[0031] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0032] The present invention provides intelligent underground mine monitoring equipment.

[0033] like Figure 1 to Figure 2 The shown type of intelligent underground monitoring equipment for a mine includes a central control center (not shown in the figure) and at least one monitoring station 1, wherein the central control center is electrically connected to each monitoring station 1; the monitoring station 1 is provided with a camera 11, a signal transmitter (not shown in the figure) and a controller, wherein the controller is electrically connected to the central control center, the camera 11 and the signal transmitter, respectively, and the camera 11 is used to obtain real-time images within a preset range and send them to the controller; the controller is used to enable the controller to determine a status level within a preset range based on the real-time image when the electrical connection between the central control center and the controller is disconnected; the controller is used to control the signal transmitter according to the status level, so that the signal transmitter sends a distress message to the outside world.

[0034] The monitoring stations 1 are evenly distributed above and below the mine. When the mine collapses unexpectedly and causes the central control center and the monitoring stations 1 to be disconnected, the monitoring stations 1 determine the status level of a preset range based on the real-time image obtained by the camera 11, and send a distress message to the external building based on the status level, providing detailed rescue coordinates for external rescue personnel to speed up the rescue.

[0035] Specifically, the signal transmitter can be selected according to the actual situation in the mine.

[0036] The controller is used to determine whether there are people to be rescued in the current preset range based on real-time images when the electrical connection between the central control center and the controller is disconnected. When there are people to be rescued in the preset range, the signal transmitter sends a distress message to the outside world; when there are no people to be rescued in the preset range, the signal transmitter enters a silent state. Sending distress messages based on the people to be rescued allows external rescuers to quickly confirm underground information and conduct rescue, providing effective information support to the outside world.

[0037] Specifically, the rescue information includes first information, second information and third information.

[0038] Specifically, when there are people to be rescued within the preset range, the controller determines the status of the number of people and the number of wounded according to the real-time image. When the number of people is greater than zero and less than or equal to three, or when the number of wounded is zero, the signal transmitter sends the first information to the outside world; when the number of people is greater than or equal to three and less than ten, or when the number of wounded is greater than zero and less than or equal to three, the signal transmitter sends the second information to the outside world; when the number of people is greater than ten, or the number of wounded is greater than or equal to three, the signal transmitter sends the third information to the outside world. Different information is sent according to the number of people to be rescued and the number of wounded trapped underground, so that the outside rescuers can quickly and accurately judge the actual situation of being trapped.

[0039] Specifically, the number of personnel includes the number of wounded, and the number of personnel is greater than or equal to the number of wounded.

[0040] Specifically, the controller is also used to determine cracks and abnormal protrusions based on real-time images, then determine crack sizes based on the cracks, and determine dangerous areas and safe areas based on the crack sizes and abnormal protrusions; the controller is also used to control audio equipment to send voice prompts to rescue personnel based on the safe area and real-time images, so that the rescue personnel can enter the safe area.

[0041] Specifically, the controller is also used to determine the danger level within a preset range based on the crack size and abnormal protrusions. When the preset size is greater than the first preset size or the abnormal protrusion is greater than the second preset size, or the sum of the preset size number and the abnormal protrusion number is greater than the preset number, the control signal transmitter sends a distress message and a warning message at the same time.

[0042] Specifically, the first preset size is the length of the crack; the abnormal protrusion is a protruding stone or a broken steel bar caused by collapse, and the second preset size is the protruding length of the stone or steel bar.

[0043] Determine whether there is a possibility of a secondary accident within the preset range. When there is a possibility of a secondary accident, the signal transmitter sends rescue information and accident information to the outside world.

The setting of multiple storage mechanisms 4 can provide food, water, oxygen and medicine to persons to be rescued in an emergency, effectively improving the survival rate of persons to be rescued. And providing survival supplies regularly and quantitatively according to the number information of persons to be rescued can effectively extend the rescue time and further improve the survival rate of persons to be rescued.

[0051] Specifically, the monitoring station 1 is also provided with an audio device 16, and the controller is electrically connected to the audio device 16.
