Abstract:
The monitoring systems have complex equipments, multiple processes, and complicated control logic in the West-to-East Gas Pipeline which have poor applicability. Therefore, a general mistake-proof control model based on logical judgment was developed to deal with these problems. In this model, the three-hierarchy model mode of process node model, component model and alarm logic model is applied to separate the parser from the three-hierarchy model, so that the mistake-proof logic can be edited and operated independently, and the mistake-proof control platform can be kept safe and applicable. It is shown from its actual operation that this model is highly extendable to meet the requirements of actual engineering application. It provides a new design model and the powerful technical support for the application of subsequent intelligent alarm monitoring platform. (3 Figures, 3 Tables, 21 References)
