Abstract: With the increasing number of earthquake stations and scaling up of unmanned stations, the traditional operation and maintenance mode of stations is facing various challenges such as frequent power supply, communication, and instrument failures. To improve the quality of monitoring data and reduce the pressure of operation and maintenance work, Hebei Earthquake Agency relies on the catastrophe prevention project to implement intelligent upgrading of seismic stations across the entire province. An intelligent guarantee technology system for the normal operation of the station observation system has been constructed by integrating an intelligent power supply, battery pack, switch, and camera equipment. The intelligent power supply provides instrument power supply and remote monitoring, combined with the battery pack, it ensures continuous power supply in case of power interruption in the city and switch optimization for network communication stability, while the camera monitors the device status and environmental safety in real-time. Intelligent upgrading have enabled remote alarms for abnormal power supply at stations and power outages as well as restarts of web terminals, effectively shortening the fault recovery time. Reliable operation of the network communication equipment ensures data communication, which combined with the intelligent power management platform of the network center, achieves unified monitoring of station operation and maintenance across the entire province. In practice, intelligent upgradings have effectively improved the continuous operation capability, maintenance efficiency, and observation data continuity of station equipment, thereby providing strong technical support for the reliability and timeliness of the earthquake monitoring and early warning network in Hebei Province.
