摘要
分布式控制系统的时间同步问题是一个令人关注的问题 ,传统的硬连线方法增加了系统的复杂性。本文提出了一种基于CAN总线的时间同步设计方案 ,该方法可充分利用CAN总线实时性好、速度快等特点 ,实现实时监测的高度分散性、智能化。最后介绍了在实际应用中基于该方法的测量能够达到的精度。
Many people pay attention to time synchronization in distributed control system. The hard-wired design make the system very complex tradationally. A design method of time synchronization that based on CAN bus was discussed. CAN bus have good real time character and can transmit fast that we can make best use of in the measurement to realize real time measure dispersedly and intelligentized. Finally,the precision of this method was introduced.
