Abstract

The invention discloses a method and a device for synchronously collecting data among modules of a distributed system in real time. The method comprises the following steps: collecting data of each module and data of a power supply in the distributed system in real time; processing data of each module by taking power supply data as a reference; and carrying out synchronous processing on the processed data of each module. According to the invention, the data collected by each module of the distributed system takes a device power supply as a reference, and the synchronous collection does not depend on an external clock source, so that the engineering construction difficulty is reduced, the reliability of the system is improved, and the structure of the monitoring system is optimized.

Description

technical field [0001] The invention relates to the technical field of distributed system industrial control, in particular to a method and device for real-time synchronous data collection among distributed system modules. Background technique [0002] The problem of synchronous acquisition of precise signals in distributed systems in the field of industrial control has always been a concern. At present, external clock source synchronization technology is generally used to achieve synchronous data acquisition, and the scheme structure is complex and costly. [0003] For example, in the on-line monitoring system of zinc oxide arrester, the calculation of resistive current needs to measure the voltage and leakage current of metal oxide arrester (MOA) simultaneously. Since the positions for measuring the MOA voltage and the leakage current are far apart, it is difficult to accurately and synchronously collect the MOA voltage and leakage current, resulting in the inability to ac...
