| Abstract: | This paper presents a high speed data sampling system based on the ISA bus of an industrial control computer.The interface between a high speed single chip computer and PC is realized by using the ISA bus.The hardware mainly uses the I/O interface and interruption technology.The system makes a feature of using the high speed single chip computer to perform its high speed data sampling with the frequency up to 1M to 2MHz.The experiment shows that the system has high reliability,high anti interference and low cost. |
