nd more notable in the field of puter39。 s centralized and separated control. The fieldbus features: 1. Fast and realtime 2. Open, manipulate and alternate usable 3. The functional independency of the locale equipment39。 s intelligence. 4. The highly decentralization of system structure 5. The strong antijamming At present, the most popular fieldbus in the world is based on OST model, Including physical layer, data link layer, application layer and etc. The FF, Profitbus, HART, CAN and LonWork are the most effective ones on this field. Profitbus, proposed by SIEMENS, is based on IS07498, which refers to OSI (open system interconnection) model and defines the specialty of physical transmission, protocol of bus wire39。 s storage and extraction, as well as application function. This bus wire connect the longdistance equipments in system and control equipment of other manufacturer. Especially, the adoption of control word used in munication and control reduced the quantity of control cable, also. The good treatments of grand and protection has an every strong capability of anti jamming. With the scale of social production extends and the production horizontal exalts, the electricity control technique and the Hydraulic technique all develop very quickly. Electricity control technique developed from the relay system to the direct digit control ( DDC) system、 the disperse control system( DCS) to the fieldbus control system (FCS).The modern Hydraulic control technique have developed to a plete automation which include of transmit, control、 testing puter technique, and gradually turn to the digit control and fullautomatic control. According to the actuality of the studied water power station, the thesis bine the advanced fieldbus technique, Ether and the traditional hydraulic technique together ,and use them to design the supervise controlling system of the water power station. Base on the gatecontrolling request of the water power station， designed the gate39。 s hydraulic hoist system. The thesis analyzed the development of the gate39。 s hoist and its control system ,and the localization of the gate39。 s operating machine39。 s traditional hydraulic system， according to today39。 s control technique, especially the characteristics of the Profibus fieldbus， the thesis put forward the project that the gate supervise controlling system base on the Profi。
