Description

The utility model relates to the field of agriculture and can be used for irrigation of crops and indoor plants.

Known devices in this field, for example, an irrigation device used for mechanization of irrigation, irrigation of crops by automatic discrete water supply to the foci of humidification. The irrigation device includes a tray mounted on board a siphon tray with a charging mechanism consisting of a tipping bucket installed with the possibility of draining a portion of liquid into a receiving tank in communication with the drain siphon of the siphon below the end of its suction elbow, the device is equipped with a liquid level sensor tube in the tray, and the bucket is located under the replaceable end of the sensor tube, is equipped with a counterweight and is pivotally mounted on the horizontal axis. (Patent RU No. 20169625 C1, 09.15.1994, AS USSR No. 941466)

The disadvantage of these devices is the siphon design that is not reliable enough to operate, which leads to interruptions in the water supply to plants, as well as a low level of automation of the device and, as a result, the difficulty in operating the irrigation system as a whole.

A device for watering plants containing a receiving container for water, a feeding tube, a siphon with a trigger mechanism, a suction elbow and a sensor tube connected to the atmosphere, a hydraulic channel communicating with the siphon, and a distribution

a plant watering pipeline, according to the invention, the feeding tube is equipped with a metering valve with a shut-off device, and the siphon is made in the form of a tee with two inlet nozzles and one or two outlet nozzles, while one inlet nozzle is connected via a hose to the siphon trigger mechanism, the other to the tube to the sensor, and the outlet pipe to the hydraulic channel, the latter being connected via a splitter to a distribution pipe for watering plants, the ends of which are equipped with droppers, This siphon trigger mechanism contains a hydraulic pump, which is installed at the bottom of the receiving tank and is equipped with an electronic starting device (EPU) with a programmer and a photoelectric sensor, while the EPU is configured to automatically control the process of watering plants according to a predetermined program coordinated with day-night transition cycles . Watering always begins with the onset of the evening, while the EPU does not count the time, but the cycles of day-night transition. The technical result achieved by the implementation of this invention is the automation of the process of spot irrigation of plants with a periodic mode of operation of the system, consistent with the current time of day and associated with the natural daily life cycle of plants. (RU 2331189 C2, 03/10/2008.)

The disadvantage of the prototype is the fact that when using this device, soil moisture is not taken into account, but a specific start time and duration of irrigation are programmed, i.e. even if the plant does not need watering under any conditions, it will turn on, which can lead to the death of the plant.

Based on the foregoing, it follows that a technical problem that could not be solved in the presented analogues is the high consumption of water for watering plants, resulting in increased energy consumption. The technical result of the proposed device is to obtain high-quality products while reducing energy consumption.

To solve this problem, the device is equipped with a humidity sensor connected to the Arduino Uno microcontroller, while the microcontroller is connected via a discontinuous relay to the water supply pump.

The microcontroller can work both in conjunction with a computer, and autonomously, receive power through a USB connection from an external power source. External power can be supplied via an AC / DC voltage converter (power supply) or a battery. The device supports Linux, MacOS and Windows operating systems. For programming and communication with a computer, a USB cable is used, and for working in stand-alone mode, a power supply is required. With the help of additional expansion cards, it becomes possible to organize other methods of interaction, for example, Wi-Fi, a radio channel, and the Internet. This Arduino Uno microcontroller has the ability to interact with peripheral devices through applications.

The device is illustrated by drawings: In FIG. 1 shows a general diagram of a device. In FIG. 2 is a diagram of the connection of the elements of the device.

The device for automatic irrigation includes an Arduino Uno 1 microcontroller, to which a display 2 is connected, which reflects the readings from the humidity sensor 3. The microcontroller 1 is connected via a discontinuous relay to the pump 4 for supplying water from the tank 5 with the shut-off device 6. The pump 4 is immersed in the tank 5 for water through a distribution pipe 7 for watering plants, the ends of which are equipped with droppers.

A device for automatic watering of plants works as follows. Water from the pipeline enters the water tank 5 with a shut-off device 6, which turns off the water when it is sufficiently filled. A pump 4 for immersing water through a distribution pipe 7 for watering plants, the ends of which are equipped with droppers, is immersed in a container 5. The number of droppers mounted and the size of the interval between them are determined by the age and height of garden crops, structural features of the soil and planting density. Pump 4 is connected to the Arduino Uno 1 microcontroller via an interrupt relay (switch). Moisture sensor 3, installed in the soil and connected to the Arduino Uno platform. A digital display 2 is connected to the microcontroller 1, which reflects the readings read from the humidity sensor 3. The device is powered by a stabilized DC voltage source of 5 V. When turned on, the device displays the current state of the soil and the approximate soil resistance. The Arduino Uno 1 microcontroller, after a set time, requests soil moisture readings from the sensor. Moisture sensor 3, seeing a request, sends a response to the microcontroller, which, when the soil moisture level is reduced to a certain value, turns on pump 4 to supply water to the plant. When water is added to the soil, the device indicates a change in the conductivity of the soil and signals its sufficient moisture. As soon as the amount of moisture in the soil reaches the set parameter, the sensor 3 sends a signal to the microcontroller 1, which turns off the pump 4 for water supply.

The norms of water consumption, depending on the period of the year when growing vegetables using the proposed device are shown in table 1.

Table 2 shows the main technical characteristics of the system depending on its configuration according to the proposed device.

Compared with the prototype, the proposed device will evenly moisten the soil, taking into account the composition of the soil, the type and age of the plant, which must be watered and with reduced energy consumption to obtain high-quality products.
