[0016] The present invention is described in detail below in conjunction with embodiments, but the present invention is not limited to these embodiments.

[0017] like Figure 1 and Figure 2As shown, the present invention provides a high-altitude coal mine safety fire prevention and extinguishing system, including an information collection terminal 1, an information dispatching terminal 2 and an early warning fire extinguishing terminal 3. The information collection terminal 1 is arranged in each operating area of ​​the coal mine, and is used to collect fire information in each operating area; the information dispatching terminal 2 is connected to the information collection terminal 1, and the information dispatching terminal 2 has a model building module 23. The model building module 23 generates a fire monitoring model by simulating training according to the on-site operating conditions of each operating area, and couples the fire information of any operating area collected by the information collection terminal 1 to the fire monitoring model for real-time display; the early warning fire extinguishing terminal 3 has an early warning setting module 31, a judgment module 32, a control module 33, a fire extinguishing module 35 and an alarm module 34 installed in each operating area, wherein the early warning setting module 31 is used to set the fire monitoring threshold in each operating area; the judgment module 32 is connected to the early warning setting module 31 and the information collection terminal 1, and is used to determine whether the fire information collected in each operating area exceeds the fire monitoring threshold; if the fire information collected in each operating area exceeds the fire monitoring threshold, the early warning fire extinguishing terminal 3 has a warning setting module 31, a judgment module 32, a control module 33, a fire extinguishing module 35 and an alarm module 34 installed in each operating area. If the fire information collected in the operating area does not exceed the fire monitoring threshold, the fire warning level of the operating area is safe; if the fire information collected in the operating area exceeds the fire monitoring threshold, the fire warning level of the operating area is unsafe; the control module 33 is connected to the determination module 32, and a first fire warning instruction is generated when the fire warning level of the operating area is safe, and a second fire warning instruction and a fire extinguishing instruction are generated when the fire warning level of the operating area is unsafe; the alarm module 34 is connected to the control module 33, and is used to receive the first fire warning instruction or the second fire warning instruction issued by the control module 33, and control the alarm in the corresponding operating area to display the warning mark and sound the alarm according to the first fire warning instruction or the second fire warning instruction, so as to guide the operating personnel in all operating areas of the coal mine to evacuate in an orderly manner according to the warning mark and the alarm frequency; the fire extinguishing module 35 is connected to the control module 33, and is used to receive the fire extinguishing instruction issued by the control module 33, and control the fire extinguishing unit to perform the fire extinguishing action on the corresponding operating area according to the fire extinguishing instruction.

[0018] In the above, by independently monitoring multiple different operating areas of the coal mine, the possibility of fire in the coal mine caused by changes in the geographical environment caused by altitude and different working conditions in the operating areas can be fully considered, and the corresponding fire monitoring threshold is set according to the actual working conditions of each operating area, so as to improve the accuracy of the collection of fire information in the operating area, and the collected fire information is uploaded to the information dispatching terminal 2 and the early warning fire extinguishing terminal 3 in real time. The early warning fire extinguishing terminal 3 controls the fire extinguishing unit to timely extinguish the operating area where the fire occurs, and controls the alarm in the corresponding operating area to display the early warning mark and sound the alarm, so as to guide the operators in all operating areas of the coal mine to take timely measures according to the actual working conditions of the coal mine. Evacuate in an orderly manner according to the early warning signs and alarm frequencies to avoid misjudgment and erroneous actions by on-site workers, and prevent chaos at the construction site from causing safety accidents (for example, workers in the work area where no fire has occurred evacuate quickly upon hearing the evacuation alarm from other work areas, causing congestion in the safe escape passage, thereby preventing workers who need to evacuate from evacuating in time and causing safety accidents); at the same time, the fire information is fed back to the information dispatch terminal 2, so that the on-duty personnel can promptly understand the specific location of the work area where the fire has occurred, so as to guide the workers in the work area to evacuate to a safe area, avoid secondary safety accidents caused by the fire, and reduce the damage caused by the fire to the workers.

[0019] In the above, the alarm has at least two warning signs, and the two warning signs use indicator lights of different colors. Among them, the first fire warning instruction is: the warning sign of the alarm is displayed in green, and the alarm alarm frequency of the alarm tends to diverge. The second fire warning instruction is: the warning sign of the alarm is displayed in red, and the alarm alarm frequency of the alarm tends to be concentrated. When a fire occurs, it is convenient for the operators in each operating area to determine whether to evacuate according to the corresponding warning signs and alarm alarm frequencies. At the same time, the operators can judge the spread speed of the fire according to the change amplitude of the alarm alarm frequency. Specifically, there are multiple fire warning levels, and the alarm alarm frequencies of multiple fire warning levels tend to be concentrated as the fire warning level gradually increases. For example, the higher the fire warning level, the denser the alarm alarm frequency.

[0020] In the above, the information collection terminal 1 includes a data processing module 12 and a data collection module 11 installed in each operation area, and the data collection module 11 is used to detect the fire information in the operation area; the data processing module 12 is connected to the data collection module 11 in each operation area, and is used to synchronously receive the fire information collected by the data collection module 11 in each operation area, and calculate the fire information deviation value of two adjacent operation areas and judge whether the change amplitude of the fire information deviation value tends to increase or decrease, so as to obtain the fire spread direction in the two adjacent operation areas and couple it to the fire information and upload it to the fire monitoring model, which is used to feedback the fire spread path in real time in the fire monitoring model, so that the on-duty personnel can plan a reasonable evacuation route according to the fire spread path, guide the on-site workers to evacuate according to the evacuation route, thereby evacuating the concentration of the workers, improving the evacuation speed and reducing the occurrence of hypoxia or squeezing injuries caused by crowding of the workers, wherein; if the change amplitude of the fire information deviation value tends to increase, it means that the fire spreads from the previous operation area to the next operation area; if the change amplitude of the fire information deviation value tends to decrease, it means that the fire spreads from the next operation area to the previous operation area.

[0021] In the above-mentioned embodiment, the information dispatch terminal 2 also has a collaborative dispatch module 21, which is connected to the alarm module 34, so that the on-duty personnel can adjust the warning signs of the alarms in all working areas along the direction of fire spread to red in turn through the collaborative dispatch module 21 according to the direction of fire spread in the working area where the fire occurs, so as to realize the orderly evacuation of the working personnel.

[0022] In the above, the fire extinguishing unit includes a fire extinguishing pipeline 4, a fire extinguishing agent input device 5, a stop valve 6 and an injection valve 7 installed in each working area, and two adjacent fire extinguishing pipelines 4 are connected end to end; the discharge port of the fire extinguishing agent input device 5 is connected to the feed port of one of the fire extinguishing pipelines 4, which is used to pump the fire extinguishing agent into the fire extinguishing pipeline 4; the stop valve 6 is installed at the feed end of each fire extinguishing pipeline 4, which is used to control the connection and disconnection between the fire extinguishing pipeline 4 and the fire extinguishing agent input device 5; the injection valve 7 is installed at the fire extinguishing preset position of the fire extinguishing pipeline 4 facing the working area, which is used to inject the fire extinguishing agent from the fire extinguishing pipeline 4 to the fire extinguishing preset position of the working area for fire extinguishing. Specifically, when a fire is detected in one of the working areas, the fire extinguishing module 35 receives a fire extinguishing instruction to control the injection valve 7 and the stop valve 6 in the corresponding working area and all the stop valves 6 on the connection section with the fire extinguishing agent input device 5 to open, and at the same time controls the fire extinguishing agent input device 5 to pump the fire extinguishing agent into the fire extinguishing pipeline 4, and spray it from the injection valve 7 to the preset fire extinguishing position in the working area to extinguish the fire in time, thereby reducing the economic losses and safety hazards caused by the fire; and, by shutting off the subsequent fire extinguishing pipeline 4 through the stop valve 6, it can ensure that the fire extinguishing agent in a single fire extinguishing pipeline 4 quickly reaches the injection pressure, reducing the start-up delay of the fire extinguishing unit, and by reducing the number of fire extinguishing agent input devices 5, it can reduce the maintenance intensity, thereby avoiding missed detection and ensuring the stable operation of the fire extinguishing agent input device 5 when a fire occurs.

[0023] Specifically, the data acquisition module 11 includes a temperature sensor, a smoke sensor and an oxygen sensor; wherein the temperature sensor is used to collect the temperature value in the working area; the smoke sensor is used to detect whether there is smoke and the concentration of smoke in the working area, and the oxygen sensor is used to collect the oxygen content of the air in the working area; the temperature value and whether there is smoke and the concentration of smoke are used to judge whether a fire has occurred in the working area. In the above, the information dispatching terminal 2 also has an analysis module 22, which is connected to the data acquisition module 11. The analysis module 22 is used to obtain the temperature value collected by the temperature sensor in each working area and the oxygen content of the air collected by the oxygen sensor, and generate a fire risk level assessment table according to the temperature value and the oxygen content of the air in each working area, so as to facilitate the assessment of the probability of fire in each working area according to the fire risk level assessment table, and at the same time, improve the safety awareness of the working area with a high probability of fire, and reduce the probability of accidents.

Although the present invention is disclosed as above in the form of a preferred embodiment, it is not intended to limit the present invention.
