摘要
介绍了基于USB总线集成芯片CH371的数据采集系统的开发方法,包括硬件设计及应用软件的设计,同时也介绍了CH371的结构与特点。USB接口应用到数据采集系统中,提高了数据采集系统的速度,增强了系统的抗干扰能力和数据传输的可靠性,克服了使用数据采集卡带来的诸多问题,该系统还可与MAX485结合来实现数据信息处理。特别是随着USB2.0的推出,USB的高传输速率必将使其在数据采集系统中的优势更加明显,同时会使其在更广阔的领域得到更深层次地应用。
Introduced a method to empolder the data acquisition system based on the chip CH371 of USB, including the design of hardware and application software, At the same time, the structure and characteristic of CH371 was introduced. To apply the interface of USB to the data acquisition, system can increase the speed of data acquisition system, can strengthen the ability of anti-jamming and reliability of data transmission. The system conquered many problems of using the card of data acquisition, and realized telematic by joining together the usage with the MAX485. Especially negotiate along with the USB 2.0 of release, the USB advantage of high baud rate is more obvious in the data acquisition system,it will widely use in the more deep level of structure at the same time.
