Laser radar full-automatic detection system suitable for intelligent production line

Abstract

The invention discloses a laser radar full-automatic detection system suitable for an intelligent production line. The system comprises a laser radar, an adjustment-free support, an interface conversion assembly, a distance measurement driving module, a data acquisition module, a system control and data center, an electric control translation platform, a laser power test end, a laser pointing testend, a ranging laser receiving end, an analog-digital acquisition I / O assembly, a program control link jumper switch, an optical fiber delay link, a narrow pulse laser signal source, a background light interference source, a double-path program control optical attenuator, a double-path optical fiber combiner, an optical fiber collimator, an electric control rotation and tilting platform and a three-axis motion controller. Spatial distributed automatic measurement of laser power, laser pointing and ranging performance is realized through electric control translation, and laser pointing test iscombined with electric control rotation and inclination to realize self-alignment of laser simulation echo; an optical fiber delay link module is innovatively designed, and one-key full-automatic detection of laser radar performance in different distances, different targets and different environments is realized.

Description

technical field [0001] The invention relates to a laser radar detection system, in particular to a laser radar automatic detection system suitable for intelligent production lines. Background technique [0002] Lidar is the product of the combination of radar principle and laser technology. Using laser as the detection beam, it has a series of advantages such as long range, high sensitivity, high spatial resolution, and strong anti-interference ability. It has broad application prospects in the fields of environment perception and so on. [0003] Both the application demand and output of lidar have seen a blowout development, which makes the lidar industry urgently need to improve the intelligent level of lidar manufacturing, greatly improve production efficiency and increase production capacity. Performance inspection is an essential link in the production process of lidar, and its level of intelligence directly determines the production efficiency and capacity of lidar. ...
