Detailed description of the invention
A kind of colliery gyro ceremony drilling rod localization method, comprises the following steps:
The demarcation of benchmark
Horizontal level and laneway midline are two benchmark (inclination angle and azimuthal dead-center position) measured, and need to carry out horizontal plane and the demarcation of center line direction to sensor in measuring process.
1, laneway midline alignment
Sensor is installed a lasing area light source, this surface of light source and instrument shaft line parallel, area source is projected in top, tunnel and forms straight line, adjustment sensor makes this straight line overlap with top, tunnel center line (or two center line reference points), now sensor axis overlaps at horizontal plane inner projection in theory with center line, using the dead-center position of this position of sensor as the azimuthal measurement of drilling rod.
2, sensor levels adjustment
Sensor is placed on the horizontal stand being adjusted to level in advance, keeps now 3-axis acceleration data, using the foundation that now acceleration information is demarcated as horizontal plane when measuring.
When measuring, sensor being put on adjustable support, regulating support, making the 3-axis acceleration data of sensor identical with the horizontal brief acceleration data of preserving before this, can be considered the level of sensor maintenance this moment.Using the dead-center position of this position of sensor as drilling rod measurement of dip angle.
3, zero point, state was demarcated
After the adjustment of above two steps, can sensor Ref be demarcated zero point, demarcate (preserve zero point state) now state as the zero point of drilling rod inclination angle and azimuth determination.
Azimuth and inclination angle export
After completing sensor Ref demarcation, random movable sensor, acceleration transducer on sensor and gyroscope survey data will change in real time, using 3-axis acceleration data and three axis angular rate data as original input data, carry out filtering, attitude algorithm, error concealment, the inclination angle of last output transducer in real time and azimuth, and display is on a sensor.Be fixed on drilling rod by this instrument, and keep axis parallel with drill rod axis, sensor will export azimuth and the inclination angle of drilling rod in real time, after sensor has once been demarcated, can take multiple measurements before being powered off to the multiple bore positions under same tunnel.
Fixing of sensor
Only use 3-axis acceleration data and three axle magnetometer data as input in step B, direct output transducer inclination angle and azimuth, owing to not using magnetometer data, magnetic field on sensor without impact, and because drilling rod is cylindric, and the drilling rod size of various rig is identical with each portion of model, being fixed on of sensor is made drilling rod also to keep parallel with drill rod axis more difficult, in most of rig, there is the guide pass that two parallel with drilling rod, lead for drilling rod feeding, can by sensor magnet adsorption on guide level, and keep sensor axis with outside guide rail along parallel, so the data that go out of sensor measurement are just in time equal with azimuth with the inclination angle of drilling rod.This fixing means is simple and convenient, and does not affect certainty of measurement.
The three-axis gyroscope that the gyroscope that the present invention uses is Invensense, LASER Light Source is level gauge laser module.
In prior art, measuring method has two kinds: bevel protractor is measured and electronic compass is measured.
Bevel protractor measure adopt the instrument such as protractor, cotton rope to measure more, this measuring method due to accuracy of measurement tool low, measuring process manually participates in too much, causing precision very low, same drilling rod, needs repetitive measurement to average to reduce error, bothersome effort.Traditional measurement once probably needs about 15 minutes.
Electronic compass is measured, and existing electronic compass is divided into two kinds, and one adopts fibre optic gyroscope to measure, and the method instrument precision is high, and error is 0.5 degree/360 degree.But price is very expensive, price is not at more than 10 ten thousand yuan to 200,000 yuan etc.Gyroscope+acceleration that another kind of employing is traditional, assisting magnetic meter is calibrated.The maximum shortcoming of the method is that survey data is very responsive to magnetic field (Hard Magnetic and soft magnetism), as long as sensor proximity has Hard Magnetic or soft magnetic materials, greatly will affect certainty of measurement.Certainty of measurement is at 3 degree ~ 4 degree/360 degree.These two kinds of measuring method single measurement time about 2-3 minute.
The above two kinds of measuring methods of contrast: this method adopts the scheme of gyroscope+acceleration, concentrate the advantage of existing electronic compass product, both avoided the impact of magnetic field on sensor accuracy class, and made again cost greatly reduce, precision is at 0.5 degree/360 degree ~ 1.0 degree/360 degree.Too much preparation is not needed, without the need to taking multiple measurements same drilling rod in measuring process.Repetitive measurement has very high repeatability.This method single measurement time about 2-3 minute.
Precision: error that the program is surveyed and measurement relative angle are directly proportional, and as sensor rotation 360 degree, error is 1 degree, so rotates 180 degree, error is at about 0.5 degree, and error and the relative angle turned present linear relationship roughly.
Concrete correction data refers to following table:
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
