[0002] The operating status data of power equipment is usually sent to the dispatching command center through optical fiber, wireless communication and other networks. This single ground network communication mode has the following problems: First, the ground communication network signal is easily affected by environmental interference, especially when disasters such as earthquakes, landslides, mudslides, floods, etc. occur, the ground communication network cannot provide timely communication, resulting in signal transmission interruption, and it is impossible to obtain power equipment operating status information throughout the day and across the entire region; second, for remote areas, areas where optical fiber networks and wireless communications are not covered, there is a problem of inconvenient terminal access; third, the existing method of using satellites to realize data transmission can only transmit data within the single communication capacity of Beidou short messages. Data that exceeds the single capacity cannot be transmitted, and timestamp information cannot be added to the data. Due to the large transmission delay of Beidou short messages, the time synchronization of data transmission and reception cannot be guaranteed. Summary of the invention
