And arranging a third straight line at a position 10 meters away from the second target position on an extension line of a connecting line between the ground positions corresponding to the two latest target positions, wherein the third straight line is perpendicular to the extension line of the connecting line. A plurality of third sample points are disposed on the third straight line.
In one embodiment, the processor may determine an average of the peak amplitudes for each target location, and take the average of the peak amplitudes for each target location as the buried depth of the optical cable corresponding to each target location.
In an embodiment, there is provided a processor configured to perform a method for determining a cable run according to any of the above.
A circulator in the positioning device of the optical cable coiling cable can be connected with the buried optical cable, obtains a vibration signal of the buried optical cable, and determines a corresponding waveform according to the received vibration signal. A plurality of sampling points can be arranged on the ground above the buried optical cable, and each sampling point can be knocked, so that the processor obtains the vibration signal of the buried optical cable at each sampling point. Since there may be other interfering vibration signals, it is necessary to acquire the waveform of the vibration signal again when the frequency of the vibration signal matches the preset frequency. The preset frequency of the vibration signal may be set to coincide with the frequency of tapping the sampling point.
The operating personnel can set up a plurality of first sampling points with positioner access buried optical cable in waiting to detect the region, and for the vibration signal of more obvious acquisition first sampling point, operating personnel can wait to detect the subaerial iron plate of placing of region, strikes the iron plate of first sampling point top to obtain the first vibration signal that first sampling point corresponds and the wave form of first vibration signal.
The processor may set the first preset frequency to tap each first sampling point, for example, the processor may set the first preset frequency to 1 second at an interval, tap once per second, and tap 5 times in total, and in order to distinguish other interfering vibration signals, the processor may set the preset frequency of the vibration signal to 1 tap feature appearing every second, and five times in total, so that when the frequency of the vibration signal acquired by the processor conforms to the preset frequency, it is determined that the acquired vibration signal is a valid vibration signal, thereby acquiring the waveform of the vibration signal. After the waveform of the vibration signal at the first sampling point is acquired, the processor may analyze the acquired waveform of the vibration signal. In a case where the waveform of the first vibration signal includes a preset waveform, the processor may determine a position corresponding to a central peak of the preset waveform as the predicted initial position. Wherein the preset waveform may be a waveform corresponding to the optical cable.
After determining the predicted initial position of the optical cable, the processor may determine the optical cable position of the positioning device and the predicted initial position of the optical cable, and determine the optical cable mileage at the predicted initial position of the optical cable, where the optical cable mileage is the optical cable distance between the optical cable position of the positioning device and the predicted initial position of the optical cable. After the processor determines the cable mileage at the predicted initial position, the cable mileage at the predicted initial position may be determined as the cable mileage at the starting point of the run of the cable to be confirmed.
For example, assuming that the processor sequentially acquires the first vibration signals of the first sampling points and determines the waveforms of the first vibration signals of the first sampling points, the frequency of the acquired first vibration signals is determined to conform to the preset frequency set by the processor, and the waveforms of the first vibration signals include the preset waveforms, as shown in fig. 3, the waveforms shown in fig. 3 are assumed to be the waveforms of the first vibration signals of the first sampling points. When the processor determines that the waveform of the first vibration signal includes the preset waveform a as shown in fig. 3, the processor may determine the optical cable position corresponding to more than one central peak of the preset waveform a, and determine the optical cable position corresponding to the central peak of the preset waveform a as the preset initial position. Meanwhile, assuming that the original point is the optical cable position where the positioning device is located, the processor may determine the optical cable mileage M between the position of the optical cable corresponding to the preset initial position and the optical cable position where the positioning device is located. The processor may determine the optical cable mileage M as an optical cable mileage M at the starting point of the optical cable to be determined, and the processor may determine the optical cable mileage as an optical cable mileage at the starting point of the optical cable to be determined, for example, assuming that the optical cable mileage at the initial position is predicted to be 500 meters at this time, the optical cable mileage at the starting point of the optical cable to be determined is 500 meters.
After the processor determines the predicted initial position of the optical cable according to the vibration signal of the first sampling point, a connection line between the ground position corresponding to the predicted initial position of the optical cable and the ground position corresponding to the positioning device can be determined. And determining a first straight line perpendicular to the connecting line at the ground position corresponding to the predicted initial position, and determining a plurality of second sampling points on the determined first straight line.
After the processor determines a plurality of second sampling points on the first straight line, an operator can knock each second sampling point according to a second preset frequency in sequence, the processor can receive vibration signals of the sampling points, and when the vibration signals acquired by the processor are consistent with the second preset frequency, the processor can determine that the vibration signals are the second vibration signals of the second sampling points. For example, the processor may set the second preset frequency to be once every three seconds, tapping the ground 3 times. After the processor acquires the second vibration signal of each second sampling point, the waveform of the second vibration signal can be acquired, and the average value of the peak amplitude of the waveform of each second sampling point is acquired. For example, assume that the processor sets the second preset frequency to be once every three seconds, tapping the ground 3 times. The processor may determine an average of peak amplitudes of waveforms of vibration signals obtained from three taps of the ground. The processor may determine an average of peak amplitudes of the waveform of the vibration signal at each second sampling point. And determining the waveform with the highest average value of the peak amplitudes in the waveforms of the vibration signals of all the second sampling points, and determining the position corresponding to the central peak of the waveform with the highest average value of the determined peak amplitudes as the target position of the optical cable. That is, the position corresponding to the central peak of the waveform with the highest average value of the peak amplitude is the buried position of the optical cable.
After the processor determines the target position of the optical cable by acquiring the waveform of the vibration signal of the second sampling point, the processor can determine the ground position corresponding to the target position of the optical cable, determine the ground distance between the ground position corresponding to the target position of the optical cable and the ground position corresponding to the position of the positioning device, and judge whether the ground distance is smaller than a preset threshold value set by the processor. The preset threshold set by the processor may be determined according to the range of the optical cable to be determined to be routed, which is determined by the operator. When the processor determines that the ground distance between the ground positions corresponding to the positions of the positioning devices is smaller than the preset threshold value set by the processor, the processor may determine a connection line between the ground position corresponding to the target position and the ground position corresponding to the positioning devices, and determine a plurality of third sampling points on a second straight line perpendicular to an extension line of the connection line. The processor may set a preset distance, and determine a position at the preset distance from the target position on an extension line of a connection line between the ground position corresponding to the target position and the ground position corresponding to the positioning device, so that the second straight line passes through the position at the preset distance from the target position. For example, assuming that the processor sets the preset distance to 10 meters, on an extension line of a connecting line between the ground position corresponding to the target position and the ground position corresponding to the position of the positioning device, a second straight line is set at a position 10 meters away from the target position, and the second straight line is perpendicular to the extension line of the connecting line. A plurality of third sampling points are arranged on the second straight line.
After the processor determines a plurality of third sampling points on the second straight line, each third sampling point can be sequentially tapped according to a second preset frequency, so that a third vibration signal of each third sampling point is obtained. For example, the processor may set the second preset frequency to be once every three seconds, tapping the ground 3 times. After the processor acquires the third vibration signal of each third sampling point, the processor may acquire a waveform of the third vibration signal of each third sampling point, and acquire an average value of peak amplitudes of the waveform of each third sampling point. For example, assume that the processor sets the second preset frequency to be once every three seconds, tapping the ground 3 times. The processor may determine an average of peak amplitudes of waveforms of the third vibration signal obtained by triple-tapping the ground. The processor may determine an average of peak amplitudes of the waveform of the third vibration signal for each third sampling point. And determining the waveform with the highest average value of the peak amplitudes in the waveforms of the vibration signals of all the third sampling points, and determining the position corresponding to the central peak of the waveform with the highest average value of the determined peak amplitudes as the new target position of the optical cable.
For example, as shown in fig. 4, the optical cable is buried in soil, in order to determine a specific position of the optical cable in the soil, after the processor determines a target position of the optical cable through the second sampling points, a third straight line can be determined according to the target position and a ground distance of the positioning device, a plurality of third sampling points are arranged on the ground, the third sampling points can be arranged at a distance of 2 meters, the ground can be knocked by a knocking device for each third sampling point, so that a third vibration signal of each third sampling point is determined, and the processor can set a knocking frequency of the knocking device to be once every three seconds and knock the ground 3 times. After the processor acquires the third vibration signal of each third sampling point, the processor may acquire a waveform of the third vibration signal of each third sampling point, and acquire an average value of peak amplitudes of the waveform of each third sampling point. The processor may determine a waveform with a highest average value of peak amplitudes in waveforms of the third sampling point as a target waveform, and determine a position corresponding to a central peak of the target waveform as a new target position of the optical cable. I.e., the buried location of the cable. As shown in fig. 4, the position corresponding to the central peak of the target waveform is the position of the optical cable buried in the soil.
In one embodiment, as shown in fig. 5, after determining the target waveform and the position of the optical cable in the soil by the method shown in fig. 4, the processor may identify the waveforms of the sampling points, and as shown in fig. 5, in the case that the distance between the third sampling points is the same, but the waveform on the left side of the target waveform is significantly lower than the waveform on the right side, the processor may determine that facilities such as an oil and gas pipeline exist on the left side of the optical cable, which affect the density of the soil, so as to obtain the waveform of the third sampling point lower than the third sampling point without facilities in the ground on the right side.
After the processor determines a new target position of the optical cable, the processor may determine a ground distance between the ground position corresponding to the new target position and the ground position corresponding to the position of the positioning device according to the new target position, and determine whether the ground distance between the ground position corresponding to the target position and the ground position corresponding to the position of the positioning device is smaller than a preset threshold set by the processor, and under the condition that the ground distance between the ground position corresponding to the new target position and the ground position corresponding to the position of the positioning device is smaller than the preset threshold, the processor may determine a connection line of the ground positions of the two latest target positions, and determine a plurality of third sampling points on a third straight line perpendicular to the connection line. The processor may set a preset distance, and determine a position at the preset distance from the new target position on an extension line of the ground position corresponding to the two latest target positions, so that the third straight line passes through the position at the preset distance from the new target position. For example, assuming the processor sets the preset distance to 10 meters, the two latest target positions are the first target position and the second target position, respectively, where the first target position is earlier than the second target position. And arranging a third straight line at a position 10 meters away from the second target position on an extension line of a connecting line between the ground positions corresponding to the two latest target positions, wherein the third straight line is perpendicular to the extension line of the connecting line. A plurality of third sample points are provided on the third straight line.
The processor can determine a new target position of the optical cable again according to the waveform of the vibration signal of the determined plurality of third sampling points, determine whether the ground distance between the ground position corresponding to the new target position of the optical cable and the ground position corresponding to the position of the positioning device is smaller than a preset threshold value set by the processor, if the ground distance between the ground position corresponding to the new target position of the optical cable and the ground position corresponding to the position of the positioning device is smaller than the preset threshold value set by the processor, determine a third straight line perpendicular to the line extension line again according to the line connecting the ground positions of the two latest target positions, and determine a plurality of third sampling points according to the third straight line. Until the ground distance between the ground position corresponding to the determined new target position of the optical cable and the ground position corresponding to the position of the positioning device is greater than or equal to the preset threshold value set by the processor. At which point the processor may stop determining the third line and the third sample point.
The processor may determine connections between all of the target locations based on all of the determined target locations and determine the run of the optical cable based on the obtained connections between all of the target locations. The processor may also determine an average of the peak amplitudes for each target location, and use the average of the peak amplitudes for each target location as the buried depth of the optical cable corresponding to each target location.
