Description

Technical Field

[0001] This invention belongs to the technical field of inspection and early warning equipment, specifically relating to an inspection and early warning robot for use in a safety seat production workshop. Background Technology

[0002] Inspection and early warning robots are intelligent devices that integrate environmental perception, data collection, anomaly identification, and real-time early warning functions. Their core purpose is to replace manual labor in automated inspections and risk control across various scenarios. In a child safety seat production workshop, these robots can monitor the workshop environment (such as dust concentration and equipment temperature) and operating procedures (such as personnel not wearing protective equipment as required or illegally approaching hazardous workstations) 24 hours a day, providing timely warnings of safety hazards such as fires and equipment overloads.

[0003] In existing designs of inspection and early warning robots used in child safety seat production workshops, a lifting mechanism is typically used to raise and lower the data acquisition camera to comprehensively collect information from the workshop. This allows the camera to capture data from different heights. However, because the supporting area between the robot's bottom trolley and the ground remains constant, the robot's stability decreases as the data acquisition camera is raised. This can easily lead to the robot tilting or even tipping over during movement. Furthermore, the top camera may shake during the raised movement, resulting in inaccurate data collection from the child safety seat production workshop.

[0004] Therefore, in order to address the aforementioned technical issues, it is necessary to provide an inspection and early warning robot for use in a child safety seat production workshop.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide an inspection and early warning robot for use in a child safety seat production workshop, which can solve the problem of low stability of the existing inspection and early warning robots after the top data acquisition camera is raised.

[0007] To achieve the above objectives, a specific embodiment of the present invention provides the following technical solution: An inspection and early warning robot for use in a child safety seat production workshop includes: a mobile base, a lifting seat, a data acquisition camera, an auxiliary support mechanism, and an auxiliary movement mechanism.

[0008] The bottom of the mobile base is equipped with two pairs of casters. The lifting seat is fixed to the top of the mobile base, and a lifting rod is slidably installed inside it. A mounting base is fixed to one end of the lifting rod at the top of the lifting seat, and a lifting assembly is installed between the lifting seat and the lifting rod. The acquisition camera is installed on the top of the mounting base.

[0009] The auxiliary support mechanism is installed between the two side walls of the lifting seat and the mounting base. The auxiliary support mechanism includes: a pair of mounting slots, a pair of support plates, two pairs of sliders, a pair of control rods, two pairs of clamping rods, and an elastic control component. The pair of mounting slots are respectively carved into the two side walls of the lifting seat, and each side wall of the pair of mounting slots has a sliding groove. A pair of sliders are fixed to the bottom ends of the two side walls of the pair of support plates. The two pairs of sliders slide within the two pairs of sliding grooves. Multiple sliding sleeves are fixed to the inner walls of the pair of support plates. The pair of control rods slide within the multiple sliding sleeves, and their top ends are rotatably connected to the side wall of the mounting base, while their bottom ends are fixed with connecting blocks. The two pairs of clamping rods slide within the two pairs of sliders, and each end of the clamping rod located within the support plate is connected to the connecting block with a rotating component. The elastic control component is installed between the control rods and the support plates, and is used to control the control rods to push the pair of clamping rods tightly against the side walls of the pair of sliding grooves.

[0010] The auxiliary moving mechanism is installed at the bottom of the movable base. The auxiliary moving mechanism includes: an inner groove, a moving block, a C-shaped moving component, two pairs of Z-shaped support rods, two pairs of auxiliary wheels, and a sliding control assembly. The inner groove is carved into the bottom wall of the movable base, and a pair of second sliding rods and a pair of first sliding rods are fixedly and vertically offset within the inner groove. The moving block and the C-shaped moving component slide on the pair of first sliding rods and the pair of second sliding rods, respectively, and are offset from each other. The two pairs of Z-shaped support rods rotate on the side walls of the moving block and the C-shaped moving component, respectively, and a connecting plate is fixed to the outer end of each pair of Z-shaped support rods. The two pairs of auxiliary wheels are respectively installed on the pair of connecting plates. The sliding control assembly is installed within the inner groove and is used to drive the moving block and the C-shaped moving component to slide simultaneously in opposite directions.

[0011] In one embodiment of the present invention, the lifting assembly includes a lead screw and a threaded groove. The lead screw rotates on a movable base, and its top end is located within the lifting seat. One end of the lead screw located within the movable base is connected to a drive motor. The threaded groove is carved into the lifting rod, and one end of the lead screw located within the lifting seat is threadedly connected to the threaded groove. In use, the drive motor drives the lead screw to rotate. Because the lead screw is threadedly connected to the threaded groove, when the lead screw rotates, it drives the lifting rod to move up and down within the lifting seat.

[0012] In one embodiment of the present invention, a pair of radar sensors are provided at both the front and rear ends of the movable base, and a collision protection strip is installed on the outer side wall of the movable base. Multiple collision sensors are provided on the four sides of the collision protection strip. The radar sensors are used to identify and scan obstacles in front, enabling the device to change its movement path in time and overcome the obstacles. The collision protection strip protects the side walls of the movable base, and the multiple collision sensors prevent collisions.

[0013] In one embodiment of the present invention, guide limiting grooves are carved on each of the two inner sidewalls of the lifting seat, and a pair of guide limiting blocks are fixed to the bottom ends of each of the two outer sidewalls of the lifting rod. The pair of guide limiting blocks slide within the pair of guide limiting grooves. By sliding the pair of guide limiting blocks within the pair of guide limiting grooves, the lifting seat is guided when it slides up and down, and the highest and lowest positions that the lifting seat can move upward and downward are limited.

[0014] In one embodiment of the present invention, connecting seats are fixed to both side walls of the mounting base, and connecting heads are fixed to the top ends of the pair of control rods, with the connecting heads rotating on the connecting seats. The top ends of the control rods are rotatably connected to the side walls of the mounting base via the connecting heads rotating on the connecting seats. Rotating heads are fixed to both sides of the connecting block and one end of the pair of clamping rods located within the support plate, and the two ends of the rotating component are respectively rotatably connected to the pair of rotating heads. Rotatable connections are achieved between the two sides of the connecting block and the one end of the pair of clamping rods located within the support plate via the rotating heads and the rotating components.

[0015] In one embodiment of the present invention, the elastic control assembly includes: a pair of fixed plates, a control plate, and a pair of elastic members. The pair of fixed plates are respectively fixed to one end of two adjacent sliding sleeves that are close to each other. The control plate is fixed to a control rod and disposed between the pair of fixed plates. The pair of elastic members are respectively installed between the pair of fixed plates and the control plate. Through the interaction of the elastic forces of the pair of elastic members, the control plate is pushed up and down, moving to the middle position of the pair of fixed plates. This causes the control plate to move the control rod up and down, moving the connecting block to the middle position of the pair of clamping rods. The connecting block, through a pair of rotating members, pushes the outer ends of the pair of clamping rods to clamp against the sidewalls of the pair of sliding grooves, thereby fixing the support plate.

[0016] In one embodiment of the present invention, an elastic plate is also fixed to the control rod, and a locking head is fixed to one end of the elastic plate near the side wall of the support plate. A slot adapted to the locking head is fixed on the inner wall of the support plate. When the control rod moves up and down, causing the connecting block to move to the middle position of a pair of clamping rods, the elastic force of the elastic plate pushes the locking head into the slot, thereby preventing the control rod from wobbling up and down, thus ensuring the stability of the support plate and the control rod in supporting the lifting rod. Both the locking head and the slot are hemispherical.

[0017] In one embodiment of the present invention, the sliding control assembly includes: two pairs of bearing seats, a pair of drive shafts, and a drive belt. The two pairs of bearing seats are respectively fixed to the two outer side walls of the inner groove. The pair of drive shafts rotates on the two pairs of bearing seats, and each drive shaft has a drive wheel fixed between the pair of bearing seats. The drive belt is mounted on the pair of drive wheels, and the top wall of the C-shaped moving member and the bottom wall of the moving block are both fixed to the drive belt.

[0018] One of the pair of drive shafts needs to be connected to a reciprocating drive motor during use to drive it to move back and forth. The drive shaft drives the drive belt to rotate through the drive wheel, causing the drive belt to drive the moving block and the C-shaped moving part to slide in opposite directions at the same time, so that the moving block and the C-shaped moving part slide from one end of the inner groove to the other end at the same time.

[0019] In one embodiment of the present invention, a pair of L-shaped limiting rods are fixed to the bottom ends of both sides of the inner groove. Each pair of L-shaped limiting rods is located on the outside of each pair of Z-shaped support rods, and pulleys are installed at one end of each pair of L-shaped limiting rods at the bottom of the Z-shaped support rods. When the moving block and the C-shaped moving part pull a pair of auxiliary wheels back to the bottom of the moving base via a pair of Z-shaped support rods, by setting a pair of pulleys and making the pair of Z-shaped support rods slide on the pair of pulleys when they are retracted, the outer ends of the pair of Z-shaped support rods rotate upwards, causing the pair of auxiliary wheels to retract to the bottom of the moving base while also lifting upwards, preventing them from obstructing the movement of the moving base.

[0020] A patrol and early warning robot for a child safety seat production workshop also includes a workshop patrol system. The workshop patrol system comprises a workshop information acquisition module, a data processing module, a control module, and an early warning communication module. The workshop information acquisition module collects data from within the child safety seat production workshop and transmits the collected information to the data processing module for analysis. If the data processing module analyzes abnormal equipment operation within the workshop, and if the abnormal equipment is a network-controlled device, it can be remotely controlled directly through the control module to shut down the equipment or restore it to normal operation. If the equipment cannot be remotely controlled, the early warning communication module notifies the workshop operators for manual troubleshooting.

[0021] Secondly, by simultaneously controlling the sliding block and the C-shaped moving part to slide from one end of the inner groove to the other through the sliding control component, the moving block and the moving part push the two pairs of auxiliary wheels outwards from the two sides of the moving base through the two pairs of Z-shaped support rods. The top wall of one end of the Z-shaped support rod is attached to the bottom end of the side wall of the inner groove, so that the two pairs of auxiliary wheels are supported on the ground. This increases the support area between the moving base and the ground, thereby improving the stability of the moving base when it moves, and thus improving the accuracy of data collection in the safety seat production workshop.

[0022] Compared with the prior art, the present invention provides an inspection and early warning robot for a safety seat production workshop. First, a pair of support plates are set up to provide auxiliary support for the lifting rod after it is raised and lowered. Then, through the elastic force of a pair of elastic elements, the control rod pushes a pair of clamping rods outward to clamp onto the side walls of a pair of sliding grooves through the connecting block and a pair of rotating elements. Thus, after the lifting rod drives the support plate to rise to the specified height, the support plate is fixed, so that the support plate provides auxiliary support for the top of the lifting rod.

Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0027] like Figures 1 to 10 As shown, an inspection and early warning robot for a safety seat production workshop according to one embodiment of the present invention includes: a mobile base 1, a lifting seat 102, a data acquisition camera 104, an auxiliary support mechanism 2, and an auxiliary moving mechanism 3.

[0028] like Figures 1 to 10 As shown, the bottom of the movable base 1 is equipped with two pairs of casters 101. A lifting seat 102 is fixed to the top of the movable base 1, and a lifting rod 103 is slidably mounted inside it. A mounting base 113 is fixed to one end of the lifting rod 103 at the top of the lifting seat 102. A lifting assembly is installed between the lifting seat 102 and the lifting rod 103. A camera 104 is mounted on the top of the mounting base 113.

[0029] The mobile base 1 uses two pairs of wheels 101 at its bottom to move the acquisition camera 104. The lifting seat 102 is used to slide the lifting rod 103 up and down, and also supports the lifting rod 103 and the acquisition camera 104. The lifting assembly is used to move the lifting rod 103 up and down, which in turn moves the acquisition camera 104 up and down. The acquisition camera 104 is used to scan and collect information about the working environment in the safety seat production workshop.

[0030] like Figures 1 to 10 As shown, the auxiliary support mechanism 2 is installed between the two side walls of the lifting seat 102 and the mounting base 113. The auxiliary support mechanism 2 includes: a pair of mounting grooves 201, a pair of support plates 203, two pairs of sliders 204, a pair of control rods 206, two pairs of clamping rods 210, and an elastic control assembly. The pair of mounting grooves 201 are respectively carved into the two side walls of the lifting seat 102, and each side wall of the pair of mounting grooves 201 has a sliding groove 202 carved into it. A pair of sliders 204 are fixed to the bottom ends of the two side walls of the pair of support plates 203. The two pairs of sliders 204 slide within the two pairs of sliding grooves 202. Multiple sliding sleeves 212 are fixed to the inner walls of the pair of support plates 203. The pair of control rods 206 slide within the multiple sliding sleeves 212, and their top ends are rotatably connected to the side wall of the mounting base 113, while their bottom ends are fixed with connecting blocks 208. Two pairs of clamping rods 210 slide within two pairs of sliders 204, and each end of the clamping rod 210 located within the support plate 203 is connected to a rotating element 209 between it and the connecting block 208. An elastic control assembly is installed between the control rod 206 and the support plate 203 to control the control rod 206 to push a pair of clamping rods 210 against the sidewalls of a pair of sliding grooves 202.

[0031] The auxiliary support mechanism 2 provides auxiliary support to the lifting rod 103 after it raises the acquisition camera 104, ensuring the camera maintains a stable shooting position. The mounting groove 201 houses the support plate 203, and the sliding groove 202 allows a pair of sliders 204 at the bottom of the side wall of the support plate 203 to slide within it. Multiple sliding sleeves 212 allow the control rod 206 to slide up and down within them. The control rod 206 is rotatably connected to the side wall of the mounting base 113, and the support plate 203 and the mounting base 113 are elastically connected via the control rod 206 and the elastic control assembly. In addition, the control lever 206, through the elastic control component, can be reset to the position where the connecting block 208 is located between the pair of clamping rods 210 after sliding up and down on the support plate 203. The connecting block 208 pushes the pair of clamping rods 210 outward through the pair of rotating parts 209, and clamps the outer end of the clamping rods 210 onto the side wall of the slide groove 202, thereby fixing the bottom end of the support plate 203. Furthermore, the outer ends of the pair of clamping rods 210 are provided with anti-slip silicone pads.

[0032] In use, when the lifting rod 103 drives the control rod 206 to move upward, the pair of clamping rods 210 are clamped outward on the side wall of the slide groove 202. Therefore, the lifting rod 103 cannot initially drive the support plate 203 to move upward. At this time, the lifting rod 103 can only drive the control rod 206 to move upward. The control rod 206 pulls the clamping rods 210 inward into the support plate 203 through the connecting block 208 and the pair of rotating parts 209, so that the outer ends of the pair of clamping rods 210 are released from the inner wall of the slide groove 202. When the lifting rod 103 stops moving upward, the control rod 206 is pushed back to its original position by the action of the elastic control component. This causes the control rod 206 to push the pair of clamping rods 210 outward from the support plate 203 through the connecting block 208 and the pair of rotating parts 209, so that the outer ends of the pair of clamping rods 210 are clamped to the inner wall of the slide groove 202, thereby fixing the bottom end of the support plate 203.

[0033] When the lifting rod 103 moves the control rod 206 downward, it also pulls a pair of clamping rods 210 back into the support plate 203. When the movement stops, the outer ends of the pair of clamping rods 210 are clamped onto the inner wall of the slide groove 202 again by the action of the elastic control component, thereby fixing the bottom end of the support plate 203.

[0034] like Figures 1 to 10 As shown, the auxiliary moving mechanism 3 is installed at the bottom of the movable base 1. The auxiliary moving mechanism 3 includes: an inner groove 301, a moving block 304, a C-shaped moving part 305, two pairs of Z-shaped support rods 310, two pairs of auxiliary wheels 312, and a sliding control assembly. The inner groove 301 is carved into the bottom wall of the movable base 1. A pair of second slide rods 303 and a pair of first slide rods 302 are fixedly and vertically offset within the inner groove 301. The moving block 304 and the C-shaped moving part 305 slide on the pair of first slide rods 302 and the pair of second slide rods 303, respectively, and the moving block 304 and the C-shaped moving part 305 are offset from each other. The two pairs of Z-shaped support rods 310 rotate on the side walls of the moving block 304 and the C-shaped moving part 305, respectively, and a connecting plate 311 is fixed to the outer end of each pair of Z-shaped support rods 310. Two pairs of auxiliary wheels 312 are respectively mounted on a pair of connecting plates 311, and the sliding control component is installed in the inner groove 301 to drive the moving block 304 and the C-shaped moving part 305 to slide in opposite directions at the same time.

[0035] The auxiliary moving mechanism 3 is used to increase the support area between the mobile base 1 and the ground after the acquisition camera 104 is raised, thereby improving the stability of the mobile base 1 during movement. Additionally, the moving block 304 and the C-shaped moving member 305 slide alternately within a pair of staggered first slide rods 302 and a pair of second slide rods 303. The C-shaped moving member 305 is C-shaped with its opening facing downwards, so that when the moving block 304 and the C-shaped moving member 305 slide simultaneously in opposite directions, they do not obstruct each other. A sliding control component is used to drive the moving block 304 and the C-shaped moving member 305 to slide simultaneously in opposite directions. Furthermore, when the moving block 304 and the C-shaped moving member 305 each extend the auxiliary wheel 312 outwards from the mobile base 1 via a pair of Z-shaped support rods 310, the upper top wall of the Z-shaped support rod 310 fits against the bottom end of the side wall of the inner groove 301, thus supporting the pair of auxiliary wheels 312 on the ground.

[0036] like Figures 1 to 10 As shown, the lifting assembly includes a lead screw 105 and a threaded groove 107. The lead screw 105 rotates on the movable base 1, and its top end is located within the lifting seat 102. One end of the lead screw 105 located within the movable base 1 is connected to a drive motor 106. The threaded groove 107 is carved into the lifting rod 103, and one end of the lead screw 105 located within the lifting seat 102 is threadedly connected to the threaded groove 107. In use, the drive motor 106 drives the lead screw 105 to rotate. Since the lead screw 105 is threadedly connected to the threaded groove 107, when the lead screw 105 rotates, it drives the lifting rod 103 to move up and down within the lifting seat 102.

[0037] like Figures 1 to 10 As shown, a pair of radar sensors 111 are installed at both the front and rear ends of the mobile base 1. Anti-collision strips 110 are installed on the outer side walls of the mobile base 1, and multiple collision sensors 112 are installed on the four sides of the anti-collision strips 110. The radar sensors 111 are used to identify and scan obstacles in front, enabling the device to change its movement route in time and overcome obstacles. The anti-collision strips 110 provide protection for the side walls of the mobile base 1, and the multiple collision sensors 112 are used to prevent collisions.

[0038] like Figures 1 to 10 As shown, guide and limiting grooves 108 are carved on both inner sidewalls of the lifting seat 102, and a pair of guide and limiting blocks 109 are fixed to the bottom ends of both outer sidewalls of the lifting rod 103. The pair of guide and limiting blocks 109 slide within the pair of guide and limiting grooves 108. By sliding the pair of guide and limiting blocks 109 within the pair of guide and limiting grooves 108, the lifting seat 102 is guided when it slides up and down, and the highest and lowest positions that the lifting seat 102 can move upward and downward are limited.

[0039] like Figures 1 to 10 As shown, connecting seats 205 are fixed to both side walls of the mounting base 113, and connecting heads 207 are fixed to the top ends of a pair of control rods 206. The connecting heads 207 rotate on the connecting seats 205. The top ends of the control rods 206 rotate on the connecting seats 205 through the connecting heads 207, thereby rotatably connecting to the side walls of the mounting base 113. Rotating heads 211 are fixed to both sides of the connecting block 208 and one end of the pair of clamping rods 210 located within the support plate 203. The two ends of the rotating component 209 are rotatably connected to the pair of rotating heads 211 respectively. Rotatably connected to the rotating component 209 through the rotating heads 211 at both sides of the connecting block 208 and one end of the pair of clamping rods 210 located within the support plate 203.

[0040] like Figures 1 to 10 As shown, the elastic control assembly includes: a pair of fixed plates 213, a control plate 214, and a pair of elastic members 215. The pair of fixed plates 213 are respectively fixed to the ends of two adjacent sliding sleeves 212, close to each other. The control plate 214 is fixed to the control rod 206 and positioned between the pair of fixed plates 213. The pair of elastic members 215 are respectively installed between the pair of fixed plates 213 and the control plate 214. Through the interaction of the elastic forces of the pair of elastic members 215, the control plate 214 is pushed up and down, moving to the middle position of the pair of fixed plates 213. This causes the control plate 214 to move the control rod 206 up and down, moving the connecting block 208 to the middle position of the pair of clamping rods 210. The connecting block 208, through a pair of rotating members 209, pushes the outer ends of the pair of clamping rods 210 to clamp onto the side walls of the pair of sliding grooves 202, thereby fixing the support plate 203.

[0041] like Figures 1 to 10 As shown, an elastic plate 216 is also fixed on the control rod 206. A locking head 217 is fixed to one end of the elastic plate 216 near the side wall of the support plate 203. A slot 218 that matches the locking head 217 is fixed on the inner wall of the support plate 203. When the control rod 206 moves up and down, causing the connecting block 208 to move to the middle position of a pair of clamping rods 210, the elastic force of the elastic plate 216 pushes the locking head 217 to lock in the slot 218, thereby preventing the control rod 206 from shaking up and down. This ensures the stability of the support plate 203 and the control rod 206 in supporting the lifting rod 103. Both the locking head 217 and the slot 218 are hemispherical.

[0042] like Figures 1 to 10As shown, the sliding control assembly includes: two pairs of bearing seats 306, a pair of drive shafts 307, and a drive belt 309. The two pairs of bearing seats 306 are respectively fixed to the two outer side walls of the inner groove 301. The pair of drive shafts 307 rotate on the two pairs of bearing seats 306, and each shaft 307 has a drive wheel 308 fixed between it. The drive belt 309 is mounted on the pair of drive wheels 308, and the top wall of the C-shaped moving member 305 and the bottom wall of the moving block 304 are both fixed to the drive belt 309.

[0043] One of the pair of drive shafts 307 needs to be connected to a reciprocating drive motor during use to drive it to move back and forth. The drive shaft 307 drives the drive belt 309 to rotate through the drive wheel 308, so that the drive belt 309 drives the moving block 304 and the C-shaped moving part 305 to slide in opposite directions at the same time, so that the moving block 304 and the C-shaped moving part 305 slide from one end of the inner groove 301 to the other end at the same time.

[0044] like Figures 1 to 10 As shown, a pair of L-shaped limiting rods 313 are fixed to the bottom of both sides of the inner groove 301. Each pair of L-shaped limiting rods 313 is located on the outside of each pair of Z-shaped support rods 310. A pulley 314 is installed at one end of each pair of L-shaped limiting rods 313 at the bottom of the Z-shaped support rods 310. When the moving block 304 and the C-shaped moving part 305 pull a pair of auxiliary wheels 312 back to the bottom of the moving base 1 through a pair of Z-shaped support rods 310, a pair of pulleys 314 are provided, and the pair of Z-shaped support rods 310 slide on the pair of pulleys 314 when they are retracted. At this time, the outer ends of the pair of Z-shaped support rods 310 rotate upward, so that the pair of auxiliary wheels 312 are retracted to the bottom of the moving base 1 and also lifted upward, preventing them from hindering the movement of the moving base 1.

[0045] A patrol and early warning robot for a child safety seat production workshop also includes a workshop patrol system. The workshop patrol system comprises a workshop information acquisition module, a data processing module, a control module, and an early warning communication module. The workshop information acquisition module collects data from within the child safety seat production workshop and transmits the collected information to the data processing module for analysis. If the data processing module analyzes abnormal equipment operation within the workshop, and if the abnormal equipment is a network-controlled device, it can be remotely controlled directly through the control module to shut down the equipment or restore it to normal operation. If the equipment cannot be remotely controlled, the early warning communication module notifies the operators in the child safety seat production workshop, who then manually resolve the fault.

[0046] In the early warning communication module, two states are set: one is abnormal (R1), and the other is normal (R2). The extracted feature values ​​of the target results from the seat installation production workshop are represented as follows: T = {t1, t2, ..., t12} represents the average detection rate mAP value; According to the conditional probability formula, given the eigenvalue T, the probability that a suspected anomaly is classified as R1 is: Where P(T|R1) represents the probability of the feature value T appearing in the abnormal subset of the sample set, and P(R1) represents the proportion of the abnormal subset in the entire sample set. Given an eigenvalue T, the probability of a suspected anomaly being classified as R2 is expressed as follows: Where P(T|R2) represents the probability of the feature value T appearing in the normal subset of the sample set, and P(R2) represents the proportion of the normal subset in the entire sample set; If P(R1|T) > P(R2|T), the monitored average detection rate mAP value is considered abnormal; otherwise, it is considered normal.

[0047] Working Principle: During the inspection of the safety seat production workshop, when the inspection robot needs to raise the acquisition camera 104, the drive motor 106 first drives the lead screw 105 to rotate, causing the lead screw 105 to move the lifting rod 103 upward. The lifting rod 103 then moves the acquisition camera 104 upward. When the lifting rod 103 first starts to move upward, it also drives the control rod 206 upward. Because a pair of clamping rods 210 are clamped outward on the side wall of the slide groove 202, the lifting rod 103 cannot initially move the support plate 203 upward. At this time, the lifting rod 103 can only move the control rod 206 upward. The control rod 206 pulls the clamping rods 210 inward into the support plate 203 through the connecting block 208 and a pair of rotating parts 209, causing the outer ends of the clamping rods 210 to release from the inner wall of the slide groove 202. Subsequently, the control rod 206 can then move the support plate 203 upward.

[0048] When the lifting rod 103 stops moving upward, the interaction of the elastic forces of a pair of elastic elements 215 pushes the control plate 214 upward. The control plate 214 then moves the control rod 206 downward back to its original position. This causes the control rod 206 to push a pair of clamping rods 210 outward from the support plate 203 via the connecting block 208 and a pair of rotating elements 209, clamping the outer ends of the clamping rods 210 against the inner wall of the slide groove 202, thereby fixing the bottom end of the support plate 203. At the same time, the elastic force of the elastic plate 216 pushes the locking head 217 into the locking groove 218, thereby preventing the control rod 206 from wobbling up and down, thus ensuring the stability of the support plate 203 and the control rod 206 in supporting the lifting rod 103.

[0049] Subsequently, the drive motor connected to the external drive shaft 307 drives the drive shaft 307 to rotate. The drive shaft 307 drives the drive belt 309 to rotate through the drive wheel 308, causing the drive belt 309 to drive the moving block 304 and the C-shaped moving part 305 to slide in opposite directions simultaneously, so that the moving block 304 and the C-shaped moving part 305 slide from one end of the inner groove 301 to the other end at the same time. The moving block 304 and the C-shaped moving part 305 are each driven by a pair of Z-shaped support rods 310 to drive the auxiliary wheel 312 to extend outward from the moving base 1. Then, through the upper top wall of the Z-shaped support rod 310, they fit against the bottom end of the side wall of the inner groove 301, thereby supporting the pair of auxiliary wheels 312 on the ground.

[0050] Therefore, a pair of support plates 203 provide auxiliary support for the lifting rod 103 after it is raised and lowered, and two pairs of Z-shaped support rods 310 drive two pairs of auxiliary wheels 312 to extend outward from the bottom of the movable base 1 and support it on the ground. This increases the support area between the movable base 1 and the ground, thereby improving the support stability of the movable base 1 and thus improving the accuracy of the information collection of the safety seat production workshop by this device.
