Description

The supply socket of installing type computer clock

The utility model belongs to electronic technology field, relates to a kind of automatic control power supply socket.

Existing electronic clock control socket adopts the special clock integrated circuit mostly.As LM836X series, often pin is many, function singleness, and volume is big, and in the socket that is difficult to pack into, so normal on the structure what adopt is rack-and-panel connector formula or miniature instrument form, uses inconveniently, and it is unreliable to contact.

The purpose of this utility model provides a kind of easy for installation, reliable, and is accurate during control, and can set repeatedly the wall installing type clock supply socket of time.

The technical scheme that realizes above-mentioned purpose is: the utility model comprises panel, is installed on supply socket and LED display and control circuit board thereof on the panel.Feature is that the core of control circuit board adopts the monolithic computer, and it specifically is made up of monolithic computer, LED display, oscillating circuit, relay, keyboard, supply convertor and socket.LED display, keyboard, button join with the bidirectional interface of monolithic computer respectively, the control relay circuit control line then is connected to the delivery outlet of monolithic computer, and socket is connected between power supply phase line and the relay contact, the monolithic computer also has two pin external oscillation circuits, and above-mentioned each circuit all links to each other with power converting circuit.

Accompanying drawing 1 is the utility model panel construction schematic diagram.

Accompanying drawing 2 is the utility model clock control circuit plate block diagram.

Accompanying drawing 3 is the utility model clock control circuit plate circuit electrical schematic diagram.

Below in conjunction with accompanying drawing the utility model is elaborated.

LED display 13 is installed on the wall installing type electric socket panel 11 of standard with the standard socket module 12 that can change flexibly, LED display 13 is provided with

power supply indicator

1,10 o'clock figure place sign indicating numbers 2, figure place sign indicating number 3 when individual, second, point 4, tenths number 5, individual quantile sign indicating number 6, fast school button 7, school button 8, removing button 9 preset button 10 slowly.

The clock control circuit plate by monolithic computer 16 and LED display 13, keyboard 14 (by soon,

school button

7,8 slowly, remove button 9, preset button 10 and form), oscillating circuit 15, relay 17, supply convertor 18 constitute.

And monolithic computer 16 (D1) adopts the PIC16C54 integrated circuit, and it includes CPU, RAM, ROM, internal bus, monofier, reset circuit and 12 I/O mouths.5 pin Vss ground connection wherein, 14 pin Vdd connect positive source, 3 pin RTcc connect high level by pull-up resistor R1,4 pin are that resetting pin also connects high level, inner circuit of electrification reset, 15,16 pin meet oscillation circuit C4, C3 respectively to ground, meet 4MHz quartz oscillator Z1 between 15,16 pin, form the master clock double as time reference of oscillating circuit as computer with the internal amplifier of D1,12 remaining pin are to connect like this.6-12 pin (R _B0-R _B6) connect 2 (a sections), 1 (b section), 10 (c sections), 11 (d sections), 7 (e sections), 4 (f sections), 5 (g section) pin of clock display screen, 17,18,1,2 pin (R respectively by current-limiting resistance R15-R21 _A0-R _A3) connect 12,9,8,6 pin of clock display screen respectively, R2, R3, R4, R5 are connected between 9,10,11,12 pin of D1 and the positive source as pull-up resistor, usual 9,10,11,12 present high level when doing the input port, and R6, R7, R8, R9 are respectively by S1, S2, S3, S4 ground connection, because R2＞R6, R3＞R7, R4＞R8, so R5＞R9 is when any key switch of S1-S4 is pressed, the relevant pin of D1 will be low level, come query processing by CPU.A remaining mouth 13 pin (R _B7) connect the base stage of triode V1 by current-limiting resistance R10.When " opening " time regularly then, R _B7The output high level makes the V1 saturation conduction, is connected on the relay K 1 energising adhesive of V1 collector electrode, thus socket XS1 energising, regularly " pass " time then, R _B7Output low level makes V1 end shutoff, and relay K 1 discharges back normally open, the socket outage.Socket is connected between power supply phase line and the zero line by relay normally open contact.V6 is the fly-wheel diode that is connected in parallel on the relay coil, and the energy when effect is outage in the coil is avoided producing high pressure by V6 release and punctured V1.C1, C2 are connected in parallel between power supply center line and the circuit ground, voltage after V4, the V5 series connection is used to supply with relay work, voltage on the V5 is for control circuit work, C5 is the accumulation of energy filter capacitor that is connected in parallel on V4, the V5, V3 is the rectifier diode to the C5 charging, V2 is reverse bypass diode, and C6 is the step-down current limiting capacitance of string in AC power, and the R12 that is connected in parallel on the C6 discharges the discharge resistance that C6 goes up residual charge.R13, the R14 that power supply phase line end of incoming cables connects is surge current in the limiting capacitance C6 charge and discharge process and the resistance of usefulness, and L is the power supply phase line, and N is a zero-power line, and XS1 is controlled supply socket module, is used to insert controlled electric appliance.

Energized during use, charactron are with 1 second cycle glittering " 0:00 ", and this moment, socket was in off-position.Key when pressing the school (soon, school) slowly can be adjusted constantly, and " presetting " button is used for preset opening and turn-offing constantly, and " removings " button is used for removing the unlatching that has preset and turn-offs the moment, prepares for reinitializing.If the user observes " * *: * * " glittering, illustrate that this socket had stopped electricity, before " * *: * * " time, recover energising, at this moment, the open and close moment that preset in the past also is eliminated automatically, and socket is in off-position.

The utility model control circuit board core circuit adopts the monolithic computer, compact conformation, and volume is little, can be made into standard The fixed clock-controlled power socket of wall. Use safety, convenient, reliable, and have the control accuracy height, show eye-catchingly, have Telegram in reply indication and the defencive function that cuts off output after having a power failure can be set the advantages such as the multipoint switch moment in 24 hours.
