基于現(xiàn)場總線與虛擬儀器的車輛監(jiān)控系統(tǒng)

針對多電機監(jiān)控系統(tǒng)信息量大、布線復(fù)雜、調(diào)試不方便等特點，本文介紹了一種基于
現(xiàn)場總線技術(shù)和虛擬儀器技術(shù)的監(jiān)控系統(tǒng)的設(shè)計方案，使用Modbus 協(xié)議與CAN 總線協(xié)議，通過串口總線與CAN 總線的轉(zhuǎn)換，將現(xiàn)場總線技術(shù)和虛擬儀器有機結(jié)合起來，實現(xiàn)了結(jié)構(gòu)簡單、實時性高、擴展性強的多電機蓄電池車輛控制系統(tǒng)。實際使用情況表明本系統(tǒng)，達到了設(shè)計要求。

A Monitor and Control System base on Field Bus and Virtual Instrument Author: Zhu Haizhi, Yang Jianwu, Sun Shuwen Department: Mechatronics Control Laboratory, College of Mechanical Engineering & Applied Electronics Technology, Beijing University of Technology Abstract: To resolve problems of traditional multi-motor monitor/control system, such as excessive information exchange, complex wiring, and inconvenient installation and debugging, this paper provide a design based on field bus and virtual instrument technology. With the help of Modbus protocol, CAN (Control Area Networks) bus, and serial port, combines field bus technology and virtual instrument technology, realizes the convenience, real time, expandability, multi-motor car control system. It goes well in practice and has met the requirements.
