n working principle

The YHZ90/360 intrinsically safe drilling rig opening directional instrument for mining is a new type of intelligent portable instrument for measuring the posture of drilling rigs. The instrument is equipped with a high-precision gyroscope and acceleration sensor. After alignment on the calibration platform, it can accurately measure the posture (azimuth and inclination) of the drilling rig. The measurement process is not affected by geomagnetic and ferromagnetic substances, overcoming the problem of inaccurate measurement caused by magnetic substances such as drilling rig, steel mesh, and anchor rod in the traditional address compass measurement process; The angle compensation algorithm has been adopted to overcome the defect of large azimuth error in similar devices when the inclination angle is greater than 85 °, achieving accurate measurement of azimuth and inclination angles within the full inclination range and measuring full coverage.
