基于ZigBee的远程环境监测人机交互系统设计

Design of ZigBee-based human-computer interactive system for remote environment monitoring

针对传统的室内环境监测系统传输距离短、采集到的数据形式单一且需要进行人工处理的缺陷,设计并实现了一个基于ZigBee的远程环境监测人机交互系统。系统采用模块化的设计方案,整个系统由数据采集终端、ZigBee无线传感网和LabVIEW人机交互界面三部分组成。数据采集终端以STM32微控制器为主控芯片,连接各传感器采集环境数据。数据采集终端通过ZigBee无线传感网和USB转串口模块与上位机通信,上位机通过LabVIEW人机交互界面将数据采集终端测得的环境数据以仪表和折线图的形式显示出来。实验表明,系统稳定性和可扩展性较强、传输距离较远,且无需人工处理即可将每天测得的环境数据以折线图形式直观展现出来,具有一定的科研意义和实用价值。

The traditional indoor environment monitoring system has some defects that its transmission distance is short, and the collected data is in a single form and needs to be processed manually, in order to resolve the defects, a ZigBee-based human-computer interactive system for remote environmental monitoring was designed and implemented. The modular design scheme is used in the system. The entire system consists of three parts： data acquisition terminal, ZigBee wireless sensor net- work and LabVIEW human-computer interactive interface. The data acquisition terminal takes STM32 microcontroller as the main chip to connect sensors and collect environmental data, and communicates with the host computer through ZigBee wireless sensor network module and serial module connecting with USB. The host computer displays the cnvironment data acquired by the data collection terminal in the forms of instrument and broken line graph via LabVIEW human-computer interactive inter- face. The experiment results show that the system has high stability, perfect scalability and long transmission distance, and can display the measured-daily environmental data without manual processing in the form of line chart, which has certain scientific significance and practical value.
