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 train pipe synchronous control method and system for a heavy-haul combination train. The main implementation process of the method comprises the steps that A, delay time parameters of an instruction, which is transmitted from a master control locomotive to a slave control locomotive, is calculated and verified, and a delay parameter model is established; and B, after themaster control locomotive sends a synchronization instruction to the slave control locomotive, the master control locomotive waits for execution time according to the delay parameter model, and afterthe time of a delay timer is up, the master control locomotive and the slave control locomotive simultaneously execute the target instruction received by the master control locomotive. According to the train pipe synchronous control method and system, through a delay synchronous control strategy, the synchronization performance of the master control locomotive and the slave control locomotive is substantially improved, the problems that vehicle braking synchronization performance is poor and train longitudinal impulse is excessively large due to communication and transfer delay of multiple processing devices are reduced, and the safety of heavy-haul train transportation can be greatly improved.

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...
