A rail vehicle tread modification control method, comprising the following steps: integrating an electronic control unit and an air circuit control unit; when the rail vehicle is running, the electronic control unit is embedded with a running sensor to identify the running state of the rail vehicle ; The air path control unit is used to monitor the real-time working pressure of the tread modifier; through the control signal, the gas path control unit is automatically controlled to inflate, maintain pressure or exhaust, and then control the rail vehicle tread modifier according to the target pressure action. The present invention also provides a rail vehicle tread modification control device for implementing the method, and a rail vehicle tread modification control system using the rail vehicle tread modification control device. The invention solves the problem of how to automatically control the tread modification of rail vehicles based on the running state, improves the degree of automation and intelligence, and improves work efficiency. At the same time, the fault-oriented safety loop design and manual / automatic mode improve the safety and availability of the system.
Description
technical field [0001] The invention belongs to the technical field of rail vehicle measurement and control, and relates to a rail vehicle tread modification control system. Background technique [0002] The tread shaper is a device that removes oil, rust and other impurities on the tread surface and regulates the shape of the tread during the operation of the rail vehicle, so as to improve the adhesion coefficient between the wheel and rail, reduce the probability of wheel locking and sliding, and reduce the braking force. The purpose of improving ride comfort. [0003] At present, most of the control methods for rail vehicle tread modification adopt open-loop control based on the rail vehicle's own braking signal, which is specifically reflected in: 1) Obtaining the rail vehicle's own braking signal needs to be transmitted through the network or hard wire, which increases the The uncertainty of communication and the complexity of the system have the problem of low reliabi...
