efficiency and reliability of the controller will decline sharply.
3. Distributed control system (DCS) : Distributed control system (DCS) dominated in the 1980s and 1990s. Its core idea is centralized management, decentralized control, that is, management and control are separated, the upper computer is used for centralized monitoring management function, a number of lower computer decentralized to the site to achieve distributed control, the upper and lower computer with control network
interconnection to achieve information transfer between each other. Therefore, this distributed control system architecture can overcome the defects of centralized digital control system which require high processing ability and reliability of controller. In distributed control system, the realization of distributed control idea is due to the
development and application of network technology, unfortunately, different DCS manufacturers to achieve the purpose of monopoly management and the control of the communication network with their own special closed form, It is difficult to realize network interconnection and information sharing between DCS systems of different manufacturers and between DCS and
