浅谈现场总线及现场总线控制系统

Elementary Introduction of Field Bus and the Control System of Field Bus

现场总线技术是一种集计算机技术、通信技术、集成电路技术及智能传感技术于一身的新兴控制技术。现代工业控制思想的核心是：控制功能进一步分散化，以体现“控制分散，危险分散”的设计思想，因其可在测量数据的基础上完成对工业过程的控制，使控制的危险进一步分散，从而满足现代化生产对工业控制日益提高安全性的要求。

Field bus is a new kind of technology which accumulates computer technology, communication technology and intelligent sensor technology together. According to the idea of modem industrial control theory, control function should be more distributed, and so the design idea of'the more distributed the control, the less the danger' will be arrived. In the filed bus control system, the control is performed basing on data measuring and the danger of control becomes more distributed. Therefore, it can meet the safety demands of control which modem industrial production needs.
