液压绞车自动控嗣系统设计

摘要

At present,most of hydraulic winches adopt open-loop manual control and simple PID closed-loop control method,operation smoothness of the hydraulic winch depends on the driver's experiences,so as to cause low automation degree of the winch and great working intensity for operators.In order to solve the above problems,a kind of automatic control system of hydraulic winch was designed.The system uses coordinated control between single-chip microcomputer and PID controller to adjust speed of the hydraulic winch.The single-chip microcomputer can automatically judge running state of the winch after receiving target speed,and then control opening of hydraulic valve;by splitting the target speed,the single-chip microcomputer can automatically adjust the speed of drum to the target speed with collaborative PID controller,which improves automation level of operation of the winch.The simulation results verify reliability of the system.%目前液压绞车大多采用开环手动控制和单纯PID闭环控制方式,运行的平稳性完全取决于操作人员的经验,造成液压绞车自动化程度低、操作人员工作强度大等问题.针对上述问题,设计了一种液压绞车自动控制系统.该系统通过单片机和PID控制器的协同控制对液压绞车速度进行调节:单片机收到目标转速指令后,自动判断绞车的运行状态,控制各液压阀的开启;单片机通过分割目标转速,协同PID控制器自动将卷筒转速调整至目标转速,从而提高了液压绞车运行的自动化水平.仿真结果验证了该系统的可靠性.
