Abstract
Description
Technical Field
[0001] This application relates to the field of power communication technology, and in particular to an optical cable junction box and a power communication system. Background Technology
[0002] Optical fiber cables are a core infrastructure for power system communication, integrating transmission lines, lightning protection grounding wires, and communication optical cables into a single unit, and are widely used in high-voltage transmission lines. Optical fiber splice closures are used to achieve mechanical connection between two adjacent optical cables and to protect fiber optic splices, ensuring the continuous and stable mechanical strength and optical performance of the transmission line. Optical fiber splice closures must not only withstand the harsh outdoor environment but also protect the internal optical fibers from moisture, dust, vibration, and other factors, making them one of the most prone-to-fault nodes in transmission line systems.
[0003] Currently, the optical fiber itself is typically used as the sensing medium. A monitoring system monitors parameters such as fiber loss, breakpoints, temperature, and strain stress to assess the condition of the fiber optic splice closure. However, monitoring the fiber optic cable splice closure via the cable itself is susceptible to misjudgments due to factors such as overall power line stress and environmental interference. This makes it difficult to accurately reflect the actual condition of the splice closure and reduces detection precision. Utility Model Content

The optical fiber fusion splice tray is used to fix and fusion multiple optical cables. The camera module is used to photograph the optical fiber fusion splice tray. The main control module is electrically connected to the camera module.

[0015] The optical fiber splice box of this application incorporates a camera module, tilt sensor, temperature sensor, and humidity sensor within the splice box body.

[0021] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of an optical cable junction box provided in one embodiment of this application. Figure 2 This is a functional block diagram of a power communication system provided in one embodiment of this application. The optical cable junction box 100 includes a junction box body 10, a main control module 21, and a camera module 22. The main control module 21 and the camera module 22 are located in the junction box body 10, and the main control module 21 and the camera module 22 are electrically connected.
[0022] The junction box body 10 includes a housing 11 and an optical fiber fusion splice tray 12. The housing 11 has a receiving cavity 110, and the optical fiber fusion splice tray 12 is disposed within the receiving cavity 110. The housing 11 has multiple optical cable holes (not shown), which communicate with the receiving cavity 110. The optical cable holes are used for passing optical cables (not shown). The optical fiber fusion splice tray 12 is used to fix the spliced optical cables. Specifically, multiple optical cables are respectively passed through multiple optical cable holes, and the optical fibers in each optical cable are spliced together by the optical fiber fusion splice tray 12, thereby achieving continuous transmission between the optical cables.
[0023] Please see Figure 1The outer casing 11 includes a base 112 and a cover 113 connected to the base 112. The base 112 is located on one side of the cover 113 in the height direction H of the outer casing 11. The cover 113 and the base 112 together form a receiving cavity 110. The cover 113 can be sealed to the base 112 by a sealing element (not shown) to improve the sealing performance of the junction box body 10 and reduce the risk of moisture interference inside the outer casing 11. The sealing element can be, but is not limited to, a sealing ring, adhesive, etc.
[0024] In some embodiments, the optical cable hole is located on the base 112. In another embodiment, the optical cable hole is located on the cover 113, or on both the base 112 and the cover 113.
[0025] In some embodiments, the junction box body 10 includes a plurality of optical cable inlet adapters 13, which are respectively inserted into a plurality of optical cable holes. The optical cable inlet adapters 13 are used for inserting optical cables and can fix the optical cables inserted therein, so that the optical cables are fixed to the outer shell 11.
[0026] In some embodiments, the junction box body 10 includes a connection bracket 14. The connection bracket 14 is disposed within the receiving cavity 110 and connected to the base 112. The fiber optic splice tray 12 is fixed to the connection bracket 14.
[0027] In some embodiments, the outer casing 11 is made of stainless steel, which gives the outer casing 11 high strength and good corrosion resistance.
[0028] Please see Figure 1 and Figure 2 The camera module 22 is located within the receiving cavity 110. The camera module 22 includes a camera. The camera module 22 is used to capture images of the fiber optic splice tray 12 and send the captured video to the main control module 21. The main control module 21 analyzes the received video and determines whether the fiber optic splice tray 12 has malfunctioned. A malfunction of the fiber optic splice tray 12 may include a breakage at the splice point between the spliced optical cables. The main control module 21 may be an MCU (Microcontroller Unit). When the main control module 21 determines that the fiber optic splice tray 12 has malfunctioned, it can send an alarm signal to the terminal device 210, thereby reminding maintenance personnel to handle the situation as soon as possible. Simultaneously, the main control module 21 can send the received video to the terminal device 210, facilitating timely understanding of the status of the fiber optic splice tray 12 by management and maintenance personnel. This application places the camera module 22 within the outer shell 11 of the junction box body 10. By capturing images of the fiber optic splice tray 12 with the camera module 22, the malfunction risk of the fiber optic splice tray 12 can be accurately identified, reducing the risk of misjudgment caused by external factors such as environmental interference.
[0029] In some embodiments, terminal device 210 includes at least one of an operation center master station or a mobile terminal. The operation center master station can be used to control the entire power communication system 200. The mobile terminal can include at least one of a smartphone or a tablet computer.
[0030] Please see Figure 2 The fiber optic junction box 100 includes a storage module 30. The storage module 30 is electrically connected to the camera module 22 to transmit the video captured by the camera module 22 to the storage module 30 for storage. The storage module 30 can be an SD card.
[0031] Please see Figure 2 The fiber optic splice box 100 includes a tilt sensor 23. The tilt sensor 23 is located on the splice box body 10 and electrically connected to the main control module 21. The splice box body 10 can be installed on a high-voltage tower, and may tilt due to strong winds. The tilt sensor 23 detects the tilt angle of the splice box body 10 and sends the detection data to the main control module 21. The main control module 21 analyzes the received detection data and determines whether the tilt angle exceeds a predetermined value. When the tilt angle received by the main control module 21 exceeds the predetermined value, the main control module 21 can send an alarm signal to the terminal device 210. By setting the tilt sensor 23, the tilt angle of the splice box body 10 can be directly detected, accurately identifying the risk of loosening or displacement of the splice box body 10, and reducing the risk of misjudgment caused by external factors such as environmental interference.
[0032] In some embodiments, the tilt sensor 23 is disposed within the receiving cavity 110. In another embodiment, the tilt sensor 23 is integrated into the main control module 21.
[0033] Please refer to the following: Figure 2 The optical cable junction box 100 includes a temperature sensor 24, which is located inside the housing cavity 110 and electrically connected to the main control module 21. The temperature sensor 24 detects the temperature inside the housing cavity 110 and sends the detection data to the main control module 21. The main control module 21 analyzes the received detection data and determines whether the temperature inside the housing cavity 110 exceeds a predetermined value. When the temperature received by the main control module 21 exceeds the predetermined value, the main control module 21 can send an alarm signal to the terminal device 210. By placing the temperature sensor 24 inside the housing cavity 110, the temperature inside the housing cavity 110 can be directly detected, accurately identifying the risk of sealing failure or icing and moisture absorption of the outer casing 11, and reducing the risk of misjudgment caused by external factors such as environmental interference. In some embodiments, the temperature sensor 24 can be integrated into the main control module 21.
[0034] Please refer to the following: Figure 2The optical cable junction box 100 includes a humidity sensor 25, which is located inside the housing cavity 110 and electrically connected to the main control module 21. The humidity sensor 25 detects the humidity inside the housing cavity 110 and sends the detection data to the main control module 21. The main control module 21 analyzes the received detection data and determines whether the humidity inside the housing cavity 110 exceeds a predetermined value. When the humidity received by the main control module 21 exceeds the predetermined value, the main control module 21 can send an alarm signal to the terminal device 210. By placing the humidity sensor 25 inside the housing cavity 110, the humidity inside the housing cavity 110 can be directly detected, accurately identifying the risk of sealing failure or icing and moisture absorption in the outer casing 11, and reducing the risk of misjudgment caused by external factors such as environmental interference.
[0035] Please see Figure 2 The optical cable junction box 100 includes a positioning module 26, which is electrically connected to the main control module 21.

[0036] In some implementations, the positioning module 26 includes a GPS unit or a BeiDou unit to obtain the geographic latitude and longitude information of the optical cable junction box 100.

The communication module 27 is communicatively connected to the terminal device 210. The main control module 21 can transmit signals to the terminal device 210 through the communication module 27.
[0038] In some implementations, the communication module 27 is a wireless communication module, which can be implemented based on satellite communication, 5G communication, or WiFi communication. Setting the communication module 27 as a wireless communication module eliminates the need for a communication optical fiber as a sensing medium, thus reducing costs.
[0039] Please see Figure 2 The optical cable junction box 100 includes a power module 29, which is electrically connected to the main control module 21. The power module 29 supplies power to the various components of the optical cable junction box 100. The power module 29 includes a power source 291 and a battery 292. The power source 291 is electrically connected to the battery 292 and is used to charge the battery 292. In some embodiments, the power source 291 includes at least one of a solar panel or a wind turbine. The battery 292 is electrically connected to the main control module 21.

[0040] Please see Figure 2The power module 29 includes a charging management module 293. The charging management module 293 includes a charging management chip. The charging management module 293 is electrically connected to the power supply 291 and the battery 292, and is used to control the charging of the battery 292. In some embodiments, the charging management module 293 is integrated into the main control module 21.
[0041] In some implementations, the power supply 291 is electrically connected to the main control module 21, and the power supply 291 can directly power the various components. In this case, when the power supply 291 is not working, the battery 292 powers the various components.
[0042] Please see Figure 1 and Figure 2 The power communication system 200 includes an optical cable splice box 100, a terminal device 210, and multiple optical cables (not shown). The multiple optical cables pass through the optical cable holes of the splice box body 10 and are fused to the optical fiber fusion splice tray 12. The main control module 21 communicates with the terminal device 210 via a communication module 27. A camera module 22 can capture video of the optical fiber fusion splice tray 12 in real time and transmit it to the main control module 21. A tilt sensor 23 can detect the tilt angle of the splice box body 10 in real time and transmit it to the main control module 21. A temperature sensor 24 and a humidity sensor 25 can detect the temperature and humidity inside the receiving cavity 110 of the splice box body 10 in real time. When the main control module 21 determines that the optical fiber fusion splice tray 12 has malfunctioned based on the received video, or when the tilt angle, temperature, or humidity received by the main control module 21 exceeds a predetermined value, the main control module 21 sends an alarm signal to the terminal device 210 via the communication module 27. By placing the camera module 22, tilt sensor 23, temperature sensor 24, and humidity sensor 25 on the junction box body 10, the state of the junction box body 10 can be directly and accurately detected, reducing the risk of misjudgment caused by external factors such as environmental interference.
