Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

As shown in Figure 1 and Figure 2, a kind of Intelligent spraying system of the present utility model, comprise Humidity Detection control circuit 1, not gate integrated trigger circuit 2, single chip machine controlling circuit 3 and drive circuit 4, the output signal of described Humidity Detection control circuit 1 transfers to not gate integrated trigger circuit 2, the output signal control of described not gate integrated trigger circuit 2 is sent to single chip machine controlling circuit 3 and drive circuit 4, and the output signal of described single chip machine controlling circuit 3 sends to RS485 communication interface circuit 31 and warning circuit 32.

Power circuit is comprised of power transformer T1, commutation diode VD1～VD4, filter condenser C1～C3 and circuit of three-terminal voltage-stabilizing integrated IC1, IC2 etc., the 220V alternating voltage is after power transformer T1 step-down, commutation diode VD1～VD4 rectification, circuit of three-terminal voltage-stabilizing integrated IC1 and IC2 voltage stabilizing, and supply voltage provides working power for the machine.

Described Humidity Detection control circuit 1 adopts the humidity sensor probe to gather moisture signal, (two probes are at a distance of 1～2mm) in the soil with moisture detector two probe insertion appropriate locations, humidity to soil detects, large in soil moisture, when reaching established standards, resistance value between moisture detector two probes diminishes, making the 1st pin and the 2nd pin of ungated integrated circuit IC3 is high level, the 3rd pin of ungated integrated circuit IC3 transfers low level to, transistor Q1 cut-off, relay J is failure to actuate, and pump motor M does not work.

When soil moisture reduces, resistance value between moisture detector two probes increases, making ungated integrated circuit IC3 the 1st pin and the 2nd pin is low level, the 3rd pin of ungated integrated circuit IC3 becomes high level, make transistor Q1 conducting, the relay J adhesive, the pump motor M work of switching on, equipment of sprinkler irrigation begins sprinkling irrigation.The 3rd pin output high level signal as ungated integrated circuit IC3, the 34th pin I/O end that this signal is input to single-chip microcomputer IC4 also is high level state, after single-chip microcomputer IC4 internal processes is processed judgement, send out two-way and send control signal, first via output is by the 2nd pin output low level of single-chip microcomputer IC4, through resistance R 6 current limlitings, make information ring device BY send alarm sound, the expression antecedent soil moisture; The the second tunnel output connects to form RS485 communication interface circuit 31 by the 1st, 2,3,4 ends of SN75176 communication interface chip IC5 and the 10th, 11,25 ends of single-chip microcomputer I C4, send data-signal by single-chip microcomputer IC4 to SN75176 communication interface chip IC5, change backward PC through SN75176 communication interface chip IC5 and send current data information, PC shows the current soil status information, instructs personnel to reach the spot and judges processing.

The output of described not gate integrated trigger circuit 2 also is connected with by the diode VD5, the resistor R5 that connect successively, the charging circuit that potentiometer RP3 consists of capacitor C4, and the high level of the 3rd pin of ungated integrated circuit IC3 output also charges to capacitor C4 through diode VD5, resistor R5, potentiometer RP3.After capacitor C4 charging finishes, the 3rd pin of ungated integrated circuit IC3 becomes high level, the 4th pin output low level of ungated integrated circuit IC3 makes diode VD6 conducting, transistor Q1 cut-off, relay J discharges, pump motor M quits work, if the resistance value between moisture detector two probes is still greater than setting value at this moment, and then again conducting of transistor Q1, repeat the above-mentioned course of work, until the resistance value between two probes is lower than setting value.

Above-described only is a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented, and every equalization of doing according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
