| Abstract: | A complex automatically control system is built via S7-300 PLC and PROFIBUS, which makes the task of centralized management and decentralized control easy. On the basis of DK8G metro control system, three different schemes had been designed by comparison,in which the redundant PLC control system would be the best. It can reliably fulfill the task of centralized monitor and decentralized control in the metros, with admirable reliability, extensively controlling function and the open field bus standard design. This redundant control system structure will suit to different types of metro, tram, high speed train,inter city and regional train, electric and diesel locomotives. |
