摘　　要：在嵌入式机器人中,包含大量重要的运行数据,这些数据需要连接到网络上进行通信和传输,使其容易受到多种网络攻击;如果这些数据被篡改则会导致机器人无法正确执行任务,造成安全隐患;因此,为了确保数据的完整性和安全性,设计基于区块链的嵌入式机器人运行数据防篡改传输控制系统;在嵌入式主控板电路的配合下,协调机器人运行数据解算模块、传输数据矫正模块、控制系统微处理器之间的实时连接关系,完成传输控制系统硬件部分设计;设计控制系统环境和角色对象,并根据不同角色身份,确定运行数据在区块链RBAC组织中的访问能力,基于区块链中的哈希值实现对运行数据防篡改链码的恢复处理,完成基于区块链的嵌入式机器人运行数据防篡改方案的设计;提取运行数据中的关键嵌入部分,建立防篡改要求下的机器人运行数据聚集索引,计算篡改率数值,并实施针对性控制,完成基于区块链的嵌入式机器人运行数据防篡改传输控制系统设计;实验结果表明,经过上述系统的防篡改控制作用后,数据传输效率明显提高,非关联信息难以入侵嵌入式机器人运行系统,也无法篡改关键传输数据,有助于保障机器人运行数据的安全性。In embedded robots,there is a large amount of important operational data,which needs to be connected to the network for communication and transmission,making them vulnerable to various network attacks.If these data are distorted,it will cause robots to be unable to correctly perform tasks,resulting in security risks.Therefore,in order to ensure the integrity and security of data,an embedded robot operation data transmission control system based on blockchain is designed to prevent tampering.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 blockchain RBAC organization based on different role identities.Based on the Hash value in blockchain,implement the recovery processing of anti tampering chain codes for running data,and complete the design of the embedded machine s anti tampering data scheme based on blockchain.Extract the key embedded parts from the running data,establish the robot running data aggregation index under anti tampering requirements,calculate the tampering rate value,implement the targeted control,and complete the design of the embedded robot running data anti tampering transmission control system based on blockchain.Experimental results show that after the anti tampering control effect of the above system,the data transmission efficiency is significantly improved.It is difficult for non associated information to invade the embedded robot operating system,it cannot be tampered with critical transmission data,which helps to ensure the security of robot operating data.
