Detailed description of the invention
Below in conjunction with the accompanying drawings, embodiments of the invention are described in further detail.
As it is shown in figure 1, web-transporting device based on EOC, including the network equipment of front end, EOC equipment, EOC Node station
And receiver, the network equipment is communicated to connect by netting twine with EOC equipment, and EOC equipment and EOC Node station pass through coaxial cable communication
Connecting, EOC Node station is connected by light mouth or electricity port communications with receiver, and described EOC Node station can be EOC by coaxial cable
Equipment is powered, and described EOC equipment can be also that EOC Node station is powered by coaxial cable.
When EOC equipment does EOC Node station, directly receiver can be connected to by netting twine, it is possible to first pass through the network equipment
Again by light mouth or electricity mouth and receiver communication.
As in figure 2 it is shown, the signal on described coaxial cable passes sequentially through protection module, filtering isolation module, signal amplification
Module, coding/decoding module realize signal transmission, and described filtering isolation module goes interference for filtering, and described signal amplification module is used
It is provided with digital simulation transducer, for right between the long-distance transmissions of signal, described signal amplification module and coding/decoding module
Analogue signal and the mutual conversion of digital signal, described coding/decoding module is for the encoding and decoding to digital signal.Coaxial cable
Transfer rate can reach gigabit, and transmission range can reach more than 3km.
Protection module, is used for coaxial cable is carried out ESD(electrostatic defending), burst of pulses and the relevant guarantor of lightning surge
Protect, in case cable machinery damages or operation exception.Battery filter module, is provided with this equipment of battery filter module at board
It is provided with special power supply to power, by power supply and Signal averaging, is sent to the service of connection devices by coaxial cable, the power supply mistake of the service of connection devices
By power supply and Signal separator out, power supply achieves a butt joint the power supply of equipment filter module；This equipment can be EOC Node station, and docking sets
Standby can be EOC equipment, i.e. the power supply of EOC Node station and Signal averaging transmitted by coaxial cable after through the electricity of EOC equipment
Source filtering module is that EOC equipment is powered；Otherwise, this equipment can be EOC equipment, and the service of connection devices can be that EOC Node station, i.e. EOC set
Standby power supply and Signal averaging transmitted by coaxial cable after through the battery filter module of EOC Node station be EOC Node station
Power supply.Filtering isolation module, the signal isolation coupling after filtering transmitted by coaxial cable processes, and it act as filtering and goes to do
Disturb, the DC component on isolation coaxial cable, obtain the signal level that rear end equipment is able to receive that, mating protection module pair simultaneously
Reception circuit below plays corresponding protective effect.Signal amplification module, amplifies the signal of transmission over coaxial cable；If will
Signal transfers out, and amplifies signal and is conducive to long-distance transmissions；If reception signal, must amplify through coaxial cable transmission attenuation
After signal, then send rear end to.Digital simulation transducer it is provided with, for mould between signal amplification module and coding/decoding module
Intend the mutual conversion of signal and digital signal.Coding/decoding module is for the encoding and decoding to digital signal.
Described receiver is switch or server or the central apparatus of charged mouth or the central apparatus of band light mouth.EOC saves
The network mouth of some machine, it is possible to achieve with the interconnection of switch, server and optical, electrical transmission equipment etc..Described electricity mouth is transmission
Speed reaches 100,000,000, the network interface of gigabit even more two-forty, and transmission medium is netting twine；The transfer rate of described light mouth is 100,000,000, thousand
Million, 2.5G, 10G even more two-forty, transmission medium is optical fiber, and transmission range is at least up to 80 kilometers.
For EOC node electromechanics mouth (fax is defeated) or the selection of light mouth (optical transport), select according to transmission range.If
The next communication equipment of EOC Node station distance more than 100m, then uses optical transport；If the next communication of EOC Node station distance sets
Standby within 100m, then use fax defeated.
