Elevator control apparatus

Abstract

Provided is an elevator control apparatus, comprising a sling winch used in usual with the elevator cage driven by a sling, a drive circuit used in usual for driving the sling winch for usual use, a sling winch for driving the sling for rescuing, a drive circuit used for driving the sling winch used for rescuing, a master control apparatus for controlling the drive circuit for usual use, an auxiliary control apparatus for controlling the drive circuit used for rescuing, and an elevator cage controlling apparatus, wherein the auxiliary control apparatus comprises a caged passenger rescuing control portion. When the master control apparatus is in the state of out of control, the caged passenger rescuing control portion drives the sling winch for rescuing and moves the elevator cage to the motion position of elevator cage stoppable position detecting switch, thereby realizing the objective of moving the caged passengers out of the elevator cage without depending on the master control apparatus when something is wrong with the master control apparatus.

Description

technical field [0001] The present invention relates to an elevator control device, and more particularly to an elevator control device capable of moving the elevator car in the event of a failure. Background technique [0002] When a power failure or the like occurs during elevator operation, passengers in the elevator will be trapped in the elevator car. In this case, usually, a backup battery or a self-contained power generation device installed in a building such as a building is used as a power source to perform operation (rescue operation) to rescue passengers trapped in the elevator car. [0003] However, when the battery is used for the rescue operation, for example, when frequent power outages occur and the rescue operation is frequently performed, sometimes the battery cannot be charged in time and the rescue operation cannot be performed. [0004] In addition, since most buildings are not equipped with self-contained power generating devices, as a rescue measure ...

AI Technical Summary

Problems solved by technology

[0011] However, when the method disclosed in the above-mentioned Patent Document 1 is adopted, it is necessary to dispatch a rescue worker to the scene, and the rescue worker operates the elevator control device to perform passenger rescue operation, and it takes a long time until the passenger is rescued.

In addition, since the operation is carried out in the hoistway of the elevator, it makes the work difficult

[0012] In addition, when using the method disclosed in Patent Document 2, it is necessary to use the power from the battery to automatically start the rescue device, and release the main brake intermittently to move the elevator car to the point where passengers trapped in the elevator car can be rescued. Rescue the passengers after the position of the vehicle, so the rescue work cannot be carried out in the case of a failure of the brakes, etc.

In addition, since the rescue operation is performed using the elevator control device that is used for control in the normal state, when it is judged that the restart cannot be performed due to a failure of the control equipment, etc., the rescue operation cannot be performed.
