基于单片机的配电房温湿度测控系统设计摘 要为保证电气设备在配电房的安全运行,设计了一个基于 ATC89C51 单片机作为控制器的温湿度测控系统,本文首先介绍了系统的总体方案设计,然后详细介绍了各部分硬件及软件的设计,硬件部分包括串行通信电路、系统电源、人机交互界面、控制部分及输出部分。软件部分采纳汇编语言进行编写,给出了详细的流程图及部分子程序的设计。实践表明,该系统工作稳定,抗干扰能力强,具有良好的性价比和应用价值,能实现自动控制、手动控制和报警功能,并且对于其它领域的温湿度测控系统的设计也有着较高的参考价值。关键词:温湿测控;ATC89C51;配电房ABSTRACTDesign of Temperature and Humidity measurement and Control system based on ATC89C51 is for the purpose of guaranteeing electric equipment run safely in the switching house .First we give the general plan of the design . Detailed techniques will be presented to describe every part of the design of the hardare and software.For the hardware, it includes the serial communication circuit、the system power supply 、the human-computer interaction interface 、the control system and the output part. For the software, we use assemble language and give detailed flow chart and some designs of subprogram .The practice showed that the system works stabilization well anti-interfere ,high performance price ratio and application value,has auto-control、Manual control、alarming bare implemented in the system and also available for reference to design of other fields of Temperature and Humidity measure and control system instructions.KEY WORDS : temperature and humidity measure and control, ATC89C51, The Switching House目录摘 要..........................................................................................................................................I目录...................................................................................................................................
