With the development of smart grids

high requirements are placed on distribution networks. Distribution network communication systems are an important part of distribution networks and an important factor affecting the development of distribution networks. Improving the terminal online rate is the key to the stable operation of the distribution network communication system. Due to the access mode and management issues

it affects the online rate of the terminal equipment and restricts the development of the distribution network. This paper discusses the terminal online rate drops from the aspects of terminal access mode and management

optimizes the terminal access mode and proposes the management method for the distribution network communication system

which improves the terminal online rate

and the stability of distribution network communication system

and promotes intelligent matching power grid development.
