Description

Technical Field

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

[0002] As described in the published document CN2835474Y, the existing anti-theft doors have achieved excellent anti-theft effects. However, excellent anti-theft effects may also have adverse usage situations. For example, when a fire breaks out in a house, due to the excellent anti-theft effect, neighbors cannot enter for rescue in the first place, and after the fire department arrives, they can only conduct violent dismantling, greatly prolonging the rescue time.

[0003] When installing an intelligent lock on an anti-theft door, the intelligent lock mainly functions to unlock the door through face recognition, fingerprint recognition, password input, and remote control. However, when a fire breaks out inside the house, the existing intelligent locks cannot effectively give an alarm, and when the user does not remotely unlock the door, the door lock cannot be automatically opened, so that people outside the house cannot enter the house for rescue. Summary of the Invention

[0004] Due to the excellent anti-prying effect of the anti-theft door, when a fire breaks out inside the house, people outside the house cannot enter the house for rescue in the first place.

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

[0006] To solve the above technical problems, the present invention is solved by the following technical solutions: A control system based on fire alarms includes a temperature sensing unit, a camera unit, a networking unit, and a central control unit. The temperature sensing unit is used to identify changes in the indoor temperature. After reaching the set temperature, it automatically activates the camera unit to capture the indoor situation and transmits 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 images to the user to remind the user or facilitate the user to call the police in time. If the user does not send feedback information or view the information for a long time, it will automatically call the police or sound an alarm.

[0007] The beneficial effects are that when a fire breaks out inside the house, the control system can identify it in the first place and send the fire information to the user, enabling the user to know in the first place and take effective measures. If there is no feedback for a long time, it will automatically call the police and at the same time control the door lock to open, facilitating external personnel to enter for rescue.

[0008] In the above solution, preferably, the control system further includes an intelligent lock body. After the central control unit confirms that a fire has occurred, it controls the intelligent lock body to retract and then unlocks.

[0009] In the above solution, preferably, it further includes a stop unit for limiting the door body. After the central control unit confirms a fire, it can control the stop unit to retract, thereby releasing the limit on the door body, and the door body can be opened inward and outward.

[0010] In the above solution, preferably, it further includes an emergency trigger unit. The emergency trigger unit is of a mechanical structure. When the electronic control fails and the room temperature reaches the set temperature, the emergency trigger unit can pull the stop unit to retract, release the limit on the door body, and the door body can be opened inward and outward.

[0011] An anti-theft door applied 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, and the door body can be opened inward or outward. The stop unit can retract into the door frame. The intelligent lock body includes a lock tongue, and a lock hole cooperating with the lock tongue to lock the door is arranged on the stop unit. When a fire occurs, the emergency trigger unit controls the stop unit to retract into the door frame, the steering limit of the door body is released, and at the same time the lock tongue limit is released, and the door body can be pushed inward.

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

[0013] In the above solution, preferably, the stop unit includes a stop block elastically and slidably arranged on the door frame. A sliding groove is formed on the frame wall of the door frame, and the stop block extends into the door frame through the sliding groove to block the door body. An elastic limiting member is further arranged above the stop block for the stop block to elastically recover and retract into the door frame.

[0014] In the above solution, preferably, the emergency trigger unit includes a temperature sensing unit, a pulling and amplifying unit and a second locking member. The pulling and amplifying unit is connected to the elastic limiting member, and the second locking member is used to lock the pulling and amplifying unit. The temperature sensing unit is arranged on the inner door frame. When the temperature sensing unit is at a high temperature, it can pull the second locking member to unlock, and pull the elastic limiting member to retract through the pulling and amplifying unit.

[0015] In the above solution, preferably, the pulling and amplifying unit includes a support frame, a sliding block and a total pulling rope. The support frame is arranged inside the door frame, the sliding block is elastically slidably arranged on the guide post of the support frame, one end of the total pulling rope is connected to the sliding block, and the other end is connected to the first locking member and the elastic limiting member.

[0016] In the above solution, preferably, the temperature-sensitive unit includes a bimetallic strip. When the temperature rises to the set temperature, it deforms automatically. One end of a first pulling rope is connected to the deformed end, and the other end is connected to a second locking member. One end of a second pulling rope is also connected to the rear end of the second locking member, and the other end of the second pulling rope is connected to an electric winch, which is controlled by a central control unit.

[0017] The beneficial effect is that when the control system can still operate normally, the door can be unlocked electrically, and the steering limit of the door can be released. When the electric control system is affected by the fire and cannot operate normally, the door can also be unlocked and the steering limit of the door can be released through a mechanical emergency trigger unit, thereby improving

[0018] In the above solution, preferably, stop units are provided on the peripheral walls of the door frame to limit the door body, and a lock hole is provided in the stop block of the stop unit that cooperates with the lock tongue. After the stop block retracts, the lock hole also retracts together, and the limit of the door frame on the lock tongue is released.

[0019] The beneficial effect of the present invention is that the present invention provides a control system and an anti-theft door based on fire alarm. When a fire breaks out in the house, the control system can unlock, alarm and release the steering limit of the door body electrically. At the same time, when the temperature in the house reaches the set temperature, the emergency trigger device can unlock and release the steering limit of the door body mechanically, ensuring that after the fire breaks out, people inside or outside can directly break open the door body to escape or enter for rescue, thereby improving the safety of the anti-theft door.

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners: Embodiment

[0030] See Figures 1-8 , a control system and an anti-theft door based on a fire alarm, including 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 the surrounding temperature change and transmit it to the central control unit. The camera unit can video-record the situation inside the house. The temperature sensing unit and the camera unit transmit the extracted information to the central control unit for analysis by the central control unit.

[0031] When the temperature rises rapidly or rises to a set temperature, the central control unit controls the camera unit to turn on and conduct real-time imaging of the indoor environment. The central control unit analyzes in real time and confirms that there is a fire in the house after identifying a fire source or thick smoke in the image.

[0032] The intelligent lock body 21 includes a lock tongue 211. The lock tongue 211 is used to lock the door body on the door frame 1. The networking unit includes a communication module and a buzzer module. After the central control unit analyzes that there is a fire in the house, the central control unit automatically sends a fire signal and / or an indoor picture to the user's mobile terminal through the communication module, so that the user can know that there is a fire in the house in the first time, and then make an alarm and / or control the buzzer module to sound for help.

[0033] If the user does not give feedback or view the information within the set time, the fire alarm phone will be automatically dialed for fire alarm. The buzzer module includes a buzzer. After the central control unit analyzes the fire situation, the buzzer module starts to emit a buzzing sound to send a rescue message to the surrounding neighbors.

[0034] At the same time, the central control unit automatically retracts the lock tongue 211 into the intelligent lock body 21, releases the locking of the tongue lock 211 and the door frame 1, and then the door body 2 is in an unlocked state, and the outdoor personnel can enter the house for rescue activities.

[0035] Since the intelligent lock body 21 is controlled electronically, after the fire spreads rapidly, the electronic control will be in an unstable state and is extremely easy to be damaged or interfered. At the same time, the door body 1 is extremely easy to expand and jam with the door frame 1 due to high temperature. And the anti-theft door can only be opened unidirectionally in the normal state, and the pulling force of the personnel is small, the following situations will occur:

[0036] The anti-theft door can only open inwards. After a fire occurs, due to the jamming of the door body 1 and the door frame 1, the indoor personnel cannot open the anti-theft door, and cannot break it open outwards, and cannot escape outwards.

[0037] The anti-theft door can only open outwards, which may cause the rescue workers outside the house to be unable to pull the anti-theft door outwards immediately, and unable to break it inwards, so they cannot enter the house for rescue.

[0038] The anti-theft door further includes a stop unit 3 and an emergency trigger unit 4. 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 through a hinge. Under the action of the hinge, the first door body 22 can rotate towards the inside of the house without obstruction and cannot rotate outwards. The other side of the first door body 22 is connected to one side of the second door body 23 through a hinge. Under the action of the hinge, the second door body 23 can rotate towards the outside of the house and cannot rotate inwards. Elastic limit slides are arranged on the upper and lower end faces of the first door body 22, and limit holes are opened at the corresponding positions on the door frame 1. In the initial state, the first door body 22 is locked with the door frame 1 by the first locking member 24 and does not rotate. Therefore, only the second door body 23 can be opened outwards.

[0039] The stop unit 3 includes a stop block 31, an elastic limit member 32 and a fixing plate 33. The fixing plate 33 is fixedly arranged in the C-shaped groove where the door frame 1 is connected to the wall. The stop block 31 is elastically limit slid on the fixing plate 33 through a plurality of guide posts. At the same time, a sliding groove 11 is opened on the frame wall of the door frame 1. The stop block 31 slides down to compress the elastic member and at the same time enters the sliding groove 11, so that the lower end of the stop block 31 enters the frame to limit the door body 2. The elastic limit member 32 is fixedly arranged in the C-shaped groove where the door frame 1 is connected to the wall.

[0040] The elastic telescopic head 321 of the elastic limit member 32 is located between the fixing plate 33 and the stop block 31 in the initial position, and is used to limit the upward rebound of the stop block 31 and retract into the door frame 1. When the elastic telescopic head 321 retracts backward into the elastic limit member 32, the restriction above the stop block 31 disappears. Therefore, under the action of the elastic force, it slides upward and retracts into the door frame 1, and then the limit on the inward rotation of the door body 2 disappears.

[0041] Sliding grooves 11 are opened on the four-direction frame walls of the door frame 1, and stop units 3 are arranged in the C-shaped grooves connected to the wall in four directions. Therefore, the inward rotation of the door body 2 is limited in four directions. On the stop block 31 corresponding to the lock tongue 211, a lock hole block is arranged at the position corresponding to the tongue lock 211. A lock hole 311 is opened on the lock hole block, and the sliding groove 11 here is adapted to the lock hole block. After the stop block 31 retracts into the door frame 1, the lock hole block also retracts together, releasing the lock on 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.

[0042] The emergency trigger unit 4 includes a temperature trigger unit, a pulling and amplifying unit 42, and a second locking member 43. The temperature trigger unit includes a bimetal sheet. The temperature control unit is arranged on the side of the door frame 1 facing the interior of the house. When the temperature inside the house rises to the deformation temperature of the bimetal sheet, the bimetal sheet deforms automatically. The pulling and amplifying unit 42 includes a support frame 421, a sliding block 422, and a main pulling rope 423. The support frame 421 is arranged in the C-shaped groove where the door frame 1 is connected to the wall. The support frame 421 is provided with guide posts and sliding guide grooves. The sliding block 422 is guided and slidably arranged on the guide posts and the sliding guide grooves. A first elastic member 424 is sleeved on the guide posts. The two ends of the first elastic member 424 respectively abut against the sliding block 422 and the end plate of the support frame 421. A locking hole 4221 is formed on the side wall of the sliding block 422. The second locking member 43 is an elastic telescopic rod, which is fixedly arranged on the support frame 421. The rear end of the second locking member 43 is also connected to one end of a second pulling rope. The other end of the second pulling rope is connected to an electric winch. The electric winch is controlled by a central control unit. One end of the main pulling rope 423 is connected to the sliding block 422, and the other end is connected to the first locking member 24 and the elastic telescopic heads 321 of all the elastic limiting members 32.

[0043] 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 breaks out, first, the central control unit controls the electric winch to rotate through electric control, pulling 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 24 and the elastic telescopic head 321 are pulled in through the main pulling rope 423. After the first locking member 24 is pulled in, the first door body 22 is unlocked. When the elastic telescopic head 321 is pulled in, the stopper 31 is released from the limit. Then, under the action of the elastic force, it automatically retracts into the door frame 1, and at the same time, the lock hole 311 also retracts together. Thus, the door body 2 is in an unlocked state and can rotate inward or outward. At this time, even if the door body 2 expands due to heat and gets stuck with the door frame 1, the people outside can easily open the door by hitting it inward forcefully, eliminating the limitation that the anti-theft door can only be opened unidirectionally, enabling the rescue personnel outside to quickly open the anti-theft door.

[0044] When the temperature inside the house reaches the deformation temperature of the bimetal sheet, at this time, the bimetal sheet deforms. One end of a first pulling rope 411 is connected to the deformed end of the bimetal sheet, 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 out of the locking hole 4221 through the first pulling 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 locking with the door frame.

[0045] The deformation temperature of the bimetallic strip is higher than the temperature set by the temperature sensing unit. Therefore, the electronic control unlocks first. After the temperature continues to rise to the deformation temperature of the bimetallic strip, mechanical unlocking is carried out. Thus, even when the electronic control is interfered by high temperature and cannot work properly, the mechanical unlocking can still release the steering limit of the anti-theft door and the locking with the door frame.

[0046] A spraying device 5 is further arranged on the door frame 2. The spraying device 5 includes a rotating bracket 51. A rotating groove is formed on the upper edge wall inside the door frame 2. One end of the rotating bracket 51 is rotatably arranged in the 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 arranged on the rotating bracket 51. After the anti-theft door is installed, the spray head is communicated with the water supply pipe in the house through a hose. A pin hole is formed at the other end of the rotating bracket 51, and a third elastic telescopic rod is arranged in the C-shaped groove of the door frame 2 above the pin hole for locking the rotating bracket 51.

[0047] In the initial state, the rotating bracket 51 is hidden inside the door frame 2. At the same time, the torsion spring is in an elastic rotation state, and the third elastic telescopic rod is also connected to the total pull rope 423. Therefore, after the sliding block 422 is unlocked, the locking 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.

[0048] The spray 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 and the temperature in the house continues to rise, the glass tube of the spray head bursts, and water sprays out from the spray head, wetting the rescue personnel entering the house, increasing the safety of the rescue personnel, and at the same time cooling the anti-theft door to reduce the phenomenon that the door body 2 is stuck due to thermal expansion.

[0049] Its working principle or usage method is as follows:

[0050] 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 unidirectionally.

[0051] After a fire is detected in the house, the central control unit first pulls the second locking member 43 to unlock it. After the temperature continues to rise, the bimetallic strip deforms, and the second locking member 43 is unlocked by mechanical pulling. The double unlocking mechanism ensures the successful unlocking of the second locking member 43. After the second locking member 43 is unlocked, the sliding block 422 slides forward under the action of the first elastic member 424, and the first locking member 24 and the elastic telescopic head 321 are pulled in through the total pull rope 423.

[0052] After the first locking member 24 retracts, the first door body 22 is unlocked. When the elastic telescopic head 321 retracts, the stopper 31 is released from the limit position. Then, under the action of the elastic force, it automatically retracts into the door frame 1. At the same time, the lock hole 311 also retracts together, so that the door body 2 is in the unlocked state and can rotate inward or outward. At this time, even if the door body 2 expands due to heat and gets stuck with the door frame 1, people outside the door can easily open the door by hitting it inward forcefully, which eliminates the limitation that the anti-theft door can only be opened unidirectionally and enables the rescue personnel outside to quickly open the anti-theft door.

[0053] 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. Water sprays out from the spray head, wetting the rescue personnel entering, increasing the safety of the rescue personnel, and at the same time cooling the anti-theft door to reduce the phenomenon that the door body 2 gets stuck due to heat expansion. Embodiment

[0054] See Figures 1-7 and Figure 9 In the second embodiment, the difference compared with the first embodiment is that the door body 2 is a single integral body, and the door frame 1 and the door body 2 are connected through a two-way hinge, or free rotating shafts are installed on the upper and lower end faces on one side of the door body 2, and the door body 2 is rotatably connected to the door frame 1 through the free rotating shafts, and the rest are the same.

[0055] In this embodiment, the door frame 1 and the door body 2 are connected through a two-way hinge, or free rotating shafts are installed on the upper and lower end faces on one side of the door body 2, and the door body 2 is rotatably connected to the door frame 1 through the free rotating shafts. 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.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. And these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
