Pig house environment temperature detection system based on CAN (controller area network) bus

Abstract

The invention discloses a pig house environment temperature detection system based on a CAN (controller area network) bus. The pig house environment temperature detection system is characterized by comprising a CAN bus based pig house environment parameter collection platform and a pig house environment multipoint temperature fusion model, wherein pig house environment factor parameters are detected, adjusted and monitored by the CAN bus based pig house environment parameter collection platform, and the pig house environment multipoint temperature fusion model realizes pig house environment multipoint temperature fusion on the basis of support degree fusion weight and grey relational degree fusion weight which are obtained by a support degree matrix and a grey relational degree matrix of temperature fuzzy values of multiple detection point temperature sensors of the pig house environment as well as linear combination weight. According to the system, the problem that regulation and control for the temperature of the pig house environment is greatly affected by the fact that a conventional pig house monitoring system does not detect the temperature of the pig house environment according to the characteristics of nonlinearity and large lag of the pig house environment temperature change, large area of a pig house, complicated temperature change and the like is effectively solved.

Description

technical field [0001] The invention relates to the technical field of agricultural livestock breeding automation equipment, in particular to a CAN bus-based pig house environment temperature detection system. Background technique [0002] The ambient temperature of the pig house has a great influence on the growth of fattening pigs, and pigs of different weights have different weight gain at different temperatures. Low temperature affects the normal growth of fattening pigs, and the maintenance of pigs requires increased feed consumption, high feeding costs, and prolonged fattening periods. The production level and health status of pigs are affected by many environmental factors such as temperature, air, light, dust, noise, equipment and sanitation, among which temperature is considered to be one of the important factors. When the ambient temperature changes, the pig's body will make a series of reactions. When the temperature changes rapidly and the temperature difference...
