Abstract
The invention discloses a safe sensing illumination system. The safe sensing illumination system comprises a laser radar scanning device, a control center and an illumination lamp, wherein the laser radar scanning device comprises a laser emission module and a laser reception module, the control center comprises a main control circuit module, a PLC and an alarm prompting module, and the illumination lamp is provided with a current sensor. The invention further discloses an illumination method. The illumination method mainly comprises steps that a distance of a monitored target is acquired through the laser radar scanning device and the main control circuit module and is sent to the PLC, whether a monitored region has a moving object is determined by the PLC according to the distance information, and a start instruction is sent to the illumination lamp when the moving object exists according to a monitoring result; the illumination lamp is conducted to realize illumination; and a work state of the illumination lamp can be monitored in real time through the current sensor. According to the safe sensing illumination system, a problem of noise pollution caused by a sound control illumination lamp can be eliminated, the safe sensing illumination system is convenient and rapid, and management staff or a user can be prompted through the alarm prompting module so as to carry out timely maintenance and replacement of the illumination lamp.
Description
technical field [0001] The invention relates to the application of a laser radar scanning device in a lighting system, in particular to a safe sensing lighting system and method. Background technique [0002] Lidar is a radar system that emits laser beams to detect characteristic quantities such as the position and speed of targets. In terms of working principle, there is no fundamental difference from microwave radar: a detection signal (laser beam) is emitted to the target, and then the received signal reflected from the target (target echo) is compared with the transmitted signal, and after appropriate processing , the relevant information of the target can be obtained, such as target distance, azimuth, height, speed, attitude, and even shape parameters, so as to detect, track and identify the target. LiDAR is widely used in scanning and monitoring the size of target obstacles and the distance between them and other objects, as well as the running speed of target obstacl...
