A kind of environment control system and control method of mushroom house of Agaricus bisporus

Abstract

The present invention provides an environment control system and control method for Agaricus bisporus mushroom room, comprising the following steps: (1) The temperature control program of the central controller calls the preset culture material soil temperature st s , the actual culture material soil temperature value st c , the response speed coefficient r, the maximum and minimum values ​​of the suitable growth temperature of Agaricus bisporus, the temperature control program includes a reasoning module and a fuzzy control module, and the reasoning module calculates the preset ambient temperature value et s ; (2) input the preset ambient temperature value et obtained in step (1) into the temperature fuzzy control module s , The actual environmental culture material soil temperature value st detected by the environmental temperature sensor c ; The temperature control signal used to control the temperature adjustment of the air conditioner is calculated by the temperature fuzzy control module. The invention comprehensively regulates the temperature of the culture material soil and the environment temperature by introducing the response speed of the temperature of the culture material soil and the environment temperature, thereby improving the control efficiency.

Description

technical field [0001] The invention relates to a Agaricus bisporus cultivation technique, in particular to an environment control system and a control method for a Agaricus bisporus house. Background technique [0002] In the prior art, greenhouses (including greenhouses, mushroom houses, and bacteria houses) used for the cultivation of edible fungi, vegetables, and flowers need to control the greenhouse environment according to the growth requirements of the cultivated crops. The environmental factors (factors) involved There are temperature, humidity, carbon dioxide concentration, etc., and temperature and humidity can be divided into air temperature and humidity, cultivation soil temperature and humidity. For example, the Chinese invention patent with the notification number CN104238602B discloses "Greenhouse Environment Intelligent Control and Management System Based on Information Collection", which uses multiple types of sensors for separately collecting various envir...

Problems solved by technology

[0003] The existing greenhouse environment control system, such as the above-mentioned "greenhouse environment intelligent control management system based on information collection", its soil temperature, soil humidity, air temperature, and air humidity are regulated separately. If any one of the environmental information exceeds the threshold, the system will It will respond and adjust accordingly. Due to the large number of thresholds that need to be set, it not only requires a lot of work in the early stage, but also leads to frequent system adjustments, and there is a problem of low efficiency of environmental regulation.

[0004] For some edible fungi, such as Agaricus bisporus, the growth process can be divided into two stages: mycelium development and fruiting body growth. Different stages have different requirements for environmental factors. Environmental factors directly affect the growth rate of mycelia and fruiting bodies. In order to meet the demand, the environmental control system of Agaricus bisporus factory production in the prior art is a complex system with nonlinear, multi-input and multi-output, and the continuous change of outdoor environmental factors constantly affects the change law of the mushroom house environment , Uncertainty is an unavoidable problem in real control applications, so the control algorithm must modify its own parameters in real time according to the situation of the mushroom house

However, the above-mentioned existing technologies are now used for regulation, and the parameter setting and adjustment of suitable environmental factors are extremely complicated, and it is difficult to meet actual production needs.
