摘　　要：针对工业生产中用到的溶剂储液罐液位远程监控的问题,提出采用基于Modbus TCP的现场总线控制结构。Modbus TCP现场总线应用层采用Modbus协议作为通信协议,传输层和网络层采用TCP/IP协议,数据链路层和物理层由以太网实现,所以Modbus TCP具有通用性强和通信速度快的双重优点。设计监控系统结构和I/O点控制算法,编写监控软件,进行系统实验。实验结果表明,Modbus TCP现场总线控制结构能够保证系统具有很高的实时性能,系统结构合理,可扩展性强。In order to solve the problem of remote monitoring of liquid level of solvent storage tank used in industrial production,a field bus control structure based on Modbus TCP is proposed.The Modbus TCP fieldbus application layer uses Modbus protocol as the communication protocol,the transport layer and network layer uses TCP/IP protocol,and the data link layer and physical layer are implemented by Ethernet,so Modbus TCP has the dual advantages of strong versatility and fast communication speed.The structure of the monitoring system and the I/O point control algorithm are designed,the monitoring software is compiled,and the system experiments are carried out.The experimental results show that the Modbus TCP fieldbus control structure can ensure that the system has high real-time performance,reasonable structure and strong expansibility.
