一种GPS车辆监控系统定位数据处理算法

Processing Algorithm in Positioning Data of GPS Vehicle Monitoring System

随着我国经济的高速发展,交通运输的合理调度和安全管理成为交通运输等行业中的重要问题。在这种情况下,一套具有精确定位和远距离调度的系统将十分必要。基于GPS/GIS的车辆监控管理系统是将全球定位技术,移动通信技术和网络技术等先进技术结合在一起的高科技系统。本文首先对GPS车辆监控系统在油田企业车辆管理中的应用进行了研究,分析了油田企业在实际车辆超速管理中遇到的问题;其次,在GPS车辆监控系统的基础上结合油田车辆超速管理的特点,设计并实现了一种定位数据的处理算法,用于设置数据筛选策略对车辆超速数据进行筛选,剔除由GPS漂移,换星,瞬间超车等情况下产生的不准确数据,对不同路段的超速记录进行分析,减少GPS平台超速报警中的误差。最后对算法在实际工作中的应用进行了说明,并对其存在的问题和作者后续工作进行了简单的总结。

Along with the rapid development of our country economy,reasonable command and safe management for transportation become important problem within the profession of transportation.In this kind of case,it is very necessary for a set of system with an accurate positioning and long-distance command.The vehicle monitoring system based on GPS and GIS is a high-tech system making up of Global Positioning System(GPS),Geographic Information System(GIS),mobile communication and network technique etc.together.At first,this thesis researches the GPS vehicle monitoring system in vehicle management of oil enterprises,and analyzes the problems of practical works.And then,combining the characteristics of the oil field vehicle management based on GPS vehicle monitoring system,a processing algorithm is designed and implemented to set screening strategy of speeding vehicles on the screening data,GPS removed from the drift-Star,and instantly overtake under such circumstances the inaccurate data on the different section of the records of speeding,speeding alarm reduction GPS platform in error.Finally,it summarizes the problem which exists in the system and the further work.
