Laser radar having self-check function

Abstract

The invention provides a laser radar having the self-check function. The radar comprises a laser emitting module, a laser receiving module, a motor scanning module, a self-checking module, an information recording module and a control and data processing module, wherein the self-checking module comprises one or more types of a humidity acquisition unit, an air pressure acquisition unit, a temperature acquisition unit, a voltage acquisition unit, a current acquisition unit, a motor rotation speed acquisition unit and a motor vibration acquisition unit, the control and data processing module isused for determining whether the laser radar is in fault according to the information acquired by the self-checking module, if yes, whether the fault can be solved through adjustment is further determined, if yes, components of the laser radar are controlled for corresponding adjustment, the adjustment information is sent to the information recording module for record, otherwise, the laser radar is controlled for power failure protection. The radar is advantaged in that a problem of aggravation of a micro fault caused by non-timely processing existing in the laser radar can be reduced, and data support can be provided for subsequent maintenance and improvement of the laser radar.

Description

technical field [0001] The invention relates to the technical field of laser radar, in particular to a laser radar with a self-checking function. Background technique [0002] Lidar is an electronic device that uses laser beams to detect the distance to an object. Lidar can be used to detect parameters such as distance and shape of stationary objects, and can also be used to detect parameters such as shape, speed, and angular velocity of moving objects. It is widely used in traffic surveys, autonomous driving, robots, surveying and mapping, etc. Because lidar has a precise structure, is often used outdoors, and needs long-term operation, it is prone to failures such as abnormal electrical parameters, abnormal motors, and abnormal communications. Because in the outdoors, sometimes minor failures occur, because the discovery or treatment is not timely, leading to aggravated failures and even complete damage to the lidar device, resulting in huge economic losses.

AI Technical Summary

Problems solved by technology

This method cannot detect the specific information when the laser fails, and cannot provide useful information for later maintenance and improvement, and requires the main control computer to control and record the fault information, which is not practical for the laser radar device used outdoors
