摘要
选用便携式计算机的并行接口与串行接口电路板作为实时数据采集的信道.分析了它与接口板的数据传输原理,编制了实时数据采集程序,介绍了它们间的引线技巧.现场应用表明,该方法简便可靠.
Real time data acquisition, processing and storage are difficult in some places that lack alternating-current power supply to micro-computers. The portable computer is small in size, light in weight and powered by battery, and is suitable for some special cases. However, many portable computers has no bus slot, and the normal interface circuit board can not be used for real time data acquisition and processing. Parallel and serial ports of portable 昪omputer are used as signal channels for real time data acquisition. The principle of data communication from the channels to interface circuit board is analyzed. A real time data acquisition program is developed, and the connection method is introduced. Its application is simple, convenient and reliable.
