Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coal mine underground drilling measurement, in particular to a continuous push rod pushing length automatic identification device and method based on a mine-used mobile phone. BACKGROUND

[0002] With the continuous deepening of coal mine exploration, the safety responsibility requirement of coal mine drilling safety operation is also higher and higher. In order to accurately and early find out safety hidden dangers, prevent responsibility accidents and false drilling phenomenon, the design, construction and acceptance requirements of coal mine drilling are also more and more strict. In order to ensure that the actual drilling track and drilling depth meet the design requirements, various instruments and equipment are introduced to detect the drilling and evaluate the quality, especially the drilling depth measuring instrument.

[0003] At present, most of the depth and track measurement and acceptance devices of the completed drilling hole in the coal mine underground market use push rods as the tools for pushing the track measuring instrument into the hole and sending it to the bottom of the hole. The working method is as follows: the track measuring instrument is connected to the front end of the push rod, the mine-used mobile phone and the measuring instrument are started synchronously (the time and working state of the mobile phone and the instrument are synchronous), the depth and time are manually input or recorded every time the push rod is pushed, and after the push rod is pushed to the bottom, the inclination and azimuth of the instrument at each hole depth recording point are read by using the hole device, so as to form the track data and curve.

[0004] The push rod is divided into meter joint push rod and continuous push rod. The meter joint push rod is composed of carbon fiber pipes with a unit length of 1 meter, and the instrument is pushed to the bottom of the hole by continuously connecting the meter joint push rod. Since the push and pull process needs to be continuously connected and disconnected, it will lead to long measurement time and large workload, so the meter joint push rod has been gradually replaced by the continuous push rod.

[0005] The continuous push rod can realize continuous pushing because there is no intermediate connection link. There are two methods for recording the pushing length of the continuous push rod at present, one is mechanical encoder, and the other is photoelectric encoder. The mechanical encoder needs a complex transmission mechanism and can only be read manually, and cannot be automatically obtained. The photoelectric encoder needs to increase electrical equipment on the continuous push rod, and the structure is complex. The electrical equipment has strict requirements in the coal mine underground, and the cost is very high. At the same time, in order to ensure the accuracy of the identification of the pushing length, the installation position and the orthogonal error have clear requirements. SUMMARY

[0047] Embodiment two

[0048] The continuous push rod pushing length automatic identification method based on the mine mobile phone provided in the embodiment is applied to the continuous push rod pushing length automatic identification device based on the mine mobile phone provided in the embodiment one, and includes the following steps.

[0049] Step 1: the continuous push rod is hoisted on the continuous push rod frame through the lifting eye screw, and the continuous push rod is pressed into the U-shaped groove of the U-shaped wheel through the pressing mechanism and the friction roller;

[0050] Specifically, the magnetic rotating wheel matching the specifications and the measurement accuracy of the continuous push rod is selected in advance, the radius (denoted as R) of the friction roller and the magnetic group number (denoted as N) of the permanent magnet are determined, then the magnetic rotating wheel is fixed on the fixed plate of the continuous push rod frame through the fixed assembly, and the mine mobile phone is fixed on the mobile phone support of the continuous push rod frame.

[0051] Step 2: the continuous push rod is placed at the hole opening, and the initial hole depth is input on the mine mobile phone;

[0052] Specifically, the continuous push rod is pushed through the friction roller, placed at the orifice, and the initial hole depth (denoted as L0) is input on the mining mobile phone.

[0053] Step 3: Push the continuous push rod, which drives the friction roller to rotate, and in turn drives the magnetic runner to rotate.

[0054] Step 4: The mining mobile phone detects the magnetic field strength change data of the magnetic runner through the internal three-axis magnetic sensor and transmits it to the processor inside the mining mobile phone. The processor first filters the magnetic field strength change data using a digital bandpass filtering algorithm to obtain an alternating current signal, then extracts and identifies the pulse signal and rotation direction at each moment from the alternating current signal using a wavelet Fourier algorithm, and finally accumulates all the pulse signals and rotation directions at each moment to obtain the final push length of the continuous push rod.

[0055] Specifically, the three-axis magnetic sensor inside the mining mobile phone detects the magnetic field strength change of the magnetic runner. According to the principle of electromagnetic field, when the magnetic runner rotates, it will generate a magnetic field in space with constant size and rotate at a certain speed. According to the Biot-Savart law, the magnetic field influence of the magnetic runner on a certain point in space is related to the direction and distance. Since the installation position of the mining mobile phone and the magnetic runner is relatively fixed, the magnetic field strength detected by the three-axis magnetic sensor inside the mining mobile phone is directly related to the rotation speed and angle of the magnetic runner and the distance from the three-axis magnetic sensor. Therefore, when the magnetic runner rotates at a certain angular velocity (denoted as ω), it will generate an alternating magnetic signal. Similarly, the three-axis magnetic sensor inside the mining mobile phone will also generate an alternating magnetic signal, i.e.

[0056] MT(t) = MT0 + MA*Sin(ω / N*t + ω0)

[0057] where MT0 represents the initial magnetic field strength value, MA represents the magnetic field strength amplitude, ω0 represents the phase shift, MA = μ0*(3(m*r)*r-m) / (4π*r 3 ), where μ0 represents the vacuum permeability (constant value), m represents the magnetic dipole moment of the permanent magnet (m is a constant value related to material, volume and magnetization), and r represents the distance between the magnetic sensor and the permanent magnet.

[0058] In this embodiment, when the rotation direction of the magnetic runner changes, the direction of the magnetic force line passing through the three-axis magnetic sensor inside the mining mobile phone also changes, so the phase, amplitude of the three-axis magnetic sensor inside the mining mobile phone can be used to determine the rotation direction of the magnetic runner.

[0059] After obtaining the magnetic field intensity variation data (i.e. alternating magnetic signal), the processor inside the mine-used mobile phone filters the alternating magnetic signal (MT(t)) by using a digital band-pass filtering algorithm, so as to obtain a set of AC signals without DC component MA(t)=MA*Sin(ω / N*t+ω0), and then uses a wavelet Fourier algorithm to extract and identify the pulse signal and its rotation direction at a certain time, i.e.

[0060] Vp(t)=(-1) p icw

[0061] wherein, p icw represents the rotation direction, when rotating clockwise, p icw =2, and when rotating counterclockwise, p icw =1. In the embodiment, it is assumed that the clockwise rotation represents the increase of hole depth, according to the structure of the magnetic wheel, one pulse signal represents that the magnetic wheel has rotated by an angle of one magnetic group, and the corresponding pushing length value is dL=2πR / N.

[0062] Finally, the pulse number and rotation direction are accumulated to obtain the final pushing length of the continuous push rod, i.e.

[0063] DL=L0+∑dL*Vp(t)

[0064] wherein, DL represents the final pushing length of the continuous push rod, L0 represents the initial hole depth, dL represents the pushing length change value corresponding to a single pulse, Vp(t) represents the pulse direction at time t, and ∑ represents the accumulation sum of the hole depth changes of all pulses.

[0065] The specific implementation of each structure in the continuous push rod pushing length automatic identification method based on the mine-used mobile phone can be referred to the limitation of the continuous push rod pushing length automatic identification device based on the mine-used mobile phone in the above description, and will not be described here.

[0066] The technical features of the above embodiments can be combined in any manner (as long as the combination of the technical features does not exist contradiction), in order to make the description simple, not all possible combinations of the technical features in the above embodiments are described; these embodiments which are not explicitly written should also be considered as the scope of the present disclosure.
