A detection method and system for intelligent tuning of process control

Abstract

The invention discloses a detection method and system for intelligently tuning process control. The detection method includes the following steps: acquiring the running standard and the running targetof a process control system; determining the time constraint conditions for task running according to the running standard and the running target; judging whether the process control system can run steadily or not, if the process control system cannot run steadily, correcting the running standard and the running target of the process control system through an intelligent instrument, otherwise, selecting an input parameter interval of PID adjustment; dynamically testing the process control system according to the input parameter interval to get a test result; and judging whether the test result satisfies the test requirement, if the test result does not satisfy the test requirement, correcting the input parameter interval of PID adjustment, otherwise, analyzing the test result to get a detection report. Intelligent tuning is combined with the use target of process control. The conditions and changes in various scenarios and the influence of all links are fully considered. Thus, the detection result is more accurate.

Description

technical field [0001] The invention relates to the technical field of industrial process control and instrument measurement, in particular to a detection method and system for intelligent setting of process control. Background technique [0002] Process control is widely used in the production and operation of the process industry. In the detection and control of the production process, in order to realize the predetermined control scheme, it is necessary to set the adjustment parameters at the beginning of the system operation. This process is an indispensable and important work step for all kinds of instruments. After the smart instrument is adopted, this kind of work can be divided into two categories: one is the parameter setting directly carried out on-site in the process pipeline, and the instrument sensor is directly installed in the process pipeline or equipment, also known as in-situ process control; the other is The class is to realize remote parameter setting th...

Problems solved by technology

[0005] (1) The overall lack of detection schemes for intelligent tuning: various detection bases (such as various standards) are mainly aimed at conventional instruments and control processes, and there is no specific detection method for the process control of intelligent instruments, especially including the bus communication part. The detection of the situation will inevitably lead to non-standardization and non-standardization

[0006] (2) Smart tuning indicators cannot reflect the impact of potential behavior on the system: smart tuning indicators are either not connected with the evaluation objectives, or too many indicators exist abstractly out of constraints, so that it cannot comprehensively reflect the system impact, or cannot be reliable accurately reflect the complex and changeable system behavior effects

[0007] (3) The detection process is mainly based on a single machine, without considering the influence of the network node of the smart instrument: the current detection method is more researched on the conventional instrument, and there are deficiencies in the network, which makes the detection universality not strong, and the detection process is not repeatable , so that the test results lack consistency and certainty

[0008] (4) The test method lacks the consideration of dynamic parameter adjustment, repeated improvement and equipment efficiency: because the evaluation purpose is centered, the evaluation of the instrument process control with intelligent functions lacks the consideration of intelligent characteristics (such as dynamics), and needs to be continuously improved and further development
