摘　　要：针对室内环境的甲醛和PM2.5的浓度测量与预测的需求,设计基于MEGA2560微控制器和ZigBee的无线监控预测系统。该系统基于数据分析,采用ZigBee、蓝牙等多种无线通信技术通过节点对甲醛、PM2.5进行污染监测,并发送数据到主机。主机对各个节点的数据进行分析,并在人机交互界面上能够显示各个节点的实时污染状态、历史数据、趋势曲线、工作状态等。同时能够在污染物浓度超过阈值时进行报警,通过算法对甲醛、PM2.5浓度进行趋势分析,算出其达到正常值的时间,再以液晶屏显示、语言播报形式提示用户。此外,还能够将以上传至手机上,实现远程监控。实验结果表明,该系统能够实时地监控各个节点的工作运行情况,可以满足室内环境监测的要求。In allusion to the concentration measurement and prediction requirements of the formaldehyde and PM2.5 in the indoor environment,a wireless monitoring and prediction system based on the MEGA2560 microcontroller and ZigBee is de-signed.On the basis of data analysis,the formaldehyde and PM2.5 pollution monitoring is conducted by using nodes and various wireless communication technologies like ZigBee and Bluetooth,and data is sent to the host computer.In the host computer,the data of each node is analyzed,and the real-time pollution state,historical data,trend curve and working state of each node are displayed on the human-machine interaction interface.An alarm is sent out when the pollutant concentration exceeds the thresh-old.Trend analysis of the formaldehyde and PM2.5 concentrations is conducted by using the algorithm.The time of reaching the normal value is calculated.Users are prompted by means of LCD display and language broadcast.The above data is transmitted to the mobile phone to realize remote monitoring.The experimental results show that the system can monitor the working situa-tion of each node in real time,and meet the requirement of indoor environment monitoring.
