摘要
为对物流车辆进行精准定位、检测和实时跟踪,需要物流车辆智能监控系统设计;当前使用的监控系统,在物流车辆进行运输的过程中,有遮挡物出现时无法精准的对物流车辆进行定位,当物流车辆停放在室内停车场时可能出现定位不到物流车辆的情况;为此,提出一种基于GPS的物流车辆智能监控系统设计方案;该系统硬件部分包括:GPS车载终端、监控中心服务器群和控制终端三部分,同时将全球定位系统与地理道路信息相结合,利用联通网络与国际互联网传输相关信息;系统软件部分使用联通分组通信技术,通过GIS软件与管理信息系统进行无缝连接,并由单片机S3C2440A向GPS模块发送控制中心下达指令,GPS接收指令并给予反馈,通过有效的分析反馈结果来提高监控终端的运行速度、稳定性以及精准度;GPS定位功能采用TDOA算法对物流车辆进行定位;实验证明,所提系统可以对物流车辆精准定位、实时监测和有效跟踪。
In order to accurately locate, detect and track the logistics vehicle, the intelligent monitoring system of logistics vehicle is de- signed. The current monitoring system used in the process of transportation, logistics vehicles, there are obstructions appear unable to accu- rate positioning of the vehicle, when the logistics vehicles parked in the parking lot when the indoor positioning is not possible to logistics ve- hicles. Therefore, this paper proposes a design scheme of intelligent monitoring system based on GPS. The hardware of the system includes： a GPS vehicle terminal and the monitoring center server group and control terminal, while the global positioning system and geographic infor- mation combined with road, Unicorn Network and Internet information transmission- system software uses Unicorn packet communication technology, seamless connection through GIS software and management information system, and S3C2440A MCU GPS module to send to the control center issued a directive, GPS receive instructions and give feedback through effective feedback analysis results to improve the running speed, terminal stability and accuracy; using GPS positioning function of logistics vehicle positioning algorithm TDOA. The experimental re- sults show that the proposed system can be used for precise positioning, real-time monitoring and effective tracking.
