The coprocessor in the NXP chip simultaneously comprises Hitag2/Hitag3, 11,12,13 and other arithmetic logics, so that the NXP chip can be set as a common anti-theft chip which can be compatible with various vehicle types; the NXP chip is provided with two memories of an EEPROM and an Erom, the internal EEPROM is used for storing anti-theft data and is matched with an internal algorithm coprocessor of the chip to realize an anti-theft function, the internal Erom stores an anti-theft user program, the anti-theft user program comprises an anti-theft basic program and an anti-theft application program, the anti-theft basic program controls the NXP chip to enter a configuration mode or run the anti-theft application program, and the NXP chip can be configured with software in the configuration mode; the anti-theft application program realizes the anti-theft function adapting to different vehicle types.
Specifically, as shown in fig. 4, the data types of the base station interacting with the NXP chip may be classified into the following categories (for convenience of description, the initialization apparatus is referred to as the base station in the following description):
1) function instructions
The functional instruction is an instruction which is sent by the base station, received by the NXP chip and required to be executed by the NXP chip; the first byte of the functional instruction is a header; the second byte is an instruction name sent to the NXP chip by the base station; the intermediate data is specific operation data, and the length of the intermediate data is variable; the last 2 bytes are check bits for checking whether the instruction is legal.
2) End instruction
The end instruction is sent by the base station, the NXP chip receives the end instruction and requires the NXP chip to quit the interaction process with the base station; after the software configuration is completed or error reporting information of the NXP chip is received, the base station can send an ending instruction, and the length of the ending instruction is 1 byte.
3) Answer signal
In one embodiment, after receiving a first instruction or a second instruction sent by a base station, an NXP chip sends a response signal to the base station to indicate that a corresponding instruction is received;
the response signal is sent by the NXP chip and received by the base station; after receiving the functional instruction sent by the base station, the NXP chip first replies a response signal, which indicates that the command has been received, wherein the length of the response signal is 1 byte, and the bit sequence of the response signal is the inverse of the bit sequence of the received functional instruction.
4) Query instructions
In one embodiment, the NXP chip sends a response signal, the base station sends a query command at regular time after receiving the response signal, the NXP chip waits for the base station to query after completing a task, and replies base station data after receiving the query command, namely, returns a query result to the initialization device; the query instruction is used for querying whether the corresponding instruction is executed completely. The length of the query instruction is 1 byte.
The base station needs to send different instructions to the NXP chip in the process of completing software configuration, and because task completion time required by each instruction is unequal, if a method that the base station waits for the NXP chip to complete a task and then replies data is adopted, the base station needs to be in a waiting state all the time; however, if the reply data is acquired by adopting the base station timing query mode, on one hand, the base station can perform other work during the task corresponding to the key execution instruction, and on the other hand, after the key completes the task, the base station query can immediately respond, so that the real-time performance of the system is ensured.
5) Error reporting during operation
The operation error report is sent by the NXP chip and received by the base station; when receiving an illegal command or encountering read-write errors and other conditions in the running process, the NXP chip can send an error signal to the base station, so that the robustness of the system is ensured. In one embodiment, the bit sequence of the error signal is run at 0101010111111111.
6) Instruction recovery
The command reply is sent by the NXP chip, the functional command sent by the base station is received by the base station, and after the functional command is obtained, the functional command is replied to the base station through the command reply signal. The head of the command reply signal is 1 byte, the data of the middle part is variable, and the last 2 bytes are check bits according to specific functional commands.
According to the specific data types of the above interaction between the base station and the key, fig. 3 shows the interaction flow of the automobile key and the initialization device, and the base station sends corresponding instructions to the key to arrange the tasks of each step of the software configuration and obtains the current key state by receiving the response of the key. Specifically as shown in fig. 3. Firstly, the base station wakes up the key, and the key enters a configuration mode after confirming that the base station wakes up, and then the base station sends an instruction to the key and the key receives the instruction. The method comprises the steps that a base station sends instructions to a key, wherein the instructions comprise a functional instruction and other instructions such as an end instruction, the functional instruction comprises the first instruction and the second instruction, after the key receives the instructions, whether the instructions are the end instruction is judged, if yes, the key exits from the interaction process with the base station, namely exits from a configuration mode, and returns an operation result of exiting interaction to the base station; if the instruction is not the ending instruction, the key further judges whether the instruction is legal or not, if the judgment result is illegal, the key exits the interaction process with the base station, and if the judgment result is legal, the key executes the instruction. For example, when the instruction is a first instruction in the function command, the key executes the first instruction, the anti-theft authentication unit wakes up the remote control unit after receiving a digital signal converted from the first instruction, then forwards the digital signal to the remote control unit, the remote control unit sends the first identity authentication information to the anti-theft authentication unit after receiving the instruction, and the anti-theft authentication unit sends the first identity authentication information to the initialization device through the modulation and demodulation unit and the wireless radio frequency module. In the instruction executing process, if the NXP chip receives an illegal instruction or encounters the conditions of reading and writing errors and the like in the operation process, an error is reported to the base station to ensure the robustness of the system, the key feeds back the fault state to the base station, and the base station sends the instruction to the key again; if no error is reported in the execution process, the key replies the data to the base station after receiving the inquiry command of the base station, then executes the next command, and after the software configuration is completed, the base station sends an ending command to the key.
