Method and system for updating road condition information in real time based on vehicle tablet terminal

Abstract

The invention discloses a method and a system for updating road condition information in real time based on a vehicle tablet terminal. The method provided by the invention comprises the following steps that: a server at the network side obtains the information of a vehicle running on the road based on RFID (Radio Frequency Identification) readers arranged at both sides of the road, wherein an RFID tag is pasted on the vehicle; the server receives the road condition request information sent by the user vehicle based on the tablet terminal, wherein the road condition request information includes the position information of the vehicle in which the user is, and the tablet terminal identifier; and the server at the network side inquires the road condition information under the environment of the user vehicle based on the road condition request information, and transmits the inquired road condition information to the tablet terminal of the user vehicle, thus an electronic map in the tablet terminal can analyze the road condition information, generate the current road condition information and display the current road condition information for the user. The method provided by the invention can display the road condition information of the road through the tablet terminal in real time, only needs the cheap RFID without using the precise GPS (Global Positioning System) positioning, and has the advantage of wide promotion area.

Description

technical field [0001] The invention relates to the technical field of tablet computer terminals, in particular to a method and system for updating road condition information in real time based on a vehicle-mounted tablet terminal. Background technique [0002] At present, with the rise of the Internet of Things, the Internet of Vehicles has received more and more attention. Due to the portability of the tablet terminal and the intuitive simplicity of operation, the tablet terminal acts as a terminal in the Internet of Vehicles. What is the Internet of Vehicles? The Internet of Vehicles refers to the use of advanced sensing technology, network technology, computing technology, control technology, and intelligent technology to comprehensively perceive roads and traffic, and realize the interaction of large-scale and large-capacity data between multiple systems. Each car is under full traffic control, and each road is under full-time and space-time traffic control, in order t...

Problems solved by technology

[0004] The first manual solution obviously faces the disadvantages of inaccurate data, high labor cost and not real-time

The second type is difficult to count due to the large differences in the vehicle-mounted terminal equipment; and the current solutions generally require a GPS module to combine with positioning, which is relatively dependent on GPS and has the disadvantage of positioning deviation
