A temperature detection system for cowshed environment based on wireless sensor network

Abstract

The invention provides a cowhouse environment temperature detection system based on a wireless sensor network which consists of a cowhouse environment parameter collection platform based on a wireless sensor network and a cowhouse environment multi-point temperature fusion model. The cowhouse environment parameter collection platform based on a wireless sensor network is used for cowhouse environment temperature detection, regulation and monitoring. The cowhouse environment multi-point temperature fusion model achieves cowhouse environment multi-point temperature fusion based on a similarity fusion weight, a distance fusion weight and a game theory combination weight calculated from a similarity matrix and a distance matrix of temperature Vague values of temperature sensors of multiple detection points in a cowhouse environment, so that the accuracy, reliability and robustness of cowhouse environment temperature fusion are improved. The system effectively solves the problems that a conventional cowhouse monitoring system does not detect the temperature of a cowhouse environment according to the characteristics such as nonlinearity and large lag of temperature changes of cow environment, large area of cowhouses and complicated temperature changes, so that cowhouse environment temperature detection is greatly influenced.

Description

technical field [0001] The invention relates to the technical field of agricultural livestock breeding automation equipment, in particular to a system for detecting the ambient temperature of a cowshed based on a wireless sensor network. Background technique [0002] The ambient temperature of the cattle house is the most important environmental factor, and it is also the most important factor leading to heat stress. As the ambient temperature rises, the body temperature of the beef cattle rises, and the dry matter intake (DMI) decreases. If the high temperature persists, the decline in DMI increases. . The ambient temperature has a hysteresis effect on the body temperature, and the body temperature also has a hysteresis effect on the feed intake. After a period of time when the indoor temperature rises, the tympanic membrane temperature begins to drop, and then the feed intake decreases. As the temperature rises, the temperature difference between the beef cattle's body te...
