Abstract

The invention discloses a method and device for determining working range state of an industrial robot. The method comprises the following steps of acquiring a target detection signal of a predetermined range, wherein the target detection signal is a signal obtained by detecting the predetermined range by a millimeter wave transmitting and receiving end; determining first position information of the target detection signal in a tool coordinate system, and converting the first position information into second position information relative to the base coordinate system of the industrial robot, wherein the tool coordinate system and the base coordinate system are coordinate systems established based on the feature information of the industrial robot; and determining the current working rangestate of the industrial robot based on the second position information. The method and device for determining working range state of an industrial robot provided by the invention solve the technical problem of low reliability in the related art for detecting the working range of an industrial robot.

Description

technical field [0001] The present invention relates to the technical field of industrial robot safety detection, in particular to a method and device for determining the state of the working range of an industrial robot. Background technique [0002] At present, all major industrial robot companies attach great importance to the detection of safety conditions within the working range of industrial robots. Due to the complexity of the work site of industrial robots, the different nature of industrial robots, and the great difference in the complexity of the surrounding environment, mainstream security The detection equipment is based on the visual recognition scheme of industrial robots and then added with visual algorithm recognition. However, this kind of scheme is costly, and the accuracy based on visible light feedback signal is low, the algorithm debugging is complicated, and the implementability is difficult. [0003] Aiming at the problem of low reliability of the met...
