A vehicle-mounted information monitoring device suitable for highways and its warning method

Abstract

The invention discloses a vehicle-mounted information monitoring device suitable for highways, comprising: a speed measurement module, a radio frequency communication module, a processing module, and a prompt module; the speed measurement module is used to collect the real-time speed of vehicles; The wireless signal sent by the expressway is received; the processing module is connected with the speed measurement module and the radio frequency communication module, and is used to process the received wireless signal and the collected real-time speed of the vehicle, and generate a processing result; The prompt module is connected with the processing module and is used to generate prompt information according to the processing result. The present invention can monitor and collect vehicle driving information in real time, including vehicle speed, lane information, etc., so as to realize the monitoring of the whole process of the vehicle and remind in time.

Description

technical field [0001] The invention relates to the technical field of traffic management, in particular to a vehicle-mounted information monitoring device suitable for expressways. Background technique [0002] With the continuous development of expressway construction in my country and the continuous deepening of road market reform, the coverage of transportation infrastructure construction projects, especially expressway projects, is becoming wider and wider. At the same time, the phenomenon of speeding, low-speed driving, and frequent lane changes on urban roads and expressways is very common. Therefore, traffic accidents occur frequently, and the annual direct economic loss is nearly tens of millions of yuan. posed a serious threat. Therefore, improving traffic order, reducing speeding behavior, and ensuring traffic safety are top priorities. [0003] At present, most of the expressways in my country adopt the monitoring vehicle technology based on radar or image proc...

AI Technical Summary

Problems solved by technology

Although interval speed measurement effectively avoids the shortcomings of fixed-point speed measurement and easy evasion, it still has its limitations in judging speeding by calculating the average speed: speeding personnel can extend the passing time by staying in the service area for a long time and reduce the average speed to avoid punishment ; Judgment accuracy depends on the number of fixed-point speed measurement devices, but the cost of speed measurement devices is high, and large-scale popularization requires high investment to realize full-range speed measurement, which is not conducive to implementation

Although it can detect whether the vehicle is driving at a low speed, it still uses the traditional speedometer, video screen module, and camera module, which still cannot effectively solve the problems existing in highway driving and cannot guarantee driving safety.
