摘要
煤粉浓度对电厂发电效率具有直接影响,基于可编程逻辑门阵列(FPGA),设计了测量煤粉浓度的双通道数据采集系统。系统以Altera公司的CycloneⅡ代FPGA为主控制芯片,通过控制AD9223模数转换器,实现数据转换;采用Cypress公司的CY7C68013A芯片,以及Slave-FIFO方式存储时序,通过USB实现转换的数据与计算机之间的传输。采用LabVIEW软件完成上位机数据采集界面的设计。系统实现了对煤粉浓度微弱变化的测量与控制,有效提高了煤粉的燃烧效率。
For pulverized coal concentration has a direct impact on the efficiency of power plants, a dual-channel data acquisition system based on Field Programmable Gate Array（FPGA） is designed to measure the pulverized coal concentration. The system utilizes Cyclone II FPGA of Altera and AD9223 analog-digital converter to realize data conversion. CY7C68013A of Cypress is chosen to realize the converted data transmission between computers by USB through Slave-FIFO. Finally, the PC data acquisition interface is designed on LabVIEW and experimental results show that the combustion efficiency of pulverized coal is effectively improved.
