And 14V AC power supply to 5V and 12V DC power supply. One control card 34-3 controls two systems, and can be additionally set according to the scale of the irrigation system.

FIG. 5 is a component layout diagram of an example power supply card 34-2. Bridge diode A converts AC to DC,
The three-terminal regulator B sends 5 VDC and 12 VDC to the control card 34-3. The LED driver C visually displays the operation time point of the operational amplifier E in FIG. 6, and the sensor setting knob g in FIG.
The operating point of the solenoid valve 8 is set. With this function, the amount of hydration at the place where water is sprinkled can be controlled to a more desired level.

FIG. 6 is a diagram showing an example of a component layout of a control card. The control card 34-3 is the center of the automatic watering apparatus. The CR timer D determines the operation time of each solenoid valve 8. When the operating power is supplied to the double relay G, the power ON signal H is supplied to the CR timer D. By turning the timer set knob j in FIG. 3, the time can be adjusted from 30 seconds to 6 minutes. First relay is off
Then, the power is turned on to the second double relay G, the same operation is repeated, and all the operations are stopped when the last relay is turned off. The operational amplifier E converts a voltage corresponding to the water content of the place where the sensor 8 of FIG. 2 is installed and a voltage obtained by the variable resistor of the sensor set knob g of FIG. 3 into a constant value set by the operational amplifier E. Is reached, the output is reversed and the solenoid valve 8 is opened and closed. When the sensor 8 comes off and its resistance becomes infinite, the operational amplifier E controls the solenoid valve 8 so as not to be left open. The AND circuit F receives O from both the CR timer D and the operational amplifier E.
Activate the dual relay G only when the N signal comes. Using this AND circuit, the sensor / timer control switch k is used to determine whether to switch the sensor / timer control only for the timer or to use the sensor / timer together. The automatic / manual switching is performed by turning off an ON signal from an operational amplifier E of an AND circuit F by turning off a water supply automatic / manual changeover switch e shown in FIG. 3, and then manually operating a manual water supply switch f instead. Do.

FIGS. 7 and 8 are an installation view and a cross-sectional view of an example of a sensor 9 for detecting the water content of a watering place. In principle, simply use two metal rods as electrodes, detect that the electrical resistance between these two electrodes changes with soil quality and moisture content, and guide the value to the control card with electric wires. It is. The metal rod 9c as a sensor is made of, for example, a copper rod having a good dielectric constant and resistant to rust, or a stainless rod with an increased resistance value. The distance between the two poles should be approximately 50 as an example so that it can be measured from the end of the large planter box.
cm sensor width 2 sensor type 9a and 1 sensor type 9b
There are seeds. Two types are suitable for wide planters, and one type is suitable for small planter boxes. The sensor wiring 9d may be a single-line shielded commercially available microphone cable that is resistant to moisture and direct sunlight. FIG. 8 shows a cross-sectional view. 9a is a two-piece type,
9b is a single type. The metal rod 9c is insulated by an electrically insulating shield 9e having a length of about 15 cm. Insert to the desired depth and detect the water content at that position. The single-type sensor 9b has a metal tube 9 placed on an electrically insulating shield 9e.
f is overlapped, and the other sensor wiring is connected to form two poles. If electrical insulation is lost in the middle of the sensor, the meaning of the sensor will not be fulfilled, so the sensor is covered with an insulating cover 9g. The electric resistance of the soil does not change much because the distance between the sensors is a surface contact, and changes depending on the quality and moisture of the soil. Synthetic soil for planters has low resistance and soil such as general fields has high resistance. As a result of the measurement, the resistance value of the soil containing a large amount of water having high conductivity is about 2 KΩ, while the resistance value of the soil which is low in conductivity and is considered to be incapable of plant habitation is about 40-50 KΩ. Met. Accordingly, the value of the variable resistor of the sensor set knob g in FIG.
It is set to KΩ. This system enabled watering to be adapted to any conditions.
