Study And Design Of Remote Control System For Gate Open And Close Of Spill Dam

Due to the need to defend against floods and shipping power generation,water Conservancy projects in rivers and reservoirs and dams have built and used Gates.With the rapid development of the social economy and the continuous improvement of the function of the computer monitoring system,"no one on duty and few people on duty" has become an inevitable requirement for remote centralized control of the gate.Based on the problems existing in the existing gate control system of overflow dam,this paper studies the current situation of remote computer monitoring system of gate opener at home and abroad.A remote control system for overflow dam Gates is designed and implemented through the study of remote operation control processes,data acquisition methods,visual audio subsystems,security state analysis,fault identification and rapid processing,and remote fault diagnosis.The system performance is tested and analyzed.This thesis carries on the detailed argumentation research in the following aspects.(1)This paper analyzes the fault of existing gate control system,and studies and designs the structure and function model of overflow dam remote control system.(2)according to the system structure and functional requirements,by using frequency conversion soft start control,designed and realized overflow dam remote control system,by adopting the star redundant Ethernet network structure to improve the system internal communication efficiency,as well as system reliability.(3)The design of the remote monitoring system of the gate computer is carried out,and the function of each sub-function module of the system is analyzed in detail.(4)The test results show that the system network has good openness and extensibility.The system has high reliability due to the adoption of star redundant network structure.(5)According to the target management requirement of "no duty,few people are on duty" in water Conservancy gate management,this paper explores and studies the control of gate opener by computer remote monitoring system,and satisfies certain target requirements to reach the expected effect.Finally,This paper also analyzes and summarizes the shortcomings and possib le problems in the system,and puts forward the trend of future development.
