Description of drawings
Fig. 1 is the utility model circuit theory diagrams;
Fig. 2 is the utility model AC voltage-stabilizing circuit schematic diagram.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, moisture detection probe, temperature detection probe, illumination detection probe, audio frequency oscillator and power circuit are formed, and moisture detection probe is made up of the metal that two ends isolate; The temperature detection probe is made up of thermistor; The illumination detection probe is made up of photodiode; Audio frequency oscillator is made up of transistor; Power circuit is divided into AC voltage-stabilizing circuit and the power-supply battery power supply circuits that can change automatically mutually.
Wherein: the metal that moisture detection probe is isolated by two ends is formed in the monitored soil of insertion, the size of probe two ends soil moisture content has determined to flow through the first triode BG1 base current size, when soil moisture moderate, the first triode BG1 base stage has enough electric currents to pass through, and the current value that the ammeter MA that connects in the colelctor electrode flows through is the humidity size.When antecedent soil moisture was above to setting value, because the first triode BG1 base current reduces, ammeter MA deflection angle diminished, and this moment, the emitter stage current potential raise, and the 3rd diode D3 is luminous in the second triode BG2 conducting, and prompting the manager water.The electronic switch signal of being made up of the 1st～2 diode D1～D2 is delivered to audio frequency oscillator simultaneously, audio frequency oscillator is started working, the prompting of sounding.
The temperature detection probe adopts thermistor R13, place detected environment (air, soil, water), when the temperature detection detected numerical value of popping one's head in is lower than when setting value, thermistor R12 resistance raises, cause that the 6th triode BG6 ends, the 7th triode BG7 conducting, the output light is reported to the police and the sound enabling signal simultaneously.
The illumination detection probe adopts photodiode D4, and when illumination did not reach setting value, it is big that photodiode D4 resistance becomes, the 3rd triode BG3 conducting, and the 4th triode BG4 base earth ends, and the ammeter MA of display light photograph returns zero.At this moment the tenth resistance R 10 makes the 5th triode BG5 conducting, and the 5th diode D5 is luminous, and starts the audio-frequency oscillator sounding by the 6th diode D6.
Audio frequency oscillator is made up of the seven～eight triode BG7～BG8, and trigger end links to each other with the test circuit of described humidity, temperature, three variations of illumination.When one tunnel ginseng utmost point wherein changes, just start oscillator after exceeding predetermined value, or two, the three road exceed standard simultaneously, can start oscillator equally, specifically whether which road parameter luminous judgement is exceeds standard from three light emitting diodes.
Power circuit is divided into AC voltage-stabilizing circuit (referring to Fig. 2) or power-supply battery power supply circuits, and two circuit can be changed mutually.Work at ordinary times based on AC voltage-stabilizing power supply (being connected across K switch 1 two ends), can reduce operating cost; In case convert powered battery to after the outage, to guarantee continuous monitoring, prevent that night, the manager slept after, booth is by animal or artificial destruction, causes temperature decrease and the loss that brings.
