基于FPGA的煤粉浓度测量系统设计

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。

Design of pulverized coal concentration measurement system based on FPGA

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.
