| 英文摘要 | 为了解决传统分光光度计分析速度慢、体积大、成本高的问题,设计了一种基于uSb接口的新型紫外分光光度计的数据采集卡.该采集卡采用带uSb内核的芯片Cy7C68013,集成了串行口引擎、从属fIfO等模块;以CPld芯片IS-PMATCH4064V作为时钟同步接口,产生CCd驱动时序,满足了数据采集的高频要求;AdC采用AdS803,具有12位精度与5 MHz的采样率.开发的软件主要包括固件下载驱动、封装好的上下层接口功能函数、CPld固件.实验结果表明,该采集卡稳定可靠、接口函数简单通用,采集卡速率达到16 Mb/S.; A novel data acquisition card,based on USB bus,is proposed to resolve the disadvantages of the traditional spectrometer,such as low efficiency,poor portability,and so on.In the article,the design of hardware is described first.In the data acquisition card,chip CY7C68013 is utilized which includes Serial Interface Engine and Slave FIFO.The CPLD ISPMATCH4064V being used as Synchronous Clock will drive the CCD.ADS803,which has 12 bit and 5 MHz Sample Rate,is utilized to the A/D converter.And then the development of software is discussed.The software includes firmware、the interface functions between application and driver、the circuit function model of CPLD.It is shown that the speed of the data acquisition can attach to 16 Mb/s,and the card is stable and reliable. |
