Wireless sensor web based real-time collection system of road circumstance state information

Abstract

The invention relates to a road condition real-time collecting system based on wireless sensor network, wherein it comprises detecting center, collecting node, network gate, sensor node, and pure route node; the connecting node and network gate are connected via wire; the network gate and detecting center are connected via internet or special network; the sensor node, pure route node and collecting node are connected via wireless multi-jump network. the invention uses wireless multi-jump communication, to apply network dynamic change, with self-organism, self-manage, self-adaptive properties; each node has sensor function and route function, while the abundant node distribution has high reliability and low cost, etc.

Description

technical field [0001] The invention relates to an intelligent transportation system, more specifically to a real-time collection system of road environment condition information based on a wireless sensor network. Background technique [0002] The real-time collection system of road environmental status information is an important part of intelligent road management and the basis of intelligent transportation system. The environmental status information of the road includes: roadbed, bridge, tunnel status on the road, water accumulation on the road, possible landslides or landslides in the culvert in the road or on the mountains on both sides, the impact of rain, snow, fog and other weather on the road and traffic conditions etc. The real-time collection of these road environmental status information to the monitoring center becomes the basis of traffic management, which has great practical significance for the smooth flow of roads and the safety of vehicles driving on the...

Problems solved by technology

However, in the face of an increasingly extensive and dense road network, if the traditional wired transmission information collection system is used, it is difficult to implement and promote it on a large scale due to its high network construction cost, difficult maintenance, and low flexibility.

[0003] In recent years, it has been proposed to use the cellular network of mobile phones to establish a real-time collection system for road environment information. This system must rent the operator's network during operation, which makes the operation cost very high and has little actual use value.
