Problems solved by technology

Although this method can accurately measure the driving path of vehicles in the road network, since at least one physical base station needs to be installed in each road section of the road network, the initial investment and maintenance cost of the solution are relatively high. Huge and complex, increasing the difficulty of system operation

Embodiment 1

[0035] refer to figure 1 As shown, the embodiment of the present invention discloses a method for obtaining a driving route of a motor vehicle, comprising the following steps:

[0036] S101. Set up a virtual base station based on preset rules in a road section on the road network, and set up a physical base station on all other road sections connected to the road section where the virtual base station is located; S102. Set a road section code for each road section in the road network; road section code Code the base station on each road section, including virtual base station code and physical base station code;

[0037] S103. Based on the driving path of the motor vehicle, first obtain the first coding sequence containing the physical base station code of the driving section, and obtain the second coding sequence containing the virtual base station code based on the first sequence coding;

[0038] S104. Acquire a coded sequence of a road segment based on the second coded seq...

Embodiment 2

[0059] Based on the method in embodiment 1, embodiment 2 of the present invention further explains and illustrates, as figure 2 As shown in the schematic diagram of the motor vehicle driving path, it can be seen that the road network is composed of horizontal and vertical road sections, and all road sections are set with road section codes as identification codes based on the order from bottom to top and from left to right. In Embodiment 2 of the present invention , the codes of the road sections are alphabetic, so the road network is allocated to 20 road sections whose first codes are A~S; among them, it can be seen that the longitudinal road sections in the road network are D, E, I, J, N, O, S, T, other numbers indicate transverse road segments.

[0060] Next, set virtual base stations and physical base stations on all road sections. The setting rule of the virtual base station is to select a part of the horizontal road section, and the horizontal road section has an inters...

Embodiment 3

[0064] Based on the method in the aforementioned embodiment 1, the embodiment of the present invention discloses a system for obtaining a motor vehicle travel route, including a server, a virtual base station, a physical base station, and a processing terminal;

[0065] The server is used to set a virtual base station based on preset rules in a section of the road network, and set up a physical base station on all other sections connected to the section where the virtual base station is located; set a section code for each section in the road network; section code Code the base station on each road section, including the virtual base station code and the physical base station code; first obtain the first code sequence containing the physical base station code of the driving section based on the driving path of the motor vehicle, and obtain the code sequence containing the virtual base station based on the first sequence code Encoded second code sequence; finally send the second...

Abstract

The invention discloses a motor vehicle driving path obtaining method, which is applied to the technical field of driving path detection, and comprises the following steps of setting a virtual base station in road sections on a road network based on a preset rule, and setting entity base stations on all other road sections connected with the road section where the virtual base station is located; setting a road section code for each road section in the road network, wherein the road section codes are base station codes on each road section and comprise virtual base station codes and entity base station codes; acquiring a first coding sequence containing an entity base station code on a driving road section based on a driving path of a motor vehicle, and obtaining a second coding sequence containing a virtual base station code based on the first sequence code; and obtaining a road section coding sequence based on the second coding sequence to obtain a driving path of the motor vehicle. The invention also discloses a system for acquiring the driving path of the motor vehicle. The method has the advantages that the number of base stations can be remarkably reduced while the running track of the motor vehicle can be accurately obtained, and therefore the cost needed by path detection is reduced.

Description

technical field [0001] The invention relates to the technical field of driving path detection, in particular to a method and system for acquiring a driving path of a motor vehicle. Background technique [0002] With the rapid increase of the number of motor vehicles in our country, the pace of road construction has been unable to meet the rapid development of traffic demand. Therefore, with the traffic demand as the guide, and the real-time collection, analysis and processing of dynamic traffic information as the starting point, the traffic should be carried out reasonably. Planning, management and guidance to improve the scientificity, pertinence and effectiveness of urban traffic management will become the development trend of future traffic management. Intelligent transportation based on Internet of Things technologies such as RFID technology, high-definition video recognition technology, data fusion technology, and cloud computing technology requires the collection of th...
