Research On Anti-collision And Anti-collision Of Ship Lock Warning Device Based On PID Control Algorithm

Ship lock anti-collision warning device is a kind of safety protection device widely used in navigation buildings of water conservancy project.Due to the control mode and electrical equipment failure,the lifting mechanism of the anti-collision warning device of the ship lock is prone to the problem of topping.The problem of topping not only hinders and influences the daily production and maintenance activities of ship lock,but also damages and destroys the lifting mechanism of anti-collision warning device.Therefore,it is of great significance to solve the problem that the lifting mechanism of the anti-collision warning device of the ship lock will rush to the top,reduce the damage rate of the relevant devices of the anti-collision warning device of the ship lock,and improve the safety of the daily production and maintenance activities of the ship lock.Aiming at the problem of ship lock anti-collision warning device topping,this paper establishes the synchronous model of double lifting motors of lifting mechanism,adopts the speed displacement synchronous deviation double feedback cross coupling control method of PID control,solves and analyzes the model,and obtains better control effect.The main work of this paper is as follows :(1)Considering the functional requirements of the lock anti-collision warning device,the control model of double lifting motors is established.Aiming at the asynchronous problem existing in the independent control method of the original lock anti-collision warning device,the cross coupling control strategy is designed to make the double lifting motors run synchronously;(2)Aiming at the singleness of the speed deviation feedback control method,the speed displacement synchronous deviation double feedback control method is introduced to improve the accuracy of the synchronous model control system;Aiming at the overshoot of the original independent control system,the PID control system is introduced to effectively solve the overshoot problem of the double lifting motor.Through the Simulink simulation platform,the independent control model and cross coupled double feedback control model of double lifting motors are built,and the test results verify the effectiveness of the cross coupled double feedback control model;(3)According to the actual control environment requirements of the lock anti-collision warning device,the control strategy is further optimized to solve the problem of topping.In view of the factors that may lead to the problem of topping in the original lock anti-collision warning device,such as the installation position of the limit device,the device type and the wiring mode,the equipment control and wiring control are updated and optimized,The experimental results verify the control effect of the optimal control strategy.
