According to an embodiment of the present application, there is provided a tamper-proof method for a T-BOX controller, as shown in fig. 1, the method including: the method comprises the following steps:

After the alarm, the method further comprises the following steps: and sending the current position to a server.

The alarm comprises alarm modes such as alarm sound, alarm short message and the like. And software prompting and the like of the user terminal can be used.

Next, embodiments of examples of the present application will be further described with reference to fig. 2 and 3.

Fig. 2 is a circuit diagram according to an embodiment of the present application. The coding input end of the priority decoding circuit is sequentially connected with pull-up resistors R and VCC through a phase inverter, a T-BOX controller and numbered fastening screws are connected with corresponding coding input pins through conducting wires, the coding output end of the priority decoding circuit is connected with an I/O port of an MCU, and the chip priority coding output end of the priority decoding circuit is connected with an interrupt pin of the MCU.

Assuming that the shell of the T-BOX controller is provided with 6 screws, when the production of the T-BOX controller is completed, the 6 fastening screws are all contacted with respective springs at the bottom, the springs are connected with GND, at the moment, the input of the priority decoding circuit is all high level, the input pin of the interrupt system is high level, and the disassembly sequence of the fastening screws is not detected.

When any fastening screw is unscrewed and disconnected from GND (ground), at the moment, the input of the priority decoding circuit is changed into low level, the output end of the chip priority code is also changed into low level, the interruption of the MCU is triggered, the system starts to detect and judge the disassembly sequence of the fastening screw, and the system immediately alarms when only 1 fastening screw is not consistent with the originally specified disassembly sequence (disassembly sequence code).

As shown in FIG. 3, it is assumed that the original disassembly sequence of the fastening screws is 1-5-3-6-2-4, i.e., the screw with position number 1 (the screw with position number 1) is disassembled first, the screw with position number 2 is disassembled second, and so on, and the screw with position number 4 is disassembled last.

When the 1 st disassembled screw is not the 1 st screw, the system gives an alarm. If the 1 st disassembled screw is exactly the 1 st screw, the system does not give an alarm, but the system continues to detect the position number corresponding to the disassembled screw, and if the disassembled screw is not disassembled according to the sequence of 1-5-3-6-2-4, the system sends out an alarm sound and an alarm short message as long as an error exists, so that the aim of protecting the controller from being illegally disassembled is fulfilled. When an alarm is given, the system will continue to detect the current detachment. If the screws are all installed back to the T-BOX controller and tightened, the system stops alarming.

The disassembly sequence codes of the controller screws are randomly generated and stored in a memory inside the system during production offline, and are uploaded to a server at the same time, and can be authorized to use when needed.

After the screws of the T-BOX controller shell are removed according to the disassembly sequence code, the T-BOX controller can update the disassembly sequence code. And deleting the current disassembly sequence code and saving the new disassembly sequence code.

The T-BOX controller sends a message to the server through the sending and receiving module, and the server sends a new disassembly sequence code to the T-BOX controller after receiving the message.

In a second aspect, the present application provides a tamper-resistant system for a T-BOX controller, as shown in fig. 4, comprising:

the priority decoding circuit 101 is respectively connected with each screw of the T-BOX controller shell and is used for detecting the position number of the disassembled screw of the T-BOX controller shell;

the MCU102 is connected with the priority decoding circuit and used for comparing the position number with the disassembly sequence code to obtain a comparison result; and executing a corresponding strategy according to the comparison result.

Further, the embodiment of the present application further includes:

the alarm module is connected with the MCU and used for alarming;

the positioning module is connected with the MCU and used for positioning the current position;

and the transmitting and receiving module is connected with the MCU and used for receiving the disassembly sequence codes and transmitting the current position to the server.

The sending and receiving module is also used for sending information of the disassembly completion to the server and informing the server to send a new disassembly sequence code to the T-BOX controller.

The transmitting and receiving module includes: a General Packet Radio Service (General Packet Radio Service) module, a 4G module and/or a 5G module, etc.

The disassembly sequence code can be stored in the memory of the MCU, and also can be stored in other memory modules.

In a third aspect, the present application is directed to a T-BOX controller, including a tamper-resistant system for the T-BOX controller.

In a fourth aspect, the present application is directed to a motor vehicle comprising a T-BOX controller having a T-BOX controller tamper resistant system mounted thereto.

In the method, the position number of a disassembled screw of a T-BOX controller shell is detected; comparing the position number with the disassembly sequence code to obtain a comparison result; and according to the comparison result, executing a corresponding strategy, and effectively preventing the T-BOX controller from being illegally disassembled. And the T-BOX-based hardware module detects and judges the disassembly sequence of the fastening screws, thereby protecting the controller from being illegally disassembled and preventing the internal data from being illegally modified.
