Remote Monitor and Control System for Seismic Stations Based on STC89C52 Single Chip Microcomputer
摘要
Abstract
The number of unmanned seismic monitoring stations is increasing together with an as-sociated lack of operation and maintenance activities.This study puts forward use of a remote mo-nitoring system based on a STC89C52 single chip microcomputer (SCM).The detection and con-trol 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 anoma-ly occurs at the station,the warning detection system transforms information into an abnormal e-vent 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 instru-ment.Based on the principle that intermediate relay is controlled by the SCM,the system can re-motely reboot the industrial board power supply using the intermediate relay to drive the AC con-tactor.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.关键词
