基于分布式结构的教学型物流系统研制

Research of logistic system for teaching activities based on distributed structure

介绍基于三级分布式测控网络框架开发的教学型物流系统,采用了CAN、Ethernet、RS232等网络总线,该系统由PC、IPC、PLC组成。给出了多机通讯软件的设计方法,针对不规则的分布式网络结构,对通讯路径算法作了探讨。

A distributed automatic logistic system for teaching activities is introduced,a three layers network is established by field-bus CAN,Ethernet and RS-232. The system is consisted of PC,IPC and PLC. Also gives an account of the muhi-communition software. To irregular topology in distributed network ,algorithm about communication path is discussed.
