Abstract

The invention discloses a laser radar automatic detection system suitable for an intelligent production line, including a laser radar, an adjustment-free support, an interface conversion component, a distance measurement drive module, a data acquisition module, a system control and data center, and an electronically controlled translation Taiwan, laser power test end, laser pointing test end, ranging laser receiver, modulus acquisition I / O components, program-controlled link jumper switch, optical fiber delay link, narrow pulse laser signal source, background light interference source, Dual path control optical attenuator, dual fiber beam combiner, fiber collimator, electric control rotation and tilt table and three-axis motion controller. The invention realizes the spatially distributed automatic measurement of laser power, laser pointing and ranging performance through electronically controlled translation, and combines the laser pointing test with electronically controlled rotation and tilt to realize the self-alignment of laser simulated echoes; the innovative design The optical fiber delay link module realizes one-button automatic detection of lidar performance in different distances, different targets and different environments.

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. ...
