Description

Technical Field

[0001] This invention relates to the field of traveling wave detection technology, and in particular to a broadband synchronous detection system based on traveling wave dual-end positioning. Background Technology

[0002] Traveling wave dual-end positioning detection technology uses detection equipment at both ends of a cable line to detect the traveling wave generated when a line fault occurs, and then uses mathematical calculations to determine the location of the fault, thereby achieving the positioning function.

[0003] A search revealed that Chinese utility model patent application number CN202123096183.6 provides a two-in-one sensor for measuring power frequency and high frequency signals of high-voltage cables. This device "connects the two parts of the sensor tightly through a hinge opening and a quick-locking buckle, achieving rapid sensor installation. The sensor's inner ring diameter can be adjusted using a quick-fixing bracket to accommodate cables of different thicknesses, achieving rapid sensor fixation." However, it has the following shortcomings: First, the quick-locking buckle is prone to reduced locking effectiveness (e.g., rebound) or even failure due to thermal expansion and contraction in environments with large seasonal or diurnal temperature variations, thus reducing detection stability; second, although it can adapt to cables of different thicknesses, multiple quick-fixing brackets need to be adjusted separately, which is time-consuming and labor-intensive; third, the quick-fixing bracket can clamp the cable... The sensor is tight, but once clamped, its position cannot be adjusted. For traveling wave detection, the positioning accuracy decreases as the cable length increases. If the traveling wave detection device could move along the cable line as needed, it could get closer to the fault point, facilitating fault identification and subsequent repair. This sensor does not have this function. Fourth, the immobile sensor makes it difficult to adjust its position relative to the line, which is detrimental to verifying its measurement accuracy. Fifth, when used on overhead lines, the sensor located on the cable experiences significant wind resistance due to the swaying caused by wind. The lack of a damping mechanism exacerbates the cable swaying, hindering its positional stability. In addition, there are detection devices on the market that use photovoltaic power generation, but their power supply method is still singular, and the lack of a cleaning mechanism results in poor stability of the photovoltaic power supply. Summary of the Invention

[0004] The purpose of this invention is to provide a broadband synchronous detection system based on traveling wave dual-end positioning to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A broadband synchronous detection system based on traveling wave dual-end positioning includes detection devices. Detection devices are installed at both ends of a linear cable, and the two detection devices communicate wirelessly. Each detection device includes an upper latching seat, a lower latching seat, a locking element, and an electrical control system. The upper and lower latching seats are hinged together at their rear ends to open and close relative to the cable. After engagement, the upper and lower latching seats form a cylindrical structure to insert the cable. The virtual axis of the cylindrical structure is parallel to the virtual hinge axis of the upper latching seat. The locking element includes a bidirectional screw, a handwheel, a compression spring, and a plug. The lower latching seat is rotatably connected to a bidirectional screw... The rod, the bidirectional lead screw, is coaxially fixed with a handwheel and is parallel to the cylindrical structure. The handwheel is rigidly connected coaxially in the middle of the bidirectional lead screw. Each of the left and right parts of the bidirectional lead screw is threaded with a plug. The two plugs are slidably connected to the lower fastening seat. The upper fastening seat has insertion holes on the left and right sides. The two plugs can be inserted into and detached from the insertion holes respectively. A compression spring is inserted into each of the left and right parts of the bidirectional lead screw with a gap. The two ends of the compression spring abut against the handwheel and the plug respectively. Under the elastic repulsive force of the compression spring, the two plugs tend to move away from each other. The electrical control system performs broadband traveling wave synchronous detection on the cable.

[0007] Based on the above technical solution, the left and right parts of the upper snap-fit ​​seat and the left and right parts of the lower snap-fit ​​seat are respectively slidably connected to lifting seats. Each lifting seat is rigidly connected to the upper snap-fit ​​seat and the lower snap-fit ​​seat with a No. 2 compression spring. Each lifting seat is rotatably connected to a V-shaped roller. The axis of the V-shaped roller is spatially perpendicular to the axis of the cylindrical structure. Under the elastic repulsive force of the No. 2 compression spring, the lifting seats where the upper snap-fit ​​seat and the lower snap-fit ​​seat are located tend to move closer to each other in the vertical direction, so that the V-shaped roller can roll and rub against the outer wall of the cable. The detection device also includes an electric rotary drive mechanism, which is electrically connected to the electrical control system.

[0008] Based on the above technical solution, the electric rotary drive mechanism includes a dual-axis servo motor, a worm gear, an upper drive shaft, a worm wheel, a lower drive shaft, an upper slot, an upper limit slot, a lower slot, a lower limit slot, a connecting plate, a connecting pin, and a transmission mechanism. The upper snap-fit ​​seat has a dual-axis servo motor fixed to its upper part. The axial ends of the rotating shaft of the dual-axis servo motor are respectively rigidly connected to worm gears coaxially. The worm gears are rotatably connected to the upper snap-fit ​​seat. Vertical upper drive shafts are rotatably connected to the left and right sides of the upper snap-fit ​​seat. Worm wheels are coaxially fixed to the two upper drive shafts, and the two worm wheels mesh with the worm gears. Vertical lower drive shafts are rotatably connected to the left and right sides of the lower snap-fit ​​seat. When the upper and lower snap-fit ​​seats are engaged, the lower drive shafts and upper drive shafts are coaxially arranged. The bottom end has an upper slot, and upper limit slots extend through it on both sides. The upper slot extends through the upper drive shaft from front to back. The top end of the lower drive shaft has a vertical lower slot, and lower limit slots extend through it on both sides. The lower slot extends through the lower drive shaft from front to back. The upper and lower drive shafts are jointly mounted with a connecting plate. The upper and lower parts of the connecting plate are rigidly connected to each other with connecting pins on the left and right sides. The upper and lower parts of the connecting plate are respectively interlocked with the upper slot and the lower slot. The connecting pins on the upper and lower parts of the connecting plate are respectively interlocked with the upper limit slot and the lower limit slot. The connecting plate can swing back and forth and move up and down along the upper and lower slots. The connecting pins can rotate and move up and down within the upper limit slot and the lower limit slot. The upper and lower drive shafts are connected to each V-shaped roller through a transmission mechanism.

[0009] Based on the above technical solution, the transmission mechanism includes an upper adjusting groove, a lower adjusting groove, a bushing, a transmission rod, a driving bevel gear, and a driven bevel gear. The upper transmission shaft passes through the upper adjusting groove on both sides, and the lower transmission shaft passes through the lower adjusting groove on both sides. The upper and lower transmission shafts are axially slidably connected to bushings, and each bushing is axially rigidly connected to a transmission rod. The transmission rod is interlocked with the upper or lower adjusting groove and can move up and down along the upper and lower adjusting grooves. Each bushing is rotatably connected to a lifting seat. Each bushing is coaxially fixed with a driving bevel gear, and each V-shaped roller is coaxially fixed with a driven bevel gear. Each driving bevel gear meshes with each driven bevel gear.

[0010] Based on the above technical solution, the electrical control system includes a wideband open-type current transformer. The wideband open-type current transformer includes a front half, a rear half, a first pin, and a first tension spring. The front half and the rear half are respectively inserted into the upper and lower snap-fit ​​seats to form a complete ring. The front half and the rear half are respectively slidably connected to the first pin. The two first pins are rigidly connected to the front half and the rear half by a first tension spring. Under the elastic tension of the first tension spring, the two first pins tend to move closer to each other and can be inserted into the upper and lower snap-fit ​​seats respectively. The wideband open-type current transformer is electrically connected to the electrical control system.

[0011] Based on the above technical solution, the electronic control system further includes a support component, a support frame, a wind turbine, a guide vane, and a conductive slip ring. The upper and lower fastening seats are detachably mounted on the right side of the support component. The bottom of the support component is rotatably connected to a vertical support frame. The virtual axis of the support frame is vertically oriented. The wind turbine is fixed inside the support frame, and a guide vane is fixed at its rear. The guide vane is radially oriented relative to the virtual axis of the support frame. The wind turbine and the guide vane are aligned front to back. The support component is equipped with a conductive slip ring. The rotor of the conductive slip ring is rigidly connected to the support frame, and the stator is rigidly connected to the support component. The stator of the conductive slip ring is electrically connected to the power processing module and the battery of the electronic control system, and the rotor is electrically connected to the wind turbine.

[0012] Based on the above technical solution, the support component includes a support shell, a locking mechanism, a support ring, and an elastic element. The support shell is inserted into the cylindrical structure from left to right and is also inserted into the cylindrical structure from front to back through the locking mechanism. The support shell is rotatably connected to the support ring, and the virtual axis of rotation of the support ring is coaxial with the cylindrical structure. Elastic elements are respectively installed between the front and rear parts of the support ring and the support shell. The support frame is rotatably connected to the support ring. The conductive slip ring is installed with the support ring. Under the elastic force of the elastic element, the support ring has the tendency to drive the support frame back to vertically downward. The upper part of the support shell and the upper part of the support ring are respectively provided with openings for cables to pass through.

[0013] Based on the above technical solution, an arc-shaped photovoltaic panel is fitted and fixed to the outer circumferential wall of the upper fastening seat, and brushes are fixed to the front and rear parts of the support ring. The bristles of the brushes are in contact with the surface of the photovoltaic panel, and the photovoltaic panel is electrically connected to the power processing module and the battery of the power control system.

[0014] Based on the above technical solution, the locking mechanism includes a second pin and a second tension spring. The front and rear parts of the support housing are each slidably connected with a second pin. The two second pins are rigidly connected to the support housing together with a second tension spring. Under the elastic tension of the second tension spring, the two second pins tend to move closer to each other and can be inserted into the upper and lower fastening seats.

[0015] Based on the above technical solution, the electronic control system includes a GPS / BeiDou dual-mode timing module, an STM32 / ARM main control module, a wireless communication module, a high-speed wideband operational amplifier circuit, a traveling wave signal conditioning circuit, a high-speed ADC, and a power supply.

[0016] Compared with the prior art, the present invention has the following advantages: When the two plug tubes are far apart from each other to a certain extent, they can be plugged into the socket, which makes it convenient to install the detection device outside the cable. Due to the use of the first compression spring, the two plug tubes always tend to be plugged into the socket, which can prevent accidental disengagement caused by thermal expansion and contraction and improve detection stability.

[0017] Under the elastic repulsive force of the second compression spring, the two lifting seats tend to move closer to each other, which enables the V-shaped roller to clamp the cable, thus quickly adapting to cables of different diameters, which is convenient, fast, time-saving and labor-saving.

[0018] The controllable movement and braking of the detection device can adjust the position of the detection device relative to the cable, allowing it to get closer to the cable fault point as needed, thus facilitating the identification of the fault point and subsequent maintenance. The adjustment of the position can also facilitate the verification of its measurement accuracy, thereby improving the detection accuracy.

[0019] By setting up elastic elements, the elastic elements can undergo elastic deformation when the wind pushes the support frame to swing and the upper and lower fasteners swing due to the inertial swing of the support ring caused by the wind. This consumes energy to perform work, achieves a damping effect, reduces the impact of cable swaying, and helps maintain the stability of its position relative to the cable.

[0020] As the support ring swings, it drives the brush to move back and forth, thereby cleaning the surface of the photovoltaic panel with the brush bristles, reducing dust accumulation, ensuring that the photovoltaic panel can receive sunlight well, improving the stability of power generation, and increasing the power supply options when combined with the wind turbine.

[0028] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] like Figures 1-6As shown, a broadband synchronous detection system based on traveling wave dual-end positioning includes detection devices. Detection devices are installed at both ends of the same linear cable. The two detection devices communicate wirelessly. Each detection device includes an upper latching seat 1, a lower latching seat 2, a locking element 3, and an electrical control system. The upper latching seat 1 and the lower latching seat 2 are hinged to each other at the rear to open and close relative to the cable. After engagement, the upper latching seat 1 and the lower latching seat 2 can form a cylindrical structure to insert the cable. The virtual axis of the cylindrical structure is parallel to the virtual hinge axis of the upper latching seat 1. The locking element 3 includes a bidirectional lead screw 5, a handwheel 6, a compression spring 7, and an insertion cylinder 8. The lower latching seat 2 is rotatably connected to the bidirectional lead screw 5. The bidirectional lead screw 5 is coaxially fixed with a handwheel 6 and is parallel to the cylindrical structure. The handwheel 6 is rigidly connected coaxially in the middle of the bidirectional lead screw 5. The left and right sides of the bidirectional lead screw 5 are each threaded with a plug 8. The two plugs 8 are slidably connected to the lower fastening seat 2. The left and right sides of the upper fastening seat 1 are respectively provided with insertion holes 9. The two plugs 8 can be inserted into and detached from the insertion holes 9 respectively. The left and right sides of the bidirectional lead screw 5 are respectively interleaved with a compression spring 7. The two ends of the compression spring 7 abut against the handwheel 6 and the plug 8 respectively. The two plugs 8 tend to move away from each other under the elastic repulsive force of the compression spring 7. The electrical control system performs broadband traveling wave synchronous detection on the cable.

[0030] In use, the hinged connection between the upper snap-fit ​​seat 1 and the lower snap-fit ​​seat 2 allows the cable to be easily inserted into the cylindrical structure. By rotating the forward and reverse handwheel 6 and the bidirectional lead screw 5, the two plug cylinders 8 can be moved closer and further apart. When the two plug cylinders 8 are close enough, they can disengage from the socket 9, making it easy to remove the detection device from the cable. When the two plug cylinders 8 are far apart, they can be inserted into the socket 9, making it easy to install the detection device outside the cable. Due to the use of the compression spring 7, the two plug cylinders 8 always tend to be inserted into the socket 9, thus preventing accidental disengagement due to thermal expansion and contraction and improving detection stability.

[0031] The upper snap-fit ​​seat 1 and the lower snap-fit ​​seat 2 are respectively slidably connected to lifting seats 10. Each lifting seat 10 is rigidly connected to the upper snap-fit ​​seat 1 and the lower snap-fit ​​seat 2 by a second compression spring 11. Each lifting seat 10 is rotatably connected to a V-shaped roller 12. The axis of the V-shaped roller 12 is spatially perpendicular to the axis of the cylindrical structure. Under the elastic repulsive force of the second compression spring 11, the lifting seats 10 where the upper snap-fit ​​seat 1 and the lower snap-fit ​​seat 2 are located tend to move closer to each other in the vertical direction, so that the V-shaped roller 12 can roll and rub against the outer wall of the cable. The detection device also includes an electric rotary drive mechanism, which is electrically connected to the electrical control system.

[0032] Under the elastic repulsive force of the second compression spring 11, the two lifting seats 10 tend to move closer to each other, which enables the V-shaped roller 12 to clamp the cable, thereby quickly adapting to cables of different diameters, which is convenient, fast, time-saving and labor-saving.

[0033] The electric rotary drive mechanism includes a dual-axis servo motor 13, a worm gear 14, an upper drive shaft 15, a worm wheel 16, a lower drive shaft 17, an upper slot 18, an upper limit slot 19, a lower slot 21, a lower limit slot 22, a connecting plate 24, a connecting pin 25, and a transmission mechanism. The dual-axis servo motor 13 is fixed to the upper part of the upper fastening seat 1. The worm gear 14 is rigidly connected to both ends of the axial shaft of the dual-axis servo motor 13 coaxially. The worm gear 14 is connected to the upper fastening seat. The upper snap-fit ​​seat 1 is rotatably connected to two vertical upper drive shafts 15 on its left and right sides. Each of the two upper drive shafts 15 is coaxially fixed with a worm gear 16, which meshes with a worm 14. The lower snap-fit ​​seat 2 is rotatably connected to two vertical lower drive shafts 17 on its left and right sides. When the upper snap-fit ​​seat 1 and the lower snap-fit ​​seat 2 are engaged, the lower drive shafts 17 and the upper drive shafts 15 are coaxially aligned. Each upper drive shaft 15 has an upper slot 18 at its bottom end. The upper drive shaft 15 has a vertical slot 21 at its top and a lower limit slot 22 extending through it. The upper drive shaft 17 is connected to the upper drive shaft 15 from front to back. The upper drive shaft 15 and the lower drive shaft 17 are connected to a connecting plate 24. The upper and lower parts of the connecting plate 24 are rigidly connected to the upper and lower parts of the connecting plate 24 from left to right. The upper and lower parts of the connecting plate 24 are respectively inserted into the upper slot 18 and the lower slot 21 with a gap. The connecting pins 25 on the upper and lower parts of the connecting plate 24 are respectively inserted into the upper limit slot 19 and the lower limit slot 22 with a gap. The connecting plate 24 can swing back and forth and move up and down along the upper slot 18 and the lower slot 21. The connecting pins 25 can rotate and move up and down within the upper limit slot 19 and the lower limit slot 22. The upper drive shaft 15 and the lower drive shaft 17 are connected to each V-shaped roller 12 through a transmission mechanism.

[0034] Furthermore, by controlling the rotation of the dual-axis servo motor 13, the meshing of the worm gear 14 and worm wheel 16 causes the upper drive shaft 15 to rotate, which in turn drives the lower drive shaft 17 to rotate via the connecting plate 24 and connecting pin 25. This, in turn, drives the V-shaped rollers 12 on both sides of the cable to rotate in opposite directions via the transmission mechanism, thus enabling movement along the cable. When the dual-axis servo motor 13 stops rotating, the self-locking characteristic of the worm gear 14 and worm wheel 16 transmission enables braking. This controllable movement and braking can adjust the position of the detection device relative to the cable, allowing it to get closer to the cable fault point as needed, facilitating fault point identification and subsequent maintenance. The position adjustment also facilitates the verification of its measurement accuracy, improving detection accuracy. When it is necessary to disassemble or assemble the detection device relative to the cable, the dual-axis servo motor 13 is rotated at a certain angle so that the connecting pin 25 is parallel to the virtual axis of the cylindrical structure. At this time, the connecting plate 24 can move up and down along the upper slot 18 and lower slot 21 as the upper snap-fit ​​seat 1 and lower snap-fit ​​seat 2 open and close.

[0035] The transmission mechanism includes an upper adjusting groove 27, a lower adjusting groove 28, a bushing 29, a transmission rod 30, a driving bevel gear 31, and a driven bevel gear 32. The upper transmission shaft 15 passes through the upper adjusting groove 27 on both sides, and the lower transmission shaft 17 passes through the lower adjusting groove 28 on both sides. The upper transmission shaft 15 and the lower transmission shaft 17 are axially slidably connected to bushings 29, and each bushing 29 is axially rigidly connected to a transmission rod 30. The transmission rod 30 is interleaved with the upper adjusting groove 27 or the lower adjusting groove 28 and can move up and down along the upper adjusting groove 27 and the lower adjusting groove 28. Each bushing 29 is rotatably connected to the lifting seat 10. Each bushing 29 is coaxially fixed with a driving bevel gear 31, and each V-shaped roller 12 is coaxially fixed with a driven bevel gear 32. Each driving bevel gear 31 meshes with each driven bevel gear 32.

[0036] Furthermore, when the upper drive shaft 15 and the lower drive shaft 17 rotate, the bushing 29 and the transmission rod 30 can drive the active bevel gear 31 to rotate together with the upper drive shaft 15 and the lower drive shaft 17. Thus, the meshing of the active bevel gear 31 and the driven bevel gear 32 enables the V-shaped rollers 12 on the upper and lower sides of the cable to rotate in opposite directions, that is, to move along the cable. Since the cables are of different thicknesses, when the lifting seats 10 move closer to each other and further away from each other, the bushing 29 can move with the lifting seats 10 through the cooperation of the transmission rod 30 with the upper adjustment groove 27 and the lower adjustment groove 28 to adapt to cables of different thicknesses.

[0037] The electrical control system includes a wideband open-type current transformer 33, which includes a front half 34, a rear half 35, a first pin 36, and a first tension spring 37. The front half 34 and the rear half 35 are respectively inserted into the upper snap-fit ​​seat 1 and the lower snap-fit ​​seat 2 to form a complete ring with the internal magnetic core. The first pin 36 is slidably connected to the front half 34 and the rear half 35. The two first pins 36 are rigidly connected to the front half 34 and the rear half 35 respectively by a first tension spring 37. Under the elastic tension of the first tension spring 37, the two first pins 36 tend to move closer to each other and can be inserted into the upper snap-fit ​​seat 1 and the lower snap-fit ​​seat 2 respectively. The wideband open-type current transformer 33 is electrically connected to the electrical control system.

[0038] The electronic control system also includes a support component, a support frame 39, a wind turbine generator 40, a guide vane 41, and a conductive slip ring 42. The upper fastening seat 1 and the lower fastening seat 2 are detachably mounted on the right side of the support component. The bottom of the support component is rotatably connected to the vertical support frame 39. The virtual axis of the support frame 39 is set vertically. The wind turbine generator 40 is fixed inside the support frame 39, and the guide vane 41 is fixed at the rear. The guide vane 41 is radially arranged relative to the virtual axis of the support frame 39. The wind turbine generator 40 and the guide vane 41 are aligned front and rear. The support component is equipped with a conductive slip ring 42. The rotor of the conductive slip ring 42 is rigidly connected to the support frame 39, and the stator is rigidly connected to the support component. The stator of the conductive slip ring 42 is electrically connected to the power processing module and the battery of the electronic control system, and the rotor is electrically connected to the wind turbine generator 40.

[0039] When the external wind blows the guide vane 41, it can cause the wind turbine 40 to face the wind direction to generate electricity. The generated electricity is processed by the power processing module and stored in the battery for easy access by electrical appliances such as the dual-axis servo motor 13.

[0040] The support component includes a support housing 43, a locking mechanism, a support ring 45, and an elastic element 46. The support housing 43 is inserted into the cylindrical structure from left to right and from right to left through the locking mechanism. The support ring 45 is rotatably connected to the support housing 43. The virtual axis of rotation of the support ring 45 is coaxial with that of the cylindrical structure. Elastic elements 46 are respectively installed between the front and rear parts of the support ring 45 and the support housing 43. The support frame 39 is rotatably connected to the support ring 45. The conductive slip ring 42 is installed with the support ring 45. Under the elastic force of the elastic element 46, the support ring 45 tends to drive the support frame 39 back to a vertically downward position. The upper part of the support housing 43 and the upper part of the support ring 45 are respectively provided with openings for cables to pass through. The elastic element 46 is a tension spring or a compression spring, etc.

[0041] By setting the elastic element 46, the elastic element 46 can undergo elastic deformation when the wind pushes the support frame 39 to swing the support ring 45, and when the upper fastening seat 1 and the lower fastening seat 2 are blown by the wind and the support ring 45 swings inertia. This consumes energy to perform work, achieves a damping effect, reduces the impact on the cable's sway, and helps maintain its position relative to the cable's stability.

[0042] An arc-shaped photovoltaic panel 47 is fitted and fixed to the outer circumferential wall of the upper fastening seat 1. Brushes 48 are fixed to the front and rear parts of the support ring 45. The bristles of the brushes 48 are in contact with the surface of the photovoltaic panel 47. The photovoltaic panel 47 is electrically connected to the power processing module and the battery of the power control system. This power processing module is a wind-solar hybrid controller, which includes conventional functions such as rectification of the wind turbine 40, unloading protection of the wind turbine 40, voltage stabilization of the photovoltaic panel 47, three-stage charging of the battery, overcharge protection, over-discharge protection, reverse connection protection and short circuit protection.

[0043] Furthermore, when the support ring 45 swings, it can drive the brush 48 to move back and forth, thereby using the brush bristles to clean the surface of the photovoltaic panel 47, reducing the accumulation of dust, ensuring that the photovoltaic panel 47 can receive sunlight well, improving the stability of power generation, and at the same time, in conjunction with the wind turbine 40, increasing the power supply options.

[0044] The locking mechanism includes a second pin 49 and a second tension spring 50. The second pin 49 is slidably connected to the front and rear parts of the support housing 43. The two second pins 49 are rigidly connected to the support housing 43 by the second tension spring 50. Under the elastic tension of the second tension spring 50, the two second pins 49 tend to move closer to each other and can be inserted into the upper fastening seat 1 and the lower fastening seat 2.

[0045] Furthermore, by manually pulling pin 36 and pin 49, it can be easily disengaged from upper connector 1 and lower connector 2. Then, the wideband open-type current transformer 33 and support housing 43 can be pulled to disengage from upper connector 1 and lower connector 2, which is convenient and quick.

[0046] The electronic control system includes a GPS / BeiDou dual-mode timing module, an STM32 / ARM main control module, a wireless communication module, a high-speed wideband operational amplifier circuit, a traveling wave signal conditioning circuit, a high-speed ADC, and a power supply.

[0047] The GPS / BeiDou dual-mode timing module provides absolute time. The STM32 / ARM main control module, as the main control chip, is responsible for overall scheduling, controlling the high-speed ADC, processing data, parsing GPS / BeiDou data, driving the wireless communication module, and performing calculations. The wireless communication module can use a LoRa433MHz wireless serial port module for wireless data transmission. The high-speed wideband operational amplifier circuit and traveling wave signal conditioning circuit are used to amplify weak signals, filter, resist interference, and match impedance to ensure high-frequency distortion-free operation. The high-speed ADC is responsible for converting analog signals into digital signals at high speed to achieve high-speed acquisition. The power supply should have low ripple and anti-interference functions. All of the above modules are known existing technologies and are conventional technologies in the field of traveling wave detection technology. Their working principles will not be elaborated further.

[0048] The above description represents a preferred embodiment of the present invention. For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of the present invention, based on the teachings of the present invention, still fall within the protection scope of the present invention.
