Research on automatic monitoring and early warning technology of operation range based on ultrasonic and Beidou positioning technology
In order to improve operation efficiency and safety and ensure the life safety of operators,an automatic monitoring and early warning technology based on ultrasonic and Beidou positioning technology is proposed.The Beidou real-time dynamic measurement technology is used to receive satellite information in real-time,and the carrier phase measurement and positioning method is used to solve the Beidou positioning,and the specific position of the man-machine is calculated according to the measured satellite-earth distance,satellite and time information.The position and distance of obstacles can be obtained by sending and receiving ultrasonic signals using ultrasonic reflection characteristic to realize collision avoidance detection.The LCD1602 template is used to display the result of man-machine crossing and anti-collision detection,and the buzzer alarm and light-emitting diode are used to send out the dual warning information of sound and light.Experimental results show that when the SNR is 120 dB,the median error of distance measurement between people and vehicles and between vehicles tends to 0.Through this technology can accurately monitor the position of man-machine and collision prevention.
