Abstract: Based on state perception, considering the dynamic and static data of communication equipment, combined with the experience of operation and maintenance management, using historical and real-time data such as historical defects and maintenance, current performance value and state value, this paper focuses on the research on the influence of operation environment and equipment state key parameters on the life of transmission equipment. We construct the health state evaluation model and its algorithm in order to perceive the current state of communication transmission equipment and realize the health status evaluation and the influence of various parameters on life. The research results can guide the operation, maintenance and technical reform of equipment, reasonably build and adjust the communication network, provide support for the whole life cycle management of power communication transmission equipment, and improve the management level of communication operation.

Key words: health status of communication transmission equipment, remaining life, charge and discharge
