Double-door linkage shielding door control method based on correlation sensing

Abstract

The invention relates to the technical field of shielding doors, in particular to a double-door linkage shielding door control method based on correlation sensing. The shielding door control method comprises the following steps of arrival door opening, signal acquisition, processing by a central control system according to an acquired signal, processing by a door machine controller according to acontrol signal of the central control system, door closing controlled by the door machine controller, feeding back a locking signal of a sliding door to the central control system by the door machinecontroller, and controlling the subway to close the door and leave the station by the central control system after receiving the locking signal of the sliding door. According to the shielding door control method, tooth-shaped belt transmission is adopted, on one hand, it is guaranteed that transmission precision is accurately controlled, on the other hand, double-door linkage and synchronous opening or closing of sliding doors can be achieved, and the shielding door control method has the advantages of simple structure and easy control. People flow information can be accurately acquired on thebasis of correlation sensing and weight sensing dual signal induction, the central control system processes the people flow information according to different signal types to control the door machinecontroller, it is guaranteed that the shielding doors are opened and closed in time, and people clamping accidents are prevented.

Description

technical field [0001] The invention relates to the technical field of screen doors, in particular to a control method for double-door linkage screen doors based on cross-beam sensing. Background technique [0002] The rail transit screen door system is installed on the edge of the platform of rail transit stations such as subways and light rails to isolate the track from the platform waiting area. The closed full-height screen door system has the functions of energy saving and noise reduction, creating a comfortable waiting environment for passengers. [0003] The screen door system includes mechanical and electrical parts. The mechanical part includes the door structure and the door machine system, and the electrical part includes the power system and control system. The door body structure is generally composed of sliding doors, fixed doors, emergency doors, end doors, door machine top boxes and connecting structures, etc. The door machine is composed of a driving mechan...

AI Technical Summary

Problems solved by technology

[0004] The screen door system is a system engineering product integrating construction, machinery and electronics, and has high reliability requirements. Although the conventional screw transmission method can achieve precise control, it cannot realize double-door transmission. Although the conventional belt transmission method can realize double-door transmission, but the precision control is slightly poor
