Next, the operation of the elevator control device having the above configuration will be described. When monitoring the state of the elevator, the elevator control unit (elevator group management device 30)
The elevator state signal creating means 23 is the elevator 26
The transmission means 1
Elevator monitoring unit (elevator monitoring device 5
0) is transmitted. Then, the elevator monitoring unit (elevator monitoring device 50) uses the transmission means 19
Display control means 17 receives the elevator status signal from
A process of displaying on the display 18 is performed.

When carrying out a disaster operation, the elevator monitoring section (elevator monitoring device 50) receives the disaster operation control means 16 and the input means 13 (the display control means 17 receives the information input by the input means 13). (Displayed on the display 18), the self-generated detection means 12, the earthquake detector 11,
Some kind of disaster is detected by the information from the power failure detector 14 and the fire detector 15, and the disaster operation control information corresponding to the disaster is output to the transmission means 19. Further, in order to display the disaster information on the display device 18, a process of outputting the disaster information to the display control means 17 is performed. Then, in the elevator group management device, the disaster operation control information receiving means 21 receives the disaster operation control information from the transmission means 19 and outputs it to the disaster operation executing means 24. The disaster operation execution means 24 converts the disaster operation control information into a signal for actually controlling the elevator and outputs the signal to the elevator control means 25, and the elevator control means 25 controls the elevator 26.

On the other hand, the elevator monitoring unit (elevator monitoring device 50) has an elevator monitoring unit normal signal output means 20.
By this, a normal signal is periodically output to the transmission means 19. In the elevator control unit (elevator group management device 30), the elevator monitoring unit abnormality determination unit 22 determines whether or not the elevator monitoring unit is abnormal based on the monitoring unit normal signal received from the transmission unit 19.

Then, the elevator control device having the above-mentioned configuration performs the following operation (operation of claim 1). The disaster operation control means 16 detects a disaster from an external input and outputs it to the transmission means 19. Disaster operation control information receiving means 21
Receives the disaster operation control information from the transmission means 19, converts it into the actual elevator control signal by the disaster operation execution means 24, sends the operation pattern to the elevator control means 25, and sends the elevator 26 the first disaster operation signal. Let However, when the monitoring unit normal signal periodically sent from the elevator monitoring unit normal signal output unit 20 to the transmission unit 19 is not received, the elevator monitoring unit abnormality determination unit 22 causes the elevator monitoring unit (elevator monitoring device 50) to operate. It is considered to be abnormal, and abnormal information is output to the disaster operation executing means 24, and the disaster operation executing means 24 outputs an elevator control signal to the elevator control means 25 so as to perform the second disaster operation. Note that this operation can be grasped as the operation of claim 6.

Further, in the above operation (the operation of claim 1), when the elevator monitoring unit abnormality determining means 22 outputs the abnormality information of the elevator monitoring unit to the disaster time operation executing means 24, the disaster time operation executing means 24 loses power. The information of the detector 14 is used to ignore the information of the automatic operation input by the input means 13 and output the return operation command at the time of power failure to the elevator control means 25 (operation of claim 2).

Further, in the above operation (operation of claim 1), when the elevator monitoring unit abnormality determining means 22 outputs the abnormality information of the elevator monitoring unit to the disaster operation executing means 24, the disaster operation executing means 24 is operated by the machine. Based on the information from the earthquake detector 27 installed in the room, the elevator control means 25 outputs a return operation command at the time of an earthquake (operation of claim 3).

Further, in the above operation (operation of claim 1), when the elevator monitoring unit abnormality determination means 22 outputs the abnormality information of the elevator monitoring unit to the disaster time operation execution means 24, the disaster time operation execution means 24 Based on the information of the fire detector 15, a return operation command at the time of fire is output to the elevator control means 25 (operation of claim 4).

Further, in the above operation (operation of claim 1), when the signal that the backup operation switch 28 is turned on is input to the disaster operation operation executing means 24, the information of the elevator monitoring unit abnormality determining means 22 is ignored. And outputs a second disaster operation control signal to the elevator control means 25 (operation of claim 5).

Next, each means of this elevator control device will be explained using a flow chart. FIG. 3 is a flowchart showing the elevator monitoring unit normal signal output means of the elevator control apparatus according to the embodiment of the present invention, which is a process incorporated in the elevator monitoring unit normal signal output means 20 in the principle block diagram of FIG. This processing is performed by the transmission means 1
9 is a process of periodically outputting a monitoring unit normal signal. In the figure, step S1 is a process of waiting for a predetermined time for outputting the monitoring unit normal signal. When the predetermined time has elapsed, the process proceeds to step S2 and the process of outputting the monitoring unit normal signal to the transmission means 19 is performed. If the predetermined time has not passed, this process is left as it is.

FIG. 4 is a flow chart showing an elevator monitoring unit abnormality judging means of the elevator control apparatus according to one embodiment of the present invention, which is a process incorporated in the elevator monitoring unit abnormality judging means 22 in the principle block diagram of FIG. .
This process is a process of determining an abnormality of the monitoring unit based on the monitoring unit normal signal sent through the transmitting means 19 by the process of FIG.

In the figure, in step S31, the status signal of the power failure detector 14 is sent via the monitoring unit, and it is determined whether or not a power failure has occurred according to the status signal. If no power failure has occurred, this processing is exited. If a power failure has occurred, a status signal of the private air traffic control detecting means 12 is sent via the monitoring unit in step S32, and it is determined whether the private power generation is established by the status signal. If the in-house start has not been established, the process of step S32 is continued until the in-house start is established. If self-starting is established, the input means 1 of the monitoring unit is set in step S33.
It is determined whether or not the automatic return switch signal input from 3 is on the automatic side. In the case of automatic, a return command is output to the elevator in step S34. Then, in step S35, it is determined whether or not the elevator return operation is completed, and if the return operation is not completed, wait until it is completed. If the return operation is completed, in step S36, the elevator is in the continuous operation cage. Determine whether or not. If it is not the continuous operation car, the process is directly exited. If it is the continuous operation car, the process proceeds to step S37 to output the continuous operation command to the elevator. On the other hand, if the automatic return switch signal is not automatic, that is, if it is manual, it is determined in step S38 whether the status signal of the continuation switch input by the input means 13 of the elevator monitor is ON. If the continuation switch status signal is ON, the process proceeds to step S37. If the continuation switch signal is OFF, it is determined in step S39 whether or not the status signal of the return switch input by the input means 13 of the elevator monitoring unit is ON, like the continuation switch.

When the vehicle stops at the nearest floor, the nearest floor stop command is output to the elevator in step S53. Then, in step S54, a stop command is output to the elevator. If it is not possible to stop at the nearest floor in a short time, a sudden stop command is output to the elevator in step S55. Then, in step S56, it is determined whether or not an earthquake of 150 GAL or more has occurred according to the status signal of the earthquake detector 11 sent via the monitoring unit. If an earthquake of 150 GAL or more has not occurred, in step S57,

On the other hand, 150G
If an AL or greater earthquake occurs, in step S60,
It is determined whether or not the state signal of the earthquake low speed switch input by the input means 13 of the monitoring unit is ON, and if it is OFF, wait until it becomes ON, and if it is ON, the door close button in the elevator car at step S61. While pressing, the low-speed automatic operation command is output, and it is determined in step S62 whether or not the nearest floor stop has been performed. If the nearest floor is not stopped, the process of step S61 is performed again. If the nearest floor has been stopped, the process proceeds to step S54.

In the figure, in step S71, it is determined whether or not an earthquake of 100 GAL or more has occurred based on the information from the earthquake detector 27 installed in the machine room. If an earthquake of 100 GAL or more has not occurred, this processing is directly exited. If an earthquake of 100 GAL or more has occurred, it is determined in step S72 whether the elevator will stop at the nearest floor in a short time. When the vehicle stops at the nearest floor in a short time, the nearest floor stop command is output to the elevator in step S73, and the stop command is output to the elevator in step S74. On the other hand, if it is not possible to stop at the nearest floor in a short time, a sudden stop command is output to the elevator in step S75, and a low speed automatic operation command is output while the door lock button in the elevator car is being pressed in step S76. . Then, in step S77, it is determined whether or not the vehicle has stopped at the nearest floor.
