Decentralized control system for layering controller

The invention relates to a decentralized control system for layering a controller. The traditional controller arranged in a plane layout manner is divided into a plurality of layers to ensure that a plurality of tasks completed by one control unit set in an original DSC (Decentralized Control System) are respectively executed by a plurality of FCUs after the function is subdivided and coordinatedby using an MCU (Microprogrammed Control Unit), thus the correspondence of the control unit and equipment is more clear, the load factor of data transmission on a backbone network is effectively reduced, the control risk is dispersed and the response speed is increased. Because the FCUs controlled in device level are placed at a site of an equipment side, the length of a cable connecting the siteequipment is reduced, and the function of realizing PID (Proportion Integration Differentiation) regulation is realized in stead of the traditional intelligent apparatus; and the site equipment is always measured by adopting conventional apparatuses. According to the invention, industrial Ethernet transmission is adopted in longer distance between the site FCUs and the MCU in a control chamber, compared with the original DCS with same control scale and distance, the control cable cost can be saved by above 60 percent, the investment cost of the site equipment is lowered, the area of the control chamber is effectively reduced, and the cost is greatly decreased.
