Description
Technical field
The utility model relates to a kind of telechirics, specifically a kind of SCM Based remote control fan system.
Background technique
Traditional electrical fan many employings machinery type controls, and function is few, and noise is large, and the wind speed change of each shelves greatly.Along with the development of science and technology and the raising of people's living standard, household electronic products trends towards automation, intelligent, environmental protection and hommization, make to be occurred by micro-processor controlled Intelligent electric fan, along with the development of electronics manufacturing, society is more and more higher to the requirement of productivity, every profession and trade all needs efficiently superior, the equipment of high reliability meets the demands, as the old-fashioned household electrical appliances of one, electric fan has low price, put conveniently, the features such as volume is light and handy, due to the restriction of most of household consumption level, electric fan is as a member of ripe household electric appliances, still commercioganic most of share can be accounted in small and medium-sized cities and in a period of time in the future of rural area, but electric fan function is simple, intelligentized requirement can not be met.
Model utility content
The purpose of this utility model is to provide a kind of simple, reliable, cheap SCM Based remote control fan system, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technological scheme:
A kind of SCM Based remote control fan system, comprise single-chip microcomputer U1, key-press module, infrared transmission module and single-chip microcomputer U2, described single-chip microcomputer U1 connects key-press module and infrared transmission module respectively, and described single-chip microcomputer U2 connects infrared receiving module and motor control module respectively.
As further program of the utility model: described single-chip microcomputer U1 and single-chip microcomputer U2 model are AT89C51.
As the utility model further scheme: described infrared receiving module adopts infrared receiver chip I R1838.
Compared with prior art, the beneficial effects of the utility model are: the utility model make use of the infrared control function of single-chip microcomputer, again design has been carried out to the control structure of electric fan, make people just short distance can control electric fan within the scope of distance electric fan 10m, make people need not walk close to electric fan can regulate and control the wind speed of electric fan, simple, reliable, convenient, low cost has wide market prospects.
Accompanying drawing explanation
Fig. 1 is the circuit structure block diagram of SCM Based remote control fan system;

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1 ~ 3, in the utility model embodiment, a kind of SCM Based remote control fan system, comprise single-chip microcomputer U1, key-press module, infrared transmission module and single-chip microcomputer U2, single-chip microcomputer U1 connects key-press module and infrared transmission module respectively, and single-chip microcomputer U2 connects infrared receiving module and motor control module respectively.
Single-chip microcomputer U1 and single-chip microcomputer U2 model are AT89C51.
Infrared receiving module adopts infrared receiver chip I R1838.
Working principle of the present utility model is: refer to Fig. 2, at the right half part of single-chip microcomputer U1, being connected to 4 buttons is S2 respectively, S3, S4, S5 is connected with 0 to No. 3 ports of the P0 mouth of single-chip microcomputer, P0 mouth is when being used as input, pull-up resistor must be connected to, minimum systematic module and infrared emission part in the left-half of single-chip microcomputer, the information code of remote controller interrupts generation 40 kHz infrared rays square signal by the timer 1 of AT89C51 single-chip microcomputer, exported by P3.5 mouth, amplify through triode VT1, sent by infrared emission tube D1, the size changing resistance R2 can change transmitting range.
Refer to Fig. 3, the left-half of single-chip microcomputer is infrared receiver chip I R1838, its pin one is for exporting, and pin two, 3 is the input of Power supply and grounding respectively, and supply voltage is 5 V, reset function and the start and stop of what the minimum system of the single-chip microcomputer of left-half completed is single-chip microcomputer, right half part circuit is made up of a DAC0808 chip, and this chip power-consumption is low, exports and is connected with an amplifier, by voltage being added in after amplification the two ends of direct current generator, thus drive the work of motor M.
