[0030] See Figure 1 As shown, an embodiment of the present utility model discloses a toll evasion audit system based on the integrated application of Beidou positioning and ETC technology, including:

[0031] On-vehicle device, combined with Figure 2As shown in the figure, the in-vehicle device includes an ETC function module 12, a Beidou positioning module 11, a vehicle status detection module, and a mobile communication function module 13. The vehicle status detection module is used to obtain vehicle status information. Specifically, the vehicle status detection module is connected to a six-axis sensor 16 on the vehicle through a CAN bus interface 15 to obtain the driving status information of the vehicle;

[0032] A toll collection platform, which is communicatively connected to the in-vehicle device. The toll collection platform can receive the vehicle status information and / or positioning information uploaded by the in-vehicle device through the mobile communication function module, and determine the toll collection information according to the positioning information;

[0033] Specifically, the in-vehicle device is connected to a six-axis sensor through a vehicle CAN bus interface to obtain vehicle status information; the in-vehicle device uploads the vehicle status information and positioning data to the toll collection background through the mobile communication function module; the in-vehicle device fails to upload the vehicle positioning data to the toll collection platform for more than five minutes; the toll collection platform determines the vehicle as a suspected toll evasion vehicle and sends the vehicle-related information to the audit background;

[0034] An audit background, which is communicatively connected to the toll collection platform. The audit background can receive the positioning failure vehicle information uploaded by the toll collection platform and analyze and determine the list of vehicles to be audited.

[0035] Specifically, the audit background analyzes the relevant information and data of the vehicle and forms a status list of the vehicle.

[0036] Then, the vehicle makes up the toll according to the audit result; after the vehicle completes the toll payment, the audit background updates the vehicle status list and then prints a toll payment receipt as needed.

[0037] In summary, the audit system provided in this embodiment solves the problems such as the incorrect collection of highway tolls caused by human factors, equipment failures, etc., and improves the accuracy and timeliness of highway audits.

[0038] In some embodiments, the in-vehicle device further includes an interference signal detection module, and the interference signal detection module is at least one of a signal power detection module, a correlation peak detection module, or an antenna array detection module.

[0039] In some embodiments, the in-vehicle device further includes an anti-disassembly module 14, and the anti-disassembly module 14 is a mechanical anti-disassembly module or a light-sensing anti-disassembly module.

[0040] In some embodiments, the mechanical anti-disassembly module includes an anti-disassembly mechanical rod. The anti-disassembly mechanical rod is in a compressed state under normal conditions. When the vehicle-mounted device is disassembled, the anti-disassembly mechanical rod pops up, and the vehicle-mounted device is placed in a failure state after receiving the pop-up signal.

[0041] In some embodiments, the light-sensing anti-disassembly module includes a light sensor and an alarm. When the vehicle-mounted device is disassembled, the light sensor senses the external infrared rays. After the alarm receives the induction signal from the light sensor, it emits an alarm signal, and the vehicle-mounted device is placed in a failure state after receiving the alarm signal.

[0042] The anti-disassembly function of the vehicle-mounted device has one-time effectiveness when the device is installed and used. When the vehicle-mounted device is disassembled, it will fail and cannot upload data. The anti-disassembly function of the vehicle-mounted device is divided into mechanical anti-disassembly and light-sensing anti-disassembly. Mechanical anti-disassembly means that the vehicle-mounted device contains an anti-disassembly mechanical rod. Under normal conditions, the mechanical rod is in a compressed state. Once the device is disassembled, the mechanical rod will pop up, causing the vehicle-mounted device to fail and unable to upload data. Light-sensing anti-disassembly means that the vehicle-mounted device is equipped with a light sensor and an alarm. Once the vehicle-mounted device is disassembled, the light sensor senses the external infrared rays, the optical signal is converted into an electrical signal and an alarm is generated, and finally the vehicle-mounted device is in a failure state and cannot upload data.

[0043] In some embodiments, the fee evasion auditing system based on the integration application of Beidou positioning and ETC technology further includes a front-end auditing unit. The front-end auditing unit can detect vehicles traveling on the highway and transmit the information of the vehicles to the toll collection platform. Specifically, the front-end auditing unit completes the auditing of the vehicles according to the aforementioned status list.

[0044] In some embodiments, the front-end auditing unit includes roadside auditing points, mobile auditing points, and mobile auditing terminals.

[0045] In some embodiments, as shown in Figure 3 the roadside auditing points include gantries, ETC antennas 22, license plate recognition devices 23, identification industrial computers, and network systems 21.

[0046] It should be noted that the roadside auditing points are arranged in sections prone to ambiguous billing, sections with weak Beidou or mobile communication capabilities, and sections avoiding frequency points close to 5.8 GHz. The roadside auditing points collect vehicle license plates and ETC data and upload them to the toll collection background. When the toll collection background fails to receive the ETC data of the same vehicle more than 5 times, the toll collection background determines the vehicle as a suspected fee evasion vehicle and sends the relevant information of the vehicle to the auditing background. The auditing background analyzes the relevant information of the vehicle and forms a status list of the vehicle.

[0047] In some embodiments, referring to Figure 4 As shown, the mobile audit point is arranged on the audit vehicle 37 and includes a roof pan-tilt 33, a camera, an ETC roadside unit 32, an industrial computer 34, a communication module 35, a license plate recognition device 31, and a Beidou positioning module 36. The mobile audit point can achieve the following functions: it can adjust the driving route according to the audit background management; conduct real-time audits on passing vehicles and compare them with the vehicle status list in the audit background in real time; intercept vehicles on the status list and query and recover tolls from them under safe circumstances; update the vehicle status list in the audit background in real time according to the vehicle payment situation; and print the payment list receipt in real time.

[0048] In some embodiments, in combination with Figure 5 As shown, the mobile audit terminal 42 includes an ETC communication module, a camera, and a mobile communication module. The mobile audit terminal is an audit device for single-person use, which is easy to carry and operate; it can query and recover tolls from vehicles on the status list under safe circumstances; update the vehicle status list in the audit background in real time according to the vehicle payment situation; and can also print the payment list receipt in real time. Specific embodiments

[0050] The in-vehicle device consists of a Beidou positioning module 11, an ETC function module 12, a mobile communication module 13, an anti-disassembly module 14, and a CAN bus interface 15. The CAN bus interface 15 is connected to the six-axis sensor 16 of the vehicle component vehicle to obtain vehicle driving status information; the Beidou positioning module transmits vehicle positioning data to the toll collection platform through the mobile communication module; the toll collection platform collects highway tolls according to the positioning data information; for vehicles with toll evasion behaviors, the in-vehicle device has the function of predicting their behaviors; specifically:

[0051] The in-vehicle device is connected to the vehicle CAN bus; the in-vehicle device obtains the real-time status of the vehicle six-axis sensor through the CAN bus; the vehicle six-axis sensor includes a three-axis acceleration sensor and a gyroscope; the three-axis acceleration sensor is used to calculate the traveling direction and speed of the target vehicle. Its three axes are: the positive direction of the X axis is in the due front of the vehicle, the positive direction of the Y axis is on the left side of the vehicle, and the positive direction of the Z axis is vertically upward from the ground of the vehicle; the three-axis acceleration sensor can measure the accelerations in three directions and obtain the function of acceleration a with respect to time t in each direction; the acceleration a is the derivative of speed, that is, a = dv / dt, and then the function of speed v in each direction can be obtained:

[0052] v = g(t) = ∫a dt

[0053] The speeds in each direction can be calculated according to the formula; according to the formula:

[0054] |v| = sqrt[(v X ) 2 +(v Y ) 2 +(v Z ) 2 )

[0055] The traveling speed of the vehicle can be calculated.

[0056] The gyroscope calculates the angular position of the target vehicle, where the elevation angle rotates around the X-axis, the yaw angle rotates around the Y-axis, and the roll angle rotates around the Z-axis. The steering angular velocities in three directions are measured by the gyroscope, and the angular position in each direction can be obtained through integral calculation with respect to time t:

[0057]

[0058] According to the formula:

[0059]

[0060] The angular position of the vehicle can be calculated.

[0061] When the v or φ is not equal to 0, it indicates that the vehicle is in a driving state; when the v or φ is equal to 0 and the value remains unchanged for 15 consecutive minutes, it can be determined that the vehicle is in a stopped state.

[0062] After the vehicle is started, the on-vehicle terminal is in a normal working state, and the traveling path and data of the vehicle can be viewed through the toll collection platform; when the vehicle shields the Beidou positioning signal, the toll collection platform cannot obtain the Beidou positioning information, but the on-vehicle device obtains the v or φ of the vehicle through the CAN bus and uploads the real-time status information of the vehicle to the toll collection platform, so as to pre-judge whether the vehicle is in a stopped state at this time. When the Beidou signal is lost during the driving state of the vehicle and lasts for more than five minutes, the on-vehicle device pre-judges that the vehicle is suspected of being artificially interfered or abnormal, and the on-vehicle device uploads the vehicle information to the toll collection platform through the mobile communication module, and the toll collection platform transmits the vehicle information to the audit background, and the audit background focuses on observing the vehicle.

[0063] It should be noted that the vehicle-mounted device has the ability to detect interference signals; when the vehicle-mounted device detects an interference signal nearby, it will issue an alarm reminder; the vehicle-mounted device pre-judges that the vehicle is suspected of being artificially interfered with or abnormal; the vehicle-mounted device uploads the vehicle information to the toll platform through the mobile communication module, and the toll platform transmits the vehicle information to the audit background, and the audit background makes key observations on the vehicle; the alarm reminder can be in the form of sound or light; the interference signal detection technology of the vehicle-mounted device can be realized through signal power detection technology, correlation peak detection technology, and antenna array detection technology.

[0064] Specifically, as Figure 2 shown, the vehicle-mounted terminal consists of a Beidou positioning module 11, an ETC function module 12, a mobile communication module 13, an anti-disassembly module 14, and a CAN bus interface 15. Among them, the CAN bus interface 15 is connected to the vehicle component, the vehicle six-axis sensor 16, for obtaining vehicle driving status information.

[0065] As Figure 3 shown, the roadside audit point consists of 21 - audit network system, 22 - ETC antenna, 23 - license plate recognition device, 24 - license plate recognition and ETC antenna communication area, 25 - audit object. Among them, when the 22 - ETC antenna and 23 - license plate recognition device are in working state, their 24 - license plate recognition and ETC antenna communication area covers the entire cross-section of the driving lane and is connected to the 21 - audit network platform system through the network. When the 25 - audit object equipped with the vehicle-mounted device passes through the roadside audit point, the 22 - ETC antenna and 23 - license plate recognition device collect its license plate information and ETC vehicle information and upload it to the 21 - audit background, and the system analyzes and determines whether the 25 - audit object has the behavior of evading tolls.

[0066] As Figure 4 shown, the mobile audit point consists of 31 - license plate recognition device, 32 - ETC roadside unit, 33 - roof cloud platform, 34 - industrial control computer, 35 - communication module, 36 - Beidou positioning module, 37 - audit vehicle. Among them, when the 32 - ETC roadside unit is in working state, its 38 - ETC signal coverage range is based on covering the entire lane; when the 31 - license plate recognition device is in working state, its 39 - license plate recognition range is based on covering the entire lane. When the passing vehicle equipped with the vehicle-mounted device passes through the signal coverage range of the mobile audit point, the 31 - license plate recognition device and the 32 - ETC roadside unit collect the license plate information and ETC vehicle information of the passing vehicle. When the vehicle status list in the audit background contains the collected vehicle information, the mobile audit point conducts a security interception on the corresponding vehicle and pursues the toll.

[0067] AsFigure 5 As shown in the figure, the mobile audit terminal consists of 41 - audit object, 42 - mobile audit terminal, and 43 - audit background. The auditor holds the 42 - mobile audit terminal to collect license plate information and ETC vehicle information of the 41 - audit object equipped with the vehicle-mounted device, and uploads it to the 43 - audit background. The system analyzes and determines whether the 41 - audit object has the behavior of evading fees.

[0068] It should be noted that although the present utility model is disclosed above with preferred embodiments, it is not used to limit the present utility model. Any person skilled in the art can make possible changes and modifications without departing from the spirit and scope of the present utility model.
