In figure: 1-resistance detecting circuit, 2-water content detection circuit, 3-power change-over switch, 4-power circuit.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1: the utility model comprises resistance detecting circuit 1, water content detection circuit 2, power change-over switch 3 and power circuit 4, the circuit output end of power circuit 4 is connected with the center-side of power change-over switch 3, one end of power change-over switch 3 is connected with the power input of resistance detecting circuit 1, and the other end of power change-over switch 3 is connected with the power input of water content detection circuit 2.
Particularly, resistance detecting circuit 1 is made up of the first resistance R1 to the 5th resistance R5, the first reometer A1, the first electric capacity C1, the second electric capacity C2, the first diode VD1, the second diode VD2, the first potentiometer RP1 to the 3rd potentiometer RP3, the first test side A, the second test side B and triode VT; Water content detection circuit 2 by the 6th resistance R6 to the tenth resistance R10, the 3rd electric capacity C3 to the 5th electric capacity C5, the first resistance selector switch S1 to the 3rd resistance selector switch S3, main switch K, LED, the 3rd test side C, the 4th test side D with time basis set become chip IC to form; Power circuit 4 is made up of to the 9th electric capacity C9, the 11 resistance R11, the 4th potentiometer RP4, the 3rd diode VD3, the 4th diode VD4, voltage stabilizing chip IC 2, second reometer A2, rectifier DR and transformer T the 7th electric capacity C7.
Principle of work of the present utility model is as follows:
In resistance detecting circuit 1, when the first test side A, the second test side B do not insert tested fermentation crops, in the first reometer A1, no current flows through.When the first test side A, the second test side B insert tested fermentation crops, the internal resistance of crops is attempted by the input end of the first reometer A1, the base current of triode VT is increased, after amplifying, collector current also increases, first reometer A1 two ends produce potential difference (PD), indicator swings, and has electric current to flow through.Because during test, the resistance of the first potentiometer RP1 and the first resistance R1 is constant, so the base current size of triode VT and fermentation crops internal resistance size are inversely.As long as the indicated value of read current table, the resistance of fermentation crops just can be known.Utilize the method for above-mentioned measurement crops internal resistance to measure attenuation degree.Can under certain storing spot and ambient temperature conditions, every several hours or one day, measure the internal resistance of certain crops fermentation continuously, from fresh to completely putrid and deteriorated, draw the internal drag curve of this food time to time change. sum up the rule of crops corruption change.Scientifically utilize and store fermentation, reducing the loss caused because of rotten.
Water content detection circuit 2 be by time basis set become chip IC 1, the 6th resistance R6 etc. to form oscillator, moisture is how many relevant with the size of the resistance at the 3rd test side C, the 4th D two ends, test side.Moisture height is then worth little, and oscillation frequency is high; Otherwise oscillation frequency is low.After switching on power, loudspeaker sends electric current sound, and LED is luminous.Utilize the resistance of the 8th resistance R8 to the tenth resistance R10 to participate in vibration respectively, repeatedly compare the oscillation frequency of RI, thus judge the content of moisture.
