Asynchronous process data collection system and data collection method

Abstract

The invention discloses an asynchronous process data collection system and a method for realizing process data collection. It adopts a network that supports data packet communication and is used to provide high-speed and large-scale process data communication services; it is connected with the network to provide An active real-time data collection terminal for active real-time process data collection services; a passive idle general-purpose computer system connected to the network for providing process data archiving services; the asynchronous process data collection system is motivated by process, network And the general computer system is a passive idle system. The process data collection method includes: establishing a process data queue, suppressing the process data queue by the data collection terminal, sending the queue, and finally restoring the process data queue. The invention can effectively avoid the uncertainty of the Ethernet communication and the non-real-time performance of the general computer system, and greatly improve the real-time performance and stability of the process data collection system.

Description

technical field [0001] The invention relates to a process data collection system, in particular to an asynchronous process data collection system. The invention also relates to a method for realizing process data collection using the system. Background technique [0002] In order to ensure sufficient, high-speed and accurate process data, support the status monitoring and fault diagnosis of the production process, as well as the tracking, analysis and management of the quality of the production process, the process data collection system is a production process information control system. Basic configuration, very wide application. [0003] Ethernet has the advantages of high transmission speed, low power consumption, easy installation and good compatibility, and supports almost all popular network protocols. A process data collection system based on Ethernet is being widely used. However, the uncertainty of Ethernet communication and the non-real-time nature of general-pu...
