Problems solved by technology

The traditional braking system of freight wagons relies on the compressed air of the electropneumatic braking system to transmit braking commands. Due to the low braking wave velocity, the braking synchronization between the vehicles that constitute the wagon formation is poor, resulting in the longitudinal impact of the wagon formation during braking. If it is too large, the safety and braking efficiency of the wagon marshalling will be greatly reduced

Abstract

The invention discloses a control method and device for switching of wired electric control air brake and electric pneumatic brake. When a switching request for switching a train brake system between a wired electric control air brake system and an electric pneumatic brake system is received, brake force is applied to a train at first, and braking force is kept in the switching process, so that the train braking effect can be kept in the switching process, stability of switching of braking control power between the wired electric control air brake system and the electric pneumatic brake system can be ensured, and safety switching between the fired electric control air brake system and the electric pneumatic brake system can be achieved.

Description

technical field [0001] The invention relates to the field of control technology, in particular to a control method and device for switching between wired electronically controlled air braking and electropneumatic braking. Background technique [0002] Heavy-duty transportation technology has been recognized internationally as the direction of railway freight development. Heavy-duty transportation requires the use of heavy-duty trains. Heavy-duty trains are super-long and overweight heavy-duty freight trains that are driven by two or more machines. . On transportation lines with concentrated freight volume, heavy-duty trains are usually used to form large-scale special-purpose freight car formations with large vehicle load capacity and a large number of trains to meet the needs of heavy-duty transportation. [0003] As the length, load and speed of the wagon formation increase, the wagon formation is faced with severe braking problems when manoeuvring. The traditional braki...
