摘要
介绍了一种基于USB通信方式的高速采集分析系统,利用一片8254和两片MAX 1090去采集3路频率量和16路模拟量,然后把采集的数据通过FT245BM发送给PC机。PC机再根据按时、定距以及外触发三种不同的方式,利用预先设置好的各种参数,进行可视化的数据分析处理,并存储于数据库。数据采集、通信和分析三个模块采用并行工作方式。
A high- speed acquisition and analysis system based on USB was introduced in this paper. It utilized one piece of 8254 and two pieces of MAX1090s to acquire the following data： frequencies from three channels and analog signals from sixteen channels, then transmitted them to PC via FF245BM. Finally, according to three different ways of time, distance and outer trigger, PC utilized various parameters that have been set in advance, to process these data in visual way, and stored the result into database. The three modules of data acquisition, communication and analysis can work under parallel order.
