中文摘要：

在南方林区,林产品为凭证运输,运输数量、时间、轨迹均要求与码单吻合。传统执法方法给现代林业生产带来了许多困扰,因此研制了一套运输监管系统,通过GPS技术获得车辆实际运输起止时间、起点、轨迹、终点,并通过GPRS技术与服务器、执法车辆的语音手机连接组成了无线物联网。服务器接收到运输轨迹数据后和检尺码单数据对比可实现电子监查,指派最近的执法车追踪检查异常的运输行为。经林区环境实测证实,该设备平均延时2.7s,丢包率为1.2%,能达到监控轨迹的要求。该设备应用后能够节省执法人力资源、降低执法开支,提高管理科学化水平。

英文摘要：

In the southern forest region of China,forest products transportation has been authorized,and the document confirmation,transport quantity,time and track need to be consistent with timber scaling checklist.The traditional supervisory measures have some negative influence on forestry production.Transportation Supervisory System was established in the project.The actual timetable of the transport,including starting point,track and finishing point was received by GPS receivers,and a wireless Internet of Things（IOT） was formed by connecting with servers and official mobile phones by GPRS.After the transport track information was received by server and compared with timber scaling checklist,the electronic supervision could be achieved,and the nearest law enforcement vehicle would be sent to track and inspect the transport abnormity.The field test of forestry showed that the average delay of this system was 2.7 s,packet loss rate 1.2%,which met the requirements of track supervision.The application of this system would save law enforcement human resource,reduce law enforcement cost and enhance scientific management.
