AUTOMATIC MODULAR VERTICAL GREENHOUSES FOR HYDROPONICS Russian patent published in 2023 - IPC A01G31/06 

FIELD: agricultural machinery.

SUBSTANCE: invention relates to modular devices for vertical greenhouses for growing fast-growing green plants. The device includes a body made of a metal frame, an automatic control unit installed in the frame and interconnected by pipes and a hose from the bottom to the top at least two plant modules with trays with cells installed in them, a tank for a nutrient solution, a pump for circulating a nutrient solution, LED phytolamps, a carbon dioxide supply module and valves for water supply, nutrient solution circulation and waste solution drain. The automatic control unit is fixed on the body and is made in the form of a control cabinet based on a programmable logic controller (PLC) with an operator panel with a liquid crystal touch-controlled screen, with the functionality to control the modes of growing, lighting and ventilation of plant modules. Modules for measuring nutrient solution parameters and measuring air parameters are additionally introduced into the automatic control unit for growing a green plant culture, while the module for measuring nutrient solution parameters contains a pH meter for measuring the acidity level of the solution, which consists of a sensing element and a 0-5 V converter board, a TDS meter for measuring the total salt content in a solution, which consists of a sensor and a signal converter to a voltage of 0-2.5 V, and a water temperature sensor, and the air parameter measurement module contains a CO₂ concentration sensor based on the MH- Z19C and an air temperature sensor. Both modules are connected to the interface converter into RS485 protocol ModBusRTU, which allows connecting the modules directly to the PLC. The device contains at least five peristaltic pumps, each of which is connected at one end to its mother liquor tank, and at the other end to the nutrient solution tank.

EFFECT: expanded functionality of vertical greenhouses on hydroponics, quick and easy expansion of space for seedlings due to satellites.
