Road and vehicle managing system and method based on radio sensor network

Abstract

The present invention relates to a road and vehicle management system based on wireless sensor network and its method. Said network system includes the following several portions: vehicle-mounted mobile node, roadbed monitoring sensor node embedded in ground base, roadside fixed sensor node, monitoring base station and server. Besides, said invention also provides the concrete function and action of above-mentioned every portion, and also provides the working principle of said system and its concrete operation method.

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...

Problems solved by technology

[0003] The main problems in my country's current traffic management system: First, the monitoring of vehicles and roads is one-way, that is, the traffic management department only monitors and collects data from running vehicles or roads alone, especially does not provide feedback information to running vehicles and the collected weather, road conditions and traffic regulations information of the road ahead; second, the degree of networking of the traffic management system is not high, basically it still adopts a semi-manual method or the cost is high, so it is not suitable for large-scale installation and application; the third is the system The networking technology is single, and usually only wireless LAN technology is used to form a bus-type structure. The emerging ad hoc network technology solutions have not been applied and reflected, and long-distance data transmission cannot be realized.
