基于USB HID类的实时数据采集系统设计

Design of Real-Time Data Acquisition Base of USB HID class

本文提出了一种基于USB HID类的实时数据采集系统,详细地介绍了该实时系统的软件设计方案和固件、硬件设计方案,并给出了实际的测试结果,操作简便、采集数据可靠,效果良好。同传统的数据采集系统相比,该方案使用USB HID类,避免了编写上位机复杂的USB驱动程序,具有无驱动、简单、实时和多路采集处理等优点。

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 muhi- line data acquisition.
