Backlight circuit 4 comprises triode Q3, LED 1 and the resistance R 5 of above-mentioned again rectification circuit DB1 two outputs of polyphone; Wherein the base stage of triode Q3 is connected with the positive pole of rectification circuit DB1 through resistance R 4; And receive the signal controlling that output end of microprocessor 03 is sent; The collector electrode of this triode Q3 and above-mentioned LED 1 and resistance R 5 polyphones, and its emitter is connected with ground wire.Wherein resistance R 5 is carried out current limliting to LED 1 in this circuit.When there is arbitrary signal to be input in the process in the microprocessor through key circuit 8; The output 03 output high level of microprocessor; Triode Q3 conducting, LED 1 have electric current to flow through, and LED 1 is luminous, if when key circuit has no signal to be input to microprocessor in Preset Time; Output 03 output low level of microprocessor, triode Q3 by, LED 1 no current flows through and extinguish
Charging circuit 5 comprises the resistance R 6 at rectification circuit DB1 two outputs connected in series, diode D4 and rechargeable battery BT1, and wherein rechargeable battery BT1 is anodal is connected with the feeder ear of microprocessor.Resistance R 6 is charging current effects of limit battery, and diode D4 prevents that battery can not produce the electric current backflow phenomenon when having the input power supply.The power supply of battery BT1 offers microcontroller circuit, and this battery BT1 adopts Ni-MH battery, and this battery-powered time is long, working stability.
Little processing in little place circuit among the present invention adopts existing various chips to realize in addition, for example 8 of antelope machine chip FPRSPL081A; Mode of operation after it is powered on by clock source, electrify restoration circuit, the chip detection oneself of periphery
Drive demonstration by LED or LCD in the display circuit, its adopts dot matrix way or segment encode mode, and shows required field by the com port and the control of SEG mouth of microprocessor,
Button inputting circuits adopts a plurality of button setting operations in addition, is convenient to operator's operation.
Detailed above explanation the circuit structure of Circuits System of preset output type timer of the present invention, specify the course of work of preset output type timer below with this Circuits System.
One, in microcontroller circuit, preestablished fixedly timing time module, wherein have two groups of modules at least, and module that should set time length is corresponding one by one with the button that corresponding key is provided with end with set time length;
Two, through button the cryptoguard module input correct password of end in microprocessor is set, and selects after the corresponding fixedly timing time module, microprocessor is carried out fixedly timing time module;
Three, control timer provides power supply to load in the module process of execution set time length, and the predefined timer operating time finishes in the module of set time length, and the microprocessor control timer quits work.
Further explanation; The module that at least two above-mentioned groups have set time length is exactly to have stipulated the fixing timer work timing program of available machine time every day; For example: on microprocessor, store respectively in advance loose module, general module, strict module, winter vacation module and summer vacation module; Fixing respectively this timer of these modules can be at 16:00-20:00 of every day, 17:00-19:00,17:30-18:30; 9:00-11:00 and 15:00-20:00,8:00-10:00 and 14:00-19:00 start.Set different fixed timing time module like this and just can make the user use above-mentioned timer convenient flexibly, simultaneously these fixedly timing time module and button the button of end to be set corresponding one by one also be the operation that makes things convenient for the user.
Preferred employing initialization password default is provided with in the cryptoguard module of above-mentioned employing; And can revise this password default to provide this cryptoguard program stronger defencive function; This modification process is at first imported password to microprocessor through the keyboard to set up end; Treat to point out user's at least twice input same new password after the microprocessor affirmation correctly; Microprocessor will be accepted the password of this new modification like this, defines the user who uses this preset output type timer, reaches the restriction teenager and uses the recreational electronic device purpose of service time.If accidentally the password that sets is forgotten certainly; Then can timer be resetted through the reset key that is arranged on this preset output type timer; Cryptoguard module recovery in this timer is to the initial default password setting; This reset key is preferably protected, prevents accidentally this preset output type timer to be resetted.
If but after microprocessor input password, have no input signal to get into microprocessor through key circuit 8 in the given time at this; The microprocessor control timer is withdrawn into the state that requires the input password automatically so, and the above-mentioned scheduled time is preferably 10 seconds.The user uses this formula timer night for ease simultaneously; In case the user uses keyboard that timer is operated; The backlight circuit 4 of display is opened; And after Preset Time in again the timer keyboard is not operated, microprocessor cuts out backlight circuit 4 so, preferred 10 seconds of above-mentioned Preset Time.
Need to prove in addition when microprocessor closes to an end operation preset output type timer before step 3; Time remains behind certain threshold values microprocessor and can will close whole timer in the given time through control prompting sound circuit 3 prompting user microprocessors, stops to power to the load.Prompting sound circuit 3 closes to an end through the predetermined interval alarm sound attention program of three groups at least; Preferred three groups, this alarm sound sends through the buzzer LS1 in the said prompting sound circuit 3, for example; Time residue in program three minutes, two minutes and one minute difference alarm; Wherein can be when the time remain three minutes, the buzzer LS1 in the prompting sound circuit 3 rings and stopped 3 seconds in 1 second, rings 3 times continuously; In the time of two minutes, the buzzer LS1 in the prompting sound circuit 3 rings and stopped 2 seconds in 1 second, rings 4 times continuously in the time residue; In the time of one minute, the buzzer LS1 in the prompting sound circuit 3 rings and stopped 1 second in 1 second, rings 5 times continuously in the time residue.Certainly, this type of alarm is preferred mode, also can make up through other alarm sound and point out the user.
Through adopting above-mentioned technical scheme; The invention provides a kind of preset output type timer that can make things convenient for the operating time that the user sets timer; This timer also has the cryptoguard module and makes this timer have the function of anti-addiction simultaneously, the invention also discloses the method for work of the anti-addiction of this preset output type timer simultaneously.
Protection scope of the present invention is not limited to the embodiment of above-mentioned specification in addition, as long as but the combination of satisfying claim technical scheme of the present invention just fallen in the middle of protection scope of the present invention.
