A device for implementing the method, made in the form of a controller in a case (not shown) consists of a processor 15, to which are connected: a radio communication unit (not shown), an analog-to-digital converter (ADC) 16 for connecting sensors, control units for valves 17 and a pump 18 The valve control unit may be powered by a valve power supply 24. The controller also includes an IR receiver of the control panel 19, through which it can be controlled by an IR control panel (not shown). The controller also has a sound amplifier 20 connected to the notification speaker 25. To connect to a wired Internet network, an interface for connecting to the Internet 23 is provided. To provide service functions, the info / stop button 21 is provided. To ensure time synchronization, a real-time clock 22 is provided.

The controller is programmed to create operating pressure in the main pipeline, to control valves in accordance with the irrigation schedule and the algorithm for processing data from sensors for ambient temperature and soil moisture, and a pressure sensor in the main pipeline. The irrigation algorithm provides for the features of irrigation by zones: greenhouses or open ground, by type of plant: moisture-loving or not, by the cycle of water supply / shutdown.

A pressure pump may be present in the system, supplying water to the reservoir, depending on the type of water source. During storage of water in the tank, the water temperature is equalized with the ambient temperature, which, in summer, during irrigation in mid-latitudes, is usually higher than the temperature of water sources. It is also possible to heat water by absorbing solar energy from tanks. An additional improvement in water quality is achieved by using a filter through which water is pumped from the tank (s).

The technical result of increasing the stability of irrigation is achieved by the fact that the irrigation time may not coincide with the time of water supply to the storage tank, which is especially important with an unstable water supply or a large number of consumers and a stochastic decrease in water pressure in the supply system. EFFECT: increased uniformity of irrigation is achieved due to feedback from the sensor (s) of pressure in the water supply system and the ability to maintain optimal pressure for irrigation by turning on the discharge pump (s). EFFECT: water saving is achieved by the fact that there is no need for excessive watering of excessive watering due to the use of moisture and soil temperature sensors, as well as taking into account weather forecast information for the coming days. EFFECT: increased reliability is achieved by using a controller having the functionality of several devices, while reducing the number of contacts, conductors between devices, the probability of failure of each of which is non-zero.

Industrial application. The utility model can be successfully used for the production and operation of irrigation systems, including in conditions of unstable water supply.
