DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an elevator rescue operation device of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of an elevator rescue operation apparatus of the present invention, FIG. 2 is an explanatory view showing an example of failure determination contents stored in a first storage section, and FIG. 3 is FIG.
It is a flow chart which shows the processing procedure of the rescue operation device.

In a building equipped with an elevator (not shown), an elevator controller 1 for controlling the operation of the elevator as shown in FIG. 1 and an elevator for performing a rescue operation when the elevator is stopped due to an abnormality occurrence. A rescue operation device 2 is provided, while the rescue operation device 2 is connected via a communication line T to a monitoring center 3 that remotely monitors the elevator.

Further, the above-mentioned elevator control device 1 is provided with a first storage section 11 for storing the contents of failure judgment when the elevator is stopped due to the occurrence of an abnormality, while the above-mentioned rescue operation device 2 is provided. Is a failure determination content collecting unit 21 that reads the failure determination content from the first storage unit 11 and stores the failure determination content in the second storage unit 22 when an elevator abnormality occurs, and whether or not rescue operation is possible based on the failure determination content. Based on the analysis result of the failure determination content analysis unit 23 and the failure determination content analysis unit 23, and the rescue operation for performing the rescue operation of the elevator by erasing the failure determination content stored in the first storage unit 11. A failure determination content erasing unit 25 that outputs a signal to the elevator control device 1, and a rescue operation signal monitoring unit 26 that monitors whether or not the rescue operation is performed according to the output of the rescue operation signal.

There is.

Then, as shown in FIG. 2, the details of the failure determination stored in the first storage device 11 in the elevator control apparatus 1 are recorded in coded numbers when the failure occurs in the elevator. For example, when the code indicating the failure name is "20", it indicates a rotary encoder failure, that is, a failure when the pulse of the rotary encoder that controls the speed of the car cannot be detected. In this way, there are several types of coded faults, and other fault discrimination details include the stop floor at the time of the fault, speed, each device,
For example, there are door open zones and ON / OFF operation states of door switches. In addition, in the code of the failure name, the stopped state of the elevator is classified into a recoverable one and a non-recoverable one when the failure is recovered. In the event of a failure in which foreign matter is caught and the door does not close completely, recovery is possible when foreign matter is removed, but in the event of a failure of high importance, such as the failure of the rotary encoder that controls the electric motor, even if the failure recovers, the elevator It is designed not to recover the stopped state of. However, even if the failure cannot be recovered, the rescue operation is tried by deleting the failure determination content stored in the first storage device 11 in the elevator control device 1. Therefore, by analyzing the content of the failure determination configured as described above, it is possible to know whether or not the rescue operation is possible, and even if the failure cannot be recovered, for example, a transient failure such as a contact failure of the relay. In this case, if the contact failure is corrected, the rescue operation can be performed by recovering.

Next, in step S3, whether or not the elevator can be restored is analyzed from the failure code of the failure determination content, and when the failure cannot be recovered, in order to safely operate the elevator, the failure determination content analysis unit 23 in step S4. Analyzes the failure state from the details of the failure determination. At this time, for example, the safety device of the elevator, that is, the speed over switch of the speed governor, the forced stop switch of the end floor, etc. are not operating, and the switch for detecting that the landing door is closed and the car When it is determined that the switch that detects that the door is closed is operating, step S5
Then, the failure determination content erasing unit 25 erases the failure determination content stored in the first storage device 11 and outputs a rescue operation signal for performing the rescue operation of the elevator to the elevator controller 1. Along with this, in step S6, the car moves to the nearest floor, the rescue operation of opening the door is performed, and the rescue operation signal monitoring unit 26 monitors the rescue operation. After that, as shown in step S7, the suspension signal output unit 27 outputs a suspension signal for suspending the elevator to the elevator control device 1 to put the elevator in a suspension state.

Next, in step S8, the communication section 24
Transmits the output data including the failure determination content stored in the second storage unit 22 and the result of the failure determination content analysis, the rescue operation signal and the suspension signal to the monitoring center 3 through the communication line T, while monitoring At the center 3, the failure name is displayed from the failure code of the failure determination content, and the failure status and the implementation status of the rescue operation are displayed. As a result, the supervisor of the monitoring center 3 can understand the failure content and failure status of the elevator and can investigate the cause of the failure. Furthermore, by confirming whether or not the rescue operation of the elevator has been performed, the expert engineer can be urgently urged. It's supposed to decide if you need to be dispatched to.

In the embodiment thus constructed, when a containment failure occurs, the rescue operation can be performed without manpower, and the passengers can be rescued promptly and reliably. Further, by transmitting the storage contents of the second storage unit 22 to the monitoring center 3, the response personnel can surely grasp the cause of the failure.
