BRAKE INSTRUCTION CONVERSION AND CONTROL CIRCUIT FOR MULTIPLE UNIT

摘要

A brake instruction conversion and control circuit for multiple units comprises a vehicle circuit interface, a brake instruction conversion device, a brake control device and a locomotive coupler. The vehicle circuit interface and the brake instruction conversion device are connected with 5 data transmission lines respectively used to output a traction valid command, brake valid command, ATO valid command, locomotive rescue command and multiple-unit rescue command to the brake instruction conversion device from the vehicle circuit interface. The brake instruction conversion device is further connected to brake relays from levels 1-7, and the brake relays from levels 1-7 are connected to the brake instruction conversion device via respective data transmission lines. The locomotive coupler is connected with brake train lines from levels 1-7, and the brake train lines from levels 1-7 are connected to the brake control device. In the present invention, a DC voltage of 3-8 V outputted from a master controller is divided into 7 levels respectively corresponding to braking from levels 1-7, thus realizing hard-wired instruction backup and allowing cooperation with a mature braking system for multiple units.
