[0064] See also Figure 1-2 As shown, in some embodiments of the present application, this embodiment provides an escape corridor for high-rise fire evacuation, including:

[0065] The escape corridor body 100 is arranged on the outer wall of the building 200;

[0066] A protective net is arranged outside the escape corridor body, the protective net is made of fire-resistant material, and is used to prevent personnel from accidentally falling when using the escape corridor body 100;

[0067] Escape holes: a plurality of escape holes are provided in the vertical direction on one side of the escape corridor body 100 close to the building 200;

[0068] An escape duct 110, one end of which is connected to the escape hole, and the other end of which extends into the interior of the building 200, and a fire door is provided at the other end of the escape duct 110;

[0069] A waterproof layer is provided on the outside of the escape pipe 110, and is used to prevent rainwater from entering the inside of the escape pipe 110;

[0070] The slide assembly is vertically arranged inside the escape corridor body 100. An escape platform 140 connected to the escape hole is arranged on one side of the slide assembly close to the building 200. The slide assembly is used to slide the evacuated personnel from the escape hole to the ground.

[0071] Emergency lighting components are arranged inside the escape corridor body 100 and inside the escape duct 110;

[0072] The smoke exhaust assembly 130 is arranged inside the escape duct 110;

[0073] The alarm device is arranged on the escape corridor body 100 and is used to sound an alarm when a fire occurs.

[0074] It can be seen that when a fire occurs, the alarm device of the escape corridor body 100 will be immediately activated, emitting an alarm sound and warning lights to remind people in the building 200 to evacuate quickly; the emergency lighting component will automatically turn on to ensure that there is sufficient lighting inside the escape corridor and the escape duct 110 so that people can find the escape route safely and quickly in an emergency; after reaching the escape hole, people can quickly enter the spiral slide 122 through the escape platform 140 and quickly slide down to the ground by gravity; the spiral slide 122 not only saves space, but also can effectively disperse the escapees to avoid crowding and trampling accidents life; a buffer device is provided at the bottom of the slide to reduce the impact force when people land; during the escape process, the smoke exhaust component 130 will start the exhaust fan 131 to exhaust the smoke in the escape duct 110 to ensure the clarity of the escape passage. At the same time, the waterproof layer ensures that the inside of the escape duct 110 will not accumulate water due to external rainwater, affecting the evacuation efficiency; the control module will monitor the smoke concentration, the number of people, the weight characteristic data of people and the moving speed characteristic data in the escape duct 110 in real time, and intelligently adjust the opening number of the exhaust fan 131 through the data collected by the sensor group to achieve the best smoke exhaust effect and energy saving effect.

[0075] It can be understood that the high-rise fire escape corridor provided in this embodiment provides a safe, efficient and intelligent evacuation solution by comprehensively considering various emergency situations during fire, thereby greatly improving the evacuation efficiency and safety during fire.

[0076] Specifically, the slide assembly includes:

[0077] A fixed shaft 121 is vertically arranged inside the escape corridor body 100, the top end of the fixed shaft 121 is connected to the top of the escape corridor body 100, and the bottom end of the fixed shaft 121 extends into the ground;

[0078] The spiral slide 122 is arranged outside the fixed shaft 121, and the outer wall of the spiral slide 122 is fixedly connected to the inner wall of the escape corridor body 100. The spiral slide 122 is provided with a plurality of entrances on the side close to the building 200, and the entrances are connected to the escape hole through the escape platform 140.

[0079] It is understandable that the fixed shaft 121 is used to support the entire slide assembly to ensure that it remains stable during use. The structural design of the spiral slide 122 enables it to withstand a large weight while ensuring smooth and safe evacuation. The setting of the entrance takes into account the evacuation needs of different floors, so that people on each floor can quickly enter the escape system.

[0080] Specifically, emergency lighting components include:

[0081] An exit indicator light is provided at the exit of the escape duct 110 to indicate the escape direction;

[0082] Emergency lighting lamps are evenly distributed on the inner walls of the escape corridor body 100 and the escape duct 110;

[0083] The emergency power supply is arranged inside the escape corridor body 100 and is connected to the emergency lighting. The emergency power supply is used to provide power to the emergency lighting in case of power failure.

[0084] It is understood that the design of the emergency lighting assembly ensures that in an emergency, whether the power supply of the building 200 is normal or not, the escape corridor and the escape duct 110 can be adequately illuminated. The exit indicator lights provide clear escape directions for escaping personnel, while the emergency lighting ensures that each part of the escape path is clearly visible, avoiding confusion and disorientation during escape. The setting of the emergency power supply further enhances the reliability of the system, and even in the event of a power outage, it can ensure the normal operation of the lighting equipment, providing important safety guarantees for personnel evacuation.

[0085] Specifically, the smoke exhaust assembly 130 includes:

[0086] There are a plurality of exhaust fans 131, which are evenly arranged on both sides of the escape duct 110, and the exhaust fans 131 are used to exhaust smoke in the escape duct 110 when a fire occurs;

[0087] The smoke exhaust duct 132 is connected to the air outlet end of the exhaust fan 131 . The smoke exhaust duct 132 is used to exhaust the smoke out of the escape duct 110 .

[0088] It is understandable that the setting of the exhaust fan 131 takes into account the rapid exhaust of smoke in the escape duct 110 to ensure air circulation in the escape passage and reduce the harm of smoke to the evacuated personnel. The design of the smoke exhaust duct 132 ensures that the smoke can be effectively guided to a safe area to avoid secondary pollution to the surrounding environment. When a fire occurs, the rapid response and efficient smoke exhaust function of the smoke exhaust component 130 provide a safer environment for personnel evacuation, greatly improving the efficiency and safety of evacuation.

[0089] Specifically, it also includes:

[0090] A sensor group is arranged inside the escape duct 110;

[0091] A control module, connected to the sensor group, the emergency lighting assembly, the smoke exhaust assembly 130 and the alarm device, the control module includes a collection unit, a judgment unit and an adjustment unit;

[0092] The collection unit is configured to collect smoke concentration data inside the escape duct 110, and determine the initial opening number of the exhaust fan 131 according to the smoke concentration data;

[0093] The judgment unit is configured to control the collection unit to collect the number of people inside the escape duct 110, and judge whether to adjust the initial opening number according to the number of people;

[0094] The adjustment unit is configured to, when it is determined that the initial opening quantity is to be adjusted, control the collection unit to collect the weight characteristic data and the movement speed characteristic data of the personnel inside the escape duct 110, and calculate the quantity impact index based on the weight characteristic data and the movement speed characteristic data of the personnel; obtain the adjustment quantity based on the quantity impact index, adjust the initial opening quantity based on the adjustment quantity, and obtain the final adjustment quantity.

[0095] It is understandable that, through the intelligent control function of the control module, the number of exhaust fans 131 opened can be dynamically adjusted according to real-time data such as smoke concentration, number of people, weight and movement speed. This intelligent adjustment mechanism can not only effectively exhaust the smoke in the escape duct 110, but also achieve energy saving while ensuring smoke exhaust efficiency. For example, when the smoke concentration is high, the system will automatically increase the number of exhaust fans 131 opened to speed up the smoke exhaust speed; when the smoke concentration is low, the number of exhaust fans 131 opened will be reduced to save energy. In addition, the control module can also calculate the quantity impact index based on the weight and movement speed characteristic data of the personnel, so as to more accurately adjust the number of exhaust fans 131 opened, ensuring that the best smoke exhaust effect can be provided in a variety of situations, which not only improves the evacuation efficiency, but also reduces the operating cost, providing an innovative solution for fire safety evacuation in high-rise buildings.

[0096] Specifically, when determining the initial opening number of the exhaust fan 131 according to the smoke concentration data, it includes:

[0097] Extract features from smoke density data to obtain smoke density feature values;

[0098] Comparing the smoke density characteristic value with the first smoke density characteristic value and the second smoke density characteristic value, and determining the initial opening quantity according to the comparison result; wherein the first smoke density characteristic value is less than the second smoke density characteristic value;

[0099] When the smoke density characteristic value is less than or equal to the first smoke density characteristic value, determining that the initial opening quantity is the first quantity;

[0100] When the smoke density characteristic value is greater than the first smoke density characteristic value and less than or equal to the second smoke density characteristic value, determining that the initial opening quantity is the second quantity;

[0101] When the smoke density characteristic value is greater than the second smoke density characteristic value, it is determined that the initial opening quantity is the third quantity.

[0102] It is understandable that the first number < the second number < the third number. By setting different smoke concentration thresholds, various fire situations can be flexibly responded to. When the smoke concentration is low, the system will start a smaller number of exhaust fans 131 to save energy; as the smoke concentration increases, the system will gradually increase the number of exhaust fans 131 to ensure the clarity of the escape route. This hierarchical control strategy not only improves the smoke exhaust efficiency, but also reduces unnecessary energy consumption, reflecting the intelligent system design and the concept of energy saving and environmental protection.

[0103] Specifically, when determining whether to adjust the initial opening quantity based on the number of personnel, it includes:

[0104] Compare the number of personnel with the threshold number of personnel, and determine whether to adjust the initial opening number based on the comparison result;

[0105] When the number of personnel is less than or equal to the threshold number of personnel, it is determined that the initial opening number will not be adjusted;

[0106] When the number of personnel is greater than the personnel number threshold, it is determined to adjust the initial opening number.

[0107] It is understandable that by setting a reasonable threshold for the number of people, the system can dynamically adjust the number of exhaust fans 131 that are turned on according to the actual evacuation situation. When the number of people to be evacuated does not exceed the threshold, the number of exhaust fans 131 initially set is maintained to ensure the basic smoke exhaust effect; once the number of people to be evacuated exceeds the threshold, the system will automatically increase the number of exhaust fans 131 that are turned on to cope with more smoke generated by the increase in the number of people, ensure air circulation in the escape passage, and ensure the safety of the evacuated personnel. This dynamic adjustment mechanism based on real-time data makes the smoke exhaust system more intelligent and efficient, and provides more accurate and reliable protection for the safe evacuation of high-rise building fires.

[0108] Specifically, when calculating the quantity impact index based on the weight characteristic data and movement speed characteristic data of personnel, it includes:

[0109] Extract the characteristics of personnel weight and moving speed respectively to obtain the average personnel weight and average moving speed;

[0110] The quantity impact index is calculated based on the average personnel weight and the average moving speed; wherein the quantity impact index is obtained by weighted calculation of the average personnel weight and the average moving speed.

[0111] Specifically, the adjusted quantity is obtained according to the quantity impact index, and the initial opening quantity is adjusted according to the adjusted quantity. When the final adjusted quantity is obtained, it includes:

[0112] Setting an adjustment quantity interval, the adjustment quantity interval includes a first adjustment quantity, a second adjustment quantity and a third adjustment quantity;

[0113] Comparing the quantity impact index with a first quantity impact index threshold and a second quantity impact index threshold, and determining the adjustment quantity according to the comparison result; wherein the first quantity impact index threshold is less than the second quantity impact index threshold;

[0114] When the quantity impact index is less than or equal to the first quantity impact index threshold, the adjusted quantity is determined to be the first adjusted quantity, and the sum of the first adjusted quantity and the initial opening quantity is taken as the final adjusted quantity;

[0115] When the quantity impact index is greater than the first quantity impact index threshold and less than or equal to the second quantity impact index threshold, the initial opening quantity is determined to be the second adjustment quantity, and the sum of the second adjustment quantity and the initial opening quantity is used as the final adjustment quantity;

[0116] When the quantity impact index is greater than the second quantity impact index threshold, the initial opening quantity is determined to be the third adjustment quantity, and the sum of the third adjustment quantity and the initial opening quantity is taken as the final adjustment quantity.

[0117] It is understandable that the first adjustment number is less than the second adjustment number and less than the third adjustment number. Through this weighted calculation method, the system can comprehensively consider the impact of the weight and movement speed of personnel on the smoke exhaust efficiency, so as to more accurately adjust the number of exhaust fans 131 that are turned on. For example, when the average weight of the evacuated personnel is large or the movement speed is slow, the system will increase the number of exhaust fans 131 that are turned on to ensure that the smoke can be quickly discharged to avoid affecting the evacuation efficiency due to excessive smoke concentration. On the contrary, if the average weight is light or the movement speed is fast, the system will reduce the number of exhaust fans 131 that are turned on to save energy. This dynamic adjustment mechanism based on personnel characteristic data not only improves the response speed and smoke exhaust efficiency of the smoke exhaust system, but also further optimizes energy use, providing a more intelligent and energy-saving solution for the safe evacuation of high-rise building fires.

[0120] S200: collecting the number of people inside the escape duct 110, and determining whether to adjust the initial opening number according to the number of people;

[0121] S300: when it is determined that the initial opening quantity is to be adjusted, the weight characteristic data and the moving speed characteristic data of the personnel inside the escape duct 110 are collected, and the quantity impact index is calculated according to the weight characteristic data and the moving speed characteristic data of the personnel;
