Problems solved by technology

Since the traction and braking control are divided into two control modules, when the braking command is executed through electric-air hybrid braking, the traction control module needs to receive the electric braking force control command sent by the braking control module, and control the traction actuator to perform electric braking. Manual operation, that is, data interaction between the brake control module and the traction control module is req...

Abstract

The invention relates to the technical field of rail transit trains, and specifically relates to a rail transit traction brake fusion control system and a method applying the same. The system includescentral control systems of trailers and traction brake fusion control systems of bullet trains; the central control systems include central controllers; the traction brake fusion control systems include traction brake fusion controllers integrated with traction control modules and brake control modules, and brake executing devices and traction executing devices which are respectively connected tothe traction brake fusion controllers; and the traction brake fusion controllers receive traction or brake instructions sent by the central controllers through a train communication network or receive the traction or brake instructions sent by master controllers from a train hard wire, and respectively control the executing devices to execute traction and brake operation. As a control system canbe integrated through the individual traction control module and brake control module, data transmission between modules can be avoided, and the reliability and accuracy of the system can be enhanced.

Description

technical field [0001] The invention relates to the technical field of rail transit trains, in particular to a rail transit traction braking fusion control system and method. Background technique [0002] The rail transit central control system distributes the traction control system, brake control system, auxiliary power supply system, air conditioning control system, door control system, passenger information system, event recording unit, man-machine interface unit and train automatic driving system through the train communication network. All intelligent units in the whole train are connected into a train network. The train central control system exchanges information with the connected subsystems through the train communication network. [0003] Such as figure 1 As shown, the traditional traction control system and the braking control system have independent controllers. In order to ensure that the brake shoe wear is minimized and the braking response is accelerated du...
