Abstract
The utility model provides a system using ground wires for data transmission, which comprises two communication ends. Each communication end includes a modem and a signal coupler connected with each other, the signal coupler is mounted on the corresponding ground wire. The ground wires are communicated with each other, while two ends of each ground wire are grounded. The system adopts the ground wires as transmission media, thereby greatly increasing communication rate.
Description
Technical field
The utility model relates to a kind of data transmission system, relates in particular to a kind of system that carries out transfer of data by ground wire.
Background technology
The communication technology in the market mainly is power line communication technology (Power Line Communication), normally with the power distribution network low-voltage circuit as transmission medium, but disturbing factor is a lot of in the transmission of power line, make effectiveness reduce greatly, for improving efficiency of transmission, we communicate as transmission medium with pure ground wire.Improve the communication success rate greatly by specific ground line communication technology.
This invention is with product power line wideband transmit technology ripe and that extensively promote is very similar in the market.Power line wideband transmit technology (Power Line Communication) is to utilize low pressure 220V cable or middle pressure 10KV cable transmission data signal, and speed is from 14M, 45M to 200M even higher.But disturbing factor is a lot of in the transmission of power line, makes signal transmission rate not reach desirable effect.
Summary of the invention
Main purpose of the present utility model is to provide a kind of and carries out the system of transfer of data by ground wire, as transmission medium, makes that traffic rate has obtained improving greatly with ground wire.
Compared with prior art, the utility model provides a kind of and has carried out the system of transfer of data by ground wire, comprises two communication terminals, wherein:
Described communication terminal comprises interconnective modulator-demodulator and signal coupler, and this signal coupler is installed on the ground wire;
The mutual UNICOM of described ground wire, and two-terminal-grounding.
During enforcement, described signal coupler comprises the EMC magnet ring.
During enforcement, described modulator-demodulator is a PLC modulation module.
Compared with prior art, described in the utility modelly carry out the system of transfer of data, have the following advantages by ground wire:
1, simple and easy to use, solved traditional problems such as power line interference, optimize the signals collecting quality;
2, networking structure is flexible, and the network node that increases newly of correspondence does not influence existing network infrastructure fast;
3, use signal coupler to play and do not have the effect that electrically contacts, isolates.
Description of drawings
Fig. 1 is the structure chart of an embodiment of the system that carries out transfer of data by ground wire described in the utility model.
Embodiment
The utility model provides a kind of and has carried out the system of transfer of data by ground wire, with technical to by ground wire communication of power line transmission (PLC) technology transplant of independent research, as transmission medium, makes that traffic rate has obtained improving greatly with ground wire.
Described in the utility modelly carry out the system of transfer of data, comprise two communication terminals by ground wire, wherein:
Described communication terminal comprises interconnective modulator-demodulator and signal coupler, and this signal coupler is installed on the ground wire;
The mutual UNICOM of described ground wire, and two-terminal-grounding.
In the utility model, ground wire needs the ground wire two-terminal-grounding as the transmission medium of whole system, and the ground wire of the communications that is useful on is UNICOM mutually, and the centre can not have opens circuit.
Described signal coupler can comprise special-purpose or general EMC magnet ring on the market.
Described modulator-demodulator is used for the modulation and demodulation of signal, during enforcement, can be PLC modulation module.
In practical operation, as shown in Figure 1, modulator-demodulator is installed at signal decanting point (A point), digital signal is through being transferred on the ground wire by signal coupler after the ovennodulation.During installation signal coupler encircled and be arranged on the ground wire.Signal coupler connects in mode shown in Figure 1, and digital signal is outwards transmitted by ground wire.The interference that the ground wire transmission is subjected to is very little, at ground wire far-end B point signal coupler is installed, and at signal acceptance point (B point) modulator-demodulator is installed.The signal coupler received signal also modulates digital signal by modulator-demodulator, thereby finishes the communication that the A point is ordered to B.In like manner, also can realize the communication that the B point is ordered to A.
The system that carries out transfer of data by ground wire described in the utility model compared with prior art has the following advantages:
1, simple and easy to use, solved traditional problems such as power line interference, optimize the signals collecting quality;
2, networking structure is flexible, and the network node that increases newly of correspondence does not affect existing network infrastructure fast;
3, use signal coupler to play and do not have the effect that electrically contacts, isolates.
More than explanation is just illustrative for the utility model; and it is nonrestrictive; those of ordinary skills understand; in the situation that does not break away from the spirit and scope that claims limit; can make many modifications, variation or equivalence, but all will fall in the protection domain of the present utility model.
