針對禽蛋孵化過程中的控制問題，研制了一種以8051單片機為核心新的孵化控制系統，采用不同控制方法，對溫度、濕度和氧氣濃度進行控制，并用間接模糊解耦方法對溫度、濕度和氧氣濃度三者進行解耦，著重闡述了軟件設計思想，并給出了控制算法。系統的實際運行結果表明，該系統動態響應好，控制精度高，并易于各種孵化曲線的實現。

Abstract For the control problem of the incubation process of poultry's egg，an new control incubation system with 8051 microcomputer as the core is developed. the vary control way are selected for temperature and humidity and O2 concentration control, and the indirect fuzzy decoupling is used among temperature and humidity and O2 concentration. in the paper, an intelligent control algorithm is designed, and the software designed way is introduced in detail. Practical running results show it has some advantage, such as good dynamic response, high precision and easy intelligent control.
Key words temperature and humidity control; incubation; fuzzy control; fuzzy decoupling
