|
摘要
针对重型采煤机在线状态监测对信号采集的需求,提出了一种基于CPCIe架构的高速多通道信号采集板卡的设计方案。方案中使用了Xilinx公司Virtex-6系列的FPGA为主控制器,以TI公司推出的高性能双通道ADC、DAC芯片为信号采集回放单元,结合多片大容量的DDR3 SDRAM作为高速缓存单元,采用FPGA内部集成的PCIe硬核解决方案来构建CPCIe总线接口单元。对信号采集板卡的软硬件设计进行详细的介绍,并进行了仿真测试。实验验证,板卡最高可以在100MHz采样频率下同时对4路模拟量信号进行采集和传输,PCIe接口数据上传速率不低于800 MB/s;该板卡具有易于升级、灵活性强、应用广泛的特点。
For requirements for signal online acquisition of heavy shearer,this paper presents a design scheme of high speed multi-channel signal acquisition board based on CPCIe architecture. The scheme uses FPGA of virtex-6 series as the main controller,which is produced by Xilinx company. And this scheme uses high performance dual channel ADC,DAC conversion chip as the signal collecting and reading unit,combining with many pieces of large capacity DDR3 SDRAM as the cache unit. With the use PCIe hard solutions internal integrated in FPGA,the CPCIe bus interface unit has been constructed. In this paper,the hardware and software of the signal acquisition board are introduced in detail and a comprehensive simulation,testing and validation are carried out. Experiments verified that the board can process simultaneously 4 channel analog signal acquisition and transmission at 100 MHz sampling frequency,and the rate of the PCIe interface data upload is not less than 800 MB/s. This board is easy upgraded and flexible,and can be widely used.
