[0001] The present invention relates to the technical field of Internet of Things anti-theft, and in particular to an anti-theft system based on the Internet of Things. Background Art

[0002] With the continuous improvement of living standards, people pay more and more attention to the protection of family security. Therefore, a reliable and practical home security system has become a need for many people. However, current security systems have many limitations, such as how to configure and place the monitoring units in the security system, how to effectively transmit various detection data to the householder, how to alarm, how to respond, etc. The Internet of Things refers to the combination of technology with computers and Internet technology to achieve real-time sharing of environmental and status information between objects, as well as intelligent collection, transmission, processing, and execution to achieve deeper Internet of Things.

[0003] When the control host in the existing Internet of Things anti-theft system is working, it usually dissipates heat through the outside air, which cannot achieve effective heat dissipation effect, resulting in a limited service life. In addition, the camera is not easy to disassemble and assemble, making it inconvenient to maintain. Summary of the invention

[0018] One end of the driving shaft 8 located in the circular cavity 6 is fixedly connected to a gear 9, and a circular frame 10 fixedly connected to the circular cavity 6 is provided on the outer side of the gear 9, and a tooth groove meshing with the gear 9 is opened on the surface of the circular frame 10, and a cooling fan 11 is fixedly installed on the end of the driving motor 7 away from the driving shaft 8, and the cooling fan 11 is set towards the control host 2. When the device needs to dissipate heat during use, the driving motor 7 and the cooling fan 11 are started. The driving motor 7 can drive the gear 9 to rotate through the driving shaft 8, so that the gear 9 rolls along the surface of the circular frame 10 through the tooth groove meshing therewith, and the cooling fan 11 can be driven to circulate around the outer side of the control host 2, thereby increasing the heat dissipation range of the control host 2, improving the heat dissipation effect of the control host 2, and thus extending the service life of the control host 2.

[0019] The surface of the fixing plate 1 is equipped with a camera 4, an alarm light 5 and a speaker 28. The camera 4 is used to collect information. The alarm light 5 can emit a flashing light when an alarm is required to remind the staff, and the speaker 28 can sound an alarm when an alarm is required. The surfaces of the alarm light 5 and the speaker 28 are respectively fixedly connected with a first stud 19 and a second stud 20 threadedly connected to the surface of the fixing plate 1. The surface of the fixing plate 1 is provided with a first thread groove 21 and a second thread groove 22 threadedly connected to the first stud 19 and the second stud 20, respectively. When the alarm light 5 and the speaker 28 When damaged and needing repair or replacement, rotate the alarm light 5 and the speaker 28, and turn the first stud 19 and the second stud 20 out of the first thread groove 21 and the second thread groove 22 respectively, so that the alarm light 5 and the speaker 28 can be disassembled for repair or replacement. After the repair or replacement is completed, the first stud 19 and the second stud 20 on the alarm light 5 and the speaker 28 can be respectively inserted into the first thread groove 21 and the second thread groove 22, thereby enabling the installation and disassembly of the alarm light 5 and the speaker 28, facilitating the repair or replacement of the alarm light 5 and the speaker 28.

The side wall of the dust cover 26 is fixedly connected with a door-type handle 27. When the speaker 28 needs to be installed or disassembled, the dust cover 24 can be flipped down first and opened to install or disassemble the speaker 28.

[0021] A disassembly and assembly mechanism is provided between the camera 4 and the fixed plate 1, and the disassembly and assembly mechanism includes a fixed column 13 fixedly connected to the surface of the fixed plate 1, the outer wall fixed sleeve of the fixed column 13 is provided with a fixed ring 15, the outer wall movable sleeve of the fixed ring 15 is provided with a screw sleeve 16 movably sleeved on the outer wall of the fixed column 13, and the fixed ring 15 can ensure that the position of the screw sleeve 16 will not move and can only be rotated.

[0022] A rectangular rod 14 is slidably inserted into the end of the fixing column 13 away from the fixing plate 1, and a rectangular groove 18 matching the rectangular rod 14 is opened at the end of the fixing column 13, which can play a role in limiting the subsequent screw 17, so that the screw 17 will not rotate on its own. The end of the rectangular rod 14 away from the fixing column 13 is fixedly connected to the screw 17 fixedly connected to the surface of the camera 4. When installing the camera 4, the rectangular rod 14 is first inserted into the rectangular groove 18, and then the screw sleeve 16 is rotated to utilize the engagement with the screw 17, so that the screw 17 radially approaches the fixing column 13 under the limitation of the rectangular rod 14 and the rectangular groove 18 until the screw 17 can no longer move, and the camera 4 can be installed. When disassembling, the screw sleeve 16 can be rotated in the opposite direction, so as to achieve the effect of quick disassembly and assembly of the camera 4.

[0023] The working principle of the present invention is as follows: when in use, the device can be fixed on the wall at the designated position by using a plurality of screws or rivets to pass through each mounting hole 25 respectively. Then, when installing the camera 4, the rectangular rod 14 is first inserted into the rectangular groove 18, and then the screw sleeve 16 is rotated to engage with the screw 17, so that the screw 17 is radially close to the fixing column 13 under the limit of the rectangular rod 14 and the rectangular groove 18 until the screw 17 can no longer move, and the camera 4 can be installed. Then, the information collected by the camera 4 is transmitted to the control host 2, and the control host 2 controls whether the alarm light 5 and the speaker 28 alarm. At the same time, the drive motor 7 and the cooling fan 11 are started. The drive motor 7 can drive the gear 9 to rotate through the drive shaft 8, so that the gear 9 rolls along the surface of the circular frame 10 through the tooth groove meshing therewith, and the cooling fan 11 can be driven to move around the outer side of the control host 2 in a circular motion, thereby increasing the heat dissipation range of the control host 2, improving the heat dissipation effect of the control host 2, and thus extending the service life of the control host 2.

[0024] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
