Research and development of movable dc power supply device based on micro-UPS module
Seismic station instruments have high precision,strong sensitivity,and are more vulnerable to lightning strikes.As the AC power supply of observation instruments is prone to lightning strikes,DC power supply is adopted to protect the stable operation of the instruments.Due to the serious radiation interference caused by close-range battery charging,the high frequency of battery replacement,the inability to estimate the battery power,and the problems caused by switching of batteries,the instrument is disconnected.It interferes greatly with the continuity and data accuracy of seismic observation instruments and seriously affects the validity of data.Aiming at the problems existing in the DC power supply of the instrument,a portable DC power supply device is designed based on the micro-UPS module and the related module of the power monitoring indicator.The results of several experiments show that:The successfully developed device can ensure that the battery replacement cycle is extended from 7 days to more than 15 days,the battery is carried by manual to trolley,and the instrument can provide uninterrupted power supply when the DC power supply is switched.the device can improve the stability and utilization rate of instrument observation data,and can be widely used in DC power supply instruments and equipment of similar seismic stations.
