[System Features]

A large number of coal mine water inrush accidents have shown that the vast majority of water inrush (seepage) accidents are induced by mining engineering activities. The fine exploration technology for concealed water sources and water channels, as well as the short-term critical prediction technology for water inrush, are bottleneck technologies that restrict the effectiveness of coal mine water prevention and control. At present, there is a serious lack of automatic monitoring technology and equipment, which cannot provide real-time and reliable monitoring and early warning of mine water during the mining process. Therefore, researching real-time monitoring and early warning technology for major mine water inrush disasters is an important issue to improve the effectiveness of water prevention and control work in coal mines and ensure the safety of coal mining.

[System Function]

◆ Water inflow collection substation function:

(1) Water temperature, flow rate, and water pressure data collection;

(2) Data temporary storage;

(3) Data display;

(4) Transmit data to the data communication substation through the CAN bus.

◆ Communication substation function:

(1) Convert the CAN bus data sent by the collection substation into fiber optic signals;

(2) Upload the signal to the ground communication control station.
