Technical Field

[0001] The present invention belongs to the field of Internet of Things, and particularly relates to an intelligent emergency self-rescue and escape device for Internet of Things and an operation method thereof. Background Art

[0002] All kinds of disaster accidents, large and small, occur around us every year. Especially with the high-speed development of urbanization and the row upon row of high-rise buildings, the possibility of accidental disasters in high-rise buildings also increases (such as fires, earthquakes, gas leaks, collapses, explosions or terrorist attacks, etc.). Accidental disasters threaten people's lives and property safety all the time!

[0003] At present, with the increasing popularity of Internet, Internet of Things and artificial intelligence, the rescue work for accidental disasters in high-rise buildings faces many challenges. Existing emergency rescue equipment generally has the problems of large volume and poor mobility. Taking a high-rise building fire as an example, due to the limitations of complex terrain and environmental obstacles, traditional rescue equipment is often difficult to be quickly deployed in an emergency, unable to implement rescue in a timely and effective manner, resulting in a waste of precious rescue time and increasing the risk of casualties and property losses. Therefore, it is of great practical significance to develop an intelligent emergency self-rescue and escape device with a compact structure and convenient operation. Summary of the Invention

[0004] Aiming at the defects existing in the prior art, the purpose of the present invention is to provide an intelligent emergency self-rescue and escape device with a compact structure and convenient operation, which realizes rapid window opening and safe slow descent through an electric push rod and a friction type speed reduction mechanism.

[0005] The purpose of the present invention is achieved by the following technical solutions: An intelligent emergency self-rescue and escape device, characterized in that it includes: an emergency self-rescue and escape window, which consists of a window frame fixed to a wall, an outwardly pushable movable window sash, a fixed end of a rotating shaft, a movable end of a rotating shaft, and an electric push rod; one end of the electric push rod is fixed to the window frame, and the other end is connected to the movable window sash, and a rotating motor drives a gear speed reduction mechanism to convert rotational motion into linear reciprocating motion. The electric push rod is internally provided with an angle detection device for real-time monitoring of the opening and closing angle of the window sash; an escape slow descent group, including an escape slow descent device box, a wire rope reel, a friction type speed reduction mechanism and a wearing sling; the friction type speed reduction mechanism includes a planetary gear reducer and friction blocks, and controls the slow descent speed through friction. The friction blocks of the friction type speed reduction mechanism adjust the pressure through solenoid valves to realize dynamic control of the slow descent speed; an intelligent control group for controlling the start of the electric push rod and the escape slow descent group. The intelligent control group includes wifi, Bluetooth wireless modules and manual switches.

[0006] Both inside and outside the emergency escape device box are provided with outward-opening doors, and electromagnetic locks are installed on the outward-opening doors. The electromagnetic locks are composed of lock bodies, coils, chips, and auxiliary components such as U-shaped buckles, screws, and brackets, and the locking or opening of the outward-opening doors is achieved by controlling the energization or de-energization of the coils.

[0007] The intelligent control group includes a main PCB panel, which integrates a CPU chip, a database storage module, a sending module, a receiving module, a wifi, a Bluetooth wireless module, a power supply module, a driving machine module, and a sensor module. The main PCB panel is electrically connected to the electromechanical devices that control the emergency self-rescue escape window and the emergency escape group, as well as the intelligent alarm and security equipment, and remotely interacts with the APP installed on the intelligent terminal device through the Internet.

[0008] The intelligent alarm and security equipment includes an infrared monitoring camera, an emergency alarm button, a vibration sensor, a temperature sensor, and a gas sensor device, which are used to monitor the situation in a specific area in real time, detect abnormal situations such as earthquakes, fires, chemical substances, or concentration changes. When an illegal intrusion or an emergency is detected, the control host starts the alarm system.

[0009] The power supply module includes an external power supply, a backup power supply, and a power supply switching device. The external power supply is connected to the commercial power through a power adapter, and the backup power supply is an internal battery, which supplies power to the control circuit, detection circuit, and alarm circuit of the intelligent control group.

[0022] The present invention will be further described in detail below with reference to the drawings and embodiments:

[0023] See Figure 1 and 2 As shown, in this embodiment, an intelligent emergency self-rescue and escape device 1 includes an emergency self-rescue and escape window 10, an escape descending group 20, and an intelligent control group 30;

[0024] See Figure 1 and 2, as shown in FIGS. 3, the emergency self - rescue escape window 10 is composed of a window frame 101 fixed to the wall, an outward - pushable movable window sash 102, a fixed end 103a and a movable end 103b of a rotating shaft installed between the main window frame 101 and the outward - pushable movable window sash 102, and a push - pull movable electric push rod 104, and is connected to an intelligent control group 30. One end of the electric push rod 104 is fixed at the left and right corners of the upper window frame 101 by a base 1041. It also includes a rotating motor, a connecting gear speed - changing mechanism, a connecting push - pull lifting screw rod, a connecting push - rod joint shaft end, and is movably connected to the left and right corners of the window sash 102. The rotating motor is connected to a synchronous control switch and a power supply. The push - pull lifting screw rod can convert the rotary motion of the motor into a linear reciprocating up - and - down motion of the push rod, driving the movable window sash 102 to achieve the purpose of retracting and lifting through the fixed end 1042a of the movable hinge shaft and the movable end 103b of the hinge shaft. Usually, when the window sash 102 is closed with the window frame 101, it is no different from other windows of the same type. Once an accidental disaster occurs and people need to escape, the electric push rod 104 can be started by remote control or manual switch through the intelligent control group 30. An angle detection device 1041 is installed inside the electric push rod 104 to monitor the opening and closing angle of the outward - pushable movable window sash 102 in real time, and the window sash 102 can be pushed open to a position where it forms a 90 - degree angle with the window frame 101, forming an emergency self - rescue escape exit platform; in an emergency, the user sends an instruction through the mobile phone APP. After the wireless module receives the signal, the electric push rod 104 is started. The angle detection device 1041 built in the push rod can ensure that the window sash is opened to 90 degrees; in the manual mode, the user presses the emergency switch, and the system sequentially executes the window - opening and slow - descent operations according to the preset program.

[0025] See Figure 3 , 4 , as shown in FIGS., the emergency escape slow - descent group 20 is composed of an emergency escape slow - descent device box 201 fixed to the wall. Outer opening doors 2011 are provided both inside and outside the emergency escape slow - descent device box 201. An electromagnetic lock 2012 is installed on the outer opening door 2011, which is composed of a lock body, a coil, and a chip, and includes auxiliary components such as a U - shaped buckle, screws, and brackets. When the coil is energized, it generates a magnetic force to attract the lock body, thus locking the door. When the power supply is cut off, the lock body also opens, and it can be remotely controlled or manually opened and closed; a wire rope reel 202 is fixedly installed inside the box. A wire rope 2021 is wound around the wire rope reel 202. The terminal of the wire rope 2021 is connected to a hook 203. The hook 203 is used for hook - type movable connection with a sling 205. A friction - type speed - reducing mechanism 204 is installed on the side of the wire rope reel 202.

[0026] The friction block of the friction type deceleration mechanism 204 adjusts the pressure through the electromagnetic valve to realize the dynamic control of the slow-down speed; when working, the planetary gear deceleration mechanism in the main engine is driven to operate through the slow-down rope to generate friction with the friction block in the friction wheel hub to ensure that the user safely descends to the ground; the wearing sling 205 is worn on the waist and two thighs, and the wearing sling 205 has an adjusting buckle 2051 to adjust the tightness, so that the person can hang and slowly descend along the rope. The safety rescue device is installed on the window and usually placed in the escape slow-down device box 201. In case of emergency, it can rescue the victims in high-rise buildings. When people are trapped in high-rise buildings, the escape slow-down box 201 can be opened remotely or manually, and at the same time, the emergency self-rescue escape window 10 is opened, and the wearing sling 205 is put on to use the device of the escape slow-down group 20 to slowly descend and escape to the ground;

[0027] For example, Example 1:

[0028] When the user triggers the intelligent control group, the system will perform the window opening and slow descent operations in sequence according to the preset program; after the user puts on the harness, the escape slow descent group is started, and the friction deceleration mechanism adjusts the speed to a safe range through the friction block.

[0029] Embodiment 2:

[0030] When in manual mode, the user presses the emergency switch, and the system performs the window opening and slow descent operations in sequence according to the preset program; after the user puts on the harness, the escape slow descent group is started, and the friction deceleration mechanism adjusts the speed to a safe range through the friction block.

[0031] See also Figure 4 , 5 As shown, the intelligent control group 30 is a circuit board integrated by a main PCB panel 301 (including a CPU chip, a database storage module, a sending module, a receiving module, a wifi, a Bluetooth wireless module, a power supply module, a driver module, and a sensor module);

[0032] The main PCB panel 301 is electrically connected to control the electromechanical equipment of the emergency self-rescue escape window 10, the escape slow-down group 20, and the intelligent alarm security equipment 302, and remotely communicates and interacts with the site through the Internet and the APP installed on the intelligent terminal device. The intelligent terminal device can be a mobile phone, a computer or a tablet, etc.;

[0033] The intelligent alarm security equipment 302 also includes infrared monitoring cameras, emergency alarm buttons, vibration, temperature, gas sensors, etc., which are responsible for real-time monitoring of specific areas and detecting earthquakes, fires, abnormal changes in chemical substances or concentrations. Once illegal intrusion or emergency situations are detected, the control host will activate the alarm system to achieve all-round security protection and ensure the safety of personnel.

[0034] The power supply further includes an external power supply, a backup power supply, and a power switching device; it is a DC power supply that can be externally connected to household appliances or rechargeable batteries. The external power supply is connected to the mains through a power adapter. The backup power supply is an internal battery that can convert electrical energy into current and deliver the current to the devices that need it, and can supply power to the control circuit, detection circuit, and alarm circuit of the intelligent control group 30. The rotary motor of the electric push rod 104 is powered by the power supply to control the rotation speed of the drive wheel main shaft. The sensor module connects the instructions, drives, and controls the signals of the security equipment within the main control module. When an accidental disaster occurs and rescue and evacuation are needed, through the intelligent control group 30, the control circuit can notify the user of the signal, and the user can receive the signal from the APP on the intelligent terminal device to remotely communicate and interact with the scene and control the outer door 2011 provided inside and outside the escape and rescue device box 201.

[0035] The intelligent emergency self-rescue and escape method according to the above-described device includes the following steps:

[0036] S1 Receive an escape instruction through the intelligent control group 30;

[0037] S2 Start the electric push rod 104 to push the movable window sash 102 open to 90 degrees;

[0038] S3 Start the escape and rescue group 20 to connect the harness 205 to the human body;

[0039] S4 Control the descent speed through the friction type speed reduction mechanism 204 to achieve a safe descent.
