| Abstract: | In order to increase the security of coaches, the paper proposes a coach security system with over- load prevention and anti-collision based on single-chip microcontroller STC89C52. The design is realized by studying the principle of ultrasonic ranging and pulse width modulation and monitoring the weight of the vehicle and the dis- tance of the obstacle. Finally, the safety and precision of the system are tested. The experiment result shows that the system meets the requirement. |
