Description
Technical Field
The invention relates to the technical field of gateways, in particular to an optical network and wireless network converged communication gateway and a using method thereof.
Background
Optical fiber communication is a communication method that uses light waves as carrier waves and optical fibers as transmission media to transmit information from one place to another. The optical fiber communication mode is far superior to the cable and microwave communication modes in the following aspects: wide transmission frequency band, high anti-interference performance and reduced signal attenuation.
The power optical cable is mainly used as a conducting wire, and an optical fiber propagation medium is compounded in the power optical cable so as to be convenient for signal transmission. Currently, the power optical cable is classified into four types of an all-dielectric self-supporting optical cable (ADSS optical cable), an optical fiber composite overhead ground wire (OPGW optical cable), an optical phase conductor (OPPC optical cable), and an optical fiber composite low-voltage cable (OPLC optical cable).
Although the effect of optical fiber transmission signals is superior to that of cables and wireless communication, the optical fiber transmission signals are limited by optical fiber manufacturing materials, the requirement on optical fiber layout conditions is high, and a front-end network is not easy to construct. A fusion concept of wireless communication and optical fiber communication in a power system is introduced in technical research on application of fusion communication technology in power line monitoring (author: liu yi shuo) published in 2019, 5.6.s.a master thesis, in which an optical network and wireless network fusion communication gateway is arranged at an OPGW junction box, and a wireless signal sent by a wireless sensor is received by the fusion communication gateway, converted into an optical communication signal, and then transmitted to a target position by an optical fiber in an OPGW optical cable. However, this document does not deal with how to mix signals related to wireless signals without affecting the optical fiber signals in the OPGW optical cable.
