Characteristics of the present invention are to utilize a kind of system of microprocessor controls, it is being provided with outside the infrared ray module induction infrared signal, other adds a ultralow consumable electrode type and independently-powered prime sensing circuit induction infrared ray leading wave, can under holding state, close the system power supply, only receive the infrared ray leading wave of remote controller, reach the power saving effect of the ultralow power consumption of holding state by the prime sensing circuit senses.
Fig. 1 is the structure calcspar of infrared ray module;
Fig. 2 is the system embodiment schematic diagram that the present invention is used in the control curtain;
Fig. 3 is the structure calcspar of prime sensing circuit of the present invention;
Be used in the system embodiment schematic diagram of control curtain referring to the present invention shown in Figure 2.As shown in the figure, the present invention establishes by a microcontroller 2 to be main logic unit, the microcontroller power supply is given an infrared ray module 1, mat infrared ray module receives the infrared ray harmonic ringing from remote controller sent, infrared signal through solving correct frequency is sent to microcontroller, again by microcontroller 2 interpretation signal correctness, as solves and is correct infrared signal, then system enters the state of controlling, and promptly notifies motor-drive circuit 4 drive motors 5 to carry out corresponding control action; And when motor 5 rotated, microcontroller 2 was also monitored the speed of motors 5 simultaneously via Photo Interrupter 6.
In the foregoing description, the structure of this infrared ray module 1 is identical, promptly as shown in Figure 1 identical with use now, does not repeat them here.And this prime sensing circuit 3 is to be made of ultralow consumable electrode type amplifier, also can be regarded as a simple type but the infrared ray module of power consumption.
Structure calcspar referring to prime sensing circuit of the present invention shown in Figure 3.As shown in the figure, wherein prime sensing circuit 3 is established by infrared diode 31 and is received the infrared ray leading wave that remote controller sent, remove high frequency noise through low pass filter 33 again, with a ultralow consumable electrode type amplifier 33 signal is amplified then, be shaped to square-wave signal by peak detector 34 and comparator 35 again, then export microcontroller 2 to.
Wherein the amplifier 33 of ultralow consumable electrode type is sacrificed frequency range for the purpose that reaches the super low consumption electric current, thereby cause to eliminate fully the environment noise and disturb, on the other hand can not be by the infrared ray harmonic ringing that is subjected to general commercial 38kHZ, so, then must adopt ultrared frequency range to be low to moderate below several kHZ in order to use the prime sensing circuit 3 of this ball bearing made using structure.For this reason, infrared remote control signal just must be revised and reach this requirement.Therefore the signal that remote controller sent that native system adopted must be by the two circulation of infrared ray harmonic ringing of the infrared ray leading wave and a 38kHZ of a low frequency (being made as 3kHZ at this).
And in the above embodiments,, can divide into three kinds of states according to system's power consumption difference.It at first is holding state, main power consumption is at prime sensing circuit 3 under this state, and system itself is current sinking not, promptly except prime sensing circuit 3, other power supplys of system all are closed, and 2 of microcontrollers enter low power consumption mode (power consumption stream is about 1 μ A).When infrared remote control signal produces, prime sensing circuit 3 will send a triggering signal to and microcontroller 2, microcontroller 2 enters operational pattern after receiving a signal immediately, and the power supply opening of system supply infrared ray module 1 received complete infrared ray harmonic ringing, just enter monitoring state this moment.Solved if be provided with correct infrared signal in the setting-up time under this monitoring state (as 60ms), then system will revert to holding state again; Solved if any correct infrared signal, then system will enter the state of controlling, and promptly notify motor-drive circuit 4 drive motors 5 to carry out corresponding control action.Because of all power supplys beyond the microcontroller 2 control prime sensing circuits 3, thus under holding state system's current sinking not, and then reach the power saving effect of ultralow power consumption.
Wherein native system still keeps the infrared ray module 1 of present use, be in order to eliminate the influence that noise disturbs, therefore plant that infrared ray module 1 can be reconciled the infrared ray harmonic ringing of a commercialization (infrared ray of 38kHZ is tuning) but the correctness that makes microcontroller interpretation signal data, and this infrared ray module 1 can reach the purpose of multi-functional control simultaneously.Especially when prime sensing circuit 3 was triggered by noise, it is stable that system still can keep.
In addition, in the infrared ray leading wave that remote controller sent and infrared ray harmonic ringing that native system adopted, the purpose of this infrared ray leading wave is to trigger prime sensing circuit 3, causes microcontroller 2 actions and opens system power supply; Thereafter infrared ray harmonic ringing will be reconciled again through microcontroller 2 decodings by infrared ray module 1.So, whole system not only has the characteristic (power consumption of whole sensing receiver system using infrared ray only is 40 μ A) of ultralow power consumption under the holding state, even prime sensing circuit 3 is triggered 100 times in 24 hours, average power consumption stream also only increases by 1 μ A; Under the environment that highly disturbs, also needn't worry its stability simultaneously.In addition, another advantage of native system is a real-time system, does not have the delay issue of general periodic switch power-supply system.
