[0026] Embodiment

[0027] As Figure 1As shown in the figure, the utility model provides an intelligent early warning control module for coal mine fire safety, which includes a temperature monitoring unit, a gas monitoring unit, a dust monitoring unit, an underground ring network switch, a ground control device and an alarm device. The temperature monitoring unit includes a temperature sensing optical fiber and a mine temperature sensor. The temperature sensing optical fiber includes a distributed temperature sensing optical fiber host and a distributed temperature sensing optical fiber. The distributed temperature sensing optical fiber is laid in the conveyor belt and the goaf. Both the distributed temperature sensing optical fiber host and the mine temperature sensor are connected to the underground ring network switch; the gas monitoring unit includes a toxic gas monitoring sub-unit, a flammable gas monitoring sub-unit and other gas monitoring sub-units. The toxic gas monitoring sub-unit, the flammable gas monitoring sub-unit and other gas monitoring sub-units are respectively connected to the underground ring network switch; the dust monitoring unit includes a mine dust sensor, which is connected to the underground ring network switch; the underground ring network switch is connected to the ground control device through a communication optical cable; the alarm device is connected to the underground ring network switch.

[0028] Further, the alarm device includes an audible and visual alarm.

[0029] The distributed temperature sensing optical fiber host is responsible for receiving signals from the distributed temperature sensing optical fiber, and processing, analyzing and displaying the signals transmitted by the distributed temperature sensing optical fiber. The distributed temperature sensing optical fiber host can monitor the temperature of each point along the optical fiber in real time, intuitively display the temperature data, and provide functions such as temperature anomaly alarm; the audible and visual alarm adopts a dedicated alarm controller, which does not require complex wiring and can be directly installed in each area. The audible and visual alarm is a low-power product with a long service life, saving the maintenance cost of the product.

[0030] In a feasible implementation scheme, the ground control device includes a display, a server and a keyboard. The display and the keyboard are electrically connected to the server. The server includes a map automatic annotation module, and the map automatic annotation module is displayed and interacted through the display.

[0031] The staff can use the keyboard to set and modify the preset ranges of the contents of toxic gases, flammable gases, other gases and dust, as well as the temperature range. The set preset ranges and temperature range can be viewed on the display. At the same time, when the temperature monitoring unit in different areas monitors that the temperature in a certain area is too high, the corresponding local high temperature will be marked on the map and transmitted to the underground ring network switch through the communication optical cable and sent to the alarm device in the corresponding area, such as the audible and visual alarm, to remind the workers in the area that the current location is dangerous and evacuate in the specified direction.

[0033] The intelligent early warning control module for coal mine fire safety can monitor the composition of the air in the mining area in real time through various sensors such as a mine-used carbon monoxide sensor, a mine-used methane sensor, a mine-used ethylene sensor, a mine-used oxygen sensor, and a mine-used carbon dioxide sensor. When the monitored value exceeds or is lower than the preset range, a signal is transmitted to the underground ring network switch, and the underground ring network switch sends the signal to the ground control device. The ground control device pops up a warning message and emits an alarm sound. At the same time, the signal is sent to the alarm device through the communication optical cable and the underground ring network switch to control its activation to notify the workers to evacuate safely and orderly.

[0034] In a feasible implementation, it further includes a fan, a camera, and an electric ball valve.

The staff can check the situation through the camera, confirm the safety of the coal mine, and remotely command the workers to evacuate; start the fan in the corresponding area to exhaust air and accelerate the air circulation in the mine; when the temperature is higher than the set temperature range, the ground control device will control the opening of the electric ball valve to spray the fire extinguishing material to achieve the purpose of extinguishing the fire and cooling down.

[0037] Working principle:

[0038] The staff sets the content ranges of various gases and dusts and the temperature range through the ground control system. When the gas monitoring unit and the dust monitoring unit in the mine detect that the gas or dust content exceeds or is lower than the content range, the corresponding sensor transmits the signal to the ground control device through the underground ring network switch and the communication optical cable. The ground control device will pop up an alarm message and emit an alarm sound, and at the same time control the activation of the audible and visual alarm in the corresponding area to achieve the purpose of notifying the workers to evacuate orderly; at the same time, control the activation of the camera, and the staff can remotely command the workers to evacuate and disperse through the camera; control the activation of the fan in the corresponding area to accelerate the air circulation in the mine and ensure the safety of personnel and property.

[0039] When the temperature monitoring unit in the mine detects abnormal temperature, the signal is transmitted to the ground control device through the underground ring network switch and communication optical cable. The ground control device pops up an alarm message and emits an alarm sound. At the same time, the corresponding area will be automatically marked on the map and displayed on the monitor. The ground control device transmits the start signal through the communication optical cable to the underground ring network switch, and the underground ring network switch transmits the start signal to the cameras and electric ball valves in the corresponding area. After receiving the start signal, the cameras, fans and electric ball valves are turned on. The staff can remotely command the evacuation and withdrawal of workers through the images of the cameras, open the valves of the electric ball valves, and spray fire extinguishing materials to achieve the purpose of cooling down and extinguishing fires.
