| 内容記述 | We have developed an uninterruptible power supply (UPS) systems suitable for permanent seismic stations, and have used it to replace commercial UPS systems at seismic stations belonging to the Daidaitoku seismic network. For use in seismic stations, the newly developed UPS system offers several advantages over the commercial UPS systems that are often used to protect personal computers from a sudden power failure. First, independent cut-off voltages can be set for two different output circuits, one for an ISDN router and the other for a seismometer and data logger. In addition, DC power can be supplied using a battery, and the efficiency is improved by about two times. Finally, the new UPS is more compact, which allows easier handling at stations. When a battery with a capacity of 40 Ah is used, the newly developed UPS is designed to supply continuous electric power to equipment for seven days after a commercial power failure. To achieve this, the power to the ISDN router, which represents approximately 70% of the total power, is automatically turned off about two days after the power failure occurs. The power supply to the data logger and seismometer is maintained until the battery voltage reaches a preset lower limit, in order to prevent deep discharge. If the commercial power supply is restored at the station, all systems are restarted and the battery is automatically recharged. After being installed in the Daidaitoku seismic network, the new UPS systems functioned without any problems. Therefore, the power system in seismic stations can be successfully upgraded in this manner. | |||||
