Abstract: In order to improve the real-time performance of smart distribution network equipment address recognition search, solve the fast address search problem of distribution network intelligent equipment or device or unit, application Fibonacci method for two segments division of the address segment, this paper proposes a quick address search method for identification and lookup of the distribution network equipment. Aiming at the problem of search and query in the MAC (Media Access Control) address, IPv4 (Internet Protocol version 4) address or IPv6 (Internet Protocol version 6) address space of the equipment / device / unit in the distribution network, the computer simulation results show that compared with the midpoint method, the address lookup speed of the method is faster. It can improve the real-time performance of the intelligent perception of the distribution network and speed up the network management response speed of the equipment / device / unit failure in the distribution network. The operation and maintenance performance of the distribution network are improved, and the security and intelligence level of the distribution network system are promoted.
