摘要：

针对夏季高温对奶牛的不利影响，本文对适合应用于牛舍的喷淋降温系统的控制部分进行了研究。根据奶牛的生理特性，该控制系统以温湿指数(THI）为主控参数，结合时间控制参数等，编制的定时控制喷淋降温模式，能使奶牛生活环境得到更为合理的控制，能更加有效的减轻奶牛热应激。本文对该控制系统软硬件设计的主要内容进行了阐述。该控制系统主要采用单片机技术来完成对喷淋降温设备的控制，其研究主要包括单片机控制单元和动力驱动单元的设计。单片机控制单元以AT89S52单片机为核心，通过设计的外围电路及编写的功能程序实现对动力驱动单元的控制；动力驱动单元通过线路的设计布置，实现喷淋模式中降温设备的交替运行功能，从而对喷淋降温设备进行直接控制。

Abstract:

Against the bad effects of high temperature to dairy cows, this paper makes a further study on the control of sprinkling system for cooling dairy cows. According to the life style of dairy cows, this study realizes the control of sprinkling system through controlling mode, which uses temperature-humidity index (THI) as a chief control parameter, also adding time parameter, thus efficiently reducing cow’s heat stress.This paper presents main part of hardware and software design of the controlling system.The control system was developed with Single-Chip Microcomputer technology, consisting of controlling part and power driving part. The MCU of controlling part adopts AT89S52 microcomputer, and the peripheral circuits include power supply, data gathering and memory, AD converter, real time chip, LED display, keyboard scanning and relay driving module; The power driving part mainly designs the alternate-running sprinkling mode, realizing the direct control of cooling equipment..
