Below in conjunction with accompanying drawing, the utility model is described in further detail.
Accompanying drawing explanation
Fig. 1 is composition frame chart of the present utility model;
Fig. 2 is circuit theory diagrams of the present utility model;
Fig. 3 is main program flow chart of the present utility model.
Embodiment
See Fig. 1, whole system is made up of single-chip microcomputer, solenoid valve control circuit, magnetic valve, water pump control circuit, water pump, level sensor, soil humidity sensor and water pot.Solenoid valve control circuit and water pump control circuit comprise photoelectric isolated chip and relay, solenoid valve control circuit is all connected with single-chip microcomputer with soil humidity sensor with the photoelectric isolated chip in water pump control circuit, level sensor, water pump is connected between relay in water pump control circuit and water pot, and magnetic valve is connected between relay in solenoid valve control circuit and water pot.
Single-chip microcomputer adopts AT89C2051 chip, and magnetic valve adopts 2WB stainless steel solenoid valve for water, and photoelectric isolated chip adopts PC817.Level sensor adopts liquid-level floater switch, and liquid-level floater switch is primarily of magnetic reed switch and float composition, and magnetic material in float, when float moves up and down with tested liquid level, touch magnetic reed switch and detect liquid level position, the output of signal is switching value.Soil humidity sensor adopts tensiometer detection module, soil moisture is regulated to control threshold values by potentiometer above, the humidity of soil can be controlled by wide region, when humidity is lower than setting value, DO exports high level, during higher than setting value, DO output low level, export DO to be directly connected with single-chip microcomputer, by microprocessor detect low and high level, detect soil moisture thus, during probe can directly be placed into the soil, being suitable for agricultural greenhouse booth, flowers, nursery, lawn etc. needs the occasion detecting soil moisture environment to use.
Circuit theory diagrams of the present utility model as shown in Figure 2,20 pins of control single chip computer connect power supply, 10 pin ground connection, 4, the external crystal oscillating circuit of 5 pin, P1.2 connects solenoid valve control circuit, controls the open and close of water intaking valve, P1.3 water pump control circuit, control the start and stop of water pump, P1.4, P1.5, P1.6 are respectively as the signal input part of upper, middle and lower level sensor, and P1.7 connects the signal input part of soil humidity sensor.
Fig. 3 is main program flow chart of the present utility model, and single-chip microcomputer, as master controller, according to level sensor and soil humidity sensor signal, controls water intaking valve and water pump, and then controls injection and the utilization of rainwater.When water pot water level is higher than upper liquid level, close water intaking valve, stop injecting rainwater; When water pot water level is lower than middle liquid level, open water intaking valve, inject rainwater; When water pot water level is lower than lower liquid level, ensure that water pump can not start; Soil humidity sensor export high level, and water pot water level higher than lower liquid level time, starting mode of pump.
