Abstract

The utility model relates to a universal infrared remote controlled automatic device for opening and closing a curtain, which makes use of any key of an infrared remote controller of any domestic electric appliance to control the opening and the closure of the curtain into midway arbitrary point stop. The utility model adopts infrared coded pulse which is emitted by an infrared remote controller of any domestic electric appliance to provide count pulse fro a digital operational circuit after receiving amplification and time delay wave filtering. The pulse is only used for counting for a digital circuit, can not be limited and influenced by codes. After the digital operational circuit accepts count pulse once, the digital operational circuit is combined with state information to calculate driving instruction. After the driving circuit accepts the driving instruction, a loading motor is driven for positive rotation, back rotation, or stop. Then, the automatic opening, the automatic closure, or the midway arbitrary point stop of the curtain can be realized.

Description

The universal infrared control automatic curtain machine that shakes

The utility model relates to a kind of device that can shake the automatic folding of control control curtain.

At present, known window curtain driving mechanism all is manual, has occurred several control window curtain driving mechanisms that shake in recent years, as the patent No. is: the ZL95210476.8 automatic curtain machine, not only can only use special-purpose remote controller, and circuit adopts expensive infrared ray coder and decoder ic, cost height, operation inconvenience, known present household electrical appliances shake controlization day by day, remote controller in the family is more and more, selects to use corresponding remote controller to become a blemish in an otherwise perfect thing, bothersome thing nothing but again.

The purpose of this utility model provides a kind of any key of existing any infrared ray remote controller that can utilize can control curtain opening, the closed or device that stops of optional position midway.

The purpose of this utility model is achieved in that adding can utilize any infrared ray to shake control in original curtain transmission device any key just can control curtain and open automatically, closed or midway the optional position stop control circuit, control circuit, when utilizing any key of pressing any infrared ray remote controller, capital emission red sage outside line analog signal encoding, receiving unit in control circuit receives and amplifies, export a string coded pulse, count pulse as digital operational circuit, limit in this influence of not encoded, only count the number of times that pulse arrives, digital operational circuit according to its count pulse that provides in conjunction with unlatching, the status information that closed limit switch provides calculates and drives instruction, the driving load can connect motor just to be changeed, the counter-rotating or stop, realizing the unlatching of curtain by transmission mechanism, closed or midway the optional position stop.It specifically constitutes: connect combination by control circuit, motor, transmission device, control circuit is electrically connected the analog to digital conversion circuit IC of the output of filtering wave by prolonging time circuit and digital operational circuit by the output that receives amplifying circuit with the input of filtering wave by prolonging time circuit ₂Input be electrically connected the output of analog to digital conversion circuit and bistable state A ₁Input be electrically connected the bistable state A on the output of status information feedback circuit in the digital operational circuit ₂Input be electrically connected the bistable state A in the digital circuit ₁, A ₂Output and digital operational circuit in door B ₁, B ₂Be electrically connected, with door B ₁, B ₂Output be electrically connected with the input of drive circuit, the output of drive circuit is electrically connected with motor.

The utility model does not need the special configuration remote controller owing to adopt above measure, and circuit adopts inexpensive digital circuit, has saved expensive coding-decoding circuit, and the cost of circuit reduces greatly, uses operation very convenient yet.

Description of drawings

Fig. 1 electrical schematic diagram

Fig. 2 functional-block diagram.

Among Fig. 1, IC ₁Be the general reception head of infrared ray, IC ₂Be 555 time base circuits.IC ₃Be 7805, A ₁, A ₂Be CD4013, B ₁, B ₂Be 74LS08, m is the three-phase reversible motor, K ₁, K ₂Be spacing reversing switch, J ₁, J ₂Be miniature relay.

Function with each integrated circuit is introduced at first earlier.

IC ₁Be integrated infrared receiving terminal, it mainly is that the infrared ray that receives any remote controller amplifies.

IC ₂Be 555 time base circuits, its function is to have negative pulse to do the time spent when 2 pin, and its 3 pin upset becomes the square wave positive pulse by low level, through R ₆, R ₄Time-delay back 3 pin recover low level, are the monostable working method.

IC37805 is 3 end mu balanced circuits, and it can bring the burning voltage of 5V to circuit, to satisfy the reliability of circuit working.

A ₁, A ₂, 4013 is double D trigger, and its operation principle is, and its CP end has positive pulse to do the time spent, and its output Q, Q had both overturn once, and Q is opposite all the time with the state of Q, is the bistable state counting trigger.

B ₁, B ₂74LS08 is an AND circuit, and its operation principle is, when its input E, F were 1, its output G had both exported high level, as long as E and F end have one to be 0 o'clock or all to be 0 o'clock, output G both had been 0.

Power supply: civil power 220V exchanges through C ₈R ₉Bridge rectifier behind the resistance-capacitance depressurization supplies relay coil usefulness after the DW voltage stabilizing is 12V, surely goes out 5V voltage for front-end circuit through 7805 again.

In sum, it is as follows to describe the operation principle of circuit in detail in conjunction with Fig. 1:

Circuit supposes that curtain is in the complete opening halted state now, counting trigger A as shown in Figure 1 ₁, A ₂Output Q be 1, Q is 0, with door B ₁, B ₂Input E, F be one high and one low, output G is electronegative potential, Q ₃, Q ₄All end, circuit is not worked, and when wanting closed curtain to press any key of any remote controller, the infrared ray command signal is through a universal infrared reception IC ₁Receive and handle back (not being subjected to the restriction of frequency and coding), will export negative pulse, through Q at its output 1 pin ₁, R ₃, R ₄, Q ₂, C ₂, C ₃After the filtering wave by prolonging time network delay filtering of forming, act on monostable flipflop IC ₂2 pin enter temporary stable state, this moment, its 3 pin became high potential, triggered A ₁The counting trigger upset of forming, output Q end becomes 0, and Q becomes 1, because counting trigger A ₂CP end do not have that positive pulse effect output Q still is 1, Q still is 0, at this moment with door B ₂Input E, F the end be 0, its output G exports electronegative potential, Q ₄Still by not conducting, and with door B ₁Input E, F be 1, output G exports high potential, Q ₃Conducting, relay J ₁Adhesive, contact J _1-1Conducting, motor M is rotated, and curtain is slowly closed, waits after the complete closure, and power train is touched limit switch K ₁, make and door B ₁The high potential of output G feeds back to counting trigger A ₂CP end, A ₂The counting trigger upset of forming, output Q is 0, Q is 1, at this moment counting trigger A ₁CP end not have the effect output Q of pulse still be 0, Q still is 1, at this moment with door B ₁Input F be 0, E still is 1, thus with door B ₁Output G become 0, Q ₃End J ₁Discharge, motor stops.

In like manner,, only need press any key of any remote controller, trigger flip-flop upset A when opening curtain once more ₁, output Q and Q change, Q ₄Conducting, relay J ₂Adhesive, motor counter-rotating, wait curtain to close complete opening after, transmission system is touched limit switch K ₂, trigger flip-flop upset A ₂, output Q, Q change, Q ₄End J ₂Discharge, motor stops.

In like manner, need curtain to stop in the optional position midway, press any key of any remote controller too, A at curtain opening or closure ₁Counter overturns, and motor stops, and presses remote controller once more, and curtain will continue closure or openness.
