[0002] A mine is a general term for the shafts, chambers, equipment, ground buildings and structures that form an underground coal mine production system. Sometimes, the inclined shafts, vertical shafts, and horizontal shafts in the underground development of mines are also called mines. The size of the mine field, the production capacity and service life of each mine are one of the key issues that must be solved in the mine design.

[0003] Advance detection of tunnels is to detect ahead of the tunnel excavation working face by drilling, geophysical exploration or geochemical exploration. The main task is to find out whether there are abnormal water bodies or water-conducting channels, abnormal structures, and gas-rich areas in front of the tunnel excavation working face, so as to provide geological data for safe tunnel excavation. For the selection of geophysical exploration technology, the geologists first determine whether to carry out geophysical exploration construction based on the actual situation on site. After the construction is determined, the geophysical exploration personnel carry geophysical exploration instruments to the target area for detection, and then return to the well for analysis, and finally issue a geophysical exploration report to guide production. The overall process safety factor is low, and the collected data cannot be transmitted to the ground in real time, and the ground personnel receive information at a poor speed. Summary of the invention

[0004] The purpose of the present invention is to solve the problems in the prior art that the overall process safety factor is low, the collected data cannot be transmitted to the ground in real time, and the information receiving speed of ground personnel is poor, and a remote control system for geophysical exploration instruments based on mine Internet of Things technology is proposed.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

If the input content does not match the stored content, the administrator permission cannot be granted. If the input content corresponds to the stored content, the permission is granted;

[0008] A geophysical prospecting component, wherein the geophysical prospecting component includes an information acquisition unit, which is connected to a signal transmission module; the information acquisition unit completes the collection of geological information, and converts the geological information into a signal recognizable by a field control unit through the signal transmission module, and sends the signal to the field control unit, and the field control unit sends the information to an external control unit;

[0009] The geophysical prospecting component is fixed on a support frame through a telescopic unit, and a lighting unit and a 360 camera unit are fixed on the support frame; the support frame is fixed on a tunnel excavation equipment or a crawler walking vehicle; a field control unit is fixed on the support frame, and the output end of the geophysical prospecting component, the output end of the 360 ​​camera unit and the control end of the telescopic unit are connected to the field control unit, and the field control unit is connected to a UWB positioning unit and a second signal communication unit; the first signal communication unit and the second signal communication unit are communicatively connected; the first signal communication unit and the second signal communication unit establish a data transmission connection between the geophysical prospecting component and the control system, and when the signal transmission module transmits the collected information to the control system, the control system can receive it in time, and the control system can also send control instructions to the geophysical prospecting component.

[0010] The external control unit communicates with the on-site control unit, and the external control unit obtains geological information in real time and enters the geological information in real time; then the geological information is sent to the safety analysis module. After the safety analysis module obtains the geological information, it compares the threshold of the geological information. When one or more geological information exceeds the set safety value range, the external control unit issues a geological unqualified pop-up window, and simultaneously displays the exceeded value, and marks the unqualified location on the display screen.

[0012] Furthermore, the UWB positioning unit obtains the real-time geographic location of the support frame carrying the geophysical exploration component inside the mine. When the geophysical exploration component conducts geophysical exploration, the UWB positioning unit marks the currently acquired positioning points on the map on the display screen. At the same time, since the coordinate system of each geophysical exploration component on the support frame is fixed, the detection image is acquired through the 360 ​​camera unit, and the position points and detection data of each geophysical exploration component are fed back to the detection image according to the coordinate system.
