Description

Technical Field

[0001] This utility model relates to the field of communication power supply technology, specifically to a power supply and communication system that supports wide-voltage DC input and optoelectronic composite cascading. Background Technology

[0002] Existing power supply and communication solutions for remote devices include AC power supply, PoE (Power over Ethernet), fiber optic communication, and Power over Fiber (POF). Traditional AC power supply or PoE suffers from short transmission distances (PoE typically <100 meters), high line loss, susceptibility to electromagnetic interference, and cumbersome cabling. While fiber optic communication can solve long-distance and interference issues, it requires separate power supplies for remote devices, resulting in high costs and complex deployment. Although POF technology enables simultaneous optical and electrical transmission, existing systems are mostly limited to point-to-point architectures, have poor scalability, struggle to build complex cascaded device networks, and lack intelligent wide-range adaptability to input voltage.

[0003] In summary, existing technologies lack a power supply and communication system that can simultaneously achieve wide-voltage, high-efficiency cascaded power transmission, flexible local power supply, and optical communication signal distribution and transparent transmission. Utility Model Content

[0004] To address the aforementioned problems in the prior art, this utility model provides a power supply and communication system that supports wide-voltage DC input and optoelectronic composite cascading, solving the problem that the prior art lacks a power supply and communication system that can simultaneously achieve wide-voltage high-efficiency cascaded power transmission, flexible local power supply, and optical communication signal distribution and transparent transmission.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A power supply and communication system supporting wide-voltage DC input and optoelectronic composite cascading is provided, including a PSE module. The input terminal of the PSE module is electrically connected to a power input interface and a cascading input terminal. Both the power input interface and the cascading input terminal are electrically connected to a boost module, and the boost module is electrically connected to a cascading output terminal. The output terminal of the PSE module is electrically connected to the interface of the local device. The cascading input terminal, the cascading output terminal, and the local device interface are all connected to an optical splitter via optoelectronic composite optical cables. The cascading input terminal is used to receive signals from the local device or the upstream device via the optoelectronic composite cable, and the cascading output terminal is used to output optoelectronic signals to the downstream device.

[0006] The working principle of this solution is as follows: The power supply and communication system includes host mode and extender mode. When the power supply and communication system is in host mode, the external power supply is input from the power input interface and split into two paths. One power supply is output from the cascade output terminal through a boost module, and the other power supply is sent to the interface of the local device through the PSE module. The cascade input terminal receives the optical signal from the local device. After being distributed by the optical splitter, part of the optical signal is used for the local device, and the other part of the optical signal is combined with the power supply output from the cascade output terminal and output to the next-level device.

[0007] When the power supply and communication system is in extender mode, the upstream device is connected to the cascade input of the local device via a composite optical-electrical cable. One electrical signal is sent to the boost module and output from the cascade output to continue providing wide-voltage power to downstream devices. The other electrical signal is sent to the local device interface via the PSE module to power the local load device. The optical signal enters the common terminal of the optical splitter, which distributes the optical signal according to a certain ratio. A portion of the optical signal is supplied to the local device, and the remaining optical signal is sent to the optical signal terminal of the cascade output. The cascade output output, through a composite optical and electrical signal cable, outputs the signal to the downstream device, achieving continuous expansion.

[0008] Thus, the power supply and communication system of this solution compactly integrates three major functions: wide voltage output, local equipment power supply, and optical communication signal distribution and transparent transmission. Moreover, the power supply and communication connection to the downstream equipment can be completed through a single optical fiber composite cable, which greatly simplifies the deployment complexity and cost of remote equipment.

[0009] Furthermore, the PSE module is electrically connected to the power input interface and cascade input terminals via a buck-boost module. The buck-boost module can maintain the electrical signals at a certain voltage at the power input interface and cascade input terminals, achieving a wide input range while stably outputting the voltage required by the PSE module.

[0010] Furthermore, the output voltage of the buck-boost module is 48~60V. The buck-boost module is designed to adapt to a wide input range of 48-60V and stably output the required voltage. The power path design is clear, with the boost and buck modules each performing their respective functions, ensuring stable and efficient power supply to this stage and downstream equipment, and high energy utilization.

[0011] Furthermore, the output voltage of the boost module is 5~100V. The boost module can use up to 100V for cascaded power transmission, which significantly reduces line transmission loss and supports long-distance, multi-device cascading expansion over hundreds of meters, far exceeding the distance limitations of traditional PoE.

[0012] Furthermore, the common terminal of the optical splitter is connected to the optical signal of the cascade input terminal, and the transparent branch of the optical splitter is connected to the optical signal of the cascade output terminal.

[0013] Furthermore, the optical splitter connects to the local device interface via a photoelectric converter. The photoelectric converter converts the optical signal distributed from the optical splitter into an electrical signal, enabling standard Ethernet devices (which only receive electrical signals) to seamlessly access the system.

[0014] Furthermore, the splitting ratio between the optical signal input to the local device interface and the optical signal input to the cascaded output is 1:9. Allocating 10% of the optical signal energy to the local level satisfies the basic bandwidth requirements for local device status monitoring or local communication, while simultaneously transmitting the vast majority of the energy to the next level. This maximizes the signal strength and stability of the cascaded communication backbone, achieving an optimal balance between cascading capability and local service capability.

[0016] The specific embodiments of this utility model are described below to enable those skilled in the art to understand this utility model. However, it should be understood that this utility model is not limited to the scope of the specific embodiments. For those skilled in the art, as long as various changes are within the spirit and scope of this utility model as defined and determined by the appended claims, these changes are obvious. All utility model creations utilizing the concept of this utility model are within the scope of protection.

[0017] refer to Figure 1 This embodiment provides a power supply and communication system that supports wide-voltage DC input and optoelectronic composite cascading. The purpose is to solve the problem that the existing technology lacks a power supply and communication system that can simultaneously realize wide-voltage high-efficiency cascaded power transmission, flexible local power supply, and optical communication signal distribution and transparent transmission. It includes a power input interface 1, a PSE module 2, a boost module 3, a boost-buck module 4, a cascade input terminal 5, a cascade output terminal 6, a local device interface 7, and an optical splitter 8.

[0018] The input terminal of PSE module 2 is electrically connected to power input interface 1 and cascade input terminal 5. The output terminal of PSE module 2 is electrically connected to the local device interface 7. Alternatively, PSE module 2 can be electrically connected to power input interface 1 and cascade input terminal 5 via buck-boost module 4. The output voltage of buck-boost module 4 is 48~60V, preferably 56V. The design of buck-boost module 4 allows it to adapt to a wide input range of 48-60V and stably output the required voltage. The power path design is clear, with the boost and buck modules each performing their respective functions, ensuring stable and efficient power supply to local and downstream devices, resulting in high energy utilization.

[0019] Both the power input interface 1 and the cascade input terminal 5 are electrically connected to the boost module 3, and the boost module 3 is electrically connected to the cascade output terminal 6. In this embodiment, the output voltage of the boost module 3 can be 5~100V, preferably 100V. Using 100V for cascaded power transmission significantly reduces line transmission loss and supports long-distance, multi-device cascaded expansion over hundreds of meters, far exceeding the distance limitations of traditional PoE.

[0020] Cascading input 5 is used to receive signals from the local or upstream device via a fiber optic composite cable, and cascading output 6 is used to output the fiber optic signal to the downstream device. Cascading input 5, cascading output 6, and the local device interface 7 are all connected to optical splitter 8 via fiber optic composite cables.

[0021] Specifically, the common terminal of optical splitter 8 is connected to the optical signal of cascade input terminal 5, and the transparent branch of optical splitter 8 is connected to the optical signal of cascade output terminal 6. Optical splitter 8 is connected to the local device interface 7 through an opto-converter. The opto-converter converts the optical signal distributed from optical splitter 8 into an electrical signal, thereby enabling standard Ethernet devices to seamlessly access the system.

[0022] In this embodiment, the splitting ratio between the optical signal input to the local device interface 7 and the optical signal input to the cascade output terminal 6 of the optical splitter 8 is 5%~30%:70%~95%. Preferably, in this embodiment, the splitting ratio of the optical splitter 8 is 10%:90%, allocating 10% of the optical signal energy to the local level. This satisfies the basic bandwidth requirements for local device status monitoring or local communication, while also transmitting the vast majority of the 90% energy to the next level. This maximizes the signal strength and stability of the cascaded communication backbone, achieving an optimal balance between cascading capability and local service capability.

[0023] Preferably, but not limited to, the boost module 3 is model YX21105, the boost-boost module 4 is model YX22105, the PSE module 2 and the optical splitter 8 are existing technologies, and their specific working principles and connection relationships will not be described in detail in this embodiment.

[0024] In summary, the working principle of this solution is as follows: The power supply and communication system includes a host mode and an expansion mode.

[0025] When the power supply and communication system is in host mode, an external 5V~100V voltage is input from the power input interface 1 and split into two paths. One power supply is boosted to 100V by the boost module 3 and output from the cascade output terminal 6. The other power supply is output at 56V through the buck-boost module 4 to the PSE module 2. The PSE module 2 then transmits the signal to the local device interface 7. The cascade input terminal 5 receives the optical signal from the local device. After being distributed by the optical splitter 8, 10% of the optical signal is used for the local device, and 90% of the optical signal is transmitted through and combined with the power output from the cascade output terminal 6 for output to the next-level device.

[0026] When the power supply and communication system is in extender mode, the upstream device is connected to the cascade input terminal 5 of the local device via a composite optical-electrical cable. One electrical signal is sent to the boost module 3 to be boosted to 100V and output from the cascade output terminal 6 to continue providing wide-voltage power to downstream devices. The other electrical signal is stabilized at 56V by the buck-boost module 4 and then enters the PSE module 2. The PSE module 2 sends the signal to the local device interface 7 to power the local load device. The optical signal enters the common terminal of the optical splitter 8, which distributes the optical signal at a 1:9 ratio: 10% of the optical power is supplied to the local device, and 90% of the optical power is sent to the optical signal terminal of the cascade output terminal 6. The cascade output terminal 6 outputs the composite 100V electrical signal and 90% of the optical power to the downstream device via a composite optical-electrical cable, achieving continuous expansion.

[0027] Although specific embodiments of the utility model have been described in detail with reference to the accompanying drawings, this should not be construed as limiting the scope of protection of this solution. Various modifications and variations that can be made by those skilled in the art without inventive effort within the scope described in the claims still fall within the scope of protection of this solution.
