Wireless monitoring system of expressway vehicle

Abstract

The invention relates to an expressway vehicle monitoring system based on a wireless network communication technology, and the system comprises three parts, namely a vehicle-mounted terminal, a relay station and a vehicle monitoring information center. The expressway vehicle monitoring system is characterized by achieving functions of management, query and storage of information such as position, speed, track, front and back distances and the like of vehicles with the vehicle-mounted terminal of the system, wherein the vehicle traveling information can be displayed on a plurality of big screens at the vehicle monitoring information center; the system transmits traffic information to an expressway management department in a wireless digital transmission mode; and whether a corresponding vehicle violates the regulation, whether the vehicle has the tends to make other vehicles in danger and other security information are judged according to related driving safety regulations, furthermore, a driving promotion or accident alarm is transmitted in wireless digital transmission mode and broadcasted in voice by the management department to a driver of the vehicle violating the regulation. According to the invention, the vehicle speed is effectively monitored and beneficial promotion information is transmitted to a driver, so that the expressway accident rate can be reduced effectively.

Description

technical field [0001] The invention relates to a wireless monitoring system, in particular to a highway vehicle monitoring system based on wireless communication technology. Background technique [0002] The real-time monitoring of vehicle positioning, speed measurement, violation judgment and traffic accident warning that can realize the whole section of the expressway is one of the key technologies to be solved urgently to ensure the safe driving of expressway vehicles. The existing highway management system can only realize one-way information communication, that is, obtain vehicle information through fixed-point video or speed radar and other equipment, and upload it to the highway management department, while the highway management department can only use fixed-position traffic lights or The signage provides brief driving information to the driver. This non-two-way information interaction not only seriously affects the timely and effective traffic dispatching and mana...

Problems solved by technology

The patent for this invention effectively controls the speed of the vehicle and facilitates the determination and punishment of speeding violations on the expressway. The disadvantage is that only video processing technology is used to obtain necessary information at the entrance and exit, and it cannot provide the whole process of vehicle speed monitoring information, which is only for safe driving. Provides post-processing means, does not provide drivers with any beneficial driving reference information in advance, and cannot play an early warning role in traffic accidents

The RFID-based highway vehicle monitoring system has a relatively high degree of automation, but the laying cost of the optical communication network is high, maintenance is inconvenient, and it does not have the functions of full-process high-precision monitoring, system automatic threat judgment and alarm, etc., which is difficult to meet the rapid development of my country's modern traffic. The Urgent Demands of Development Trends
