Embodiment Construction

[0031] The subgrade monitoring nodes in this network system are arranged around fixed nodes. The wireless communication unit of the node system adopts a wireless transceiver chip compatible with 2.4GHz IEEE 802.15.4, which has low power consumption, simple peripheral circuits, and a communication distance of up to 50 meters. The microcontroller of the node adopts ordinary 8051 single-chip microcomputer, which is cheap and easy to use. The node is powered by batteries, and the working cycle can be set to complete a complete operation every half hour or an hour according to actual needs. The node wakes up from sleep, collects roadbed data, listens to the channel, sends data, confirms that the data is sent successfully, and sleeps again , the whole process is a complete operation, and the service life of the node system can reach more than 10 years.

[0032]The vehicle-mounted mobile node is attached to the vehicle's electronic system bus, and can share data and control each othe...

Description

technical field [0001] The invention relates to the field of wireless network application technology, in particular to a road and vehicle management system and method based on a wireless sensor network. Background technique [0002] Traffic congestion and traffic safety are important factors restricting the current social and economic development, seriously affecting people's normal life. If you want to eliminate the factors that cause traffic congestion and unsafety, and provide timely road condition information for both drivers and traffic management departments, you can avoid some traffic accidents and traffic congestion, so that they can adjust and dispatch driving routes in time according to actual conditions. . Expressways are famous for their high speed, convenience, high traffic flow and safety. However, in my country, according to relevant statistics, the accident rate and death rate on expressways are higher than those on ordinary highways. The accidents caused by...
