Description

Technical Field

[0001] This invention relates to the field of inclinometer technology, and in particular to an intelligent inclinometer device and method with dual detection of depth information at measuring points. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] Intelligent inclinometers are primarily used to replace manual measurement of the deformation of inclinometer tubes. Existing intelligent inclinometers mainly rely on the cable encoder of an electric winding module to determine the depth information at the measurement point, converting the encoder's rotation count into corresponding depth information. However, the inventors observed that in actual operation, relying solely on the cable encoder of the electric winding module to calculate the inclinometer's depth within the inclinometer tube can lead to calculation errors in certain situations. These errors mainly occur in moving parts such as the encoder, the electric winding module's drive shaft, support bearings, and couplings, which can randomly slip during movement, resulting in inaccurate depth measurements. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes an intelligent inclinometer device and method with dual detection of depth information at measuring points, thereby improving the accuracy of depth measurement using an inclinometer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: Firstly, an intelligent inclinometer with dual detection of depth information at measuring points is proposed, comprising: a cable laying device, a cable, a data acquisition unit, an inclinometer, and a control unit; the inclinometer is connected to the cable; multiple tags are set along the axial direction on the cable; The cable-laying device is used to control the movement of the inclinometer by adjusting the cable length; The data acquisition unit is used to acquire the position information of the cable during the movement of the inclinometer and to detect the tags on the cable. The control unit is used to determine whether the number of tags detected by the data acquisition unit is accurate based on the cable position information during the movement of the inclinometer. If accurate, the number of tags detected by the data acquisition unit is taken as the number of tags passed by the inclinometer during its movement. If inaccurate, the number of tags passed by the inclinometer during its movement is calculated based on the cable position information. Based on the number of tags passed by the inclinometer during its movement and the cable position information when the first tag is detected, the measurement depth of the inclinometer tube is calculated.

[0006] Furthermore, the control unit is used to subtract 1 from the number of tags passed by the inclinometer during its movement and then multiply by the actual distance between adjacent tags to calculate and determine the movement distance from the first detected tag to the inclinometer when it reaches the set position; based on the movement distance and the cable position information when the first tag is detected, the measurement depth of the inclinometer tube is obtained.

[0007] Furthermore, the control unit is used to calculate and determine the number of tags between two adjacent tags detected by the data acquisition unit based on the cable position information when the information is inaccurate; based on this number of tags and the number of tags detected by the data acquisition unit, the number of tags passed by the inclinometer during its movement is determined.

[0008] Furthermore, the control unit is used to calculate the distance between two adjacent tags detected by the data acquisition unit based on the cable position information; when the distance is not equal to the actual spacing between adjacent tags, it is determined that the number of tags detected by the data acquisition unit during the movement of the inclinometer is inaccurate.

[0009] Furthermore, the data acquisition unit includes a cable encoder and a tag detection module; The cable encoder is connected to the cable feeding device to obtain the cable's position information; The label detection module is connected to the inclinometer body via a detection bracket and is used to detect labels on cables; The line-laying device is fixed to the body of the inclinometer.

[0010] Furthermore, the testing stent includes a first stent, a second stent, and a third stent; The first bracket is connected to the inclinometer body; the second bracket is connected to the first bracket; the label detection module is fixed on the second bracket; the third bracket is connected to the second bracket, and the cable passes between the third bracket and the label detection module.

[0011] Furthermore, a roller is installed on the second bracket, located between the label detection module and the third bracket, and the cable passes through the space between the roller and the third bracket.

[0012] Furthermore, multiple first tags and multiple second tags are set on the cable, with the first tags and second tags being set alternately at intervals.

[0013] Furthermore, the cable feeding device uses an electric winding machine; the cable is wound onto the electric winding machine.

[0014] Secondly, a depth measurement method for an intelligent inclinometer device with dual detection of depth information at measuring points, as proposed in the first aspect, is presented, including: The movement of the inclinometer is controlled by adjusting the cable length through the cable-laying device; During the movement of the inclinometer, the data acquisition unit obtains the position information of the cable and detects the tags on the cable; The control unit determines whether the number of tags detected by the data acquisition unit is accurate based on the cable position information. If accurate, the number of tags detected by the data acquisition unit is taken as the number of tags passed by the inclinometer during its movement. If inaccurate, the control unit calculates and determines the number of tags passed by the inclinometer during its movement based on the cable position information. Based on the number of tags passed by the inclinometer during its movement and the cable position information when the first tag is detected, the control unit calculates and determines the measurement depth of the inclinometer tube.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention proposes an intelligent inclinometer device and method with dual detection of depth information at measuring points. The device sets multiple tags on a cable and includes a data acquisition unit to acquire the cable's position information during the movement of the inclinometer and detect the tags on the cable. A control unit determines the number of tags passed by the inclinometer during its movement based on the cable's position information and the number of tags detected by the data acquisition unit. Then, based on the number of tags passed by the inclinometer during its movement and the cable's position information when the first tag was detected, the measurement depth of the inclinometer tube is calculated and determined. This eliminates calculation errors caused by cable slippage during movement, or accumulated calculation errors, thereby improving the accuracy of inclinometer depth measurement.

[0025] Where there is no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0026] First, the application scenarios of an intelligent inclinometer device with dual detection of depth information at measuring points, as proposed in the embodiments of the present invention, will be described.

[0027] The present invention proposes an intelligent inclinometer device with dual detection of depth information at measuring points, which is applied to the specific application scenario of depth measurement of an inclinometer.

[0028] With rapid economic and social development, numerous artificially excavated slopes have been constructed in fields such as water conservancy, transportation, and construction. Combined with naturally formed slopes, slope stability is a significant concern, making slope deformation and failure a common natural disaster. Slope instability can range from affecting project quality and construction progress to causing casualties and substantial economic losses. Therefore, slope stability is a crucial consideration in both natural disaster prevention and control and civil engineering and water conservancy projects.

[0029] Inclinometer tubes are aluminum alloy or high-strength plastic pipes installed within a landslide body, traversing the sliding surface. They possess good hardness and ductility, and their deformation can indirectly reflect the landslide's movement. Intelligent inclinometer devices are primarily used to replace manual measurement of inclinometer tube deformation. These devices mainly include an electrical control box, an electric winding module, an electric tilting module, an inclinometer, cables, and a storage tube. The current measurement method involves first lowering the inclinometer tube to the bottom using the electric winding module, then taking measurements every 0.5 meters until reaching the tube opening. Due to the high accuracy requirements, to eliminate systematic errors in the inclinometer, the electric tilting module rotates the inclinometer 180 degrees before lowering it back to the bottom, repeating the measurement. The two results are then added together and divided by two to obtain the final measurement.

[0030] In existing intelligent inclinometer devices, the depth information of the measuring point is mainly determined by the cable encoder of the electric winding module, which converts the number of rotations of the encoder into the corresponding depth information of the measuring point.

[0031] Cable encoders are used to monitor the distance a cable travels. For example, when a slewing cable is raised or lowered, it pulls the bearing connected to the encoder to rotate. If the cable descends a certain distance, causing the bearing to rotate two revolutions, then this distance is equal to the product of two revolutions and the bearing's circumference, from which the cable's displacement can be calculated. In actual operation, slippage may occur between the cable and the bearing under special circumstances. For example, it may rotate only 1.8 revolutions instead of the expected two. In this case, the product of 0.2 revolutions and the circumference is the resulting error. For example, if the cable encoder bearing circumference is 10cm, and one revolution of the bearing generates 10,000 pulses, then the distance of one pulse is 10 / 10000cm, or 0.001cm. Before starting the device, this pulse is reset to zero. As the cable descends (forward rotation), the pulse increases; as the cable ascends (reverse rotation), the pulse decreases. When the pulse reading is 300,000, the distance traveled is 300,000 * 10 / 10,000, which is 300 cm. If the initial position is -0.7 m, the current probe position is -0.7 + 3 = 2.3 m. Slippage between the cable and the bearing can cause pulse loss. The reading should be 300,000, but due to slippage, 295,000 pulses are actually read (295,000 * 10 / 10,000). The device will then interpret this as the cable descending 2.95 meters, when in fact it descended 3 meters, resulting in a 0.05-meter error. This error cannot be eliminated during the current measurement and will persist throughout the measurement until the cable pulls the probe back to its initial starting point, at which point the pulse is reset to zero.

[0032] In actual operation, when the depth of the inclinometer in the inclinometer tube is calculated solely by the cable encoder of the electric winding module, random slippage may occur in the moving parts such as the encoder, the drive shaft of the electric winding module, the support bearing, and the coupling, resulting in a certain probability of calculation error.

[0033] The error can only be eliminated from the location where it occurs until the inclinometer moves to the pipe opening and the top position is recalibrated. Before the calibration operation, the error generated by the cable encoder will cause deviations between the inclinometer data measured later and the inclinometer data at the corresponding normal depth. In the subsequent cumulative displacement calculation process, these deviations are continuously accumulated, eventually causing the current measurement results to deviate significantly from historical data, thus requiring supplementary measurements to be performed again.

[0034] In addition, the inventors also discovered that in some situations, after long-term operation, the inclinometer cable would wear out, causing the labels on the cable to be damaged to varying degrees, making it impossible to detect.

[0035] It is evident that any single method for detecting the depth of a measuring point has certain limitations.

[0036] To achieve accurate measurement of the inclinometer depth and prevent cable wear, this invention proposes an intelligent inclinometer device with dual detection of measurement point depth information. The data acquisition unit acquires the cable position information during the inclinometer's movement and detects tags on the cable, obtaining the cable position information when the first tag is detected. When the control unit calculates and determines the measurement depth of the inclinometer tube, the number of tags detected by the data acquisition unit is corrected using the cable position information to obtain an accurate number of tags passed by the inclinometer during its movement. Then, based on this number of tags and the cable position information when the first tag is detected, the accurate determination of the inclinometer tube's measurement depth is achieved, eliminating measurement point depth errors and improving the accuracy of the inclinometer tube's depth measurement.

[0037] like Figures 1-7 As shown in the figure, an intelligent inclinometer with dual detection of depth information of measuring points proposed in this embodiment of the invention includes: a cable laying device, a cable 3, a data acquisition unit, an inclinometer 2, and a control unit 13; the inclinometer 2 is connected to the cable 3; multiple tags are set on the cable 3 along the axial direction; The cable-laying device is used to control the movement of the inclinometer by adjusting the cable length; The data acquisition unit is used to acquire the position information of the cable during the movement of the inclinometer, and to detect the tags on the cable to acquire the position information of the cable when the first tag is detected. The control unit is used to determine whether the number of tags detected by the data acquisition unit is accurate based on the cable position information during the movement of the inclinometer. If accurate, the number of tags detected by the data acquisition unit is taken as the number of tags passed by the inclinometer during its movement. If inaccurate, the number of tags passed by the inclinometer during its movement is calculated based on the cable position information. Based on the number of tags passed by the inclinometer during its movement and the cable position information when the first tag is detected, the measurement depth of the inclinometer tube is calculated.

[0038] In some embodiments, the control unit is configured to subtract 1 from the number of tags passed by the inclinometer during its movement and multiply the result by the actual distance between adjacent tags to calculate and determine the movement distance from the first detected tag to the inclinometer when it reaches the set position; and obtain the measurement depth of the inclinometer tube based on the movement distance and the cable position information when the first tag is detected.

[0039] The movement of the inclinometer 2 includes upward movement and downward movement. The upward movement refers to the movement of the inclinometer from the bottom of the inclinometer tube to the opening of the inclinometer tube, and the downward movement refers to the movement of the inclinometer from the opening of the inclinometer tube to the bottom of the inclinometer tube.

[0040] If the inclinometer moves upwards from the bottom of the inclinometer tube, then the measured depth of the inclinometer tube is the cable position information when the first tag is detected minus the distance traveled from the first detected tag to the inclinometer reaching the set position, i.e.: L = A1 - (n-1) d; In the formula, L is the measurement depth of the inclinometer tube, A1 is the cable position information when the first tag is detected, n is the number of tags passed by the inclinometer during its movement, and d is the actual distance between adjacent tags.

[0041] If the inclinometer moves downwards from the inclinometer tube opening, the measured depth of the inclinometer tube is the sum of the cable position information when the first tag is detected and the distance traveled from the first detected tag to the inclinometer reaching the set position. L = A1 + (n-1) d; In the formula, L is the measurement depth of the inclinometer tube, A1 is the cable position information when the first tag is detected, n is the number of tags passed by the inclinometer during its movement, and d is the actual distance between adjacent tags.

[0042] In some embodiments, the control unit is configured to calculate the distance between two adjacent tags detected by the data acquisition unit based on the cable position information; when the distance is not equal to the actual spacing between adjacent tags, it is determined that the number of tags detected by the data acquisition unit during the movement of the inclinometer is inaccurate.

[0043] The control unit, when inaccurate, calculates the number of tags between two adjacent tags detected by the data acquisition unit based on the cable's position information. Based on this tag count and the total number of tags detected by the data acquisition unit, it determines the number of tags passed by the inclinometer during its movement. Specifically: based on the cable's position information, it determines the distance between two adjacent tags detected by the data acquisition unit, divides this distance by the actual distance between the tags, calculates the number of tags between two adjacent tags detected by the data acquisition unit, and rounds this number to the nearest integer. For example, if the calculated number of tags is 12.07 or 11.97, it is rounded down to 12.

[0044] The data acquisition unit reads the pulse changes every 20ms and determines the position change of the cable during this period based on the pulse changes. The position change is equal to the number of pulses in the current 20ms multiplied by the distance of a single pulse.

[0045] In this embodiment of the invention, the current measurement depth is updated every 20 milliseconds based on the change in the number of pulses. Taking the descent motion of the inclinometer as an example: current measurement depth = previous measurement depth + number of pulses in the current 20ms * distance of a single pulse.

[0046] like Figure 3 As shown, during the descent of the inclinometer, when the data acquisition unit detects the first tag, it records the position information of that first tag, such as y meters (because the tag interval is set to a distance d (d is 0.5 meters), it is impossible for it to be detected at the very beginning, so the position of the first tag must be recorded) and set as Subsequently, for each detected tag, the inclinometer's measured depth is calculated according to the formula. Calculate, where, Let d be the number of tags passed by the inclinometer during its movement. For example, if the second tag is detected, the depth is y + (2-1) * d meters; the third tag is y + (3-1) * d meters; and so on. Since the tag positions cannot be shifted, the depth information corresponding to the current tag is considered accurate and will replace (calibrate) the current depth value. The data acquisition unit will still read pulse values ​​every 20 milliseconds and add them to the current depth value. Therefore, even if slippage occurs, the error is limited to between two tags; the slippage error will be eliminated once the next tag is detected.

[0047] If one or more consecutive tags are not detected This approach is not applicable because the value of n is unknown. Since the cable encoder in the data acquisition unit is still working normally, it will calculate n based on the depth. If the current depth determined by the cable encoder is 5.32 meters and the first tag is -0.3 meters, then n = (5.32 + 0.3) / 0.5 + 1 = 12.24, which is the twelfth tag. According to y + (n - 1) * 0.5, the current depth should be 5.2 meters, so the 5.32 meters will be calibrated to 5.2 meters, thus completing the depth calibration.

[0048] Furthermore, when the control unit detects the tag again, it automatically calculates the cable position information recorded by the cable encoder. The value is used to complete the depth calibration.

[0049] like Figure 4 As shown, during the ascent of the inclinometer, the same depth calibration procedure as during the descent must be performed to prevent the accumulation of errors. The depth measurement during this process is calculated using the formula... calculate.

[0050] In some embodiments, the cable feeding device is an electric winding machine; the cable is wound on the electric winding machine, and the electric winding machine winds the cable onto the winding machine by rotating forward and backward, controls the inclinometer to move upward, and releases the cable from the winding machine, controls the inclinometer to move downward.

[0051] like Figure 1 As shown, the control unit 13 and the wire laying device are mounted on the body 1 of the inclinometer.

[0052] In some embodiments, the data acquisition unit includes a cable encoder and a tag detection module 11; The cable encoder is connected to the cable feeding device to obtain the cable's position information; The label detection module 11 is connected to the inclinometer body 1 via the detection bracket 4 and is used to detect labels on the cable; The line-laying device is fixed on the body 1 of the inclinometer device.

[0053] The label detection module 11 can use a label detection sensor, such as an electromagnetic induction chip.

[0054] like Figures 5-6 As shown, the detection bracket 4 includes a first bracket 7, a second bracket 9, and a third bracket 10; The first bracket 7 is connected to the inclinometer body 1; the second bracket 9 is connected to the first bracket 7; the label detection module 11 is fixed on the second bracket 9; the third bracket 10 is connected to the second bracket 9, and the cable 3 passes through the third bracket 10 and the label detection module 11.

[0055] This enables the label detection module 11 to detect the labels on the cable.

[0056] In some embodiments, a roller is provided on the second bracket 9, the roller is located between the label detection module 11 and the third bracket 10, the cable 3 passes between the roller and the third bracket 10, and is able to move along the cable axis.

[0057] By setting rollers, friction between the cable and the label detection module 11 during operation is prevented, thereby extending the service life of the label detection module 11.

[0058] Preferably, the first bracket 7 is fixed to the body 1 of the inclinometer device by screws; the second bracket 9 is fixed to the first bracket 7 by screws; the roller includes a pin 12 and a roller 8; the pin 12 is fixed to the second bracket 9, and the roller 8 is loosely fitted on the pin 12 and can rotate freely around the axis of the pin 12. Preferably, the roller 8 is made of wear-resistant plastic to reduce the friction between the roller 8 and the cable 3 and improve its service life.

[0059] A set of pins 12 and rollers 8 are respectively provided above and below the label detection module 11 to protect the label detection module 11 and prevent the cable 3 from rubbing against the label detection module 11 during movement.

[0060] The third bracket 10 is fixed to the second bracket 9 by screws. Preferably, the third bracket 10 is made of wear-resistant plastic to reduce occasional friction between the cable 3 and the third bracket 10.

[0061] The sensing end of the tag detection module 11 faces the third bracket to detect the tags on the cable 3.

[0062] In some embodiments, a plurality of first tags 5 and a plurality of second tags 6 are provided on the cable 3, the first tags 5 and the second tags 6 being arranged alternately at intervals, each corresponding to a different depth, such as... Figure 2 As shown.

[0063] Preferably, the first label is made of copper foil and the second label is made of aluminum foil; or the first label is made of aluminum foil and the second label is made of copper foil.

[0064] The actual distance between two adjacent labels can be set according to requirements, such as 0.5 meters.

[0065] This invention proposes an intelligent inclinometer with dual detection of depth information at measuring points. Multiple tags are set on a cable, and a data acquisition unit acquires the cable's position information during the inclinometer's movement and detects the tags on the cable. A control unit determines the number of tags passed by the inclinometer during its movement based on the cable's position information and the number of tags detected by the data acquisition unit. Then, based on the number of tags passed by the inclinometer and the cable's position information when the first tag is detected, the measurement depth of the inclinometer is calculated. This eliminates calculation errors caused by cable slippage during movement, or accumulated calculation errors, thus improving the accuracy of inclinometer depth measurement.

Based on the number of tags passed by the inclinometer during its movement and the cable position information when the first tag is detected, the control unit calculates and determines the measurement depth of the inclinometer tube.
