Intelligent controller for straw bioreactor and control method thereof

Abstract

The invention discloses an intelligent controller, and particularly relates to an intelligent controller for an external straw bioreactor for protective land production and conversion from straws to carbon dioxide gas fertilizer. The intelligent controller for the straw bioreactor structurally comprises an air supply control system, a switch, a liquid discharge control system and a water level sensor, wherein the air supply control system sends working instructions to an air supply motor according to various different switch instruction; the switch sends working instructions to the air supply control system under different working conditions; the liquid discharge control system sends working instructions to a liquid discharge pump according to signals sent by the water level sensor; and the water level sensor transmits working signals to the liquid discharge control system after the water level reaches a set value. The intelligent controller has the characteristics of convenient setting, simple operation, convenient use, intelligence, high efficiency, small volume, flexible and convenient operation and safe use, and can greatly simplify the management program, simplify complex problems, enable a user to quickly master the management technical point of the straw bioreactor and reduce the production cost of the protective land of the user.

Description

technical field [0001] The invention relates to a controller, in particular to an external straw bioreactor controller and a control method for converting straw into carbon dioxide gas fertilizer. Background technique [0002] One of the keys to production in rural protected areas in winter is to reduce the amount of pesticides and fertilizers while increasing crop yields, and to reduce production costs while ensuring food safety. The traditional production process relies on pesticides to suppress pests and diseases, chemical fertilizers to increase crop yields, and artificial chemical methods to prepare carbon dioxide gas fertilizers to meet the needs of crops for carbon dioxide. [0003] Straw is a kind of biomass resource. Due to the lack of mature conversion technology, most of the straw is abandoned in the field, piled up randomly or set on fire, which not only causes a great waste of resources, but also seriously pollutes the ecological environment. Straw bioreactor t...

AI Technical Summary

Problems solved by technology

[0004] Although the straw bioreactor technology can solve the environmental pollution caused by burning straw and the shortage of carbon dioxide in greenhouse crops, it has not been able to be popularized on a large scale due to the constraints of complex management and control.
