Reference numerals 71 to 173 denote three elevators installed in the building 10.

[0006] In the monitoring base 20, the elevators 171 to 173 can be operated from a remote place. Specifically, in the event that a disaster such as a typhoon can be expected, the car of the elevators 171 to 173 is prevented from being flooded. Stop floor shift operation for stopping at a specific floor during elevator non-use time, elevator 17
This is a case where a remote inspection operation or the like is performed to confirm from a remote location whether or not the normal operation of Nos. 1 to 173 is performed.

FIG. 2 is a flowchart of the elevator remote control performed at the monitoring base 20. The operation of the elevator remote control will be described with reference to FIG. First, the monitoring base 20 calls the telephone number of the shared public line T0 of the elevators 171 to 173 installed in the building 10 (S1). A calling signal is transmitted to the modem communication units 111 to 113 (S2), and it is determined whether or not any of them is connected (S3). If the result of the determination is negative, the procedure returns to step S2 to transmit the calling signal. Is repeated, and if the result of the determination is correct, a remote operation execution command signal is transmitted to the monitoring terminal 1i that has received the call signal (S4). This remote operation execution command signal includes data of designation of the elevator to be remotely operated and data of operation and control details to be executed. Thereafter, the elevator 17m (m = 1 to 3) is remotely operated, and the monitoring terminal 1m
After receiving the status data of the elevator 17m from the modem communication unit 11m (S5), it is determined whether or not the processing for the elevator 17m is completed (S6). If the determination result is no, the process returns to step S5 to return to the elevator. The reception of the state data of 17 m is repeated, and if the result of the determination is correct, the operation of the elevator remote control ends.

FIG. 3 is a flow chart of the incoming call monitoring terminal control of the monitoring terminal 1i which is called from the monitoring base 20 and receives the remote control execution command signal. The operation of the incoming call monitoring terminal control will be described with reference to FIG. First, it is determined whether or not a call signal has been received from the monitoring site 20 (S1).
1). If the result of the determination is negative, this process ends. If the result of the determination is true, a remote operation execution command signal is received from the monitoring site 20 (S12). Then, it checks the elevator designation data included in the remote operation execution command signal and determines whether or not the data includes a designation of another elevator 17j (S13). If the determination result is correct, a remote operation execution command signal including operation / control content data to be executed is transmitted to another monitoring terminal 1j that monitors the elevator 17j via the inter-terminal communication line T1 ( S14). If the result of the determination in the step S13 is negative, the procedure moves to the next step S15 without going through the step S14.

In step S15, it is determined whether or not the received remote control execution command signal includes the own device, that is, the one specifying the elevator 17i. If the judgment result is correct, the operation and control of the elevator 17i of the own unit are performed according to the operation and control content data included in the execution command signal of the remote operation.
The control is executed (S16). Then, it is determined whether or not the operation / control for remotely operating the elevator 17i of the own machine has been completed (S17).
16, the operation and control of the elevator 17i of the own machine are completed, and the judgment result is correct, or the procedure S15 is performed.
If the judgment result is NO, the process moves to the next step S18.

In step S18, the status data is registered in accordance with the non-incoming call monitoring terminal control process executed by the monitoring terminal 1j of the other device, which will be described later. The status contents such as “in execution”, “completed”, and “abnormally terminated” for the operated operation / control are checked. Then, status transmission data is created in accordance with the operation and control results for the elevator 17m whose operation and control has been instructed by the remote operation execution command signal (S19), and transmitted to the monitoring base 20 (S20). Then, the state transmission data is checked, and the operation /
It is determined whether or not the operation / control has been completed for all the elevators 17m for which control has been instructed (S21). If the result of the determination is no, the process returns to step S18 to investigate the state contents for the instructed operation / control. Is repeated, and if the determination result is correct, the process of the incoming call monitoring terminal operation control is terminated.

FIG. 4 is a flow chart of the non-arrival monitoring terminal control executed by the monitoring terminal 1j of the other unit which has not received the call signal from the monitoring base 20. The operation of the non-arrival monitoring terminal operation control will be described with reference to FIG. First, a remote operation execution command signal including operation / control content data to be executed from the monitoring terminal 1i that has received a call signal from the monitoring base 20 is received via the inter-terminal communication line T1 (S31).
Then, according to the operation / control content data included in the execution command signal, the operation / control of the elevator 17j of the other car is executed (S32). Next, the current elevator 17j
The state of the operation / control is checked, and the execution state data for the operation / control indicated in the corresponding column of the above-mentioned elevator state list is registered (S33). Then, it is determined whether the operation / control indicated by the remote operation execution command signal has been completed (S34). If the result of the determination is negative, the procedure returns to step S32 to execute the specified operation / control. Carry out,
If the determination result is correct, the process of controlling the non-arrival monitoring terminal is terminated.
