Abstract:

Aiming at the problem that the data processing rate of the existing single-chip computer was low, which was not conducive to high-speed data acquisition and processing, this paper studied and designed a high-speed data acquisition and processing system based on single-chip computer control. In data acquisition, A/D high-speed sampling chip was used to achieve high-speed data acquisition. In order to meet the needs of high-speed data processing and storage, this paper used the IDE interface hard disk of PC terminal as the storage device of the system. In addition, in order to coordinate the process of data acquisition and data processing, high-speed dual-port RAM was controlled by single-chip computer core control module to realize high-speed data caching, thus realizing high-speed and non-destructive data transmission from A/D sampling chip to IDE hard disk. The high-speed data acquisition and processing system based on single-chip computer control in this paper was more integrated in data acquisition and data processing, and had high engineering application value.
