Abstract

The invention provides a traction and braking fusion system based on a two-stage control architecture, which comprises the following steps: when a first-stage control host has a control right, receiving a network signal, and distributing traction force or braking force of a whole train according to the network signal; or when the second-level control host has the control right, the hard wire signal is received, and the traction force or the braking force of the vehicle is calculated; then, according to the impact rate limitation, the traction target value of each period is sent to the ICM through the vehicle network; or the target value of the electric braking force is sent to the ICM through the vehicle network; or the target value of the electric braking force is sent to the ICM, and the target value of the friction braking force is sent to the APM; the ICM collects actual traction force, or the ICM collects actual electric braking force, or the ICM collects actual electric braking force, the APM collects actual friction braking force, and the actual traction force, the actual electric braking force and the actual friction braking force are sent to the first-stage control host or the second-stage control host; and the first-stage control host or the second-stage control host is enabled to perform force distribution again.

Description

technical field [0001] The invention relates to the technical field of fusion control, in particular to a traction braking fusion system and method based on a two-level control architecture. Background technique [0002] At present, the traction braking system of rail transit vehicles is relatively independent. The traction management control of the vehicle is handled in a distributed manner by the traction controllers of each vehicle, and the braking management control of the vehicle is handled in a distributed manner by the brake controllers of each vehicle. In the process, the train management and control system (Train Control and Management System, TCMS) only undertakes the limited information transmission function, and does not realize the information sharing among the systems and the centralized management of the traction braking of the whole train. The links are long and the coordination between systems is poor, resulting in weak vehicle control performance, fluctuati...
