| 中文摘要: |
| 电站锅炉煤粉颗粒参数在线监控对于锅炉优化控制有着重要的参考作用.为了实现煤粉管道内颗粒的细度、浓度、速度的实时监控,通过模块化的程序设计方案,设计了数据采集系统的上位机软件.该软件通过自定义控件实现了系统组态、实时曲线与柱状图数据显示、保存等功能.同时利用多线程和通道自动分配方法实现了单通道采样频率达1 MHz的数据快速采集与处理,并基于Modbus通讯协议实现了与DCS(Distributed Control System)的即时通讯.在电站长时间投入运行的结果表明,该系统具有良好的稳定性与可靠性,各项功能均满足锅炉运行与优化控制要求. |

| Online monitoring of pulverized coal in boiler provides the importance reference for optimal control of power station boiler.In order to realize the remote monitoring of particle size,concentration,and velocity of pulverized coal,the upper-computer software of data acquisition system was designed by using modular program design method.This software could realize the system configuration,real-time curve and histogram displaying,data storage,and so on.Each data acquisition and processing channel with 1 MHz sampling frequency was achieved by using multi-thread technology and automatic allocation simultaneously.The capability of real-time communication with the Distributed Control System (DCS) based on the Modbus communication protocol was achieved.The practical runs shown high stability and reliability of this software.And it could meet the demands of operation and optimizing control of boiler well. |
