Abstract

The invention discloses a control method and a control system for wired electric control air brake. The control method comprises the following steps of when an ECP system is in a running mode, performing a diagnostic test on the ECP system; converting a brake control instruction into a brake cylinder pressure value through brake percentage and sending the brake cylinder pressure value; performing fault diagnosis on the ECP system after a fixed time; if a fault is discovered, sending fault treatment information. By acquiring the brake cylinder pressure value and diagnosing and treating the fault, safe and effective control over a straight-through type brake control technology in different modes is realized, so that the ECP system runs safely and effectively and the running safety of the ECP system is improved.

Description

technical field [0001] The invention relates to the field of control, in particular to a control method and system for a wired electronically controlled air brake. Background technique [0002] With the increase of the length, load and speed of freight trains, the handling of long, large and heavy trains is faced with severe braking problems. [0003] The traditional freight car braking system relies on compressed air to transmit braking commands. Due to the low braking wave velocity, the braking synchronization of different carriages of the entire train is poor, resulting in excessive longitudinal impulse of the train, which affects the safety and efficiency of train operation. [0004] In order to solve the above problems, an ECP wired electronically controlled air braking technology is adopted, that is, the network-controlled straight-through braking control technology. When braking, the train sends braking instructions to all carriages through hard wires and the train ne...
