Abstract:
To ensure the stable operation of Anhui's seismic monitoring network, a comprehensive review of the operational status of 31 participating stations from 2020 to 2024 was conducted. By analyzing station uptime rates, fault frequency, and cumulative downtime, the operational efficiency of stations was reasonably evaluated. Common faults were categorized into four major types and twelve subcategories: communication systems, power supply systems, observation instruments, and other factors. Analysis indicates that over the past five years, 29 of the 31 evaluated stations maintained an annual average operational rate exceeding 99%. The vast majority of faults were detected and resolved within 24 hours, demonstrating overall sound operation of the observation systems. Power supply and communication system failures constitute the primary fault types affecting seismic observation stations, accounting for 73% of all incidents. Recommendations include: Developing an AI-powered station operation and maintenance model and an online fault diagnosis platform to automate fault alerts, rapid diagnostics, and solution generation. - Strengthening duty shifts during July-September and implementing proactive lightning and flood prevention measures. - Provincial operation centers should optimize spare equipment allocation strategies and enhance grassroots personnel's maintenance capabilities.
