Research on distribution terminal software version control method based on DNA coding

Abstract: The distribution terminal software version controlled is important to the stable operation and observability of the distribution network, and there is a lack of effective supervision methods at present. This paper studies and implements a software version control method for distribution terminal, through analyzing the influence factors of executable file attributes, a priority factor matching model is constructed. By selecting two isomeric hash algorithms and using combinatorial fault safety thought, the collision probability is effectively reduced while the efficiency is guaranteed. Combined with the technology of random sequence and segmentation rotation rank, it extracts the DNA coding string which only represents the distribution terminal software identity, and realizes the effective and feasible identification, archiving and detection control process for the terminal software. The practical application shows that the method can effectively control the software version of the delivery terminal, avoid misoperation and human tampering, and the process is simple and reliable.
