A household plant growth chamber and its multi-objective optimal control method

Abstract

The invention discloses a domestic plant growth box and a multi-objective optimization control method thereof. The growth box comprises a control chamber and a growth chamber, the growth chamber is provided with an LED (light-emitting diode) light source, an air inlet fan, an air outlet fan, a heating wire, a CO2 connecting hose, an indoor temperature and humidity sensor and a CO2 sensor, tin foilpaper is stuck on the inner wall of the growth chamber, the LED light source is placed at the top of the growth chamber, the air inlet fan and the air outlet fan are positioned on the inner wall of the growth chamber, the heating wire and the CO2 connecting hose are positioned in a groove of a partition plate, the control chamber is provided with an air switch, a switch power supply, a status indicator lamp, a controller, a timer switch, a CO2 steel bottle, a pressure adjusting valve, a CO2 solenoid valve and an audible and visual alarm, the control chamber and the growth chamber is separatedby the partition plate, corresponding adjusting schemes are selected by the controller according to data income by the sensors, so that the growth box is heated, cooled and dehumidified, balance of CO2 in the box is maintained, environmental requirements of plant growth are met, and the growth efficiency of the growth box and the quality of crops are improved.

Description

technical field [0001] The invention belongs to the technical field of plant growth, in particular to a household plant growth box and a multi-objective optimization control method thereof. [0002] technical background [0003] With the rapid development of the global economy and the continuous improvement of people's living standards, balcony agriculture is rapidly emerging. The plant growth box is favored by the public because of its simple equipment and convenient control. Plant growth depends on its external environment, such as light, temperature, humidity, CO 2 Concentration and other environmental factors, the fluctuation of the environment in the box directly affects the growth and development of plants, and affects the yield and quality of plants. It is of great significance to adjust the environmental factors in the growth box to meet the growth of crops. [0004] In the prior art, such as the Chinese patent (CN201310468423.1), the temperature and humidity, light...

AI Technical Summary

Problems solved by technology

However, this kind of plant growth box is expensive and occupies a large area, which is suitable for factory production and not suitable for ordinary households.

In addition, the existing plant growth chamber control methods ignore the light, temperature, humidity, CO 2 There are strong interactions, nonlinearity, multiple constraints, and conflicting relationships between concentrations, which will inevitably lead to untimely adjustment and energy waste, which puts forward higher requirements for the control in the growth chamber
