Embodiment Construction

[0022] (1) Detection node design

[0023] The detection unit is composed of temperature and humidity sensor data acquisition circuit, signal conditioning circuit, communication interface and C8051F020 single-chip computer. The THT-N163A temperature and humidity transmitter is used to collect the environmental temperature and humidity of the chicken house, which is amplified by the signal conditioning circuit and sent to the C8051F020 single-chip microcomputer. The communication interface is composed of CAN protocol chip SJA1000, photoelectric isolation circuit, anti-interference circuit and transceiver circuit. The communication port, the control node communication port, CAN / 232 and the field monitoring computer constitute the CAN bus communication network to realize the communication between the field monitoring computer and the detection node and the control node. The system uses the CAN / RS232 module to realize the protocol conversion between the field monitoring computer and...

Abstract

The invention discloses a CAN bus-based barton environment temperature control system, which comprises three parts, namely a data acquisition and control platform, an intelligent barton breeding environment temperature control system and an expert system for setting an ideal temperature value. Aiming at the characteristics of non-linearity, great inertia, great time-lag and time-dependent nature as well as the problem of control difficulty of barton breeding environment temperature change, the invention designs the CAN field bus-based barton breeding environment temperature control system, which is a field bus monitoring system for realizing detection, intelligent control and management on breeding environment temperature through the data acquisition and control platform, the intelligent barton breeding environment temperature control system and the expert system for setting the ideal temperature value, and the requirement of farmers on improving economic benefit through high-quality and high-efficiency control over the barton breeding environment temperature is met, so that the system has great popularization value.

Description

technical field [0001] The invention relates to the technical field of intelligent control equipment for the environmental temperature of chicken coops, in particular to a CAN bus-based environmental temperature control system for chicken coops. Background technique [0002] A suitable environment is the condition to ensure the normal production performance of the chicken flock. The ventilation and cooling conditions of the laying hen house in summer directly affect the production performance of the laying hens, because high temperature seriously affects the feed intake and feed conversion rate, weight gain and Egg production performance, etc., and even lead to death. When the ambient temperature of laying hens is controlled at 21°C-25°C, the feed conversion rate and egg production rate are the highest; The feeding center of the brain is affected, so that the feed intake decreases, resulting in insufficient intake of nutrients, resulting in a decrease in egg production, sma...
