Embodiment Construction

[0034] The main realization process of the present invention is as follows:

[0035] (1) First, judge whether the locomotive brake is in the running position. If it is the running position for air charging, set the target value of air charging higher than the constant pressure value of 600kPa, and set the target value of 607kPa to eliminate the relay valve hysteresis and cause the train to The pipe pressure cannot reach the target pressure value of 600kPa.

[0036] (2) After the air filling at the operating position is completed, record the pressure of the balanced air cylinder of the brake and the pressure of the train pipe, calculate the difference between the pressure of the balanced air cylinder and the pressure of the train pipe, and obtain the hysteresis parameter of the relay valve of the locomotive brake. The master locomotive transmits the hysteresis parameter value of the relay valve of the master locomotive to the slave locomotive through wireless, and the slave loc...

Abstract

The invention discloses a method and system for synchronous control of train tubes of a heavy-duty combined train. The main implementation process of the method includes: A. Calculating and verifying the delay time parameters of the command transmission from the master locomotive to the slave locomotive, and establishing a delay parameter model; B. After the master locomotive sends a synchronization command to the slave locomotive, the master locomotive waits for the execution time according to the delay parameter model. After the delay timer expires, the master locomotive and the slave locomotive simultaneously execute the target command received by the master locomotive. The present invention greatly improves the synchronization performance of the master locomotive and the slave locomotive through the delay synchronization control strategy, and reduces the problems of poor vehicle brake synchronization performance and excessive train longitudinal impulse due to communication and multiple processing device transfer delays. Problems, can greatly improve the safety of heavy-duty train transportation.

Description

technical field [0001] The invention relates to the technical field of braking control of railway heavy-duty locomotives, in particular to a method for synchronous control of train tubes of heavy-duty combined trains. Background technique [0002] The world's railways have developed rapidly under the theme of "heavy-haul freight, high-speed passenger transportation", and heavy-haul transportation technology has been internationally recognized as the direction of railway freight development. However, with the increase of the length, load and speed of the wagon formation, the handling of long and heavy-duty trains is faced with severe braking problems. The traditional truck braking system relies on compressed air to transmit braking commands. Due to the low braking wave velocity, the synchronization of the braking of each vehicle is poor, resulting in excessive longitudinal impulse of the train, which affects the safety and operating efficiency of the train. [0003] For dome...
