Problems solved by technology
[0003]The instructions of different products of the same MCU chip are interlinked. As the products using MCU chips become more and more diversified, for different products using the same MCU chip , does not achieve isolation in the communication protocol, even if two different products A and B use the same MCU chip, the instruction sent to product A is also valid to be sent to product B, which will lead to misexecution and affect normal operation. Communication process; in addition, the current MCU chip may be intercepted by MCUs of other products after the communication command is issued, which may cause information leakage
[0004]There is currently no solution for the shortcomings of existing technologies

The invention belongs to the technical field of communication systems, and particularly discloses an MCU communication system which comprises a data input module, a master control MCU chip module, a data transmission module, a slave control MCU chip module and a communication terminal which are sequentially connected. The data input module is used for inputting data information and transmitting the data information to the master control MCU chip module; the master control MCU chip module is used for receiving information input by the data input module and encrypting the information; the data transmission module is used for receiving the encrypted information and transmitting the encrypted information to the slave control MCU chip module; the slave control MCU chip module is used for receiving the encrypted information, decrypting the encrypted information and transmitting the decrypted information to the communication terminal; and the communication terminal is used for receiving the decrypted information and displaying the information to the display equipment. According to the invention, encrypted transmission of data information in the data transmission module is realized, information security can be guaranteed, and information theft is avoided.
Description
technical field [0001] The invention belongs to the technical field of communication systems, in particular to an MCU communication system and method. Background technique [0002] MCU is the abbreviation of Micro Control Unit, which has been widely used in different occasions, such as mobile phones, PC peripherals, remote controls, automotive electronics and artificial intelligence and other fields. [0003] The instructions of different products of the same MCU chip are interlinked. As the products using the MCU chip become more and more diversified, different products using the same MCU chip are not isolated in the communication protocol, that is, the same MCU chip is used. For two different products A and B of the chip, it is also effective to send the instruction sent to product A to product B, which will lead to misexecution and affect the normal communication process; in addition, after the current MCU chip sends out the communication instruction, It may be intercept...
