Description

Technical Field

[0001] The present invention relates to the field of smart homes, and in particular to a smart home security system. Background Art

[0002] With the continuous improvement of living standards, people have a clearer understanding and higher requirements for indoor anti-theft. Among the existing anti-theft technologies, optical signal detection and recognition alarm anti-theft and video surveillance anti-theft are the two main methods. For optical signal detection and recognition, a common method is infrared detection. The existing anti-theft system is based on optical signal anti-theft. It mainly installs a fixed light source generation system to emit specific light. When an object blocks the light, it will trigger an alarm. This kind of home security system is a very basic anti-theft system. As long as the entrant knows the installation location in advance, for example, knowing that it is an infrared alarm, then just avoiding this infrared ray can circumvent the alarm system and successfully break into the house to steal. In order to improve the anti-theft performance, many users choose to set up multiple anti-theft devices in multiple corners, such as Figure 1 The method shown in which multiple anti-theft devices are set at intervals forms a uniform and stable infrared area, but still produces a large safety gap space. The path of the infrared setting is constant and unchanging. Even if the infrared is invisible, after knowing the specific arrangement area, it can pass safely and completely avoid the anti-theft system. Summary of the invention

[0003] The problem to be solved by the present invention is to provide an intelligent home security system in view of the above-mentioned deficiencies in the prior art, which solves the problems in the prior art that the burglar alarm signal path is constant and inconvenient, easy to circumvent, and the monitoring range cannot be freely adjusted.

[0004] To achieve the above object, the present invention provides the following technical solutions: The present invention provides an intelligent home security system, which mainly includes an alarm and an optical signal transmitter or identifier connected thereto, and an optical signal receiver, wherein the optical signal transmitter or identifier and the optical signal receiver are respectively arranged in a linear array on a first longitudinal beam and a second longitudinal beam, and the two longitudinal beams are arranged opposite to each other;

[0005] The optical signal transmitter or identifier includes a transmission wheel, an axle, a mounting plate, and a signal transmitter or identifier head. The axle is fixedly connected to the transmission wheel, the mounting plate is fixedly connected to the axle, and the signal transmitter or identifier head is mounted on the mounting plate coaxially with the axle. The transmission wheels of all optical signal transmitters or identifiers share a conveyor belt for synchronous transmission.

[0006] Preferably, when the transmission wheel rotates, the signal transmitting or identification head moves linearly back and forth relative to the mounting plate.

[0007] Furthermore, it also includes a bracket fixedly connected to one side of the transmission wheel, a rotating disk is rotatably mounted on the bracket, and a pin is protruding from the edge of the rotating disk;

[0008] A driving arm is also hinged on the bracket, and the driving arm includes a fan-shaped gear part and a linear arm fixed thereto. The fan-shaped gear part is meshed with a rack linearly slidably installed in the mounting plate. The center of the fan-shaped gear part is the hinge point of the driving arm on the bracket. The bar hole on the linear arm is slidably matched with the pin. When the rotating disk rotates, the driving arm is driven by the pin to drive the rack to move back and forth linearly, and the signal transmitting or identification head is fixed to the rack.

[0009] Furthermore, the bracket includes a Π-shaped door frame, and the rotating disk is rotatably installed in the center of the top beam of the door frame, and the hinge point is located at the end of the door frame on the side close to the mounting plate.

[0010] Furthermore, the gantry is fixedly connected to the wheel axle, a stepper motor is mounted on the top beam of the gantry, and a main shaft of the stepper motor is coaxially fixedly connected to the rotating disk.

[0011] Preferably, the rotating disk is a worm gear, the gantry is fixedly connected to the end face of the transmission wheel, and a rotating shaft parallel to the wheel axle is rotatably mounted on the inner side of the gantry. The rotating shaft has a worm section and a cylindrical gear section coaxially, the worm section is meshed with the worm wheel, the cylindrical gear section is meshed with a guide gear, and the guide gear is coaxially arranged with the wheel axle.

[0012] Furthermore, the guide gear is coaxially fixed on a core barrel, and the core barrel allows the wheel shaft to coaxially pass through and the two are rotationally matched.

[0013] Preferably, the core barrel is fixedly mounted in the first longitudinal beam.

[0014] Preferably, the core barrel is rotatably mounted in the first longitudinal beam, and a sprocket is coaxially fixed to the core barrel, the sprocket is drivingly connected to a chain, and the chain drives all the core barrels to rotate synchronously at the same time.

[0015] Furthermore, during installation, the infrared rays emitted by the signal transmitting or identification head of the present invention are not parallel to the wheel axle, so that when the signal transmitting or identification head rotates around the wheel axle, two conical monitoring areas are formed, and the tips of the two monitoring areas overlap, and the monitoring area on one side of the signal transmitting or identification head is smaller than the monitoring area on the other side; the signal transmitting or identification heads are arranged on the first longitudinal beam and the second longitudinal beam, and the signal transmitting or identification heads on the two longitudinal beams are not directly opposite to each other.

[0016] Compared with the prior art, the present invention has the following beneficial effects: the smart home security system provided by the present invention can use the method of actively emitting light or detecting and identifying light to perform anti-theft detection, and it also changes the disadvantage of the prior art that the optical signal transmission path is constant, and adopts a dynamic optical signal transmitter or identifier, which not only makes the emitted or identified light path flexible and changeable, but also makes the actual range that can be directly monitored larger. In this way, the user can decide whether to turn on the power device of the transmission wheel and the speed of the transmission wheel after turning it on, and independently choose whether to dynamically adjust the monitoring mode or actively adjust the monitoring range, so that the entire monitoring system is actually in a relative change and is not easy to avoid.

[0017] In addition, the present invention also specially arranges corresponding conical monitoring areas to more fully realize dynamic monitoring and minimize monitoring blind spots. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] In order to make the technical means, creative features, purpose and function of the present invention clearer and easier to understand, the technical solution of the present invention is described in detail below. Those skilled in the art should know that the following embodiments describe only some specific implementation structures or methods of the present invention, rather than all embodiments, and therefore, the protection scope of the present invention is not limited thereto.

[0027] This embodiment discloses a smart home security system. Figure 2-Figure 3 As shown, it mainly includes an alarm and an optical signal transmitter or identifier connected thereto, and an optical signal receiver 4, wherein the optical signal transmitter or identifier is used to emit an optical signal, or to identify an optical signal. For example, for emitting an optical signal, an invisible infrared ray 5 can be emitted, and the optical signal receiver 4 is used to match and receive the corresponding signal when there is an emitted optical signal. For example, when infrared ray 5 is used, the optical signal receiver 4 can receive infrared ray 5 signals. The optical signal receiver 4 is respectively arranged on the first longitudinal beam 2 and the second longitudinal beam 3 in a linear array, and the two longitudinal beams are arranged opposite to each other so as to perform intelligent anti-theft monitoring. In fact, the principle is mainly based on the current optical signal detection alarm. For example, this embodiment adopts the infrared ray 5 alarm mechanism. Specifically in this embodiment, the optical signal transmitter or identifier only has, or at least should have, the function of emitting infrared light. The optical signal transmitter or identifier mainly includes a power supply and a light source. The infrared light emitting diode emits one or more infrared light beams, and the emitted infrared ray 5 is received by the optical signal receiver 4. The infrared light signal is converted into an electrical signal by a photoelectric sensor, and then transmitted to the alarm after being analyzed and processed by a signal processor. Under normal circumstances, the optical signal transmitter or identifier emits infrared rays 5, and the optical signal receiver 4 receives a relatively stable optical signal. When someone passes through the monitored area, the infrared ray 5 beam is blocked, and the optical signal receiver 4 cannot receive the preset stable optical signal, thereby triggering the alarm to send out an alarm signal.

[0028] When the optical signal transmitter or identifier only has or at least has the function of identifying infrared rays 5 of a specific wavelength, then for burglary, the aforementioned optical signal transmitter or identifier can be replaced by an infrared identifier, and the optical signal receiver 4 can be selected not to be used. The selected infrared identifier can mainly identify infrared rays 5 of a wavelength of 10 microns generated by human body temperature, and then identify that someone has entered. However, this method is mainly for human detection, and there are certain limitations on the detection objects and conditions. The same applies to entry monitoring of other specific objects.

[0029] Based on the above basic principles, specifically, the aforementioned optical signal transmitter or identifier of this embodiment, such as Figure 2-3 , the structure should include a transmission wheel 6, an axle 7, a mounting plate 21, and a signal transmitter or identification head 23. Similarly, the signal transmitter or identification head 23 refers to an optical terminal that can emit light or identify specific light, and the axle 7 is fixedly connected to the transmission wheel 6 and can be made in one piece. The transmission wheel 6 is rotatably installed in the mounting cavity in the first longitudinal beam 2. Specifically, it can be a chain drive to synchronously drive all the transmission wheels 6, and the active part 10 driving the chain drive is directly controlled by the motor speed and the motor start-up time, which can more flexibly select whether the signal transmitter or identification head 23 moves, or whether it needs to temporarily change its position. At the same time, the mounting plate 21 can be a strip-shaped structure, and the mounting plate 21 is fixedly connected to the axle 7, for example, vertically fixed to the axle 7, and the signal transmitting or identification head 23 or the identification head that identifies the infrared ray 5 of a specific wavelength is installed on the mounting plate 21 coaxially with the axle 7, that is, the signal transmitting or identification head 23 and the axle 7 are not installed on the same horizontal line, and the driving wheels 6 of all optical signal transmitters or identifiers share a conveyor belt for synchronous transmission, so that all signal transmitting or identification heads 23 move synchronously.

[0030] In specific use, if an optical signal transmitter or identifier that only includes the optical signal transmission function is used, the emitted light beam can be dynamically adjusted. There are many specific ways to choose. For example, the above-mentioned signal transmitter or identification head 23 continuously rotates around the wheel axle 7, and the optical signal receiver 4 receives a circular track. Once someone enters the monitoring area 1, it may affect the optical track received by the optical signal receiver 4, thereby triggering an alarm. For another example, the signal transmitter or identification head 23 only rotates intermittently and adjusts its position continuously. Then, on the receiving end of the optical signal receiver 4, what is received at each place should be an optical signal that matches the corresponding position at the corresponding time; and if the time of this intermittent rotation is very long, it actually becomes a significantly differentiated adjustment of the position of the optical signal transmitter and identifier, and what is achieved is a significant adjustment of the monitoring target area.

[0031] Similarly, if an optical signal transmitter or identifier that only includes optical signal recognition function is used, then over a larger range, when the specific recognition head recognizes a specific wavelength, it can directly issue an alarm and indirectly indicate that a specific target has entered. Its effect is essentially similar to that of a combustible gas detector, which can detect specific gases.

[0032] It can be seen that this smart home security system has multiple monitoring functions, can flexibly adjust the monitoring target and range, and change the monitoring principle, so that the monitoring system does not adopt a single constant optical path monitoring mode, making it more difficult for targets to evade monitoring and improving anti-theft performance very intelligently.

[0033] In order to optimize the above effects, Figure 3-4 When the transmission wheel 6 rotates, the signal transmitting or identifying head 23 moves back and forth linearly relative to the mounting plate 21. At the same time, the present embodiment also includes a bracket fixedly connected to one side of the transmission wheel 6, on which a rotating disk 13 is rotatably mounted, and a pin 25 is protruding at the edge of the rotating disk 13, and the two are fixedly connected. A driving arm is also hingedly connected to the bracket, and the driving arm includes a fan-shaped gear part 14 and a linear arm 16 fixed thereto, and the fan-shaped gear part 14 is meshed with a rack 22 linearly slidably mounted in the mounting plate 21, and the bottom surface of the rack 22 is located in a strip hole (the number is not shown in the figure) on the mounting plate 21, so as to facilitate the meshing transmission of the fan-shaped gear part 14, and the center of the circle of the fan-shaped gear part 14 is the hinge point 15 of the driving arm on the bracket, and the strip hole on the linear arm 16 is slidably matched with the pin 25. When in use, once the rotating disk 13 rotates, it will drive the driving arm to rotate around the hinge point 15 through the pin 25, thereby achieving a reciprocating swing effect, and then the sector gear portion 14 can drive the rack 22 to move back and forth in a straight line when rotating around the hinge point 15. Since a signal transmitting or identification head 23 is fixedly connected to the rack 22, the signal transmitting or identification head 23 can rotate with the transmission wheel 6 while also moving back and forth radially, thereby forming a three-dimensional monitoring area 1, thereby improving the three-dimensional monitoring effect.

[0034] As a specific example, Figure 3-4 The bracket includes a Π-shaped door frame 12, a rotating disk 13 is rotatably installed in the center of the top beam of the door frame 12, and a hinge point 15 is located at the end of the door frame 12 on the side close to the mounting plate 21.

[0035] Specifically, if Figure 4 The gantry 12 is fixedly connected to the wheel axle 7, a stepper motor 24 is mounted on the top beam of the gantry 12, and the main shaft of the stepper motor 24 is coaxially fixedly connected to the rotating disk 13. Figure 3As shown, the rotating disk 13 is made into a worm wheel, the pin is fixed on the end face of the worm wheel near the edge, and the door frame 12 is fixedly connected to the end face of the transmission wheel 6. A rotating shaft 17 parallel to the wheel shaft 7 is rotatably installed inside the door frame 12. The rotating shaft 17 is coaxially provided with a worm segment 18 and a cylindrical gear segment 19. The worm segment 18 is meshed with the worm wheel, and the cylindrical gear segment 19 is meshed with a guide gear 20. The guide gear 20 is coaxially arranged with the wheel shaft 7. When the transmission wheel 6 is driven by an active member 10 such as a belt and rotates, The mounting plate 21 and the gantry 12, and a series of components fixed thereto will rotate synchronously, and the cylindrical gear segment 19 will rotate around the guide gear 20, causing the rotating shaft 17 to rotate, thereby causing the worm segment 18 to rotate, driving the worm wheel (rotating disk 13) to rotate, thereby causing the signal transmitter or identification head 23 installed on the rack 22 to rotate as well, thereby more flexibly changing the area range where the corresponding optical signal is generated, making the monitoring range more flexible and adjustable, and realizing dynamic adjustment of the monitoring area and method, which is difficult to avoid.

[0036] More specifically, in this embodiment, continue to refer to Figure 3 The guide gear 20 is coaxially fixed on a core barrel 8, and the core barrel 8 is coaxially passed by the wheel shaft 7 and the two are rotated in cooperation. At this time, one of the installation methods of the core barrel 8 is: fixedly installed in the first longitudinal beam 2 to provide an installation platform for the guide gear. Another ingenious installation structure is that the core barrel 8 is rotatably installed in the first longitudinal beam 2, and a sprocket 9 is coaxially fixed to the core barrel 8. The sprocket 9 is transmission-connected to a chain 11. The chain 11 drives all the core barrels 8 to rotate synchronously at the same time. When the chain 11 moves, it drives the sprocket 9 and the guide gear to rotate. The guide gear drives the cylindrical gear segment 19 and the worm segment 18 to rotate. The worm segment 18 drives the rotating disk 13 of the worm gear structure to rotate, and the signal transmitting or identification head 23 moves in a straight line. In this design, the rotation speed of the rotating disk 13 is not only affected by the rotation of the transmission wheel 6 itself, but also by the movement of the chain 11. The rotation speed of the rotating disk 13 is a superposition of the rotation speed of the transmission wheel 6 and the rotation speed of the sprocket 9, which is conducive to better realizing the adjustment and control of the linear motion speed of the signal transmitting or identification head 23.

[0037] Finally, a special design is that, when installing this embodiment, Figure 5 The infrared ray 5 emitted by its signal transmitting or identification head 23 is not parallel to the wheel axle 7, so that when the signal transmitting or identification head 23 rotates around the wheel axle 7, a Figure 6The two conical monitoring areas 1 shown in the figure have overlapping tips, and the monitoring area 1 on the side close to the signal transmitting or identifying head 23 is smaller than the monitoring area 1 on the other side; the signal transmitting or identifying heads 23 are arranged on the first longitudinal beam 2 and the second longitudinal beam 3, and the signal transmitting or identifying heads 23 on the two longitudinal beams are not directly opposite to each other, so that in a specific monitoring area, fewer optical signal transmitters or identifiers can be used to fully realize a more comprehensive monitoring of the corresponding monitoring area. This technical effect is compared with Figure 2 It can be clearly seen that the same size, Figure 2 The degree of coverage by the light curtain, or the detectable and identifiable area, is obviously denser.

[0038] It should be noted again that, in the present invention, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. Therefore, a person of ordinary skill in the art should be aware that any technical solution that any person of ordinary skill in the art can modify or replace the present embodiment based on the technical principles disclosed in the present invention without departing from the technical purpose of the present invention should be included in the protection scope of the present invention.
