Description

Technical Field

[0001] This application relates to the field of metrology and testing, and more specifically, to displacement detection devices and systems. Background Technology

[0002] Displacement detection has a wide range of applications, such as slope landslide monitoring, bridge and tunnel crack monitoring, and support column settlement monitoring. Common displacement detection devices include draw-wire displacement meters, which convert mechanical motion into measurable, recordable, or transmittable electrical signals. A draw-wire displacement meter typically consists of a stretchable steel wire rope wound around a threaded hub, which is connected to a precision rotary sensor. The sensor can be an incremental encoder, an absolute encoder, a hybrid or conductive plastic rotary potentiometer, a synchronizer, or a resolver. Operationally, the draw-wire displacement sensor is mounted in a fixed position, with the draw-wire attached to the moving object. The linear motion of the draw-wire is aligned with the axis of motion of the moving object. During motion, the draw-wire extends and contracts. An internal spring ensures that the tension of the draw-wire remains constant. The threaded hub drives the precision rotary sensor to rotate, outputting an electrical signal proportional to the distance the draw-wire has moved. The use and installation conditions of draw-wire displacement gauges are quite demanding. For example, the wire rope must be kept clean, and during installation, it must be pulled out vertically to prevent friction at the outlet. The wire rope should be pulled out as perpendicularly as possible to the outlet, maintaining a minimum deviation angle (≤3°) to ensure measurement accuracy and wire rope life. If used on non-linear motion mechanisms, a steering mechanism is also required. Furthermore, draw-wire displacement gauges are not suitable for scenarios where vertical and horizontal displacements exist simultaneously (such as monitoring vertical settlement and horizontal cracks between viaduct piers and the ground), as they cannot simultaneously detect both vertical and horizontal displacements.

[0021] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.

[0024] The terms "first," "second," "object one," "object two," etc., used in the specification and drawings of this application are used to distinguish different objects or to distinguish different treatments of the same object, rather than to describe a specific order of objects.

[0025] Furthermore, the terms "comprising" and "having," and any variations thereof, used in the description of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include other steps or units not listed, or may optionally include other steps or units inherent to such process, method, product, or apparatus.

[0026] It should be noted that in the embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0027] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0028] In one implementation, such as Figure 1 As shown, Figure 1 A schematic diagram of a displacement detection device according to an embodiment of this application is shown. It includes an inclination sensor, a carrier, a rotating component, and a horizontal sliding component. The inclination sensor is fixed on the carrier. The first end of the carrier is rotatably connected to the rotating component. The second end of the carrier is fixedly connected to the horizontal sliding component. The rotating component is fixed on a vertical mounting wall. The horizontal sliding component is in contact with the horizontal mounting wall and can slide relative to it.

[0029] The tilt sensor is used to detect the tilt angle of the vehicle. This tilt angle can be understood as the angle between the vehicle and the vertical direction, such as... Figure 1 The included angle θ.

[0030] The rotating component is used to fix itself to a vertical mounting wall and to allow the vehicle to rotate about the rotation axis of the fixed rotating component, thereby changing the angle between the vehicle and the vertical direction. The rotating component can be any component that meets the aforementioned requirements; for example, the rotating component can be a hinge, latch, etc., which are easy to fix.

[0031] A horizontal sliding member is used so that, when displacement occurs, the second end of the carrier can change its position along with the horizontal sliding member, thereby changing the angle between the carrier and the vertical direction. The horizontal sliding member can be a flexibly rotatable spherical part, wheel-shaped part, etc.

[0032] It is understandable that the vertical mounting wall and the horizontal mounting wall are relatively movable. Since the rotating component is fixedly connected to the vertical mounting wall, when a relative displacement occurs between the vertical and horizontal mounting walls, the second end of the carrier, which is fixedly connected to the horizontal sliding component, will change the angle between the carrier and the vertical direction with the relative displacement. Therefore, the vertical displacement of the vertical mounting wall and the horizontal displacement of the horizontal mounting wall can be calculated based on the change in the aforementioned angle.

[0033] Specifically, let L be the distance from the contact point between the horizontal sliding member and the horizontal mounting wall to the center line of the rotating member's axis; let x0 be the initial distance from the contact point between the horizontal sliding member and the horizontal mounting wall to the vertical plane containing the center line of the axis of rotation; let y0 be the initial distance from the center line of the axis of rotation to the horizontal plane containing the contact point between the horizontal sliding member and the horizontal mounting wall; and let θ be the initial angle between the vehicle and the vertical direction. Then the following relationship exists:

[0034] y0=L*cosθ, x0=L*sinθ

[0035] When a relative displacement occurs between the vertically mounted wall and the horizontally mounted wall, the following relationship exists:

[0036] dy = -x0 * dθ, dx = y0 * dθ

[0037] Where dy is the vertical displacement, dx is the horizontal displacement, and dθ is the change in the angle between the vehicle and the vertical direction. The negative sign "-" indicates that the vertical displacement and the change in the angle are in opposite directions.

[0038] It is understood that the aforementioned vertical mounting wall only indicates that the local mounting position of the rotating component is approximately a vertical sidewall, and does not limit the shape, appearance, or other characteristics of the entire sidewall. For example, it is not required that the entire sidewall be flat. Similarly, the aforementioned horizontal mounting wall only indicates that the local area contacted by the horizontal sliding component is approximately horizontal and flat, and does not limit the shape, appearance, or other characteristics of the entire sidewall. For example, it is not required that other sidewalls outside the local area contacted by the horizontal sliding component are also horizontal and flat.

[0039] Understandably, a suitable carrier size can be selected based on parameters such as displacement monitoring resolution and tilt sensor resolution. For example, when the tilt sensor used has a resolution of 3°, and the required horizontal displacement monitoring resolution is no higher than 5mm, y0 can be calculated to be approximately 95mm according to dx=y0*dθ. If the initial angle θ between the carrier and the vertical direction is 45°, then the distance L from the contact point between the horizontal sliding component and the horizontal mounting wall to the center line of the rotation axis of the rotating component is approximately 134mm. Therefore, the length of the carrier can be further determined based on the specific parameters of the horizontal sliding component and the component.

[0040] Understandably, this application places an inclination sensor on a vehicle whose inclination angle changes with the relative displacement between the vertical and horizontal mounting walls. The vertical and horizontal displacements can be known simultaneously using only the change in inclination angle detected by the inclination sensor. This approach has the advantages of low cost, easy installation, and wide applicability to various scenarios.

[0041] In some cases, the entire side wall where the vertical or horizontal mounting wall is located is not flat, and there may even be situations where rotating components cannot be installed and fixed, or horizontal sliding components cannot slide freely. In such cases, the following methods can be used to solve the problem.

[0042] In yet another implementation, such as Figure 2 As shown, Figure 2 A schematic diagram of the displacement detection device according to another embodiment of this application is shown. The entire sidewall containing the vertical and horizontal mounting walls is not entirely flat. In particular, when the mounting position of the fixing member or the contact position of the horizontal sliding member is not ideal, the flatness of the mounting position or contact position can be ensured by adding appropriate components. Figure 1 Based on the corresponding embodiment, it also includes a fixed component and a sliding support component, wherein the rotating component is fixed on the fixed component, the fixed component is fixed on the vertical mounting wall; the sliding support component is fixed on the horizontal mounting wall, and the horizontal sliding component contacts the sliding support component and can slide relative to it.

[0043] Understandably, the fixed component has a relatively flat mounting surface, making it easier to fix the rotating component to a vertical mounting wall that is not entirely flat or is inconvenient to install. Similarly, the sliding support component has a relatively flat sliding contact surface, thereby ensuring the flatness of the sliding range of the horizontal sliding component and thus improving the detection accuracy. For example, the sliding support component is a groove, rail, or slide plate whose shape matches the horizontal sliding component.

[0044] Understandably, depending on the specific material and shape of the vertical mounting wall, there are various ways to fix the fixing components to the vertical mounting wall, including but not limited to screw fixing, magnetic fixing, adhesive fixing, clamp fixing, and inlay fixing. Similarly, depending on the specific material and shape of the horizontal mounting wall, there are various ways to fix the sliding support to the horizontal mounting wall, including but not limited to screw fixing, magnetic fixing, adhesive fixing, clamp fixing, and inlay fixing.

[0045] In this application, the displacement detection device can be wired, wireless, or a combination of both.

[0046] In one embodiment, the displacement detection device is wired, allowing it to be powered and transmit data via a wired connection.

[0047] In one example, the tilt sensor also includes a data transmission interface for reporting detection data to a data processing device; the aforementioned detection data includes the angle between the vehicle and the vertical direction.

[0048] In one implementation, the displacement detection device is wireless, specifically, it transmits detection data wirelessly and is powered by collecting ambient energy.

[0049] In one example, the displacement detection device wirelessly collects electromagnetic wave energy from the environment to obtain the electrical energy required for operation and transmits the detection data.

[0050] It is understood that when the displacement detection device is wireless, the displacement detection device also includes an antenna, which is used to send the detection data to the data processing device; the aforementioned detection data includes the angle data between the vehicle and the vertical direction.

[0051] In one example, the displacement detection device is powered by a battery or by collecting non-electromagnetic energy, and transmits the detection data wirelessly. The aforementioned non-electromagnetic energy includes, but is not limited to: light energy, kinetic energy, thermal energy, and fluid energy. Light energy sources include, but are not limited to: natural light and artificial lighting. Kinetic energy sources include, but are not limited to: human movement and equipment vibration. Thermal energy sources include, but are not limited to: human body temperature, waste heat from equipment, and geothermal gradients. Fluid energy includes, but is not limited to: wind, water flow, waves, and fluids in pipes.

[0052] In one example, the displacement detection device wirelessly collects electromagnetic wave energy for power supply and wirelessly transmits detection data. The sources of the aforementioned electromagnetic wave energy include, but are not limited to: downlink messages sent by the first device, Wi-Fi signals in the environment, base station signals from cellular networks, and broadcast television signals.

[0053] In one embodiment, the displacement detection device employs both wired and wireless methods.

[0054] In one example, the displacement detection device is powered and transmits data via a wired connection, and can also transmit data wirelessly when needed.

[0055] In one example, the displacement detection device is powered by a wired connection and transmits data wirelessly.

[0056] This application also provides a displacement detection system, which includes a data processing device and a displacement detection device, wherein the data processing device is configured to receive detection data reported by the displacement detection device, and obtain the vertical displacement of the vertically installed wall and / or the horizontal displacement of the horizontally installed wall based on the detection data.

[0057] It is understood that data can be transmitted between the data processing device and the displacement detection device via wired or wireless means. This application does not limit the specific connection relationship between the data processing device and the displacement detection device.

[0058] In one example, the data processing device is electrically connected to the displacement detection device, and the displacement detection device reports the detection data to the aforementioned data processing device via a wired connection.

[0059] In one example, the displacement detection device wirelessly reports the detection data to the aforementioned data processing device. Specifically, the displacement detection device includes an antenna one, and the data processing device includes an antenna two. The antenna one is configured to transmit detection data to the antenna two, and the data processing device then processes the received detection data to obtain the vertical displacement of the vertically mounted wall and / or the horizontal displacement of the horizontally mounted wall based on the detection data.

[0060] Although this application has been described herein with reference to illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, within the scope of this application, various variations and improvements can be made to the components and / or layout of the subject matter combination layout.
