Abstract

The invention discloses a rock stratum attitude measurement method based on intelligent mobile equipment. The main operating flow is to tightly attach the back surface of the intelligent mobile equipment to the surface of a rock stratum; a gravity acceleration component value under a mobile equipment coordinate system and an included angle between the Y axis of the mobile equipment coordinate system and the north-pole direction of a geomagnetic field are obtained through an acceleration sensor module and a direction sensor module of the intelligent mobile equipment. Due to the method, the direction, the inclination direction and the inclination angle of the rock stratum can be obtained. The method can be used for measuring the rock stratum attitude and also used for measuring attitudes of a structural surface of a rock body and a side slope surface.

Description

A kind of measuring core occurrence method based on Intelligent mobile equipment
Technical field
The present invention relates to geologic information compile and analyze application, more particularly, to a kind of attitude of rocks parameter The method obtaining and calculating.
Background technology
The occurrence of rock stratum is the general name in the state in space output for the rock stratum and orientation, and occurrence three elements table is generally used in occurrence Show, including the trend of rock stratum, tendency and inclination angle.Horizontal line on the intersection of rock stratum face and horizontal plane or rock stratum face i.e. this rock stratum Strike line, the direction of its two ends indication is the trend of rock stratum, can be represented by two azimuths differing 180 °.Capwise line Along dipping bed, drawn straight line is inclination of strata line downwards, and the aspect incline direction of the floor projection line indication of parallax is exactly The tendency of rock stratum, trend differs 90 ° with tendency.Angle between the parallax of rock stratum and its floor projection line is inclining of rock stratum Angle.
In prior art, typically measure the attitude of rocks with circumferentor.Concrete grammar is as follows:
1. the mensure of formation strike
Formation strike is level rock and the direction of horizontal plane intersection i.e. rock stratum is arbitrary highly goes up horizontal extension Direction.During measurement, long for compass side is close to aspect, then rotates compass, make the blister of chassis spirit level placed in the middle, read pointer Indication scale is the trend of rock stratum.
2. the mensure of rock stratum tendency
Rock stratum tendency refers to the projection in the horizontal plane of rock stratum downward maximum inclination line of direction, permanent vertical with formation strike. During measurement, by compass the North or connect thing board point to incline direction, the compass south nestles up aspect and rotates compass, makes chassis water Quasi- device blister is placed in the middle, reads the tendency that compass indication scale is rock stratum.
3. the mensure of formation dip
Formation dip is the maximum angle between level rock and imaginary horizontal plane, i.e. true dip angle, and it is true along rock stratum Incline direction measurement obtains.During measurement, compass is upright, and with long side against the true dip line of rock stratum, move along about aspect Swinging compass, and move the adjustable wrench of compass bottom with middle finger, makes deviational survey spirit level blister placed in the middle, reads in outstanding cone sharp indication Big reading, the as true dip angle of rock stratum.
As can be seen that the measurement of the attitude of rocks at least needs acquired tendency and inclination angle in above-mentioned measurement, at least to divide Carry out twice, and spirit level blister will be adjusted between two parties every time, this strike-dip survey method is comparatively laborious, work efficiency also compares Low.

Brief description
Fig. 1 is the flow chart of the present invention；
Fig. 2 is the coordinate schematic diagram of smart mobile phone.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples, but should not be construed subject of the present invention model Enclose and be only limitted to following embodiments.Without departing from the idea case in the present invention described above, according to ordinary skill knowledge And customary means, make various replacements and change, all should include within the scope of the present invention.
A kind of measuring core occurrence method based on Intelligent mobile equipment, comprises the following steps:
1) take a representative rock stratum face, rock layer surface is close at the mobile device back side.Described intelligent mobile sets Get everything ready and have acceleration sensor module (accelerometer sensor) and direction sensor module (orientation Sensor).In embodiment, described Intelligent mobile equipment is smart mobile phone.
2) by described acceleration sensor module, obtain gravitational acceleration component value a under mobile device coordinate systemx、ayWith az.
What deserves to be explained is: the natural system of coordinates of mobile device refers to be placed in the direction of its acquiescence when a mobile device When upper, x-axis is horizontally directed to the right side, and y-axis is vertically upward, and z-axis is directed to outside screen front, and that is, the screen back side is z Negative value.
, x-axis, y-axis and z-axis are existing in existing technology clearly to be defined, as Fig. 2 institute taking mobile phone natural system of coordinates as a example Show:
, parallel to horizontal (width of mobile phone) of mobile phone screen, y-axis is parallel to Mobile phone screen for the x-axis of described smart mobile phone , each parallel to mobile phone screen, z-axis is perpendicular to mobile phone screen for the longitudinal direction (length direction of mobile phone) of curtain, x-axis and y-axis；
