Embodiment Construction

[0019] The scissor door system using the brushless DC motor as the power source proposed by the present invention improves the reliability, safety and traffic efficiency of the system from various aspects. Firstly, the reliability of the system is improved by using the brushless DC motor as the power source; secondly, the safety of the system is improved by realizing the pinch protection function through the motor controller; secondly, the traffic efficiency of the gate is improved by reducing the opening / closing time.

[0020] figure 1 It is a scissor door system diagram driven by a brushless motor, and its main working principle is as follows:

[0021] The system includes a frame, a door, a four-bar mechanism, a motor, a motor controller, an arc guide rail, a spring, and a limit block. The fan door, four-bar mechanism, motor, motor controller, arc guide rail and limit block are all installed on the frame. The motor used is a brushless DC motor. A four-bar mechanism includ...

Abstract

The invention provides a brushless motor drive based scissors door system comprising frames, doors, four-bar mechanisms, motors, motor controllers, arc guides, springs and limiters. The doors, the four-bar mechanisms, the motors, the motor controllers, the arc guides and the limiters are all mounted on the frames. The motors are brushless direct-current motors. Each four-bar mechanism comprises a crank and a connecting bar. The brushless motor drive based scissors door system is capable of protecting people from being pinched during door closing and automatically opening doors in case of system power failure; the brushless direct-current motor are driven to serve as power sources to open or close the doors by mean of a PWM-ON control algorithm, the system is better in reliability, stability and applicability, the service life of the system is prolonged, and maintenance cost is lowered.

Description

technical field [0001] The invention relates to a gate at a rail transit station, in particular to a traffic control system in the gate. Background technique [0002] The gate is an important part of the automatic fare collection (Automatic Fare Collection, AFC) system of rail transit, which is used for automatic ticket inspection and traffic control of passengers entering and leaving the station. The gate system is composed of three parts: automatic ticket checking system, passenger passage location recognition system, and passage control system. The scissor gate system proposed by the present invention belongs to the traffic control system of the turnstile. [0003] As the name suggests, the function of the automatic ticket checking system is to check tickets when passengers enter and exit the station. The function of the passenger passage position recognition system is to recognize the position of the passenger walking in the passage after checking the ticket, and send ...
