A control method for double-door linkage shielded doors based on cross-beam sensing

Abstract

The present invention relates to the technical field of shielded doors, in particular to a method for controlling double-door linkage shielded doors based on cross-radiation sensing, which includes the steps of opening the door at the station, the step of signal collection, the step of central control system processing according to the collected signal, and the door operator. The controller performs processing according to the control signal of the central control system, the door machine controller controls the steps of closing the door, the door machine controller feeds back the sliding door locking signal to the central control system, and the central control system controls the subway to close the door after receiving the sliding door locking signal. The steps of the station are driven by a toothed belt. On the one hand, the transmission accuracy is guaranteed to achieve precise control. On the other hand, the sliding door can be linked with two doors and opened or closed synchronously. It has the advantages of simple structure and easy control. Based on the dual signal induction of beam sensing and weight sensing, it can accurately collect information on the flow of people. The central control system processes according to different types of signals, and controls the door machine controller to ensure timely opening and closing of screen doors and prevent pinching accidents. .

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...

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
