Description
Technical field
The utility model relates to a kind of signal processing apparatus, particularly a kind of consumer far-end control signal treating apparatus.
Background technology
The far-end of consumer of the prior art is controlled and is generally all adopted the special network of arranging as transmission and processing media, control end is sent steering order from network, and controlled end receives the instruction of transmitting from network by far-end control signal treating apparatus, order opertaing device corresponding actions.Because the special network of arranging, the wiring installation amount is bigger, and the cable wiring manufacture process can influence people's operate as normal and life, so in fact this far-end control mode does not have the practical application meaning, accordingly, far-end control signal treating apparatus also just rests on the category of general imagination.
Invention constitutes
The purpose of this utility model is to overcome weak point of the prior art and provides a kind of and can be applied on the existing network, has the practical application meaning, simultaneously the fast consumer far-end control signal treating apparatus of data processing speed.
The purpose of this utility model realizes by following approach:
Consumer far-end control signal treating apparatus, comprise signaling interface, its structural feature is: also include central processing unit and modulator-demodular unit, signaling interface comprises a kind of power distribution signal sampling device, the one end is connected with power distribution, and the other end then is electrically connected with modulator-demodular unit and central processing unit in regular turn.
So just can come transfer control instruction by power distribution.After the power distribution signal sampling device receives from the steering order on the power distribution, after demodulating valid data, modulator-demodular unit delivers to central processing unit, the valid data analyzing and processing of central processing unit to receiving, and require to send control signal corresponding according to data command, corresponding operating is finished in the action of order opertaing device.
Still not a kind of existing network of power distribution, and any consumer all has connector with it, directly consumer far-end control signal treating apparatus described in the utility model is plugged between this interface and the consumer, promptly can realizes the far-end of consumer is controlled by this existing network.
The utility model can further be specially:
The power distribution signal sampling device includes electric capacity and transformer, wherein termination in the winding two ends of the former limit of transformer by electric capacity or be connected with the electrical network zero line or with the electrical network live wire in wherein one be connected, another termination ground connection, transformer secondary winding then is connected with modulator-demodular unit.
All consumers all must produce between at least two wiring (phase line and baseline) the electrical network load effect, and all be loaded with high-frequency modulation signal in every wiring, we only take a sample with pickoff signals (also can transmit) to a wiring now, and the load variations of electric terminal will be difficult to sampled signal is exerted an influence.
Here, the connected mode of electric capacity and transformer is formed a kind of high-frequency signal passage.And the ground of ground connection indication is preferably the ground of wiring board, and at this moment, the line that connects winding one termination, the former limit of transformer and power network wiring (zero line and live wire) becomes an antenna.
Also include amplifier, it is electrically connected with central processing unit.
The power distribution signal sampling device is used for from the electrical network pickoff signals and transmits to electrical network; Amplifier can be used for signal that picks up and signal to be transmitted are carried out processing and amplifying.
Modulator-demodular unit comprises chip SSC-P200, and central processing unit chip model is PIC16C62B, wherein, and 2 pin of chip SSC-P200,7 pin, 8 pin, 9 pin, 10 pin and 12 pin respectively with 26 pin of chip PIC16C62B, 21 pin, 14 pin, 15 pin, 16 pin are connected with 3 pin are corresponding.
In sum, the utility model has the following advantages compared to existing technology: can directly be applied on the existing electrical network distribution wire, owing to adopted the signal sampling device of particular design, make the load variations on the electrical network be difficult to sampled signal is exerted an influence, so have the practical application meaning, and the highest 10M that can reach of communication speed by the electrical network distribution wire, so this device data processing speed is very fast.The most important thing is, under the situation that need not other special design (as wiring etc.) and special device, only depend on this device can realize the far-end of consumer is controlled.
