摘要:

为增加客车的安全性,提出了一种基于STC89C52单片机同时具有防超载和防撞功能的客车安全系统。通过研究超声波测距原理和脉冲宽度调制原理,并对车身重量和障碍物的距离进行实时监测以实现其功能。对该系统的安全性能和测量精度进行了测试,结果表明,系统达到了设计要求。

关键词: 超声波测距, 单片机, 称重传感器, 脉冲宽度调制

Abstract:

In order to increase the security of coaches,the paper proposes a coach security system with overload 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 distance of the obstacle.Finally,the safety and precision of the system are tested.The experiment result shows that the system meets the requirement.

Key words: ultrasonic ranging;microcontroller;weighing sensor;pulse width modulation
