Design of vehicle reversing collision avoidance device based on single chip computer
2009
In order to increase the safety of vehicle reversing, a vehicle reversing collision avoidance device was developed based on single chip computer. The basic principle and the framework of the device were introduced. For the device hardware, the principle of ultrasonic distance measurement was given, the AT89C51 single chip computer was chosen, and the hardware circuits were designed. According to the functions of the device, the system software was designed. The test results show the vehicle reversing collision avoidance device can satisfy the requirement of reverse collision avoidance with maximum measurement distance of 5 meters the minimum measurement distance of 0.2 meters and the error of 5 centimeters.
