| Abstract: |
| There are problems of difficulty in accessing a large number of heterogeneous sensors and in the time-delay of data processing and analysis and high data transmission bandwidth occupancy rate in the multi-state monitoring of substation equipment. This paper proposes a monitoring system for multiple state quantities of substation equipment based on edge-cloud collaboration. An edge cloud collaborative service architecture for the monitoring of substation equipment is designed. An edge computing device is developed. It supports multiple sensor protocol analysis, data collection and edge computing. It realizes the status evaluation and edge service of the substation equipment on the edge side, and carries out on-site application verification. The system provides new ideas for the condition monitoring of substation equipment and has high application value.
