Description

Technical Field

[0001] The present invention relates to the field of sensor technology, and in particular to a displacement sensor integrated monitoring device with triple protection levels. Background Art

[0002] Over the past 20 years, structural health monitoring has become a popular research topic in the field of civil engineering. Its purpose is to monitor, analyze, and identify various loads and structural responses of target structures during their service life, thereby evaluating their structural performance and safety status. Generally speaking, displacement is one of the most obvious parameters of a structure's response to internal and external loads. Monitoring the displacement changes of hydraulic structures can provide quantitative information for structural safety assessment and maintenance, and can be further converted into corresponding physical indicators for comprehensive structural health assessment. Various types of hydraulic structures face highly complex and diverse water-related environments, with multiple hidden dangers such as poor geological conditions, strong wave impact, and uneven corrosive media. It is expected that hydraulic structures will undergo potential horizontal cumulative displacements under the action of various loads, posing a threat to structural stability and even causing collapse and instability. Therefore, monitoring and predicting the displacement status of hydraulic structures is a key consideration to ensure their long-term safe operation.

[0003] With advances in sensor technology and measurement equipment, the accuracy, real-time performance, and reliability of existing displacement sensors have significantly improved. Modern intelligent monitoring sensor technology overcomes many of the shortcomings of traditional sensors and has been widely used in hydraulic structures. However, the complex environments in which hydraulic structures operate are crucial. Port projects, particularly those involving liquefied natural gas (LNG) terminals, place extremely high demands on sensor explosion-proofing. Long-term exposure to water also poses significant challenges to the sensors' waterproofing and corrosion resistance. Currently, existing sensor monitoring equipment and technologies still suffer from numerous limitations, including limited applicability, insufficient three-proof performance, imperfect automatic monitoring technology, difficulty ensuring data continuity and accuracy, low information transmission and processing efficiency, and limited portability and flexibility. Therefore, ensuring that sensors can effectively cope with harsh water-related environments while ensuring stable data acquisition and transmission signals, ensuring accurate and timely displacement monitoring, remains a key challenge. To this end, we propose an integrated intelligent displacement monitoring device and method for harsh water-related environments, aiming to overcome the shortcomings of existing technologies and enhance sensor monitoring performance in complex environments.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] See also Figure 1-14 , the present invention provides the following technical solutions:

[0041] Example 1:

[0042] A triple-proof level displacement sensor integrated monitoring device comprises a shell 2, a panel 1 is provided on the front side of the shell 2, an inner cavity is provided on the top of the shell 2, a data acquisition module and a transmission integrated submodule are provided, two explosion-proof connectors 4 are provided on the top of the shell 2, explosion-proof cables 18 are connected to the explosion-proof connectors 4, one end of the two explosion-proof cables 18 is respectively connected to an explosion-proof power supply 16 and an explosion-proof displacement meter 14, the data acquisition module and the transmission integrated submodule include a displacement sensor, a 4G wireless communication module connection and a processor, the processor is respectively connected to the displacement sensor and the wireless communication module to realize data collection and transmission functions, the shell 2 is an ultra-high performance corrosion-resistant shell, a plurality of first screws 5 are plugged into the front side of the panel 1, the panel 1 is mounted on the front side of the shell 2 through the first screws 5, and a nameplate 3 is provided on the front side of the panel 1.

[0043] A second anti-corrosion shell 17 is provided on the outside of the explosion-proof power supply 16, and the second anti-corrosion shell 17 is an integrated packaging treatment. A first anti-corrosion shell 15 is provided on the outside of the explosion-proof displacement meter 14, and the first anti-corrosion shell 15 is specially treated with a pull wire. The inner cavity of the explosion-proof displacement meter 14 is provided with a data processing submodule, and the data processing submodule is a network data middle platform based on cloud computing, which is used to automatically process, analyze and store monitoring data, and realize real-time evaluation and early warning functions of the monitoring sites. The explosion-proof displacement meter 14 is a three-proof level displacement meter with a protective shell, which is used to measure the displacement deformation of the measuring point in real time.

[0044] The front-end explosion-proof displacement meter 14 of the data sensing submodule adopts the ML-400 explosion-proof displacement meter produced by Milang Company, with a measuring range of 0~400mm. The housing of the displacement meter is processed by a special wire drawing process, and the protection level reaches the IP68 standard.

[0045] The housing 2 is made of a polytetrafluoroethylene (PTFE)-based composite material, and the surface is coated with a Teflon + TH38-31 epoxy ester self-drying low-resistance semiconductor antistatic coating to form an integrated packaging structure with three-proof levels of explosion-proof, waterproof and corrosion-resistant properties.

[0046] The data acquisition and transmission integration submodule uses a high-precision 24-bit analog-to-digital converter (ADC) to convert the sensor's analog output signal into a digital signal. A 4G wireless transmission module seamlessly connects to it, transmitting the collected displacement data in real time to the network data center. The module supports remote configuration and upgrades, ensuring stable and reliable data transmission.

[0047] The explosion-proof power supply 16 uses a 10W monocrystalline silicon solar panel as the main power supply and is equipped with a 3.7V / 10000mAh lithium battery as a backup power supply. Energy management is achieved through an intelligent charge and discharge control circuit. The solar panel is fixed to the top or side of the integrated module housing at an installation angle of 30±5° to ensure optimal lighting conditions. It is connected to the explosion-proof connector 4 of the data acquisition and transmission integrated sub-module by an explosion-proof cable 18 with a protective casing to ensure power supply reliability in harsh environments and long-term stable operation of the device.

[0048] The working principle of the above embodiment is:

[0049] First, at key locations of hydraulic structures, such as port terminal pile foundations, breakwater cladding, dam bodies, spillway side walls, gate opening and closing structures, and lock chamber walls, displacement meters are installed at appropriate locations according to monitoring needs. The displacement meters are fixed to the surface of the structure with stainless steel bolts to ensure that they change synchronously with the displacement of the monitored structure to ensure measurement accuracy. During installation, check the connection reliability and protective sealing of all interfaces.

[0050] Connect the integrated data processing integrated box to the output end of the sensor to ensure the connection reliability and protective sealing of the connecting wires and adapters. Use the acquisition device mounting bracket or fixing screw holes to directly install or add additional protective devices based on the site and machine installation space facilities. Synchronously install the integrated box adjacent to the displacement meter. The solar power module is installed on the top or side of the integrated box's protective shell to ensure that it can fully receive sunlight. The charging plate and lithium battery are connected through a dedicated charging circuit.

[0051] After the device is physically installed, the power is turned on and the device is started. After the system passes the self-test, the data acquisition and processing integrated module begins to collect the analog signal output by the displacement meter and converts it into a digital signal.

[0052] When the system is working, the data acquisition module collects displacement signals according to the preset time interval of the network monitoring center (the default setting is 1 minute), and uses the algorithm model to perform pre-processing such as filtering, compensation, and calibration on the data. The processed data is encrypted and transmitted to the cloud monitoring platform through an industrial-grade 4G module (supporting TCP / IP protocol, transmission delay <500ms) and stored in the associated server database.

[0053] It should be noted that the data processing submodule of this device primarily serves as a network monitoring platform, employing a three-tier architecture for intelligent monitoring. The real-time monitoring layer visualizes data through dynamic displacement-time curves (refresh rate 1Hz) and three-dimensional displacement field reconstruction. The early warning analysis layer implements multi-level early warning (warning / alarm / emergency alarm) based on preset displacement thresholds and displacement rate thresholds. The health assessment layer uses a time series model (prediction error ≤ 5%) to predict displacement trends and combines it with a distribution model to assess the remaining useful life of the structure. All analysis results are stored in a distributed time series database, providing a quantifiable health assessment basis for structural maintenance decisions.

[0054] The communication protocols, mechanical interface standards, and other undetailed parts adopted in the present invention all comply with current international standards and industry specifications. The casing protection level of the device reaches IP67 (GB / T 4208-2017), the intrinsically safe circuit parameters meet Ui≤12V and Ii≤1A, the maximum surface temperature does not exceed 135°C under rated working conditions, the explosion-proof structure complies with the requirements of GB / T3836.1-2021 and GB / T 3836.4-2021, is marked Ex ib ⅡB T4 Gb, and has passed the national explosion-proof certification.

[0055] Example 2:

[0056] Please refer to Figure 2-7 The bottom of the explosion-proof joint 4 is fixedly connected to the bottom plate 6, and connecting plates 7 are provided on the left and right sides of the explosion-proof joint 4. The connecting plate 7 is fixedly connected to two horizontal plates 8 on the side close to the explosion-proof joint 4. The top of the horizontal plate 8 is plugged with a second screw 9, and the bottom end of the second screw 9 passes through the bottom plate 6. The top of the horizontal plate 8 is fixedly connected to a square tube 10, and the inner cavity of the square tube 10 is movably penetrated by a connecting rod 12. The top of the square tube 10 is plugged with a third screw 11, and the connecting rod 12 is fixedly connected to a pressure plate 13 on the side close to the explosion-proof joint 4.

[0057] The working principle of the above embodiment is:

[0058] When installing the explosion-proof joint 4, move the horizontal plate 8, and the horizontal plate 8 drives the connecting plate 7 to move the top of the bottom plate 6, and then move the second screw 9. The second screw 9 passes through the horizontal plate 8 and the bottom plate 6, and tightens the second screw 9 to the top of the shell 2, thereby completing the installation of the explosion-proof joint 4, the horizontal plate 8 and the connecting plate 7. Then, after connecting the explosion-proof cable 18 to the explosion-proof joint 4, install the pressure plate 13. When installing the pressure plate 13, first move the pressure plate 13 above the explosion-proof joint 4, and the pressure plate 13 drives the connecting rod 12 to pass through the square tube 10, and then pass the third screw 11 through the top of the square tube 10, and tighten the third screw 11, thereby fixing the connecting rod 12 to the top of the connecting plate 7. At this time, the pressure plate 13 presses the explosion-proof cable 18 to the top of the explosion-proof joint 4, which can prevent the explosion-proof cable 18 from being pulled out of the explosion-proof joint 4 due to external forces, thereby ensuring the normal progress of the monitoring work.

[0059] Example 3:

[0060] Please refer to Figure 8-14 , four mounting holes 19 are provided on the shell 2, and the inner cavity of the mounting hole 19 is movably inserted with a bolt 20. Two protective covers 21 are provided on the front side of the shell 2. The two protective covers 21 are close to the left and right sides of the shell 2. The protective covers 21 match with the bolts 20. The rear side of the protective cover 21 fits with the front side of the shell 2. The front side of the protective cover 21 is fixedly connected to the limit rod 22. The left and right sides of the shell 2 are fixedly connected with a fixing plate 23. A limit slot 24 is provided on the fixing plate 23. The limit rod 22 movably passes through the limit slot 24. A first slot 26 is provided on the side of the limit rod 22 away from the shell 2, and two second slots 27 are provided on the side of the fixing plate 23 away from the shell 2. A rod 25 is movably passed through the inner cavity of the first slot 26. The rod 25 is fixedly connected to the adjacent connecting plate 7. The cross section of the rod 25 is L-shaped. The rod 25 movably passes through the two second slots 27, and the rod 25 matches the first slot 26 and the second slot 27 respectively.

[0061] The working principle of the above embodiment is:

[0062] When installing the shell 2, first move the protective cover 21 forward, and the protective cover 21 drives the limiting rod 22 to move in the inner cavity of the limiting groove 24. The protective cover 21 moves forward to the rear side of the fixing plate 23. At this time, the mounting hole 19 is exposed, and then the bolt 20 cooperates with the mounting hole 19 to fix the shell 2 in the installation position, and then move the protective cover 21 backward. The protective cover 21 moves backward until the shell 2 fits together. At this time, the protective cover 21 wraps and hides the two bolts 20, and then installs the connecting plate 7 of the second embodiment. The connecting plate 7 drives the insertion rod 25 to pass through the first slot 26 and the two second slots 27, and then fixes the limit rod 22 and the protective cover 21, that is, the device fixes the protective cover 21 through the connecting plate 7 and the insertion rod 25, and the connecting plate 7 is used to fix the explosion-proof cable 18, so when the outer shell 2 needs to be removed, the connecting plate 7 needs to be removed, and then the explosion-proof cable 18 needs to be removed, so as to avoid the explosion-proof cable 18 not being removed when the outer shell 2 is removed, avoiding unnecessary safety hazards, and forcing the staff to remove the outer shell 2 according to regular operations.
