基于射频技术的无线环境监测系统设计与实现

摘要

随着射频技术的日益成熟,文中提出了一种无线的环境监测系统。本系统分为1个主机和2个从机,从机利用传感器采集现场房间温度、湿度和空气污染程度等环境参数,利用LCD12864实时显示,并通过nRF905无线通信模块发送采集的环境参数。在主控室主机和计算机终端串口相连,在计算机上通过监测软件实时显示各个房间的各种环境参数,并且还具有报警功能。该系统性能稳定,抗干扰能力强,搭建方便,在现实生活中有很强的实用性。%As the RF technology is ripe day by day, this paper presents a kind design of the wireless environment monitoring system. The system consists of a host and two slaves.Every slave uses sensors to collecting room environmental parameter, through the nRF905 wireless communication module to realize the data sending and receiving, using LCD12864 real-time display of temperature information. In the main control room by the computer terminal through management software real-time display, test the temperature of each room, and also has the alarm function. The system has stable performance, strong antiinterference ability, build a convenient, practical intelligent building has a strong practical.
