【摘要】 设计了用于饮用水取水口急性毒物监测的无线传感器网络系统.论述了青海弧菌Q67的发光机理并以其为基础构成生物传感器;弱光检测采用光敏元件.由于水温不同可能会给监测结果带来影响,因而采用DS18B20温度传感器监测温度.无线传感器网络的节点由无线收发模块CC2420和单片机Atmega128组成.无线传感器网络的通信协议选择ZigBee协议.对系统进行了取水环境的测试实验并对数据进行了分析探讨.更多还原

【Abstract】 A kind of wireless sensor networks to monitor acute toxicity in water supply was described based on the luminescent principle of V.Qing-haiensis Q67 and the biosensor constructed.The weak luminescence was measured by photoactive element.Because the variations of water temperature might affect the monitoring result,DS18B20 temperature sensor was used to detect temperature.The node of wireless sensor network was consisted of CC2420 and Atmega128,and the communication protocol of WSN was ZigBee.更多还原
