Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The method for measuring the tunneling footage and the footage measurement base station according to the embodiment of the present application will be described below with reference to the drawings.
Fig. 1 is a flowchart of a method of measuring a tunneling footage according to an embodiment of the present application. It should be noted that the main implementation body of the method for measuring the roadway excavation footage provided in this embodiment is a footage measuring base station, where the footage measuring base station in this embodiment may be arranged on the excavation equipment.
It should be noted that the footage measuring method can be applied to a coal mine underground single-lane driving working face or a multi-lane driving working face (for example, a coal mine underground double-lane driving working face). Fig. 3 is a schematic working surface view of a tunneling footage according to an embodiment of the present application. It should be noted that fig. 3 illustrates a coal mine underground double-roadway tunneling working face as an example.
As shown in fig. 1, the method for measuring the tunneling footage includes:
In some embodiments, during double-lane tunneling operation in an underground coal mine, tunneling equipment needs to pass through a joint lane to perform alternate tunneling operation between two lanes. The heading equipment may be any of the roadways in which heading work is performed.
In some embodiments, a tag with an independent ID (Identity Document identification number) is installed at a reference position of a heading tunnel, the tag of the heading tunnel 1 is named as tag 1, the tag of the heading tunnel 2 is named as tag 2, the tag 1 and the tag 2 have different tag identifications, and a corresponding relationship between the tag identifications and the heading tunnel can be pre-stored in a footage measuring base station, so that the heading tunnel where the heading equipment is currently located can be determined based on the tag identifications. An exemplary diagram of setting a tag in a heading lane can be seen in fig. 3.
Specifically, a tag signal is detected at the footage measuring base station, a tag identification in the tag signal is read and recognized, a tunneling roadway represented by the tag identification is judged, and the tunneling roadway is used as a roadway where the tunneling equipment is located currently.
For example, referring to fig. 3, when the label identifier represents a tunneling roadway 1, the measurement base station determines that the tunneling roadway where the current tunneling equipment is located is the tunneling roadway 1; and when the label mark represents the tunneling roadway 2, the measurement base station confirms that the tunneling roadway where the current tunneling equipment is located is the tunneling roadway 2.
In some embodiments, when the footage measuring base station detects that the current time reaches the current time point needing to be acquired, the footage measuring base station starts to measure the distance between the footage measuring base station and the measurement tag, and the distance is used as the first distance L1.
Specifically, the footage measuring base station measures the distance value between the footage measuring base station and the measuring label in real time, filters the distance interference value through a filtering algorithm and takes the average value in a period of time as the real-time data of L1.
It should be noted that, during the tunneling process, the footage measuring base station will periodically detect the tag signal and automatically measure the distance to the measuring tag. And if the measuring base station cannot detect the measuring label and exceeds a certain time, the alarm module of the measuring base station starts acousto-optic alarm display and sends error information to the tunneling equipment through communication or uploads the error information through the underground looped network. If the measuring base station can detect the signal of the measuring tag, the real-time measurement is maintained and the L1 at this time is recorded.
In some embodiments, the footage measurement base station automatically acquires the first position in real time, and simultaneously acquires the reference footage data L0 corresponding to the measurement tag at the first position.
It should be noted that the reference footage data L0 at this time is an initial reference footage, and is previously entered into the footage measurement base station by the downhole worker through the touch display screen of the footage measurement base station.
In addition, after the position of the measurement tag in the current roadway is updated, the downhole worker can manually calibrate the reference footage according to the new position of the measurement tag in the current roadway, and automatically update and record the reference footage data L0 corresponding to the new position of the measurement tag in the current roadway.
And 104, acquiring a second distance L2 between the footage measuring base station and the tunneling section of the tunneling device.
In some embodiments, the measuring base station is mounted on the tunneling device, the measuring base station is kept at a certain distance from the tunneling section, and a second distance L2 from the measuring base station to the tunneling section of the tunneling device can be stored in the measuring base station in advance. And when the current time reaches the current acquisition time point, automatically acquiring the distance between the footage measurement base station and the tunneling section of the tunneling device in real time, and taking the distance as a second distance L2.
And 105, determining the tunneling footage L corresponding to the current roadway at the current time point according to the first distance L1, the reference footage data L0 and the second distance L2.
In some embodiments, after the footage measuring base station acquires the first distance L1, the reference footage data L0 and the second distance L2 of the current roadway at the current time, the calculation program is started to calculate the corresponding tunneling footage L. Specifically, the calculated value of the excavation depth L is the sum of three values of the first distance L1, the reference depth data L0, and the second distance L2 at the current time, and the calculation formula is L1+ L0+ L2, that is, the value of the excavation depth L is calculated and stored in real time.
In the method for measuring the tunneling footage according to the embodiment of the application, in the tunneling process, when a tag signal is detected, a roadway where a measurement tag corresponding to the tag identifier is located is determined according to the tag identifier in the tag signal, the roadway where the measurement tag is located is used as a current roadway where tunneling equipment is located, when it is detected that the current time reaches a current acquisition time point, a first distance L1 between a footage measurement base station and the measurement tag is obtained, a first position of the measurement tag in the current roadway is obtained, reference footage data L0 corresponding to the first position of the measurement tag is obtained, a second distance L2 from the footage measurement base station to the tunneling section of the tunneling equipment is obtained, and the tunneling footage L corresponding to the current time point is determined according to the first distance L1, the reference footage data L0 and the second distance L2. Therefore, real-time automatic measurement of the tunneling footage L is realized, and the intelligent level of the measurement of the tunneling footage L is further promoted.
On the basis of the foregoing embodiments, in some embodiments, in order to obtain more accurate tunneling penetration depth L data, before determining the tunneling penetration depth L corresponding to the current roadway at the current time point according to the first distance L1, the reference penetration depth L0, and the second distance L2, the distance between the measurement base station and the measurement tag when the last time point corresponding to the current time point and the last time point corresponding to the current time point are obtained may also be obtained, and the distance is used as the third distance L3, and the first distance L1 is compared with the third distance L3, and whether to determine the tunneling penetration depth L corresponding to the current roadway at the current time point is determined according to the comparison result.
Specifically, when it is determined that the first distance L1 is greater than the third distance L3 according to the comparison result, it is described that the measuring base station follows the heading equipment to advance in the heading direction, and at this time, the heading depth L corresponding to the current roadway at the current time point may be determined according to the first distance L1, the reference depth data L0 and the second distance L2.
It should be noted that, the measuring base station and the measuring tag are both provided with a distance measuring module, and the distance measuring module includes an acceleration sensor. When the tunneling equipment performs tunneling operation, the measuring base station advances towards the tunneling direction along with the tunneling equipment, and the acceleration value of the measuring base station is obtained by an acceleration sensor of the measuring base station. At the same time, the acceleration value of the measuring tag is obtained by the acceleration sensor of the measuring tag itself. The acceleration values of the measuring base station and the measuring label can be measured in real time and automatically stored by the controller.
In some embodiments, the acceleration directions of the measuring base station and the measuring tag are opposite and equal; in other embodiments, the acceleration directions of the measuring base station and the measuring tag are the same and are not equal in magnitude.
Specifically, in order to obtain more accurate tunneling penetration L data, the magnitudes of the first distance L1 and the third distance L3 are compared, and it is determined whether the first distance L1 is greater than the third distance L3. As a possible result, if the first distance L1 is greater than the third distance L3, that is, the distance between the measuring base station and the measuring tag is increasing and the acceleration value of the measuring tag is greater than the set threshold value, it indicates that the heading equipment is in a heading state.
At this time, the step of determining the tunneling penetration depth L corresponding to the current roadway at the current time point according to the first distance L1, the reference penetration depth data L0 and the second distance L2 is performed.
The set threshold value for measuring the acceleration of the label is a critical value of an acceleration value preset by a worker in advance.
In some embodiments, another achievable result of comparing the magnitudes of the first distance L1 and the third distance L3 is that the first distance L1 is smaller than the third distance L3, and at this time, the measuring base station may determine the reason why the processing caused the first distance L1 to be smaller than the third distance L3 according to the acceleration value of the measuring base station and the acceleration value of the measuring tag.
Among them, the reason why the first distance L1 is smaller than the third distance L3 may be three cases that (i) a worker moves the measurement tag to the measurement base station; the equipment retreats, namely the direction of the detected self acceleration is opposite to the tunneling direction of the equipment and the L1 is reduced; and thirdly, the device moves to another lane, namely after the L1 is detected to be reduced and kept for a period of time, the ID (Identity Document identification number) of the measuring tag is changed, and the device is automatically judged to have moved to another lane. At the moment, the maximum tunneling footage is determined from the tunneling footages L corresponding to the current roadway at a plurality of historical time points, the maximum tunneling footage is stored, and the position of the equipment in the current roadway is measured and displayed in real time.
Specifically, when it is detected that the first distance L1 is smaller than the third distance L3, the third distance L3 at this time is the maximum value between the measurement base station and the measurement tag, and the maximum tunneling depth is the tunneling depth at the time when the distance between the measurement base station and the measurement tag is L3, that is, the value of the third distance L3 at this time is assigned to the first distance L1, and the formula L is substituted into L0+ L1+ L2 to calculate, that is, the maximum value of the tunneling depth L can be determined and stored in real time.
In some embodiments, before the last time point corresponding to the current time point is obtained, it may be further determined whether the first distance L1 exceeds a preset distance threshold.
The preset distance threshold is a distance critical value between the footage measuring base station and the measuring label, which is preset in the footage measuring base station. As an example, the preset distance threshold may be a critical value of the footage measuring base station and the measuring tag, which is previously recorded by the staff, and the preset distance threshold may be stored in the memory of the footage measuring base station.
Specifically, it is determined whether L1 exceeds a preset distance threshold, and as an achievable result, if the first distance L1 does not exceed the preset distance threshold, the step of obtaining the previous time point corresponding to the current time point is performed.
In some embodiments, as another achievable result, if the first distance L1 exceeds a preset distance threshold, detecting whether the measurement tag has moved to the measurement base station end; after the measuring tag is detected to move towards the measuring base station, acquiring a second position of the measuring tag in the current roadway; determining a distance difference between the first location and the second location; and obtaining a value obtained by adding the distance difference and the reference scale-in data, and taking the value as the reference scale-in data corresponding to the second position of the measuring label.
Specifically, if the first distance L1 exceeds a preset distance threshold, the alarm module of the measuring base station performs sound-light alarmAnd displaying to prompt the staff that the distance between the measurement label and the measurement base station is about to exceed the measurement range of the measurement label and the measurement base station, so that the footage measurement failure can be caused, and the staff is reminded to move the measurement label to the measurement base station in time. When the worker moves the measuring label to the measuring base station, the advancing measuring base station detects the acceleration value of the measuring label in real time, the advancing step number and the advancing direction of the worker are calculated according to the step number algorithm and the acceleration data change, and the advancing distance S1 of the worker is calculated. In addition, the distance S2 from the start position to the end position of the measuring label is calculated
When the measurement label is moved to a new position, the new position of the measurement label is the second position, the difference between the first position and the second position of the measurement label is S2, and a value obtained by adding the difference S2 and the original reference footage data is used as new reference footage data corresponding to the second position of the measurement label, namely L0 is new to L0 original + S2, and the reference footage data is updated and stored in real time.
In some embodiments, the footage measurement base station may store the footage data for each lane. Therefore, statistics can be conveniently carried out on the basis of the roadway footage data stored in the footage measuring base station, for example, statistics on the roadway footage data in the aspects of shift footage, day footage, month footage, year footage and the like can be carried out.
In some embodiments, in order to enable the ground remote monitoring center to obtain the roadway footage data in time, the footage measuring base station can be connected with the underground looped network in a wireless or wired mode, and transmits the data to the ground remote monitoring center in real time through a network, so that the remote supervision of the footage data is realized.
In order to make the technical solution more clearly understood by those skilled in the art, fig. 2 is a flowchart of a method for measuring a tunneling footage according to another embodiment of the present application. The individual steps are explained in detail below:
And step 207, judging whether the roadway where the measurement tag is located is a tunneling roadway 1 or a tunneling roadway 2.
And step 208, acquiring a distance L1 between the footage measuring base station and the measuring label.
In step 209, it is determined whether L1 exceeds a preset distance threshold. If yes, go to step 210; if not, go to step 212.
And step 210, judging whether the automatic calibration reference footage condition is met. If yes, go to step 211; if not, go to step 217.
And step 211, automatically calibrating the reference footage.
In step 213, it is determined whether the amount of change in the footage data is increasing or decreasing. If so, go to step 214; if so, step 215 is performed.
And step 214, calculating a footage by using a filtering algorithm.
At step 215, the device is backing off.
At step 216, the maximum footage is recorded and the real-time position of the device is measured.
And step 217, setting parameters for program operation, displaying information, communicating and uploading data to the subprogram.
