在现代工业生产以及科学技术不断发展的过程中,做好数据的采集工作有着非常重要的意义,当前采集系统中的采集方法存在的各种问题,可能会存在安装麻烦以及由于环境的影响而导致采集数据的问题,所以会对中断资源产生限制,不利于进行很好的扩展,但是USB总线控制更好地解决了存在的各种问题,文章分析了主机和小型科学仪器的接口方式,认为通过串行总线就可以实现主机和小型科学仪器(USB)的通信,我们从硬件设计,固件设计,设备驱动设计及应用软件设计的方面对USB总线的数据采集,有利于下一步多台仪器和主机互联的目标。
In the process of continuous development of modern industrial production and science and technology, it is very important to do a good job in data collection. Various problems in the collection methods in the current collection system may cause installation troubles and environmental impacts The problem of collecting data, so there will be restrictions on the interrupt resources, is not conducive to a good expansion, but the USB bus control to better solve the existing problems, the article analyzes the interface between the host and small scientific instruments that the adoption of The serial bus can realize the communication between the host computer and the small scientific instrument (USB). The data collection from the USB bus in terms of hardware design, firmware design, device driver design and application software is conducive to the next multi-instrument and host The goal of the Internet.
