Technical field
The utility model relates to a kind of digital timing control circuit, and the electronics that is specially adapted to send different bright intensity by the adjusting of circuit voltage is flutterred the digital timing control circuit that fly device uses.
Background technology
Timing control circuit refers to summation of carrying out certain software and hardware that specifically 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, on market, there is the E-flytrap of many styles, wherein there is photo-induction and kill the E-flytrap of function and by the light sending, 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 and have poor effect by day compared with the light of low-light (level), having limited the usable range that electronics is flutterred fly device.
Summary of the invention
In view of above-mentioned the deficiencies in the prior art, the utility model provides a kind of and has been reached and regulated the electronics of bright intensity to flutter the digital timing control circuit that fly device uses by voltage-regulation.
The technical scheme that the utility model taked is to achieve these goals: 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, the collector of the voltage stabilizing chip U1 of separately leading up to 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, according to the timing controlled of the utility model design proposal, adhesive by triode pilot relay makes circuit export controlled DC voltage, 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 fly device, to adapt to the brightness of different natural lights, reach the object of saving the energy, have power failure memory function, in case of having a power failure, original parameter arranging can be kept in internal memory simultaneously.
The digital timing control circuit that the utility model proposes is saves energy greatly not only, has also improved largely stability and the reliability of system.
