Elevator safety circuit fault detection system, method and equipment and storage medium

Abstract

The invention provides an elevator safety circuit fault detection system, a method and equipment and a storage medium. The system comprises N first electronic safety controllers and a second electronic safety controller, and N is an integer greater than or equal to 1; each first electronic safety controller communicates with the second electronic safety controller through a safety bus; each first electronic safety controller is connected with a plurality of first safety switches, obtains state signals of the first safety switches and sends the state signals to the second electronic safety controller; the second electronic safety controller is connected with a plurality of second safety switches, obtains the state signals of the second safety switches and controls an elevator brake control device to be switched off or switched on according to the state signals of the first safety switches and the state signals of the second safety switches. According to the elevator safety circuit fault detection system, the method and the equipment and the storage medium, a safety loop function can be realized without complicated wiring, and the diagnosis of a safety loop is simplified.

Description

technical field [0001] Embodiments of the present invention relate to the field of elevator control, and more specifically, relate to a system, method, device and storage medium for fault detection of an elevator safety loop. Background technique [0002] With the development of cities, high-rise buildings are rising frequently, and the use of elevators is becoming more and more popular. Elevator is a kind of equipment that moves vertically between different floors in the hoistway. There are car doors on the elevator car, and hall doors are correspondingly set on the wall of the hoistway to lead to each floor. The opening of the car doors and hall doors allows passengers to In and out of the car. [0003] In order to ensure the safe operation of the elevator, multiple electrical safety devices are installed on the elevator, and the elevator can only run when each electrical safety device is normal. Such as figure 1 As shown, each electrical safety device corresponds to a ...
