to travel when the earthquake occurs than when the elevator is traveling. The elevator in which the car is stopped is prioritized, and in steps S106, the cars 1, 26 in the elevators 30, 31 when the cars 1, 26 are stopped due to the seismic control operation among the elevators 30, 31 in the event of an earthquake. In step S106, the elevators 1, 26 of the elevators 30, 31 when the elevators 1, 26 are stopped due to the seismic control operation among the elevators 30, 31 stopped at the time of the earthquake in step S106 are given priority. Priorities are set in preference to elevators with lower positions.

  Here, at the time of the occurrence of an earthquake, the elevators in which the cars 1 and 26 are stopped are less likely to cause an abnormality in the elevator due to the earthquake than the elevators in which the cars 1 and 26 in the plurality of elevators 30 and 31 are traveling. . On the other hand, when the operation information of the cars 1 and 26 in the plurality of elevators 30 and 31 is the same at the time of the earthquake occurrence, the lower the position of the cars 1 and 26 when the operation is stopped by the seismic control operation, Anomalies are less likely to occur.

  For this reason, the diagnostic operation setting means of the monitoring device 8 sets the priority order for the earthquake recovery diagnostic operation as described above, and follows the operation procedure of S103 to S106 according to the operation information of the elevators 30 and 31 and the car position information. The priority order can be reasonably set in the order of elevators that are highly likely to be free of abnormality.
