采用DMA方式的中,大容量遥测数据采集与实时处理

本文介绍的遥测数据采集与处理系统能对码速率在480kb/s以内的遥测数据流进行不间断的采集,并在采集的同时完成数据分路、工程单位转换、实时数据显示等数据处理工作,并将数据按规定格式存入外部海量存储器。是一个具有实时处理功能的中、大容量数据采集系统。和其他同类系统相比,该系统硬件结构简单,工作可靠,处理能力强,性能价格比高,并可应用于需要长时间连续采集和处理数据的不同场合。

Medium or Large Capacity Telemetry Data Collecting and Real-Time Processing with DMA Method

This paper introduces a telemetric collecting and processing system which can continually collect telemetric data flow at a data rate within 480k bps, accomplish the tasks of data division, engineer- ing unit transformation and real-time data display, and put the data into large external memory in a designed format. Hence it is a medium or large capacity data collecting system with real-time processing function. Compared with other similar systems, this system enjoys advantages of being simpler in structure, more reliable in performance, stronger in processing ability and higher in performance/cost ratio. It can be used in various circumstances where continual data collection and processing of long duration are performed.
