Embodiment Construction

[0043] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0044] Such as figure 1 As shown, the real-time road condition estimation system based on the Internet of Vehicles of the embodiment of the present invention is characterized in that it includes the following modules:

[0045] Vehicle data acquisition system, including vehicle network, vehicle platform and data acquisition software. The vehicle platform communicates with the vehicle network through the vehicle's own OBD-II interface to obtain vehicle-related data, including current time, vehicle ID, and current geographic location. The longitude and latitude, driving direction, vehicle speed, engi...

Abstract

The invention discloses a real-time road condition estimation system and method based on Internet of vehicles. The system comprises a vehicle data acquisition system used for obtaining vehicle correlation data, and at the same time, sending the vehicle data to a data management center of a server end cyclically according to a fixed cycle through a wireless network via a vehicle-mounted platform; the data management center used for, after receiving and storing the vehicle correlation data, determining GPS positioning point coordinates and the driving direction of a vehicle by use of a map matching algorithm, then carrying out algorithm processing to cyclically estimate a road stroke speed of a road, and then cyclically issuing the estimated road stroke speed to a road condition display system of a mobile terminal according to a fixed cycle; and the road condition display system used for displaying user registration, self positioning, real-time road condition query, historical stroke query, system parameter arrangement and online updating functions. The compatibility is good, real-time road condition information on the road can be efficiently obtained, and traffic congestion is reduced.

Description

technical field [0001] The invention relates to the technical field of the Internet of Vehicles, in particular to a real-time road condition estimation system and method based on the Internet of Vehicles. Background technique [0002] The rapid growth of car ownership has brought convenience to people in all aspects, and at the same time led to frequent urban road congestion. Road congestion has many negative effects. There are two main solutions, one is the traditional way of adding roads and controlling the increase in the number of vehicles, and the other is dredging. In the current situation, although ways such as expanding roads and controlling the increase in the number of vehicles can relieve traffic pressure, the use of land resources is limited after all, and this way cannot solve congestion from the perspective of sustainable development. In order to smooth the traffic, it is necessary to adopt advanced technology and continuously improve the existing road traffi...
