The application of intelligent power management system in engineering seismograph

The paper presents a kind of intelligent power management system used in engineering seismograph, which consists of power supply circuit based on power module, and power monitoring circuit based on high speed single chip microcomputers (SCM) C8051F320 and 24-digits high-precision analog-to-digital (A/D) converters LTC2449. The design has features such as wide input range, stable output, self protection, power monitoring and simple user interface etc.
