摘要
以具有USB2.0通信功能的Cypress单片机为核心,设计了6路模拟输入,16位数字精度,每路模拟输入采样速率均为250kSPS的数据采集系统。该系统能够在板卡上实现信号的采集及前端处理,并能通过USB总线与上位机通信,实现数据的存储、显示及后端处理。重点阐述了系统硬件原理设计,实现了高速、高精度、高稳定数据采集处理,具有较好的应用价值。
A data acquisition system based on cypress single chip micyoco with USB 2.0 communication is designed. The system has six pieces uL analog input and 16 -bit digital precision,all sampling rate of each analog input is 250 kSPS. It can realize the collection of signal in board panel and front- end processing. It ommunicates with host computer by USB bus in order to realize the data storage , display and backend processing. This pa per puts emphasis on the design of hardware principle and realizes the data acquisition process with high speed, high precision and high stability ,which has good application value.
