| 摘 要： | 通过LabVIEW平台开发了SO2浓度在线监测技术，并设计了SO2浓度在线报警系统。系统主要由传感器、LabVIEW控制面板、PCI-1200数据采集卡、报警电路组成。通过传感器和PCI-1200数据采集卡将SO2浓度监测信号转变成数字信号输出，采用三极管将数字信号放大，转换为声音报警信号。

| Abstract: | Sulfur dioxide online monitoring technology was developed based on LabVIEW,and the alarming system was designed.The system was mainly composed of sensor,control panel of LabVIEW,PCI-1200 data collection card,and alarming circuit.The monitoring signal of sulfur dioxide concentration was transformed to digital signal by sensor and PCI-1200 data collection card to output.The digital signal was enlarged by dynatron,and then transformed to sound warning signal. |
