[0043] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0044] With the rapid growth of urban populations, elevators have become an indispensable part of people's lives and a crucial piece of building equipment in modern urbanization. As an enclosed space, elevator safety is increasingly important to passengers. If passengers bring flammable materials into an elevator and a fire breaks out inside, it poses a serious threat to both passengers and the building.

[0045] For example, if a passenger pushes an electric bicycle into an elevator, and the lithium battery of the electric bicycle catches fire during elevator operation, causing a fire, the passenger will be unable to escape in time because the elevator cannot be opened in time, which could lead to a serious safety accident.

[0046] To address the aforementioned technical problems, this application proposes a method for controlling the safe use of flammable materials in elevators. Applied to a control terminal, the method involves: upon acquiring elevator information about flammable materials from an information acquisition module, determining whether the flammable material is placed within a target placement location based on this information; wherein the target placement location corresponds to a fire emergency isolation device; if the flammable material is placed within the target placement location, the elevator is controlled to operate; if, during elevator operation, fire information about the flammable material is acquired from the information acquisition module, the fire emergency isolation device is controlled to isolate the flammable material. In other words, this application, through strict control of flammable material identification and placement, ensures that flammable materials are placed within the target placement location corresponding to the fire emergency isolation device. This allows the fire emergency isolation device to isolate the flammable material within the target placement location in the event of a fire or other fire accident while the flammable material is in the elevator, thus ensuring the safety of passengers in the elevator.

[0047] Reference Figure 1 This application provides a method for controlling the safe use of flammable materials in an elevator, applied to a control terminal, comprising the following steps:

[0048] Step S10: When the elevator information of flammable items in the elevator is obtained from the information collection module, it is determined whether the placement of the flammable items is within the target placement position based on the elevator information.

[0049] It should be noted that the target placement location corresponds to a fire emergency isolation device; specifically, the fire emergency isolation device includes a floor movable module, a support module, and a fire extinguishing module; the floor movable module is used to support the flammable materials, and in the event of a fire involving the flammable materials inside the elevator, the floor movable module allows the flammable materials to fall under the support module below the elevator car under gravity, and then the fire extinguishing module extinguishes the fire. Therefore, in this embodiment, the target placement location is located above the floor movable module.

[0050] In practical applications, the information acquisition module collects image information inside the elevator and analyzes it to identify whether flammable materials are present and their placement area on the elevator car floor. This provides identification information and placement area information for the flammable materials. This information is then sent to the control terminal. The control terminal controls the elevator's operation based on the received information. If the identification information indicates no flammable materials are present, the control terminal maintains normal elevator operation. If the identification information indicates the presence of flammable materials, the control terminal compares the flammable material's placement location with a target placement location to determine if the flammable material is within the target location. If the flammable material is within the target location, the control terminal controls the elevator to operate. If the flammable items are not placed in the target location, the control terminal will stop the elevator and control the voice prompt module to output elevator correction information to the passengers, so that the passengers can correct the placement of the flammable items based on the elevator correction information.

[0051] It should be noted that the elevator information includes the identification information of the flammable items and the information on the placement area of ​​the flammable items. Further, the identification information of the flammable items includes whether flammable items are present or not; the information on the placement area of ​​the flammable items refers to the placement area of ​​the flammable items on the elevator car floor.

[0052] The information acquisition module includes an image recognition device, which can be installed on the upper inner wall of the elevator car. The image recognition device collects image information inside the elevator, identifies whether there are flammable materials inside the elevator, and obtains information on the placement area of ​​flammable materials on the elevator car floor, so as to obtain the identification information of flammable materials and the placement area information of flammable materials.

[0053] It should be noted that the image recognition device uses existing equipment. This device can recognize and analyze images, converting them into digital information through analysis and feature extraction. A comparison algorithm is then used to match these digitally, ultimately achieving the purpose of recognition. Specifically, the image recognition device analyzes and extracts features from images inside the elevator, and uses a comparison algorithm to identify whether flammable materials are present inside the elevator and their location.

[0054] Step S20: If the flammable material is placed within the target placement location, control the elevator to operate.

[0055] It should be noted that the control terminal determines whether the placement of flammable materials is within the target placement location based on the received information about the placement area of ​​flammable materials, and outputs a judgment result accordingly. This judgment result includes normal placement and abnormal placement. Normal placement corresponds to the flammable materials being placed within the target placement location, while abnormal placement corresponds to the flammable materials being placed outside the target placement location. The placement of flammable materials within the target placement location means that the flammable materials are located within the target placement location; flammable materials should ideally not be placed on the edge of the target placement location to avoid interfering with the fire emergency isolation device's isolation operation.

[0056] In practical applications, if the flammable item is placed within the target placement location, and the control terminal outputs a judgment result indicating normal placement, then the control terminal controls the elevator to operate normally. If the flammable item is not placed within the target placement location, and the control terminal outputs a judgment result indicating abnormal placement, then the control terminal controls the elevator to stop operating and controls the voice prompt module to output elevator correction information to passengers, so that passengers can correct the placement of the flammable item based on the elevator correction information.

[0057] It should be noted that the voice prompt module is used to verbally notify passengers that flammable items are not placed in the target location, and to remind passengers to place the flammable items in the target location. After hearing the voice prompt, passengers will correct the placement of the flammable items and place them in the target location.

[0058] It should be noted that after controlling the elevator to stop running and controlling the voice prompt module to output elevator correction information to passengers so that passengers can correct the placement of flammable items based on the elevator correction information, the process further includes: re-acquiring the corrected placement position of the flammable items from the information acquisition module and determining whether the corrected placement position of the flammable items is within the target placement position.

[0059] In practical applications, after the voice prompt module instructs passengers to place flammable items in the target location, the information acquisition module re-acquires image information inside the elevator, analyzes and extracts features from the images, converts the images into digital information, and uses a comparison algorithm to match and identify the corrected placement position of the flammable items inside the elevator, obtaining the corrected placement area information. This corrected placement area information is then sent to the control terminal. The control terminal receives the corrected placement area information and determines whether the corrected placement position of the flammable items is within the target location. If the corrected placement position is within the target location, the control terminal outputs a judgment result of normal placement and controls the elevator to operate. If the corrected placement of the flammable items is not within the target placement position, the control terminal outputs a judgment result of abnormal placement, controls the elevator to stop running, and controls the voice prompt module to continue to output elevator correction information to the passengers, so that the passengers can correct the placement of the flammable items again based on the elevator correction information, until the placement of the flammable items is within the target placement position, and then the control terminal controls the elevator to run.

[0060] Step S30: If fire information of the flammable material is obtained from the information acquisition module during the operation of the elevator, control the fire emergency isolation device to isolate the flammable material.

[0061] In some embodiments, the information acquisition module further includes a smoke detector. This smoke detector utilizes physical changes in gas to detect fire hazards, smoke concentration, and temperature at the accident site. It measures changes in the composition and quantity of various substances in the air by detecting gas flow and converts this signal into an electrical signal, which is then fed back to the control terminal to determine whether a fire has occurred inside the elevator. The smoke detector can be an infrared smoke detector, an ultrasonic smoke detector, or an electronic smoke detector. These types of smoke detectors are all existing technologies and will not be described in detail here.

[0062] In practical applications, obtaining fire information about the flammable materials from the information acquisition module and controlling the fire emergency isolation device to isolate the flammable materials includes: obtaining fire information about the flammable materials from the information acquisition module; wherein the fire information includes flame information, smoke information, and temperature information; determining whether a fire has occurred in the flammable materials inside the elevator based on the fire information; and if a fire has occurred in the flammable materials inside the elevator, controlling the fire emergency isolation device to isolate the flammable materials.

[0063] It should be noted that during the elevator's operation, the information acquisition module collects smoke and temperature information inside the elevator based on the smoke detector, and simultaneously collects fire information inside the elevator based on the image recognition device. The smoke, temperature, and fire information are then fed back to the control terminal, enabling the control terminal to identify and determine whether a fire has occurred inside the elevator based on the collected information. The technical solution described in this application, which uses both a smoke detector and an image recognition device to jointly identify whether a fire has occurred inside the elevator, can improve fire identification efficiency and accuracy.

[0064] In practical applications, during the operation of the elevator, if the smoke detector detects smoke and / or high-temperature gas in flammable materials inside the elevator, it generates smoke and / or temperature information and sends this information to the control terminal. Based on the received smoke and / or temperature information, the control terminal analyzes and determines whether a fire has occurred inside the elevator. If the determination result is that a fire has occurred, the control terminal controls the fire emergency isolation device to isolate the flammable materials; if the determination result is that no fire has occurred, the control terminal controls the elevator to operate normally.

[0065] In practical applications, during the operation of the elevator, if the image recognition device collects and identifies the flame information of flammable materials inside the elevator, it sends the flame information to the control terminal. Based on the received flame information, the control terminal analyzes and determines whether a fire has occurred inside the elevator. If the determination result is that a fire has occurred, the control terminal controls the fire emergency isolation device to isolate the flammable materials, and the control terminal controls the elevator to stop at the nearest floor so that passengers can escape the elevator car as soon as possible. If the determination result is that no fire has occurred, the control terminal controls the elevator to operate normally.

[0066] In practical applications, during elevator operation, if the smoke detector detects smoke and / or high-temperature gas from flammable materials inside the elevator, and the image recognition device detects flames from flammable materials inside the elevator, the smoke detector sends smoke and / or temperature information to the control terminal, and the image recognition device sends flame information to the control terminal. The control terminal receives the smoke and / or temperature and flame information and analyzes and determines whether a fire has occurred inside the elevator. If the determination indicates a fire, the control terminal controls the fire emergency isolation device to isolate the flammable materials, and the control terminal stops the elevator at the nearest floor to allow passengers to escape the elevator car as quickly as possible. If the determination indicates no fire has occurred, the control terminal controls the elevator to operate normally.

[0067] In practical applications, if the judgment result is that a fire has occurred, the control terminal will use the voice prompt module to remind passengers to stand in an area away from the target placement location. This will prevent passengers from being accidentally dropped when the fire emergency isolation device drops flammable materials through the movable base module, thus further ensuring passenger safety while riding the elevator.

[0068] In practical applications, if a fire occurs in the flammable materials inside the elevator, the fire emergency isolation device is controlled to isolate the flammable materials. This includes: if a fire occurs in the flammable materials inside the elevator, the fire emergency isolation device is controlled to extend and retract the base plate of the target placement position so that the flammable materials fall to the bottom of the elevator car under the action of gravity.

[0069] It should be noted that when the base plate of the target placement position of the fire emergency isolation device is extended or retracted, the target placement position becomes hollow. That is, at this time, the area below the flammable material is hollow, and the target placement position can no longer support the flammable material. Under the action of gravity, the flammable material falls to the bottom of the elevator car, so that the flammable material is isolated.

[0070] In practical applications, after obtaining fire information of the flammable material from the information acquisition module and controlling the fire emergency isolation device to isolate the flammable material, the method further includes: obtaining the current floor information of the elevator; obtaining the nearest floor information of the elevator based on the current floor information of the elevator; and controlling the elevator to open the elevator door after reaching the nearest floor based on the nearest floor information, so that passengers can escape from the elevator car.

[0071] It should be noted that if a fire breaks out in the elevator containing flammable materials, the control terminal will obtain the elevator's current floor information and control the elevator to stop at the nearest floor. For example, if a fire breaks out in the elevator while it is ascending to the 5th floor, the control terminal will determine that the elevator is currently on the 5th floor and will control the elevator to continue ascending and stop at the 6th floor, allowing passengers to escape from the 6th floor. Similarly, if a fire breaks out in the elevator while it is descending to the 5th floor, the control terminal will determine that the elevator is currently on the 5th floor and will control the elevator to continue ascending and stop at the 4th floor, allowing passengers to escape from the 4th floor.

[0072] In addition, when the elevator stops at the nearest floor, the control terminal can also control the voice prompt module to remind passengers to evacuate in an orderly manner, so as to avoid other safety accidents caused by passengers panicking.

[0073] In addition, if a fire breaks out in the flammable materials inside the elevator, the control terminal can also send a fire alarm to the elevator management personnel's management terminal, so that the elevator management personnel can detect the fire in time and report it in a timely manner.

[0074] In practical applications, the fire emergency isolation device includes a floor movable module, a support module, and a fire extinguishing module; the target placement position is the position corresponding to the floor movable module; the step of controlling the fire emergency isolation device to isolate the flammable materials includes: controlling the floor movable module to open, so that the flammable materials fall into the support module below the elevator car under the action of gravity; and controlling the fire extinguishing module to extinguish the fire on the isolated flammable materials.

[0075] It should be noted that the floor movable module is used to support the flammable materials, and in the event of a fire involving the flammable materials in the elevator, the floor can move to make the target placement position open, that is, the area below the flammable materials is open, and the floor movable module in the target placement position can no longer support the flammable materials. Under the action of gravity, the flammable materials fall into the supporting module below the elevator car, and then the fire extinguishing module extinguishes the fire.

[0076] Reference Figure 2 Based on the same inventive concept, embodiments of this application also provide: a flammable materials safety elevator control system, comprising:

[0077] The information acquisition module is used to acquire elevator access information and fire information of flammable materials, and send the elevator access information and fire information of flammable materials to the elevator control module;

[0078] The elevator control module is used to determine, based on the information obtained from the information acquisition module regarding the presence of flammable materials inside the elevator, whether the placement of the flammable materials is within a target placement location; wherein the target placement location corresponds to a fire emergency isolation device; if the placement of the flammable materials is within the target placement location, the module controls the elevator to operate; if, during the operation of the elevator, fire information regarding the flammable materials is obtained from the information acquisition module, the module controls the fire emergency isolation device to isolate the flammable materials.

[0079] A fire emergency isolation device is used to isolate the flammable materials.

[0080] In practical applications, the fire emergency isolation device includes a floor movable module, a support module, and a fire extinguishing module; the floor movable module includes several movable base plates that can extend and retract; the support module is located below the elevator car and is used to support the flammable materials; the fire extinguishing module is used to extinguish the fire on the isolated flammable materials.

[0081] The supporting module can be a flame-retardant protective net, which is installed below the elevator car and connected to the outer wall of the elevator car. When flammable items fall through the hollow area, it is used to catch the flammable items.

[0082] Reference Figure 3 and Figure 4 Assuming that C, F, and I in the diagram are all movable base plates, and A, D, G, B, E, and H are all fixed base plates, the combined area of ​​C, F, and I is the movable floor module, and therefore this combined area is set as the target placement position. For ease of understanding, C, F, and I are referred to as movable base plate C, movable base plate F, and movable base plate I, and B, E, and H are referred to as fixed base plate B, fixed base plate E, and fixed base plate H.

[0083] In some embodiments, refer to Figure 3 The movable base plate C is connected to the fixed base plate B via a telescopic component 1, allowing the movable base plate C to move towards the side of the fixed base plate B; the movable base plate F is connected to the fixed base plate E via a telescopic component 1, allowing the movable base plate F to move towards the side of the fixed base plate E; the movable base plate I is connected to the fixed base plate H via a telescopic component 1, allowing the movable base plate I to move towards the side of the fixed base plate H. If a fire occurs involving flammable materials inside the elevator, the control terminal controls the telescopic component 1 to extend or retract, causing the movable base plates C, F, and I to all extend or retract. This creates a hollowed-out area where the flammable materials fall under gravity into the load-bearing module below the elevator car, where the fire is then extinguished by the fire-extinguishing module.

[0084] Among them, the telescopic component 1 can be an existing device such as an electric telescopic rod or an electric cylinder.

[0085] In other embodiments, reference is made to Figure 4 The movable base plate C, which is not connected to the fixed base plate B, has electric connecting parts 2 on its three other sides. The side connected to the fixed base plate B is hinged, so that the three sides of the movable base plate C are electrically connected to their respective adjacent components. The movable base plate F, which is not connected to the fixed base plate E, has electric connecting parts 2 on its three other sides. The side connected to the fixed base plate E is hinged, so that the three sides of the movable base plate F are electrically connected to their respective adjacent components. The movable base plate I, which is not connected to the fixed base plate H, has electric connecting parts 2 on its three other sides. The side connected to the fixed base plate H is hinged, so that the three sides of the movable base plate I are electrically connected to their respective adjacent components. If a fire occurs in the flammable materials inside the elevator, the control terminal will close all the aforementioned electric connectors 2, causing the three sides of the movable base plate C, movable base plate F, and movable base plate I to be unconnected and to flip downwards towards the elevator car. That is, the combined area of ​​the movable base plate C, movable base plate F, and movable base plate I becomes hollow. At this time, the flammable materials fall into the supporting module below the elevator car under the action of gravity, and then the fire extinguishing module extinguishes the fire.

[0086] Among them, the electric connector 2 can be a structure composed of an electric telescopic rod and a latch. By extending and retracting the electric telescopic rod, it connects and disconnects from the latch, so that the three sides of the movable base plate C, movable base plate F and movable base plate I can be electrically connected and disconnected from their respective adjacent components.

[0087] It should be noted that the fire extinguishing module can use a dry powder fire extinguisher. Dry powder extinguishers are filled with dry, free-flowing fine powder, made from inorganic salts with fire-extinguishing properties and a small amount of additives, which are dried, pulverized, and mixed. Compressed carbon dioxide or nitrogen is used as a propellant to spray the dry powder extinguishing agent out to extinguish the fire. The fire extinguishing module is installed inside the elevator, with the nozzle facing the target location. When a fire occurs involving flammable materials, the control terminal activates the fire extinguisher, which then extinguishes the fire.

[0088] In practical applications, the fire emergency isolation device also includes a protective module 3, which is used to form a protective layer between the passenger and the flammable materials.

[0089] It should be noted that the protective module 3 is located between the target placement position and the passenger standing position. It can be at the connection between the target placement position and the passenger standing position, or it can be located near the passenger standing position. The protective module 3 includes an electric lifting device and a protective membrane. The protective membrane is connected to the electric lifting device. When the electric lifting device moves upward, it pulls one end of the protective membrane upward, so that the protective membrane is in an unfolded state, forming a protective layer between the passenger and the flammable items.

[0090] It should be noted that the electric lifting device uses existing equipment; as long as it can move the protective film up and down, it will not be elaborated on here. The protective film is made of fire-retardant membrane, which can provide good flame-retardant and heat-insulating effects.

[0091] In addition, a sensing device can be installed on the protection module 3. When a passenger enters the elevator and during the elevator operation, the sensing device will detect whether there is an obstruction on the protection module 3. If an obstruction is detected, the sensing device will send the obstruction information to the control terminal. The control terminal will receive the obstruction information and control the voice prompt module to prompt the passenger to remove the obstruction on the protection module 3.

[0092] In practical applications, elevators are also equipped with manual emergency escape buttons. When flammable materials begin to burn, the image recognition device and smoke detector may not have detected the fire yet. When passengers discover the fire, they can press the manual emergency escape button, which sends the emergency escape information to the control terminal. The control terminal receives the information, activates the fire emergency isolation device to isolate the flammable materials, and stops the elevator at the nearest floor, allowing passengers to escape the elevator car as quickly as possible and achieve emergency escape.

[0093] It should be noted that the manual safety button is located in a position that is not easily accessible to children, in order to prevent children from accidentally pressing it.

[0094] Compared with existing technologies, this application applies a safe elevator control method to a control terminal. When the elevator control module obtains elevator information about flammable items from the information acquisition module, it determines whether the flammable items are placed within a target location, which corresponds to a fire emergency isolation device. If the flammable items are within the target location, the elevator is controlled to operate. If, during elevator operation, fire information about the flammable items is obtained from the information acquisition module, the fire emergency isolation device is controlled to isolate the flammable items. In other words, this application, through strict control of flammable item identification and placement, ensures that flammable items are placed within the target location corresponding to the fire emergency isolation device. This allows the fire emergency isolation device to isolate the flammable items within the target location in the event of a fire or other fire accident while flammable items are in the elevator, thus ensuring the safety of passengers in the elevator.

[0095] It should be noted that each module in the flammable materials safety elevator control system in this embodiment corresponds one-to-one with each step in the flammable materials safety elevator control method in the aforementioned embodiment. Therefore, the specific implementation method and the technical effects achieved in this embodiment can be referred to the implementation method of the aforementioned flammable materials safety elevator control method, and will not be repeated here.

[0096] However, in one embodiment, the connection relationship of each module in the above-mentioned flammable materials safety elevator control system can be as follows: Figure 5 As shown.

[0097] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
