Design and Implementation of Laser Warning Testing System Based on Wireless Control

The traditional laser warning testing system has the problems of low angle testing efficiency, poor coding accuracy, low security and inconvenience. For these problems, a design scheme of a laser warning testing system based on wireless control is proposed. The corresponding deflecting angle of the warning unit is controlled through wireless remote control mode, so the signals with different patterns is emitted from the laser, and the warning characteristics testing of the laser warning unit is completed. The programmable timer array(PCA) software timer mode inside the STC microcontroller is used to improve the accuracy of the pulse timing, and the wireless remote control is used to turn the laser on and off. The applications show that the design scheme has the advantages of convenience in testing and operation, and the testing efficiency and safety are improved.
