Description
Technical Field
The invention relates to the technical field of electronic communication, in particular to a photoelectric adapter and a power distribution system.
Background
At present, in building information communication, intellectualization and Internet of things engineering construction, an infrastructure of broadband transmission generally introduces a single 1-core/2-core optical cable transmission line into a certain user terminal for signal transmission, and a working power supply of terminal equipment is obtained nearby from a 220V alternating current power supply socket arranged in a building. In order to solve the problem that a plurality of terminal devices are difficult to get electricity, manufacturers in the wiring industry release a photoelectric hybrid cable, optical fibers and electric wires are combined into one hybrid cable, point-to-point application is achieved, an optical fiber transmission line and a power supply are provided for the terminal devices, and only a single signal and a single power supply line are provided. The two application types can occupy a large amount of limited pipe slot resources in the original building, and particularly for the reconstruction engineering of the existing building information communication facilities, the types of laid cables are increased, so that the investment and construction cost of engineering equipment are increased, and the energy consumption is increased.
At present, most of existing information facility ports of buildings are electrical ports, and with the development of an IP network and the requirements of terminal equipment on information bandwidth, transmission distance and information security, technical requirements for optical fiber transmission are provided. Because the information communication terminal equipment in the building has high density and the setting position is difficult to determine, an alternating current power socket arranged in the civil engineering electrical design of the building cannot meet the requirements of various high-density information facilities on power supplies, and the electronic circuit of the information communication terminal equipment actually uses a low-voltage direct current power supply, and when the power socket (which is a single-phase 220V alternating current power supply) provided by the electrical design of the building is used, power supply voltage stabilizing equipment is required to be added for power supply conversion, so that the energy consumption of the power supply is increased. The existence of the problems influences the environment beauty of the whole building, influences the safety of transmission routes, cannot ensure the nearby power supply problem of terminal equipment, and is not beneficial to the realization of the energy-saving target of green buildings advocated by the state.
Currently, the long-distance applications of hybrid optical/electrical cables, which are introduced by companies such as Huantian corporation and Conpu in the United states, are mainly "point-to-point" power supply for remote communication equipment and Power over Ethernet (PoE) equipment. The existing photoelectric hybrid cable has a single application scene, can only be applied to a certain information system, only solves the problems of information transmission (using a 2-core optical cable) and power supply (using a pair of electric wires) supply of single-point terminal equipment, and does not have the functions of photoelectric conversion and monitoring management. And only support hybrid optical and electrical cable applications consisting of optical fibers and electrical wires.
The existing application of adopting a photoelectric hybrid cable to provide a signal transmission line and a 220V alternating current power supply or a 48V power supply for remote terminal equipment is mainly point-to-point connection.

The other application scenario is used for a macro base station of mobile communication, the problem that signals of an outdoor unit of a base station antenna are led into mobile communication equipment of a machine room is solved mainly by adopting optical fibers, and the outdoor unit is powered by a wire. The above applications have the following disadvantages:
1. optical fibers and wires have limited applications and poor versatility.
2. Each photoelectric hybrid cable only serves a remote terminal device, so that the cables in the building are numerous and need to occupy more pipe and groove resources.
3. In the photoelectric hybrid cable, the transmission distance of optical fibers can reach more than 10 kilometers, the power supply distance of electric wires under a 48V power supply is reduced by about 10V due to line attenuation when the electric wires are connected into terminal equipment, the transmission distance can only reach 100-200 m, and the transmission distance between the electric wires and the terminal equipment is not matched.
4. If when setting up a great amount to the terminal equipment in an area, because of each mixed cable of photoelectricity needs a direct current supply circuit, then the block terminal equipment of the electrical installation large capacity of building, reduced power supply circuit's utilization ratio, increased distribution equipment's investment, and the building is difficult to solve the installation place scheduling problem of equipment, makes like this and uses the scene to have the limitation.
5. The functions of voltage division, power monitoring, optical/electrical signal conversion and the like of a power supply are not considered in the application of the existing photoelectric hybrid cable, one optical fiber route supports one terminal device, the resource utilization rate is low, and the system operation management is not facilitated.
6. The structure of the photoelectric hybrid cable enables the diameter of the cable to reach 12mm, the cost is increased, the utilization rate of the pipe groove is reduced, and the construction difficulty is increased.

The photoelectric adapter of the embodiment and various types of photoelectric hybrid cables form a photoelectric transmission power supply system, and an overall solution for application is provided for terminal equipment of various information communication and intelligent systems.
Further, according to an embodiment of the present invention, as shown in fig. 1, the optoelectronic adapter further includes a gateway module, which is electrically connected to the wiring module and the signal transmission module, and supports the signal transmission module to communicate with an external related terminal device through a reserved port of the wiring module according to actual user requirements.
According to the above embodiment of the present invention, the modules are all arranged in the box body as shown in fig. 1, and the box body can reserve a function expansion space for standby according to actual requirements.
Further, according to an embodiment of the present invention, the distribution module is a hybrid fiber and cable distribution module, which is composed of a fiber coupler, a coaxial cable socket, an RJ45 socket, a wire connection terminal and a power output terminal, and mainly completes input and output of various cables, and reserves ports required for service development and backup.
In the present embodiment, the optical fiber coupler employs an LC duplex connector and a coupler having a compact configuration. The transmission index of the connection meets the standard requirement, and the insertion loss is not more than 0.3 dB. When the 6-core and/or 12-core photoelectric hybrid cable passes through each intelligent photoelectric hybrid adapter, the lower 2-core optical fiber (which is a single-mode optical fiber) is connected to transmit signals.
The coaxial cable adopts a coaxial cable connector with 1 inlet (power supply and signal) and 2 outlets (wherein, the 1 outlet is a power supply and signal port, and the 1 outlet is a radio frequency, video, control and monitoring mixed signal + power supply output), and can be connected with SYV-75-3, SYV-75-5 and SYV-75-7 coaxial cables.

The reserved port supports the signal input of the external terminal equipment to the gateway module.
Further, in the present embodiment, the smart photoelectric adapter supports at most 6 optical paths for transmission of optical signals. However, if the terminal device is an electrical port, the optical signal needs to be converted into an electrical signal by the single-channel optical/electrical conversion device to access the electrical port of the terminal device, the optical/electrical conversion module meets the requirement that the transmission wavelength of the single-mode optical cable is 1310-1625 nm, and the optical fiber is connected with the port of the single core and/or the dual core. In this way, the terminal device which can retain the original electrical interface can be used continuously.
Further, in this embodiment, a power supply loop (48V) of the dc distribution equipment installed in the building supplies power to a plurality of (considering 1 to 6) intelligent photoelectric adapters through the coaxial cable (or wire) of the photoelectric hybrid cable, but the voltage loss after passing through a power supply distance of nearly 100 to 500m due to the coaxial cable or wire (1.5/2.5 square millimeter) makes the voltage lower than the working requirement of the equipment when reaching the installation position of the intelligent photoelectric adapter.

(1) and outputting a single 48V rated working voltage to support the power supply of the terminal equipment.
(2) According to the requirement of the working voltage of the terminal equipment, the voltage conversion and the voltage stabilization of the direct current are completed, and not less than 4 paths of 5-12V (adjustable) voltage are output, namely, the voltage is divided.

The module can divide the signal terminal of coaxial cable '1 in 2 out' into 4 branch channels (radio frequency, video, control and monitoring) and 1 power channel.
Further, in this embodiment, the dc power information monitoring and sensing communication module is intercommunicated with the functional modules, and monitors the input/output voltage, the operating current, the open circuit, the short circuit, and other conditions of the intelligent photoelectric adapter through the voltage/current sensor, and timely alarms when the power supply of the device is abnormal in the cycle time. A wire or wireless communication card is arranged in the module, monitoring signals can be sent to the APP platform or the related service management system through a communication network in time, monitoring information is analyzed in time, and line or equipment faults are processed.
Furthermore, as described above, in the present embodiment, the space reserved in the box body may house 4 gateway modules of the path. And supporting the signal transmission module to be communicated with external related terminal equipment through a reserved port of the wiring module according to the actual user requirement. The box body is made of PVG materials, the protection level of not lower than IP20 is achieved, and the color of the panel can be selected according to the needs of users.
According to the photoelectric adapter of the above embodiment of the present invention, actually, an important matter for the country to advocate new infrastructure is the construction of information infrastructure. From the angle, the invention aims to solve the problem that a large number of information facilities in buildings and building groups can ensure the supply of a safe power supply while the requirement of long-distance information transmission is met. When power is supplied to the power loads which are dispersedly installed at different positions and are unequal, the power supply can generate loss due to the internal resistance of the electric wire, and the reliable supply distance of the power supply cannot be ensured. The power supply part in the photoelectric adapter can use nominal direct current voltage, can still keep a constant working voltage under the requirements of different types of terminal equipment on power supply distance, power supply voltage and current, and can monitor the power supply quality of the power supply in real time.
