Automatic control rate and stable rate monitoring system and monitoring method based on tree structure

Abstract

The invention relates to an automatic control rate and stable rate monitoring system and an assessment method based on a tree structure. The system consists of an automatic control rate computation module, a stable rate computation module, a node management module, a team management module, an authority management module and a data interface module which are installed in a web server. A real-timedatabase server is used for storing various original data of devices and providing relevant data interfaces for being called by upper application systems. The web server is responsible for final datarepresentation. Relevant departments and monitored subordinate units can obtain respective data information according to permissions through a local area network in the way of a web browser, wherein the data information includes real-time automatic control rate or history automatic control rate information, real-time stable rate or history stable rate information, team information and the like. The monitoring system can represent the automatic control rate and the stable situation of each team, which include the real-time automatic control rate and stable rate information and the history automatic control rate and stable rate information, and can provide the function of an alarm line. Relevant departments can conduct corresponding assessment to the automatic control rate and the stable rate situation of each team according to the information, so as to supervise and urge each team to conduct corresponding rectification.

Description

technical field [0001] The patent of the present invention relates to a monitoring and assessment system of self-control rate and stability rate applied in industrial control. Background technique [0002] With the increasing maturity of information technology and automation technology, more and more information technology and automation technology are applied in the field of industrial control. At present, the production equipment of most petrochemical enterprises in China adopts distributed control system (DCS). The DCS system can realize functions such as data acquisition, industrial process display, process trend display, configuration information, loop control and historical data storage. These advanced technologies have greatly improved the production efficiency of petrochemical enterprises and brought considerable benefits to the enterprise. However, due to the different purposes of the DCS system itself, it is difficult to implement many advanced monitoring technolog...

AI Technical Summary

Problems solved by technology

[0003] In recent years, monitoring systems with various functions have also appeared in China, which have realized the monitoring function to a certain extent, but there are very few monitoring systems for the self-control rate and stability rate of the device, and the self-control rate and stability rate have not been included. Into the company's assessment system

Moreover, there is no clear definition and explanation for the calculation and statistical methods of the self-control rate and the stability rate, and there are also deficiencies in one way or another in terms of functions.

The main reason is that the list structure in the monitoring system does not adopt a tree structure, which leads to unclear affiliation of the nodes in the list, cumbersome query process and low accuracy, and it is impossible to perform targeted assessment on the device
