The traditional laser detection control system control by reconstructing the equivalent Chirp technology reconciliation algorithm. The detection process is too rigid,the laser scanning process fluctuates greatly,and the accuracy of the measurement control results is low. The laser detection control system based on the Internet of Things technology is designed. Its overall framework includes the system application layer,the network transmission layer and the physical perception layer. The laser signal detection module is used to separate the same laser light source,improve the detection flexibility,determine the current operating state of the control system through different signal processing processes,and carry out laser signal detection;The digital signal processing module is used to complete the comprehensive processing of laser signal. System software design programmable controller workflow,the internal tasks of the system to carry out circular processing,the establishment of a laser scanning test mathematical model,ensure the uniform speed of laser scanning process. The experimental results show that the expected results of the functional test of the designed system are all consistent with the actual results,the average laser power is 4322. 9 W,and the laser detection control error is 2. 37 %,indicating that the system can carry out stable and high-precision laser detection control.
