Real-time data collection system and automatic recovery method after interruption of real-time data communication

Abstract

The invention provides a real-time data collection system and an automatic recovery method after interruption of real-time data communication. The method comprises the following steps: an upper collector is connected between an onsite first level machine and a database server via a network, and a data collection interface is arranged in the upper collector; the data collection interface collects data of an OPCServer through an OPC protocol, the data collection interface stores the collected data in a database for cache and backup at first after collecting the data, and then the data collection interface extracts the data from the database and uploads the collected data to the database server for storage by using a TCP; and the data collection interface monitors a data uploading condition, and in the case of data uploading failure caused by an abnormal condition, the data collection interface re-loads the data subjected to uploading failure to the database server. A data cache function is realized on the collection interface, thereby reducing the pressure of the upper collector and the database server.

Description

technical field [0001] The invention relates to the field of real-time data collection and monitoring, in particular to a real-time data collection system and an automatic recovery method for real-time data communication interruption. Background technique [0002] With the development of society, the requirements for production are getting higher and higher. Therefore, in actual production, it is often necessary to monitor and adjust various states and parameters of key links in real time to achieve the ultimate goal. For a real-time operating system, the collected Correctness, frequency, and continuity are indispensable. The real-time nature, complexity, and diversity of engineering determine the importance of continuity. The instantaneous nature of real-time data means that data cannot be imported into the database in time once the power is off or the network is off. to have a huge impact. At present, the minimization of data loss after power failure at home and abroad is...
