Description

A kind of digital timing control circuit

Technical field

The present invention relates to a kind of digital timing control circuit, be specially adapted to flutter by the electronics that different bright intensity are sent in the adjusting of circuit voltage a kind of digital timing control circuit that the fly device uses.

Background technology

Timing control circuit refers to summation of carrying out the software and hardware that certain specific operation arranges for certain specific time.Certain specific time refers to the timing data of artificial or program setting, and certain specific operation refers to that sending certain controls data to functional module, and functional module is operated accordingly according to controlling data.

For the insect that kills flies and mosquitoes, the E-flytrap of many styles has appearred on market, wherein has photo-induction and kills the E-flytrap of function and by the light sent, mosquitos and flies is attracted, on the sticky hardboard that bonds to strong sticky stickiness and reach the effect of the insect that kills flies and mosquitoes.But at present, product is that a kind of is can use in order to take into account daytime and night, sets higher illumination, and in fact at night, does not need the light of high illumination, causes a large amount of power consumptions according to identical illumination work when work.Another kind is for saving electricity consumption, set, than the light of low-light (level), poor effect is by day arranged, having limited the usable range that electronics is flutterred the fly device.

Summary of the invention

In view of above-mentioned the deficiencies in the prior art, the invention provides and a kind ofly by voltage-regulation, reach the electronics of regulating bright intensity and flutter a kind of digital timing control circuit that the fly device uses.

The technical scheme that the present invention takes to achieve these goals is: a kind of digital timing control circuit, it is characterized in that: comprise voltage stabilizing chip U2, single chip machine controlling circuit MCU, LED display SM, supplying cell BAT, input key S, current rectifying and wave filtering circuit V, voltage stabilizing chip U1, voltage stabilizing chip U3, triode VS, relay J, the input termination 9V alternating current of described current rectifying and wave filtering circuit V, the output terminal of current rectifying and wave filtering circuit V is leaded up to voltage stabilizing chip U2 and is accessed respectively the input end of LED display SM and single chip machine controlling circuit MCU, another road is by the collector of voltage stabilizing chip U1 access triode VS, Third Road is by the actuating station of voltage stabilizing chip U3 cut-in relay J, described supplying cell BAT and three input key S access respectively single chip machine controlling circuit MCU, the output terminal of described single chip machine controlling circuit MCU connects the base stage of LED display SM and triode VS, the control end of the emitter cut-in relay J of described triode VS, described relay J output terminal output 1.2V DC voltage, the model of described single chip machine controlling circuit MCU is: STM32F050C6T6.

Obviously, the timing controlled of design proposal according to the present invention, adhesive by the triode pilot relay makes the controlled DC voltage of circuit output, realization is exported different electric signal in the different time periods, thereby reaches the bright intensity that automatic adjusting electronics is flutterred fluorescent tube in the fly device, to adapt to the brightness of different natural lights, reach the purpose of saving the energy, have simultaneously power failure memory function, if had a power failure, original parameter arranged can be kept in internal memory.

Digital timing control circuit proposed by the invention is saves energy greatly not only, has also improved largely stability and the reliability of system.
