Background
The roller cone drilling machine is main drilling equipment adopted in strip mine production, hole distribution is mainly performed on a tape of workers in the traditional roller cone drilling machine, holes are marked by using colored markers, and then a driver of the drilling machine searches for the holes according to driving experience. In addition, when the roller bit touches the underground extremely hard rock body in the drilling operation, if a driver continues to keep drilling, the drilling motor is always kept in a high-load running state, accidents such as motor damage and the like are easy to happen, and the abrasion of the drill bit is accelerated.
With the development of science and technology, some positioning methods for assisting drilling positioning of a drilling machine appear in the prior art, but the methods in the prior art mainly depend on the fact that GPS positioning is approximate to a plane, and positioning calculation is carried out by using plane geometry or a series of coordinate conversion and the like.
For example, the chinese patent publication No. CN102155212B discloses a roller cone drill throwing hole positioning instrument and a positioning method, in which two GPS antennas are used to sense the position of the drill and convert the position into an electrical signal to be transmitted to a signal acquisition resolver, a dual-inclination sensor is used to sense the inclination of the drill and convert the inclination into inclination pulse data to be transmitted to the signal acquisition resolver, and then the signal acquisition resolver resolves the electrical signal and the inclination pulse data to obtain a drill position coordinate, and simultaneously, the drilling depth can be measured.
The Chinese patent with the publication number of CN103343683B discloses a real-time perforation positioning method of a roller-cone drilling machine based on GPS, firstly, a perforation positioning model is constructed by utilizing a GPS, specifically, three control points are selected on a rotary drill platform, then real-time monitoring is carried out on the three control points by using RTK-GPS equipment, a real-time perforation positioning model of the rotary drill is obtained, plane coordinates of perforation points of the rotary drill are obtained by using a three-point space rear intersection method, the perforation depth of the rotary drill is calculated through the elevation change of the control points, the method improves the positioning precision, but the conversion process is relatively complex, and three RTK-GPS devices need to be arranged on the rotary drill rig, so the device cost is also improved, in addition, the method can only prompt the driver whether the drilling is finished or not by displaying the drilling depth, and when the driver encounters a hard rock stratum, the driver still cannot know and adjust the drilling in time.
Also, for example, chinese patent publication No. CN105320831B discloses a method for realizing real-time high-precision positioning of a drill rod of a surface mine drilling machine, which uses two high-precision GPS and an electronic compass device installed on the drilling machine to perform positioning, and the method obtains relationship values between two GPS coordinate points, the drill rod point and the electronic compass in a horizontal state of the drilling machine, and finally realizes high-precision positioning of the drilling machine through processes of coordinate translation, three-dimensional and two-dimensional space coordinate conversion, mathematical modeling, and the like.

the method comprises the following steps: the distance L between the main measuring antenna 3 and the drill rod 11, namely ZA L, is measured in advance, and the included angle theta between ZA and BA is measured 2 。
In addition, as described in the background art of the CN105320831B patent, in the prior art, a GPS drill rod is used for positioning, and two methods are mainly used, one is that two GPS antennas are on the same straight line with the drill rod, and the other is that the drill rod and two GPS antennas form an isosceles triangle, and due to the complex structure of the drilling machine, it is often difficult to find a proper position for installation by using the above method, but as shown in fig. 1, the position a of the main measurement antenna 3 and the position B of the auxiliary measurement antenna 4 can be installed at proper positions according to the structural condition of the roller drilling machine, and are not limited by the structure of the roller drilling machine.

In actual operation, a driver needs to be assisted in aligning holes, the moving posture of the current drilling machine needs to be known, and the posture is determined by the included angle between the current drilling machine and the due north direction.
Step four: according to L obtained in the first step and theta obtained in the third step 1 Calculating the distance X between the drill pipe 11 and the position A of the main measuring antenna 3 in the longitude direction lon And the distance Y between the drill rod 11 and the position A of the main measuring antenna 3 in the latitudinal direction lat ：
X lon ＝L×sin(θ 1 )；
Y lat ＝L×cos(θ 1 )。
Step five: as shown in fig. 3, the spherical radius rb of the latitude at the position a of the main measuring antenna 3 is calculated by the following formula (a):

the above equations (1) and (2) are the longitude and latitude calculation in geography, which is a technique well known in the art.
Step seven: the longitude D of the drill rod 11 is obtained according to the following formula (c) LON (°)：
Figure BDA0003754583200000082
In the above formula (3):
Figure BDA0003754583200000083

Figure BDA0003754583200000084
is the radian value of the converted longitude of the point A;
the two camber values are added up and multiplied by
Figure BDA0003754583200000085
Converted into an angle value, i.e. the longitudinal value of the drill rod 11.
Step eight: obtaining the latitude D of the drill rod 11 according to the following formula (D) Lat (°):

Step nine: after the longitude and latitude of the drill rod 11 are obtained, a moving arrow is given on a screen of the machine intelligent terminal 8 to indicate a driver to drive the rotary drill to move, the system can continuously calculate the longitude and latitude of the drill rod 11, and the driver directly prompts driving according to the arrow until the drill rod moves to a target hole position to finish hole searching.
The positioning method of the invention is different from the prior art in that: in the prior art, calculation is performed by using plane geometry and other modes after the plane is approximated, the spherical factors of the earth are considered, the longitude and latitude of the drill rod 11 are directly obtained, the device and equipment for calculation and configuration are greatly simplified, and the equipment cost is reduced. In addition, the earth is approximately spherical (ellipsoid) in nature, but the hole searching distance of the drilling machine is about 50 meters at the maximum, and the distance of 50 meters is very small relative to the earth, so the method can be used for calculating in a spherical (circular) manner, and the error caused by the spherical shape of the earth can be completely ignored.
In addition, because the invention does not have the GPS antenna which is configured to measure the hole depth at the same time as other methods in the prior art, the invention uses the hole depth detection device 9 to detect the drilling depth in real time when in work, and uses the motor rotating speed of the drill rod motor 12 and the motor current for assisting the matching to judge whether the drilling hole is a slag hole or a water hole or whether the underground is a particularly hard rock mass, and the concrete steps are as follows:
step one, prepare the contrast data and input the board intelligent terminal 8, the contrast data includes:
firstly, collecting the average motor rotating speed S when the roller-bit drill drills in the last year are drilled Flat plate (RPM)；
(II) collecting the average motor current C when the cone drill drills in the last year Flat plate (A)；
(III) collecting the average drilling machine speed V when the cone drilling machine drills in the last year Flat plate (m/10min)；
Step two: when the roller-bit drilling machine works, acquiring the current real-time motor rotating speed S (RPM), the real-time motor current C (A) and the real-time drilling machine speed V (m/10 min);
step three: and comparing and judging the real-time data obtained in the step two and the comparison data obtained in the step one, specifically:
