基于无线传感器网络的氯气监测系统设计

摘要

Based on wireless self organizing network monitoring system of 433 MHz, signal conditioning circuit, signal acquisition and processing circuit, the power management module and man-machine interface of constant potential electrolytic type chlorine gas sensor are designed, a communication platform based on star topology is built. Problem of monitoring blind spots which comes from the wireless module in lack of battery power status is solved,and the hardware and software design of real-time monitoring system for the chlorine gas content in environment is completed. The system is stable in operation,easy to expand,and has broad application prospects%基于433 MHz的无线自组网监测系统,设计了恒电位电解式氯气传感器的信号调理电路、信号采集和处理电路、电源管理模块、人机交互界面,搭建了基于星状拓扑的通信平台.解决了无线模块中电池欠电状态对监测带来盲点的问题,完成了环境中氯气含量的实时监测系统软硬件设计.该系统运行稳定,易于扩展,具有广阔的应用前景.
