摘要
以流动注射分析系统为核心、LabVIEW为软件开发平台,设计了锅炉水总碱度在线检测系统。通过LabVIEW平台,实时采集流动注射分析系统中由pH电极测得的电压值并对采集到的信号进行分析和处理。根据流动注射分析峰的面积与锅炉水总碱度对数之间的线性关系,通过计算得到锅炉水的总碱度。运行测试结果表明,该系统测量精度高、可扩展性强、操作简单、人机界面友好,可在线、实时、有效、快速地测定锅炉水总碱度。
The on-line detecting system for total alkalinity in boiler water is designed with flow injection analysis （FIA） system as the core and LabVIEW as software developing platform.The voltage values that measured by the pH electrode in FIA system are acquired in real time through the LabVIEW platform,and the acquired signals are analyzed and processed.In accordance with the linear relationship between the peak area of FIA and the logarithm of the total alkalinity in boiler water,the total alkalinity in boiler water can be determined.The test result shows that the system features high precision,good extensibility,simply operation and user-friendly interface; it implements online,effective and rapid measurement in real time for the total alkalinity in boiler water.
