The invention discloses a getting-on and getting-off interlocking control device and method for an overhead working truck. The control device comprises a supporting leg locking valve, a vertical supporting leg compaction detection travel switch, a lower vehicle controller, an upper vehicle controller, an arm body telescopic length sensor, an arm body variable amplitude angle sensor, a rotary table rotation angle encoder, an upper vehicle multi-way valve set and an upper vehicle unloading valve. The arm body is an arm body of a telescopic arm; the control method comprises the steps that a three-dimensional coordinate value is generated through program logic by means of signals of the arm body telescopic length sensor, the arm body variable-amplitude angle sensor and the rotary table rotation angle encoder, and the three-dimensional coordinate value is compared with a three-dimensional coordinate origin stored in the controller in the vehicle folding state; and a real object detection switch is replaced, so that the automatic interlocking function of getting on and off the high-altitude operation vehicle is realized.

    本发明公开了一种高空作业车的上下车互锁控制装置及控制方法,控制装置包括支腿锁止阀、垂直支腿压实检测行程开关、下车控制器、上车控制器、臂体伸缩长度传感器、臂体变幅角度传感器、转台回转角度编码器、上车多路阀组和上车卸荷阀;臂体为伸缩臂的臂体;本发明的控制方法为,利用臂体伸缩长度传感器、臂体变幅角度传感器及转台回转角度编码器的信号,通过程序逻辑生成三维坐标值,并将该三维坐标值与储存于控制器内的收车状态时的三维坐标原点进行比较,作为该高空作业车上装是否处于收车状态的判断依据,来代替实物检测开关,实现上下车自动互锁功能。
