The invention relates to the technical field of overhead working trucks, in particular to an overhead working truck boom contraction in-place detection method which comprises the following steps: an upper truck and a lower truck are kept in an interlocking state, a boom body freely moves within a limited range, and the lower truck is forbidden to act; the arm body is recovered towards the initial direction; whether the rotary table, the extending arm and the main arm are in place or not is detected and judged through the virtual arm support, if yes, interlocking of the getting-on and the getting-off is relieved, the getting-off action is allowed, if not, the getting-on and the getting-off are kept in the interlocking state, and the reset action is repeated. The method has the beneficial effects that electric appliance elements such as a proximity switch or a travel switch are omitted in arm falling in-place detection of the arm body, a virtual sensor is generated through program logic to replace a real object sensor to achieve interlocking of getting-on and getting-off, the reliability is high, multiple factors such as the extending arm length, the main arm inclination angle and the rotary table rotation angle are comprehensively considered, and the detection accuracy is high. And the accuracy, the reliability and the safety of the whole structure are improved.

    本发明涉及高空作业车技术领域,尤其涉及一种高空作业车臂架收缩到位检测方法,包括以下步骤:上车和下车保持互锁状态,臂体在限定范围内自由活动,下车禁止动作;臂体向初始方向回收;通过虚拟臂支架检测判定转台、伸臂、主臂是否到位,若判定到位,则解除上车和下车的互锁,则允许下车动作,若判定不到位,上车和下车保持互锁状态,重复上述复位动作。本发明的有益效果为:本发明臂体落臂到位检测取消接近开关或行程开关等电器元件,利用程序逻辑生成虚拟传感器代替实物传感器实现上车和下车互锁,可靠性高,且综合考虑伸臂长度、主臂倾角及转台回转角度等多重因素,提升了整体结构的准确性、可靠性和安全性。
