基于GPIF模式的电子舌数据采集系统设计

摘要

Electronic tongue has a wide range of application in the field of artificial taste recognition, but it needs numerous data to be collected. In the new design of volt-ampere electronic tongue system, a high-speed data acquisition program based on GPIF mode is proposed. CYPRESS' CY7C68013A was selected for USB receiver/transfer control chip, then the high-speed AD chip AD7492-5 was connected by this series of chip's specific GPIF interface mode, finally the GPIF waveform was designed through waveform editor and the communication program was written in C language, so the high-speed data transmission between the electronic tongue and computer could be achieved. The experiments show that the system can realize high speed, real-time storage and process for mass data.%电子舌在人工味觉识别领域有着广泛的应用,但电子舌采集数据量庞大,在新型伏安电子舌系统设计中,提出了一种基于GPIF模式的高速数据采集传输方案.该方案采用CYPRESS的CY7C68013A作为USB收发控制芯片,并利用此系列芯片特有的GPIF接口模式与高速AD芯片AD7492-5相连,通过波形编辑器设计GPIF波形,使用C语言编写通信程序,实现了电子舌与计算机之间数据的高速传输.经实验证明,该系统能使大量数据得到更加快速、实时的存储与处理.
