Intelligent detection system for ammonia gas in cowshed environment based on wireless sensor network

Abstract

The invention discloses an intelligent detection system for ammonia gas in a cowshed environment based on a wireless sensor network. The intelligent detection system is characterized by being composed of an intelligent cowshed environment parameter detection platform based on the wireless sensor network and an intelligent cowshed environment ammonia gas detection model, wherein the intelligent cowshed environment parameter detection platform based on the wireless sensor network is capable of detecting, regulating and monitoring cowshed environment factor parameters; the intelligent cowshed environment ammonia gas detection model comprises a clustering classifier based on a genetic algorithm (GA) and a fuzzy C mean (FCM), a plurality of fuzzy wavelet neural network ammonia gas models, and an ammonia gas concentration value fusion model based on Euclidean distance, so that intelligent software measurement of the cowshed environment ammonia gas is realized. According to the system disclosed by the invention, the problems that the ammonia gas concentration in the cowshed is influenced by multiple environmental factors such as temperature, humidity, ventilation, illumination conditions in the cowshed and an accurate measurement model is hard to establish by the traditional mathematical method are effectively solved.

Description

technical field

[0001] The invention relates to the technical field of agricultural livestock breeding automation equipment, in particular to a wireless sensor network-based intelligent detection system for ammonia in the cowshed environment. Background technique

[0002] Ammonia in the cowshed environment is a colorless gas with a pungent odor and is easily liquefied into a colorless liquid that can burn the skin, eyes, and mucous membranes of the respiratory organs. The source of ammonia in the barn environment is mainly nitrogen-containing organic matter, which is usually produced by the decomposition of manure, feed and bedding. In addition, excessive feeding of non-protein ammonia, cattle belching, and the amount of ammonia excreted will also increase. The ammonia in the air of the cowshed is mainly from the decomposition of organic matter such as gastrointestinal digestion, excrement, feed residue and bedding, and is produced by bacteria decomposing cow body waste.
