现场总线系统在化工物流园区应用

Application of Fieldbus Control System in Chemical Industry Logistics Park

现场总线系统是以测量与控制设备单元作为网络节点,以双绞线、光缆等组成的现场总线为纽带,把位于物流或生产现场具备了智能化、数字化通信能力的测量控制执行设备作为单元,连接成现场总线网络系统,在规定的通信协议下,使多个测量与控制设备之间以及现场设备与远程监控计算机之间,实现数据传输与信息交换,形成适应各种应用需要的自动控制与测量系统。根据现代化工物流园区具有布点分散,连续、连散测量与控制形式多样,控制回路简单等特点,提出了在化工物流园区运用各类常用现场总线系统和实现各类测量控制仪表等组成现场总线网络系统的方法,为区域物流提出了用相对较少的投资,实现智能化、数字化现场控制网络的解决方案。

Fieldbus Control system （FCS） is a network system of measurement and control equipment,as network nodes with the twisted-pair cable, optical cable for bond composed of field bus. Intelligent equipment, digital communication equipment and measurement control device is connected as field bus network system. In the provision of communication agreement, realize the data transmission and information exchange, forming adapt to all applications require automatic control measuring system. According to the modem chemical logistics park with station- ing dispersed, continuous, with even scattered measurement, control various in form, the control system units of sim- ple features, the article proposed composition Fieldbus Control system method that using all kinds of common field bus system and realize various types of measurement and control instrument in chemical industry logistics park, for the regional logistics and put forward the solution, with relatively few investments to realize intelligent, digital scene control network.
