Embodiment Construction

[0021] Such as figure 1 As shown, the intelligent control system of the miniature plant factory is composed of environmental factor acquisition module, data storage module, human-computer interaction module, processor module and execution control module. The STM32 controller regularly sends data collection commands to the corresponding sensors. After receiving the commands, the sensors collect the internal environmental data of the micro plant factory, and then return the collected data to the controller. The control system fuses the collected data Send it to the SD card for storage, and then control the on / off of the corresponding relay according to the judgment of the environmental factor threshold value that has been set for crop growth, and then control the on / off of the relevant heating tubes, compressors and other actuators. The control system continuously repeats the previous process and continuously detects environmental factors, forming a closed-loop automatic control...

Abstract

By utilizing the embedded technology, a miniature plant factory intelligent control system based on an STM32 is invented. The miniature plant factory intelligent control system regards the STM32 microprocessor as a hardware core, is combined with a mu C / OS-II operating system, realizes the real-time display and precise control of several environmental factors such as temperature, humidity and illumination inside a miniature plant factory, puts forward a temperature and humidity fuzzy decoupling method and adopts a fuzzy control algorithm to perform temperature and humidity control, effectively solves the problem of large delay and strong coupling in temperature and humidity control, and has high practicability.

Description

technical field [0001] The invention relates to a detection device, in particular to an intelligent control system for a miniature plant factory. Background technique [0002] The micro plant factory is a new thing that has emerged in the facility agriculture industry in recent years. It further concentrates the technology of large plant factories, controls the crop growth environment through an intelligent automatic control system in a limited and airtight environment, and provides suitable temperature and humidity, light intensity, and CO2 for crops. Concentration and reasonable ratio of nutrient solution to achieve annual continuous planting of crops. At present, due to the limitations of cost and technology, the promotion and application of micro plant factories are still in the research and exploration stage. [0003] Miniature plant factories have great application potential. In countries such as Japan, the United States, and the Netherlands, where plant factory techn...
