Abstract

The present invention relates to the technical field of monitoring devices, and discloses an AI-based Internet of Things monitoring device and method for an intelligent park, including a guide rail, a support rod, a hollow rod, a fixing frame, and a camera. In the present invention, the hydraulic actuator on the side that needs to rotate is driven, which then drives the fixing block to rotate on the rotating rod, and presses and inclines the three stress bars that are not pulled, so that the pulled stress bar drives the fixing block to rotate. When it is necessary to rotate to the other side, the corresponding hydraulic actuator is driven in the direction that needs to rotate to prevent the camera from rotating automatically and causing rotation or pulling of the wire, avoiding damage to the wires connected to the camera after being rotated and pulled. Moreover, when the outer shell moves horizontally, the wire slides on the "U" shape inside the hollow bar by means of the ball, so that the wire extends upward and slides out from the inner side of the hollow bar, and the wire is spirally guided through the guiding structure, avoiding excessive elastic tension of the wire when the outer shell moves, and preventing damage caused by the wires folding against each other.

Description

Technical Field

[0001] The present invention relates to the technical field of monitoring devices, and specifically to an AI-based intelligent park Internet of Things monitoring device and method. Background Art

[0002] The Internet of Things is used to comprehensively sense, connect, analyze, and intelligently manage the facilities, equipment, and personnel in the park. The AI intelligent recognition of facilities, equipment, and personnel is mainly carried out by the cameras of the monitoring devices. The cameras of the monitoring devices include fixed brackets. Usually, the direction is adjusted by rotating the camera on the bracket. However, the camera rotates in multiple directions (front, back, left, and right) on the bracket, and when the camera needs to track the movement of personnel, it also needs to perform lifting activities. Rotation and lifting are likely to cause the wires passing through the bracket to be folded or pulled and damaged. And the wires are not formed into a complete guide and are likely to be folded and damaged, affecting the stability of the wires inside the bracket. Summary of the Invention

[0003] The present invention provides an AI-based intelligent park Internet of Things monitoring device and method, which overcomes the deficiencies described in the background art.

[0004] The technical solution adopted by the present invention to solve its technical problems is as follows:

[0005] An AI-based intelligent park Internet of Things monitoring device includes a guide rail, a support rod, a hollow rod, a fixed frame, and a camera. The hollow rod at the lower end of the camera is arranged at the upper end of the support rod. The support rod is supported and fixed on the side of the fixed frame. The guide rail is arranged on the wall, and the fixed frame moves vertically through the two guide rails;

[0006] The support rod is provided with a hollow structure, a driver, a housing, a flexible plate, a support plate, a wire, and a fixing block. The driver is arranged inside the housing. The support plate is arranged on the side of the driver and is arranged inside the hollow structure. The driver drives the support plate to expand and contract electrically and pulls the hollow structure to rotate;

[0007] The fixing block is movably connected to the right end of the hollow structure. The wire is electrically connected to the right end of the driver, and the wire passes through the inside of the fixing block and is electrically connected to the camera. The hollow structure is arranged at the right end of the flexible plate. When the driver pushes the support plate, it drives the hollow structure to compress and makes the fixing block rotate at the right end of the hollow structure.

[0008] A preferred technical solution: The driver is provided with a hydraulic rod, a limit block and a hydraulic device. The hydraulic device is arranged inside the limit block, and the limit block is engaged with the inner side of the housing. The hydraulic rod is installed on the output end of the hydraulic device. There are four hydraulic devices, which are distributed in a square shape, and the four hydraulic devices are connected in parallel by wire electrical signals. The left end of the wire is electrically connected to the inside of the fixing frame. The hydraulic rod is arranged on the side of the support plate, and the hydraulic device is driven by an electrical signal to expand and contract the hydraulic rod.

[0009] A preferred technical solution: The hollow structure is provided with a rotating rod, a corrugated plate and a stress bar. The corrugated plate is arranged on the side of the stress bar, and the corrugated plate is fixed to the right end of the stress bar. The support plate is arranged on the side of the stress bar. The rotating rod is movably fitted on the side of the fixed block. When one of the support plates pulls the stress bar to translate, the stress bar compresses the corrugated plate and causes the rotating rod on the side of one of the stress bars to pull the fixed block to rotate.

[0010] A preferred technical solution: The fixing frame is provided with a guiding structure, a housing, a fixing plate, a motor and a processor. The processor is installed inside the housing, and a fixing plate is arranged above the processor. The side of the processor is electrically connected to the wire. The motor is arranged inside the housing, and a roller is arranged at the output end of the motor. The motor is electrically connected to the inside of the processor to drive the roller at the output end of the motor to frictionally translate in the guide rail. The guiding structure is internally provided with an electric wire. One end of the electric wire passes through the fixing plate and is connected to the processor, and the other end of the electric wire passes through the upper end of the housing and is connected to the power supply. When the fixing frame moves, the electric wire is spirally wound up inside the guiding structure.

[0011] A preferred technical solution: The guiding structure is provided with a hollow strip, a ball and a blocking strip. The inner wall of the hollow strip is provided with balls, and the blocking strip is arranged at the inner opening of the hollow strip. The hollow strip is made of foam material, and the electric wire slides on the balls inside the hollow strip and the hollow strip is wound up.

[0012] Based on the above method for an AI-based intelligent park Internet of Things monitoring device, the specific method steps are as follows:

[0013] S1: The fixing frame controls the circuit of the electric wire through the processor, so that the current of the power supply is transmitted to the wire through the processor and then transmitted to the camera through the wire. When the camera rotates for monitoring, the hydraulic device in the driver is driven by an electrical signal, so that the hydraulic device drives the hydraulic rod to push, and the support plate drives the hollow structure to expand and contract, so that the fixed block rotates under the drive of one of the hydraulic devices and compresses the hollow structure.

[0014] S2: When one of the hydraulic cylinders is driven, the other three hydraulic cylinders are in a static state. Through the connection of the hydraulic rods to the support plate, the fixed block rotates at the position of the rotating rod, so that the fixed block compresses the force-bearing strip corrugated plate. The static force-bearing strip is pressed by the fixed block, and the static force-bearing strip tilts through the compression of the corrugated plate, driving the camera connected to the hollow rod at the upper end of the fixed block to rotate.

[0015] S3: The four hydraulic cylinders are distributed in a square shape and are driven according to the side that needs to rotate. After one of the hydraulic cylinders is driven, when the other side needs to rotate, the rotated hydraulic cylinder is reset, and an electric signal is used to drive the hydraulic cylinder on the other side that needs to rotate.

[0016] S4: When the processor drives the motor with an electric signal, the output end of the motor rolls and translates by friction within the guide rail, causing the housing to rise and fall within the two guide rails, thereby compressing the guiding structure in a spiral manner.

[0017] Compared with the prior art, this technical solution has the following advantages:

[0018] In the present invention, the hydraulic cylinder on the side where rotation is required is driven, and the support plate connected to the hydraulic rod is telescoped through the hydraulic cylinder, so that one of the force-bearing strips in the hollow structure is pulled. Subsequently, the fixed block rotates on the rotating rod, and the three force-bearing strips that are not pulled are pressed and tilted, so that the pulled force-bearing strip drives the fixed block to rotate. When rotation to the other side is required, the telescoped support plate is reset, and the corresponding hydraulic cylinder is driven in the direction that needs to rotate, preventing the camera from rotating on its own and causing rotation or pulling of the wires, and avoiding damage to the wires connected to the camera after being rotated and pulled.

[0019] In the present invention, when the housing translates, since one end of the wire passing through the housing is fixed to the power supply, and the translation of the housing pulls the wire to slide within the guiding structure, the wire slides on the "U" shape in the hollow strip by means of the ball. When the wire is stretched, the hollow strip is compressed by the pulling force of the wire, so that the wire extends and slides out upward from the inner side of the hollow strip. The guiding structure conducts spiral guidance on the wire, avoiding excessive elastic pulling force of the wire when the housing moves, and preventing damage caused by the wires being folded against each other.

[0029] As Figures 1 to 6 shown, in the present invention, an AI - based intelligent park Internet of Things monitoring device is proposed, including a guide rail 1, a support rod 2, a hollow rod 3, a fixing frame 4 and a camera 5. The hollow rod 3 at the lower end of the camera 5 is arranged at the upper end of the support rod 2. The support rod 2 is supported and fixed on the side of the fixing frame 4. The guide rail 1 is arranged on the wall, and the fixing frame 4 moves vertically through the two guide rails 1;

[0030] The support rod 2 is provided with a hollow structure 21, a driver 22, a housing 23, a flexible board 24, a support board 25, a wire 26 and a fixing block 27. The driver 22 is arranged inside the housing 23. The support board 25 is arranged on the side of the driver 22 and is arranged inside the hollow structure 21. The driver 22 drives the support board 25 to expand and contract electrically, and pulls the hollow structure 21 to rotate;

[0031] The fixing block 27 is movably connected to the right end of the hollow structure 21. The wire 26 is electrically connected to the right end of the driver 22, and the wire 26 passes through the inside of the fixing block 27 and is electrically connected to the camera 5. The hollow structure 21 is arranged at the right end of the flexible board 24. When the driver 22 pushes the support board 25, it drives the hollow structure 21 to compress, and makes the fixing block 27 rotate at the right end of the hollow structure 21.

[0032] Among them, the driver 22 is provided with a hydraulic rod 221, a limit block 222 and a hydraulic device 223. The hydraulic device 223 is arranged inside the limit block 222, and the limit block 222 is engaged with the inner side of the housing 23. The hydraulic rod 221 is installed on the output end of the hydraulic device 223. There are four hydraulic devices 223, and the four hydraulic devices 223 are distributed in a square shape. The four hydraulic devices 223 are electrically connected in parallel through a wire 26, and the left end of the wire 26 is electrically connected to the inside of the fixing frame 4. The hydraulic rod 221 is arranged on the side of the support plate 25, and the hydraulic device 223 is driven by an electrical signal to expand and contract the hydraulic rod 221.

[0033] Moreover, the flexible plate 24 is made of rubber material and has the effect of driving the hollow structure 21 to bend and deform. When one side of the hollow structure 21 rotates following the fixed block 27, the flexible plate 24 facilitates the bending of the hollow structure 21.

[0034] Moreover, the right ends of the four hydraulic devices 223 are electrically connected to the wire 26, and the left ends of the hydraulic devices 223 are electrically connected to the inside of the fixing frame 4 through the wire 26, and the hydraulic devices 223 are driven by the electrical signal control inside the fixing frame 4.

[0035] Among them, the hollow structure 21 is provided with a rotating rod 211, a corrugated plate 212 and a stress bar 213. The corrugated plate 212 is arranged on the side of the stress bar 213. The corrugated plate 212 is fixed to the right end of the stress bar 213. The support plate 25 is arranged on the side of the stress bar 213. The rotating rod 211 is movably matched with the side of the fixed block 27. When one of the support plates 25 pulls the stress bar 213 to translate, the stress bar 213 compresses the corrugated plate 212, and the rotating rod 211 on the side of one of the stress bars 213 pulls the fixed block 27 to rotate.

[0036] In the present invention, during the 5AI monitoring of the camera, it rotates. During rotation, the driver 22 inside the support rod 2 is driven by an electrical signal to operate, driving the hydraulic device 223 on the side that needs to rotate, and the support plate 25 connected to the hydraulic rod 221 is expanded and contracted through the hydraulic device 223, so that one of the stress bars 213 in the hollow structure 21 is pulled, and then the fixed block 27 is driven to rotate on the rotating rod 211, and the other three stress bars 213 that are not pulled are pressed and tilted, so that the pulled stress bar 213 drives the fixed block 27 to rotate. When it is necessary to rotate to the other side, the already expanded and contracted support plate 25 is reset, and the corresponding hydraulic device 223 is driven in the direction that needs to rotate, preventing the camera 5 from rotating automatically and generating rotation or pulling on the wire 26, and avoiding damage to the circuit connected to the camera 5 after being rotated and pulled.

[0037] Among them, the fixing frame 4 is provided with a guiding structure 41, a housing 42, a fixing plate 43, a motor 44 and a processor 45. The processor 45 is installed inside the housing 42, and a fixing plate 43 is provided at the upper end of the processor 45. The side of the processor 45 is electrically connected to the wire 26. The motor 44 is arranged inside the housing 42, and a roller is provided at the output end of the motor 44. The motor 44 is electrically connected inside the processor 45 to drive the roller at the output end of the motor 44 to frictionally translate in the guide rail 1. The guiding structure 41 is internally provided with an electric wire. One end of the electric wire passes through the fixing plate 43 and is connected to the processor 45, and the other end of the electric wire passes through the upper end of the housing 42 and is connected to the power supply. When the fixing frame 4 moves, the electric wire is spirally wound up inside the guiding structure 41.

[0038] Moreover, the roller at the output end of the motor 44 is made of rubber, and the roller presses against the inner side of the guide rail 1 and frictionally rolls on the inner side of the guide rail 1 when rotating.

[0039] Among them, the guiding structure 41 is provided with a hollow strip 411, a ball 412 and a blocking strip 413. The inner wall of the hollow strip 411 is provided with the ball 412. The blocking strip 413 is arranged at the inner opening of the hollow strip 411. The hollow strip 411 is made of foam material, and the electric wire slides on the ball 412 inside the hollow strip 411 and the hollow strip 411 winds up.

[0040] Moreover, the electric wire is fixed inside the fixing plate 43 below the guiding structure 41, while the upper end of the electric wire passes through the housing 42 and is connected to the power supply without being fixed. When the housing 42 moves, the electric wire slides inside the hollow strip 411 and moves upward out of the guiding structure 41, and compresses the guiding structure 41, reducing the elastic tension of the electric wire.

[0041] In the present invention, the processor 45 drives the output end of the motor 44 to rotate, and makes the roller frictionally rotate in the guide rail 1, so that the housing 42 moves up and down and translates in the guide rail 1. When the housing 42 translates, since one end of the electric wire passing through the housing 42 is fixed to the power supply, and the translation of the housing 42 pulls the electric wire to slide inside the guiding structure 41, the electric wire is slid by the ball 412 on the "U" shape inside the hollow strip 411. When the electric wire is stretched, the hollow strip 411 is compressed by the pulling force of the electric wire, so that the electric wire extends upward and slides out from the inner side of the hollow strip 411. The guiding structure 41 spirally guides the electric wire, avoiding excessive elastic tension of the electric wire when the housing 42 moves, and preventing damage caused by the wires being folded against each other.

[0042] Based on the above method of an AI-based intelligent park Internet of Things monitoring device, the specific method steps are as follows:

[0043] S1: The fixing bracket 4 controls the circuit of the electric wire through the processor 45, so that the current of the power supply is transmitted to the wire 26 after passing through the processor 45 and is transmitted to the camera 5 through the wire 26. When the camera 5 rotates for monitoring, the electric signal drives the hydraulic device 223 in the driver 22, so that the hydraulic device 223 drives the hydraulic rod 221 to push, and the support plate 25 drives the hollow structure 21 to expand and contract. Thus, the fixing block 27 rotates under the drive of one of the hydraulic devices 223 and compresses the hollow structure 21.

[0044] S2: When one of the hydraulic devices 223 is driven, the other three hydraulic devices 223 are in a static state. Through the connection between the hydraulic rod 221 and the support plate 25, the fixing block 27 rotates at the position of the rotating rod 211. Thus, the fixing block 27 compresses the corrugated plate 212 through the stress bar 213, and the static stress bar 213 is pressed by the fixing block 27. The static stress bar 213 undergoes an inclined movement through the compression of the corrugated plate 212 and drives the camera 5 connected to the hollow rod 3 at the upper end of the fixing block 27 to rotate.

[0045] S3: The four hydraulic devices 223 are distributed in a square shape and are driven according to the side that needs to rotate. After one of the hydraulic devices 223 is driven, when the other side needs to rotate, the driven hydraulic device 223 is reset, and an electric signal is used to drive the hydraulic device 223 on the other side that needs to rotate.

[0046] S4: When the processor 45 drives the motor 44 with an electric signal, the output end of the motor 44 rolls and translates by friction in the guide rail 1, and the housing 42 rises and falls in the two guide rails 1. Thus, the guiding structure 41 is spirally compressed.

[0047] It should be noted that the guiding structure 41 in the present invention is different from the electric coil integrated with the electric wire thread. The elasticity between the threads formed by the electric coil is too large, which is likely to pull the electric wire. In the present invention, the electric wire is limited to slide within the guiding structure 41, and the electric wire expands and contracts through the compression between the guiding structures 41. The compression of the guiding structure 41 forms a state of guiding and extending the electric wire. Since the hollow strip 411 is made of foam material and has weak elasticity, the spiral hollow strip 411 has a certain guiding force, avoiding the excessive elasticity of the electric wire thread forming a loop and causing pulling.

[0048] The above is only a preferred embodiment of the present invention, and thus the scope of implementation of the present invention cannot be limited thereby. That is, equivalent changes and modifications made according to the scope of the present invention patent and the content of the specification should still fall within the scope covered by the present invention.
