Anti-skidding control plate for braking control system of rail transit vehicle

Abstract

The invention provides an anti-skidding control plate for a braking control system of a rail transit vehicle. The anti-skidding control plate comprises a frequency input port, a master control chip, a power output port and a data bus port, wherein the frequency input port is used for receiving a rotating speed signal of a vehicle axial speed sensor; the master control chip is connected to the frequency input port and the power output port and is used for sending a control signal of an anti-skidding valve from the power output port by performing an anti-skidding control logic calculation afteracquiring the rotating speed signal; the power output port is used for performing matching conversion on the anti-skidding control signal generated by the master control chip and then controlling theanti-skidding valve; and the data bus port is connected to other functional board cards except the anti-skidding control plate in the braking control system. The anti-skidding control plate for the braking control system of the rail transit vehicle provided by the invention sends a control instruction after utilizing the master control chip to collect and analyze speed information, controls the anti-skidding valve so as to control the size of a wheel braking force, has an excellent anti-skidding effect and promotes the reliability of the braking control system.

Description

technical field [0001] The invention relates to the braking technology of rail transit vehicles, in particular to an anti-skid control plate used in a braking control system of rail transit vehicles. Background technique [0002] The braking control system of rail vehicle is an important functional system to control the deceleration and parking of the vehicle. The safety of vehicle operation is closely related to the reliability of the braking control system. [0003] When the rail vehicle runs at high speed, the kinetic energy increases, and the braking force must also be increased in order to shorten the braking distance. In the case of sticking braking, coasting occurs when the braking force exceeds the wheel-rail adhesion. Antiskid control can be realized by controlling the magnitude of the braking force not to exceed the sticking force. [0004] The existing anti-skid control device in our country is generally installed on the rail vehicle as a separate auxiliary devi...
