Abstract:To ensure the normal operation of seismic observation stations and solve the problems existing in the current system, such as the weak observation anti-interference ability, the inconsistency between the observation and actual results, the inefficient utilization of resources, and the inadequate working efficiency, using the combination of various techniques, an intelligent seismic observation system of unattended station information is designed. The system integrates equipment management, information collection, information communication, information management, and application. Considering the particularity of the working task of seismic observation stations, the required functions of the observation system are analyzed. To realize real-time monitoring, timely repair, and remote control, a 12 V stabilized DC power supply and a UPS with two channels are used as the power supply equipment of the observation system. A network communication system is integrated by adopting a wired and wireless dual-line backup mode, and a man-machine interaction design is realized. On this basis, the system software, including user management, on-duty work management, station equipment management, station operation state observation, fault early warning, and fault emergency repair are mainly designed. The performance test results show that the design system can maintain a continuous rate of information transmission when the network is interrupted, and the work efficiency is high. It has a strong anti-interference ability, stability, and reliability, and does not cause a large waste of resources.
