GPS物流车辆行驶数据采集与存储系统的开发

摘要

为了便于物流企业实时采集受控车辆的行驶数据,以便精确掌握车辆的行驶过程,设计开发了一种基于GPS的物流车辆行驶数据采集与存储系统.该系统包括车载移动终端、数据传输网络和监控中心.首先,该系统利用多线程技术采集对装有车载设备的受控车辆的行驶数据.然后,通过数据截取获取受控车辆的经度、纬度、速率以及时间信息.最后,利用CDMA无线通信技术远程传输到监控中心并存储到后台数据库中,为管理人员查阅分析车辆当前状态提供依据.通过测试,证明该系统可以提高物流企业车辆的运营效率和安全行驶率,有效地杜绝车辆超速行驶、跑私车以及乱停乱放等现象,有着较好的经济效益.%In order to facilitate logistics enterprise to acquire motion data of controlled vehicles and accurately master vehicles driving process,a logistics vehicle based on GPS data acquisition and storage system is designed.The system consists of vehicle mobile terminal,data transmission network and monitoring center.First,the system makes use of multi-threading technology to obtain traffic data of equipped with controlled vehicles on-board equipment.Then through the data capture process it can acquire longitude,latitude,speed and time of the controlled vehicles.Finally,by using CDMA wireless communication technology the data is remotely transmitted to the monitoring center and stored in the database.It provides basis for managers to analyze the current state of the controlled vehicles.Through test,it proves that the system can improve the operation efficiency and safety of logistics enterprises vehicle.What's more,it effectively eliminates the phenomena of overtaking,privately driving for other purpose and disorderly parking place.In a word,it has a good economic benefit.
