基于流量计算的PLC一体化流量测量方法的改进

PLC integration based on improved traffic flow measurement method to calculate the

流量计算模块的使用最主要的目的就是能够有效和PLC之间的无缝通信。很多的PLC都能够有效支持以太网TCP/IP通信和很多串行协议。一旦在处理器上生成了流量信息,利用网络就能有效对这些信息进行访问,另外数据采集、远程SCADA、HMI以及历史和维护应用系统也可以对这些信息进行访问,最终就能够有效形成一个灵活经济的通信机制。本文主要就对基于流量计算的PLC一体化流量测量方法的改进进行了分析。

The use of flow calculation module of the main purpose is to be able toseamless communication between the effective and PLC. A lot of PLC caneffectively support the Ethemet TCP/IP communication and serial protocol. Once in the processor generates a flow of information, the network can effectively on these information access, and data acquisition, remote SCADA, HMI as well as the history and maintenance of application system can also access to such information, and ultimately will be able to effectively form a flexible and economiccommunication mechanism. This paper mainly analyzes the improvement of PLCintegrated flow measurement method based on flow calculation.
