Abstract

The invention discloses an EPCU(electric pneumatic control unit) backup conversion device of a CCB II (computer controlled brake-second generation) brake. The EPCU backup conversion device comprises a power source conversion module, a signal control acquisition module, a signal control output module, bus expansion, a control module, an LON (local operating network) module, FTT(free topology transceiver)-10A LON transceivers, double-port RAM(random access memory) and MVB(multifunction vehicle bus) communication chips, MVB network data transceivers, and a default indication storage module. By the EPCU backup conversion device of the CCB II brake, a solution for assisting vehicle due to EPCU partial default (such as default codes 014, 017, 025 and the like) is provided, a locomotive brake command is ensured to be executed normally and locomotive normal running is maintained.

Description

technical field [0001] The invention relates to an EPCU backup conversion device of a CCBII braking machine. Background technique [0002] EPCU (Electro-Pneumatic Control Unit) is the executive part of the CCBII brake, which is installed at the end of each locomotive to generate precise train tube and brake cylinder pressure. EPCU is composed of 5 intelligent nodes (ERCP, BPCP, 16CP, 20CP and 13CP), 2 pure air components (BCCP, DBTV) and 1 voltage conversion module (PSJB), and receives EBV through the LONWORKS network (main control / stand-alone mode) or IPM (in slave mode) braking command. [0003] EPCU adopts a modular and intelligent design method, and its five intelligent node LRUs have certain self-diagnosis capabilities. Among all 35 EPCU fault codes, 10 faults can continue to operate in the main service, 13 faults must be switched to backup mode, and 12 faults (such as fault codes 014, 017, 025, etc.) need to be switched Up to 34% of the total EPCU failures. The swi...
