Overview of Traditional Industrial Digital Optical Network
The digital optical fiber network still has shortcomings: its terminal equipment is restricted, such as only a small number of sensors can be connected; it does not support or only supports a small number of wireless network equipment, and its mobility is limited; its network expansion is difficult, and it does not support the coexistence of multiple communication protocols. Terminal expansion is difficult, network upgrade and reconstruction are not easy, etc. Moreover, the signal coverage of the usual WiFi access point (AP) is: indoor, 50-100 meters; outdoor, 100-150 meters.
In order to achieve a larger range of WiFi signal distribution, we use the world’s leading optical fiber radio technology to transmit WiFi radio frequency signals through optical fibers, with a transmission distance of up to 5000 meters.
A new generation of industrial fiber optic radio technology
Optical fiber radio technology (radio-over-fiber communication) radio-over-fiber (ROF) technology is a newly developed wireless access technology that combines optical fiber communication and wireless communication in response to the needs of high-speed and large-capacity wireless communication. The optical remote radio system is a product driven by technology and cost, and is a manifestation of the initial combination of optical and wireless networks. It can greatly reduce the operator’s requirements for site resources, reduce investment, and effectively improve the coverage effect.
Compared with the conventional WiFi local area network, the Fei Ruiao WiFi fiber optic radio (optical wireless) signal distribution system has the following advantages:
(1) Realize low-cost, long-distance, and large-scale distribution of WiFi radio frequency signals.
(2) The WiFi optical fiber radio signal distribution system adopts the WiFi optical fiber radio center controller to centrally manage and control the WiFi local area network, which can greatly improve the reliability of the system, facilitate the management and maintenance of the network, and make the system network easy to upgrade.
(3) The remote node and radiating antenna of the WiFi optical fiber radio signal distribution system are simple in structure, which reduces the cost and complexity of the remote access point.
(4) The network protocol of the WiFi optical fiber radio signal distribution system adopts the standard TCP/IP network protocol, and the system is easy to expand.
(5) The WiFi optical fiber radio signal distribution system can realize remote control, management and data collection through WiFi local area network, which is especially suitable for wireless network signal distribution in large factories, docks, hospitals, smart buildings and other occasions.
(6) The WiFi fiber optic radio signal distribution system integrates fiber optic radio technology, WiFi wireless local area network, and can also be integrated into embedded Web device servers and RFID radio frequency identification technology. It realizes the integration of computer, communication and control, and is the realization of M2M. Networking) the best solution.
A new generation of industrial wireless network constructed by WiFi optical fiber radio signal distribution system:
The use of a new generation of industrial wireless communication network system can form a wireless M2M system, which integrates data collection, industrial control, remote monitoring and management, and serves as an ecosystem of computers, networks, equipment, sensors, humans, telecommunications, and information technology. Industrial control can automate business processes, integrate the real-time status of company information technology (IT) systems and non-IT equipment, and create value-added services. This platform can operate in environments such as safety monitoring, automatic meter reading, mechanical service and maintenance business, vending machines, public transportation systems, fleet management, industrial process automation, electric machinery, urban informatization and other environments and provide a wide range of applications and solutions plan.
About the core equipment of the system: optical carrier wireless switch
Optical wireless switch is a new generation of optical wireless network switch jointly developed by Guangzhou Fei Rui Ao Electronic Technology Co., Ltd. and Beijing University of Posts and Telecommunications.
The product concentrates the generation and processing of WiFi signals inside (the central computer room), realizes a large-scale (200 to 5000 meters) distribution with optical fibers, and completes signal coverage and two-way transmission through remote antennas. The product can mix and transmit WiFi and 2G3G4G and other wireless signals, which can save users a lot of investment in wireless network construction, avoid repeated construction, and greatly increase the speed of network construction.
Three main features of optical wireless switches:
1. Localization of wireless signal source: The wireless signal is generated by the optical carrier wireless switch, and after processing and conversion, it can be transmitted to the remote end of 200 meters to 5000 meters by the optical fiber. The advantages it brings are: 1. Centralized signal management. 2. Local equipment maintenance. 3. More secure and stable.
2. WIFI and 2G/3G signal mixed two-way transmission: 2G and 3G (and future 4G) signals are connected to the optical carrier wireless switch through the cable, and the WIFI signal is mixed and processed and converted into optical signals to be transmitted to the remote antenna to achieve mixing Two-way transmission of signals.
3. Realize the reconstruction of the wireless network: that is, when there is insufficient network bandwidth in a certain area due to too many users, communication is not smooth, and the network is blocked. The optical carrier wireless network system can be equipped with other idle WIFI signals to support this area and realize signal reconstruction.
