The invention discloses a crane electronic fence generation method and system and a crane in the technical field of crane safety, and aims to solve the technical problem that the warning range of an electronic fence cannot be dynamically adjusted according to the actual operation condition of the crane in an electronic fence area due to site limitation. The method comprises the following steps of: acquiring an actual value L of the total length of a boom of the crane under a current boom combination and a maximum distance K between a variable-amplitude hinge point of the boom and a possible rollover fulcrum at the bottom of the crane; calculating the contour radius of the electronic fence according to the actual value L of the total length of the cantilever crane and the maximum distance K; with the rotation center of the crane as the sphere center and the contour radius as the spherical radius, establishing a spherical contour for the target protection area; and determining a closed interval enclosed by the spherical contour and the ground as a detection interval of the electronic fence, and generating the electronic fence. The warning range of the electronic fence can be dynamically adjusted according to the actual operation condition of the crane.

    本发明公开了起重机安全技术领域的一种起重机电子围栏的生成方法、系统及起重机,旨在解决由于场地限制,电子围栏区域不能实现根据起重机的实际作业情况动态调整电子围栏的警示范围的技术问题。其包括:采集所述起重机在当前臂架组合下的臂架总长度实际值L、以及臂架变幅铰点与起重机底部可能的侧翻支点的最大距离K;根据所述臂架总长度实际值L和所述最大距离K,计算所述电子围栏的轮廓半径;以所述起重机的回转中心为球心、所述轮廓半径为球面半径,针对目标保护区域建立球面轮廓;将所述球面轮廓与地面围成的闭合区间确定为所述电子围栏的检测区间,生成所述电子围栏。本发明能够实现根据起重机的实际作业情况动态调整电子围栏的警示范围。
