[0002] In high-risk industrial environments such as chemical plants, security checks on personnel entering and exiting the premises are a crucial step in ensuring production safety and preventing accidents. Previously, the commonly used infrastructure consisted of manual or semi-automatic access control gates combined with human checkpoints.

This method has the following problems: During peak working hours, manual inspections are slow and can easily cause queues and congestion at the factory entrance. The quality of manual inspections is highly dependent on the responsibility, experience, and condition of security personnel. Fatigue, negligence, or personal interference can lead to inconsistent application of inspection standards, resulting in missed or incorrect inspections, allowing prohibited items and unsafe personnel to enter the chemical plant area, creating potential safety hazards.

[0029] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0030] The present invention provides the following preferred embodiments: Example 1, as Figures 1-10 As shown, a self-service security check barrier gate for a chemical plant area includes a first channel 11, a second channel 12, and a third channel 13. The first channel 11, the second channel 12, and the third channel 13 are connected sequentially by multiple fasteners. A first gate 17, a second gate 48, and a third gate 49 are respectively installed inside the first channel 11, the second channel 12, and the third channel 13. Specifically, the first gate 17, the second gate 48, and the third gate 49 are all electric turnstiles in the prior art. An identity recognition mechanism is installed inside the first channel 11, a security recognition mechanism is installed inside the second channel 12, and a metal recognition mechanism is installed inside the third channel 13. By setting up identity recognition, security recognition, and metal recognition mechanisms, the corresponding gate can only be opened and passage can be achieved through the recognition mechanism. This allows the barrier gate to integrate multiple discrete security inspection steps with the passage frame, achieving streamlined inspection. It ensures that personnel must complete all inspection items in a predetermined order, reducing the possibility of missed or incorrect inspections due to human negligence. It also ensures that the inspection standards for each entrant are completely consistent, which is conducive to improving the safety factor of the chemical plant. By utilizing the first channel 11, the second channel 12, and the third channel 13, this barrier gate forms a semi-sealed integrated channel. Guiding personnel must pass through according to the set inspection sequence and path, and cannot skip or bypass any inspection links, further ensuring the rigid implementation of the security inspection system. The identification mechanism includes an access control card reader 18 and two support plates 50. By setting up the identification mechanism, it is possible to verify whether employees or visitors have valid credentials and confirm whether they are authorized to enter the area. The function of the access control card reader 18 is to verify the identity of the cardholder. Once the identity is verified, a signal is sent to the controller, which then controls the first gate 17 to open, allowing the person to pass through. Access control card reader 18 mainly includes an identity recognition module: reading card, password or biometric information; The access control module compares the read information with the system database to determine whether the person has access permissions during that time period. Output control module: After successful verification, it outputs a signal to the controller to enable the channel; Record storage: Records all access events (time, card number, success or failure, etc.) for auditing and traceability; The structure of the access control card reader 18 is existing technology and will not be described in detail here; The security identification mechanism includes a machine vision camera 28, a support component, and a rotating component. The machine vision camera 28 is located above one side of the second gate 48. The support component is fixed to the bottom of the second channel 12. The rotating component is mounted on the support component, and the machine vision camera 28 is fixed on the rotating component. By setting up the security identification mechanism, the machine vision camera 28 can detect whether the inspected person is wearing a safety helmet, protective clothing, or other specific protective clothing, which can improve the self-protection effect of personnel or visitors. The machine vision camera 28 detects whether a person is wearing the correct clothing by recognizing the image. Once the detection is successful, it sends a signal to the controller, which then controls the second gate 48 to open, allowing the person to pass through. The structure of the machine vision camera 28 is existing technology and will not be described in detail here; The metal detection mechanism includes two security probes 36, two swing mechanisms, and two lifting components. The two lifting components are symmetrically installed on both sides of the inner wall of the third channel 13. The two swing components are respectively installed at the ends of the two lifting components that are close to each other. The two security probes 36 are respectively installed on the two swing components. By setting up the metal detection mechanism, the security probes 36 can be used to conduct a full-body check on the inspected personnel to detect whether they are carrying prohibited items such as lighters, which helps to ensure the safety of the chemical plant area. The security inspection wrench 36 specifically adopts the handheld security inspection wrench of the existing technology. It can move along a set trajectory by using the swing component and the lifting component. The security inspection wrench 36 mainly includes a transmitting and receiving module: it contains a transmitting coil and a receiving coil; the transmitting coil is supplied with a high-frequency current to generate a high-frequency alternating magnetic field (detection magnetic field). Interference and alarm module: When the security probe 36 approaches a metal object, eddy currents are generated inside the metal; these eddy currents generate a new magnetic field, which in turn affects the original magnetic field of the detector. Signal processing module: The receiving coil captures this magnetic field change and transmits the signal to the built-in processing chip; the chip analyzes the intensity of the change, and if it does not exceed the preset sensitivity threshold, it sends a signal to the controller, which controls the third gate 49 to open, allowing workers to pass through; The structure of the security screening wrench 36 is existing technology and will not be described in detail here; Each detection and identification mechanism is installed inside a channel as an independent "functional detection box", and every two channels are detachably connected by fasteners, which facilitates production, transportation and rapid on-site assembly. If the detection and identification mechanism inside a single channel fails, it can be directly disassembled and replaced without affecting the overall operation.

[0031] like Figures 1-10 As shown, the support assembly includes a fixing ring 21, a fixing plate 22, and two mounting plates 23. The fixing ring 21 is located inside the second channel 12. The fixing plate 22 is fixed to the top of the fixing ring 21. The two mounting plates 23 are symmetrically fixed to the top two sides of the fixing plate 22. The other end of each mounting plate 23 is fixedly connected to the second channel 12. The fixing ring 21 can be fixedly installed inside the second channel 12 through the fixing plate 22 and the two mounting plates 23, which facilitates the installation of the machine vision camera 28 and the rotating assembly.

[0032] like Figures 1-10 As shown, the rotating assembly includes a first motor 24, a main shaft 25, a connecting plate 26, and a movable seat 27. The movable seat 27 is slidably mounted on the fixed ring 21, meaning that the movable seat 27 can move along the fixed ring 21. The main shaft 25 is rotatably mounted on the fixed plate 22 via bearings. One end of the connecting plate 26 is fixedly connected to the bottom end of the main shaft 25, and the other end of the connecting plate 26 is fixedly connected to the movable seat 27. The machine vision camera 28 is detachably mounted on the bottom end of the movable seat 27 for adjusting the mounting angle of the machine vision camera 28, and also for facilitating the replacement and maintenance of the machine vision camera 28. The first motor 24 is mounted on the fixed plate 22, and the output end of the first motor 24 is fixedly connected to the top end of the main shaft 25. When personnel enter the first detection area 19 inside the second channel 12, the first motor 24 is controlled to work. The first motor 24 can drive the main shaft 25 to rotate. When the main shaft 25 rotates, it can drive the moving seat 27 to move along the fixed ring 21 through the connecting plate 26, thereby driving the machine vision camera 28 to rotate one revolution to detect whether the personnel are wearing safety helmets, protective clothing or other specific protective clothing.

[0033] like Figures 1-10As shown, each swing mechanism includes an arc-shaped frame 31, an arc-shaped gear ring 32, a moving frame 33, a gear 34, and a second motor 35. The arc-shaped frame 31 is located inside the third channel 13, the arc-shaped gear ring 32 is fixedly installed on the outside of the arc-shaped frame 31, and the moving frame 33 is slidably mounted on the arc-shaped frame 31. Specifically, it should be noted that a dovetail groove is provided at the top of the arc-shaped frame 31, and a slider matching the shape of the dovetail groove is fixed at the bottom of the moving frame 33. The slider slides inside the dovetail groove, and the dovetail... The fit between the slot and the slider makes it difficult for the movable frame 33 to be removed from the arc frame 31, and the movable frame 33 can be raised and lowered synchronously when the arc frame 31 is raised and lowered. The gear 34 is located on one side of the arc gear ring 32 and is rotatably set at the bottom of the movable frame 33. The gear 34 and the arc gear ring 32 mesh with each other. The second motor 35 is installed on the side of the movable frame 33 away from the gear 34. The output end of the second motor 35 is fixedly connected to the gear 34. The security probe 36 is detachably installed on one side of the movable frame 33. When personnel enter the second detection area 29 inside the third channel 13, the two second motors 35 are controlled to operate. The second motors 35 drive the gears 34 to rotate. Since the gears 34 mesh with the arc-shaped gear ring 32, when the gears 34 rotate, they can drive the moving frame 33 to slide on the arc-shaped frame 31, thereby driving the security probes 36 to move. That is, each security probe 36 can move along the trajectory of the arc-shaped frame 31. By using the cooperation of the two security probes 36 and the lifting assembly, the entire body of the person being inspected can be checked to detect whether they are carrying prohibited items such as lighters, which helps to ensure the safety of the chemical plant area.

[0034] like Figures 1-10 As shown, each lifting assembly includes a U-shaped frame 38, a fixed seat 39, a lead screw 40, a motor seat 41, and a third motor 42. Each arc-shaped frame 31 has a limiting plate 37 fixed on both sides. The U-shaped frame 38 is located on one side of the arc-shaped frame 31 and its two ends are fixedly connected to the two limiting plates 37 respectively. The U-shaped frame 38 is slidably disposed on the inner wall of the third channel 13. The two ends of the lead screw 40 are rotatably connected to the bottom and top of the third channel 13 respectively. The motor seat 41 is installed at the top of the third channel 13. The third motor 42 is installed on the motor seat 41. The output end of the third motor 42 is fixedly connected to one end of the lead screw 40. The fixed seat 39 is installed on the lead screw 40 and is threadedly engaged with the lead screw 40. One side of the fixed seat 39 is fixedly connected to the surface of the U-shaped frame 38. When the security probe 36 needs to be moved up and down, the third motor 42 is controlled to work. The third motor 42 can drive the lead screw 40 to rotate. Since the lead screw 40 and the fixed seat 39 are threaded together, and the U-shaped frame 38 slides on the inner wall of the third channel 13, the rotation of the lead screw 40 can drive the U-shaped frame 38 to rise and fall, thereby driving the security probe 36 to rise and fall through the arc frame 31.

[0035] like Figures 1-10 As shown, two guide rods 44 are fixed on the inner walls of both sides of the third channel 13. Each guide rod 44 is slidably connected to a slide block 43. The two slide blocks 43 on the same side are fixed to the surface of a U-shaped frame 38. Through the sliding connection between the slide block 43 and the guide rod 44, the U-shaped frame 38 can be guided and limited.

[0036] like Figures 1-10 As shown, a first detection area 19 is provided on one side of the second gate 48. The first detection area 19 is installed at the bottom of the second channel 12. A first through-beam laser sensor 20 is provided above the first detection area 19. The first through-beam laser sensor 20 is installed on the inner walls of both sides of the second channel 12. When a person enters the first detection area 19, the first through-beam laser sensor 20 can detect that the person has reached the designated position. At this time, a signal can be sent to the controller, thereby controlling the security identification mechanism to work. A second detection area 29 is provided on one side of the third gate 49. The second detection area 29 is installed inside the third channel 13. A second through-beam laser sensor 30 is provided above the second detection area 29. The second through-beam laser sensor 30 is installed on the inner walls of both sides of the third channel 13. When a person enters the second detection area 29, the second through-beam laser sensor 30 can detect that the person has reached the designated position. At this time, a signal can be sent to the controller, thereby controlling the metal identification mechanism to achieve self-service detection.

[0037] like Figures 1-10 As shown, both support plates 50 are fixed to the top of one side of the first gate 17, and the access control card reader 18 is installed on the top of the two support plates 50. The support plates 50 are used to support and install the access control card reader 18.

[0038] like Figures 1-10 As shown, each fastener includes a bolt 46, a nut 47, and two mounting blocks 45. Each mounting block 45 has a mounting hole that mates with the bolt 46. The bolt 46 is located inside the two mounting holes, and the nut 47 is fitted on the outside of the bolt 46 and is threadedly engaged with the bolt 46. Specifically, bolts 46 are installed at the ends of the first channel 11 and the third channel 13 near the second channel 12, as well as at both ends of the second channel 12. When connecting adjacent channels, the connection can be achieved through the cooperation between the bolts 46 and nuts 47. That is, each pair of channels is detachably connected by fasteners, which facilitates production, transportation and rapid on-site assembly. If the detection and identification mechanism inside a single channel fails, it can be directly disassembled and replaced without affecting the overall operation.

[0039] like Figures 1-10As shown, guardrails 14 are fixedly installed on both sides of the end of the first passage 11 away from the third passage 13. The guardrails 14 can act as a barrier to ensure that personnel can only enter through this gate and that no inspection steps can be skipped or bypassed. A glass window 15 is embedded at the top of the first passage 11, the second passage 12 and the third passage 13 to allow light to pass through. Multiple ventilation openings 16 are opened on both sides of the first passage 11, the second passage 12 and the third passage 13 to allow ventilation.

[0040] The specific working process of this invention is as follows: During personnel screening, personnel first enter the interior of the first channel 11 and place their identity card on the access control card reader 18. The access control card reader 18 verifies the cardholder's identity. Once the identity is verified, a signal is sent to the controller, which controls the first gate 17 to open, allowing personnel to pass through. After personnel enter the first inspection area 19 inside the second channel 12, they control the first motor 24 to work. The first motor 24 can drive the main shaft 25 to rotate. When the main shaft 25 rotates, it can drive the moving seat 27 to move along the fixed ring 21 through the connecting plate 26, thereby driving the machine vision camera 28 to rotate one revolution to check whether the personnel are wearing safety helmets, protective clothing or other specific protective clothing. When the inspection is qualified, a signal will be sent to the controller, and the controller will control the second gate 48 to open to allow personnel to pass. After personnel enter the second detection area 29 inside the third channel 13, they control two second motors 35 to operate. The second motors 35 drive gears 34 to rotate. Because gears 34 mesh with the arc-shaped gear ring 32, when gears 34 rotate, they drive the moving frame 33 to slide on the arc-shaped frame 31, thereby moving the security probes 36. That is, each security probe 36 can move along the trajectory of the arc-shaped frame 31. Simultaneously, the third motor 42 is controlled to operate, driving the lead screw 40 to rotate. The screw 40 and the fixed seat 39 are threaded together, and the U-shaped frame 38 slides on the inner wall of the third channel 13. Therefore, when the screw 40 rotates, it can drive the U-shaped frame 38 to rise and fall, which in turn can drive the security bar 36 to rise and fall through the arc frame 31. By using the cooperation of the two security bars 36 and the lifting assembly, the whole body of the person being inspected can be inspected to detect whether they are carrying prohibited items such as lighters. When the inspection is qualified, the security bar 36 sends information to the controller, and the controller controls the third gate 49 to open so that the person can pass through. By utilizing the first channel 11, the second channel 12, and the third channel 13, this barrier gate forms a semi-sealed integrated channel. Guiding personnel must pass through according to the set inspection sequence and path, and cannot skip or bypass any inspection links, further ensuring the rigid implementation of the security inspection system.

[0041] The beneficial effects of the present invention are specifically reflected in the fact that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
