Abstract

The invention provides control system and method for an electromagnetic type magnetic track brake. The control system comprises the electromagnetic type magnetic track brake, a control unit, a power supply control module and a power supply; the control unit is connected with the power supply control module and connected to the power supply through a controllable switch, and the control unit is used for turning on the controllable switch after receiving a braking signal through a vehicle-mounted bus, comparing supply voltage output by the power supply with a set voltage value, and sending a control signal to the power supply control module when the supply voltage is less than the set voltage value; the power supply control module is connected with the electromagnetic type magnetic track brake and connected to the power supply through the controllable switch, and the power supply control module is used for receiving the control signal, then regulating the supply voltage to be not less than the set voltage value and inputting to the electromagnetic type magnetic track brake; the electromagnetic type magnetic track brake is used for closing a track under the control of the supply voltage so as to brake. With the adoption of the control system and method for the electromagnetic type magnetic track brake, the sufficient braking capacity of the electromagnetic type magnetic track brake is ensured, degaussing can be performed, and the flexible application of the magnetic track brake is achieved.

Description

technical field [0001] The invention relates to the technical field of rail transit vehicle braking control, in particular to an electromagnetic type magnetic rail brake control system and a control method thereof. Background technique [0002] Magnetic rail braking technology is a new type of braking method developed in recent years to adapt to the popularization and high speed of rail vehicles. It mainly relies on the attraction of magnets and rails to generate sliding friction to decelerate rail vehicles. Among them, the electromagnetic type magnetic track brake has the characteristics of large braking force, simple maintenance and convenient operation, and is widely used. The power supply mode of the electromagnetic track brake is directly powered by the catenary or powered by the vehicle battery. [0003] At present, the control method of the electromagnetic track brake on the rail vehicle is under the braking condition, the control unit of the electromagnetic track br...
