基于单片机的车辆超载系统 Vehicle O verload S ystem B sed O n S ingle C hip M icrocomputer 内容摘要当今社会，在重大的交通事故中，有很大一部分原因是因为超载而引起的。而本论文就是为了降低由于交通事故造成的安全隐患和人们的生命财产安全所设计的一种车辆超载系统。该超载系统需要满足可以对车辆超载进行判断，当车辆发现违规超载时系统发出警报并在 LED 屏幕上显示重量，如果是客车通过计算获得车辆里的人数。该设计是基于 STC89C52 单片机作为系统处理的核心，共两个部分，分别为硬件设计和软件设计，硬件部分使用红外传感器和方向检测电路来记录和评估并进入该系统中的乘客上车和下车。 处理后的数据通过单片机系统发送到 LED 显示器。声光报警装置电路由蜂鸣器和发光二极管组成，继电器用于阻塞总线启动装置。软件部分使用汇编语言编程，并具有模块化结构。 对系统进行调试后，可以更好地完成汽车超载的预警和预警，并控制超载。关键词：智能 超载 单片机 便利Abstract In today's society, a large part of major traffic accidents are caused by overload. This paper is a vehicle overload system designed to reduce the safety hazards caused by traffic accidents and the safety of people's lives and property. The overload system needs to be able to judge the overload of the vehicle. When the vehicle finds an overload violation, the system sends an alarm and displays the weight on the LED screen. If it is a passenger car, it can calculate the number of people in the vehicle.The design is based on the STC89C52 microcontroller as the core of the system processing. There are two parts, which are hardware design and software design. The hardware part uses infrared sensors and direction detection circuits to record and evaluate and enter the system. Passengers get on and off . The processed data is sent to the LED display through the microcontroller system. The sound and light alarm device circuit is composed of a buzzer and a light-emitting dio...
