Embodiment 1
[0025] Such as figure 1 As shown, the laser radar sensing lighting system of the present invention includes a laser radar scanning device 1 , a control center 2 and a lighting lamp 3 .
[0026] The laser radar scanning device 1 includes: a laser emitting module 11, which is used to emit pulsed laser light, and sends a signal reflecting the time of pulsed laser light emission to the main control circuit module 21; a laser receiving module 12, which is used to receive the reflected light from the detected area Pulse laser, and send a signal reflecting the time of receiving the pulse laser to the main control circuit module 21; the infrared detector 13 is used to monitor the existence or movement of the human body in the target area through the pyroelectric element.
[0027] The control center 2 includes: a main control circuit module 21, which is used to receive the time when the laser emitting module 11 emits pulsed laser light and the time when the laser receiving module 12 re...
Embodiment 2
[0030] Such as figure 2 As shown, it is a flowchart of the lidar sensing lighting method:
[0031] Step 101, start;
[0032] Step 102, the manager or the user independently sets the range of the scanning monitoring area of the lidar scanning device;
[0033] Step 103, the laser radar scanning device starts scanning work, and sends the scanning data to the main control circuit module; wherein, the scanning data includes: a signal reflecting the pulse laser emission time and a signal reflecting the time of receiving the pulse laser; the main control circuit module is the present With technology, FPGA can be used to control the circuit board;
[0034] Step 104, the main control circuit module receives the scanning data, calculates and obtains the distance information of the monitoring target and sends it to the PLC controller;
[0035] Step 105, the PLC controller receives the distance information of the monitoring target;
[0036] Step 106, the PLC controller judges wheth...
