Problems solved by technology

[0004] At present, fixed ventilators are usually used in mines to dilute the gas and dust in the roadway. This original total ventilation control mode has low ventilation efficiency, and the working status of the air outlet of the ventilation equipment cannot be dynamically adjusted in real time according to the working environment of the roadway. When the concentration of harmful gases in the mine is abnormal, the ventilation system cannot be well sensed and regulated, and the regulation of ventilation equipment is not in place and not timely, which may cause huge loss of personnel and property at critical moments

Abstract

The invention provides an intelligent regulation and control system and method for mine ventilation equipment based on digital twinning. The system comprises a digital twinning system physical entity, a virtual entity, twinning data and a ventilation equipment intelligent regulation and control system. The digital twinning system physical entity comprises a mine fully-mechanized excavation scene, an excavation working face, ventilation system entity facilities and various sensors; the virtual entity of the digital twinning system refers to a virtual modeling environment of the physical entity, truly maps data information of the physical entity and provides a virtual debugging environment for the ventilation equipment intelligent regulation and control system; the intelligent regulation and control system runs on the virtual entity and acts on the physical entity, and is a key module for realizing real-time interaction between the virtual entity and the physical entity; a ventilation system intelligent regulation and control system is responsible for processing the twinning data, generating a decision scheme through data information and providing intelligent decision information for ventilation system equipment.

Description

technical field [0001] The invention relates to the technical field of mine ventilation equipment control, in particular to an intelligent control system of mine ventilation equipment based on digital twin technology. [0002] technical background [0003] The intelligentization of coal mines is the core technical support for the high-quality development of the coal industry. Coal occupies an important position in my country's energy structure. Safe and efficient mining has always been the goal pursued by the coal industry. The mine ventilation system can supply enough fresh air underground to meet the needs of personnel for oxygen; dilute toxic and harmful gases and dust underground to ensure safe production; adjust the underground climate to create a good working environment. In the process of coal mining, a large amount of harmful factors such as gas and dust will accumulate in the fully mechanized excavation face, which seriously affects the life and health of miners. Ho...
