Description

Technical Field

[0001] The invention relates to university network construction, in particular to a university dormitory communication access system based on Ethernet all-optical network. Background Art

[0002] Currently, the products available on the market only support optical demodulation under Ethernet optical networks to wireless WiFi7 access points and electrical network access points (including WiFi6 mode and Gigabit (100M) network electrical port access). In the national design specifications, dormitories and hotels should also design cable TV and telephone systems. In view of this background, in the design of weak current information systems for university dormitory projects, two systems need to be added in addition to the network system, one for the cable TV system and one for the telephone system. This results in cumbersome design work, complex construction, increased construction costs, and is not conducive to later operation and maintenance management and troubleshooting, making it difficult to achieve the "one network" strategy for universities.

[0003] Among the existing product suppliers, only residential optical demodulation equipment (entry optical modems) has television, telephone, wireless, and network electrical port access functions, but its performance as a home device is limited, and it only has 1-3 electrical ports. It is not suitable for multi-person dormitory applications in colleges and universities, and does not meet the network performance requirements of modern college dormitories. The all-optical WiFi access points of industrial enterprises have big data exchange performance, WiFi functions, and electrical port access functions, but no voice functions or cable TV functions. It is necessary to design voice networks and TV networks in addition to network design, resulting in overlapping equipment and line design and construction, which increases construction costs.

[0004] The existing network design and application of college student dormitories has not yet realized full-optical network access to households. It is only full-optical to the floors. Access switches are laid out on the floors. The switches have 2.5G or 10G, 100G optical port access (SFP) for upstream and 24 or 48 Gigabit electrical port access for downstream. The network cables are connected to the dormitory information panel. This solution requires laying a large number of network cables horizontally on the floors, which has high construction costs, limited network speed, and is not conducive to the subsequent network system upgrade. In addition, voice network switches need to be laid out on the floors and connected to each dormitory room through telephone lines. Based on the requirements of the specification, wired network signals should also be designed to be connected to each dormitory room through coaxial cables on the floors. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the above-mentioned background technology and provide a university dormitory communication access system based on Ethernet all-optical network, so that it can achieve zero use of horizontal network cables on the floors, thereby reducing the cost. There is no need to redesign the cable TV network and voice telephone network for indoor terminal equipment, and there is no need to purchase WiFi equipment separately. The overall cost of weak electricity is reduced, which not only realizes the design of a network for colleges and universities, but also makes subsequent maintenance and management more convenient.

[0006] The present invention provides a university dormitory communication access system based on Ethernet all-optical network, including core layer equipment, transmission layer access equipment and terminal equipment, wherein the core layer equipment, transmission layer access equipment and terminal equipment are all connected via optical fiber or optoelectronic hybrid cable, and the terminal equipment is an Ethernet all-optical network access point WiFi7 all-in-one machine equipped in each dormitory.

[0008] In the above technical solution, the Ethernet all-optical network access point WiFi7 integrated machine is also provided with a routing module connected to the data information processing module, and the routing module is provided with a built-in WiFi antenna connected thereto.

[0009] In the above technical solution, the routing module has built-in IPv4 working unit and IPv6 working unit.

[0010] In the above technical solution, the Ethernet all-optical network access point WiFi7 all-in-one machine is provided with a 2.5G SFP interface and a dedicated interface for optical-electrical hybrid cable on the uplink, and a 10 / 100 / 1000BASE-T adaptive Ethernet interface on the downlink, and the built-in WiFi antenna is provided with a backward compatible wireless data working unit.

[0011] In the above technical solution, the Ethernet all-optical network access point WiFi7 integrated machine is provided with a POE protocol power supply interface and a low-voltage power supply interface on the uplink.

[0012] In the above technical solution, the Ethernet all-optical network access point WiFi7 all-in-one has a square shell, the top of the square shell is connected to the uplink 2.5G SFP interface and the dedicated interface for the optoelectronic hybrid cable, the bottom of the square shell is connected to the network TV signal interface and the voice telephone interface, one side of the square shell is connected to multiple downlink electrical ports, and the other side of the square shell is a side panel reserved for the expansion of the downlink electrical ports.

[0013] In the above technical solution, the core layer equipment is a campus network and an optical core switch group connected by optical fiber or optoelectronic hybrid cable.

[0014] In the above technical solution, the transmission layer access equipment includes an optical convergence switch and an optical access switch connected by optical fiber or optoelectronic hybrid cable. Each dormitory building is equipped with an optical convergence switch, each optical convergence switch is connected to multiple optical access switches, and each optical access switch is connected to the Ethernet all-optical network access point WiFi7 all-in-one equipped in the corresponding dormitory.

[0015] In the above technical solution, the optical core switch group is connected to the video and voice controller and the wireless controller respectively; the optical core switch group is connected to the aggregation switch in the teaching and office area through optical fiber or optoelectronic hybrid cable.

[0016] The college dormitory communication access system based on Ethernet all-optical network of the present invention has the following beneficial effects: The present invention is a set of all-optical network solutions and a dedicated optical demodulation TV telephone wireless access point WiFi7 all-in-one machine based on Ethernet all-optical network developed and designed for densely populated living environments such as university dormitories (apartments), large factory dormitories, and public rental housing. This technical solution will greatly reduce the amount of dormitory network cable laying, because the use of optical fiber instead reduces the use of non-ferrous metals, saves construction costs, and increases transmission speed, which is convenient for centralized management and creates a business card for the university network.

[0017] Each dormitory is equipped with 4 network information points, 1 WiFi signal, 1 TV signal and 1 telephone signal. The traditional laying scheme is to lay network cables from the weak current well to each information point. Each dormitory requires 5 network cables (including WiFi), 1 cable TV signal line and 1 telephone line. After adopting this technical scheme, each dormitory only needs to lay one optical fiber from the weak current well to the dormitory to replace all existing lines. With the existing engineering cost as a reference, the comprehensive unit price of one meter of network cable is 7.3 yuan, and the comprehensive unit price of one meter of optical fiber is 3.5 yuan. The cost of laying the line is only one-tenth of the traditional scheme. At the same time, the access switches in the weak current well and the weak current room are also synchronously optimized to optical port switches, which is one-fifth of the traditional network port switches. Only one integrated machine needs to be installed and laid indoors to realize 4-port synchronous communication and WiFi wireless coverage, TV signal, and telephone signal functions, and the network speed is also increased from the traditional 100M to the 1000M designed by the present invention. It greatly reduces the cost of the weak current communication part of the collective dormitory, and at the same time improves the speed of network hardware configuration.

[0021] See also Figure 3The Ethernet all-optical network access point WiFi7 integrated machine is provided with an optical mediation module for receiving optical signals and a data information processing module for communicating with an upper switch in sequence. The data information processing module is provided with a data exchange module and a TV voice module in the downstream, respectively.

In one or more embodiments, the routing module has an IPv4 working unit and an IPv6 working unit built in. The routing module is provided with a built-in WiFi antenna connected thereto.

[0022] The Ethernet all-optical network access point WiFi7 all-in-one machine is provided with a 2.5G SFP interface and a dedicated interface for optical-electrical hybrid cable on the uplink, and a 10 / 100 / 1000BASE-T adaptive Ethernet interface on the downlink, and the built-in WiFi antenna is provided with a backward compatible wireless data working unit.

[0023] The Ethernet all-optical network access point WiFi7 integrated machine is provided with a POE protocol power supply interface and a low voltage (0-80V) power supply interface on the uplink.

[0024] Example 2 This embodiment is basically the same as Embodiment 1, except that: See also Figures 4 to 8 The Ethernet all-optical network access point WiFi7 all-in-one has a square shell, the top of the square shell is connected to the uplink 2.5G SFP interface and the dedicated interface for the optoelectronic hybrid cable, the bottom of the square shell is connected to the network TV signal interface and the voice telephone interface, one side of the square shell is provided with access to multiple downlink electrical ports, and the other side of the square shell is a side panel reserved for the expansion of the downlink electrical ports.

[0025] This solution is mainly designed and developed for university faculty and student apartments (dormitories), a dedicated optical demodulation TV telephone wireless access point WiFi7 all-in-one machine based on Ethernet all-optical network.

[0026] The present invention proposes an all-optical network solution for college student dormitories and a dedicated optical demodulation TV phone wireless access point WiFi7 all-in-one based on Ethernet all-optical network. The solution is to lay out optical convergence switches and optical access switches in the weak current room or floor of the building, and then connect to the dormitory access point equipment through optical fiber or optoelectronic hybrid cable, that is, a dedicated optical demodulation TV phone wireless access point WiFi7 all-in-one based on Ethernet all-optical network. The device has high-speed data demodulation and switching functions, one 2.5GSFP interface and an optoelectronic hybrid cable dedicated interface in the upstream, four or more 10 / 100 / 1000BASE-T adaptive Ethernet interfaces in the downstream, a built-in intelligent antenna supports WiFi7 and backward compatible wireless data functions, supports cable TV ITV data interface, supports voice telephone interface, supports switching routing functions, supports IPv4 services, and IPv6 services.

[0027] The application of this equipment will realize full fiber-to-the-home (FTTH) in the dormitory environment of colleges and universities. All wiring is fiber-optic, and the use of horizontal network cables on the floor is eliminated, thereby reducing the cost. In addition, the indoor terminal equipment has cable TV, voice, and WiFi functions, so there is no need to redesign the cable TV network and voice telephone network, nor to purchase WiFi equipment, which reduces the overall cost of weak current, and realizes the design of a single network for colleges and universities, making subsequent maintenance and management more convenient.

[0028] This solution is mainly divided into two parts, including the hardware of indoor optical terminal equipment in university dormitories and the design of all-optical network system. Based on the original enterprise WiFi terminal, this solution optimizes the cable TV signal and voice telephone signal, clarifies the system principle and various interface forms, so as to better apply it to the weak current network system of university dormitories. At the same time, a new all-optical dormitory network architecture is proposed to realize the design of a network for universities, which is convenient for saving construction costs, operation and maintenance management, and fault repair.

[0029] The appearance and interface of the WiFi7 all-in-one machine for optical demodulation TV telephone wireless access point in college dormitories Figures 4 to 8 As shown, the device adds a network cable TV interface and a voice telephone interface on the basis of a conventional WiFi access point. The optical signal enters the device's uplink access port through an optical fiber or a hybrid optical cable. The optical port or the optical-electrical fusion interface supports POE protocol power supply for the uplink, and also supports low-voltage power supply mode. Local power supply or unified power supply can be adopted. In the dual power supply mode, the POE power supply mode is preferred.

[0030] See also Figure 3After the signal enters the interior, it is first demodulated by the optical demodulation module. After the signal is demodulated, it communicates with the upper switch through the data information processing module, and then transmits the signal to the TV voice module, data exchange module and routing module respectively. After the TV voice module analyzes and resolves the signal, it outputs the signal to the network TV signal interface and voice telephone interface of the device; one signal transmits the network signal to the downlink network port (RJ45) through the data exchange module. The device can be customized to expand the number of network ports by 4-12 according to user needs, that is, to meet the needs of multiple users indoors; another signal is wirelessly covered by the routing module and the built-in omnidirectional WiFi antenna, so that users can access the Internet wirelessly via WiFi.

[0031] The application of this solution can also realize the unified management of TV signals, remotely control TV broadcast content at special times, realize remote learning, hold meetings remotely, and watch ordinary TV programs. It can also access campus promotion signals and play promotional videos in a unified manner.

[0032] After comparative studies, the only possible alternative to the present invention is to invest in multiple devices such as optical-electrical switches, WiFi routers, TV boxes, and telephone signals to achieve this function. However, the investment and installation of multiple devices will greatly increase the cost and will be unfavorable for management and troubleshooting, making it difficult to achieve "one network" coverage on campus.

[0033] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.

[0034] The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
