Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1～4, in this utility model embodiment, a kind of intelligent domestic system based on radio-frequency technique, including single-chip microcomputer U1, wireless sending module, button and multiple object, each object all includes wireless receiving module and the load circuit being connected to single-chip microcomputer, and described single-chip microcomputer U1 connects wireless sending module and button respectively；Described wireless sending module uses 8 bit address codes and the PT2262 chip of 4 bit data codes, and the 1st～8 feet of PT2262 chip are corresponding with P1.0～P1.7 of single-chip microcomputer U1 respectively to be connected；Described wireless receiving module uses chip PT2272-M4 or chip PT2272-L4；Described object also includes the load circuit being directly connected to wireless receiving module；Described load circuit uses Control.
Operation principle of the present utility model is: first passes through button and determines the address match cognization coding of object to be operated, the state of a certain object of remote control it is switched to after pressing, single-chip microcomputer U1 produces with address code information and the coded pulse signal of controlled state information, then is launched by this signal by wireless sending module.
The coded pulse signal that wireless receiving module will receive, carry out coded address coupling by single-chip microcomputer to confirm, it is confirmed whether as this remote control reception end coded address, single-chip microcomputer produces corresponding output signal, output signal goes to control load circuit, it is achieved the functions such as receiving terminal brightness adjustment control, speed regulating control, on-off control.
Refer to Fig. 2, wireless sending module uses 8 bit address codes and the PT2262 chip of 4 bit data codes, 1st～8 feet of PT2262 chip are corresponding with P1.0～P1.7 of single-chip microcomputer U1 respectively to be connected, this circuit has wider operating voltage range 3-12V, when change in voltage, tranmitting frequency is basically unchanged, and the supporting receiver module of transtation mission circuit just can stably receive without adjusting.When voltage is 3V, transmission range about 20 ~ 5O rice, launch power less；When voltage is 5V, transmission range about 100-200 rice；When voltage is 9V, transmission range about 300-500 rice；When voltage is 12V, for optimum operating voltage, having preferable launching effect, emission current about 60 milliamperes, transmission range, up to 700-800 rice, launches power about 500mW.When voltage is more than 12V, power consumption increases, and ERP no longer significantly improves.
Button is divided into remotely-controlled object switch key and function control key, remotely-controlled object switch key mainly controls the address code pin of PT2262 chip by button and single-chip microcomputer U1, it is allowed to corresponding with the receiving terminal chip of different modes welding, thus reaches to control the purpose of different remotely-controlled object；The numeric data code of function control key correspondence transmitter module, thus control the various functions of different loads circuit, the load circuit common functions key of different receiving terminals, interference will not be produced, as shown in Figure 3.
This wireless receiving module can have two kinds of selections according to practical situation difference, if load circuit need to be controlled with single-chip microcomputer, then use suffix be tetra-non-locks of M4() PT2272 decoding chip (PT2272-M4)；If directly driving relay to be controlled, then use L4(tetra-latch) chip (PT2272-L4).PT2272 running voltage is 5V, wherein A0 ~ A7 is address pins, for carrying out geocoding, can be set to 0,1, f(unsettled), fix when welding, but the chip address pin welding manner of different receiving terminals is different, being easy to the identification of remote-control transmitting end, when receiving terminal PT2272 is consistent with the PT2262 address that transmitting terminal single-chip microcomputer is put, this receiving terminal will be remotely controlled by expression, chip decoding effort, does not decodes.D0-D3 is data pins, and when address code is consistent with PT2262, the high level that data pins output is corresponding with PT2262 data terminal, latch-type only could be changed when receiving next data.DIN is data signal input, from receiver module outfan.OSC1, OSC2 are respectively the input and output side of oscillation resistance, and outer meeting resistance determines frequency of oscillation.VT effectively confirms end for decoding, and high level is effective, connects a light emitting diode for detecting whether to receive useful signal, and the circuit theory diagrams of wireless receiving module are as shown in Figure 4.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this utility model in other specific forms.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes fallen in the implication of equivalency and scope of claim included in this utility model.Should not be considered as limiting involved claim by any reference in claim.
In addition, it is to be understood that, although this specification is been described by according to embodiment, but the most each embodiment only comprises an independent technical scheme, this narrating mode of description is only for clarity sake, description should can also be formed, through appropriately combined, other embodiments that it will be appreciated by those skilled in the art that as an entirety, the technical scheme in each embodiment by those skilled in the art.
