Abstract
The invention provides a vehicle-mounted terminal anti-disassembly detection method based on data statistics detection, which comprises the following steps of through the data acquisition function of an OBD vehicle-mounted terminal: s1: detecting whether a built-in battery supplies power; s2: if the built-in battery does not supply power, the controller is not normally connected and is not detached; s3: if the built-in battery supplies power, performing removal detection; s4: if the built-in battery supplies power, whether external power supply exists needs to be detected. If the external power supply exists, the controller is not detached; s5: when only the built-in battery supplies power, the drift information of the GPS is detected. If the controller terminal moves under the condition of no external power supply, the controller terminal is judged to be in the dismantling action; the invention has the beneficial effects that: high efficiency and effectiveness, and the detection mode is hidden and is not easy to be cracked by people.
Description
Technical Field
The invention belongs to the technical field of automotive electronics, and particularly relates to a vehicle-mounted terminal anti-disassembly detection method based on data statistics detection.
Background
With the promotion and upgrade of emission regulations, the national regulatory authorities gradually increase the anti-dismantling detection requirements for the on-board terminals of the emission regulatory devices (OBD). In the conventional detection mode, corresponding detection is generally carried out through communication with other controllers. The commonality is poor, and the suppliers of different controllers are required to cooperate, and colleagues modify the two-part software design.
Disclosure of Invention
The invention provides a vehicle-mounted terminal anti-disassembly detection method based on data statistical detection, which carries out data statistical analysis on an algorithm through the data acquisition function of an OBD vehicle-mounted terminal; when the GPS signal is found to drift and change and the data information of the CAN bus is abnormal, the state that the vehicle-mounted terminal is detached CAN be analyzed.
The invention provides a vehicle-mounted terminal anti-disassembly detection method based on data statistics detection,
s1: detecting whether a built-in battery supplies power;
s2: if the built-in battery does not supply power, the controller is not normally connected and is not detached;
s3: if the built-in battery supplies power, performing removal detection;
s4: if the built-in battery supplies power, whether external power supply exists needs to be detected. If the external power supply exists, the controller is not detached;
s5: when only the built-in battery supplies power, the drift information of the GPS is detected. If the controller terminal moves under the condition of no external power supply, the controller terminal is judged to be in the dismantling action.
The invention has the beneficial effects that: high efficiency and effectiveness, and the detection mode is hidden and is not easy to be cracked by people. Meanwhile, other controllers are not needed to be matched, and any hardware module is not needed to be added. Has great advantages in accuracy and economy.
Detailed Description
The present invention is described in detail below, and the description in this section is merely exemplary and explanatory and should not be construed as limiting the scope of the present invention in any way.
The invention carries out statistical analysis on data in an algorithm through the data acquisition function of the OBD vehicle-mounted terminal. The functions are activated after the whole vehicle is matched with the installation terminal, and then continuous monitoring analysis is carried out in operation, and temporary monitoring analysis is carried out in the awakening process. When the GPS signal is found to drift and change and the data information of the CAN bus is abnormal, the state that the vehicle-mounted terminal is detached CAN be analyzed.
The invention provides a vehicle-mounted terminal anti-disassembly detection method based on data statistics detection,
s1: detecting whether a built-in battery supplies power;
s2: if the built-in battery does not supply power, the controller is not normally connected and is not detached;
s3: if the built-in battery supplies power, performing removal detection;
s4: if the built-in battery supplies power, whether external power supply exists needs to be detected. If the external power supply exists, the controller is not detached;
s5: when only the built-in battery supplies power, the drift information of the GPS is detected. If the controller terminal moves under the condition of no external power supply, the controller terminal is judged to be in the dismantling action.
It is noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," and the like are used in an orientation or positional relationship indicated based on the orientation or positional relationship shown for ease of description and simplicity of description, and do not indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
The above-described embodiments of the present invention do not limit the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the scope of the claims of the present invention.
Claims (1)
1. A vehicle-mounted terminal anti-disassembly detection method based on data statistics detection comprises the following steps:
s1: detecting whether a built-in battery supplies power;
s2: if the built-in battery does not supply power, the controller is not normally connected and is not detached;
s3: if the built-in battery supplies power, performing removal detection;
s4: if the built-in battery supplies power, whether external power supply exists needs to be detected. If the external power supply exists, the controller is not detached;
