Abstract

The invention belongs to the technical field of laser navigation, and relates to an explosion-proof laser radar navigation device. The device comprises an explosion-proof shell fixedly connected witha radar base, window pipes and a laser radar sensor are installed in the explosion-proof shell, the bottoms of the window pipes are pressed through a pressing ring, and the window pipes are bound to the periphery of the explosion-proof shell through epoxy resin; the laser radar sensor is fixedly installed on a pressing plate, and the pressing plate is fixedly connected to the pressing ring throughan internal grounding device; a wire outlet is formed in the bottom of the radar base; and a cable of the laser radar sensor extends out of a sealing device and a wire pressing joint through the wireoutlet. An explosion-proof laser radar accords with the IP65 sealing level, can adapt to various harsh environments, and avoids influence on safe, reliable and stable operation of the sensor due to short circuit of an internal circuit caused by water input; and via application of the device the, on-site construction intensity and cost are greatly reduced, autonomous three-dimensional scanning modeling can be realized, and accurate arrival at a specific task point can be realized by means of a three-dimensional virtual track.

Description

technical field [0001] The invention belongs to the technical field of laser navigation and relates to laser radar navigation, in particular to an explosion-proof laser radar navigation device. Background technique [0002] Robots or automatic inspection vehicles traditionally use magnetic strips or ribbons to identify and navigate with landmark sensor positioning for autonomous inspection. The cost is low and the accuracy error is large. This method requires on-site laying of tracks and setting of landmark inspection cards, which has the disadvantages of high labor intensity, low efficiency, and long cycle. [0003] The explosion-proof laser radar continuously scans the external environment by emitting high-frequency laser beams while rapidly rotating 16 laser emitting components. After the ranging algorithm provides three-dimensional space point cloud data and object reflectivity, the machine can see the surroundings The world provides strong guarantee for positioning, n...
