摘要
针对目前室内有害气体在线监控系统的研究现状,结合无线传感网络自身的特点,给出一种基于ZigBee的室内有害气体在线监控方案,该方案将无线传感网络与传统网络管理相结合,采用基于802.15.4/ZigBee的无线传感网络技术及嵌入式技术,设计并实现基于ZigBee的室内有害气体在线监控.提出了一种气体传感器前置放大电路设计方案,具有抗干扰能力强、共模抑制比高、设计简单、成本低廉等特性.实验结果表明,系统可有效地对局部无线网络中的数据进行实时采集和处理,实现对室内环境中有害气体的监控.
Aiming at the current research status of on-line monitoring system for indoor harmful gas, combined with the characteristics of wireless sensor network itself, this paper gives a method of indoor harmful gas line monitoring based on ZigBee. The programme will be combined with traditional network management in wireless sensor networks, adapting to technology of wireless sensor network bases on the protocol 802. 15.4/ZigBee and the Embedded System. Design and re- alization of indoor harmful gas line monitoring based on ZigBee. A pre-amplifier circuit design for a gas sensor is made with strong anti-interference ability, common-mode rejection ratio, simple design, low cost and other features. Experi- mental results indicate that the system can be effective in the local wireless network of real-time data acquisition and processing, realization on the monitoring of harmful gas in the indoor environment.
