る。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device in which the operation of a plurality of elevators is controlled by each control device, and when a failure in the control device is detected, the elevator operation is controlled by another elevator control device. This invention relates to an elevator control device switching method.

常電源（電池）を有する駆動装置で行なわせ、かごを最
寄り階へ走行させるものがあった。Conventionally, when an elevator stops midway through the hoistway due to a power outage in the elevator control system, the method of moving the car to the nearest floor and rescuing passengers is to operate the elevator using a drive device with an emergency power source (battery). There was one that made the car run to the nearest floor.

（特開昭６３−１０１２９１号）方式が提案されていた
。In addition, in cases where multiple elevators are controlled by their own control devices, if one control device fails, the control device for that elevator is temporarily replaced with the control device for the adjacent elevator, and the elevator is moved to the nearest floor. A method was proposed (Japanese Unexamined Patent Publication No. 101291/1983) in which passengers were rescued by having the train run to the train station to rescue the passengers who were trapped in it.

。The elevator control switching method according to the present invention includes a switching circuit for switching the drive control output of each elevator to an elevator that cannot be operated under control, and a communication line between the inside of the elevator car and the elevator monitoring center, for each elevator operated by the drive control means. The elevator system is equipped with a transmitting/receiving circuit for transmitting and receiving information and receiving a drive control output switching instruction from an elevator monitoring center, and a switching instruction means for giving a switching instruction to the switching circuit when the drive control output switching instruction is received.

出力の切換指示手段へ指示信号を出力するものである。In this invention, if an operating elevator stops due to a failure in the drive control means and control operation becomes impossible, the elevator monitoring center is notified of this via a transmitting/receiving circuit from inside the car, and the monitoring center can ascertain the cause of the inoperability. After that, an instruction signal is sent to the drive control output switching instruction means to stop the other elevator currently in operation at the nearest floor and output the drive control output of this elevator to the elevator that has become inoperable via the switching circuit. This outputs the following.

After the monitoring center staff confirms this, the status of the BVLM is then confirmed via the intercom of Unit B. If there are passengers in Unit B, confirm on the intercom that the passengers have disembarked after arriving at the floor called for, and send the message to the control device (13b).
Give an instruction to close the car door (not shown) of the car. Thereafter, the transmitting/receiving device (21) of the monitoring center (21) sends an instruction to open the contact (6a) to the control device (13a) of machine a via the transmitting/receiving device (17) on the elevator side, and the control device of machine b ( 13b) to open the contact (8b). With this opening instruction, each motor (7a), (7b
) are separated from the inverter (5a) and (5b) outputs. Next, according to the connection instruction from the monitoring center (20), the control device (13b) of unit B closes the contact (15) and connects the output of the inverter (5b) of unit B to the motor (7a) of unit A. . As a result, the inverter (5b) and control device (1, 3b) are used to drive the car No. A at low speed to the nearest floor and rescue the passengers.
