摘　　要：在传统手动控制拖拉机提升机构的基础上进行设计改造,阐述了基于ARM控制器的PWM信号经隔离、放大电路处理后,对液压系统中的电磁阀实现通断控制,从而实现拖拉机提升机构的电液控制。主要包括电液提升机构的总体设计、ARM控制器信号控制、放大模块、电磁阀控制、液压改造以及Multisim系统的仿真实验。仿真实验表明电液控制提升机构的设计是有效的。Design and renovate based on the traditional Manual control of the tractor hoisting mechanism, expound the PWM controlled by the ARM controller treatment though the isolation amplifier circuit, realize on-off control by regulating solenoid valve in the hydraulic sys- tem, so as to realize the Hoisting Mechanism of tractor with the Electric-hydraulic control. Mainly include the overall design of the Electric- hydraulic Hoisting Mechanism, Signal control with ARM, Amplification module, Solenoid valve control, Hydraulic transformation and Simula- tion experiment of the system by Multisim. Simulation results show that the design of Electric-hydraulic Hoisting Mechanism is effective.
