A plant-wide monitoring system and monitoring method for loop performance evaluation

Abstract

The invention provides a plant-wide monitoring system for loop performance evaluation, the system includes a plant-wide monitoring server, data communication components and several PID performance evaluation workstations, the plant-wide monitoring server includes a configuration software module and a plant-wide monitoring service module ; The plant-wide monitoring server sends a command request to the PID performance evaluation workstation through the data communication component, and the designated PID performance assessment workstation collects the relevant data of the controlled device according to the call request, and returns it to the whole plant through the data communication component The monitoring server performs analysis and processing. The plant-wide monitoring system and monitoring method for loop performance evaluation proposed by the present invention can summarize and display the real-time evaluation and statistical results of multiple sets of devices scattered under different operating departments, and can effectively solve the current single-node PID performance evaluation software It is difficult to realize the deficiency of whole plant monitoring.

Description

technical field [0001] The invention relates to a PID loop performance evaluation method in the field of industrial automatic control, in particular to a plant-wide monitoring method for loop performance evaluation. Background technique [0002] According to statistics, more than 90% of automatic control loops adopt PID (proportion-proportion, integral-integral, differential-differential) control strategy. With the gradual improvement of industrial automation level, distributed control system [0003] (Distributed Control System, DCS) as the core of the large-scale distributed control system has become a must for industrial production. [0004] In the field of process control, with the help of PID performance evaluation software, it can effectively solve the problem that the operating status of the device is difficult to monitor in real time. However, the existing PID performance evaluation software mainly stays at the workshop level, and does not support the purpose of ce...

AI Technical Summary

Problems solved by technology

However, the existing PID performance evaluation software mainly stays at the workshop level, and does not support the purpose of centralized monitoring of multiple sets of devices scattered in various workshops.

If a factory has a large scale, it has multiple branches and workshops, and each workshop has multiple operation departments, and each operation department may contain one or more PID workstations. Monitoring and management, the evaluation results of each operation department device are scattered in each isolated evaluation system, which will bring great inconvenience to the real-time monitoring and management of upper management personnel
