用于蠕变试验机的集散型数据采集系统设计

Design of Distributed Data Acquisition System for Creep Testing Machine

本文介绍了一种基于串行总线的新型蠕变变形测量系统,最多可以采集64台蠕变试验机的变形数据,也就是集散型控制理念的实例化。本系统的使用保证了所有蠕变试验机变形数据的准确性和完整性,在整个试验过程中能够自动采集和存储,并且能够通过计算机命令进行设置,极大地提高了蠕变试验的自动化程度和可靠性。

A kind of data acquisition system for creep deformation based on serial bus is introduced in this paper. The system can collect at most the deformation data of 64 creep testing machines, and it is the instantiation of the concept of distributed control. The system can ensure the accuracy and integrity of deformation data of all creep testing machine, and can automatically collect and store the deformation data in the testing process. The parameters can be set by computer, which greatly improves the automation and reliability of the creep test.
