本文介绍了分布式微机大规模ＤＡＳ实现技术。主要包括数据共享和统一管理基础、参数表驱动技术、采集量扩展技术、优化的取数方式、脱机数据采集、数据处理过程中的选点和处理次序的确定、处理结果共享及多道多重处理中的相关通道指定技术。利用这些技术，以ＰＣ机为主控机所建立的大规模ＤＡＳ，同现行的以小型机为主控机的大规模ＤＡＳ相比，数据采集能力相当，而数据处理的速度却远快于后者，系统的管理和使用也简单得多，并且大幅度地降低了系统的成本。
This article introduces the distributed microcomputer large-scale DAS implementation technology. Mainly includes the basis of data sharing and unified management, parameter table driver technology, acquisition volume expansion technology, optimized access method, off-line data collection, data processing points in the process of selecting and processing to determine the sequence, the sharing of results and multi-channel multiple The relevant channel in processing is assigned technology. Using these technologies, a large-scale DAS built with a PC as the master is comparable in data acquisition capabilities to the current large-scale DAS with a minicomputer as the master and the data processing is much faster than the latter The system is also much simpler to manage and use, and drastically reduces the cost of the system.
