Abstract
The invention relates to an electric communication device with a wave trapper. The electric communication device comprises a signal transmission line. The electric communication device is characterized in that the wave trapper is connected with the signal transmission line in series. The antijamming capability of the electric carrier communication system can be effectively improved by virtue of the combination of a wave trapper principle and an electric carrier modulator-demodulator.
Description
Technical field
The present invention relates to the power communication field, relate in particular to a kind of power communication device of trap.
Background technology
Power line carrier, PLC is most convenient, most economical network communication mode the most efficiently, need not rewiring and fast obtains the cloth net mode of express network, more and more is widely used.Yet what the power carrier delivery quality was had the greatest impact is the various reactors that in power circuit, are connected in series; Particularly " access type instrument transformer "; All can produce very strong interference with electric ballast formula fluorescent lamp etc. in big motor, the household electrical appliance; They produce frequency spectrum wide, noise amplitudes is big, makes power line carrier, PLC signal attenuation serious.Therefore to make power line carrier, PLC stable, at a high speed, must manage the employing measure, improve the antijamming capability of power carrier communication system.
Summary of the invention
For addressing the above problem, the present invention provides a kind of power communication device of trap.
For achieving the above object, the technical scheme that the present invention adopts is: a kind of power communication device with trap, comprise signal transmssion line, and it is characterized in that: trap of series connection on signal transmssion line.
First preferred version of the present invention is that described trap is a tuning circuit.
Second preferred version of the present invention is that described tuning circuit is an inductance coil, an electric capacity, and above-mentioned inductance coil is parallelly connected with electric capacity.
The present invention combines the trap principle with power carrier modem, can effectively improve the antijamming capability of power carrier communication system.
Technical advantage of the present invention is: the trap principle is combined with power carrier modem, can effectively improve the antijamming capability of power carrier communication system.
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Description of drawings
Fig. 1 is the present embodiment module map.
Embodiment
With reference to figure 1, a kind of power communication device with trap comprises the signal transmssion line trap of on signal transmssion line, connecting.Trap is a tuning circuit.Tuning circuit is an inductance coil, an electric capacity, and inductance coil is parallelly connected with electric capacity.
The resonance of inductance and electric capacity is near carrier wave high-frequency signal f0, and the high-frequency signal that stops power consumption equipment to produce passes through.And the voltage signal of common 220V, 50HZ can normally pass through.According to different high-frequency signals, can adjust the parameter of f0.
The present invention is not limited only to the protection range shown in the foregoing description, and all are based on the invention thought of present embodiment, all in protection scope of the present invention.
