Embodiment example

[0046] Background: There are a large number of gas chromatographs scattered in a chemical process industry park. These instruments play a vital role in the normal production of the park. Due to the limitation of quantity, location and professional knowledge, how to ensure the real-time normal operation of all gas chromatographs is indeed a problem. A problem that needs to be solved urgently in the park.

[0047] The process of the method of the present invention to solve this problem is as follows:

[0048]1. Establish the IoT device service layer of the gas chromatograph fault diagnosis architecture

[0049] The device service layer includes the physical entity of the edge computing system, which realizes data collection, local data processing, local data storage, and corresponding operations according to control instructions. Through various embedded sensor nodes in the gas chromatograph, it supports each Real-time intelligent interconnection of such information. According...

Abstract

The invention relates to a gas chromatograph fault diagnosis system structure based on an edge computing framework. The system structure comprises an equipment domain used for acquiring, processing and storing data and executing operation according to a control instruction of a network domain; a network domain used for realizing network protocol conversion between the equipment domain and a data domain; the data domain used for preprocessing and storing the data sent by the network domain and sending the data to the application domain; and the application domain used for carrying out multi-dimensional diagnosis of fault types and fault reasons on a meteorological chromatograph according to the data from the data domain, and carrying out corresponding control on related execution mechanisms. Due to the fact that edge calculation is closer to the gas chromatograph, filtering and analysis of data are achieved at the edge nodes, and therefore accuracy and efficiency are higher.
