Description

Technical Field

[0001] The present invention relates to the technical field of mine safety monitoring, and in particular to a novel underground information collection and closure system based on RFID positioning. Background Art

[0002] In the daily operation of the mine, it is crucial to ensure the safety of underground personnel and equipment. However, due to the complexity of the underground environment and the high risk of the operation, traditional monitoring and safety systems often fail to meet the requirements of real-time and accuracy. Existing technologies mainly rely on manual inspections and fixed-position sensors for monitoring, but this approach has many shortcomings. First, manual inspections cannot achieve full coverage and real-time monitoring, which can easily lead to hidden dangers being overlooked. In addition, the coverage of fixed sensors is limited, and the movement of underground equipment and personnel cannot be tracked in real time, resulting in information lags and difficulty in timely detection and handling of emergencies.

[0003] In traditional systems, signal collection and locking operations usually rely on manual operation or simple automatic control based on preset conditions. This control method is not flexible enough and difficult to adapt to the complex and dynamically changing conditions in the underground environment. When an emergency occurs underground, the existing system often does not respond quickly enough and cannot effectively prevent the occurrence or spread of danger, further increasing the safety risks of operators and equipment.

[0004] In addition, the traditional monitoring system has bottlenecks in real-time data transmission and processing. The underground environment is complex and communication signals are easily interfered with, making it difficult to ensure the stability and reliability of data transmission. At the same time, due to the low integration of the traditional system, the data sharing and linkage between modules are poor, and effective global monitoring and unified control cannot be formed, which further limits the application effect of the system in complex environments.
