摘要：

针对水体重金属污染的监测问题,在光寻址电位传感器的研究基础上,采用无线传感网络技术,设计开发一种用于现场快速检测无线节点.该节点由传感单元、处理单元、通信单元和电源单元4个部分组成.针对无线节点在尺寸和功耗上的特殊要求,处理单元采用了超低功耗的微控制器MSP430FG4619,通信单元采用了体积小、功耗低、集成资源丰富的CC2500作为收发器.实验结果表明,基于铅离子敏感的硫属玻璃光寻址电位传感器的无线节点,在检测含有不同浓度铅离子的水样时,具有良好的响应特性,而且无线通信在短距离内基本稳定,证明设计达到了预期目标.
Abstract:

In order to solve the problem of heavy monitoring in water environment, based on the research of light addressable potentiometric sensor and adopted the technique of wireless sensor network, a wireless node for the on-site and rapid detection was developed. The node consisted of four functional parts which were sensor unit, processor unit, communication unit and power unit. Due to the specific requirements on the dimension and power consumption of wireless node, the processor unit employed ultra-low power micro controller unit MSP430FG4619, while the communication unit the transceiver CC2500 with advantage of tiny size, low power consumption and rich integrated resources. The experiment shows that the wireless node based on Pb2+-sensitive chalcogenide glass light addressable potentiometric sensor has good responses to water samples with different concentrations of Pb2+. The wireless communication within short distance is stable. The design is proven to achieve the desired objective.
