The Development For Supervising And Controlling System Of The Gate Base On The Profibus

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 modem Hydraulic control technique have developed to a complete automation which include of transmit control testing computer technique, and gradually turn to the digit control and full-automatic control.According to the actuality of the studied water power station, the thesis combine the advanced fieldbus technique, Ethernet and the traditional hydraulic technique together ,and use them to design the supervise controlling system of the water power station.Base on the gate-controlling request of the water power station , designed the gate's hydraulic hoist system. The thesis analyzed the development of the gate's hoist and its controlsystem ,and the localization of the gate's operating machine's traditional hydraulic system , according to today'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 Profibus control and Ethernet technique" , according to that project , completed PLC control procedure and the procedure of the supervise and control( supervise and control software and man-machine interface) , At last the thesis set up a Ethernet network for the monitor and the PLC correspondence of a place of honor machine and PLC and a fieldbus network for the far I/ O mold and the PLC, made the gate supervise and control by network . the network can control the opening , shutting and surveillance the circulate of the eight gates ,which stand in different positions , and make the system satisfied the various requests of that water power station's production, and still guaranteed the system had very advanced at the same time.During the designing of the electricity control system, the thesis used the mode that made up of monitor system and control system, formatted a network that is combined by far concentrates control system and nearly control system .The monitor system chooses the functional monitoring software - the king monitor and the man-machine interface ,which operated conveniently .And the control system chooses dependably programmable logic controller and advance Profibus fieldbus to completely control the spot equipments .Author hopes the thesis's researches can do a little for the development of the water power control technique ,and the combination of the hydraulic technique and the advanced technique, Author also hoping heartily the control technique of the our country develop quickly.
