The utility model has the advantages that compact conformation, easy to use, can write down on the crops insect automatically and take place dynamically.

The utility model is described in further detail below in conjunction with accompanying drawing.Fig. 1 is the cut-open view of front view of the present utility model, and Fig. 2 is a circuit diagram of the present utility model.

As shown in Figure 1 and Figure 2, press switch (14), circuit gets among the figure.To survey insect quantity in order writing down, must at first to press and ask zero switch (15), the numeral that makes demonstration is zero.

If insect sex attractant (12) does not attract insect to fall into the passage (4) of collecting insect, so by current-limiting resistance (16,70) and the infrared light that sends of infrarede emitting diode (17), aperture (7) directive space in passage (4), the output of infrared detecting device (3) pulse-free signal.If insect sex attractant (12) is attracted to insect and flies into high-voltage fence, after shooting dead, insect will fall into passage (4), and infrared light reflects on polypide, silicon photocell (18) is received, the silicon photocell two ends produce voltage, the first transistor (19) and transistor seconds (20) conducting, and electric current is through resistance (21,22,23,24,25) form the loop.Because transistor seconds (20) collector voltage is through resistance (26,27) dividing potential drop, the 3rd transistor (28) is ended, electric current can not be through resistance (29,30) form the loop, the collector that makes the 3rd transistor (28) is by coupling capacitance (31) output count pulse, add to the 12nd terminal pin (Y12) of BCD counter (54), at this moment, the 5th of BCD counter (54), 6,7,9 terminal pin (Y5, Y6, Y7 Y9) has signal output, pass through the 9th of code translator (55) respectively, 10,11,12,13,14,15 terminal pin (T9, T10, T11, T12, T13, T14, T15) and 7 resistance (32,33,34,35,36,37,38) remove driving LED charactron (39,40,41), simultaneously, the 2nd of BCD counter, 1,15 draw red pin (Y2, Y1, Y15) by 3 resistance (43,44,45) and 3 transistors (46,47,48) realize numeral selection output, guarantee that the LED charactron demonstrates arabic numeral according to count pulse quantity.

Before the 1000th count pulse arrives, because the differentiating circuit that electric capacity (49) and resistance (50) are formed is constantly carried positive and negative pulse to the trigger that two NOR gates (51,52) are formed.When the input positive pulse, second NOR gate (52) output low level, the kilobit of LED charactron (42) does not work.

When the 1000th pulse arrives, the 14th terminal pin (Y14) the output positive pulse of BCD counter, the first NOR gate output low level under the negative pulse of electric capacity (49) and resistance (50) output cooperates, makes second NOR gate output high level, by current-limiting resistance (53), the kilobit (42) of LED charactron is lighted, display digit " 1 ", and individual position (39), ten (40), hundred (41) show " 0 ", therefore, the numerical value of LED charactron demonstration is 1000.
