1, when environmental temperature is low, triode BG9 (utilizes the adaptations of this triode PN junction to temperature, make temperature inductor with it) be transferred to operational amplifier IC5 (adopting LM358 in the present embodiment) and amplify, the signal voltage of triode BG10 output is just low, this voltage and 2 of the operational amplifier IC12 that is provided with in advance, 6,9,13 and operational amplifier IC13 2, the voltage of 6 pin is compared, as greater than 4.3V less than the 4.8V 7 pin output high potential of IC13 then, this high potential makes triode BG28 conducting through resistance R 73, so Zener diode ZD10 (the voltage stabilizing value is higher) is access in the mu balanced circuit of being made up of three-terminal voltage-stabilizing ic chip 15, make higher voltage of its output output, this voltage adds to in-phase input end the 3rd pin of operational amplifier IC1 (LM358), make its conducting from the voltage of its 1st pin output through the base stage that resistance R 6 adds to triode BG1, make the BG2 conducting after the BG1 conducting again, the 24V DC voltage is through diode D1, the normally-closed contact of relay J 4, triode BG2, inductance L is given the load RL energising as heater element, and the heat that load RL sends has just offered the plant that need heat.Simultaneously, voltage on the load RL feeds back to inverting input 2 pin of operational amplifier IC1 again, compare with the voltage of its in-phase input end 3 pin, be higher than 3 pin voltages as 2 pin voltages, then its 1 pin is output as 0, and this moment, triode BG1 ended, and triode BG2 also ends, 24V DC voltage and load RL disconnect, and stop heating.After stopping heating, load RL goes up inverting input 2 pin that no-voltage feeds back to operational amplifier IC1, and its in-phase input end 3 pin have the voltage of sending here from three-terminal voltage-stabilizing ic chip 15 outputs, so the 1st pin of operational amplifier IC1 is exported high level again, triode BG1, BG2 conducting again, the 24V direct current adds to the heating wire two ends again.So repeatedly, promptly having obtained one on the heating wire pressed by three-terminal voltage-stabilizing ic chip 15 (higher) galvanic currents control, that approximate its output, to send the more lower environmental temperature of heat reply, so the plant of being heated just obtains suitable stable temperature.

The signal voltage of, triode BG10 lower as environmental temperature output is during less than 4.3V, six equal no-outputs of comparator among IC12, the IC13 then, triode BG23～BG28 all ends, at this moment just have only ZD11 to be access in the mu balanced circuit of three-terminal voltage-stabilizing integrated package and output voltage is the highest, when just environmental temperature is the coldest.

2, when environmental temperature raises, the signal voltage that triode BG9 is transferred to operational amplifier IC5 amplification, triode BG10 output is just high.This voltage is also compared with the voltage of two reverse input ends of four reverse input ends of the operational amplifier IC12 of prior setting and operational amplifier IC13, as greater than 7.6V, then 1 pin of IC12 is exported high potential, this high potential makes triode BG23 conducting through resistance R 68, so Zener diode ZD5 (the voltage stabilizing value is lower) is access in voltage-stabilizing output circuit, make lower voltage of output output of three-terminal voltage-stabilizing ic chip 15.Situation when control procedure afterwards is low with aforementioned environmental temperature is identical, still can be obtained a stable suitable temperature by the plant of heating.

By that analogy, the temperature signal voltage of triode BG10 emitter stage output height not simultaneously, among corresponding Zener diode ZD5～ZD11 one will be access in the mu balanced circuit of three-terminal voltage-stabilizing ic chip 15, make the different magnitude of voltage of its output.Therefore, the amount of heating of plant is followed the height of environmental temperature and is changed, the environmental temperature height, and the amount of heating is just low, and environmental temperature is low, and the amount of heating is just high, so plant just obtains a more stable root temperature.

3, progressive, the control of gradually moving back of temperature

In fact, natural environment is that temperature begins to rise after daybreak, As time goes on and constantly raises, begin again to reduce during to the dusk, the temperature decline of black fully back, sky is more, that is to say, be not a stationary temperature daytime, and evening neither a stationary temperature.For simulating this natural environment temperature, this controller is provided with the progressive control circuit of day temperature, and night, temperature was gradually moved back control circuit.

(1) the day temperature progressive process is (for ease of analyzing, wouldn't count the voltage stabilizing value of Zener diode ZD5～ZD11): if after relay J 2 adhesives, Zener diode ZD1, ZD2 be by short circuit, and this moment, three-terminal voltage-stabilizing ic chip 15 output voltages then were the voltage stabilizing value sums that self 5V adds diode D3～D5.

When morning at day, optical sensor VT is subjected to light and resistance decreasing, make triode BG14 conducting, 1 of NAND gate IC6 (present embodiment adopts 4011), 2 pin are electronegative potential, its 3 pin output high potential, make triode BG15 conducting through resistance R 38, timing integration block IC8 (adopting 4541 in the present embodiment) must establish the beginning timing by cable, after about 5 minutes, the 8th pin output high potential of IC8, make triode BG16 conducting through resistance R 41, by 3 among the NAND gate IC6, the flip and flop generator upset that 4 NAND gates are formed, its 10 pin output electronegative potential is delivered to 2 of 555 ic chips 7,6 pin, 3 pin of IC7 are promptly exported high potential 1, so regularly timing integration block IC10 (identical with IC8, as to adopt 4541) must establish beginning timing in 30 minutes by cable.Before timing in 30 minutes reaches, the 8 pin no-outputs of IC10, thus not conducting of triode BG19, relay J 3 not adhesives, diode ZD2 still is short-circuit condition.Because 3 pin of 555 ic chips 7 output high potential, this high potential makes triode BG20 conducting through resistance R 51, triode BG21 ends, timing integration block IC11 (same IC8, adopt 4541) dead electricity and quitting work, its 8 pin output becomes electronegative potential by high potential, triode BG22 is become by conducting and ends, relay J 2 becomes release by original adhesive, Zener diode ZD1 is access in sampling circuit of pressure-stabilizing, make the rise voltage stabilizing value of a Zener diode ZD1 of three-terminal voltage-stabilizing ic chip 15 output voltages, also just the risen voltage stabilizing value of a Zener diode ZD1 of the voltage on the load RL is planted the material temperature that therefore also just raise.

After about 30 minutes of daybreak, just timing integration block IC10 timing is after 30 minutes, its 8 pin output high potential makes triode BG19 conducting through resistance R 50, so relay J 3 adhesives, its normally-closed contact disconnects, Zener diode ZD2 is access in sampling circuit of pressure-stabilizing, raise the again voltage stabilizing value of a Zener diode ZD2 of three-terminal voltage-stabilizing ic chip 15 output voltages, and load RL goes up the also corresponding rising of voltage that obtains as a result, plant material also with regard to the temperature that raise again, finish the day temperature progressive process.

(2) evening, temperature was gradually moved back process: when it is just black, it is big that the unglazed photograph of optical sensor VT and resistance become, triode BG14 is become by the conducting on daytime and ends, 1,2 pin of a NAND gate IC6-1 among the IC6 become high potential by electronegative potential, and its 3 pin becomes electronegative potential, through resistance R 38 triode BG15 are ended, timing integration block IC8 dead electricity and not working, its 8 pin becomes electronegative potential by high potential, so triode BG16 ends, the flip and flop generator input reverts to high potential.When the output of NAND gate IC6-1 becomes electronegative potential, NAND gate IC6-2 exports high potential, make triode BG17 conducting through resistance R 44, timing integration block IC9 must establish the beginning timing by cable, about 5 minutes, its 8 pin output high potential, make triode BG18 conducting through resistance R 45, the input of NAND gate IC6-4 is electronegative potential through triode BG18 to ground, the flip and flop generator upset, the output high potential, and deliver to 2 of 555 ic chips 7,6 pin, make its 3 pin be output as electronegative potential, timing integration block IC10 dead electricity and not working, its 8 pin becomes electronegative potential by high potential, and triode BG19 ends, relay J 3 becomes release by adhesive, and the normally-closed contact of relay J 3 is with Zener diode ZD2 short circuit.At this moment, three-terminal voltage-stabilizing integrated package output voltage is that the output voltage (closing of the voltage of self 5V+D3+D4+D5+ZD1+ZD2) on daytime deducts by the voltage stabilizing value of the Zener diode ZD2 of short circuit.Plant the material temperature and promptly reduced a part.Simultaneously, when 3 pin of 555 ic chips 7 are output as electronegative potential, through resistance R 51 triode BG20 is ended, triode BG21 conducting, timing integration block IC11 must establish beginning work timing by cable, after about 1 hour, 8 pin of IC11 become high potential 1 by electronegative potential, make triode BG22 conducting through resistance R 55, relay J 2 adhesives, Zener diode ZD1 is by short circuit, so, the voltage of three end integrated voltage stabilizer IC15 output deducts the voltage stabilizing value of a Zener diode ZD1 again, and the voltage on the load RL further reduces, plant the material temperature and also further reduce, thereby realized gradually moving back of temperature at night.

3, holding circuit

Comprising that overcurrent protection, environmental temperature raise prevented to heat protection and temperature sensor fails protection.

(1) overcurrent protection:

In the controller work, cause operating current to surpass normal value (and the probability of heating wire short circuit is almost nil) for a certain reason, voltage will increase on the resistance R 11, make triode BG3 conducting, and the input of NAND gate IC3 (adopting 4011 in the present embodiment) is electronegative potential through triode BG3 to ground, the flip and flop generator upset, IC3 exports high potential, makes triode BG4 conducting through resistance R 10, relay J 4 adhesives, the normally-closed contact of J4 disconnects, and cuts off the power supply to load RL.

(2) environmental temperature raises and prevented to heat protection:

Along with the temperature rise, fine temperature raises more, plants the material temperature in the basin of need not heating and also can reach about 24 degree, heats as switching on this moment again, and the too high danger of burning plant to death of the plant temperature of causing is arranged.For this reason, utilize environmental temperature to raise after, the characteristics that the voltage of triode BG10 emitter stage output also can raise add to the in-phase input end of operational amplifier IC5-2 to this voltage through resistance R 20, make it to compare with the voltage of inverting input.Because of the inverting input voltage of operational amplifier IC5-2 is provided by 8V Zener diode ZD4, so in-phase input end voltage is in case surpass 8V, IC5-2 exports high potential, add to an input among the NAND gate IC3-3 through resistance R 29, make its output electronegative potential, through resistance R 30 triode BG11 is ended, triode BG12 conducting, timing integration block IC14 (present embodiment adopts 4541) must establish the beginning timing by cable, its 8 pin output high potential makes triode BG13 conducting through resistance R 34 after about 5 seconds, and the input of IC3-1 is an electronegative potential through triode BG13 ground connection, the flip and flop generator upset, the output high potential makes triode BG4 conducting through resistance R 10, relay J 4 adhesives, cut off load RL power supply, guaranteeing to plant the material temperature can be not too high.

(3) temperature sensor fails protection:

Temperature sensor fails comprises short circuit sensor and two kinds of situations of open circuit.

A, when triode BG9 short circuit; the inverting input of operational amplifier IC5-1 is equivalent to be connected on the ground; its output is then exported the high voltage of 10V; triode BG10 emitter stage is also with output HIGH voltage; this high voltage adds to the in-phase input end of operational amplifier IC5-2 through resistance R 20; more much higher than the 8V on its inverting input; so IC5-2 output high potential; this situation is identical with the situation of " environmental temperature raises and prevented the protection of heating "; finally cause relay J4 adhesive after 5 seconds, cut off power supply load RL.

B, when triode BG9 opens a way; the inverting input that is equivalent to operational amplifier IC5-1 is connected on the 12V power supply; at this moment IC5-1 output electronegative potential; the emitter stage of triode BG10 also will be exported electronegative potential; can force triode BG6 to end through resistance R 23; triode BG7 conducting; timing integration block IC4 must establish the beginning timing by cable; its 8 pin output high potential after 5 seconds; make triode BG8 conducting through resistance R 27; to ground, this is identical with " overcurrent protection " situation, does not give unnecessary details through triode BG8 for the input of IC3-1.

4, the automatic conversion that has a power failure, sends a telegram here

The stand-by power supply part is made up of coil, Zener diode ZD3 and the accumulator of photoelectrical coupler IC2, triode BG5, relay J 1.

(1) when mains failure, the diode cathode of photoelectrical coupler IC2 is an electronegative potential, accumulator diode cathode from photoelectrical coupler IC2 after resistance R 12, Zener diode ZD3 voltage stabilizing is imported, triode BG5 conducting, relay J 1 adhesive, accumulator works on for entire controller provides power supply after J1 normally opened contact closure.

(2) when civil power just often, after diode D2, resistance R 2, resistance R 3 dividing potential drops, provide a diode cathode that is higher than the voltage of Zener diode ZD3 voltage stabilizing value to photoelectrical coupler IC2 by the 24V direct current behind the commercial power rectification, make not conducting of photoelectrical coupler, triode BG5 also ends, relay J 1 discharges, cut off storage battery power supply, controller changes automatically by mains-supplied.

5, solve the stable measure of controller working procedure

Actual conditions are, by day, optical sensor VT might by temporarily shielding once and induction less than available light, thereby change its duty, shone by light and change duty, this is unallowed.No matter for guaranteeing that daytime, night can both the follow procedure operate as normal, the spy is provided with two delay circuits of timing integration block IC8, IC9 (being 4541).

Two circuit of IC8,1C9 are time-delay pin output in 5 minutes 8 high potential, its purpose is: when being operated in daytime, when causing optical sensor VT to accept light for a certain reason temporarily to be obstructed, triode BG14 just can end immediately, its collector potential then can become high potential by electronegative potential, NAND gate IC6-1 exports electronegative potential, though this moment, triode BG15 ended, IC8 does not have power supply, its 8 pin no-output, triode BG16 ends, but can not change the former stable state of the flip and flop generator of NAND gate IC6-3/4 composition.And two inputs of NAND gate IC6-2 are electronegative potential, and it exports high potential, and triode BG17 will conducting, timing integration block IC9 will establish the beginning timing by cable, in case 8 pin of IC9 become high potential, triode BG18 will conducting, and the flip and flop generator that NAND gate IC6-3/4 forms will overturn.But because timing integration block IC9 can delay time 5 minutes, so 8 pin of IC9 can not exported high potential in 5 minutes, therefore, triode BG18 can conducting in 5 minutes, the flip and flop generator that NAND gate IC6-3/4 forms can not overturn yet, and the state that controller is operated in daytime can not change.As continuous 5 minutes unglazed irradiation optical sensor VT, 8 pin of IC9 just can be exported high potential, and triode BG18 just understands conducting, the flip and flop generator that NAND gate IC6-3/4 forms just can overturn, it is output as high potential, shows just that at this moment the dusk deepened, and this enters the duty at night.Therefore time-delay in these 5 minutes has been arranged, can accomplish, needed only light and be no more than 5 minutes by retaining, controller still be considered as current be daytime and the daytime of automatically operating in state.In like manner, when being operated in night, can not change duty at its because penetrating the Ray Of Light that comes suddenly at night yet.
