本文提出了一種基于USB HID 類(lèi)的實(shí)時(shí)數(shù)據(jù)采集系統(tǒng)，詳細(xì)地介紹了該實(shí)時(shí)系統(tǒng)
的軟件設(shè)計(jì)方案和固件、硬件設(shè)計(jì)方案，并給出了實(shí)際的測(cè)試結(jié)果，操作簡(jiǎn)便、采集數(shù)據(jù)可靠，效果良好。同傳統(tǒng)的數(shù)據(jù)采集系統(tǒng)相比，該方案使用USB HID類(lèi)，避免了編寫(xiě)上位機(jī)復(fù)雜的 USB 驅(qū)動(dòng)程序，具有無(wú)驅(qū)動(dòng)、簡(jiǎn)單、實(shí)時(shí)和多路采集處理等優(yōu)點(diǎn)。

Abstract: This paper presents the design of a data acquisition system base on the
USB HID class, and details the software structure, firmware and hardware structure,
and gives the result of test in operation, meanwhile, operation is simple and
convenient, and data acquisition is reliable, and the effect is wonderful. Compared
with traditional data acquisition system, this scheme employs USB HID class, no need
of designing complex USB drivers program on PC, and it has the virtue of driverless,
simple, real-time and multi-line data acquisition.
