The number of unmanned seismic monitoring stations is increasing together with an associated lack of operation and maintenance activities. This study puts forward use of a remote monitoring system based on a STC89C52 single chip microcomputer (SCM). The detection and control part of the system mainly includes a microcontroller, communication module, LCD character module, power supply module, reset circuit, and all types of sensors. Temperature and humidity are real-time collected and the SCM instructs the control relay to absorb and release. If an anomaly occurs at the station, the warning detection system transforms information into an abnormal event alarm command using a GPRS Modem; a command is then sent using a GSM communication link to the mobile phone of the person responsible for maintaining the instrument in the form of short message, providing references and decisions made. For example, if damage to equipment is not caused by the instrument, the GSM will issue a corresponding SMS command, which can lead to termination of power and restarting operation of the equipment using the device reset circuit. In contrast, if the instrument causes damage, a maintenance engineer is sent to repair the instrument. Based on the principle that intermediate relay is controlled by the SCM, the system can remotely reboot the industrial board power supply using the intermediate relay to drive the AC contactor. This solves problems such as that which occurred when the FHD-2B proton magnetometer at Yongan geomagnetic station, which was controlled by a PC104 industrial control computer, crashed repeatedly and the network interface RJ45 was continually blocked.
