Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1, the present utility model provides a technical solution: an anti-collision device of a cargo lift door comprises a lift car control panel 1 and an induction assembly 2 arranged on the lift door;

the elevator control system comprises an elevator control system, wherein a car control board 1 is a part of the elevator control system, a first terminal JP6.1, a second terminal JP6.2, a third terminal JP6.3 and a fourth terminal JP6.4 are arranged on the car control board 1, the first terminal JP6.1 and the second terminal JP6.2 are control main board instruction receiving terminals, and the third terminal JP6.3 and the fourth terminal JP6.4 are on-off signal collecting terminals and power supply terminals of an induction component 2;
