| Abstract: | In order to advance the working dependability and automatization degree, on the base of original system, a plan of controlling flood discharge gate by the water level signal with PLC and frequency control of motor speed technology is put forward, and the working principles and the logical process of this system, and the overall design and the design of autocontrol system are presented. The programme of control system has been edited and debugged, and the system has run successfully, the project of system is proved to be feasible, simple and easy to be realized. The method is general, can be used to control gate widely. |
