Data high-speed collection method based on industrial internet platform

Abstract

The invention provides a data high-speed collection method based on an industrial internet platform. The method comprises the following steps: collecting a measurement signal in the production processing by adopting RT and IRT real-time channels of a PROFINET protocol and using a standard Ethernet interface; and then performing data format conversion, developing a cache area, converting the produced original data by adopting a producer-consumer model, and then transmitting the data to a cloud server on the industrial internet platform to store. Through the data high-speed collection method provided by the invention, the data can be collected in high-speed by adopting the standard Ethernet interface, the communication period in 1-10ms level is acquired, and the data is transmitted to the industrial internet platform.

Description

technical field [0001] The invention relates to a high-speed data collection method based on an industrial Internet platform, in particular to high-speed thickness difference data collection during nonferrous metal processing, and belongs to the technical field of nonferrous metal processing control. Background technique [0002] During the rolling process of non-ferrous metals, a large amount of process data and performance index data are generated, such as pressure, flow, temperature, thickness difference, plate shape, surface quality, tissue performance and other data. These data interact and influence each other, representing the metal The characteristic parameters of the processing process are of great significance and value to the quality of the final product and the use effect of the end user. Among all these data, the thickness difference refers to the difference between the target thickness and the actual measured thickness, which has always been emphasized and valu...

Problems solved by technology

[0003] In the traditional processing process, there are two main ways to collect thickness difference data: one is to use a professional data acquisition board developed by a large company and use an analog input channel. This method has a high acquisition rate but is very expensive; Another method is to use the conventional Ethernet interface and use the OPC communication method. This method has a lower cost, but the acquisition rate is also lower. Although it can meet the judgment requirements of thickness difference performance indicators under certain conditions, it is not suitable for high-speed applications such as fault diagnosis. However, the requirements cannot be fully met

[0004] Moreover, whether it is a professional acquisition board or a conventional OPC communication, the traditional thickness difference data acquisition generally adopts the format of a data file, which is stored in the local computer and is not transmitted to the industrial Internet platform.
