摘要
针对某些场景比如温室大棚或者婴儿房等需要间歇地去采集实时环境信息,而且人工采集的环境信息存在不方便以及错误率高的问题,研究了一种基于红外通信的环境监测系统.该系统以STC89C52单片机为控制核心,主要由红外收发模块、温湿度传感器、蜂鸣器、按键、LCD1602显示屏等外部模块组成,采用常见的NEC红外通信协议.该系统可以实现数据采集,数据调制解调,红外通信,数据显示,报警等功能,可以协助人们更好地查看环境信息.实验验证了该系统低成本、通信稳定,实时传输、抗干扰能力强等特点.
Abstract
Based on some scenes,such as greenhouse or nursery,which need to collect real-time environ-mental information intermittently,and the problems of inconvenient and high error rate of manually collected environmental information,therefore,an environmental monitoring system based on infrared communication is studied.The system uses STC89C52 microcontroller as the control core,and is mainly composed of infra-red transceiver module,temperature and humidity sensor,buzzer,button,LCD1602 display screen and other external modules.It adopts the common NEC infrared communication protocol.The system can realize data acquisition,modulation and demodulation,infrared communication,data display,alarm and other functions,which can help people better view environmental information.The experiment verifies that the system has low cost,stable communication,real-time transmission and strong anti-interference ability.
