The invention relates to the technical field of control systems, and provides an aerial work platform and a safety control method and device.The safety control method of the aerial work platform comprises the steps that it is determined that the aerial work platform is located at an upper limiting position or a lower limiting position; acquiring a first angle value corresponding to the upper limit position of the fork frame, and taking the first angle value as an upper limit calibration value; or acquiring a second angle value corresponding to the lower limit position of the fork frame, and taking the second angle value as a lower limit calibration value; the current angle value of the fork frame and the current inclination angle value of the chassis are obtained; according to the current angle value of the fork frame and the current dip angle value of the chassis, the angle compensation value of the work platform is determined, and according to the difference value between the angle compensation value and the upper limiting calibration value or the lower limiting calibration value, the limiting position of the work platform is determined. The device can replace a limiting structure or a limiting switch for limiting, operation is more intelligent, reliability is high, fault alarm caused by clamping stagnation of the stroke switch can be prevented, and the operation cost is saved.
本发明涉及控制系统技术领域,提供一种高空作业平台、高空作业平台的安全控制方法及装置,该高空作业平台的安全控制方法包括确定作业平台处于上限位位置或下限位位置;获取叉架在上限位位置对应的第一角度值,并将第一角度值作为上限位标定值;或获取叉架在下限位位置对应的第二角度值,并将第二角度值作为下限位标定值;获取叉架的当前角度值以及底盘的当前倾角值;根据叉架的当前角度值和底盘的当前倾角值,确定作业平台的角度补偿值,根据角度补偿值与上限位标定值或下限位标定值的差值,确定作业平台的限位位置。本发明可代替限位结构或限位开关进行限位,操作更加智能化,可靠性较高,可防止行程开关卡滞导致故障报警,以节约运行成本。
