Network transmission equipment based on EOC (Ethernet over Coax)

Abstract

This invention provides a network transmission equipment based on EOC. The network transmission equipment comprises a front-end network equipment, an EOC equipment, an EOC node computer and a receiver; the network equipment is in a communication connection with the EOC equipment through a cable; the EOC equipment is in a communication connection with the EOC node computer through a coaxial cable; the EOC node computer is in a communication connection with the receiver through an optical port or an electric port; the EOC node computer or the EOC equipment can supply power to each other through the coaxial cable; signals on the coaxial cable are transmitted through a protection module, a filter isolation module, a signal amplifying module and a coding / decoding module in sequence; the filter isolation module is used for filtering interference; the signal amplifying module is used for transmitting the signals remotely; a data analog converter used for reciprocally converting analog signals and digital signals is arranged between the signal amplifying module and the coding / decoding module; and the coding / decoding module is used for coding / decoding the digital signals. The network transmission equipment can smoothly solve wiring and transmission problems, can supply power coaxially, and can improve the network transmission performance.

Description

technical field [0001] The invention relates to the technical field of network transmission, in particular to EOC-based network transmission equipment. Background technique [0002] Network transmission can effectively solve the problem of video bandwidth. At present, most of the high-definition surveillance equipment on the market is between network transmission. For some old monitoring equipment, analog bolt cameras and ball cameras are used in design and planning, and the transmission medium is coaxial cables. With the high-definition of video surveillance, it is necessary to transform ordinary surveillance equipment into high-definition network cameras, and this part of the line was originally transmitted by coaxial cables. Due to the internal pipes and complicated wiring, it is not conducive to line transformation. Therefore, when the front-end monitoring equipment is changed to a network high-definition camera and ball camera, there is an urgent need for a transmissio...
