Method for distributing temperature and humidity sensors in Maitake mushroom house

Abstract

The invention relates to a method for distributing temperature and humidity sensors in a Maitake mushroom house. The method comprises the steps that firstly, establishing a corresponding mathematical and physical model of a temperature field in the Maitake mushroom house and a corresponding mathematical and physical model of a humidity field in the Maitake mushroom house according to the CFD method; secondly, in consideration of factors such as solar radiation and conditions of the mushroom house, carrying out numerical simulation on a given geometric form (domain) of the mushroom house; thirdly, mastering the distribution of the temperature field and the humidity field in the mushroom house, instructing initial installation of the temperature and humidity sensors, and designing a temperature and humidity monitoring system of the Maitake mushroom house; finally, according to contrastive analysis of temperature and humidity testing data collected by the temperature and humidity monitoring system of the Maitake mushroom house and a numerical simulation result, determining simplified measuring point positions for temperature and humidity detection in the Maitake mushroom, and then determining an optimized distribution mode of the temperature and humidity sensors. By means of the method, data reflecting temperature and humidity change in the mushroom can be accurately detected by the monitoring system through as few temperature and humidity sensors as possible, so that needed labor and needed detection cost are reduced, and the diagnosis efficiency is improved.

Description

technical field [0001] The invention relates to a method for distributing temperature and humidity sensors in a Grifola frondosa mushroom house. Background technique [0002] The temperature and humidity of the growth environment are important factors affecting the yield and quality of Grifola frondosa, and Grifola frondosa in different growth stages have different requirements for temperature and humidity. For example, the most suitable external temperature environment for the growth of Grifola frondosa mycelia is 24°C-27°C, and the optimum external environment temperature for the occurrence of fruiting bodies is 18-21°C. It can be judged whether the growth of Grifola frondosa in the mushroom house is in a normal state by detecting the temperature and humidity inside the mushroom house. When the environmental factors in the mushroom house, especially the temperature and humidity are not coordinated, it is easy to cause deformed mushrooms of Grifola frondosa. For example: ...

AI Technical Summary

Problems solved by technology

Automatically controlled measuring points generally only select the temperature and humidity of a point in the space as the control basis. The selection and layout of measuring points are rarely explored and optimized, resulting in one-sidedness and inaccuracy of data collection.

Or because the mushroom house is usually built in the form of a small shed with a large shed, the space is relatively large, and the overall cultivation area is also relatively large. Under the condition of mechanical ventilation, the temperature and humidity distribution in the mushroom house is not uniform. There is no experimental reference when measuring the temperature and humidity values ​​at multiple points in the mushroom house, resulting in excessive labor consumption in the manual measurement of temperature and humidity in the mushroom house, and the measurement efficiency is not high
