Description

Technical Field

[0001] The invention relates to the technical field of fire alarm control systems, in particular to a control system and a theft-proof door based on fire alarms. Background Art

[0002] As described in the public document CN2835474Y, the existing anti-theft doors have achieved excellent anti-theft effects. However, the excellent anti-theft effects may also have disadvantageous usage situations. For example, when a fire occurs in a house, due to the excellent anti-theft effects, the surrounding neighbors cannot enter the house to rescue in the first time, and after the firefighters arrive, they can only dismantle the house violently, which greatly prolongs the rescue time.

[0003] When smart locks are installed on anti-theft doors, the smart locks mainly use face, fingerprint, password and remote control to open the door locks. When a fire occurs in the house, the existing smart locks cannot effectively alarm. When the user does not unlock the door remotely, the door locks cannot be opened automatically, so that people outside the house cannot enter the house for rescue. Summary of the invention

[0004] Since the security door has excellent anti-pry effect, when a fire occurs in the house, people outside the house cannot enter the house for rescue immediately.

[0005] The present invention aims at the deficiencies in the prior art and provides a control system and a theft-proof door based on fire alarm.

[0006] In order to solve the above technical problems, the present invention is solved through the following technical solutions: a control system based on fire alarm, including a temperature sensing unit, a camera unit, a networking unit and a central control unit. The temperature sensing unit is used to identify temperature changes in the room. After reaching the set temperature, the camera unit is automatically started to shoot the situation in the room and transmit it to the central control unit. The central control unit identifies smoke or fire in the image, that is, confirms that a fire has occurred. The central control unit controls the networking unit to send signals and / or pictures to the user to remind the user or facilitate the user to promptly report the incident. If the user does not send feedback information or check the information for a long time, the alarm will be automatically sounded or a sound alarm will be issued.

[0007] The beneficial effect is that when a fire occurs in the house, the control system can identify it in the first time and send the fire information to the user, so that the user can know it in the first time and take effective measures. If there is no feedback for a long time, it will automatically alarm and control the door lock to open, so that outsiders can enter for rescue.

[0008] In the above scheme, preferably, the control system also includes a smart lock body. After the central control unit confirms that a fire has occurred, it controls the smart lock body to retract and then unlock it.

[0009] In the above scheme, preferably, it also includes a stop unit for limiting the door body. After confirming that a fire has occurred, the central control unit can control the stop unit to retract, thereby releasing the limit on the door body, and the door body can be opened inside and outside.

[0010] In the above scheme, preferably, it also includes an emergency trigger unit, which is a mechanical structure. When the electric control fails and the room temperature reaches the set temperature, the emergency trigger unit can pull the stop unit back to release the limit on the door body, and the door body can be opened inside and outside.

[0011] The anti-theft door with a fire alarm control system includes a door frame and a door body. The stop unit and the emergency trigger unit are both arranged on the door frame. The temperature sensing unit, the camera unit, the networking unit and the central control unit are arranged on the door body. The door body is rotatably connected to the door frame, the door body can be opened inside or outside, the stop unit can be retracted into the door frame, the smart lock body includes a lock tongue, and the lock hole for locking the door with the lock tongue is arranged on the stop unit. When a fire occurs, the emergency trigger unit controls the stop unit to be retracted into the door frame, the steering limit of the door body is released, and the lock tongue limit is released at the same time, and the door body can be pushed inward.

[0012] The beneficial effect is that after a fire occurs in the house, when the temperature reaches the set temperature, the door limit is released and can be opened inward or outward, and the lock hole position is also moved synchronously. Even if the smart lock body is not opened, the door body can be opened inward or outward. Even if the door body and the door frame are stuck, internal or external personnel can directly push the door open to escape or enter for rescue, thereby improving the safety of the anti-theft door.

[0013] In the above scheme, preferably, the stop unit includes a stop block elastically limited and slidably arranged on the door frame, a sliding groove is opened on the frame wall of the door frame, the stop block extends into the door frame through the sliding groove to block the door body, and an elastic limiting member is also arranged above the stop block to be used for the stop block to elastically restore and retract into the door frame.

[0014] In the above scheme, preferably, the emergency trigger unit includes a temperature touch unit, a pulling amplification unit and a second locking piece. The pulling amplification unit is connected to the elastic limiting piece. The second locking piece is used to lock the pulling amplification unit. The temperature touch unit is arranged on the inner door frame. The high temperature of the temperature touch unit can pull the second locking piece to unlock, and the elastic limiting piece is retracted by pulling the pulling amplification unit.

[0015] In the above scheme, preferably, the pulling amplification unit includes a support frame, a sliding block and a total pull rope, the support frame is arranged in the door frame, the sliding block is elastically slidably arranged on the guide column of the support frame, one end of the total pull rope is connected to the sliding block, and the other end is connected to the first locking piece and the elastic limit piece.

The rear end of the second locking piece is also connected to one end of the second pull rope, and the other end of the second pull rope is connected to the electric reel, and the electric reel is controlled by the central control unit.

[0017] Its beneficial effect is that when the control system can still operate normally, the door body can be unlocked and the steering limit of the door body can be released through the electric control. When the electric control system cannot operate normally due to the fire, the door body can be unlocked and the steering limit of the door body can be released through the mechanical emergency trigger unit, thereby improving the safety of the door. In the above scheme, preferably, stop units are provided on the four sides of the door frame for limiting the door body, and a lock hole is provided on the stop block of the stop unit cooperating with the lock tongue. After the stop block is retracted, the lock hole is also retracted together, and the limitation of the door frame on the lock tongue is released.

[0018] The beneficial effects of the present invention are as follows: the present invention provides a control system and an anti-theft door based on fire alarm.

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Example

[0029] See also Figure 1-Figure 8 A control system and an anti-theft door based on fire alarm include a door frame 1 and a door body 2. An intelligent lock body 21, a temperature sensing unit, a camera unit, a networking unit and a central control unit are arranged on the door body 2. The temperature sensing unit includes a temperature-sensitive sensor, which can identify changes in ambient temperature and transmit them to the central control unit. The camera unit can record the indoor situation by video. The temperature sensing unit and the camera unit transmit the extracted information to the central control unit, which analyzes it.

[0030] When the temperature rises rapidly or reaches the set temperature, the central control unit controls the camera unit to turn on and take real-time video of the indoor environment. The central control unit conducts real-time analysis and confirms that a fire has occurred in the house after identifying the source of fire or thick smoke in the graphics.

[0031] The smart lock body 21 includes a lock tongue 211, which is used to lock the door body on the door frame 1. The networking unit includes a communication module and a buzzing module. After the central control unit analyzes that a fire occurs in the house, the central control unit automatically sends a fire signal and / or a picture of the house to the resident's mobile terminal through the communication module, so that the resident knows about the fire in the house at the first time, and then sounds an alarm and / or controls the activation of the buzzing module to call for help.

[0032] If the resident does not provide feedback or check the information within the set time, the fire alarm will be automatically dialed to sound a fire alarm. The buzzing module includes a buzzer. After the central control unit analyzes the fire, the buzzing module starts to emit a buzzing sound to send a rescue message to the surrounding neighbors.

[0033] At the same time, the central control unit automatically retracts the lock tongue 211 into the smart lock body 21, so that the lock between the lock tongue 211 and the door frame 1 is released, and then the door body 2 is in an unlocked state, and people outside the house can enter the house for rescue activities.

[0034] Since the intelligent lock body 21 is controlled by electric control, after the fire spreads rapidly, the electric control will be in an unstable state and easily damaged or interfered with. At the same time, the door body 1 is easily expanded and stuck with the door frame 1 due to high temperature. The anti-theft door can only be opened in one direction under normal conditions, and the pulling force of the personnel is small, so the following situations may occur: The security door can only be opened inwards. After a fire occurs, since the door body 1 and the door frame 1 are stuck, the people inside the house cannot open the security door, nor can they push it open outwards, making it impossible to escape.

[0035] The security door can only be opened outwards, which means that rescue workers outside the house cannot pull the security door open outwards immediately, nor can they push it open inwards, making it impossible for them to enter the house for rescue.

[0036] The anti-theft door also includes a stop unit 3 and an emergency trigger unit 4, and the door body 2 includes a first door body 22 and a second door body 23. One side of the first door body 22 is connected to one side of the door frame 1 by a hinge. Under the action of the hinge, the first door body 22 can rotate toward the inside of the house without obstruction, but cannot rotate outward. The other side of the first door body 22 is connected to one side of the second door body 23 by a hinge. Under the action of the hinge, the second door body 23 can rotate toward the outside of the house, but cannot rotate inward. A first locking piece 24 is elastically limited and slidingly arranged on the upper and lower end surfaces of the first door body 22, and a limiting hole is opened at a corresponding position of the door frame 1. The first locking piece 24 is used to lock the first door body 22 and the door frame 1 in the initial state so that it does not rotate, and only the second door body 23 can be opened outward.

[0037] The stop unit 3 includes a stop block 31, an elastic limiting member 32 and a fixed plate 33. The fixed plate 33 is fixedly set in a C-shaped groove connecting the door frame 1 and the wall. The stop block 31 is elastically limited and slidably set on the fixed plate 33 through a plurality of guide columns. At the same time, a sliding groove 11 is opened on the frame wall of the door frame 1. The stop block 31 slides downward to compress the elastic member and enters the sliding groove 11 at the same time, so that the lower end of the stop block 31 enters the frame to limit the door body 2. The elastic limiting member 32 is fixedly set in the C-shaped groove connecting the door frame 1 and the wall.

[0038] The elastic expansion head 321 of the elastic limiting member 32 is located between the fixed plate 33 and the stop block 31 in the initial position, and is used to limit the stop block 31 from rebounding upward and retracting into the door frame 1. When the elastic expansion head 321 retracts backward into the elastic limiting member 32, the restriction above the stop block 31 disappears, so it slides upward and retracts into the door frame 1 under the action of the elastic force, and then the restriction on the inward rotation of the door body 2 disappears.

[0039] The door frame 1 is provided with sliding grooves 11 on the four-way frame walls, and stop units 3 are provided in the C-shaped grooves connected to the walls in four directions, so that the door body 2 is limited to rotate inward in four directions, and on the stop block 31 corresponding to the lock tongue 211, a lock hole block is provided at a position corresponding to the tongue lock 211, and a lock hole 311 is provided on the lock hole block, and the sliding groove 11 here is adapted to the lock hole block. After the stop block 31 is retracted into the door frame 1, the lock hole block is also retracted together to release the lock of the lock tongue 211. At this time, the door body 2 rotates, and the tongue lock 211 will not contact the door frame 1 in the extended state.

[0040] The emergency trigger unit 4 includes a temperature touch unit, a pull amplification unit 42 and a second locking member 43. The temperature touch unit includes a bimetallic strip. The temperature control unit is arranged on the side of the door frame 1 facing the interior of the house. When the indoor temperature rises to the deformation temperature of the bimetallic strip, the bimetallic strip automatically deforms. The pull amplification unit 42 includes a support frame 421, a sliding block 422 and a main pull rope 423. The support frame 421 is arranged in a C-shaped groove connecting the door frame 1 and the wall. The support frame 421 is provided with a guide column and a sliding guide groove. The sliding block 422 is arranged on the guide column and the sliding guide groove for guiding sliding. The guide column is provided with a first An elastic member 424, the two ends of the first elastic member 424 respectively touch the sliding block 422 and the end plate of the support frame 421, a locking hole 4221 is opened on the side wall of the sliding block 422, the second locking member 43 is an elastic telescopic rod, which is fixedly set on the support frame 421, and the rear end of the second locking member 43 is also connected to one end of the second pull rope, and the other end of the second pull rope is connected to the electric reel, and the electric reel is controlled by the central control unit, and the sliding block 422 is connected to one end of the main pull rope 423, and the other end is connected to the first locking member 24 and the elastic telescopic head 321 of all the elastic limit members 32.

[0041] In the initial state, the front end of the telescopic rod of the second locking member 43 is inserted into the locking hole 4221 of the sliding block 422, thereby locking the sliding block 422. At this time, the first elastic member 424 is in a compressed state. After a fire occurs, the central control unit first controls the electric reel to rotate through the electronic control to pull the second locking member 43 out of the locking hole 4221, unlocking the sliding block 422, so that the sliding block 422 slides forward under the action of the first elastic member 424. When the sliding block 422 is unlocked and slides forward, the first locking member 43 is pulled by the main pull rope 423. 24 and the elastic telescopic head 321 are retracted, and the first locking piece 24 is retracted to unlock the first door body 22. The elastic telescopic head 321 is retracted to release the limit of the stop block 31, and then it is automatically retracted into the door frame 1 under the action of the elastic force. At the same time, the lock hole 311 is also retracted, so that the door body 2 is in an unlocked state and can be rotated inward or outward. At this time, even if the door body 2 is stuck with the door frame 1 due to thermal expansion, the person outside the door can easily open the door by hitting it inward, thereby removing the limitation that the anti-theft door can only be opened in one direction, so that the rescue personnel outside can quickly open the anti-theft door.

[0042] When the temperature in the room reaches the deformation temperature of the bimetallic strip, the bimetallic strip is deformed, and one end of the first pull rope 411 is connected to the deformed end of the bimetallic strip, and the other end is connected to the rear end of the second locking member 43. Then, the telescopic rod of the second locking member 43 is pulled away from the locking hole 4221 by the first pull rope 411, so that the sliding block 422 slides forward under the action of the first elastic member 424, thereby mechanically releasing the steering limit of the anti-theft door and the lock with the door frame.

[0043] The deformation temperature of the bimetallic strip is higher than the temperature set by the temperature sensing unit, so the electronic control is first unlocked. After the temperature continues to rise to the deformation temperature of the bimetallic strip, the mechanical unlocking is performed. Therefore, even if the electronic control is interfered with by the high temperature and cannot work normally, the mechanical unlocking can release the steering limit of the anti-theft door and the lock with the door frame.

[0044] The door frame 2 is also provided with a spray device 5, which includes a rotating bracket 51. A rotating groove is provided on the upper wall on the inner side of the door frame 2. One end of the rotating bracket 51 is rotatably provided in a C-shaped groove of the door frame 2 connected to the wall, and a torsion spring is sleeved on the rotating shaft. One end of the torsion spring is limited on the door frame 2, and the other end is limited on the rotating bracket 51. A spray head is provided on the rotating bracket 51. After the anti-theft door is installed, the spray head is connected to the water supply pipe in the house through a hose. A pin hole is provided on the other end of the rotating bracket 51, and a third elastic telescopic rod is provided in the C-shaped groove of the door frame 2 above the pin hole for locking the rotating bracket 51.

[0045] In the initial state, the rotating bracket 51 is hidden in the door frame 2, and the torsion spring is in the elastic knob state, and the third elastic telescopic rod is also connected to the main pull rope 423. Therefore, after the sliding block 422 is unlocked, the lock of the rotating bracket 51 is also released synchronously, so that the rotating bracket 51 rotates about 90 degrees under the action of the torsion spring.

[0046] The sprinkler head is a fire sprinkler head. The glass tube will burst at high temperature, and the bursting temperature is higher than the deformation temperature of the bimetallic strip. Therefore, after the rotating bracket 51 is opened, the temperature in the room continues to rise, and then the glass tube of the sprinkler head bursts, and water sprays out from the sprinkler head, wetting the rescue personnel, increasing the safety of the rescue personnel, and at the same time cooling the anti-theft door to reduce the phenomenon of the door body 2 being stuck due to thermal expansion.

[0047] Its working principle or usage is as follows: In the initial state, the first door body 22 is locked, and the stop unit 3 extends out of the frame wall of the door frame 1 to limit the door body 2, so that the door body 2 can only be opened in one direction.

[0048] After a fire is discovered in the house, the central control unit first pulls the second locking piece 43 to unlock it. After the temperature continues to rise, the bimetallic strip is deformed and the second locking piece 43 is mechanically pulled to unlock it. The double unlocking mechanism ensures that the second locking piece 43 is successfully unlocked. After the second locking piece 43 is unlocked, the sliding block 422 slides forward under the action of the first elastic piece 424, and the first locking piece 24 and the elastic telescopic head 321 are retracted by pulling the total pull rope 423.

[0049] After the first locking piece 24 is retracted, the first door body 22 is unlocked, and the elastic telescopic head 321 is retracted to release the limit of the stop block 31, and then it is automatically retracted into the door frame 1 under the action of elastic force. At the same time, the lock hole 311 is also retracted, so that the door body 2 is in an unlocked state and can rotate inward or outward. At this time, even if the door body 2 is stuck with the door frame 1 due to thermal expansion, the person outside the door can easily open the door by hitting it inward, which removes the limitation that the anti-theft door can only be opened in one direction, so that the rescue personnel outside can quickly open the anti-theft door.

[0050] At the same time, the sliding block 422 unlocks the rotating bracket 51, so that the rotating bracket 51 rotates about 90 degrees under the action of the torsion spring, and water is sprayed outward from the sprinkler head to wet the rescuers, thereby increasing the safety of the rescuers and cooling the anti-theft door at the same time, reducing the phenomenon of the door body 2 being stuck due to thermal expansion. Example

[0051] See also Figure 1-Figure 7 and Fig. 9 The difference between the second embodiment and the first embodiment is that the door body 2 is a single entity, the door frame 1 and the door body 2 are connected by a two-way hinge, or a free-rotating shaft is installed on the upper and lower end surfaces of one side of the door body 2, and is rotatably connected to the door frame 1 through the free-rotating shaft, and the rest are the same.

[0052] In this embodiment, the door frame 1 and the door body 2 are connected by a two-way hinge, or a free-rotating shaft is installed on the upper and lower end surfaces of one side of the door body 2, and is rotatably connected to the door frame 1 through the free-rotating shaft. In the initial state, the stop unit 3 limits the opening of the door body 2 inward or outward, so that the door body 2 can only be opened to one side. After a fire occurs, the stop unit 3 retracts into the door frame 1, and the door body 2 can be opened inward or outward.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
