Embodiment 1

[0042] see figure 1 The flow chart of the method for obtaining the vehicle position through ground sense provided by the embodiment of the present invention is shown, and the method for obtaining the vehicle position includes the following steps:

[0043] Statistics of the number of vehicles:

[0044] A. When the vehicle passes through the ground, the vehicle count N increases by 1;

[0045] B. When the vehicle passes the sense of leaving the ground, the vehicle count N decreases by 1;

[0046] Land sense block division:

[0047] C. An independent sense of land in the state of having a car is a land sense block, or a plurality of adjacent land senses that are continuously in the state of having a car is a land sense block, and the number of land sense blocks is M;

[0048]Judging the location information of the ground sense:

[0049] D. If N is equal to M, the position of each ground sense block is the ground sense position information of the corresponding vehicle;

Embodiment 2

[0060] see image 3 and Figure 4 The flow chart of the non-stop charging method for intelligently separated vehicles provided by the embodiment of the present invention, the non-stop charging method includes the following steps:

[0061] Obtain the electronic tag position information of the vehicles in the lane through the antenna;

[0062] In the ETC system, the RSU (Road Side Unit) obtains the smooth phase information of the electronic tag through the electronic tag, and obtains the two-dimensional coordinate system projected on the lane through phase information calculation: [X, Y]. The construction width of the ETC lane is a standard width, usually plus or minus 1.8 meters horizontally. Therefore, in the two-dimensional coordinate system of the electronic label, the electronic label of the current track or the adjacent track can be calibrated by judging the X axis. The longitudinal coordinate positions of the electronic tags arranged sequentially in the electronic tag ...

Embodiment 3

[0078] see Figure 5 , a block diagram of a vehicle ground sense position acquisition device provided in an embodiment of the present invention, the vehicle ground sense position acquisition device is used in an electronic non-stop toll collection system, and the vehicle ground sense position acquisition device includes:

[0079] The vehicle counting module is used to count the number of vehicles in the lane. When the vehicle passes through the ground sense, the vehicle count N increases by 1; when the vehicle passes through the ground sense, the vehicle count N decreases by 1;

[0080]The ground sense block division module is used to receive the ground sense state sent by the ground sense, and divide the ground sense in the state of vehicle in the lane into ground sense blocks. The sense is a ground sense block, or a plurality of adjacent ground sense blocks that are continuously in the state of having a car is a ground sense block, and the number of ground sense blocks is M;...

Abstract

The invention discloses a method for acquiring the locations of vehicles, a device, a non-stop electronic toll collection method and a non-stop electronic toll collection system and belongs to the intelligent transportation field. The method for acquiring the locations of the vehicles comprises the following steps that: A, when a vehicle passes by an entering ground sensor, vehicle counts N are increased by 1; B, when the vehicle passes through a departure ground sensor, the vehicle counts N are decreased by 1; C, ground sensing block division is performed: one independent ground sensor having a vehicle existing state is adopted as one ground sensing block, or a plurality of adjacent ground sensors of which the states are continuous vehicle existing states are adopted as one ground sensing block, and the number of the ground sensing blocks is M; and D, ground sensing location information judgment is performed: when N is equal to M, the location of each ground sensing block is the ground sensing location information of a corresponding vehicle, wherein M and N are both integrals larger than or equal to 1. According to the method for acquiring the locations of the vehicles of the invention, one independent ground sensor having a vehicle existing state or a plurality of adjacent ground sensors of which the states are continuous vehicle existing states are adopted as one ground sensing block; and the locations of the vehicles in a lane can be obtained through the number of the vehicles and the number of the ground sensing blocks, and therefore, the location information of the vehicles can be obtained accurately.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a method and a device for obtaining a vehicle position and a method and a system for non-stop charging. Background technique [0002] Electronic Toll Collection (ETC, Electronic Toll Collection) has been widely promoted in China. In the traditional ETC lane layout, although there is a sense of ground in the lane, after many vehicles enter the ETC lane, if the included models are relatively For large vehicles, the existing ground sensing system cannot tell how many vehicles there are, and thus cannot accurately obtain the location information of the vehicles. In addition, because the traditional ETC lane layout cannot accurately obtain the position information of all vehicles in the lane, it cannot really solve the common car-following interference and adjacent lane interference in the current ETC lane. Afterwards, cross-trading of OBU vehicles led to wrong deductions, a...
