Background technique

With the rapid expansion of domestic car ownership, my country is rapidly entering the car society, and the social problems and contradictions related to cars are becoming more and more prominent. The contradictions between cars and roads, cars and pedestrians, cars and the environment, cars and energy are becoming more and more serious. protrude. According to statistics, as of the end of 2017, the number of motor vehicles in China exceeded 310 million, and the mileage of expressways opened to traffic exceeded 131,000 kilometers, ranking first in the world. There are more than 700 toll stations on the main lines of expressways. This means that every one and a half hours of driving will pass through a main toll booth, and a large number of cars will be backlogged at the toll booth due to the long waiting time for charging, causing congestion. Especially during holidays, the roads near the toll booths will all become "parking lots" in seconds without exception. In May 2018, the executive meeting of the State Council decided to promote the cancellation of provincial toll stations on expressways, and support the use of new information technologies such as ETC and Beidou positioning technology to replace manual toll collection, so as to solve the problems that are prone to occur at provincial toll stations. Traffic jams, thereby reducing logistics costs and further improving vehicle traffic efficiency.

The electronic toll collection system (Electronic Toll Collection, referred to as ETC), by installing the vehicle electronic label (On board Unit, referred to as OBU) on the windshield of the vehicle, the Road Side Unit (Road Side Unit) erected on the roadside of the ETC lane of the toll station , referred to as RSU), using microwave dedicated short-range communications (Dedicated Short Range Communications, referred to as DSRC) technology, combined with computer networking technology and banks for background settlement processing, so as to achieve the purpose of vehicles passing through road and bridge toll stations without stopping and paying road and bridge tolls.

The existing ETC system is applied to expressway toll collection without parking. Although the traffic efficiency is improved compared with traditional manual passages, there are still some problems. For example, it is difficult to implement the unified network operation of national expressways. As a result, there are incompatibility problems in the operation management model, charging standards, and even communication interfaces between systems. Especially after the cancellation of inter-provincial toll stations, how to accurately split the charges for different road sections, how to effectively prevent path ambiguity, etc. There will be practical operational difficulties in all aspects; at present, the coverage rate of ETC lane construction is less than 30%, and the congestion of expressway toll stations is still serious, especially at inter-provincial toll stations. Statistical analysis, guide the diversion of vehicles on congested road sections, and forecast congested road conditions in advance; currently, the number of ETC users has exceeded 50 million, how to conduct traffic supervision on expressway vehicles, how to conduct network monitoring and dispatch command for key operating vehicles, etc. Traffic management services are urgent problems to be solved in future intelligent transportation systems.

Contents of the invention

The present invention overcomes the above-mentioned shortcomings of the prior art, and provides a high-speed ETC non-stop charging method and system based on Beidou high-precision positioning, which is used to realize the networked operation of a national expressway and realize non-stop charging when vehicles pass through toll stations , provide accurate billing according to the actual mileage and accurate split settlement of different road sections, solve the problem of path ambiguity, and provide technical means for the expressway management department to accurately monitor and dispatch vehicles to improve the efficiency of toll station vehicles and traffic management levels.

The technical scheme that the present invention solves the above problems is:

The invention provides a high-speed ETC non-stop charging method based on Beidou high-precision positioning, including:

Step 1. The car owner user installs the new vehicle-mounted OBU terminal integrated with the Beidou high-precision positioning chip and mobile communication chip, registers and opens the ETC service, binds the car owner information and vehicle information, and opens the bank card or electronic wallet automatic withholding agreement, and at the same time All binding information is written into the user database.

Step 2. Identify the vehicles entering the toll gate of the expressway.

When the vehicle passes through the ETC dedicated lane and is about to enter the toll entrance of the expressway and enters the vehicle identification area of the ETC lane, the roadside RSU unit performs DSRC short-range communication with the vehicle-mounted OBU terminal through the suspended microwave antenna to read the owner information bound to the OBU terminal And vehicle information, and forwarded to the network charging system for data processing.

After receiving the on-board OBU information forwarded by the roadside RSU unit, the networked toll collection system queries the user database, retrieves the owner information and vehicle information in the database, compares them, and completes the vehicle identity verification. If the vehicle information does not match, it is very likely that there is a fraudulent Passage will be refused for violations such as license plates. If the vehicle information verification is passed, the networked toll collection system will notify the car owner to start billing through SMS or APP application, and remind the car owner to confirm that the Beidou positioning function of the vehicle OBU terminal is turned on. When it is verified that the vehicle meets the passage conditions of the ETC dedicated lane, the networked toll collection system triggers the liquid crystal display unit/signal indication unit to prompt for permission to pass and the gate switch unit to open the railing and release related actions.

Step 3. Use the Beidou high-precision positioning management platform and the vehicle-mounted OBU terminal to obtain the location information of vehicles on the way to the expressway for real-time monitoring.

During highway driving, the vehicle-mounted OBU terminal will report the high-precision location information to the Beidou high-precision positioning management platform in real time through the mobile communication chip according to the positioning frequency preset by the system.

The Beidou high-precision positioning management platform can display the location of the tracking vehicle in real time on the GIS platform through the acquired vehicle location information, and can query the historical running track of the vehicle. When the vehicle enters the toll entrance of the expressway, the platform automatically marks the starting point of the expressway, and when the vehicle exits the toll exit of the expressway, the platform automatically marks the end point of the expressway, which is used in the toll station network toll system to charge according to the actual driving route. If the Beidou high-precision positioning chip has a differential signal input, the Beidou high-precision positioning management platform can clearly monitor the lane where the vehicle is located, and can accurately identify and record whether the vehicle occupies the emergency lane, whether it is illegally parked or crossed the line, and other behaviors. At the same time, expressway management departments can use the Beidou high-precision positioning management platform to provide traffic management services such as precise monitoring of passing vehicles, traffic flow analysis, congestion warning, and congestion management. The traffic management department can use the Beidou high-precision positioning management platform to realize traffic management services such as real-time monitoring, dispatching and commanding of key operating vehicles such as the transportation of hazardous chemicals passing on the expressway.

Step 4. Verify the vehicle entering the toll exit of the expressway, and perform toll settlement in combination with the complete driving route information of the entire expressway obtained in steps 2 and 3.

When the vehicle passes through the ETC dedicated lane and is about to enter the expressway toll exit and enters the vehicle identification area of the ETC lane, the roadside RSU unit performs DSRC short-range communication with the vehicle-mounted OBU terminal through the suspended microwave antenna to read the owner information bound to the OBU terminal And vehicle information, and forwarded to the network charging system for data processing.

After receiving the on-board OBU information forwarded by the roadside RSU unit, the networked toll collection system queries the user database, retrieves the owner information and vehicle information in the database, compares them, and completes the vehicle identity verification. If the vehicle information does not match, it is very likely that there is a fraudulent Passage will be refused for violations such as license plates. If the vehicle information verification is passed, the networked toll collection system will interact with the Beidou high-precision positioning management platform to obtain the complete driving path information of the entire expressway of the vehicle, and perform toll settlement according to the core algorithm of path calculation, and communicate with the roadside RSU unit The data interaction of the on-board OBU unit completes the automatic deduction of the IC card. At the same time, the network toll collection system accurately splits the collected expressway tolls according to the mileage of different road sections and allocates them to the charging units of each road section in the background.

After the networked toll collection system completes the deduction, it will trigger the liquid crystal display unit/signal indication unit to prompt related actions such as allowing passage and opening the railing of the gate switch unit to complete the entire non-stop toll collection process.

Settlement, and through the data interaction between the roadside RSU unit and the vehicle-mounted OBU unit, the automatic deduction of the IC card is completed; at the same time, the networked toll collection system accurately splits the collected expressway tolls according to the mileage of different road sections and transfers them to the background Toll units for each road section; After the networked toll collection system completes the deduction, it will trigger the liquid crystal display unit/signal indication unit to prompt related actions such as allowing passage and opening the railing of the gate switch unit to complete the entire non-stop toll collection process. 2. the high-speed ETC non-stop toll collection method based on Beidou high-precision positioning as claimed in claim 1, is characterized in that: the car owner information described in step 1 includes information such as driver's license, driving license, identity documents; vehicle information includes license plate number , model, color, annual inspection and other information. 3. implement the system of the high-speed ETC non-stop charging method based on Beidou high-precision positioning of claim 1, comprising: On-vehicle OBU terminal, used for DSRC short-range communication with roadside RSU unit to complete vehicle identity verification and IC card deduction; Among them, the vehicle-mounted OBU terminal integrates a Beidou high-precision positioning chip and a positioning antenna on the basis of traditional terminal hardware. The positioning antenna is used to receive satellite signals broadcast by Beidou navigation satellites. The Beidou high-precision positioning chip uses the satellite signals to analyze and extract useful information. The original observation data of the satellite, and the position information of the vehicle terminal is calculated by the Beidou high-precision positioning algorithm; The vehicle-mounted OBU terminal integrates a mobile communication chip, which is used to report the location information of the vehicle-mounted terminal to the Beidou high-precision positioning management platform in real time, and to receive external differential signal input; the mobile communication chip can choose GPRS/CDMA/TD- Any one of SCDMA/WCDMA/CDMA2000/4G; The Beidou high-precision positioning chip supports external differential signal input, and receives RTD/RTK differential signals from CORS reference stations or high-precision location service cloud platforms to improve its own positioning accuracy. RTD differential positioning services can meet sub-meter level/ Lane-level positioning and monitoring requirements, RTK differential positioning services can achieve centimeter-level high-precision positioning accuracy; According to the location information reported by the vehicle-mounted OBU terminal, the Beidou high-precision positioning management platform displays the location of the tracking vehicle in real time on the GIS platform, and queries the historical running track of the vehicle; when the vehicle enters the toll entrance of the expressway, the platform automatically marks the starting point of the expressway. When the vehicle drives out of the toll exit of the expressway, the platform automatically marks the end point of the expressway, which is used for the networked toll collection system of the toll station to charge according to the actual driving route; if the Beidou high-precision positioning chip has differential signal input, the Beidou high-precision positioning management platform can clearly monitor it. The lane where the vehicle is located accurately judges and records whether the vehicle occupies the emergency lane, whether it is illegally parked or crossed the line; at the same time, through the unified network monitoring of the vehicles installed with the vehicle-mounted OBU terminal, it assists the expressway management department to monitor the passing vehicles. Provide technical platforms for applications such as precise monitoring, traffic flow analysis, congestion warning, and congestion management, and assist traffic management departments to realize traffic management services such as real-time monitoring, dispatching and commanding of key operating vehicles such as hazardous chemical transportation on expressways; The roadside RSU unit performs DSRC short-range communication with the vehicle-mounted OBU terminal through the suspended microwave antenna. The charging information sent by the vehicle interacts with the IC card of the vehicle-mounted OBU unit to complete automatic deduction; After receiving the on-board OBU information forwarded by the roadside RSU unit, the networked toll collection system queries the user database, retrieves the owner information and vehicle information in the database, compares them, and completes the vehicle identity verification. If the vehicle information does not match, it is very likely that there is a fraudulent If the vehicle information verification passes, the networked toll collection system will interact with the Beidou high-precision positioning management platform to obtain the complete driving path information of the entire expressway of the vehicle, and calculate the toll according to the core algorithm of path calculation. Settlement, and through data interaction between the roadside RSU unit and the vehicle-mounted OBU unit, the deduction of the IC card is completed; at the same time, the networked toll collection system accurately splits the collected expressway tolls according to the mileage of different road sections and allocates them in the background to each Road toll unit; after the network toll system completes the deduction, it will trigger the liquid crystal display unit/signal indication unit to prompt the passage to be allowed and the gate switch unit to open the railing and release related actions; The communication connection between the networked toll collection system and the roadside RSU unit.
