Embodiment Construction

[0028] (1) Detection node design

[0029] The detection unit is composed of temperature and humidity, illuminance and airflow sensors, filter circuit, signal conditioning circuit, communication nRF2401 module and MSP430 microcontroller. The temperature and humidity digital sensor SHT11 is used to collect the microclimate environment temperature and humidity of the chicken house and send it to the A / D conversion input circuit of the single-chip microcomputer. The wireless communication uses the nRF2401 module to build a wireless measurement and control network in the measured and controlled chicken house through self-organization to realize information interaction with the on-site monitoring terminal. , the system uses the nRF2401 module to connect to the RS232 interface of the computer to realize the communication between the on-site monitoring terminal and the chicken house microclimate environment monitoring and control node. Detect node structures such as figure 1 shown), ...

Abstract

The invention discloses a henhouse micro climatic environment intelligent control system based on a wireless sensor network. The henhouse micro climatic environment intelligent control system is characterized by comprising a henhouse micro climatic environment parameter acquisition and control platform, a henhouse micro climate farming environment cascade control system based on a DRNN PID neural network, and an expert system based on economic optimal reasoning and for setting ideal values of controlled henhouse micro climatic environment parameters. According to the invention, the henhouse micro climatic environment intelligent control system based on the wireless sensor network is designed through the characteristics of multiple parameter variables, nonlinearity, strong coupling and large inertia of conventional henhouse farming micro climatic environment.

Description

[0001] technical field [0002] The invention relates to the technical field of intelligent control equipment, in particular to an intelligent control system for the microclimate environment of a chicken coop based on a wireless sensor network. Background technique [0003] With the rapid development of large-scale chicken farming in recent years, the intensification and industrialization of the chicken industry have continued to increase, and the microclimate environment in the chicken house has an increasing impact on the health and production performance of chickens, creating a suitable environment for chickens The condition is the key link to prolong the peak laying period of laying hens and improve the economic benefits of raising chickens. As the disease resistance and health level of chickens are declining, it is even more required that the environmental control technology of large-scale chicken farming must keep up with the needs of modern chicken production, adjust ...
