Laser navigation unmanned trolley for intelligent logistics and navigation method thereof

Abstract

The invention discloses a laser navigation unmanned trolley for intelligent logistics. The laser navigation unmanned trolley comprises a trolley body, a walking mechanism and a laser navigation mechanism, wherein the laser navigation mechanism comprises a first support, an H-shaped connecting rod, a deflection support, an elastic deflection driving assembly and a laser transceiver, the laser navigation mechanism further comprises a plurality of reflection units, the section of each reflection unit is a right triangle, two right-angle surfaces of each reflection unit are both coated with a total reflection coating, the upper half part of the inclined surface of each reflection unit is provided with a gradual change light blocking layer, and the attenuation effect of the gradual change light blocking layers is linearly enhanced in the Y direction; and every two adjacent reflection units are arranged in a central symmetry mode, the included angle between the bevel edge and the bottom edge of each reflection unit with the inclined surface facing the same direction is gradually reduced in the X direction, and a one-way light-transmitting coating is arranged on the gradual change light blocking layer. Autonomous navigation of the trolley is achieved, the running posture of the trolley is obtained, the problem that the navigation precision of the trolley is reduced or even interrupted due to the fact that a reflector is shielded or shifted is solved, and the environment adaptability of the trolley is improved.

Description

technical field [0001] The invention relates to a laser-guided unmanned car for intelligent logistics. Background technique [0002] At present, the laser navigation unmanned car used for intelligent logistics needs to set a reflector in the vertical space around the moving path of the car during navigation; however, in actual application scenarios, the reflector used as the reference for car coordinate correction is often affected by the cargo on the ground Occlusion or impact displacement and other reasons cause the navigation accuracy of the car to decrease or even interrupt the navigation, which reduces the car's ability to adapt to the environment. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings, and provide a laser-guided unmanned car for intelligent logistics. [0004] To achieve the above object, the specific scheme of the present invention is as follows: [0005] An unmanned car with laser n...
