Design of integrated cross-line training device based on distance measurement and sensing
The experimental device is composed of closed laser beam ring formation,distance sensor characteristic test,application training and power supply unit.The laser produces a double right-an-gled red laser beam,and adjusts the 2 planar mirrors to form a closed cordon.Using infrared,ultra-sonic and laser ranging sensors,the analog signal is output,the test spacing is changed,and the"dis-tance-voltage,distance digital tube and LCD screen display"test is performed.Pressure,infrared and ultrasonic distance sensors transmit the acquisition signal to the microcontroller for processing and inter-pretation.The feedback signal controls the optocoupler and solid-state relay,drives the steering gear,stepper motor,LED light and voice module,and performs actions such as"running a red light-fall-ing blocking bar","hand off the steering wheel-brake wheel","crossing the 1m spacing line-bright LED flashing red light"and voice warning.This experimental device has the characteristics of modularity,strong operability and rich teaching content,and has broad application prospects.
