Description

Technical Field

[0001] This application relates to the technical field of equipment control, and particularly to a control method, device, and readable storage medium for a gas pressurization system. Background Art

[0002] Gas pressurization facilities mainly provide stable pressure supply for remote users in the production of metallurgical coking enterprises, and play an important and positive role in the enterprise's work safety activities. Due to the structural characteristics of the pressurization facilities themselves, they need to be regularly maintained and repaired cyclically. Therefore, generally, multiple sets of pressurization facilities are configured to meet production needs, including those for production use and those for standby maintenance. When maintenance is required, the inlets and outlets of the pressurization facilities should be isolated, and purged and replaced, and only after passing the detection can maintenance be carried out. In recent years, due to ineffective isolation of the inlets and outlets of the pressurization facilities during maintenance, incomplete purging and replacement, etc., gas leakage has occurred, resulting in poisoning accidents of personnel.
