Description

Technical Field

[0001] This invention relates to the field of data acquisition technology, specifically to a multifunctional data acquisition device and system for optical cable junction boxes. Background Technology

[0002] As a critical node in optical communication networks, the internal environment of fiber optic splice closures directly affects the security and stability of fiber optic links. To achieve intelligent monitoring of fiber optic splice closures, current technologies typically employ a solution of adding an independent data acquisition module within a traditional splice closure.

[0003] Patent publication number CN112068265B relates to the field of data collection device technology, including a box cover and a box bottom connected to the box cover. The box cover and box bottom are integrally injection molded, with a connecting edge injection molded between them. The connecting edge is strip-shaped, and the strip structure is composed of multiple sheet-like fixing pieces. The fixing pieces include a first fixing piece and a second fixing piece arranged in an alternating strip pattern. By using injection molding to integrally mold the box cover and box bottom, and simultaneously injection molding the connecting edge between them to achieve overall connection, not only are process steps saved, but the sealing connection between the two is also of a high level. Furthermore, the use of alternating strip-shaped fixing pieces to form the connecting edge provides an alternating positioning and cushioning effect during bending.

[0004] The aforementioned patent features an interlaced structure that provides staggered positioning and cushioning against bending. Traditional data acquisition devices deployed within fiber optic junction boxes, while capable of monitoring basic parameters such as ambient temperature, humidity, and vibration, generally suffer from severe environmental adaptability deficiencies. These devices often lack effective self-sealing designs or rely on simple static seals, leaving their core sensors and circuit boards directly exposed to the harsh conditions of the junction box—humid, dusty, and potentially corrosive—for extended periods. Under prolonged operation, continuous intrusion of external moisture and dust can easily cause sensor malfunction due to moisture, electrolytic corrosion of the circuit boards, or overheating from dust accumulation. This not only leads to data drift and inaccuracies but also triggers frequent false alarms, severely interfering with maintenance decisions. More importantly, this aging and damage to internal components caused by environmental corrosion significantly shortens the device's lifespan, forcing maintenance personnel to frequently open and replace components, increasing maintenance costs and workload.

[0013] Secondly, a multifunctional data acquisition system for optical cable junction boxes is provided, the multifunctional data acquisition system including the aforementioned multifunctional data acquisition device, and further including: Data scheduling unit: Receives physical information data uploaded by vibration sensors, temperature sensors and air pressure sensors, processes, stores and transmits the physical information data; Communication power supply unit: used for near-field communication data reading with external barcode scanning devices and for collecting energy to provide power.

[0014] Furthermore, the data scheduling unit includes: a data processing module and a data storage module; The data processing module: after receiving the physical information data, performs filtering, calibration and unit conversion on the physical information data to obtain physical accuracy data; The data storage module stores physical precision data in the internal flash memory.

[0015] Furthermore, the data processing module, upon receiving the physical information data, filters, calibrates, and converts the physical information data to obtain physical accuracy data. The specific steps are as follows: The three types of physical information data are aligned to construct a spatiotemporal vector to obtain a multidimensional vector sequence. The root mean square is calculated based on the multidimensional vector sequence, and the filtering parameters are adaptively adjusted. The similarity weights are calculated, and a weighted average filter is used to denoise the multidimensional vector sequence, resulting in a filtered vector sequence, the expression of which is:

[0016] In the formula: For similarity weights, It is a multidimensional vector sequence; Based on the filter vector sequence, cross compensation, coupling calibration, and zero-point calibration are performed to obtain physical accuracy data. The formulas for cross-compensation and coupling calibration are as follows:

[0017] In the formula: For reference temperature, This is the filtered temperature value;

[0018] In the formula: These are the coupling empirical coefficients. This represents the peak vibration time.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In this invention, the placement box is sealed by sealing plate one and sealing plate two, which can effectively seal and isolate the direct intrusion of external moisture, dust and corrosive gases. This can prevent the sensor from short-circuiting due to moisture, the circuit board from corroding or the thermal effect caused by dust accumulation, thereby ensuring the long-term accuracy and stability of monitoring data, avoiding false alarms or data drift caused by environmental interference. The dry and clean internal space formed by the seal provides an ideal working environment for electronic components, greatly reducing the risk of insulation degradation or electrolytic corrosion caused by moisture, significantly extending the service life and reliability of the battery and electronic components in the acquisition box, and reducing the frequency of maintenance and replacement.

[0020] 2. In this invention, the two key steps of sealing and rigidly fixing the data collection box can be completed automatically and sequentially by closing the cover plate. The operation process is simple and avoids the omissions or uneven torque that may occur when sealing and tightening are performed manually. The tight fixing of the data collection box can effectively resist vibration and impact from different directions and prevent any slight displacement or loosening of the data collection box inside the box. It provides an extremely stable installation benchmark for the internal precision sensors, thereby ensuring the accuracy and consistency of the monitoring data.

[0021] 3. In this invention, the cable is clamped by the coordinated action of the sliding outer plate and the inner clamp, forming a strain relief mechanism. This mechanism can effectively absorb the tensile, swaying, or vibration stress that the cable may be subjected to externally, preventing these stresses from being directly transmitted to the fragile solder joints or connectors connecting the cable and the circuit board. This significantly reduces the risk of interface loosening, wire breakage, or poor contact caused by cable stress, ensuring the long-term stability of signal transmission and power supply. The rewinding wheel automatically and neatly rewinds the excess cable length under the drive of the torsion spring, completely eliminating messy cable coiling. This maximizes the use of internal space and reduces potential sources of electromagnetic coupling interference, creating a cleaner working environment for electronic circuits.

[0022] 4. This invention avoids the high frequency of battery replacement and maintenance costs associated with traditional batteries by harvesting energy, thus improving the long-term economic efficiency. It can quickly read data on-site, greatly facilitating daily operation and maintenance and troubleshooting, and reducing the time and cost of manual intervention. In addition, by integrating multiple environmental parameters such as temperature, air pressure, and vibration, it improves robustness, real-time performance, and environmental adaptability. It has strong scalability and can be deployed in application scenarios of different scales. Attached Figure Description

The data acquisition box 3 serves as a device to house the vibration sensor, temperature sensor, and barometric pressure sensor. This application does not impose specific limitations on its structure. In this embodiment, it is as follows... Figure 2 As stated above.

A fixing device for enhancing the fixing effect of the collection box 3 is installed on the inner wall of the placement box 1; A winding device for winding excessively long cables into the placement box 1 is installed on the inner wall of the placement box 1.

[0029] The sealing device includes a sliding plate 8, a first connecting rod 9, a sliding plate 10, a second connecting rod 11, a sliding rod 12, a first sealing plate 13, and a third connecting rod 14. The sliding plate 8 is slidably installed on the surface of the cover plate 2 near the handle 4. One end of the first connecting rod 9 is rotatably connected to the handle 4, and the other end of the first connecting rod 9 is rotatably connected to the sliding plate 8.

One end of the third connecting rod 14 is rotatably connected to the sliding rod 12, and the other end of the third connecting rod 14 is rotatably connected to the sliding plate 10.

[0030] An elastic element is provided between the sliding rod 5 and the handle 4. The elastic element is provided to drive the sliding rod 5 to reset. An elastic element is provided between the fixing plate 7 and the sealing plate 15. The elastic element is provided to move the fixing plate 7 upward. A sealing groove is provided on the side of the placement box 1 near the sealing plate 13. The sealing plate 13 contacts the inner wall of the sealing groove.

[0031] In this embodiment, during operation: When using the acquisition box 3 to detect external objects, the acquisition box 3 needs to be placed inside the placement box 1. When placing the acquisition box 3 inside the placement box 1, the cover plate 2 needs to be rotated to release the seal of the placement box 1. While rotating the cover plate 2, the handle 4 needs to be gripped. Gripping the handle 4 will pull the sliding rod 5 upwards. The upward movement of the sliding rod 5 will cause the pressure rod 6 to move upwards. When the pressure rod 6 moves upwards, it will release the pressure on the second sealing plate 15, causing the second sealing plate 15 to move upwards. The upward movement of the second sealing plate 15 will release its contact with the first sealing groove, and the pressure rod 6 will move upwards. The movement of the lever 16 will cause the locking button 16 to move, which will release the grip 4 from its fixation, allowing the grip 4 to move towards the sliding plate 10. The movement of the grip 4 will push the first linkage 9 to move, which in turn will push the sliding plate 8 to move. The movement of the sliding plate 8 will push the second linkage 11 to move, which will push the sliding plate 10 to move away from the sliding rod 12. The movement of the sliding plate 10 will pull the third linkage 14 to move, which in turn will pull the sliding rod 12 to move. The movement of the sliding rod 12 will cause the sealing plate 13 to move towards the inside of the cover plate 2. Sealing plate 13 will release the seal between the placement box 1 and the cover plate 2. After sealing plate 13 moves into the cover plate 2, the handle 4 can be pulled upwards to release the obstruction of the placement box 1. After the collection box 3 is placed, the cover plate 2 is closed, and the handle 4 is pulled to reset it. After the handle 4 is reset, sealing plate 25 and sealing plate 13 will re-contact the inner walls of sealing groove 1 and sealing groove 2. Then, sealing plate 25 and sealing plate 13 will seal the inside of the placement box 1, keeping the area around the collection box 3 dry. The sealing plate 13 and sealing plate 25 seal the placement box 1 and the cover plate 2. The seal effectively isolates the sensor from direct intrusion of external moisture, dust, and corrosive gases. This prevents the sensor from short-circuiting due to moisture or thermal effects caused by dust accumulation, thus ensuring the long-term accuracy and stability of monitoring data. It also avoids false alarms or data drift caused by environmental interference. The dry and clean internal space created by the seal provides an ideal working environment for electronic components, greatly reducing the risks of insulation degradation, mold growth, and electrolytic corrosion caused by moisture. This significantly extends the service life and reliability of the battery and electronic components in the acquisition box 3, and reduces the frequency of maintenance and replacement.

[0032] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the multifunctional data acquisition device for optical cable junction boxes further includes a fixing device and a winding device.

[0034] An elastic element three is provided between the pressure plate 21 and the rebound plate 23.

[0035] The winding device includes a sliding outer plate 31, a connecting rod 32, a sliding plate 33, a push rod 34, an inner clamp 35, a pressing rod 36, a limiting rod 37, and a winding wheel 38. The sliding outer plate 31 is slidably mounted on the inner wall of the outer frame 26, and the sliding outer plate 31 is divided into an upper outer plate and a lower outer plate. The inner clamp 35 is slidably mounted on the inner wall of the sliding outer plate 31. The sliding plate 33 is slidably mounted on the inner wall of the pressing rod 36. One end of the connecting rod 32 is rotatably connected to the sliding plate 33. The other end is fixedly connected to the sliding outer plate 31. The push rod 34 is slidably installed on the inner wall of the outer frame 26. The push rod 34 is fixedly connected to the sliding outer plate 31. The take-up wheel 38 is rotatably installed on the bottom of the inner wall of the placement box 1. The pressing rod 36 is fixedly installed on the side of the sliding outer plate 31 near the take-up wheel 38. The limiting rod 37 is slidably installed on the bottom of the inner wall of the placement box 1. The take-up wheel 38 has a slot on the side near the limiting rod 37. The shape of the limiting rod 37 matches the slot.

[0036] An elastic element six is ​​provided between the inner clamp 35 and the sliding outer plate 31. The side of the limiting rod 37 near the pressing rod 36 is set as an inclined surface. An elastic element seven is provided between the limiting rod 37 and the placement box 1. A torsion spring is provided between the winding wheel 38 and the placement box 1.

[0037] In this embodiment, during operation: when the slide rod 12 pushes the sealing plate 13 into the sealing groove 2, the movement of the slide rod 12 will drive the connecting rod 22 to move. The movement of the connecting rod 22 will push the pressure plate 21 to move downward. The downward movement of the pressure plate 21 will drive the rebound plate 23 to move. The rebound plate 23 will contact the surface of the collection box 3. When the sealing plate 13 contacts the inside of the sealing groove 2, the rebound plate 23 will press the collection box 3 tightly. When the collection box 3 contacts the bottom of the inner wall of the placement box 1, it will contact the inclined surface of the clamping block 28. When the collection box 3 pushes the clamping block 28 to move, it will press the elastic element 5 to contract and store force. The reaction force applied by the elastic element 5 to the clamping block 28 will push the clamping block 28 to clamp the collection box 3. When the slide rod 12 moves, it will push the connecting rod 24 to move. The movement of the connecting rod 24 will push the pressure block 25 to move downward. The downward movement of the pressure block 25 will press the pressing block 27 to move downward. The downward movement pushes the slider 291 downward, and the movement of the clamping block 28 drives the positioning plate 29 to move. The movement of the positioning plate 29 drives the circular groove to move. When the slider 291 moves downward, it inserts into the circular groove. When the slider 291 is inserted into the circular groove, it fixes the positioning plate 29. When the positioning plate 29 is fixed, it fixes the clamping block 28, making the fixation of the clamping block 28 on the acquisition box 3 more reliable. By closing the cover plate 2, the two key steps of sealing and rigid fixation of the acquisition box 3 can be completed automatically and sequentially. The operation process is simple and avoids the omissions or uneven torque problems that may occur when sealing and tightening are performed manually. The tight fixation of 3 can effectively resist vibration and impact from different directions and prevent any slight displacement or loosening of the acquisition box in the box. It provides an extremely stable installation benchmark for the internal precision sensor, thereby ensuring the accuracy and consistency of the monitoring data.

[0038] When the pressing block 27 moves downward, it drives the push rod 34 downward. The downward movement of the push rod 34 causes the sliding outer plate 31 to move towards the cable. The movement of the sliding outer plate 31 pushes the connecting rod 32 to move. The movement of the connecting rod 32 pushes the slide plate 33 to move away from the cable. The movement of the slide plate 33 pushes the inner clamp 35 towards the cable, thus clamping the cable between the sliding outer plate 31 and the inner clamp 35. When the inner clamp 35 moves upward, it drives the pressing rod 36 to move. The movement of the pressing rod 36 releases the pressure on the limiting rod 37, causing the limiting rod 37 to move away from the take-up wheel 38. The movement of the limiting rod 37 releases the limitation on the take-up wheel 38, allowing the take-up wheel 38 to rotate under the influence of the torsion spring. The rotation of the take-up wheel 38 pulls the outer plate 31 towards the cable. Excess cable moves into the placement box 1 and is stored inside. The cable is clamped by the coordinated action of the sliding outer plate 31 and the inner clamp 35, forming a strain relief mechanism. This effectively absorbs the tensile, swaying, or vibration stress that the cable may be subjected to externally, preventing these stresses from being directly transmitted to the fragile solder joints or connectors connecting the cable and the circuit board. This significantly reduces the risk of interface loosening, wire breakage, or poor contact caused by cable stress, ensuring the long-term stability of signal transmission and power supply. The rewinding wheel 38 automatically and neatly rewinds the excess length under the drive of the torsion spring, completely eliminating messy cable coiling. This maximizes the use of internal space and reduces potential sources of electromagnetic coupling interference, creating a cleaner working environment for electronic circuits.

[0039] Example 2: Based on the same inventive concept, such as Figure 9 and Figure 10 As shown, this embodiment discloses a multifunctional data acquisition system for optical cable junction boxes. For details not covered in this embodiment, please refer to the relevant sections of Embodiment 1. The multifunctional data acquisition system includes the aforementioned multifunctional data acquisition device, and further includes: Data scheduling unit: Receives physical information data uploaded by vibration sensors, temperature sensors and air pressure sensors, processes, stores and transmits the physical information data; Communication power supply unit: used for near-field communication data reading with external barcode scanning devices and for collecting energy to provide power.

[0040] It should be noted that energy harvesting for power generation can be achieved by inputting energy through photovoltaic panels or NFC coils and outputting a stable voltage for power supply. Energy storage capacitors or supercapacitors need to be designed to cope with energy fluctuations.

[0041] Among them, a dynamic power management strategy is designed, which prioritizes charging the energy storage capacitor when photovoltaic energy is sufficient; when NFC energy coupling occurs, the system is briefly activated to transmit data, and enters sleep mode when no data is collected, and is woken up by NFC.

[0042] It should be noted that the temperature and humidity sensor is used to measure the ambient temperature and relative humidity; the vibration sensor is used to detect vibration at the fiber optic cable joint to determine if there is any abnormal activity (such as construction, earthquakes, etc.); and the barometric pressure sensor is used to measure changes in the pressure of the surrounding air, which, combined with temperature data, can be used to estimate changes in altitude.

[0043] Meanwhile, in this embodiment, the sensor uses a flexible PCB and is encapsulated inside the junction box wall. It is sealed with epoxy resin or injection molding process and has IP67 / IP68 protection performance, making it suitable for long-term field deployment.

[0044] In addition, gas concentration sensors can be added to detect the concentration of specific gases, such as carbon dioxide and ammonia; and periodic data acquisition is adopted, that is, data is read from each sensor at regular intervals, and the sampling frequency is dynamically adjusted according to environmental conditions. For example, the sampling frequency is increased under high temperature or high pressure environments, while the frequency is reduced under normal conditions to save energy.

[0045] Furthermore, the data scheduling unit includes: a data processing module and a data storage module; The data processing module: after receiving the physical information data, performs filtering, calibration and unit conversion on the physical information data to obtain physical accuracy data; The data processing module, upon receiving the physical information data, performs filtering, calibration, and unit conversion on the physical information data to obtain physical accuracy data. The specific steps are as follows: The three types of physical information data are aligned to construct a spatiotemporal vector to obtain a multidimensional vector sequence. The root mean square is calculated based on the multidimensional vector sequence, and the filtering parameters are adaptively adjusted. The three types of physical information data are aligned to construct a spatiotemporal vector, resulting in a multidimensional vector sequence. Specifically, this is achieved through hardware-level triggering, aligning the data from the three sensors to microsecond-level precision. For example, using the high-frequency sampling of the vibration sensor as a reference, the data is aligned to a 1kHz timestamp using interpolation. The resulting multidimensional vector sequence is as follows:

[0046] In the formula: It is a triaxial vibration acceleration. For temperature, It refers to air pressure; The adjustment logic for adaptively adjusting filter parameters is as follows: If the root mean square is greater than the threshold, then the search window... High-frequency noise is suppressed by using a large window, while the similarity window is... To preserve vibration details, otherwise,

[0047] In this embodiment, the threshold value is 0.5, which refers to the vibration limit values ​​for different equipment types specified in standards such as GB / T 2423.10-2019 Environmental Testing Part 2: Vibration Testing.

[0048] The filtering strength is dynamically determined by the noise level. The standard deviation of the vector sequence is calculated, and the filtering strength is equal to 0.3 times the standard deviation.

[0049] The similarity weights are calculated, and a weighted average filter is used to denoise the multidimensional vector sequence, resulting in a filtered vector sequence, the expression of which is:

[0050] In the formula: For similarity weights, It is a multidimensional vector sequence; It should be noted that the calculation steps for similarity weights are as follows: For each time point t, a similarity window is extracted. In the search window Within, calculate other candidates. The Mahalanobis distance, i.e.:

[0051] In the formula: Let be the similarity window vectors for times t and m, and let Σ represent the covariance matrix of the multidimensional vector.

[0052] The similarity weight formula is:

[0053] Where: h is the filter strength parameter; Based on the filter vector sequence, cross compensation, coupling calibration, and zero-point calibration are performed to obtain physical accuracy data. Among them, the cross-compensation formula for temperature versus pressure can be derived from the ideal gas law PV=nRT, while the coupled calibration utilizes the physical correlation between vibration events and temperature changes: detecting vibration peak values ​​and recording the peak time. Within a 100ms window after the peak, the temperature data is linearly extrapolated to correct the instantaneous temperature reading deviation caused by vibration.

[0054] Therefore, the formulas for cross-compensation and coupling calibration are as follows:

[0055] In the formula: For reference temperature, the value is taken as 25℃. This is the filtered temperature value;

[0056] In the formula: This is the coupling empirical coefficient, with a value of 0.1℃ / ms, determined by laboratory calibration. This represents the peak vibration time.

[0057] The data storage module stores physical precision data in the internal flash memory. Before storage, a lightweight compression algorithm is used to reduce the number of FRAM writes and extend the storage life.

[0058] Its application in underground pipelines allows for the assessment of pipeline stability and safety through data such as temperature, humidity, air pressure, and vibration; tunnel monitoring focuses on potential problems such as harmful gas leaks and insufficient lighting to ensure safe tunnel operation; and in harsh climate areas, especially during heavy rain, blizzards, or high temperatures, the damage to fiber optic cable joints requires special attention to ensure the normal operation of communication facilities.

[0059] The device is normally in a deep sleep state with extremely low power consumption. After being activated by bringing an NFC reader close, the sensor collects data and uploads it to an external device. The vibration sensor has an interrupt trigger function, which can wake up the system to perform data collection and recording tasks when abnormal external vibrations are detected.
