()
摘要:
为监测航站楼内环境质量,设计了基于WIA-PA环境参数无线实时监测系统。该系统由多个检测节点组网,对航站楼室内各区域CO2浓度及温度进行采集。系统采用STM8作为检测器节点微控制器,通过变周期数据传输机制及WIA-PA协议将采集的航站楼各区域环境参数数据传输到上位机。上位机监测软件通过开辟多线程实现数据可视化显示。实验和应用结果表明,采用变周期数据传输模式,节点功耗可降低66.97%,网络平均丢包率为0.43%。系统功耗低,数据传输稳定。

Design of Distributed Monitoring System for Environmental Parameters of Terminal
()
Abstract:
In order to monitor the environment quality of the terminal, a wireless real-time environment parameters monitoring system based on WIA-PA is designed. The system is set up by multiple detection nodes, and the CO2 concentration and temperature of the indoor area of the terminal are collected. It uses STM8 as the detector node micro controller, and transects the environmental parameters data of the collected terminals to the host computer through the variable period data transmission mechanism and WIA-PA protocol. The monitoring software of the upper computer realizes the visualization of data by multiple threads. The experimental and application results indicate the power consumption of nodes by variable cycle acquisition can be reduced by 66.97%, and the average packet loss rate of network is 0.43%,reveling the fact that low power consumption and the stable data transmission.
Key words:  Environmental monitoring  WIA-PA  Variable cycle acquisition  Multithread  Data display
