基于CAN总线的码头岸电监控系统实时性分析

Real time analysis of wharf shore power monitoring system based on CAN bus

随着我国"节能减排"的势在必行,船舶靠港期间使用码头岸电以及岸电供给的智能监控已经成为当前的趋势,并正在大力推广。CAN总线在智能监控领域具有广阔的应用前景,在大型网络监控系统中,监控系统的实时性具有重要的意义。文章分析了CAN总线的实时性问题,针对CAN协议提出了仿真模型,实验测出延时数据,总结比较了当前几种基于TTCAN的算法优化问题。对于开发大型网络监控系统具有一定的现实参考意义。

With the ＂energy conservation and emission reduction＂ become imperative, using of wharf power during the ship is in port and intelligent monitoring of wharf shore power supply have becoming a current tendency,further more,it has being vigorously promoted.The CAN bus has the broad application prospect in the field of intelligent monitoring, in big network monitoring system,the real-time of system is very important. This paper analyse the problem of real-time of CAN bus.The CAN protocol simulation model is proposed.Measuring the delay data of CAN message transmission by experiment. Comparison of several optimization problem based on TTCAN algorithm.For the subsequent development of large network monitoring system have some certain reference significance.
