摘　　要：为了实现对化工生产过程中有害气体的监测,以ATmega16单片机为核心构成数据采集器,通过以太网组成有害气体智能监测系统。数据采集器利用多种气体传感器检测各类有害气体,使用ATmega16单片机完成多通道数据实时检测处理,实现有害气体浓度实时检测、显示和超限报警功能。同时可通过以太网实现数据采集器与PC机的通信,从而建立数据库实现有害气体浓度数据的在线检测和分析处理。实验表明,系统电路结构简单、工作稳定可靠、精度高,具有较高的性价比和实用性。To monitor harmful gases in chemical engineering process, this intelligent monitoring system used core SCM AT-mega16 as data collector with the help of Ethernet. With the data collector detecting various of harmful gases using various sensors and the ATmega16 SCM processing multi-channel data in real-time, the system can detect harmful gases, display and alert. Meanwhile,it communicates data collector with PC through Ethernet, and establishes database to sense and analyze harmful gases concentration data online. Experiments show that the system has simple circuit structure, and it is stable, reliable, precise, and it has high cost performance and practicability.
