Description

Technical Field

[0001] This utility model relates to the field of signal transmission technology, and more specifically, to a real-time signal transmission device. Background Technology

[0002] In the fields of fiber optic communication and real-time signal transmission, signal transmission devices are key components connecting fiber optic cables to terminal equipment, and are widely used in industrial control, security monitoring, data centers, and the Internet of Things (IoT). Traditional fiber optic splitters or signal transmission devices typically employ a fixed-size, enclosed housing structure, with pre-designed cable channels or clips used to store the fiber optic cables. However, this fixed design has many limitations in practical applications, especially when dealing with fiber optic cables of varying lengths. It often cannot flexibly adjust the internal space, leading to excessive cable bending or difficulty in complete cable storage, thus affecting signal transmission quality.

[0003] Most signal transmission devices on the market currently use a one-piece housing with non-adjustable internal space. Therefore, when installing long fiber optic cables, operators usually need to forcibly coil the excess cable within a limited space. This may result in an excessively small bending radius of the cable, increasing optical signal loss and even causing physical damage to the cable sheath. In addition, the cover structure of traditional devices often uses bolt fixing, requiring the installation and removal of multiple screws each time it is opened or closed, which is cumbersome and not conducive to quick maintenance or adjustment of cable layout. Utility Model Content

[0004] 1. Technical problems to be solved

[0005] To address the problems existing in the prior art, the purpose of this utility model is to provide a real-time signal transmission device. In this solution, the inner cavity of the outer shell and the inner shell together form a space that can accommodate optical fiber cables. Moreover, the inner shell can be adjusted within the inner cavity of the outer shell, so that the user can change the size of the space jointly formed by the outer shell and the inner cavity according to the length of the optical fiber cable. This design can effectively improve the device's ability to accommodate optical fiber cables when the cable is long, and reduce the overall size of the device when the cable is short, making it easier to store and install, improving installation efficiency, and enhancing the practicality and convenience of the device.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Example:

[0033] Please see Figure 1-2 A real-time signal transmission device includes a housing 1, an inner housing 2, and a signal transmission component. The upper ends of both the housing 1 and the inner housing 2 are open. Both ends of the inner wall of the housing 1 are provided with sliding grooves 4. Both ends of the inner housing 2 are fixedly connected with sliders 5 that match the sliding grooves 4. Multiple signal transmission interfaces 3 are installed on the end of the inner housing 2 away from the housing 1. Both ends of the housing 1 are provided with first threaded holes 8. Limiting screws 7 are internally threaded into the first threaded holes 8. Both ends of the inner housing 2 are provided with multiple limiting holes 6 arranged at equal intervals. The limiting screws 7 match the limiting holes 6 and pass through the limiting holes 6.

[0034] In the installation of fiber optic cables inside a splitter, multiple fiber optic cables need to be coiled up inside the splitter. This serves two purposes: firstly, to organize the cables, and secondly, to ensure the cables are in good condition and avoid excessive bending. However, when the cable length is long, the number of coils increases, and the limited space inside the splitter may not be able to accommodate all the cables. In this solution, the user connects the fiber optic cable to the signal transmission interface 3 for splitting, and places the fiber optic cable inside the cavities of the outer shell 1 and the inner shell 2. The inner shell 2 can slide within the groove 4 on the inner wall of the outer shell 1 using a slider 5, thereby changing the size of the space formed by the cavities of the outer shell 1 and the inner shell 2. By threading the limiting screw 7 to the first threaded hole 8 and passing through the limiting hole 6, the inner shell 2 can be fixed in the current position during adjustment. With this setting, when the fiber optic cable is long and difficult to store, the inner shell 2 can be pulled to the outside of the outer shell 1 to increase the combined space of the inner cavity of the outer shell 1 and the inner shell 2. This increases the range of cable coiling in the inner cavity of the outer shell 1 and the inner shell 2, thereby reducing the number of cable coiling turns and allowing the device to accommodate more cables. Similarly, when the cable is short and does not require much storage space, the user can also push the inner shell 2 to the inside of the outer shell 1 to reduce the overall size of the device, thus facilitating storage and installation.

[0035] A pair of symmetrical first baffles 9 are fixedly connected to the bottom of the inner wall of the inner shell 2. The pair of first baffles 9 are close to the inner walls on both sides of the inner shell 2. A second baffle 15 is fixedly connected to the bottom of the inner wall of the outer shell 1. The second baffle 15 is close to the inner wall of the inner shell 2 on the side away from the outer shell 1.

[0036] When the user coils the fiber optic cable, the cable can be clamped between the first baffle 9 and the inner wall of the inner shell 2, and between the second baffle 15 and the inner wall of the second threaded hole 14, to ensure that the cable abuts against the inner walls of the outer shell 1 and the inner shell 2, thereby maximizing the coiling range of the cable. This setting not only improves the storage capacity of the device, but also reduces the bending degree of the cable, ensuring the effective transmission of the cable.

[0037] Please see Figure 1-3 The inner wall of the inner shell 2 is rotatably connected to an inner cover plate 10 that matches the inner cavity. An opening hole 11 is provided on the inner cover plate 10. A positioning plate 12 is fixedly connected to the inner wall of the inner shell 2 on the side away from the rotating end of the inner cover plate 10. The upper end of the outer shell 1 is rotatably connected to a matching outer cover plate 13. The upper surface of the inner shell 2 and the upper surface of the outer shell 1 are at the same horizontal position. A pair of second threaded holes 14 are provided at one end of the outer shell 1. A through hole matching the second threaded holes 14 is provided at the end of the outer cover plate 13 away from its rotating end.

[0038] After the user completes the installation of the fiber optic cable, the inner cover plate 10 can be rotated to cover the upper side of the inner shell 2. The opening hole 11 makes it easy for the user to lift the inner cover plate 10. The positioning plate 12 can support the inner cover plate 10 after it is rotated down. Then the user rotates the outer cover plate 13 to cover the outer shell 1. Finally, the outer cover plate 13 can be fixed by screws through the through hole and connecting with the second threaded hole 14. Since the inner cover plate 10 is always located under the outer cover plate 13 and abuts against the outer cover plate 13, the inner cover plate 10 cannot be opened after the outer cover plate 13 is fixed. This completes the covering of the cable and can effectively protect the cable.

[0039] Please see Figure 4 The signal transmission components include:

[0040] The signal acquisition module is used to receive signals input from signal transmission interface 3;

[0041] The signal conversion module, electrically connected to the signal acquisition module, is used to convert analog signals into digital signals;

[0042] The data processing module is connected to the signal conversion module via a data bus;

[0043] The wireless transmission module is connected to the data processing module via an SPI interface;

[0044] The power management module provides operating voltage to each module.

[0045] It should be noted that in this embodiment, the specific implementation is as follows:

[0046] The signal acquisition module includes a programmable gain amplifier and an anti-aliasing filter, with the output of the programmable gain amplifier connected to the input of the anti-aliasing filter.

[0047] The signal conversion module uses a Σ-Δ ADC chip with a sampling accuracy of no less than 16 bits and a sampling rate of no less than 100 ksps.

[0048] The data processing module includes an STM32 series microcontroller with built-in FIR digital filters and signal compression units.

[0049] The wireless transmission module adopts a dual-mode communication architecture, including:

[0050] BLE 5.0 unit, used for short-range, low-power transmission;

[0051] LoRa units are used for long-distance transmission.

[0052] The BLE 5.0 unit and the LoRa unit switch their communication modes via an analog switch, which is controlled by the GPIO port of the data processing module.

[0053] The power management module includes:

[0054] Lithium battery power supply unit;

[0055] The voltage conversion unit provides both 3.3V and 5V outputs.

[0056] Working principle:

[0057] In use, the user connects the optical fiber to the signal transmission interface 3 for branching, and places the optical fiber cable inside the cavities of the outer shell 1 and inner shell 2. The inner shell 2 can slide within the groove 4 on the inner wall of the outer shell 1 via the slider 5, thereby changing the size of the space formed by the cavities of the outer shell 1 and inner shell 2. By threading the limiting screw 7 into the first threaded hole 8 and passing through the limiting hole 6, the inner shell 2 can be fixed in its current position during adjustment. When the optical fiber cable is long and difficult to store, the inner shell 2 can be pulled outward from the outer shell 1 to increase the combined space of the cavities of the outer shell 1 and inner shell 2. When the cable is short, no excessive storage space is required. Alternatively, the inner shell 2 can be pushed inwards to reduce the overall size of the device, making it easier to store and install. Then, when the user coils the fiber optic cable, the cable can be clamped between the first baffle 9 and the inner wall of the inner shell 2, and between the second baffle 15 and the inner wall of the second threaded hole 14. After the fiber optic cable is installed, the user can rotate the inner cover 10 to cover the upper side of the inner shell 2. Then, the user can rotate the outer cover 13 to cover the outer shell 1. Finally, the screw can be inserted through the through hole and connected to the second threaded hole 14 to fix the outer cover 13 and the inner cover 10.

[0058] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
