[0002] With the development of electronic technology, automobiles are equipped with an increasing number of electronic devices, and these devices can perform a wider range of functions. Currently, there is a type of in-vehicle equipment that, once installed on a designated vehicle, cannot be removed or installed without authorization. Examples include GPS tracking devices on commercial vehicles. This type of in-vehicle equipment includes the intelligent in-vehicle terminal TBOX, which has a built-in 4G SIM card, GPS module, wireless 4G communication module, and automotive CAN data acquisition bus. It is mainly installed in logistics vehicles, taxis, buses, etc., to monitor commercial vehicles according to regulations, providing vehicle operation data, battery and engine status monitoring, and fault warnings to OEMs or government departments. It can also provide vehicle owners with remote vehicle monitoring, remote diagnostics, and remote control services. Because the purpose of these in-vehicle devices is to monitor the operating status of commercial vehicles, some drivers or companies, seeking illegal profits, often remove these devices and install them on other vehicles to cover up their illegal activities. Summary of the Invention

[0003] The technical problem to be solved by the present invention is that current vehicle-mounted devices cannot detect whether they have been removed, and cannot issue warning information in a timely manner when they are removed. In order to solve this technical problem, the present invention provides a method for detecting the removal of a vehicle-mounted device, a vehicle-mounted device, and a readable storage medium.

[0004] To solve the above-mentioned technical problems, the present invention provides a method for removing and detecting a vehicle-mounted device, the method comprising:

[0005] When the circuit connecting the vehicle-mounted device to the car is detected to be disconnected, a removal alarm message is sent to the server.

[0006] When the vehicle-mounted device is detected to have reconnected to the circuit, the second device information of the current access terminal is read;

[0007] The operating status of the vehicle-mounted device is controlled based on the second device information.

[0008] Optionally, before detecting that the circuit connecting the on-board unit to the vehicle is disconnected, the method further includes:

[0012] When the second device information is the same as the first device information, the operating state of the vehicle-mounted device is controlled to be the normal operating state.

[0013] Optionally, after controlling the operating state of the vehicle-mounted device based on the second device information, the method further includes:

[0014] When the vehicle-mounted device is in an abnormal working state, it sends the latest working status to the server at preset time intervals.

[0015] Optionally, when the vehicle-mounted device is in an abnormal working state, it receives setting information sent by the server and adjusts the setting parameters of the vehicle-mounted device according to the setting information.

[0016] Optionally, when the reconnection of the vehicle-mounted device to the circuit is detected, the method further includes:

[0017] Obtain the setting status information of the vehicle-mounted device;

[0018] When the setting status information is in the initial state, the second device information of the current access terminal is read and the second device information is saved in the vehicle device;

[0019] The vehicle-mounted device is controlled to operate normally based on the second device information.

[0020] Optionally, the circuit connecting the on-board device to the vehicle includes at least one of a power supply circuit and a CAN data bus.

[0021] Optionally, the first device information and the second device information include at least one of the following: vehicle identification number (VIN), location information, license plate number, and vehicle status information.

[0022] Furthermore, the present invention also provides a vehicle-mounted device, the vehicle-mounted device comprising: a vehicle-mounted functional module, a detection module, a communication module, and a storage module.

[0024] The detection module is used to detect the connection status between the vehicle-mounted device and the circuit; when the detection module detects that the circuit connecting the vehicle-mounted device to the car has been disconnected, the communication module sends a disconnection alarm message to the server; when the detection module detects that the vehicle-mounted device has been reconnected to the circuit, the vehicle-mounted function module reads the second device information of the current access end; the vehicle-mounted function module controls the working status of the vehicle-mounted device according to the second device information.

[0025] Furthermore, the computer-readable storage medium stores one or more programs, which can be executed by one or more processors to implement the steps of the removal detection method for a vehicle-mounted device as described in any one of the above descriptions.

[0026] Beneficial effects

[0027] This invention provides a method for detecting the removal of an in-vehicle device, the in-vehicle device itself, and a readable storage medium. The method includes: sending a removal alarm to a server when the circuit connecting the in-vehicle device to the vehicle is detected as disconnected; reading second device information of the currently connected end when the in-vehicle device is detected as reconnected to the circuit; and controlling the operating state of the in-vehicle device based on the second device information. By detecting the circuit connection status between the in-vehicle device and the vehicle, it is possible to quickly determine whether the in-vehicle device has been removed and promptly send a removal alarm to the server for reminder. When the in-vehicle device is reconnected to the circuit, the second device information of the currently connected end is automatically read to determine the identity of the second device, thereby determining the operating state of the in-vehicle device. This achieves timely alarm when the in-vehicle device is removed and restricts the operating state of the in-vehicle device when installed on other vehicles. Attached Figure Description

[0033] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0034] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustrative purposes and has no specific meaning in itself. Therefore, "module," "part," or "unit" may be used interchangeably.

[0035] First Embodiment

[0036] Figure 1 This is a basic flowchart of a method for removing and detecting a vehicle-mounted device provided in this embodiment. The method for removing and detecting a vehicle-mounted device includes:

[0037] S101. When it is detected that the circuit connecting the vehicle-mounted device to the car has been disconnected, a removal alarm message is sent to the server.

[0038] Since all in-vehicle devices need to be connected to the car's power supply and computer, the connection circuit between the in-vehicle device and the car must be disconnected in order to remove the in-vehicle device. When the circuit connecting the in-vehicle device and the car is detected to be disconnected, a removal alarm message is sent to the server. After the staff in the server backend sees the removal alarm message, they can confirm with the car driver.

[0039] S202. When the vehicle-mounted device is detected to be reconnected to the circuit, read the second device information of the current access terminal.

[0040] Once the on-board unit is reconnected to the car's circuitry, it will automatically read the information of the second device at the current connection point through the connected circuitry.

[0041] S103. Control the working status of the vehicle-mounted device according to the second device information.

[0042] In some situations, such as poor contact due to road bumps, or temporary disconnection of the vehicle-mounted device from the vehicle's electrical system during car repair and inspection, the driver can communicate with the back-end staff, generally eliminating the need for on-site verification and reducing workload. When the vehicle-mounted device is detected as being reconnected to the circuit, the system reads the information from the second device at the current connection point and determines the device's specific operating status based on this information. For example, if the second device information matches the original vehicle information, it indicates a temporary power outage, and the vehicle-mounted device remains installed in the original vehicle and can operate normally.

[0043] In another embodiment, before the circuit connecting the vehicle-mounted device to the vehicle is disconnected, the method further includes: reading first device information of the current access point and storing the first device information in the vehicle-mounted device.

[0044] See also Figure 2 , Figure 2 This embodiment provides another method for detecting the removal of a vehicle-mounted device. Before step S101, it further includes step S100: reading the first device information of the current access terminal and storing the first device information in the vehicle-mounted device.

[0045] Since the vehicle-mounted device in this embodiment needs to determine whether the vehicle connected to the current access terminal is the vehicle corresponding to the vehicle-mounted device based on the device information of the access terminal at that time when it accesses the circuit again, when the vehicle-mounted device is in normal working condition, it needs to read the device information of the current access terminal on the currently connected car and save the device information of the current access terminal in the vehicle-mounted device as comparison information for the vehicle information obtained in the next access.

[0046] In another embodiment, controlling the operating state of the vehicle-mounted device according to the second device information includes: when the second device information is different from the first device information, controlling the operating state of the vehicle-mounted device to be an abnormal operating state; when the second device information is the same as the first device information, controlling the operating state of the vehicle-mounted device to be a normal operating state.

[0047] When the vehicle-mounted device reconnects to the circuit and the second device information read from the current connection end is the same as the first device information stored in the vehicle-mounted device, it means that the vehicle connected to the vehicle-mounted device again is the original vehicle. At this time, the vehicle-mounted device can be controlled to enter the normal working state.

[0048] When the vehicle-mounted device reconnects to the circuit and the second device information read from the current connection point is different from the first device information stored in the vehicle-mounted device, it indicates that the vehicle connected to the vehicle-mounted device may not be the original vehicle. At this time, the vehicle-mounted device can be controlled to enter an abnormal working state. This abnormal working state includes, but is not limited to, a stopped working state, an alarm state, and a locked state.

[0049] In another embodiment, after controlling the working state of the vehicle-mounted device according to the second device information, the method further includes: when the working state of the vehicle-mounted device is in an abnormal working state, sending the latest working state to the server at preset time intervals.

[0050] When the vehicle-mounted device enters an abnormal working state, it indicates that the device has been installed on another vehicle, the device has malfunctioned, or the vehicle itself has broken down. In this case, relevant personnel need to go and confirm the situation. To prevent back-end staff from missing messages, the latest working status needs to be sent to the server at preset time intervals. This preset time interval can be set according to actual needs, such as every 10 minutes, every half hour, or every hour.

[0051] In another embodiment, when the vehicle-mounted device is in an abnormal working state, it receives setting information sent by the server and adjusts the setting parameters of the vehicle-mounted device according to the setting information.

[0052] In some cases, such as when a vehicle-mounted device enters an abnormal working state due to a malfunction of the device or the vehicle, after confirmation that it is a device malfunction or a vehicle malfunction, the server can send setting information to the vehicle-mounted device to temporarily adjust the setting parameters of the device.

[0053] In another embodiment, when the reconnection of the vehicle device to the circuit is detected, the method further includes: acquiring the setting status information of the vehicle device; when the setting status information is in an initial state, reading the second device information of the current access terminal and storing the second device information in the vehicle device; and controlling the working state of the vehicle device to a normal working state according to the second device information.

[0054] See also Figure 3 , Figure 3 Another method for removing and detecting a vehicle-mounted device provided in this embodiment includes the following steps:

[0055] S301. When it is detected that the circuit connecting the vehicle-mounted device to the car has been disconnected, a removal alarm message is sent to the server.

[0056] S302. When the vehicle-mounted device is detected to be reconnected to the circuit, the setting status information of the vehicle-mounted device is obtained.

[0057] S303. Determine whether the setting status information is in the initial state. If yes, proceed to step S304; otherwise, proceed to step S306.

[0058] S304. Read the second device information of the current access terminal and save the second device information in the vehicle-mounted device.

[0059] S305. Control the working state of the vehicle-mounted device to normal working state according to the second device information.

[0060] S306. Read the information of the second device at the current access point.

[0061] S307. Control the working status of the vehicle-mounted device according to the second device information.

[0062] Step S303: Determine whether the setting status information is in the initial state. The purpose is to re-verify the vehicle device in some situations, such as when the vehicle device is recycled or repaired, so that it is restored to the initial setting state. When the vehicle device is connected to the circuit again, the setting status information of the vehicle device needs to be confirmed.

[0063] In other embodiments, the circuit connecting the on-board device to the vehicle includes at least one of a power supply circuit and a CAN data bus. Common circuit connection methods when an on-board device is connected to the vehicle's circuitry include a power supply link connection and a CAN data bus. The CAN data bus is used to connect to the on-board computer, thereby obtaining more useful information from the vehicle.

[0064] In other embodiments, the first device information and the second device information include at least one of the following: vehicle identification number (VIN), location information, license plate number, and vehicle status information.

[0065] This embodiment (beneficial effects).

[0066] This embodiment provides a method for detecting the removal of an in-vehicle device, including: sending a removal alarm to a server when the circuit connecting the in-vehicle device to the vehicle is detected as disconnected; reading the second device information of the currently connected end when the in-vehicle device is detected as reconnected to the circuit; and controlling the working state of the in-vehicle device based on the second device information. By detecting the circuit connection status between the in-vehicle device and the vehicle, it is possible to quickly determine whether the in-vehicle device has been removed and promptly send a removal alarm to the server for reminder. When the in-vehicle device is reconnected to the circuit, the second device information of the currently connected end is automatically read to determine the identity of the second device, thereby determining the working state of the in-vehicle device. This achieves timely alarm when the in-vehicle device is removed and restricts the working state of the in-vehicle device when it is installed on other vehicles.

[0067] Second Embodiment

[0068] This embodiment uses the TBOX vehicle terminal as an example to illustrate the technical solution of this invention.

[0069] A switch button is installed on the TBOX vehicle terminal. This switch button is used to detect whether the TBOX vehicle terminal has been disconnected from the circuit and whether it has been reconnected to the circuit. After the TBOX is installed in the vehicle and officially used after being verified by the platform, the vehicle identification number (VIN) is read through the CAN data bus and stored in the vehicle terminal. If it is removed once, the switch will automatically turn on and immediately report the removal information to the remote platform. At the same time, the removal information is saved in the vehicle terminal's storage area. When it is installed and used in another vehicle, if a different VIN is found, the vehicle terminal will first read the locally stored information to determine whether it has been removed, and then combine the information with the VIN read by CAN to determine whether it is the original vehicle. If it is not the same vehicle, the vehicle terminal will not work.

[0070] In other cases, if the new vehicle identification number cannot be read on a vehicle without a CAN bus, the on-board terminal will stop working directly, which can effectively prevent the aforementioned false reporting of mileage.

[0071] If the TBOX vehicle terminal is intentionally removed and then reused in another new energy vehicle, the regulatory authorities can simply re-flash the firmware and adjust the relevant parameter settings to restore it to its initial state.

[0074] The vehicle-mounted function module 51 is used to implement the functions required by the vehicle-mounted device 50 and control the vehicle-mounted device 50 to enter the corresponding working state.

[0075] The communication module 53 is used to enable communication between the vehicle-mounted device 50 and the server;

[0076] The storage module 54 stores one or more programs, which can be executed by one or more processors to implement the steps of the vehicle-mounted device removal and detection method described in this application.

[0077] The detection module 51 is used to detect the connection status of the vehicle-mounted device 50 with the circuit; when the detection module 52 detects that the circuit connecting the vehicle-mounted device 50 to the car has been disconnected, the communication module 53 sends a disconnection alarm message to the server; when the detection module 52 detects that the vehicle-mounted device 50 has been reconnected to the circuit, the vehicle-mounted function module 51 reads the second device information of the current access terminal; the vehicle-mounted function module 51 controls the working status of the vehicle-mounted device 50 according to the second device information.
