Description

Technical Field

[0001] The present application relates to the technical field of mine fire prevention, and in particular to a control method, system, terminal and medium for a mine fire door. Background Art

[0002] A mine is a general term for the shafts, chambers, equipment, ground buildings and structures that form an underground coal mine production system. Safety accidents are prone to occur in mines due to improper underground operations, poor workplace and ventilation, and accumulation of gas and coal dust. When ignited by open flames from illegal operations, gas explosions and mine fires will occur. Under the interaction of high temperature of the fire, high pressure of the explosion and secondary fire sources, the fire is very easy to spread, aggravating the hazards of the accident. People affected by the fire and explosion accidents will inevitably suffer burns, explosion injuries, or even death. At this time, fire doors are needed to protect the safety of workers. Fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and thermal insulation within a certain period of time.

[0003] In the related art, when a fire occurs in a mine, the fire doors are usually closed directly to isolate the flames; since intelligent monitoring and management cannot be implemented according to the on-site environment, it is becoming less and less suitable for safe production in coal mines. Summary of the invention

[0004] In order to facilitate intelligent monitoring and management of fire doors according to the on-site environment, the present application provides a control method, system, terminal and medium for mine fire doors.

[0005] In a first aspect, the present application provides a method for controlling a mine fire door, which adopts the following technical solution:

[0006] A method for regulating a mine fire door, comprising:

[0007] Receive sensor data sent by sensors around each fire door;

[0008] determining whether a fire occurs inside the mine based on the plurality of sets of sensor data;

[0009] If yes, determine the target fire door based on the fire spread area;

[0010] Obtaining personnel location information of personnel around the target fire door;

[0011] Based on the personnel location information, determine whether the personnel are on the fire spread path and between the target fire door and the fire spread boundary;

[0012] If yes, then control the closing degree of the target fire door according to the spreading speed of the fire;

[0013] If not, the closing degree of the target fire door is controlled according to the fire intensity.

[0014] By adopting the above technical solution, the fire situation is judged by receiving data from sensors around the fire door, and then the location information of the staff is obtained, which can accurately determine whether the personnel are in a dangerous fire spread path and between the target fire door and the fire spread boundary. In the case of being in such a dangerous position, the closing degree of the target fire door is controlled according to the fire spread speed. While ensuring the prevention of the spread of the fire, it is possible to leave enough time for the relevant personnel to evacuate safely, avoiding people being trapped in the dangerous area due to the target fire door closing too quickly, effectively improving the escape probability of people near the target fire door when a fire occurs, and ensuring the safety of people's lives to the greatest extent.

[0015] When personnel are not in the above dangerous situations, it is more scientific and reasonable to control the closing degree of the target fire door according to the fire intensity. For example, when the fire is small, there is no need to completely close the target fire door immediately, which can ensure normal ventilation and other conditions to a certain extent while blocking the fire; when the fire is large, the target fire door can be quickly and tightly closed to effectively block the spread of fire and smoke, so that the fire door can better play its fire prevention and smoke isolation functions in the fire scene, improve the overall fire prevention efficiency, and reduce the damage caused by the fire to a larger area.

[0016] Since the entire process relies on sensor data and the judgment of various types of information to automatically control the degree of fire door closure, it changes the traditional relatively fixed and single fire door operation mode, realizes the intelligent management of fire door control, reduces the possible lag and inaccuracy of manual intervention, and improves the timeliness and accuracy of related operations when responding to fires.

[0017] Optionally, the step of controlling the closing degree of the target fire door according to the spreading speed of the fire includes:

[0018] According to the fire spreading speed, the threat distance d of the staff member whose fire spreading boundary is farthest from the target fire door is obtained;

[0019] The threat distance d is input into the pre-built speed model v=ckd / t to obtain the required escape speed v, where c and k are adjustment coefficients and t is the pre-set safety time.

[0020] Integrate the required escape speed V into prompt information output;

[0021] According to the desired escape speed v, the closing degree of the target fire door is controlled.

[0022] By adopting the above technical solution, by focusing on the staff whose fire spread boundary is farthest from the target fire door, obtaining their threat distance d, and giving priority to the situation of those who are in the most unfavorable position and have greater difficulty in escaping. Since they are farther away from the target fire door and face higher risks, this targeted measure ensures that these individuals who are prone to desperate situations will not be omitted when formulating response strategies, and the life safety of all people who may be threatened by fire is guaranteed to the greatest extent.

[0023] Integrating the required escape speed V into prompt information output can accurately give escape speed recommendations suitable for people at the farthest location based on their actual danger distance and the pre-set safety time t, so that they can clearly know the escape speed standard they need to achieve and arrange their escape actions reasonably, avoiding wasting time or blindly escaping in panic due to unclear required speed, thereby increasing the possibility of their successful escape.

[0024] Optionally, the control method further comprises:

[0025] Determine whether the threat distance d is less than a distance threshold;

[0026] If so, a second prompt message is output to prompt the staff to increase the escape speed.

[0027] By adopting the above technical solution, by setting a distance threshold and comparing it with the threat distance d, it is possible to keenly capture that the staff is in a relatively dangerous and urgent state away from the fire door; once it is determined that the threat distance d is less than the distance threshold, the second prompt information is output in time, so that the staff in this critical dangerous situation can know their critical situation at the first time, remind them to speed up their escape, avoid them missing the best escape opportunity due to not realizing the approaching danger, and enhance the timeliness of early warning of dangerous situations.

[0028] The second prompt information output clearly and explicitly requires the staff to increase their escape speed, so that they can clearly realize that escaping at a normal speed may not ensure safety, and they need to speed up their pace or adopt a more efficient escape method. This avoids the blindness and uncertainty that the staff may have when facing danger, and provides clear guidance for them to reasonably adjust their escape strategies in emergency situations, helping them to better deal with emergency and dangerous situations and try to escape from the fire threat area as soon as possible. In an emergency and dangerous scenario such as a fire, it is easy for the staff to panic, and clear prompt information can help them stabilize their emotions and stay calm to a certain extent.

[0029] When they received prompts to increase their escape speed, although they realized that the danger was increasing, they also knew clearly how to respond and had a specific direction of action. Compared with clueless panic, this targeted prompt helped the staff overcome panic and speed up their escape more rationally, thereby improving the psychological stability and coping ability of the entire group during fire emergencies.

[0030] Optionally, the step of controlling the closing degree of the target fire door according to the required escape speed includes:

[0031] Get the number of staff members n;

[0032] According to the number n of the workers, the length z of the last worker to be queued is obtained;

[0033] Get the distance between the last staff member and the target fire door ;

[0034] According to the distance , the queue length z and the escape speed v, and obtain the time it takes for the last staff member to pass through the target fire door ;

[0035] The duration The initial opening width W of the target fire door obtained in advance is input into the pre-built closing speed model to obtain the closing speed of the target fire door. ;

[0036] According to the closing speed , controlling the closing degree of the target fire door.

[0037] By adopting the above technical solution, the process combines the consideration of the escape speed of the farthest person with the control of the closing degree of the target fire door, and coordinates the escape of personnel and fire prevention and control work as a whole. While ensuring that the farthest person can safely pass through the target fire door within a reasonable time, the fire can be effectively prevented from spreading by accurately controlling the closing of the target fire door, preventing the fire from causing damage to a larger area, thereby improving the response efficiency of the entire fire emergency scenario, reducing casualties and property losses, and achieving more scientific and efficient emergency management.

[0038] Optionally, the closing speed model is ≥ , = ; z = ; m is the width of the staff.

[0039] Optionally, the control method further comprises:

[0040] Determine whether the staff is within a pre-established safety zone based on the staff location information;

[0041] If so, a sprinkler mechanism is controlled to perform sprinkler spraying, wherein the sprinkler mechanism is arranged at a boundary of the safety area away from the target fire door.

[0042] By adopting the above technical solution, it is a reasonable arrangement to set the sprinkler mechanism at the boundary of the safe area away from the target fire door. Such a layout allows the sprayed water or fire extinguishing agent to cover a wider area, especially in the direction where the fire may spread, to prevent the fire from quickly breaking through the safe area and threatening personnel and the relatively safe area on the other side of the target fire door. Moreover, spraying at a position far away from the target fire door can prevent water from directly rushing to the target fire door and affecting its normal closing function, while ensuring the fire extinguishing effect and the reliability of the subsequent fire door.

[0043] Optionally, the step of controlling the spraying mechanism to spray further includes:

[0044] The spraying intensity of the spraying mechanism is controlled according to the fire intensity of the fire.

[0045] By adopting the above technical solution, the spraying intensity of the sprinkler mechanism is controlled according to the fire intensity, realizing dynamic and precise adaptation of the fire extinguishing operation. When the fire is small, the spraying intensity can be appropriately reduced, which can not only effectively extinguish small fires and avoid unnecessary water damage and waste of water resources caused by excessive spraying, but also accurately control the scope of fire extinguishing, making the fire extinguishing operation more economical and efficient; in the case of a large fire, the spraying intensity is timely increased to ensure that the sprayed water or fire extinguishing agent can cover a larger area and have a stronger fire extinguishing and cooling ability, thereby more effectively suppressing the spread of the fire, enhancing the fire extinguishing effect, and enabling the sprinkler mechanism to better cope with the challenges brought by fires of different sizes.

[0046] In the second aspect, the present application provides a control system for a mine fire door, which adopts the following technical solution:

[0047] A control system for a mine fire door, comprising:

[0048] A data receiving module, used to receive sensor data sent by sensors around each fire door;

[0049] A judgment module, used to judge whether a fire occurs inside the mine based on the multiple sets of sensor data;

[0050] A position acquisition module is used to determine the target fire door according to the fire spread area after the judgment module determines that a fire has occurred, and obtain the personnel position information of the personnel around the target fire door;

[0051] The judgment module further judges whether the staff is on the fire spread path and between the target fire door and the fire spread boundary based on the staff position information;

[0052] A control module, used to control the closing degree of the target fire door according to the fire spread speed when the judgment module determines that the staff is on the fire spread path and is between the target fire door and the fire spread boundary; and used to control the closing degree of the target fire door according to the fire intensity when it is determined that the staff is not on the fire spread path.

[0053] By adopting the above technical solution, the fire situation is judged by receiving data from sensors around the fire door, and then the location information of the staff is obtained, which can accurately determine whether the personnel are in a dangerous fire spread path and between the target fire door and the fire spread boundary. In the case of being in such a dangerous position, the closing degree of the target fire door is controlled according to the fire spread speed. While ensuring the prevention of the spread of the fire, it is possible to leave enough time for the relevant personnel to evacuate safely, avoiding people being trapped in the dangerous area due to the target fire door closing too quickly, effectively improving the escape probability of people near the target fire door when a fire occurs, and ensuring the safety of people's lives to the greatest extent.

[0054] When personnel are not in the above dangerous situations, it is more scientific and reasonable to control the closing degree of the target fire door according to the fire intensity. For example, when the fire is small, there is no need to completely close the target fire door immediately, which can ensure normal ventilation and other conditions to a certain extent while blocking the fire; when the fire is large, the target fire door can be quickly and tightly closed to effectively block the spread of fire and smoke, so that the fire door can better play its fire prevention and smoke isolation functions in the fire scene, improve the overall fire prevention efficiency, and reduce the damage caused by the fire to a larger area.

[0055] Since the entire process relies on sensor data and the judgment of various types of information to automatically control the degree of fire door closure, it changes the traditional relatively fixed and single fire door operation mode, realizes the intelligent management of fire door control, reduces the possible lag and inaccuracy of manual intervention, and improves the timeliness and accuracy of related operations when responding to fires.

[0056] In a third aspect, the present application provides a terminal, which adopts the following technical solution:

[0057] A terminal, comprising:

[0058] A memory storing a control program of a mine fire door;

[0059] The processor is used to execute the program stored in the memory to implement the steps of the above-mentioned mine fire door control method.

[0060] In a fourth aspect, the present application provides a computer-readable storage medium, which adopts the following technical solution:

[0061] A computer-readable storage medium stores a computer program that can be loaded by a processor and execute the above-mentioned mine fire door control method.

[0062] In summary, the present application has at least the following beneficial effects:

[0063] 1. According to the sensor data, determine whether a fire has occurred, and obtain the personnel location information of the staff around the target fire door, and then determine whether the personnel position is on the fire spread path and whether it is between the target fire door and the fire spread boundary. The purpose is to judge the fire situation by receiving the data of the sensors around the fire door, and then obtain the position information of the staff, so as to accurately determine whether the personnel are in the dangerous fire spread path and between the target fire door and the fire spread boundary. For the situation in such a dangerous position, the closing degree of the target fire door is controlled according to the fire spread speed. While ensuring the prevention of the spread of the fire, it is possible to leave enough time for the relevant personnel to evacuate safely, and avoid people being trapped in the dangerous area due to the target fire door closing too quickly, which effectively increases the escape probability of people near the target fire door when a fire occurs, and maximizes the safety of people's lives.

[0064] When personnel are not in the above dangerous situations, it is more scientific and reasonable to control the closing degree of the target fire door according to the fire intensity. For example, when the fire is small, there is no need to completely close the target fire door immediately, which can ensure normal ventilation and other conditions to a certain extent while blocking the fire; when the fire is large, the target fire door can be quickly and tightly closed to effectively block the spread of fire and smoke, so that the fire door can better play its fire prevention and smoke isolation functions in the fire scene, improve the overall fire prevention efficiency, and reduce the damage caused by the fire to a larger area.

[0065] Since the entire process relies on sensor data and the judgment of various types of information to automatically control the degree of fire door closure, it changes the traditional relatively fixed and single fire door operation mode, realizes the intelligent management of fire door control, reduces the possible lag and inaccuracy of manual intervention, and improves the timeliness and accuracy of related operations when responding to fires.

[0066] 2. The purpose of judging that the threat distance d is less than the distance threshold is to keenly capture that the staff is in a relatively dangerous and urgent state from the target fire door by setting the distance threshold and comparing it with the threat distance d; once it is judged that the threat distance d is less than the distance threshold, the second prompt information is output in time to let the staff in this critical dangerous situation know their critical situation at the first time, remind them to speed up their escape, avoid them missing the best escape opportunity due to not realizing the approaching danger, and enhance the timeliness of early warning of dangerous situations.

[0067] The second prompt information output clearly and explicitly requires the staff to increase their escape speed, so that they can clearly realize that escaping at a normal speed may not ensure safety, and they need to speed up their pace or adopt a more efficient escape method. This avoids the blindness and uncertainty that the staff may have when facing danger, and provides clear guidance for them to reasonably adjust their escape strategies in emergency situations, helping them to better deal with emergency and dangerous situations and try to escape from the fire threat area as soon as possible. In an emergency and dangerous scenario such as a fire, it is easy for the staff to panic, and clear prompt information can help them stabilize their emotions and stay calm to a certain extent.

[0068] When they received prompts to increase their escape speed, although they realized that the danger was increasing, they also knew clearly how to respond and had a specific direction of action. Compared with clueless panic, this targeted prompt helped the staff overcome panic and speed up their escape more rationally, thereby improving the psychological stability and coping ability of the entire group during fire emergencies.

[0069] 3. The purpose of judging whether the personnel location information is within the pre-constructed safety area is to set the sprinkler mechanism at the boundary of the safety area away from the target fire door, which is a reasonable arrangement after consideration. Such a layout allows the sprayed water or fire extinguishing agent to cover a wider area, especially in the direction where the fire may spread, to prevent the fire from quickly breaking through the safety area and threatening personnel and the relatively safe area on the other side of the target fire door. Moreover, spraying at a location far away from the fire door can prevent water from directly rushing to the target fire door and affecting its normal closing function, while ensuring the fire extinguishing effect and the reliability of the subsequent target fire door.

[0075] To make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will be combined with the appended drawings of the embodiments of the present invention. Figure 1 -Attached Figure 4 , the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0076] The first embodiment of the present application discloses a method for controlling a mine fire door. Figure 1 As an implementation of the control method, the control method may include S110-S180:

[0077] S110, receiving sensor data sent by sensors around each fire door;

[0078] S120, judging whether a fire occurs inside the mine based on the multiple sets of sensor data;

[0079] S130, if yes, determine the target fire door according to the fire spreading area;

[0080] S140, if not, return to S110;

[0081] S150, obtaining personnel position information of personnel around the target fire door;

[0082] S160, based on the personnel position information, determining whether the personnel are on the fire spread path and between the target fire door and the fire spread boundary;

[0083] S170, if yes, control the closing degree of the target fire door according to the spreading speed of the fire;

[0084] S180: If not, the closing degree of the target fire door is controlled according to the fire intensity.

[0085] Specifically, sensors are arranged on both sides of each fire door in the mine, including smoke detectors, temperature sensors, etc. In addition, cameras are arranged on both sides of each fire door to collect image information on the side where the camera is located. By analyzing the image information and the sensor data sent by the sensor, it is determined whether a fire has occurred inside the mine. When the data of the smoke detector and temperature sensor are abnormal, such as the temperature is too high or the smoke concentration becomes high, it means that a fire may have occurred; further combined with the image collected by the camera, if there are firelight and flame features in the image collected by the camera, it is determined that a fire has occurred.

[0086] After confirming that a fire has occurred, the target fire door is determined based on the fire spread path. The fire spread path is tracked by monitoring temperature changes at different locations and combining the signals fed back by multiple smoke detectors. Areas where the temperature rises faster and the smoke density changes are usually the direction of fire spread.

[0087] The location of the staff can be determined by monitoring the location of the staff's mobile terminal. The location of the fire door can be obtained in advance, and the location of the fire source can be approximately determined based on the data analysis of the sensor. The location of the fire source, the location of the fire door, and the location of the staff can be converted into two-dimensional coordinate points, so that it can be determined whether the staff's location is on the fire spread path and whether it is between the fire door and the fire source.

[0088] The fire intensity can be obtained by analyzing the images collected by the camera and combining them with sensor data analysis. For example, when the fire is small, such as when the fire has just started, the flame area is small, the temperature rise is not obvious, and the smoke concentration is low, the fire door can be kept half-open. The purpose of this is to prevent the spread of the fire to a certain extent while ensuring ventilation. Because in the early stage of the fire, proper ventilation helps to exhaust smoke and harmful gases, creating a relatively good environment for personnel evacuation.

[0089] As the fire develops, when the flame area begins to expand, the temperature rises rapidly, and the smoke density increases, the fire door can be partially closed. For example, it can be closed to a width that is only wide enough for one or a few people to pass through. This degree of closure can effectively prevent the rapid spread of fire and smoke while ensuring that people can continue to evacuate. Taking a hotel corridor fire as an example, if the fire has spread to some rooms, the fire door can be partially closed to allow people in the room to evacuate to a safe area as soon as possible, while preventing flames and smoke from pouring into the corridor.

[0090] When the fire is very large, the flame height exceeds a certain range, the temperature rises sharply, the smoke is thick and spreads quickly, the fire door should be completely closed.

[0091] Reference Figure 2, a specific step of S170 may include S171-S174:

[0092] S171, according to the fire spreading speed, obtaining the threat distance d of the staff member whose fire spreading boundary is farthest from the target fire door;

[0093] S172, input the threat distance d into the pre-built speed model v=ckd / t to obtain the required escape speed v, where c and k are adjustment coefficients, and t is the pre-set safety time;

[0094] S173, integrating the required escape speed v into prompt information output;

[0095] S174, controlling the closing degree of the target fire door according to the required escape speed v.

[0096] Specifically, the boundary of the area where the temperature starts to rise sharply can be roughly determined as the fire spread boundary. For example, in a building, as the fire spreads, the temperature of the area closer to the fire source will rise first, and the boundary where the temperature transitions from the normal range to the high temperature area may be the fire spread boundary; smoke detectors can also be used to determine that when the smoke concentration drops sharply from a high value to a low value, it may be the fire spread boundary, etc.

[0097] After determining the fire spread boundary, the location of the fire spread boundary can be determined based on the location of the temperature sensor or smoke detector at the boundary; then, based on the staff position and the location of the target fire door, the distance between each staff member and the target fire door is determined, and from multiple distances, the farthest staff member from the target fire door is determined, and then the threat distance d is determined based on the location of the farthest staff member and the location of the fire spread boundary.

[0098] The c and k in the velocity model can be set and modified by the back-end management personnel, or they can be determined based on relevant data from historical fires.

[0099] A voice alarm is also installed at each fire door. The voice alarm at the target fire door will sound an alarm when a fire occurs and can output prompt information, including "the speed at which you should escape". After the voice alarm is sounded, it will sound a voice alarm prompt every 60 seconds within 10 minutes; if it is not eliminated after more than 10 minutes (it can be eliminated manually after on-site inspection or remotely), the target fire door will automatically close, and the voice alarm will broadcast a prompt every 30 seconds that "the fire door is shut down and cannot be passed".

[0100] Reference Figure 3 , the specific steps of S174 may include S1741-S1746:

[0101] S1741, obtain the number of staff members n;

[0102] S1742, according to the number of workers n, obtain the length z of the last worker to be queued;

[0103] S1743, obtain the distance between the last staff member and the target fire door ;

[0104] S1744, according to distance , the queue length z and the escape speed v, and obtain the time it takes for the last staff member to pass through the target fire door ;

[0105] S1745, the duration The target fire door initial opening width W obtained in advance is input into the pre-built closing speed model to obtain the closing speed of the target fire door ;

[0106] S1746, according to the closing speed and duration , control the closing degree of the target fire door.

[0107] Specifically, the number of workers can be determined according to the number of positions of the workers' mobile terminals. The queue length z of the last worker should be = , m is the width of the staff, which can be set through the background. = ; The closing speed model is ≥ .

[0108] For example, assuming there are 10 staff members, each staff member has a width of m = 0.5m, and the target fire door has an initial opening width of W = 1.5m. The staff member's escape speed should be =1m / s, the distance between the last worker and the target fire door =10m, then the time it takes for the last worker to pass through the target fire door =14.5s; then the closing speed of the target fire door ≤ =0.1m / s, the target fire door should run at a speed of 0.1m / s for 15s and close gradually.

[0109] Furthermore, when the last staff member escapes, it is determined in real time whether the threat distance d is less than the distance threshold. If so, a second prompt message is output to prompt the staff member to increase the escape speed; if not, no response is given.

[0110] Furthermore, the control method may also include:

[0111] The personnel location information is used to determine whether the staff is in the pre-built safe area. If so, the sprinkler mechanism is controlled to spray. The sprinkler mechanism is set at the boundary of the safe area away from the target fire door to suppress the flame. The sprinkler mechanism is a conventional sprinkler structure. In addition, when spraying, the sprinkler mechanism's spraying intensity can also be controlled according to the size of the fire.

[0112] The implementation principle of this embodiment is:

[0113] Receive the sensor data sent by the sensors around each fire door, and judge whether a fire occurs inside the mine based on multiple sets of sensor data. If so, determine the target fire door based on the fire spread area, and obtain the personnel position information of the staff around the target fire door. Then, based on the personnel position information, determine whether the staff is on the fire spread path and whether it is between the fire door and the fire spread boundary. If so, obtain the threat distance d of the staff farthest from the fire spread boundary to the target fire door based on the fire spread speed, input the threat distance d into the pre-built velocity model v=ckd / t, and obtain the required escape velocity. degree v; integrate the expected escape speed V into prompt information output; then obtain the number of staff members n, and then obtain the queue length of the last staff member according to the number of staff members n; then obtain the distance between the last staff member and the target fire door, and then obtain the time it takes for the last staff member to pass through the target fire door according to the distance, the queue length and the expected escape speed, and then input the time and the initial opening width of the target fire door into the closing speed model to obtain the closing speed of the target fire door, and control the closing degree of the target fire door according to the closing speed and the time it takes for the last staff member to pass through the target fire door.

[0114] Based on the above method embodiment, the second embodiment of the present application discloses a control system for a mine fire door. Figure 4 , the regulatory system may include:

[0118] The judgment module 102 further judges whether the staff is on the fire spread path and between the target fire door and the fire spread boundary based on the personnel position information;

[0119] The control module 104 is used to control the closing degree of the target fire door according to the fire spread speed when the judgment module 102 determines that the staff is on the fire spread path and is between the fire door and the fire spread boundary; and is used to control the closing degree of the target fire door according to the fire intensity when it is determined that the staff is not on the fire spread path.

[0120] The modules of the control system of the mine fire door correspond one to one with the control method of the mine fire door, and no further details will be given here.
