The Chinese invention patent application discloses a kind of electric network bridge No. 200810065021.6, comprises communication unit and coupling unit, and described communication unit one end connects network, and the other end is connected with described coupling unit, and described coupling unit also is connected with power line; Described communication unit is used for signal is changed between the form of described network and the acceptance of described coupling unit, and described coupling unit is used for transmitting signal between described communication unit and the described power line, and its received communication passage and transmission signalling channel are separate.Above-mentioned technology has been used to power line carrier communication, and it is big to have solved on power line Communication Jamming, the factors of instability.Yet, above-mentioned technology is under the situation that guarantees communication quality, and its communication distance is usually about 100 meters, if carry out longer distance High-speed data communication, because the rapid decay that signal of communication increases with distance on power line, foregoing invention just can not meet the demands.Want to carry out the high-speed data communication of longer distance, just must improve the signal to noise ratio on the signal of communication live line of force.
The utility model content
The technical problems to be solved in the utility model is, at the near defective of related transmission range in the prior art, provides a kind of signal transmission distance farther power line network bridge.
A kind of length comprises network interface, communication control unit, signal transmitting unit, signal receiving unit, power module and power line interface unit apart from power line network bridge; Described network interface one end links to each other with communication control unit, and the other end is used to connect network; The output of described communication control unit is connected with the input of signal transmitting unit and the output of signal receiving unit respectively with input; The output of described signal transmitting unit connects the power line interface unit; The input of described signal receiving unit connects the power line interface unit; Described power module is connected with communication control unit, signal transmitting unit and signal receiving unit, for it provides power supply; One end of described power line interface unit is connected with the output of signal transmitting unit and the input of signal receiving unit, and the other end links to each other with power line; Described signal transmitting unit cooperates multistage coupling unit to constitute by multi-stage superimposed amplifying unit.
The length that the utility model provides has following beneficial effect apart from power line network bridge: adopt multi-stage superimposed amplifying unit in the signal transmitting unit, thereby increased sending the multiplication factor of signal, increased transmitting power, thereby increased the high speed data transfer distance, and signal transmission effect is more stable on original basis.
Description of drawings
Fig. 1 is a kind of structural representation of growing apart from power line network bridge embodiment of the utility model;
To be that the utility model is a kind of grow apart from the formation of the signal transmitting unit of power line network bridge and the schematic diagram that signal transmitting unit is connected with control unit and power line interface unit Fig. 2.
