The method comprises the following steps:
s1: establishing a communication relation between a first communication module and a second communication module;
in the embodiment of the specification, the ETC device is connected with the vehicle by one of the following modes: controller area network CAN bus, LIN bus or serial interface, for example communication between first communication module and the second communication module promptly, ETC equipment with the vehicle passes through CAN bus connection, when needs carry out information transmission, ETC equipment uploads the information on the CAN bus, vehicle controller is through receiving information on the CAN bus is handled, need to explain that, ETC equipment is connected on the vehicle power supply of vehicle, and after the vehicle was electrified, ETC equipment automatic start, and then prevent tearing open operation such as judgement, activation, avoided the back in the dress ETC equipment the condition that the external power supply appears not having the electricity to the use of ETC equipment has been influenced.
It should be noted that establishing the connection between the first communication module and the second communication module may be understood as establishing the connection between the ETC device and a vehicle controller of the vehicle, where the vehicle controller may be a vehicle Electronic Control Unit (ECU), a Vehicle Control Unit (VCU), or the like.
S2: after a vehicle is powered on, performing anti-disassembly relationship authentication between the vehicle and the ETC equipment;
wherein the vehicle is electrified to understand that car Power is in any gear such as ACC/ON, in this specification embodiment, still need establish before carrying out the authentication ETC equipment with the mapping relation between the vehicle, that is to say, through the only connection relation between the two, can avoid ETC equipment is dismantled or is changed, can for example pass through ETC equipment with the only identification code of vehicle carries out corresponding discernment authentication, the only identification code is the only authentication information of both, for example the only identification code of ETC equipment is the only coding information of OBU, including production information, address information etc. the only identification code of vehicle can be vehicle VIN sign indicating number.
Illustratively, store the VIN sign indicating number of vehicle in the ETC equipment, in addition can store the identification code of ETC equipment in the vehicle, after the vehicle is electrified, the ETC equipment also can be switched on, then the authentication that the ETC equipment will be prevented tearing open.
For example, when the vehicle stores the identification code of the ETC device, the second obtaining unit obtains the unique identification code of the ETC device, and the second judging unit compares whether the obtained unique identification code of the ETC device is consistent with the stored identification code of the ETC device, if so, the removal prevention of the ETC device is successful, and if not, the removal prevention of the ETC device is invalid;
when the ETC equipment stores the identification code of vehicle, first acquisition unit acquires the unique identification code of vehicle, and first judgement unit comparison obtains the unique identification code of vehicle with store whether the identification code of vehicle is unanimous, if unanimous, then show that the ETC equipment is prevented tearing open successfully, if inconsistent, then show that the ETC equipment is prevented tearing open and is became invalid.
In addition, in order to improve the reliability of the anti-dismantling authentication between the ETC device and the vehicle, the verification can be performed through encryption processing, for example, the identification code of the ETC device stored in the vehicle is an encryption code obtained by the unique identification code of the ETC device through a preset algorithm, or the identification code of the vehicle stored in the ETC device is an encryption code obtained by the unique identification code of the vehicle through a preset algorithm, so that the ETC device or the vehicle can be provided with a corresponding encryption module, the encryption module is provided with an affected encryption algorithm, and the anti-dismantling authentication can be performed:
when the vehicle stores the identification code of the ETC device, a second acquisition unit acquires the unique identification code of the ETC device, a second encryption unit acquires the identification code of the ETC device through a preset algorithm, a second judgment unit compares whether the acquired identification code of the ETC device is consistent with the stored identification code of the ETC device, if so, the ETC device is successfully prevented from being dismounted, and if not, the ETC device is inefficiently prevented from being dismounted;
when the ETC equipment stores the identification code of vehicle, first acquisition unit acquires the only identification code of vehicle, and first encryption unit obtains through preset algorithm the identification code of vehicle, first judgement unit comparison obtain the identification code of vehicle with store whether the identification code of vehicle is unanimous, if unanimous, then show that the ETC equipment prevents tearing open successfully, if inconsistent, then shows that the ETC equipment prevents tearing open inefficacy.
In this embodiment, in order to ensure continuous normal use of the ETC device, a verification period may be further set, and the determination of the tamper relationship may be performed at regular intervals.
It should be noted that the above is only one determination relationship in the embodiment of the present specification, and in some other embodiments, the following may also be used:
after the ETC equipment is installed, the OBU is installed on a front windshield of the vehicle;
acquiring position information of the OBU through a preset perception sensor, wherein the position information comprises azimuth information and shape information of the OBU on the windscreen in front, and marking the position information as flag bit information;
when the anti-disassembly relationship is judged, acquiring the position information of the OBU, comparing the position information with the flag bit information, and judging whether the error between the position information and the flag bit information exceeds a preset value;
if the number of the anti-dismantling devices exceeds the preset number, the anti-dismantling is invalid, and if the number of the anti-dismantling devices does not exceed the preset number, the anti-dismantling is successful.
The preset value is the condition that parts are loosened due to upset in long-time work of the vehicle, and the like, so that the OBU slightly deviates from the installation position.
In this embodiment, in order to ensure continuous normal use of the ETC device, a verification period may be further set, and the determination of the tamper relationship may be performed at regular intervals.
S3: and according to the anti-dismantling relation authentication result, a reminding module reminds the vehicle personnel.
The anti-dismantling relationship authentication result is anti-dismantling success and anti-dismantling failure, wherein when the anti-dismantling is successful, the method indicates that the ETC equipment can be normally used, the contents such as normal anti-dismantling of the ETC equipment and the like can be displayed through a vehicle display screen, and the ETC equipment can also remind of the successful anti-dismantling, such as a short dripping sound; when preventing tearing open the failure, the expression the ETC equipment is in abnormal state, and accessible vehicle display screen shows that ETC equipment prevents tearing open unusually, please in time handle content such as, of course ETC equipment also can prevent tearing open the warning of failure, for example the rush drips the sound, when vehicle personnel discovery prevents tearing open the inefficacy, can ETC equipment is installed on original vehicle, or on the ETC equipment of renewal to this car, the pencil is connected, reactivates, and the ETC function can normally.
