High-risk road traffic safety early warning and controlling system and method based on internet of things

Abstract

The invention discloses a high-risk road traffic safety early warning and controlling system and method based on the internet of things. The system comprises a weather detection system and a radar velocimeter which are arranged on the road side of a high-risk road segment; the radar wave emitted by the radar velocimeter is capable of covering the high-risk road segment; in addition, a master used for on-site controlling is connected to a PLC connected to the coil of a first relay. Thus, by means of the combination of the structure and the method, the defects that in the prior art, the systematic research of the high-risk road segment is in shortage, the capability of providing professional service is limited, a visibility meter and a road condition sensor are usually applied in a separated manner, information can be provided independently instead of being monitored and controlled integrally and uniformly due to the lack of systematic, the manner is passive, and a system which is capable of guiding and controlling in real time to guarantee traffic security by analyzing the weather factors, vehicle factors and peripheral pedestrian conditions uniformly cannot exist are avoided.

Description

technical field [0001] The invention belongs to the technical field of the Internet of Things, and specifically relates to a traffic safety early warning and control system and method for high-risk road sections based on the Internet of Things, especially to the field of intelligent transportation, intelligent traffic information services of the Internet of Things, WIFI / 3G data transmission, and server information The technical field of centralized analysis and information push. Background technique [0002] In recent years, with the application of various telemetry technologies, networks, databases, and GPS technologies, the traffic meteorological monitoring system of foreign high-risk road sections can provide more abundant, timely, effective, and comprehensive information to road maintenance, traffic operation management, and public travel, reducing road traffic. maintenance and operation costs, and improve road operation services and safety levels. However, the researc...

AI Technical Summary

Problems solved by technology

Such a structure combined with its method avoids the overall lack of systematic research on high-risk road sections in the prior art, and the ability to provide professional services is still very limited. Visibility meters and road surface state sensors are usually used in the form of separate components, which is also impossible. Systematization leads to the fact that such information can only be provided separately, unable to be centrally and uniformly monitored, the methods are all passive, and there is still a lack of real-time unified analysis of meteorological factors, vehicle factors, and surrounding pedestrian conditions to induce real-time control to ensure traffic safety.
