目前,在我国的公路交通中,超限运输对于公路的损害是很严重的,相对于标准载重几倍的实际负载对路面的损害不是简单的等量倍数换算关系,而是几何数级。原设计可以运行十年的公路刚运行两年就不得不大面积的维护甚至重建。同时,伴随超限运输而来的严重安全隐患也让有关执法部门头痛。因此,改变现行按照车辆类型收费的方式,按照实际承载的重量收费,多拉货多交费,超限运输加倍收费,这样不但合理,也能从市场经济的原则对安全规范运输起到一定的引导作用。
超限检测/计重收费是目前国内新兴的用于阻止超载车辆损坏公路的最有效的措施之一。
为了制定计重收费标准,需要按计重收费模式对当前路桥收费数据进行采集。本课题要完成从计重设备上采集车辆信息通过串口上传到PC机,并进行数据分类和保存的任务。该系统前端使用开发性能优良、界面友好的Visual C++,后端数据库使用简洁、易用的Accesse。Visual C++ 通过ADO技术进行Accesse数据库的访问。串行通信使用Microsoft公司提供的ActiveX控件—Microsoft Communications Control(简称MSComm)。并提供了把数据从Accesse数据库导出成Excel表格的功能,方便用户对采集到的相关数据进行分析。

At present, China's highway traffic, overloaded highways for the damage is very serious. relative to the standard load times the actual load of road damage is not simply the equivalent conversion ratio, Geometric but several levels. The original design of the operation of the 10 highway just two years to run large areas of reconstruction or maintenance. Meanwhile, alongside overloaded from the serious safety problems also allow the law enforcement departments headache. Therefore, the change in the type of vehicles in accordance with the existing charges, according to the actual carrying the weight of charges, Dora goods more elderly. overloaded double the tolls, it will not only reasonable, also from the principles of market economy on transport safety norms play a guiding role. Unlimited testing / heavy toll is currently emerging used to prevent the overloading of vehicles damaged roads are the most effective measures. To make heavy toll standards required by the heavy toll on
