Abstract: With the increase in the number of earthquake stations and the scaling up of unmanned stations, the traditional operation and maintenance mode of stations is facing challenges such as frequent power supply, communication, and instrument failures. In order to improve the quality of monitoring data and reduce the pressure of operation and maintenance work, the Hebei Provincial Seismological Bureau relies on the Catastrophe Prevention Project to implement intelligent upgrades of seismic stations throughout the province. An intelligent guarantee technology system for the normal operation of the station observation system has been constructed by integrating 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 to ensure continuous power supply in case of power interruption in the city; Switch optimization for network communication stability; The camera monitors the device status and environmental safety in real-time. Through intelligent upgrades, remote alarms for abnormal power supply at stations and power outages and restarts of web terminals have been achieved, effectively shortening the time for fault recovery; Reliable operation of network communication equipment ensures data communication, combined with the intelligent power management platform of the network center to achieve unified monitoring of station operation and maintenance throughout the province. Practice has shown that intelligent upgrades have effectively improved the continuous operation capability, maintenance efficiency, and observation data continuity of station equipment, providing strong technical support for the reliability and timeliness of the earthquake monitoring and early warning network in Hebei Province.
