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.
