Description

Technical Field

[0001] This utility model relates to the field of gate technology, and in particular to a monitoring gate. Background Technology

[0002] Turnstiles (such as swing gates, wing gates, and tripod turnstiles) are widely used in subways, office buildings, residential communities, scenic spots, and other places where access needs to be controlled. Traditional turnstiles have a single function, mainly performing basic blocking and passage functions. Their monitoring capabilities are weak, usually requiring the installation of separate surveillance cameras, sensors, and other equipment, and they have the following disadvantages: (1) The system has low integration, complex installation and wiring, and high cost; (2) Each device works independently, with poor coordination, making it difficult to achieve efficient linkage control; (3) The function is limited and it is impossible to detect and warn the status of passers-by in real time (such as body temperature, whether they are wearing masks, carrying prohibited items, etc.); (4) Multiple devices are stacked in appearance, affecting aesthetics.

[0003] Therefore, there is an urgent need to provide a monitoring gate that can achieve efficient linkage control compared to existing technologies. Utility Model Content

[0022] The technical solution of this utility model will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are not all embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. It should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, this utility model provides a monitoring gate, including a monitoring gate mechanism 1. Through the highly integrated design of the monitoring gate mechanism 1, multiple monitoring and sensing functions are intelligently linked with the gate, solving the problems of single function and poor coordination in traditional solutions, and realizing safe, efficient and intelligent access management, which is convenient to use.

[0024] The monitoring gate mechanism 1 includes two sets of centrally symmetrically arranged chassis 11. Each chassis 11 has a mounting slot 12 on its side, inside which a main control board 13 is installed. A servo motor 14 is fixedly connected to the mounting slot 12. A storage slot 16 is provided on opposite sides of the two chassis 11. A swing arm 15 is fixedly connected to the inside of the storage slot 16, extending from the output end of the servo motor 14. The swing arm 15 is rotatably connected to the storage slot 16. A monitoring component 17 is located on the top side of each chassis 11. A signal receiver 18 is installed inside each chassis 11. The signal receiver 18 supports Wi-Fi, 4G / 5G, or Ethernet communication and is used to upload data such as gate status, passage records, and alarm information to the cloud or local management platform. It can also receive remote control commands (such as remote gate opening and parameter setting). An emergency switch 28 is installed on one side of the chassis 11. The emergency switch 28 is a physical button switch located in a prominent position on the side of the chassis 11. In an emergency (such as a power outage or system failure), pressing the emergency switch 28 can directly cut off the power supply to the servo motor 14 and, through a mechanical linkage device, the power supply to the swing arm 15. Under normal operating conditions, the servo motor 14 is connected to the transmission mechanism of the swing arm 15 through an electromagnetic clutch. When the emergency switch 28 is pressed, the power supply to the servo motor 14 is cut off at the same time as the power supply to the electromagnetic clutch. After the clutch loses power, it will automatically disengage, thereby disconnecting the drive connection between the servo motor 14 and the swing arm 15. In this way, the swing arm 15 loses the locking force of the motor and can be easily pushed open or swung freely by hand. The swing arm 15 is released to a free passage state to ensure the safe evacuation of personnel. The swing arm 15 is rotatably connected to the middle position of the inner wall of the storage slot 16. The size of the storage slot 16 is adapted to the swing arm 15, and the swing arm 15 can rotate left and right to be stored in the storage slot 16 for convenient use. A sealing plate 26 is provided on one side of the chassis 11. The sealing plate 26 is adapted to the mounting slot 12, and a fixing bolt 27 is provided inside the sealing plate 26. One end of the fixing bolt 27 extends to the side of the sealing plate 26 and is threaded to the chassis 11. The sealing plate 26 is fixed to the chassis 11 by the fixing bolt 27, which facilitates installation and maintenance and makes it easy to use.

[0025] The monitoring component 17 includes a face recognition camera 21, a display screen 22, a fill light 23, and an indicator light 24. The display screen 22 is fixedly connected to the top of the chassis 11. The face recognition camera 21 is located on the top side of the display screen 22, and the fill light 23 is located on the top side of the display screen 22. The fill lights 23 are symmetrically arranged on both sides of the two sets of face recognition cameras 21. The bottom of the display screen 22 is equipped with an indicator light 24. The face is scanned by the face recognition camera 21, and the face is displayed on the display screen 22. The fill light 23 provides light supplementation to complete the face recognition. The working status is displayed by the indicator light 24. It is easy to use. The fill light 23 located on the top of the display screen 22 is a visible light LED fill light, which is used to supplement the light during face recognition and assist the face recognition camera 21 in working in low light environments.

[0026] Multiple sets of through-beam infrared sensors 20 for transmitting and receiving signals are installed on both sides of the storage slot 16. The through-beam infrared sensors 20 are divided into a transmitting end and a receiving end. Personnel can be monitored through the through-beam infrared sensors 20. They are easy to use. Multiple sets of through-beam infrared sensors 20 are symmetrically arranged on both sides of the storage slot 16 to form an infrared beam array. When a person enters the detection area, part of the beam is blocked. The main control board 13 determines the presence of the person, the direction of movement, and whether the person is in a legal passage area based on the number and position of the blocked beams, thereby triggering the subsequent face recognition and body temperature detection process.

[0027] Both sets of chassis 11 have a multi-functional detector 25 fixedly connected to the top of their opposite sides for detecting metal and body temperature. The multi-functional detector 25 can monitor the body temperature of personnel and metal objects. It is easy to use. The multi-functional detector 25 integrates an infrared temperature measurement module and a metal detection module. The infrared temperature measurement module uses a non-contact infrared sensor (such as MLX90614) to calculate body temperature by detecting the infrared radiation emitted by the human body. The metal detection module is based on the principle of electromagnetic induction. When a metal object approaches, it causes a change in the electromagnetic field. The signal processing circuit determines whether there is a metal object. The two detection results are transmitted to the main control board 13 through serial communication.

[0028] The chassis 11 is equipped with a voice broadcast module 19, which can be used to broadcast voice messages. It is easy to use. The voice broadcast module 19 integrates an MP3 decoding chip and a speaker. The voice broadcast module 19 is used to broadcast various voice prompts, including "Please scan your face", "Normal body temperature" and "Please do not bring metal objects".

[0029] like Figure 5As shown, the main control board 13 uses an embedded microcontroller (such as the STM32 series or ARM Cortex-A series), which integrates an ADC module, GPIO interface, communication interface (such as UART, SPI, I2C) and motor drive circuit, a face recognition camera 21, a display screen 22, a fill light 23, an indicator light 24, the main control board 13, a signal receiver, an infrared temperature measurement module, a metal detection module, an MP3 decoding chip and a servo motor 14. The signal receiver is connected to the through-beam infrared sensor 20, and the speaker is connected to the MP3 decoding chip.

[0030] In use, the infrared sensor 20 senses the human body and transmits the data through the signal receiver 18. Simultaneously, the face recognition camera 21 scans the face, displays the face on the display screen 22, and supplements the light source with the auxiliary light 23 to complete the face recognition. The auxiliary light 23 on the side of the chassis 11 detects the body temperature and metal. After all monitoring is successful, the data is transmitted to the main control board 13. The main control board 13 controls the servo motor 14 to drive the swing arm 15 to rotate into the storage slot 16, thereby completing the passage of personnel. Through highly integrated design, multiple monitoring and sensing functions are intelligently linked with the gate, solving the problems of single function and poor coordination in traditional solutions. This achieves safe, efficient, and intelligent access management and is easy to use.

[0031] It should be noted that the main control board 13, servo motor 14, monitoring component 17, signal receiver 18, and multi-function detector 25 are existing devices, and their circuit connections, dimensions, and models are all existing technologies, so they will not be described in detail.

[0032] Finally, it should be noted that the above content is only used to illustrate the technical solution of this utility model, and is not intended to limit the scope of protection of this utility model. Simple modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model do not depart from the essence and scope of the technical solution of this utility model.
