A laser radar with self-checking function

Abstract

The invention provides a laser radar with a self-inspection function, including a laser emitting module, a laser receiving module, a motor scanning module, a self-inspection module, an information recording module, and a control and data processing module; the self-inspection module includes a humidity acquisition unit, an air pressure One or more of the acquisition unit, temperature acquisition unit, voltage acquisition unit, current acquisition unit, motor speed acquisition unit and motor vibration acquisition unit; the control and data processing module is used to judge whether the laser radar is based on the information collected by the self-inspection module If there is a fault, if it is, further judge whether the fault can be solved by adjustment, if it is, control the components of the laser radar to adjust accordingly and send the adjustment to the information recording module for recording; otherwise, control the laser radar to perform power-off protection. The invention can reduce the aggravation of minor faults in the laser radar due to untimely processing, and can also provide data support 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 a laser beam to detect the distance to a target. Lidar can be used to detect the distance, shape and other parameters of stationary objects, and can also be used to detect the shape, speed, angular velocity and other parameters of moving objects. It is widely used in traffic surveys, autonomous driving, robots, surveying and other scenes. Because the lidar has a sophisticated structure and is often used outdoors, and requires long-term operation, it is prone to malfunctions such as abnormal electrical parameters, abnormal motors, and abnormal communications. Because outdoors, minor faults sometimes occur, and because they are discovered or not handled in time, the faults aggravate and even the lidar device is completely damaged, causing great 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
