Research And Design For The Logical Control Unit Of Electric Loco Motive

In recent years, with the quick development of microelectronics and network techniques, Electric locomotive control technologies are being greatly improved unceasingly, making the distributed system controlled by mil- microcomputer. On the base of research for the fault of traditional relay control circuit in electric locomotive, this article offers a soft-controlled way for the system with the application of single chip microcomputer. Combining the working environment of Electric locomotive and the characteristics of the in general Programmable Logic Controller, the system design will become the software for whole control logical function. The hardware of control system applies distributed design and the structure with microcomputer + Complex Programmable Logic Device. The system constructs a data communication network for the realization of information synchronous. Lastly, this article introduces anti-interference measures in the system design.
