Digital geological compass and method for measuring geological occurrence

Abstract

The invention provides a digital geological compass and a method for measuring geological occurrence, an azimuth angle and inclination angle data acquisition module, a laser module, a power supply circuit and a display module respectively connected to a storage and control module are provided in a casing; the azimuth angle and inclination angle data acquisition module comprises a magnetic sensor, an acceleration sensor and an A / D converter; the storage and control module reads the azimuth angle and inclination angle data measured by the azimuth angle and inclination angle data acquisition module, a pitching angle and a roll angle are obtained, the azimuth angle, the pitching angle and the roll angle data are sent to the display module for displaying and storing when necessary. The digital geological compass and the method for measuring geological occurrence have the advantages of high precision, convenient operation and high efficiency, and have angle compensation function by using a three-dimensional (shaft) technology when the azimuth angle is read, the real-time reading under compass horizontal are not necessary, so that the operation time can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of geological compass and relates to a digital geological compass and a method for measuring the occurrence of geological bodies. Background technique [0002] At present, geological compasses are designed with mechanical pointers, which are often used to measure the azimuth (strike, dip) and dip of various geological structures. This compass has the following disadvantages: [0003] (1) Large errors in measurement accuracy: For example, when measuring azimuth, it is necessary to maintain a relative level first, which requires observing the centered balance of the mercury bubble used to measure the level. There will be observation errors due to the vibration generated by the hand-held compass. When reading the data after the relative level or reading the center value of the pointer drift or manually controlling the pointer to stop swinging, there will also be an error of at least 1-3 degrees at this time, a...

AI Technical Summary

Problems solved by technology

When reading the data after the relative level or reading the center value of the pointer drift or manually controlling the pointer to stop swinging, there will also be an error of at least 1-3 degrees at this time, and the accumulation of the aforementioned errors will produce a larger error

However, when the mechanical parts are aging and the operating environment is harsh, the error of the traditional compass will be greater

When measuring the inclination, you need to obtain the horizontal direction first, which will also cause a large error;

[0004] (2) Low operating efficiency: the traditional compass is time-consuming due to the aforementioned maintenance of the balance of the mercury bubble and the observation of the pointer balance during measurement, and it often needs to be repeated many times to obtain more accurate data; the above process also needs to be repeated when measuring the inclination angle. Therefore, it takes a relatively long time, which is a very obvious deficiency in the use of this compass under the harsh or even unsafe conditions in the mine.
