Problems solved by technology

[0005] 2) There are corresponding fault events in each process, such as unqualified material composition indicators, abnormal important process parameters, important equipment operation faults, production operations that do not meet the requirements, etc. These fault events not only affect the production in this process, but also lead to The occurrence of failure events in the subsequent process, which causes problems in the quality of the final product
[0007] At present, the method of finding the root cause of failure events in the process...

Embodiment Construction

[0050] The present invention is described in detail below in conjunction with the specific embodiments of the accompanying drawings.

[0051] In order to automatically and efficiently find and search the root cause of failure events in the production process of products, a cause search system for process industry failure events has been established, such as Figure 1a As shown, it includes: a network server 1 , a data processing server 2 , a client 3 , a real-time database 4 , a historical database 5 , and a system data platform 6 . Any two or more of the above-mentioned various devices may be on the same computer, or may be different devices respectively.

[0052] System data platform 6 refers to the platform for obtaining on-site production process data. It can be connected with the on-site production process control system (such as DCS or PLC) through a communication network (such as industrial Ethernet). Its function is to collect and uniformly manage on-site production Pr...

Abstract

The invention relates to a searching method and system for reasons of a fault event in the process industry. According to the invention, a basic reason resulting in the fault event is automatically searched and sought according to logic and/or time sequence relationship between pre-set fault events and the fault event, and then the basic reason is presented to a monitor to facilitate the monitor to guide the production more effectively.

Description

technical field [0001] The invention relates to a search method and system for the root cause of failure events in the production process of process industry products. Background technique [0002] The process industry mainly adds value to raw materials through physical or chemical operations such as mixing, separating, crushing, and heating. It includes chemical, paper, steel, food, pharmaceutical and other industries. The final product types are solid, liquid, gas and various forms of energy, usually in batch or continuous production. [0003] The production process of process industry products has the following characteristics: [0004] 1) The product production process can be divided into different processes according to the process; [0005] 2) There are corresponding fault events in each process, such as unqualified material composition indicators, abnormal important process parameters, important equipment operation faults, production operations that do not meet the ...
