Description

Technical Field

[0001] This invention relates to the field of geotechnical engineering monitoring technology, and in particular to a tilt measuring device, a tilt measuring system, and a method for judging the validity of measurement data. Background Technology

[0002] The sliding inclinometer, also known as a borehole inclinometer or a movable inclinometer, is a typical geotechnical engineering monitoring instrument. It is highly effective for deformation monitoring in the field of geotechnical engineering. It is widely used by water conservancy, highway, railway, seaport, construction, power, mining and other units in rock mass civil engineering, especially in the fields of earth-rock dams, dikes, rock and soil slopes, building foundations, mines, foundation pit excavation, and internal horizontal displacement observation and roadbed profile settlement observation of underground structures.

[0003] The sliding inclinometer uses a high-precision accelerometer as its core component. The probe moves within the guide groove of the inclinometer tube inside the borehole, and the horizontal displacement of each measurement point relative to the bottom of the borehole can be calculated. The sliding inclinometer mainly consists of a control cable, a data acquisition and transmission device, and the probe. Currently, the control cable of inclinometers in the industry generally consists of a calibration cable (with a marking ring providing depth scale), a lower cable connector (large end), an upper cable connector (small end), and a wellhead positioning device. Its functions include powering the probe (occupying at least two cable conductors), providing an output path for data (generally using RS485 communication, occupying two cable conductors), providing a depth measurement benchmark, and manipulating the probe to enter and exit the borehole. To meet the above functional requirements, current inclinometer cables in the industry typically have four or more cores, with a diameter of 8-10mm and a standard cable length of 50m. For example, the cable of the CX-06B inclinometer weighs 5.5kg, and in some deep holes it can be as long as 300m, further increasing the cable weight. This weight significantly impacts the portability of the equipment and increases costs. Furthermore, in the specialized field of geotechnical engineering monitoring, long-term adaptability to sediment, acid, alkali, and saline environments is one of the core performance characteristics of the equipment. However, current inclinometers use wired communication and wired charging, and employ mechanical switches with several exposed electrical connectors, making it difficult to ensure sealing. Sediment can easily enter the electrical connectors or data acquisition components, severely affecting their service life. In addition, traditional inclinometer data is generally processed locally via wired means (such as serial ports), and the data is processed manually. The data collected by traditional inclinometers is related to its own sensor parameters, electrical parameters and mechanical structure, as well as the inclinometer tube, operating conditions and personnel operation. In engineering practice, it is difficult for people to find problematic data on site, and invalid data is often obtained, which leads to returning to the site for remeasurement. There is an urgent need for intelligent analysis of inclinometer data on site. Summary of the Invention

[0004] To address one of the problems existing in the prior art, the present invention provides an inclinometer device, an inclinometer system, and a method for judging the validity of measurement data.

[0006] When the power conversion circuit and the power supply bus master circuit are in the ON state, the rechargeable battery supplies power to the microcontroller and the power supply bus master circuit through the power conversion circuit, and supplies power to the probe through the power supply bus master circuit, cable and power supply bus slave circuit. The microcontroller transmits command data to the probe through the power supply bus master circuit, cable and power supply bus slave circuit, and the probe transmits measurement data to the microcontroller through the power supply bus slave circuit, cable and power supply bus master circuit.

[0007] When the power conversion circuit and the power supply bus master circuit are in the off state, the rechargeable battery stops supplying power to the microcontroller, the power supply bus master circuit and the probe, the microcontroller stops transmitting command data to the probe, and the probe stops transmitting measurement data to the microcontroller.

[0008] Furthermore, the repeater also includes a wireless charging coil and / or a wired charging and discharging line, and the acquisition circuit also includes a charging and discharging management module. The charging and discharging management module is connected to the rechargeable battery and the wireless charging coil and / or the wired charging and discharging line.

[0009] Furthermore, the acquisition circuit also includes a magnetic reed switch circuit, which is used to activate the microcontroller in conjunction with a magnet.

[0010] Furthermore, the acquisition circuit also includes a Bluetooth module, which is used to transmit command data to the microcontroller and measurement data to the mobile terminal.

[0011] Furthermore, the repeater also includes a sealed housing, which includes a housing body and a sealing cover. The sealing cover is sealed on the housing body to form a sealed cavity. The acquisition circuit, rechargeable battery, wireless charging coil and / or wired charging and discharging line are placed in the sealed cavity. The housing body is provided with a waterproof connector, and the cable is connected to the power supply bus master circuit through the waterproof connector.

[0012] Furthermore, the sealed box also includes a cylindrical storage section with openings at both ends and a storage section end cap. The outer wall surface of the cylindrical storage section has threads. One end of the cylindrical storage section is connected to the box body, and the other end is connected to the storage section end cap through threads. The port of the wired charging and discharging cable passes through the box body and is located inside the cylindrical storage section.

AD and the standard deviation of the sum of the data in direction B S BD If all measurements are within the preset range, the measurement data is considered valid; otherwise, the measurement data is considered invalid.

[0020] Furthermore, through SV Ai =V A0i +V A180i Calculate the A-axis data and SV value corresponding to each depth point in the borehole. Ai V A0i V represents the measurement data in the direction of the i-th depth point A0. A180i This represents the measurement data of the i-th depth point in the A180 direction, expressed via SV. Bi =V B0i +V B180i Calculate the data and value SV in direction B. Bi V B0iV represents the measurement data in the direction of the i-th depth point B0.

AD ,pass Calculate the standard deviation S of the sum of data in direction B. BD , where I represents the number of depth points.

[0021] Furthermore, the preset range is 0.02 to 0.2 mm.

[0022] The present invention provides an inclinometer device, an inclinometer system, and a method for determining the validity of measurement data.

[0030] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0032] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0033] Please refer to Figure 1 and Figure 2According to a specific embodiment of the present invention, an inclinometer is provided. The inclinometer includes a repeater 10, a probe 20, and a cable 30. The repeater 10 includes a data acquisition circuit and a rechargeable battery 11. The data acquisition circuit includes a microcontroller, a power conversion circuit, and a power supply bus master circuit. The data acquisition circuit controls the power conversion circuit and the power supply bus master circuit to turn on and off through the microcontroller. The probe 20 includes a power supply bus slave circuit. One end of the cable 30 is connected to the power supply bus master circuit, and the other end is connected to the power supply bus slave circuit.

[0034] When the power conversion circuit and the power supply bus master circuit are in the on state, the rechargeable battery 11 supplies power to the microcontroller and the power supply bus master circuit through the power conversion circuit, and supplies power to the probe 20 through the power supply bus master circuit, cable 30 and power supply bus slave circuit. The microcontroller transmits command data to the probe 20 through the power supply bus master circuit, cable 30 and power supply bus slave circuit, and the probe 20 transmits measurement data to the microcontroller through the power supply bus slave circuit, cable 30 and power supply bus master circuit.

[0035] When the power conversion circuit and the power supply bus master circuit are in the off state, the rechargeable battery 11 stops supplying power to the microcontroller, the power supply bus master circuit and the probe 20, the microcontroller stops transmitting instruction data to the probe 20, and the probe 20 stops transmitting measurement data to the microcontroller.

[0036] This configuration provides a tilt measuring device. The device incorporates a rechargeable battery 11 and a data acquisition circuit within a repeater 10. The data acquisition circuit includes a microcontroller, a power conversion circuit, and a master power supply bus circuit. A slave power supply bus circuit is integrated into the probe 20. A cable 30 connects the master and slave circuits, enabling modulation of control signals on the power cable. This replaces the traditional separate control and power cables, combining the power and communication lines into one. The number of conductor cores in the cable 30 is reduced to two, significantly decreasing its size and weight, improving portability, and reducing the cost of the tilt measuring instrument. Furthermore, the power supply bus offers non-polarity wiring with arbitrary topology, preventing wiring errors during production. Compared to existing technologies, this invention solves the problems of large cable size, heavy weight, high cost, and poor portability in tilt measuring devices.

[0037] In a specific embodiment of the present invention, the power supply bus adopts a low-voltage DC carrier power supply bus. The cable includes two conductor cores and three Kevlar cores, with an outer diameter of 6mm. Red and yellow marking rings are injection-molded onto the cable surface at 500mm intervals. The marking ring dimensions are: outer diameter 10±0.2mm, center width 20±1.0mm, and total width 26±1.0mm, transitioning evenly to the sheath surface at both ends. By reducing the cable's outer diameter and the number of metal cores, cable weight reduction can be achieved.

[0038] Furthermore, in this invention, the repeater 10 also includes a wireless charging coil 12 and / or a wired charging and discharging line, and the acquisition circuit also includes a charging and discharging management module. The charging and discharging management module is connected to the rechargeable battery 11 and the wireless charging coil 12 and / or the wired charging and discharging line. The acquisition circuit enables the charging and discharging management module through a microcontroller to connect the rechargeable battery 11 with the wireless charging coil 12 and / or the wired charging and discharging line.

[0039] This configuration allows for both wired and wireless charging. The wireless charging solution is beneficial for waterproofing and usability. For a specific embodiment of this invention, please refer to... Figure 6 This circuit diagram example for the charging and discharging management module demonstrates that since wired charging is generally more efficient than wireless charging, a wired charging priority strategy is adopted when both wired and wireless charging are present. When wired charging is active on the TYPEC, Qi_CHG_ON transitions from a high level to a low level, disabling wireless charging and thus resolving the intelligent switching between wired and wireless modes. This circuit is compatible with both wireless and wired charging, and the transition from wired to wireless occurs without human intervention, achieving intelligent switching between the two modes.

[0040] Furthermore, the acquisition circuit also includes a magnetic reed switch circuit, which is used to activate the microcontroller in conjunction with a magnet. This invention uses a magnetic reed switch instead of a traditional mechanical switch to activate the microcontroller in the acquisition circuit. When an external magnet approaches the magnetic reed switch, the reed switch engages, and the low-power microcontroller powers on. This non-contact activation method overcomes the sealing and lifespan issues of mechanical switches.

[0041] Furthermore, to facilitate data transmission and sharing, the acquisition circuit in this invention also includes a Bluetooth module. The Bluetooth module is used to transmit command data to the microcontroller and measurement data to the mobile terminal. Here, the mobile terminal can be a mobile device with communication capabilities, such as a mobile phone, computer, or tablet.

[0042] Further, please refer to, for example Figure 3In this example, the repeater 10 also includes a sealed housing 13, which includes a housing body 131 and a sealing cover 132. The sealing cover 132 is sealed on the housing body 131 to form a sealed cavity. The acquisition circuit, the rechargeable battery 11, and the wireless charging coil 12 and / or the wired charging and discharging line are disposed in the sealed cavity. A waterproof connector 131a is provided on the housing body 131, and the cable 30 is connected to the power supply bus master circuit through the waterproof connector 131a.

[0043] This configuration allows for the sealing of the acquisition circuit, rechargeable battery 11, and wireless charging coil 12 and / or wired charging / discharging cable, improving the repeater's portability and adaptability to geotechnical engineering environments. Furthermore, to facilitate wireless charging, such as... Figure 4 and Figure 5 As shown, the sealed box 13 has a rectangular shape with flat sides. The wireless charging coil 12 is fixed and closely attached to the side wall of the box body 131 for receiving electromagnetic waves for wireless charging. Multiple rechargeable batteries 11 form a battery pack, which is set in the sealed cavity.

[0044] Furthermore, the sealed box 13 also includes a cylindrical storage portion 133 with openings at both ends and a storage portion end cap 134. The outer wall surface of the cylindrical storage portion 133 has threads 133a. One end of the cylindrical storage portion 133 is connected to the box body 131, and the other end is connected to the storage portion end cap 134 via threads 133a. The port 14 of the wired charging / discharging cable passes through the box body 131 and is disposed inside the cylindrical storage portion 133. With this configuration, a sealed storage chamber is formed at the end of the sealed box 13. This storage chamber can not only provide the external charging / discharging port 14 but also store the charging cable, thus achieving overall sealing of the repeater 10 in conjunction with the sealed box 13. As a specific embodiment of the present invention, the port 14 is a Type-A / C port, which can both provide wired fast charging for the rechargeable battery 11 in the repeater 10 and provide power as a power bank, making it convenient for charging portable devices such as mobile phones in the field of geotechnical engineering. Furthermore, to ensure the overall airtightness of the sealed housing 13, the shape of the storage end cap 134 conforms to the shape of the housing body 131. The thread 133a is a tightening and positioning thread, and the cylindrical storage part 133 has a tightening and positioning part 133b on both sides of the bottom. After tightening, it ensures airtightness while facilitating the alignment of the storage end cap 134 with the cuboid shape of the housing body 131, maintaining the cuboid shape of the repeater. In this invention, all connecting parts are equipped with rubber sealing rings for sealing. This dual-cavity design facilitates the charging function of the storage chamber and ensures the airtightness of the front sealed cavity, significantly improving the portability of the inclinometer and its adaptability to geotechnical engineering environments.

[0045] According to another aspect of the present invention, an inclinometer system is provided, comprising the inclinometer device, mobile terminal, cloud platform, and data management unit as described above. Command data is issued by the mobile terminal, measurement data is transmitted to the mobile terminal and uploaded to the cloud platform via the mobile terminal, and the data management unit is used to obtain and process the measurement data from the cloud platform.

[0046] The inclinometer system uses the inclinometer device proposed above. The repeater 10 uses power supply bus technology to receive and respond to command data from mobile terminals such as mobile phones, send commands downwards and receive the execution results of the probe 20, realize the acquisition and transmission of measurement data output by the probe 20, provide a channel for data transmission between the probe 20 and the mobile terminal, and automatically upload the measurement data to the cloud platform through the wireless network for easy sharing and processing.

[0047] According to another aspect of the present invention, a method for determining the validity of measurement data is provided, wherein the measurement data is data obtained by the inclinometer device or inclinometer system proposed above, and the method includes:

[0048] Calculate the A-direction data and SV corresponding to each depth point in the borehole based on the A-direction data in the measurement data. Ai ;

[0049] Calculate the B-direction data and SV corresponding to each depth point in the borehole based on the B-direction data in the measurement data. Bi ;

[0050] Calculate the standard deviation S of the A-direction data sum value based on the A-direction data sum value corresponding to each depth point of the borehole. AD ;

[0051] Calculate the standard deviation S of the B-direction data sum value based on the B-direction data sum value corresponding to each depth point of the borehole. BD ;

[0052] Determine the standard deviation S of the sum of the data in direction A. AD and the standard deviation of the sum of the data in direction B S BD If all measurements are within the preset range, the measurement data is considered valid; otherwise, the measurement data is considered invalid.

[0053] This invention innovatively proposes using the standard deviation of the sum to determine the dispersion of measurement data, thereby verifying the validity of the measurement data. The standard deviation of the sum can comprehensively assess the operator's skill level, the accuracy of the inclinometer, and the quality of the inclinometer tube installation. The preset range is determined according to actual needs, for example, a preset range of 0.02–0.2 mm. By comparing with historical data, an alarm value is given on-site. In this way, the validity of measurement data can be quickly determined on-site, avoiding invalid data and requiring remeasurement, thus improving measurement efficiency.

[0054] As a specific embodiment of the present invention, through SV Ai =V A0i +V A180i Calculate the A-axis data and SV value corresponding to each depth point in the borehole. Ai V A0i V represents the measurement data in the direction of the i-th depth point A0. A180i This represents the measurement data of the i-th depth point in the A180 direction, expressed via SV. Bi =V B0i +V B180i Calculate the data and value SV in direction B. Bi V B0i V represents the measurement data in the direction of the i-th depth point B0. B180i This represents the measurement data of the i-th depth point in the B180 direction, obtained through... Calculate the standard deviation S of the sum of the data in direction A. AD ,pass Calculate the standard deviation S of the sum of data in direction B. BD , where I represents the number of depth points.

[0055] In summary, this invention provides an inclinometer device, an inclinometer system, and a method for determining the validity of measurement data. The device incorporates a rechargeable battery and a data acquisition circuit within a repeater. The data acquisition circuit includes a microcontroller, a power conversion circuit, and a master power supply bus circuit. A slave power supply bus circuit is integrated into the probe. Connecting the master and slave circuits via a cable allows for modulation of control signals on the power cable, replacing the traditional separate control and power cables. This integrates the power supply and communication lines, reducing the number of conductor cores in the cable to two, significantly decreasing cable size and weight, improving the portability of the inclinometer device, and substantially reducing the cost of the inclinometer. Furthermore, the power supply bus offers non-polarity wiring with arbitrary topology, preventing wiring errors during production. Compared to existing technologies, this invention solves the technical problems of large cable size, heavy weight, high cost, and poor portability in inclinometer devices.

[0056] In the description of this invention, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is generally based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this invention; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0057] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0058] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore should not be construed as limiting the scope of protection of this invention.

[0059] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
