Compared with prior art, the beneficial effects of the utility model are: go mouldy detection warning circuit simple in construction, components and parts of this utility model silo grain are few, it is capable of the monitor in real time to the temperature and humidity within grain heap, will start to report to the police as long as two kinds of indexs have one to go beyond the scope, staff is reminded to investigate problem in time, avoid large-scale loss, therefore have and control accurate, easy to use and that volume is little advantage.
Accompanying drawing explanation
Fig. 1 be silo grain go mouldy detection warning circuit circuit diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments. Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1, a kind of silo grain goes mouldy detection warning circuit, including audion V1, power supply E, switch S1 and loudspeaker B, one end of described switch S1 connects the positive pole of power supply E, the other end of switch S1 connects resistance R2, resistance R3, resistance R10, resistance R11, the emitter stage of the fixing end of of potentiometer RP1 and audion V5, the colelctor electrode of the other end connecting triode V1 of resistance R2 and the emitter stage of triode V3, the other end of resistance R10 connects the base stage of resistance R1 and audion V1, the emitter stage of triode V1 connects the emitter stage of resistance R4 and audion V2, the base stage of audion V3 connects the other end of resistance R3 and the colelctor electrode of audion V2, the colelctor electrode of audion V3 connects the anode of resistance R6 and diode D1, the negative electrode of diode D1 connects the base stage of resistance R7 and audion V4, the other end of resistance R1 connects the negative pole of power supply E, the other end of resistance R4, resistance R5, the other end of resistance R6, resistance R9, the emitter stage of loudspeaker B and audion V4, the other end of resistance R5 connects another fixing end of potentiometer RP1, the base stage of audion V2 and the sliding end of potentiometer RP1, the other end of resistance R7 connects the other end of resistance R11, the colelctor electrode of audion V4 connects resistance R8, the other end of resistance R8 connects the base stage of electric capacity C1 and audion V5, the other end of electric capacity C1 connects the other end of resistance R9, the colelctor electrode of audion V5 connects the other end of loudspeaker B.
Resistance R10 is critesistor. Resistance R11 is humistor.
Operation principle of the present utility model is: critesistor R10 and humistor R11 in circuit are arranged in grain to inside, and audion V4 and V5 constitutes electrical switch and audio oscillator, plays the effect of the too high alarm of humidity. V5 and loudspeaker B form alarm circuit, and V4 is that electrical switch is held concurrently current amplifier, and when base stage has enough electric currents to flow through, with regard to saturation conduction, such resistance R8 just has electric current to flow through, audio oscillator starting of oscillation, otherwise, agitator not starting of oscillation.
When humistor R11 detects that grain heap is internal, humistor R11 two ends resistance drops to below 1OOk ��, thus the base current producing more than 10uA makes audion V4 turn on, loudspeaker B sends chimes of doom; When grain heap is internally dry, humistor R11 two ends resistance value is relatively big, and audion V4 is not turned on, thus does not report to the police.
Overtemperature alarm is made up of bridge for measuring temperature R10, R1, RP1, R5, audion V1, V2 and V3, diode D1. Under normal circumstances, bridge for measuring temperature internal balance, at this moment audion V3 cut-off, thus audion V4 is also switched off, and does not report to the police; When grain goes mouldy, the temperature within grain heap raises, and bridge balance destroys, then audion V3 conducting, making audion V4 turn on by diode VD, loudspeaker B sends chimes of doom equally, adopts temperature and humidity two kinds to trigger type of alarm and further increases the sensitivity of detection.
