Abstract: In view of existence of high temperature and high energy consumption during borehole trajectory measurement in mines, the paper puts forward an storage inclinometer with intermittent power supply without cable, MEMS gyroscope and accelerometer were used in hardware, for software measures of anti-interference, error correction, and temperature compensation were taken. It can be used in hole-forming measurement for monitoring geological hazards, recording azimuth, inclination angle, tool face angle, hole depth and other altitude parameters. After the measurement, the computer reads data, displays the trajectory patterns. Through simulation and simulation test, the inclinometer has low power consumption, small volume, high measuring precision, good stability, etc.
