In embedded robots, there is a large amount of important operational data that needs to be connected to the network for communication and transmission, making them vulnerable to various network attacks. If these data are tampered with, it will cause the robot to be unable to perform tasks correctly, resulting in security risks. Therefore, in order to ensure the integrity and security of data, a blockchain based embedded robot operation data tamper proof transmission control system is designed. With the coordination of the embedded main control board circuit, the real-time connection relationship between the robot operation data calculation module, transmission data correction module, and control system microprocessor is coordinated to complete the hardware design of the transmission control system. Design the control system environment and role objects, and determine the access capability of running data in the blockchain RBAC organization based on different role identities. Based on the hash value in the blockchain, implement the recovery processing of anti tampering chain codes for running data, and complete the design of an embedded machine"s anti tampering data scheme based on blockchain. Extract key embedded parts from the running data, establish a robot running data aggregation index under anti tampering requirements, calculate the tampering rate value, and implement targeted control to complete the design of an embedded robot running data anti tampering transmission control system based on blockchain. The experimental results show that after the anti tampering control effect of the above system, the data transmission efficiency is significantly improved. Non associated information is difficult to invade the embedded robot operating system, and critical transmission data cannot be tampered with, which helps to ensure the security of robot operating data.
