基于ZigBee的有害气体信息采集系统设计

摘要

针对石化危险环境下泄露气体信息采集问题,开发了基于无线传感网络技术的多点传感信息采集系统.利用ZigBee协议,通过星形网络实现数据采集和传输,采用串口通信技术与上位机ARM7嵌入式开发系统通信,实现了无线传感器网络在石化气体泄露检测中的应用.%Aiming at the problem of the harmful gas leaking in the petrochemical dangerous environment, a multi-node harmful gases acquisition system based on wireless sensor network technology was presented. By using ZigBee protocol, data acquisition and transformation communicated with supervisory computer through serial port communication technology, data processing and display of the wireless system via ARM7 embedded system was completed. The application of wireless sensor network in petrochemical gas leak detection was achieved .
