Problems solved by technology

[0009] The present invention is aimed at the problems existing in the prior art, and provides an automatic control system for gas cabinets. This technical solution mainly solves the problem of excessive manual intervention in switching gas cabinet inlets and outlets existing in most iron and steel enterprises at present before, after and during the maintenance of the main production line. The valves lead to the deterioration of the stability of the gas system pipeline network, and realize the automatic regulation of the target counter position under the online operation state of the gas cabinet, ensuring the stability of the gas system; the automatic regulation of the gas cabinet is based on the gas balance prediction module, and the data is refreshed in real time, further Improve the accuracy of gas cabinet control

Embodiment 1

[0028] Example 1: see figure 1 , a gas cabinet automatic regulation system, the gas cabinet automatic regulation system is composed of a gas prediction module, a gas balance module, a gas cabinet regulation module, and an EMS power real-time database, a relational database and a client, and the main function of the gas prediction module is from The EMS database captures data such as gas generation, user gas consumption, steel rolling unit rolling plan information, steelmaking unit smelting plan, main line maintenance plan, gas cabinet counters and other data stored in the relational database. The model background program reads and stores data in the relational database. The configuration information of each prediction item in the database is used to train and predict the model, and the gas prediction results in the future T time are stored in the relational database, and the trend of each medium is fed back to the client; the main function of the gas balance module is to predic...

Embodiment 2

[0038] Example 2: see figure 1 , the automatic regulation control method of gas cabinet automatic regulation system, described method is as follows:

[0039] The gas prediction module collects data such as gas generation, user gas consumption, steel rolling unit rolling plan information, steelmaking unit smelting plan, main line maintenance plan, gas cabinet counters and other data from the EMS database and stores them in the relational database. The model background program reads The configuration information about each prediction item stored in the relational database is used for model training and prediction, and the gas prediction results in the future T time are formed and stored in the relational database, and the trend of each medium is fed back to the client;

[0040] The gas balance module mainly calculates the gas adjustment amount Q based on the results of the gas prediction module, the manually given target counter position H and time T, and the gas adjustment amou...

Abstract

The invention relates to an automatic regulation and control system for a gas holder, the automatic regulation and control system of the gas holder of an iron and steel enterprise mainly comprises a gas system prediction module, a gas balance module and a gas holder regulation and control module, wherein the three modules are correlated to realize automatic regulation and control of the gas holder, and the whole gas system is promoted to stably operate during main line maintenance and normal production. The system mainly solves the problem of poor stability of a gas system pipe network caused by excessive manual intervention of inlet and outlet valves of the gas holder in most metallurgical enterprises at present, realizes automatic control of the target holder position of the gas holder in the operation state of hanging the network, and ensures the stability of the gas system. The combination of the gas cabinet position regulation and control and the gas consumption prediction model improves the accuracy and timeliness of the gas cabinet position regulation and control.

Description

technical field [0001] The invention relates to a control system, in particular to an automatic control system for a gas cabinet, and belongs to the technical field of automatic control systems for gas cabinets. Background technique [0002] In recent years, the development and research of the gas forecast balance model has been continuously improved, and the accuracy of the gas consumption forecast has also been continuously improved, which plays an important role in improving the flexibility of the enterprise's comprehensive gas balance and reducing gas emissions. With the improvement of the automation level of enterprises, the gas forecast balance model is more and more widely used, such as the prediction of converter gas generation based on steel grade information, the gas demand prediction of steel rolling process based on rolling plan, the blast furnace gas generation prediction, The accuracy of the prediction of gas cabinet counters has been continuously improved, and...
