ERP环境下汽车衡GPRS计量监控系统的开发

摘要

In view of rigged problem of using remote control signal existed in current truck scale measurement mode, the paper proposed a design scheme of GPRS measurement and monitoring system of truck scale under ERP environment, and introduced design of hardware, software of the system and its function in details. The system adopts stepwise count and worksheet filtering method to process data, can automatically detect vehicle information without infrared positioning system, and can accurately send measurement data to supervision department of enterprise, so as to make the system break through limitation of use place, suit for field of truck scale which is unsuited to install infrared positioning system; the system uses wireless recognition technology to real-timely judge rigged data, and send these data information and alarm signal to enterprise supervision department through GPRS networks and make alarming. The practical application showed that the system is simple, practical and convenient in operation, which effectively prevents man-made cheating combining with enterprise ERP system, and improves working efficiency.%针对现有的汽车衡计量方式存在利用遥控信号作弊的问题,提出了一种ERP环境下的汽车衡GPRS计量监控系统的设计方案,详细介绍了该系统的硬件、软件设计及功能.该系统采用分段计算、列表筛选的方法进行数据处理,在没有红外定位系统时仍可以自动检测车辆信息,并可将准确的计量数据发给企业监管部门,使系统突破了使用场所的限制,可以很方便地适应一些不适合安装红外定位系统的汽车衡现场；利用无线识别技术实时判断出作弊吨位数据,并把这些数据信息和报警信号通过GPRS网络传送给企业监管部门并进行报警.实际应用表明,该系统操作简单、实用、方便,与企业ERP系统相结合有效地预防了人为作弊,提高了工作效率.
