Distribution automation, a key technology, is built on the basis of the power system distribution network. Through the comprehensive use of computer, information, and communication technologies, and deep integration with related application systems, it achieves real-time monitoring, precise control, and rapid isolation of faults in the distribution network. The distribution automation terminal, as an important component of this technology, refers to various remote monitoring and control units installed in the distribution network. They shoulder core tasks such as data collection, execution of control instructions, and communication transmission. According to different classification criteria, these terminal devices can be classified into station terminals (DTUs), feeder terminals (FTUs), distribution transformer terminals (TTUs), and distribution line fault location indicators. Meanwhile, according to their functional characteristics, terminals can be divided into those with "three remote" (remote signaling, telemetry, remote control) functions and those with only "two remote" (remote signaling, telemetry) functions. In addition, according to different communication methods, these terminals can be divided into two categories: wired communication terminals and wireless communication terminals.
