基于单片机控制的高速数据采集与处理系统研究

针对现有单片机的数据处理速率较低不利于高速数据采集与处理的问题,文中研究并设计基于单片机控制的高速数据采集与处理系统。在数据采集方面,使用A/D高速采样芯片实现高速数据采集。为满足高速数据处理与存储的需要,文中使用PC终端的IDE接口硬盘作为系统的存储装置。另外,为协调数据采集与数据处理过程,使用单片机核心控制模块控制高速双口RAM实现高速数据缓存排队,从而实现数据从A/D采样芯片到IDE硬盘的高速无损传输。该高速数据采集与处理系统在数据采集、处理方面更加集成化,具有较高的工程应用价值。

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.
