Study Of The Wireless Multi-Locomotive Synchronic Operation And Control System

With the development of the computer control technology, the Multi-locomotive technology is also under continuously development. According to the basic requirements of Multi-locomotive technology, the Multi-locomotive device should realize these functions such as synchronous commutation, traction, and braking of multi-locomotive, etc. Through the Multi-locomotive device, the driver can control the leading locomotive and the remote locomotive on the leading locomotive, and monitor the operation. It is an important way to realize heavy-load transportation by using the technology of Multi-locomotive and wireless synchronous control system to operate combined train. Bases on requirement of the project of Wireless Multi-locomotive synchronous operation and control system for Cheng Du Locomotive Depot, takes SS3B electric locomotive for research project, aims at problems exists in electric double heading at present, the paper develops multiple traction and wireless synchronous operation and control system instead of the old control mode using cable transmitting signals in order to improve locomotive's traction ability and ensure its' reliable operation.At first, the paper discusses the overall design plan of the wireless synchronization control system, introduces the system's function and system's component modules. In order to improve the reliability of the wireless data transmission, the paper analyzes the several common coding theories and their implementations seriously. Subsequently, the paper presents the system's hardware design, and introduces the wireless transmission module and the interface circuit in detail. Based on the hardware platform, the two kinds of working pattern of this system are analyzed in the paper, the work flow under the two models , the realization of software and the software design of the CAN Bus Interface in the system are also given. Finally, the paper analyzes the system's reliability and the strategies of improving reliability from three respects: the system scheme, the wireless data transmission, and software &hardware methods of anti-interference in the system, gives the experimental verification of the system and summarizing of the achievements.
