基于无线传感网的环境监测系统

Environmental Monitoring System Based on Wireless Sensor Network

针对传统的环境监测系统有线传输布线和维护不便、施工周期长且不便扩展等缺陷,设计一种基于Zig Bee无线传感网的环境安全监测系统.数据采集节点以CC2530芯片为核心,对温湿度、烟雾浓度、空气粉尘浓度、甲醛浓度等环境参数进行采集并发送,以嵌入式微处理器为主控的协调器模块接收环境参数数据并处理后,通过WiFi上传至上位机和云服务器.实验结果表明,系统工作稳定、安装维护方便、可扩展性强,实现环境参数数据可靠传输,具有较高实用价值.

An environmental security monitoring system based on ZigBee wireless sensor network was designed in view of the shortcomings of the traditional environmental monitoring system, e.g. wiring, maintenance, long construction cycle and inconvenient expansion. The data collection node took the CC2530 chip as the core, collecting and transmitting the environmental parameters, e.g. temperature and humidity, smoke concentration, air dust concentration, formaldehyde concentration, etc. The coordinator module controlled by embedded microprocessor received the environmental parameters data and uploaded them to the host computer and cloud server through WiFi after processing. The experimental results showed that the system is stable, easy to install and maintain, and has strong expansibility. It can achieve reliable transmission of environmental parameter data and has high practical value.
