Embodiment Construction

[0037] Such as Figure 1-8 As shown, the real-time road condition perception system based on the vehicle-mounted Beidou positioning terminal of the present invention includes a vehicle-mounted terminal and a server end;

[0038] Among them, the vehicle-mounted terminal includes a Beidou module, a communication module, a speed measurement module, and a display module:

[0039] 1) Beidou module, which obtains the real-time latitude and longitude coordinates Loc(x, y) of the vehicle;

[0040] 2) The speed measurement module is connected with the speedometer of the vehicle itself, and directly reads the real-time speed v of the vehicle;

[0041] 3) The communication module is connected to the mobile network through GPRS to communicate with the server. The communication protocol adopts the socket protocol, and the vehicle terminal actively initiates a communication request, and collects the vehicle speed information v and real-time location information Loc(x, y) with the establish...

Abstract

The invention provides a real-time traffic status sensing system based on a vehicular Beidou positioning terminal. The real-time traffic status sensing system is characterized by comprising a vehicular terminal and a server-side, wherein the vehicular terminal comprises a Beidou module, a communication module, a speed measuring module and a display module; and the server-side comprises a data processing module, a data storage module, a traffic status analyzing module and a server communication module. A Beidou navigation system is effectively utilized and detects traffic statuses in real time, a utilized machine learning method has the advantage of short training time under the condition of high data quantity, the complete degree of a model is improved by an incremental updating method, and the accuracy of a calculated result is improved. By the real-time traffic status sensing system, real-time high-accuracy traffic detection is realized, a driver can conveniently select a travelling path well according to a detected result, time is saved, energy consumption is reduced, the pressure of a road section easy to jam is also reduced, and the service life of a road can be prolonged.

Description

technical field [0001] The invention relates to Beidou positioning and road condition analysis, and in particular to a system for estimating road congestion by real-time monitoring of road vehicles and other road condition information using an extremely fast learning machine algorithm. Background technique [0002] At present, with the continuous development of the urbanization process, the number of vehicles in the city is increasing rapidly, and road congestion has become a major trouble for people to travel. How to accurately and quickly obtain real-time road condition information for instant selection of the optimal route has also become one of the hot issues. one. Existing technologies for real-time reflection of road condition information are mostly based on real-time monitoring cameras on each road section to capture traffic flow information, and then provide real-time feedback through broadcasting or road electronic screens. This requires the installation of cameras ...
