Problems solved by technology

At the same time, due to ignoring the data between polling cycles, transient events will be missing, resulting in no correlation between events
The current implementation also results in no direct correlation between events and states
making it impossible to do more advanced analytics

Embodiment 1

[0042] A common situation encountered in a power generation production environment is that unit outages are divided into planned and unplanned outages. Planned shutdown refers to the gradual shutdown at a specified time according to the maintenance or operation plan. Unplanned downtime is the threat of a major failure of the unit continuing to operate, quickly cutting off the unit load. Accurate capture of unplanned downtime events is extremely important for analyzing the cause of failures. Not only can the unplanned shutdown notice be sent to the relevant person in charge in a timely manner, and the consequences of the problem can be dealt with in a timely manner, but also the system operating parameters can be analyzed forward according to the failure time point to find the cause of the problem.

[0043] For planned shutdown and unplanned shutdown of the unit, two tracking events, planned shutdown and unplanned shutdown, can be specified. In specific use, states related to...

Abstract

The invention discloses a method and a system for acquiring definable events and states of equipment in real time based on message flow. The numerical value change message flow of a measuring point is processed and converted into equipment events and state messages in real time. By establishing an equipment event model, definition and processing judgment logic of equipment events and states needing to be tracked are guaranteed, equipment event conditions capable of customizing business logic are judged in real time by monitoring messages of real-time numerical values of measuring points, and equipment records and equipment event messages are generated. The real-time performance, continuity and integrity of recording of equipment events are guaranteed by analyzing the measuring point data one by one in real time, the equipment events and the equipment states are organically combined, the system processing pressure is reduced, rapid and universal implementation of efficiently collecting the equipment operation events and states in real time according to the measuring point values is provided, and the system performance is improved. And the accuracy and the response speed of the business processing data are improved. And an accurate and reliable data basis is provided for service processing based on the equipment event.

Description

technical field [0001] The invention relates to the technical field of industrial control, in particular to a method and a system for collecting device definable events and states based on a message flow in real time. Background technique [0002] In the industrial field, the value of the measurement point is transmitted in real time through the sensor DCS measurement point, which is widely used in the detection and monitoring of the production operation environment. The operation status of the current production environment can be displayed in real time through tools such as configuration diagrams. [0003] In reality, more analysis is often required from the measurement point data, such as analyzing the equipment operating conditions reflected by the measurement points. The device health status includes the device's operating status and events. By capturing the operating status and events of the equipment through the numerical value of the measurement point data, it is po...
