基于无线传感器网络的实验室智能监控系统设计

摘要

An intelligent laboratory monitoring control system is designed based on ZigBee wireless communication technique.This system consists of ZigBee wireless data collection nodes and a coordinator.Signals from the sensors can be collected and transferred wirelessly by the ZigBee wireless nodes which contain temperature sensor,hygrometer,smoke transducer,human infrared sensor,relay,flame sensor,photosensitive sensor,etc.The function of the ZigBee coordinator is to receive the data sent by nodes and connect to the upper computer.The data are transferred into the upper computer,and then analyzed and displayed.The development environment of the upper computer is the LabView software.The network used in authors'laboratory proved the effectiveness and feasibility of the proposed intelligent laboratory monitoring control system.%介绍了一种基于ZigBee无线通信技术的实验室智能无线监控系统.该系统由多个ZigBee无线数据采集节点及一个ZigBee协调器组成.ZigBee无线数据采集节点接收温湿度传感器、烟雾传感器、人体红外传感器、继电器、火焰传感器、光敏传感器等采集的数据,并实现无线发送.ZigBee协调器主要实现对各个节点的数据接收,并通过RS232与监控上位机实现连接,将数据传给上位机实现数据的显示、分析与处理.系统采用Labview作为上位机的开发环境,通过网络布点及监控实验,证明了本系统可以有效地对实验室安全进行智能监控.
