Development and Application of a Smart Monitoring and Transmission System for Seismic Stations

How to restore seismic observation signals as soon as possible when there is a failure in a seismic station's instrument or transmission channel has become a challenge that needs to be solved urgently in our seismic observation work. By taking enhanced single-chip microcomputer (SCM) as the core of hardware, and the third/fourth-generation (3G /4G) of industrial-level mobile communication modules as a communication bridge for information exchange, this study proposed an instrument that allows us to carry out real-time monitoring for a seismic station's equipment running status via its network interface and serial interface, thus realizing a remote control over the powering-up and restart of the equipment, and switching between the main equipment and standby equipment, meanwhile, when there is a failure in the transmission channel, the 3G/4G wireless data transmission function can be invoked so that seismic observation data can be transmitted timely to the seismic station network center, thus an uninterrupted transmission of seismic observation signals is ensured.
