The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments.

[0044] Please refer to Figure 1 , which is a schematic flowchart of a method for determining an escape plan based on environmental monitoring in a coal mine in an embodiment of this application. The method includes:

[0045] S110. Obtain the first air environment information in the first detection area on the periphery of the target staff, where the first detection area is an area with a distance less than or equal to the first distance from the target staff;

[0046] Exemplarily, the first air environment information in the area with a distance less than or equal to the first distance from the target staff in the coal mine roadway is obtained in real time. For example, the first distance can be the straight-line distance between the target staff and the safe area. For example, the first distance can be 500 m, and the first air environment information in the area within 500 meters around the target staff is obtained. The first air environment information may include the concentration of harmful gases such as hydrocarbons such as CO, H2S, and CH4.

[0047] S120. Obtain the first distribution information of harmful gases according to the first air environment information;

[0048] Exemplarily, the first distribution information of harmful gases is obtained according to the first air environment information. The first distribution information of harmful gases refers to the concentration distribution of harmful gases in the first area. The first distribution information of harmful gases can be the distribution information of a single type of harmful gas, or the comprehensive concentration distribution information of multiple harmful gases calculated based on a specific algorithm.

[0049] S130. Determine the first escape route according to the above-mentioned first distribution information of harmful gases, where the first escape route is the escape route corresponding to the harmful gas concentration lower than the preset safety concentration.

[0050] Exemplarily, the first escape route for the target staff to move to the safe area is determined according to the above-mentioned first distribution information of harmful gases. The first escape route is the shortest escape route corresponding to the harmful gas concentration lower than the preset safety concentration. The preset safety concentration is the maximum concentration at which harmful gases to the human body are not sufficient to endanger human health, that is, the obtained first escape route is the shortest escape route for evacuation when the staff breathes normally while ensuring the health of the staff.

[0051] S140. Guide the target staff to move to the target safe area based on the above-mentioned first escape route.

[0052] Exemplarily, guide the target staff to move to the target safe area based on the first escape route so that the target staff can get out of danger. The guiding method can be voice broadcast of the route or light signal guidance.

[0053] In summary, the escape plan based on environmental monitoring in coal mines proposed in this application monitors the first air environment information in the coal mine roadway, obtains the first distribution information of harmful gases based on the first air environment information, determines the first escape route for the target staff to move to the safe area where they can breathe normally and the route is the shortest according to the first distribution information of harmful gases, and guides the target staff to move to the safe area according to the first escape route. This method provides a fast and safe escape plan when harmful gas leakage occurs in coal mines, ensuring the life and health safety of underground workers.

[0054] In some examples, the obtaining of the first air environment information in the first detection area on the periphery of the target staff includes:

[0055] Obtain the first air environment information in the first detection area on the periphery of the target staff through the environmental monitoring device installed in the coal mine roadway.

[0056] Exemplarily, the first air environment information in the first detection area of the weekly test of the target staff can be measured by an environment detection device installed in the coal mine roadway. The environment detection devices can be arranged at fixed distance intervals underground. Through the data measured by multiple environment detection devices, the air environment information of the entire underground can be calculated and processed. When it is detected that the harmful gas in the environment exceeds the standard, the first air environment information in the first detection area of the weekly test of the target staff is immediately generated to determine the escape route of the target staff.

[0057] In summary, by installing environment detection devices in the roadway of the mine, the air quality underground can be monitored in real time, so that the phenomenon of dangerous gas exceeding the standard can be detected in time. When the dangerous gas exceeds the standard, the first air environment information in the first detection area of the weekly test of the target staff is quickly generated, and the escape route of the target staff is quickly determined based on this to ensure the timely evacuation of the staff.

[0058] In some examples, the above method further includes:

[0059] When the above-mentioned target staff carries an oxygen tank, obtain the remaining oxygen capacity information of the oxygen tank corresponding to the above-mentioned target staff;

[0060] Determine a second escape route based on the above-mentioned first distribution information of harmful gases and the above-mentioned remaining oxygen capacity information of the oxygen tank;

[0061] Guide the above-mentioned target staff to move to the above-mentioned target safe area based on the above-mentioned second escape route.

[0062] Exemplarily, if the target staff carries an oxygen supply device, they can safely pass through the area where the harmful gas concentration exceeds the standard by inhaling oxygen. Among them, the oxygen supply device can be an oxygen tank storing oxygen. By obtaining the remaining capacity information of the oxygen tank, the time that the remaining oxygen capacity can be used by the target staff can be determined. A second escape route is determined according to the remaining capacity and the first distribution information of harmful gases. The second route is the escape route corresponding to the situation where oxygen can be inhaled throughout the escape process or there is a section where the harmful gas exceeds the standard. The target staff is guided to move to the target safe area according to the second escape route.

[0063] In summary, the method provided in the embodiment of the present application, when the target staff carries an oxygen supply device with them, generates a second escape route by obtaining the remaining oxygen capacity in the oxygen supply device and the first distribution information of harmful gases, which can guide the staff to inhale the oxygen in the oxygen tank to escape when the harmful gas concentration exceeds the standard, thereby improving the escape success rate of the staff in dangerous situations.

[0064] In some examples, the above method further includes:

[0065] Obtain the current location of the target staff member;

[0066] Determine the shortest movement duration corresponding to the shortest escape route between the above current location and the above target safe area;

[0067] Obtain the available oxygen inhalation duration corresponding to the above target staff member according to the remaining oxygen capacity of the above oxygen cylinder;

[0068] When the difference between the above available oxygen inhalation duration and the above shortest movement duration is greater than or equal to a preset safety duration, guide the above target staff member to move to the above target safe area based on the above shortest escape route.

[0069] Exemplarily, obtain the current location of the target staff member, calculate the movement duration corresponding to the shortest movement path from the current location to the target safe area, calculate the duration for which the target staff member can inhale oxygen through the remaining oxygen capacity of the oxygen cylinder. If the available oxygen inhalation duration is greater than the shortest movement duration, it is considered that the target staff member can inhale oxygen throughout the process and move to the target safe area along the shortest escape route, so as to evacuate at the fastest speed. It can be understood that, in order to fully ensure the safety of the target staff member during the escape process, a reasonable preset safety duration should be set when calculating whether the oxygen inhalation duration can allow the target staff member to move to the target safe area, that is, when the difference between the available oxygen inhalation duration and the above shortest movement duration is greater than or equal to the preset safety duration, the target staff member is guided to move to the above target safe area based on the shortest escape route.

[0070] In summary, the method provided in the embodiment of the present application, by calculating the available oxygen inhalation duration of the remaining oxygen capacity of the oxygen cylinder and the shortest movement duration for the target staff member to move to the target safe area, when the difference between the available oxygen inhalation duration and the above shortest movement duration is greater than or equal to the preset safety duration, guides the target staff member to move to the above target safe area based on the shortest escape route, and can enable the target staff member to evacuate to the target safe area at the fastest speed when there is sufficient oxygen.

[0071] In some examples, the above method further includes:

[0072] When the difference between the above available oxygen inhalation duration and the above shortest movement duration is less than the above preset safety duration, determine a third escape route and a preset oxygen inhalation strategy based on the above available oxygen inhalation duration and the first distribution information of harmful gases, where the above third escape route is the relatively shortest route when the above oxygen inhalation duration can maintain the normal use of the above target staff member, and the above preset oxygen inhalation strategy is a switching plan for inhaling oxygen or not inhaling oxygen on different sections of the above third escape route determined according to the above first distribution information of harmful gases;

[0073] Based on the above third escape route and the preset oxygen inhalation strategy, guide the above-mentioned target staff to move to the above-mentioned target safe area.

[0074] Exemplarily, when the difference between the available oxygen inhalation duration and the shortest movement duration is less than the preset safety duration, it means that even if the target staff escapes along the shortest escape route relying entirely on oxygen inhalation, the oxygen is not enough to maintain their breathing. At this time, determine the third escape route and the preset oxygen inhalation strategy according to the first distribution information of harmful gases. The preset oxygen inhalation strategy includes the switching scheme of oxygen inhalation and non-oxygen inhalation. Specifically, for example: the current position of the target staff is point A, and the target safe area is the area where point D is located. The routes from point A to point D are as follows: Route 1: A - B - C - D (the shortest distance), Route 2: A - B1 - C1 - D (the second shortest distance), Route 3: A - B2 - C2 - D (the longest distance). According to the first distribution information, it is determined that the harmful gas concentrations in sections A - B, B - C, C - D, A - B1, and A - B2 exceed the standard, and the harmful gas concentrations in the remaining sections of the route are at normal levels. After calculation, for Route 1: A - B - C - D, the movement duration of the shortest movement route is 10 minutes, but the available oxygen inhalation duration is only 8 minutes. The plan of full oxygen inhalation and escaping along the shortest route cannot meet the oxygen inhalation duration of the staff. The movement duration of section A - B1 is obtained as 3 minutes, and for Route 2: A - B1 - C1 - D, the movement duration of the second longest route is 12 minutes; the movement duration of section A - B2 is obtained as 5 minutes, and for Route 3: A - B2 - C2 - D, the movement duration of the second longest route is 15 minutes. In this case, Route 2 is the most reasonable escape route. That is, on the premise that the oxygen can maintain the normal breathing of the target staff, the movement route is the shortest, which can not only ensure the safety of the escape process but also ensure a relatively fast evacuation. The corresponding oxygen inhalation strategy for Route 2 is to inhale oxygen in section A - B1 and not inhale oxygen in section B1 - C1 - D.

[0075] In summary, for the method proposed in the embodiment of the present application, when the difference between the available oxygen inhalation duration and the shortest movement duration is less than the preset safety duration, calculating the third escape route through the first distribution information of harmful gases and the available oxygen inhalation duration can ensure that, on the premise that the oxygen can maintain the normal breathing of the target staff, the movement route is the shortest, which can not only ensure the safety of the escape process but also ensure a relatively fast evacuation.

[0076] In some examples, the above method further includes:

[0077] Obtain the second distribution information of harmful gases in the second detection area around the above-mentioned target staff, where the second detection area is the area where the distance from the above-mentioned target staff is less than or equal to the second distance, and the second distance is less than the first distance;

[0078] When the concentration difference of the harmful gas corresponding to the second distribution information of the harmful gas and the first distribution information of the harmful gas is greater than the acceptable concentration difference, the above-mentioned preset oxygen inhalation strategy is adjusted.

[0079] Exemplarily, in order to prevent the rapid diffusion or transfer of harmful gases in the coal mine, during the escape process of the target staff, the concentration of harmful gases in a closer area around them should be monitored in real time, that is, the second distribution information of the harmful gases is obtained. If the concentration difference of the harmful gas corresponding to the second distribution information of the harmful gas and the first distribution information of the harmful gas is greater than the acceptable concentration difference, that is, the concentration of the harmful gas has changed greatly. At this time, the preset oxygen inhalation strategy can no longer meet the requirements of the current environment, that is, the preset oxygen inhalation strategy should be adjusted, that is: if the preset strategy is oxygen inhalation, it is adjusted to non-oxygen inhalation; if the preset strategy is non-oxygen inhalation, it is adjusted to oxygen inhalation. By obtaining the second distribution information of the harmful gas, the impact of the changing gas concentration on the escape of the target staff can be effectively prevented, the safety of the escape personnel can be fully ensured when the concentration of the harmful gas increases, and at the same time, when the concentration of the harmful gas decreases, the consumption of oxygen resources can be saved, leaving a greater safety margin for the escape process.

[0080] In summary, the method provided by the embodiment of the present application can fully ensure the safety of the escape personnel when the concentration of the harmful gas increases by obtaining the second distribution information of the harmful gas within the second distance closer to the target personnel during the escape process of the target personnel to adjust the oxygen inhalation strategy, and at the same time, when the concentration of the harmful gas decreases, the consumption of oxygen resources can be saved, fully ensuring the safety of the escape process.

[0081] In some examples, obtaining the second distribution information of the harmful gas in the second detection area around the above-mentioned target staff includes:

[0082] Obtaining the second distribution information of the harmful gas in the second detection area around the above-mentioned target staff through the portable harmful gas detection device carried by the above-mentioned target staff.

[0083] Exemplarily, detecting the second distribution information of the harmful gas in the second detection area around the target staff can be obtained through the harmful gas detection device carried by the target staff. The harmful gas detection device can be installed on the safety helmet of the target staff so that the mouth and nose of the target staff are at the same height, which is better for judging the impact of the harmful gas on the respiratory system.

[0084] Please refer to Figure 3 , the present invention also proposes an escape plan determination device based on environmental monitoring in a coal mine, including:
