Description

Technical Field

[0001] This utility model relates to a receiving module for an RTK pipeline instrument, and more specifically, this utility model mainly relates to a 3D magnetic rod coil module for an RTK pipeline instrument. Background Technology

[0002] An RTK pipeline receiver provides high-precision geographic location (longitude, latitude, and elevation), path direction, and depth detection for underground pipelines, including power cables, communication optical cables, railway control cables, gas pipes, oil pipelines, water pipes, and municipal water supply and drainage pipes. It also integrates multiple cable identification functions. Currently, there is no single efficient and practical instrument for underground pipeline surveying. Geographic location mapping is typically achieved using a standard pipeline receiver combined with an external RTK mapping handheld device, requiring at least three people: one to hold the receiver, one to hold the handheld device and antenna, and one to operate the transmitter. This is labor-intensive, inconvenient, and inefficient. Furthermore, standard pipeline receivers are inaccurate in complex scenarios with multiple intersecting pipelines or cables, or cannot accurately detect the location, path, and depth of a specific cable underground. Therefore, further research and improvement of the specific structure of RTK pipeline instruments are necessary. Utility Model Content

[0003] One of the objectives of this invention is to address the aforementioned shortcomings by providing a 3D magnetic rod coil module for RTK pipeline instrumentation, thereby resolving technical problems in the prior art such as inaccurate signal reception from the transmitter, which affects the accuracy of path and depth detection of underground metal pipelines.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] This utility model provides a 3D ferrite rod coil module for an RTK pipeline instrument, comprising a module body for installation within the receiver housing of the RTK pipeline instrument. The module body includes an X-axis ferrite rod coil, a Y-axis ferrite rod coil, and a Z-axis ferrite rod coil. The X-axis ferrite rod coil is wound on an X-axis coil frame, the Y-axis ferrite rod coil is wound on a Y-axis coil frame, and the Z-axis ferrite rod coil is wound on a Z-axis coil frame. The Z-axis coil frame is annular, and the X-axis and Y-axis coil frames are respectively installed at the upper and lower parts of the Z-axis coil frame, forming a three-dimensional intersection. The X-axis, Y-axis, and Z-axis ferrite rod coils are respectively connected to the PCB control board of the RTK pipeline instrument receiver.

[0006] As a preferred embodiment, a further technical solution is: the module body consists of two parts, which are respectively installed in the upper and lower parts of the receiver housing of the RTK pipeline instrument. The X-axis magnetic rod coil, Y-axis magnetic rod coil and Z-axis magnetic rod coil of each of the two module bodies are respectively connected to the PCB control board of the receiver of the RTK pipeline instrument.

[0007] A further technical solution is that the PCB control board of the receiver of the RTK pipeline instrument is also connected to a positioning chipset and a communication module. The positioning chipset and the communication module are both installed inside the housing of the receiver of the RTK pipeline instrument. The communication module includes two 4G / 5G modules, a Bluetooth module and a Beidou positioning module.

[0008] A further technical solution is: the X-axis coil frame and the Y-axis coil frame are cylindrical, the Z-axis coil frame is annular, and the annular Z-axis coil frame is provided with a mounting platform in the middle, the mounting platform separating the X-axis coil frame and the Y-axis coil frame vertically.

[0009] A further technical solution is that the X-axis coil frame and the Y-axis coil frame intersect each other in a three-dimensional cross shape.

[0010] Compared with the prior art, one of the beneficial effects of this utility model is that by designing a magnetic rod coil module with XYZ three-dimensional signal acquisition, the location of underground pipelines can be detected from three-dimensional direction, with higher detection accuracy, thereby effectively improving the accuracy of the RTK pipeline instrument in detecting the path and depth of underground metal pipelines.

Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] refer to Figure 1 As shown, one embodiment of this utility model is a 3D magnetic rod coil module for an RTK pipeline instrument. This 3D magnetic rod coil module is used in the receiver of the RTK pipeline instrument to improve the accuracy of its acquisition of transmitter signals, thereby improving the accuracy of underground metal pipeline detection. This is an integral structure, referred to as module body 1 in this embodiment for ease of description. Module body 1 is installed inside the receiver housing 2 of the RTK pipeline instrument. Module body 1 includes three signal acquisition coils: an X-axis magnetic rod coil 11, a Y-axis magnetic rod coil 12, and a Z-axis magnetic rod coil 13. The X-axis magnetic rod coil 11 is wound on the X-axis coil frame 14, the Y-axis magnetic rod coil 12 is wound on the Y-axis coil frame 15, and the Z-axis magnetic rod coil 13 is wound on the Z-axis coil frame 16. More importantly, to ensure the integrity of the module structure, the Z-axis coil frame 16 can be designed as a ring. Then, the X-axis coil frame 14 and the Y-axis coil frame 15 are respectively installed on the upper and lower parts of the ring-shaped Z-axis coil frame 16, making the X-axis coil frame 14 and the Y-axis coil frame 15 intersect in a three-dimensional manner, that is, they intersect each other on the vertical plane, not actually intersecting. Figure 1 As shown, the two intersect in a three-dimensional cross shape; just as Figure 2 As shown, the aforementioned X-axis ferrite coil 11, Y-axis ferrite coil 12, and Z-axis ferrite coil 13 are respectively connected to the PCB control board 3 of the receiver of the RTK pipeline instrument. As... Figure 1 As shown, preferably, the X-axis coil frame 14 and Y-axis coil frame 15 are designed as cylindrical, and the Z-axis coil frame 16 is designed as an annular shape. The X-axis coil frame 14 and Y-axis coil frame 15 are installed inside the annular Z-axis coil frame 16, and a mounting platform 7 is provided in the middle of the annular Z-axis coil frame 16. The mounting platform 7 separates the X-axis coil frame 14 and Y-axis coil frame 15 vertically to avoid mutual interference. At the same time, the circuits in the mounting platform perform detection processing on the signals collected by each coil and then transmit them to the PCB control board 3.

[0017] In this embodiment, by designing a magnetic rod coil module with XYZ three-dimensional signal acquisition, the location of underground pipelines can be detected from three dimensions, resulting in higher detection accuracy and effectively improving the accuracy of the RTK pipeline instrument in detecting the path and depth of underground metal pipelines.

[0018] Based on the structure of the module body described in the above embodiments, two module bodies 1 with the same structure can be set up in application, just as... Figure 3 As shown, the two module bodies 1 mentioned above are respectively installed in the upper and lower parts of the receiver housing 2 of the RTK pipeline instrument, as follows: Figure 2As shown, the X-axis magnetic rod coil 11, Y-axis magnetic rod coil 12, and Z-axis magnetic rod coil 13 of each of the two module bodies 1 are respectively connected to the PCB control board 3 of the receiver of the RTK pipeline instrument. That is, in this embodiment, two sets of 3D magnetic rod coil antennas are used to receive the transmitted signals generated by the transmitter on the pipeline, which can improve the detection efficiency.

[0019] As Figure 2 As shown, the inventors considered the structure of a typical RTK pipeline receiver and further connected the aforementioned PCB control board 3 to a positioning chipset and communication module. The aforementioned positioning chipset can employ an RTK geographic location positioning chip and module, and as shown... Figure 3 The positioning chipset and communication module are both installed inside the receiver housing 2 of the RTK pipeline instrument. The aforementioned communication module includes two 4G / 5G modules 4, a Bluetooth module 5, and a Beidou positioning module 6. That is, each module can perform its inherent function during receiver use.

[0020] Based on the structure shown in the above embodiment, the magnetic rod coil 11 in the X-axis direction of the module body jointly detects and calculates the depth of the target cable underground; the magnetic rod coil 12 in the Y-axis direction jointly detects and calculates the left and right offset distance of the target cable; and the coil 13 in the Z-axis direction jointly detects and calculates the angle between the conductor and the Y-axis direction. Two sets of 3D magnetic rod coil module antennas, combined with the algorithm, can accurately detect the location and depth of underground pipelines. Furthermore, each of the XYZ coil groups consists of multiple coils. For example, the X-group coil has a frame divided into four parts, with magnetic rods installed inside. Each part is wound with one set of coils, and multiple sets of coils are connected in series according to different receiving frequencies for better reception of signals of different frequencies. The Y-group coil is similar; the Z-group coil is also similar, with a circular frame designed with layers, allowing coils with different numbers of turns to be wound on each layer. The purpose is to better match different receiving frequencies, making the received signal stronger and more effective, facilitating analysis and calculation.

[0021] The RTK pipeline detector receiver described in this invention is used to receive various frequency signals sent by the transmitter to the underground pipeline, and to receive the signals on the ground. This allows for the detection of the pipeline's underground path, depth, location, and RTK millimeter-level satellite geolocation. The receiver, connected to a flexible coil, can identify the cable at any wellhead at either end or in the middle of the cable. Connecting the receiver to an A-bracket allows for fault location of the cable.

[0022] The RTK pipeline locator receiver, which also utilizes a 3D magnetic rod coil module, features the following characteristics: The receiver incorporates two sets of 3D magnetic rod coils, allowing for three-dimensional detection of underground pipeline locations with greater depth accuracy. An integrated RTK millimeter-level geolocation module enables high-precision positioning of underground pipelines. A built-in gyroscope horizontal positioning chip facilitates GNSS measurement tilt correction; users simply press a button and tilt the receiver to acquire precise GNSS coordinates, achieving millimeter-level geolocation. Two built-in 4G / 5G modules serve two purposes: firstly, to rapidly transmit all data from each geographic point in the pipeline mapping to the server for data processing; and secondly, to control the transmitter's start / stop, output power, transmission frequency, and operating mode, allowing remote monitoring and control of the transmitter's status and reducing manual operation at the transmitter end. The receiver also features both touch and button operation capabilities.
