Technical Field

[0001] The present invention relates to the technical field of deformation monitoring, and in particular to a deformation monitoring device and a use method thereof. Background Art

[0002] In water conservancy and hydropower projects, bridge construction, tunnel excavation and other large-scale civil engineering projects, structural safety and health monitoring is an important part of ensuring project quality and operational safety. Traditional deformation monitoring methods mainly rely on various types of sensors, such as strain gauges, displacement gauges, inclinometers, etc. These sensors usually transmit the collected information to the central monitoring system through wired or wireless data links such as cables, optical cables or radio waves. However, in actual application, due to the complex and changeable environment of the construction site, such as high temperature, high humidity, strong electromagnetic interference and other factors, traditional sensors and their data transmission links are prone to damage, signal attenuation and other problems, resulting in the inability to accurately and timely transmit data, thus affecting the monitoring effect.

[0003] In addition, large-scale engineering projects have a long construction period and involve multiple stages, including but not limited to excavation, support, pouring, lining, installation of electromechanical equipment, etc. Each stage may cause physical damage to the installed sensors, further increasing the difficulty of data collection and transmission. Therefore, how to accurately capture the tiny deformation of the monitored object has become a technical problem that needs to be solved urgently. Summary of the invention

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1

[0030] Reference Figure 1-2 , which is the first embodiment of the present invention, provides a deformation monitoring device, including a first sensor unit 100, which is arranged at a position to be monitored; a second sensor unit, which is arranged at a central monitoring station far away from the first sensor unit 100; wherein the change information of the environment in which the first sensor unit 100 is located is indirectly obtained by detecting the state change of the measuring unit 103 in the second sensor unit.

[0031] In this embodiment, the first sensor unit 100 is a component installed at a specific location that needs to be monitored, which can capture slight changes in the structure. The second sensor unit is located at a monitoring station far away from the first sensor unit 100. The main purpose of this design is to ensure the security of the data processing center and the centralized management of data. The second sensor unit is responsible for receiving data from the first sensor unit 100, and processing, storing and analyzing it. In practical applications, data transmission can be achieved through wired or wireless means. Common wireless communication technologies include GPRS, LoRa, Wi-Fi, etc., while wired communication may use optical fiber or cable connections.

[0032] The working principle of this deformation monitoring device is to utilize the signal transmission theory in physics. When the monitored object is deformed, the first sensor unit 100 will detect this change and convert the change information into an electrical signal or other form of signal. Subsequently, these signals are sent to the second sensor unit through a preset data transmission channel. After receiving the signal, the second sensor unit analyzes the change of the signal through a built-in algorithm, thereby indirectly obtaining the state change information of the environment in which the first sensor unit 100 is located. For example, if the displacement of a bridge is monitored, then when the bridge body is displaced due to heavy load or natural disasters, the first sensor unit 100 will immediately transmit this change in the form of a signal to the second sensor unit, which will then determine whether the bridge body is safe based on the received information.

[0033] Example 2

[0034] Reference Figure 1-3 , which is the second embodiment of the present invention, and provides a deformation monitoring device. The first sensor unit 100 includes an inner cylinder 102, which slides as the monitored object deforms; an outer cylinder 104, which is provided with a unidirectional compression locking tongue type tooth array 105, the interval of the locking tongue type tooth array 105 matches the interval of the measuring unit 103, and the first end of the outer cylinder 104 is provided with a knife switch 106; when the inner cylinder 102 is pulled out relative to the outer cylinder 104, each time it slides over a locking tongue type tooth array 105, it will trigger a wire 202 of a measuring unit 103 to be cut off by the knife switch 106, causing the measuring unit 103 to lose power, thereby changing its state, and generating corresponding reading changes at the remote observation station; the continuous deformation of the monitored object will cause the inner cylinder 102 to continue to slide, thereby cutting off more wires 202, and the observation station will continue to record this process until the deformation stops.

[0035] In this embodiment, an array of measuring units 103 is installed inside the inner cylinder 102, which are evenly distributed along the length direction of the inner cylinder 102. The design of the inner cylinder 102 allows it to slide freely as the monitored object (such as soil, rock or concrete structure) deforms, so as to accurately capture the deformation information. The outer cylinder 104 provides protection and support for the inner cylinder 102. It is provided with an array of unidirectionally compressed locking tongue teeth 105, which correspond to the positions of the measuring units 103 on the inner cylinder 102, ensuring that whenever the inner cylinder 102 is displaced, the corresponding measuring unit 103 will be disabled. In addition, a knife switch 106 is installed at one end of the outer cylinder 104, which is a component for disconnecting the signal transmission.

[0036] The knife switch 106 is located at one end of the outer cylinder 104. When the inner cylinder 102 is pulled outward, it will touch and activate the knife switch 106, cutting off the wire 202 of the measuring unit 103 connected to it. In this way, it is possible to accurately determine which measuring units 103 have failed due to the displacement of the inner cylinder 102, and then calculate the degree of deformation of the monitored object. Observation station: Receives signals from each measuring unit 103 and determines the state of the monitored object based on the changes in the signals. Once the signal of a measuring unit 103 is interrupted, it indicates that the corresponding position of the monitored object has been deformed.

[0037] In yet another embodiment, the monitoring end is also designed with a press-in structure suitable for compressive deformation monitoring. The first sensor unit 100 and the second sensor unit reverse the arrangement of the one-way teeth 107 of the inner cylinder 102 and the locking tongue type teeth 105 array of the outer cylinder 104, so that when the monitored object is subjected to a compressive force, the inner cylinder 102 can be pressed into the outer cylinder 104 one by one, thereby also being able to achieve accurate monitoring of the compressive deformation.

[0038] When the monitored object is stretched and deformed, the inner cylinder 102 will slide inward with the deformation of the object. The array of measuring units 103 on the inner cylinder 102 matches the interval of the array of locking tongue teeth 105 in the outer cylinder 104. Every time the inner cylinder 102 slides over an array of locking tongue teeth 105, an action is triggered. A knife switch 106 is provided at the first end of the outer cylinder 104. When the inner cylinder 102 slides, one tooth in the array of locking tongue teeth 105 will trigger the knife switch 106, causing the wire 202 of a measuring unit 103 to be cut off. After the wire 202 is cut off, the corresponding measuring unit 103 loses power supply and its state changes. This change in state will be captured by the remote observation station, resulting in corresponding changes in readings. As the monitored object continues to deform, the inner cylinder 102 will continue to slide, more wires 202 will be cut off, and the observation station will continue to record these changes until the deformation stops.

[0039] By reversing the arrangement of the one-way teeth 107 of the inner cylinder 102 and the array of the locking tongue teeth 105 of the outer cylinder 104, when the monitored object is subjected to a compressive force, the inner cylinder 102 can be pressed into the outer cylinder 104 one by one. This design ensures that the device can effectively monitor and record the deformation process regardless of whether it is tensile or compressive deformation.

[0040] Example 3

[0041] Reference Figure 1-3, which is the third embodiment of the present invention, provides a deformation monitoring device, each measuring unit 103 is formed by connecting an entanglement storage unit 200 and a power holding unit 201 through a wire 202. The measuring units 103 are arranged along the axial direction of the sensor to form a linear array of 100 to 1000 measuring units 103, and the spacing between adjacent measuring units 103 is fixed to 0.1 to 1 mm. The first sensor unit 100 is equipped with a built-in battery 203. A one-way tooth 107 is provided at the first end of the inner cylinder 102, and a first anchor plate 108 is provided at the second end of the inner cylinder 102. A second anchor plate 109 is provided at the second end of the outer cylinder 104. The one-way tooth 107 realizes a one-way sliding connection between the inner cylinder 102 and the outer cylinder 104 to prevent the inner cylinder 102 from sliding in the opposite direction. This design enables the device to accurately measure tiny changes, such as displacement, deformation, etc., over a long distance. When the inner cylinder 102 is pulled outward, it touches and activates the knife switch 106, cutting off the wire 202 of the connected measuring unit 103. In this way, it is possible to accurately determine which measuring units 103 have failed due to the displacement of the inner cylinder 102, and then infer the degree of deformation of the monitored object.

[0042] In this embodiment, the entanglement storage unit 200 is a technology that uses quantum entanglement characteristics to achieve data storage. The "entanglement" here does not refer to real quantum entanglement, but refers to a highly accurate data association or synchronization mechanism to ensure that the data exchange and synchronization between the two sensor units can achieve extremely high accuracy. Each measurement unit 103 is composed of an entanglement storage unit 200 and a power holding unit 201, which are connected by a wire 202 to form a linear array arranged along the sensor axis.

[0043] Specifically, the "entanglement storage unit 200" in each measurement unit 103 is actually a highly precise data storage module. These modules ensure that the data between the two sensor units can be closely associated through a certain algorithm or protocol. When a sensor unit detects a change in a parameter, the change will be recorded and transmitted to the other sensor unit via a high-speed communication link.

[0044] In order to achieve data synchronization, each sensor unit has a clock synchronization module inside. These clock synchronization modules are regularly calibrated through the network or dedicated communication lines to ensure that the time reference of all sensor units is consistent. Through this time synchronization mechanism, it can be ensured that the data collected by each measurement unit 103 at the same time point is synchronized, thereby avoiding errors caused by time differences.

[0045] Once the power supply of a certain measuring unit 103 is cut off, the unit will stop working and no longer send data. The system can determine the displacement of the inner cylinder 102 by detecting which units have stopped working, and then calculate the deformation degree of the monitored object. Through highly accurate data association and synchronization mechanism, the consistency and accuracy of the data are ensured, which is particularly suitable for occasions requiring high-precision measurement.

[0046] The one-way teeth 107 between the inner cylinder 102 and the outer cylinder 104 allow the inner cylinder 102 to move outward under the action of external force, but prevent it from sliding in the opposite direction. This feature is very useful for monitoring processes that only change in one direction, such as surface displacement in earthquakes, and can effectively record the maximum displacement without losing data due to subsequent rebound.

[0047] A method for using a deformation monitoring device, in the absence of external force, the inner cylinder 102 is in a preset position in the outer cylinder 104. At this time, all measuring units 103 are working normally and continuously sending signals to the observation station. When the monitored object (such as soil, rock or concrete structure) is deformed, this deformation will cause the inner cylinder 102 to move relative to the outer cylinder 104. Since the inner cylinder 102 is designed to slide freely as the monitored object deforms, it can accurately reflect the deformation of the monitored object. As the inner cylinder 102 moves, the measuring units 103 on the inner cylinder 102 will contact the locking tongue teeth 105 in the outer cylinder 104 in turn. Whenever a measuring unit 103 contacts the teeth, the measuring unit 103 will be physically "failed" - that is, disconnected from the power supply. This process is achieved by a knife switch 106 located at one end of the outer cylinder 104.

[0048] The observation station continuously receives signals from each measuring unit 103. Once a measuring unit 103 is "failed" due to the displacement of the inner tube 102, the observation station will detect the interruption of the signal of the unit. By analyzing which measuring units 103 signals have been interrupted, the specific displacement and direction of the inner tube 102 can be determined, so as to deduce the degree of deformation of the monitored object at the corresponding position. Based on the received data, the observation station can evaluate the overall health of the monitored object and promptly identify potential safety hazards. For example, in the field of civil engineering, this device can help engineers monitor the stability of infrastructure such as bridges, tunnels, and dams in real time, which is of great significance for disaster prevention.
