The invention relates to the field of cable cranes, provides an anti-collision early warning method and system for a lifting hook of a cable crane, and aims to solve the problem of poor accuracy and poor timeliness of an existing anti-collision method for the cable crane. The anti-collision early warning method comprises the steps of determining the highest dam section of a cable crane construction dam, the maximum height of the highest dam section from the ground and a first coordinate set of each boundary point of the highest dam section; acquiring second coordinates of the lifting hook in real time, and calculating a real-time height difference between the lifting hook and the highest dam section; respectively calculating distances between the lifting hook and each boundary point of thedam section on an XY plane, and determining the boundary point of the dam section closest to the lifting hook on the XY plane and the corresponding first minimum distance; and when the real-time height difference is smaller than a first preset value and the first minimum distance is smaller than a second preset value, sending early warning information that the lifting hook is about to collide. According to the anti-collision early warning method and system for the lifting hook of the cable crane, the early warning information can be sent when the lifting hook of the cable crane possibly collides with the highest dam section, so that the safe operation of the cable crane is ensured.

    本发明涉及缆机领域,本发明旨在解决现有缆机防碰撞方法存在准确性和及时性较差的问题,提出一种缆机吊钩的防碰撞预警方法及系统,所述方法包括以下步骤:确定缆机施工大坝的最高坝段、最高坝段距地面的最大高度以及最高坝段各边界点的第一坐标集合;实时获取所述吊钩的第二坐标,计算吊钩与最高坝段的实时高度差;在XY平面上,分别计算吊钩与坝段各边界点的距离,确定在XY平面上与吊钩距离最近的坝段边界点及对应的第一最小距离;当所述实时高度差小于第一预设值并且所述第一最小距离小于第二预设值时,发送吊钩即将碰撞的预警信息。本发明能够在缆机吊钩可能将与最高坝段发生碰撞时发送预警信息,保证了缆机的安全运行。
