Description

Technical Field

[0001] This utility model relates to the field of carrier communication technology, specifically to a pluggable repeater for low-voltage power line communication environments, and more particularly to a low-voltage carrier communication repeater that can connect to external devices via a slot-type interface and integrates power processing, signal acquisition, signal isolation and signal enhancement functions in a compact structure. Background Technology

[0002] Low-voltage carrier communication technology is a communication method that utilizes existing low-voltage power lines to transmit data signals. It offers advantages such as no need for additional wiring, low deployment costs, and wide coverage, and has been widely applied in fields such as smart lighting, smart metering, building automation, and power distribution monitoring. However, in practical applications, due to the inherent complexity of low-voltage power lines and their instability caused by load variations, carrier signals often experience attenuation, interference, and blockage during transmission, thus affecting communication reliability and coverage distance.

[0003] To improve the transmission quality of carrier signals in power line networks, repeater equipment is typically added at critical locations to amplify, isolate, and retransmit signals. However, existing repeater equipment generally suffers from the following problems: Fixed structure, inconvenient installation Most existing carrier communication relay equipment is an independent external structure, which requires additional wiring to connect to the system. It has limited installation space and is complicated to construct, making it unsuitable for deployment in compact equipment or modular systems.

[0004] Non-removable, making replacement and maintenance difficult. Traditional relay equipment is mostly fixed installation structure. If a fault occurs, the entire line needs to be disassembled or the equipment casing needs to be removed, which results in high maintenance costs and affects the continuous operation of the system.

[0005] Functional modules are scattered and the overall integration is low. Some repeaters distribute power processing, signal acquisition, isolation, and enhancement functions across different circuit boards or external devices, resulting in complex structures and large sizes, which are not conducive to use in devices with limited space.

[0006] Inconsistent interface formats hinder systematic management. The interface forms of relay devices vary in different application environments, and there is a lack of a unified modular plug-in method, which makes it impossible to achieve quick replacement and plug-and-play functionality.

[0007] Therefore, existing low-voltage carrier communication systems urgently need a small, compact, pluggable, easy-to-install, and easy-to-maintain relay device that can be integrated with equipment through a simple plug-in method and integrate various functional modules required for carrier relay internally, thereby improving the availability and operational reliability of low-voltage carrier communication systems. Summary of the Invention

[0008] The purpose of this invention is to overcome the problems of fixed installation methods, inconvenient replacement and maintenance, large structural size, and difficulty in integration with modular equipment in existing low-voltage carrier communication relay equipment. It provides a compact, pluggable low-voltage carrier communication relay device that can be easily connected to external device slots and complete carrier signal relay processing. This device integrates power processing, signal acquisition, signal isolation, and signal enhancement modules within its main body. Upon insertion into an external device slot, it acquires both power and carrier signals, processes the carrier signals, and outputs them, thus achieving plug-and-play communication relay functionality and improving the deployment convenience and maintenance efficiency of low-voltage carrier communication systems.

[0009] The technical solution of this utility model is as follows: a low-voltage carrier communication relay device, characterized in that it includes: — The relay module itself; — A module plug-in part located at one end of the relay module body is used to plug into the card slot interface of an external device; — A line connection part located at the other end of the relay module body is used to connect to an external power supply line or a carrier communication line; — A functional module group located inside the relay module body, the functional module group including a power processing module, a signal acquisition module, a signal isolation module and a signal enhancement output module arranged in sequence; When the relay module body is inserted into the slot of an external device, it obtains working power and carrier signal through the module plug-in part, and after being processed by the internal functional module group, the target communication signal is output by the line connection part.

[0010] Preferably, the module connector includes a gold finger connector, a metal contact group, a pin socket, or a snap-fit ​​connector.

[0011] Preferably, the line connection part is one of a socket port, a screw terminal block, a crimp terminal, or a conductive plug.

[0012] Preferably, the power processing module is used to perform voltage conversion and regulation on the power input through the module plug-in portion, so as to provide operating voltage for the signal acquisition module, signal isolation module and signal enhancement output module.

[0013] Preferably, the signal acquisition module is used to extract a carrier signal from the power line input from the module connector and to demodulate and shape the carrier signal.

[0014] Preferably, the signal isolation module includes an isolation chip or isolation circuit structure, which is used to structurally separate the reference grounds on the front and back sides of the isolation and avoid signal coupling.

[0015] Preferably, the signal enhancement output module includes an output driving circuit or a signal amplification unit for amplifying the isolated signal and outputting it to an external line.

[0016] Preferably, the functional modules are arranged on the same circuit board or on multiple circuit boards, and the multiple circuit boards are fixed in the relay module body in a stacked, side-by-side or layered structure.

[0017] Preferably, the power processing module, signal acquisition module, signal isolation module, and signal enhancement output module are arranged sequentially along the length of the relay module body.

[0018] Preferably, the relay module body is a replaceable structure, which can be plugged in and replaced when the external device is powered on or off.

[0019] This utility model has the following technical effects: Achieving stable relay transmission of carrier signals: By setting up a power processing module, a signal acquisition module, a signal isolation module, and a signal enhancement output module inside the relay module, the device can acquire, isolate, and amplify carrier signals from low-voltage power lines, thereby effectively improving the transmission distance and signal quality of carrier communication.

[0020] Compact structure and easy system integration: Each functional module is integrated into the relay module body, which significantly reduces the overall space occupied by the device. It is suitable for space-constrained terminal equipment, distributed access nodes and modular electronic devices, which helps to improve the overall integration of the system.

[0021] Plug and play, improving installation efficiency: The relay module can obtain working power and communication signals by directly inserting it into the slot of the external device through the module plug-in part, without the need for additional wiring or complicated installation process, which significantly reduces construction and layout costs.

[0022] Supports rapid replacement and maintenance, reducing system downtime: The relay module body has a pluggable structure, which can be quickly replaced whether the external equipment is powered on or off. When the module fails, there is no need to disassemble the equipment shell or damage the original wiring, thereby shortening maintenance time and improving system reliability.

[0023] An unexpected improvement in system compatibility is achieved through the combination of a "slot-type interface" and internally integrated functional modules. Traditional carrier repeaters need to be installed in parallel or series in the power line, while the repeater module of this invention uses a slot-type interface to simultaneously obtain power and carrier signals, enabling the module to be used in any device with the same slot interface, thus achieving universal deployment.

[0024] This feature not only simplifies wiring but also enables repeater modules to be "functionally pluggable," bringing unexpected compatibility and scalability to carrier communication systems.

[0025] The isolation module is located inside the module body, enabling the relay module to maintain stable operation in different power supply environments. The built-in signal isolation module can shield the main circuit of the device from interference, enabling the repeater module to operate stably under different power systems and grounding references, avoiding the ground interference coupling problem often found in traditional repeaters. This structure of "isolation and link enhancement completed within the card module" is rare in existing technology and belongs to a non-obvious combination.

[0026] It achieves "plug-in power supply + signal processing + line output" through a single module, possessing a higher level of functionality than traditional repeaters.

[0027] This invention achieves power supply, data acquisition, isolation, and amplification simultaneously within a very small module size. These multiple functions are realized in a single pluggable structure, making the module a “low-voltage carrier communication function plug-in”.

[0028] This structure brings a high degree of integration that is hard to achieve in traditional devices, making the whole system closer to an architecture with "pluggable expansion of communication capabilities", and the actual effect exceeds that of conventional repeater logic.

[0029] Supports rapid device-level upgrade capabilities Users can quickly upgrade communication coverage, signal strength, or protocol version by replacing repeater modules of different specifications without replacing the entire device.

[0030] Traditional repeaters do not have this "device-level module upgradeability" capability, so the maintainability and scalability brought by this utility model are unexpected improvements.

[0031] By adopting a pluggable modular structure and integrating a fully functional signal processing link within a compact module, this invention not only solves the problems of complex installation, difficult maintenance, and large size of existing low-voltage carrier communication repeaters, but also achieves unexpected technical effects such as system scalability, enhanced isolation stability, and rapid device-level upgrades, greatly improving the flexibility and reliability of low-voltage carrier communication systems.

[0038] The embodiments of this utility model will be further described below with reference to the accompanying drawings. Those skilled in the art should understand that the following embodiments are merely preferred embodiments of this utility model, and not limitations on the scope of protection of this utility model. Example

[0039] like Figures 1-5 As shown, a low-voltage carrier communication relay device includes a relay module body 1. One end of the relay module body 1 is provided with a module plug-in part 11 for plugging into a slot-type interface of an external device; the other end of the relay module body 1 is provided with a line connection part 12, which adopts a terminal block structure for reliable electrical connection with an external power line or carrier communication line.

[0040] like Figure 2 As shown, a functional module group is arranged inside the relay module body 1. This functional module group is arranged sequentially along the length of the module body, including a power processing module 2, a signal acquisition module 3, a signal isolation module 4, and a signal enhancement output module 5. The above modules can be integrated on the same circuit board, or they can be distributed on multiple circuit boards according to the spatial layout and fixed inside the relay module body by stacking, side by side, or layering.

[0041] In this embodiment, the module connector 11 can adopt a structure such as gold fingers, metal contact groups, or pin sockets, so that after the relay module body 1 is inserted into the external device slot, it can obtain the working power provided by the device and the input line carrying the carrier communication signal. The line connection part 12 adopts a two-hole terminal block structure, and the user can connect it to the external power line or carrier line by crimping or plugging to realize the output of the relay signal.

[0042] like Figure 3 As shown, in typical use, the relay module body 1 achieves mechanical and electrical connection with the external device via the module plug-in part 11 and the slot-type interface, and simultaneously connects to the external power line or carrier line via the line connection part 12, thereby constructing the input and output paths for carrier communication. Users only need to insert the relay module into the external device and connect the external line to complete the installation; no modifications to the internal structure of the external device are required.

[0043] like Figure 4 As shown, the signal processing path of this utility model is as follows: the power signal input from the module plug-in part 11 first enters the power processing module 2, and after voltage transformation and voltage regulation, it provides a stable operating voltage for the signal acquisition module 3, the signal isolation module 4, and the signal enhancement output module 5; the signal acquisition module 3 extracts and demodulates the carrier signal from the input power line; the signal isolation module 4 separates the reference grounds on both sides before and after isolation through an isolation chip or isolation circuit structure to reduce the influence of ground coupling on the communication signal; the signal enhancement output module 5 amplifies the isolated signal and outputs it from the line connection part 12 to the external communication line.

[0044] like Figure 5 As shown, for ease of understanding, this embodiment provides a simplified structural diagram of the main functional modules inside the relay module, illustrating the modular signal flow relationship from the input end to the output end.

[0045] In summary, in this embodiment, the coordinated action of the relay module body 1, the module plug-in part 11, the line connection part 12, and the functional module group enables the device to be quickly deployed in a carrier communication system in a pluggable manner, achieving carrier signal isolation, enhancement, and relay, thereby improving communication reliability and coverage. Simultaneously, the module can be quickly replaced under both powered and powered-off conditions, exhibiting good maintainability and compatibility.
