Vehicle positioning method and system based on wired electronically controlled air brake ecp system

Abstract

The invention discloses a vehicle locating method and system based on a wired electronic control air damping ECP system. All vehicles to be located in a truck group have access to the ECP system one by one according to the random access sequence, and when any vehicle to be located has access to the ECP system, whether current pulses are detected or not is judged; when the current pulses are detected, one is added to the current pulse count value of the current vehicle having access to the ECP system on the basis of the current pulse count value of the last vehicle having access to the ECP system; when no current pulse is detected, the current pulse count value of the current vehicle having access to the ECP system is made to be equal to that of the last vehicle having access to the ECP system; after all the vehicles to be located have access to the ECP system, all the vehicles to be located can be accurately located according to the number of all the vehicles to be located and the current pulse count value of each vehicle to be located.

Description

technical field [0001] The invention relates to the field of control technology, in particular to a vehicle positioning method and system based on a wired electronically controlled air brake ECP system. 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 truck formation braking ...

AI Technical Summary

Problems solved by technology

The traditional truck formation braking system relies on compressed air to transmit braking commands. Due to the low braking wave velocity, the braking synchronization between the vehicles that make up the truck formation is poor, resulting in excessive longitudinal impact of the truck formation during braking, which will cause The safety and braking efficiency of wagon marshalling is greatly reduced
