The invention discloses a control method of a pantograph, belongs to the field of electric locomotive equipment, guarantees the power receiving quality of the pantograph and improves the stability of current, according to the control method of the pantograph, the pantograph comprises a sliding plate, two electric push rods and a controller, and each electric push rod comprises a push rod assembly and a motor assembly. The control method comprises the steps that S10, the initial position difference value of the two push rod assemblies is recorded, and then the two push rod assemblies are driven to act synchronously; s20, a position difference value variable delta pE of the two push rod assemblies is calculated, whether the position difference value variable delta pE reaches a set threshold value pE or not is judged, if yes, the step S30 is executed, and if not, the step S20 is continuously executed; s30, a speed variable delta pT is calculated according to the position difference value variable delta pE, the target speed pT of at least one push rod assembly is calculated according to the speed variable delta pT, and the step S40 is executed; s40, the speed of the push rod assembly is adjusted to be the target speed pT; and S20-S40, circularly executing until the sliding plate is in contact with the overhead line system.
本发明公开了受电弓的控制方法,属于电力机车设备领域,保证了受电弓的受电质量,提高了电流的稳定性,本发明的受电弓的控制方法,受电弓包括滑板、电动推杆和控制器,电动推杆的数量为两个,电动推杆包括推杆组件和电机组件,控制方法包括:S10,记录两个推杆组件初始的位置差值,随后驱动两个推杆组件同步动作;S20,计算两个推杆组件的位置差值变量ΔpE,并判断位置差值变量ΔpE是否到达设定阈值pE,若是则执行步骤S30,若否则持续执行步骤S20;S30,根据位置差值变量ΔpE计算速度变量ΔpT,根据速度变量ΔpT计算至少其中一个推杆组件的目标速度pT,并执行步骤S40;S40,将推杆组件的速度调整为目标速度pT;S20‑S40循环执行至滑板与接触网接触。
