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（下位机）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。系统主要由上位机和下位机组成。其中下位机由软件模拟，随机的产生车辆信息并发送到上位机。上位机将数据采集到后完成数据的分类和保存。该系统前端使用Visual C++，后端数据库使用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。该系统为公路超限运输车辆的检测提供了科学依据，具有很好的实用价值。

At present, China's highway traffic, overloaded highways for the damage is very serious. 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, this is not only reasonable, also from the principles of market economy on safety regulation of transport has played a guiding role. Unlimited testing / heavy toll is currently emerging used to prevent overloading of vehicles damaged roads are the most effective measures. In order to develop heavy toll standards required by the heavy toll on the current mode of road and bridge toll data collection. To accomplish this task from heavy equipment (crew) Acquisition of vehicles upload information through the serial port to PC, and classification of data and preservation of the mandate. The main upper and lower plane. Which crew under simula
