摘　　要：基于物流业存在货物跟踪间断性明显、贵重物品丢失或有毒气体泄露不易判定责任等问题，该文提出选用我国自主研发的北斗定位系统构建车栽终端，打破定位系统主要依赖于国外的局面，解决物流跟踪不及时的问题。测试结果表明，物流车栽终端稳定可靠，Qt界面能够及时显示定位信息。延时误差在2～5s之间。Based on the presence of the logistics sector cargoes tracking intermittent obviously and difficult to deter- mine responsibility for the loss of valuables catgoes or dangerous chemical goods leaking and other issues,this paper presented that vehicle terminal adopts our self-developed Beidou positioning system,breaking positioning system mainly depends on the abroad,solving the problem of logistics tracking not timely. Test results show that logistics vehicle terminal is stable and reliable,Qt interface displays timely positioning information,the delay error between 2-5 s.
