摘　　要：当今的工业控制已从集中监控、集散控制进入网络时代,如何实现各种不同设备之间的通信已成为系统的关键所在。对吐哈油田销售事业部远程监控系统进行了研究,重点分析了系统的通信结构、通信协议和软件的编程组态,并提出了利用已有的网络和Modbus协议实现不同系统间远程实时监控的思路。基于网络和Modbus协议的远程监控系统为现有系统的互联提供了借鉴,具有广阔的推广应用前景。At present, industrial control has paced from centralized control and distributed control into network era. Implementing communication among various different devices is the critical issue in forming a system. The remote monitoring and control system in Marketing Department of Tuba Oilfield is researched, and the communication structure, communication protocols and software programming and configuration are analyzed emphatically. The concept of adopting existing network and Modbus protocol to implement real-time remote monitoring among different systems are proposed. The remote monitoring and control system based on network and Modbus protocol is a good reference for interconnecting existing systems and possesses wide applicative prospects.
