摘要
数据采集技术在自动控制、电气测量、航空航天等工程实际中有着极为广泛的应用。USB以其接口容易、传输速度快、支持热插拔的优点,成为数据采集技术的研究热点。通过介绍以DSP为微处理器,以Philips公司的ISP1581作为USB收发控制芯片的硬件及固件程序设计方案。对系统调试中存在的问题进行了分析和总结,并提出了改进的措施。证明将USB与DSP相结合是进行高速数据采集,处理与传输的理想解决方案。
In some field, such as auto-control, electric measure, spaceflight projects an so on, data acquisition technology is used widely. USB has the characteristics of easy to use, high speed and supporting to cut in or pull out on-line, it becomes a trend in data acquisition technology. To introduce the hardware and firmware design, selecting DSP for microprocessor control chip and Philip Corporation＇s ISP1581 for USB receiver/transfer control chip. To introduce the problems during the debugging are analyzed and summarized, some measures about the system improvement are proposed. Thus, combining USB and DSP is an effective solution to data acquisition with high speed as well as processing and transmitting.
