【摘要】：迅速发展的国家经济,稳步提高的生活水平,给我们带来越发广阔的活动范围、以及日益多元化的出行方式。但是在交通给我们带来便利的同时,安全隐患也随之而来。从国家统计局数据看出,全国范围内在2014年一共发生了196812起大小不等的交通事故,58523人数因此罹难,211882人在事故中受伤。而当车辆超载时,路面的负担将不可避免的增加,根据统计显示,全国每年有超过300亿元的损失是单纯由于货车超载所造成的,这对国家的财政是一笔很大的损失。引起这些事故的原因有很多,比如:路面环境、司机技术及状态、行人以及道路状态这些都是交通事故诱发的主客观因素。但是,另一项统计表面,在货车发生的交通事故中,有超过百分之八十的几率是因为超载。本设计就从监管手段入手,出于对车辆货物的安全性研究,通过技术手段干预来达到减少交通事故的发生率。本文研究货车超重控制系统,系统地阐述大型货车超载的产生以及发展,监测大型货车的超载系统的原理和技术,需要对承重量很大的货车运输进行均载全过程检测,可确定货车是否超重并在货车超重的时候提供报警行为。STC89C52单片机,就是为本设计的中心处理器,而称重传感器WPL110会将重量信号转化成电压信号,然后A/D转换芯片TLC0838会再次将其转换成数字信号,就可以很容易得出货车的实际重量,然后实际重量会通过RS485接口传输到上位机,然后系统会自动将测得重量与设定重量进行对比,就能很容易判断货车是否超重,如果超重就会发起警报,并且,同时显示出其超重重量。
[Abstract]:The rapidly developing national economy and steadily improving living standards have brought us a wider range of activities and increasingly diversified modes of travel. But while transportation has brought us convenience, The security risks also followed. According to the National Bureau of Statistics, a total of 196812 traffic accidents of varying sizes occurred nationwide in 2014, resulting in the deaths of 211,882 people. And when the vehicles were overloaded, The burden of the road surface will inevitably increase. According to statistics, more than 30 billion yuan of losses in the country each year are caused solely by overloading of trucks, which is a great loss to the state's finances. There are many reasons for these accidents. For example, road environment, driver's technique and condition, pedestrian and road condition are all subjective and objective factors induced by traffic accident. The odds are more than 80% because of overloading. This design starts with regulatory measures to study the safety of vehicle cargo. In this paper, the overloading control system of freight cars is studied, the generation and development of overloading of large freight cars are systematically expounded, and the principle and technology of monitoring overloading system of large freight cars are discussed. In order to determine whether the truck is overweight or not and to provide alarm behavior when the truck is overweight, the single-chip microcomputer STC89C52 is the central processor designed for this purpose. The weighing sensor WPL110 will convert the weight signal into the voltage signal, and then the A / D conversion chip TLC0838 will convert it into a digital signal again, and it will be easy to get the actual weight of the truck, and then the actual weight will be transmitted to the upper computer through the RS485 interface. The system then automatically compares the measured weight with the set weight, which makes it easy to tell if the truck is overweight, if it is overweight, and if it is overweight, it also shows its overweight weight.
