摘　　要：介绍了原有的连续运输系统串行通信网络结构及主站通信流程,指出原有通信网络中存在总线通信效率低、从站的通信故障可能导致整个网络瘫痪的问题,提出了一种改进的连续运输系统串行通信网络。改进的通信网络将原有通信网络分成2个并行的通信网络,通过减少通信访问量、提高波特率、改变通信差错控制方式等方法,有效解决了各种通信矛盾。实际应用表明,改进的通信网络运行可靠、响应及时,提升了连续运输系统的可靠性。The paper introduced structure and communication flow of main station of original serial communication network of continuous conveying system,indicated that problems of low bus communication efficiency and communication fault of slave station in the original communication network would lead to network paralysis,and proposed an improved serail communication network of continuous conveying system.The improved communication network divides the original communication network into two parallel communication networks,and uses methods of reducing communication access amount,improving baud rate and changing communication error control mode to solve various communication contradictions.The actual application shows that the improved communication network has reliable running and timely response,and promotes reliability of continuous conveying system.
