Abstract


With the rapid development of power electronics and computer control technology , electric locomotive control technology has been tremendous progress , with microcomputer control technology as the core of a new generation of control technology . Due to the rapid development of microprocessor technology and a variety of fieldbus technology , makes it possible to distributed control technology applications in the computer control system . Traditional relay control circuit due to their own defects has been difficult to meet the needs of the modern electric locomotive control system . Therefore , in order to improve the the locomotive control performance , improve the reliability of locomotives running , This paper presents the design of electric locomotive based on CAN bus technology and fault-tolerant technology logic control unit (LCU) . The article elaborated LCU structure , the main components of the workflow , and characteristics of binding CAN2.0B agreement to develop a able to fully meet the system requirements , the higher the efficiency of communication protocols . Finally, in the analysis system fault tolerance at the same time , the introduction of the reliability evaluation index of the system was evaluated .
