Narrate the operation principle of each several part below respectively.
Power circuit 1: see Fig. 1,2, closed mains switch SA1, civil power is after power transformer T step-down,, power to each relay K 1-K10 and relevant drive circuit, each road output indicator LED3-LED13 after capacitor C 1 filtering through diode VD2, VD3 full-wave rectification by secondary pair of 12V AC Windings.By providing stable 12V voltage to amplifier integrated package LM324 after the filtering once more through VD1 halfwave rectifier, C2 filtering, regulator block 7812 voltage stabilizings, C3, C4 by secondary 18V winding.Again by regulator block 7805 voltage stabilizings, diode VD4, VD5, VD6 step-down, obtain stable 3V voltage after capacitor C 6, the C7 filtering to microcomputer PIC power supply, the normally-closed contact that passes through relay K 10 is to stand-by power supply G simultaneously, and stand-by power supply G is in series by two joint rechargeable batteries.Press checkout button SB1, relay K 10 adhesives, the anodal 3V voltage that provides with civil power of battery G is provided in its transfer contact, and connect with the LED 2 of little resistance resistance R 2 and band current-limiting resistance R3, battery G passes through resistance R 2 with bigger current discharge, if this moment, LED2 was still brighter, illustrate that battery G also has electricity can continue to use.If LED2 is luminous faint, prompting should have been changed reserve battery G.During mains failure, relay K 10 is failure to actuate, and it is inoperative to press checkout button SB1, and when having prevented power failure, the battery G that detection was used for a long time, internal resistance increases is under the condition of heavy-current discharge, and end is pressed to decline to a great extent the interior set program of microcomputer is lost.F is a protective tube, and piezo-resistance RV works to absorb the power surge electric current.
Microcomputer time controller 2:
Microcomputer time controller shown in Figure 3 is No. 8 timers that the PIC series monolithic designs, by its three button SB2 function key, SB3 time adjust, SB4 divides adjustment, every road can be provided with 2 periods every day and promptly 2 open 2 and close regularly, method to set up is omitted, 8 road timer output end d1-d8 are picked out by the RB interface, when wherein having one the tunnel to reach the service time of setting, and the output high level, otherwise when reaching the shut-in time of setting, be output as zero.
In former No. 8 timers, what go here and there between resistance R 35 upper ends and VCC is a single-pole single-throw(SPST blanking switcher, during power failure, must artificial disconnect this switch, charactron be extinguished prolonging the service time of reserve battery, during incoming call, by artificial closed this switch of palpus, make charactron recover to show, very inconvenient.
Now this switch is replaced with a triode BT10 and a resistance R 33, and make the R33 left end receive 7805 outputs, just constituted automatic blanking switcher.During power failure, VT10 ends because of triode, and charactron extinguishes, and during incoming call, V10 obtains enough base currents and saturation conduction by resistance R 33, and charactron recovers to show automatically.Like this, display screen has played the effect of power supply indicator again, so has saved power supply indicator on the panel.
Among Fig. 2, light-operated and temperature control testing circuit 3:
The street lamp light-operated circuit:
12V voltage is after R5, R6 dividing potential drop, make 5 pin of amplifier piece LM324 obtain reference voltage V 5, at dark, shine that the light on the photodiode UD1 weakens gradually in the street lamp photosensitive probe, make photodiode UD1 backward resistance value increase gradually, and then make with it the voltage of getting on the resistance R 4 of series connection and the potentiometer W1, the voltage V6 that promptly is added on the same amplifier of LM324 unit 6 pin reduces gradually, when light is attenuated to when making V6＜V5, LM324 the 7th pin is a D3 output high level; Otherwise morning, at day the reverse resistance of photodiode UD1 reduced gradually, and V6 is raise gradually, and when B6＞V5, LM324 the 7th pin is the D3 output low level; Regulator potentiometer W1 or change the lighting angle of light-operated probe all can adjust the sensitivity of street lamp light-controller, makes it morning just seeing clearly when walking, and just turns off street lamp automatically.
The classroom lamp light-operated circuit:
12V voltage obtains reference voltage V 2 after R9, R10 dividing potential drop, be added on 2 pin of amplifier piece LM324, and daytime is when the light deepening, the reverse resistance of photodiode UD2 that is loaded in the photosensitive probe increases, the 3 pin current potential V3 of amplifier LM324 are raise, and when V3＞V2,1 pin is a D1 output high level; Otherwise when daytime, light was enough bright, 1 pin was the D1 output low level; Start to control sensitivity and can or change the realization of photosensitive probe lighting angle by regulator potentiometer W2.On two photodiodes capacitor C 8, C9 in parallel can eliminate or reduce moment light and change the interference that causes.
The ceiling fan temperature control circuit:
Reference voltage V 12 on 12 pin of DM324 is obtained by resistance R 13, R14 dividing potential drop, Rt is a NTC high sensitivity temperature sensor, be connected in the outer temp probe of machine with shielding conductor, when room temperature rises to uniform temperature, because the Rt resistance reduces, when making the 13 pin current potential V13 of amplifier LM324 drop to less than V12, amplifier 14 pin are D2 output high level, otherwise, when room temperature is reduced to a certain degree, amplifier 14 pin are the D2 output low level, and ceiling fan is opened temperature and can be realized by regulator potentiometer W3.
Resistance R 7, R11, R15 are respectively the negative feedback resistor of 3 groups of amplifiers, work to stablize 3 groups of amplifier work.
Multichannel time control, light-operated, temperature control reorganization circuit 4 and actuator 5:
