Safe elevator door lock safety circuit and implementation method thereof

Abstract

The invention relates to a safe elevator door lock safety circuit and an implementation method thereof. The elevator door lock safety circuit comprises various safety contact circuits of a well and a car, a landing door main door lock and car door lock circuit and a landing door lock jumper circuit. The elevator stopping alarm function can be achieved when the main door and the auxiliary door of the first-floor landing door are accidentally opened. And meanwhile, debugging and maintenance personnel can conveniently carry out short circuit of a single landing door or all landing doors, if the short-circuit wire is forgotten to be recovered, the system can continuously report a fault and prompt to recover the short-circuit wire, and personal injury caused by forgotten to recover the landing door short-circuit wire by the maintenance and debugging personnel is ensured. The door lock safety loop has redundancy design, it is guaranteed that the door lock loop of a certain floor cannot be forgotten to be installed due to man-made reasons in the initial installation stage, and the situation that the door lock loop is unsafe is avoided. And meanwhile, under the condition that the distance between the middle layers is too long, only corresponding middle layer bridging cables and single-floor short-circuit wires need to be added, and designers can carry out door lock loop cable type selection design very conveniently.

Description

technical field [0001] The invention relates to the technical field of elevator manufacturing, in particular to a safe elevator door lock safety circuit and a realization method thereof. Background technique [0002] The competition in the elevator market is becoming increasingly fierce, and customers are paying more and more attention to the cost, function and safety of elevators. At the same time, the installation and maintenance department is also paying more and more attention to the convenience and maintainability of elevator installation. As an important function of the elevator, the elevator floor car door detection and alarm system needs to take into account all aspects. [0003] In the past, the safety circuit of the elevator was in the form of connecting safety contacts, door locks on each floor, and car door locks in series. Although the original solution was simple, it was inconvenient to short-circuit the floor door locks, and the door locks might be missed. If...

[0003] In the past, the safety circuit of the elevator was in the form of connecting safety contacts, door locks on each floor, and car door locks in series. Although the original solution was simple, it was inconvenient to short-circuit the floor door locks, and the door locks might be missed. If you forget to restore the floor door lock, it is easy to cause accidents
