Description

Technical Field

[0001] This utility model belongs to the field of radio frequency technology, and specifically relates to a gate safety door. Background Technology

[0002] In access control scenarios at venues such as libraries, turnstiles are commonly used to effectively detect whether readers are carrying books they haven't borrowed. Typically, these venues install one or more pairs of turnstiles, spaced apart to form detection channels, facilitating orderly entry and exit for readers. Each turnstile is equipped with a gate and an antenna, with the antenna playing a crucial role in information detection.

[0003] Specifically, the antenna on the turnstile continuously transmits read / write signals, using radio frequency identification (RFID) technology to detect the books carried by readers. When the system detects that a reader has borrowed a book, it opens the gate, allowing the reader to pass through the detection channel. Conversely, if the system detects that a reader has not borrowed a book, it keeps the gate closed, preventing the reader from passing through, thus ensuring the order of book management in the library.

[0004] However, existing turnstile systems have significant technical flaws in actual operation. When the antenna installed on the turnstile is in operation, it can become mutually coupled with the antennas of other turnstiles, causing severe interference to the read / write signals transmitted by the antenna and greatly affecting the detection of the reader's carrying of books. Specifically, this manifests as follows:

[0005] On the one hand, the read / write signals emitted by the working gate antenna will excite the inactive gate antenna, causing a resonant signal on the inactive gate antenna. These resonant signals will interfere with the normally operating read / write signals, damaging the stability and accuracy of the read / write signals, causing the system to be unable to accurately determine the borrowing status of the books carried by the reader.

[0006] On the other hand, the energy of the read / write signal emitted by a working gate antenna is dispersed and consumed during the process of stimulating a non-working gate antenna, weakening the signal strength. This reduced signal strength further affects the detection range and sensitivity of the read / write signal, lowering the reliability of the entire detection system and making it difficult to accurately detect readers carrying unborrowed books.

[0007] Therefore, the existing library turnstile system suffers from reading and writing signal interference caused by antenna mutual coupling, which severely restricts the normal functioning of its detection capabilities, and an effective technical solution is urgently needed to improve it. Utility Model Content

[0008] The primary objective of this invention is to solve at least one of the aforementioned problems by providing a gate safety door.

[0009] To achieve the various objectives of this utility model, the following technical solution is adopted:

[0010] To achieve one of the purposes of this utility model, a turnstile safety gate is provided, comprising a control component and at least one turnstile device. The turnstile device includes a pair of turnstiles and an antenna assembly. The pair of turnstiles are arranged at an interval relative to each other to form a turnstile channel. The turnstile includes a main body and a vertical plate arranged on the main body. The antenna assembly includes a pair of antennas, which are respectively disposed on the pair of vertical plates.

[0011] The antenna includes a loop coil and a control node. The loop coil has a physical gap forming an open circuit. The control node is bridged at both ends of the open circuit gap. The control component controls the on / off state of the control node to control the on / off state of the antenna.

[0012] In one embodiment, the turnstile security gate includes multiple turnstile devices arranged sequentially along the same axis. The control component controls the antenna assemblies of each of the multiple turnstile devices to operate in a time-division multiplexing manner. In the same time slot, the control component controls the control nodes of the two antennas of the antenna assembly of one of the turnstile devices to operate simultaneously.

[0013] In one embodiment, the control node is any one of a controller, an electronic switch, a radio frequency switch, or a switching circuit.

[0014] In one embodiment, the annular coil is arranged on the upright plate, and at least one of the two sides of the upright plate is covered with a shielding film.

[0015] In one embodiment, the turnstile safety gate includes multiple turnstile devices arranged sequentially along the same axis. The antenna assemblies of each of the multiple turnstile devices operate at different frequencies, and the two antennas of the same antenna assembly operate at the same frequency.

[0016] In one embodiment, the antenna includes a plurality of loop coils, each loop coil being configured with a control node.

[0017] In one embodiment, the turnstile further includes a motor and a gate. The gate is disposed on one side of the main body. The output shaft of the motor is drivenly connected to the gate. The two gates of the turnstile device are disposed opposite to each other. The control component synchronously controls the operation of the motors of each pair of gates of the turnstile device to control the opening / closing of the two gates.

[0018] In one embodiment, one of the turnstiles of the turnstile device is further provided with an infrared sensing module and / or a face recognition module, wherein the infrared sensing module is electrically connected to the face recognition module and the control component.

[0019] In one embodiment, the turnstile security gate includes multiple turnstile devices arranged sequentially along the same axis. In two adjacent turnstile devices, the right turnstile of one turnstile device shares the same main body with the left turnstile of the other turnstile device.

[0020] In one embodiment, a shielding plate is provided between the upright plate of the right gate and the upright plate of the left gate.

[0021] Compared with the prior art, this utility model has many advantages, including but not limited to:

[0022] In this utility model of a turnstile safety gate, the antenna has a physical gap formed by an interval on the loop coil, and the control node is bridged at both ends of the gap. The control node has an on / off control function, and its on / off state can be precisely controlled by the control components, which can flexibly and effectively regulate the structural integrity of the loop coil.

[0023] In existing turnstile safety gates, multiple antennas typically operate simultaneously. Mutual coupling interference can severely affect the normal operation of the antennas, leading to signal distortion and inaccurate detection. In this invention, when the control node is in an open-circuit state, the continuous structure of the loop coil is disrupted, forming an open circuit. In this state, read / write signals from other antennas cannot effectively excite the loop coil, thus preventing it from generating a resonant signal. This cleverly avoids the mutual coupling interference caused by signal excitation between different antennas. Attached Figure Description

[0028] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model and should not be construed as limiting this utility model.

[0030] It will be understood by those skilled in the art that, unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. It should also be understood that terms such as those defined in general dictionaries should be understood to have the same meaning as in the context of the prior art, and should not be interpreted in an idealized or overly formal sense unless specifically defined as herein.

[0031] This utility model provides a turnstile safety gate. In this turnstile safety gate, when the antenna of any one of the turnstile devices is in working state, the antennas of the other turnstile devices are in non-working state. Furthermore, the control node on the coil of the antenna in non-working state is set to be open circuit, thereby destroying the integrity of the coil and preventing the coil from resonating due to the signal emitted by the antenna in working state, thus avoiding the generation of interference signals.

[0032] In a typical embodiment of this utility model, combined with Figure 1 and Figure 2 The turnstile safety gate 10 includes a control component 100 and at least one turnstile device 200, wherein the control component 100 and the turnstile device 200 interact via an electrical connection, and the control component 100 is configured to control the operation of the turnstile device 200.

[0033] Specifically, the turnstile device 200 includes a pair of turnstiles 210 arranged opposite each other and spaced apart, forming a turnstile channel 240 for the passage of personnel or objects. Each turnstile 210 includes a main body 211 and a gate 212 disposed on the side of the main body 211. A motor 213 is also disposed inside the main body 211, and the motor 213 is drivenly connected to the gate 212. The control component 100 establishes an electrical connection with the motor 213 and can send control signals to the motor 213 to drive the motor 213 to work, thereby driving the gate 212 to rotate relative to the main body 211, realizing the opening and closing action of the gate 212. In this embodiment, the output shaft of the motor 213 is directly connected to the gate 212. Thus, the control component 100 can precisely control the rotation angle of the motor 213 to achieve precise control of the opening and closing degree of the gate 212.

[0034] In this embodiment, the control component 100 can simultaneously control the motors 213 of each of the pair of turnstiles 210 in the turnstile device 200 to operate synchronously. Through this synchronous control method, the gates 212 of the pair of turnstiles 210 can move relative to each other. That is, when it is necessary to close the turnstile channel 240, the two gates 212 are controlled to close relative to each other, thereby closing the turnstile channel 240; when it is necessary to open the turnstile channel 240, the two gates 212 are controlled to open relative to each other, so that the turnstile channel 240 is in a free-flowing state.

[0035] In a typical embodiment of this utility model, the gate 210 further includes a vertical plate 220, which is vertically mounted on the main body 211 of the gate 210. The gate device 200 is also equipped with an antenna assembly, which includes a pair of antennas 230. These antennas 230 are respectively mounted on the vertical plates 220 of the two gates 210, meaning that each vertical plate 220 of each gate 210 independently has one antenna 230 mounted on it. Each antenna 230 is composed of one or more loop coils 231. In this embodiment, the utility model is described using the example of an antenna 230 comprising a loop coil 231, but this should not be construed as a limitation of the utility model. The control component 100 transmits signals to the pair of antennas 230 via an electrical connection and can control the operating state of the pair of antennas 230.

[0036] In this embodiment, the present invention is illustrated using the application scenario of deploying the turnstile security door 10 at the entrance and exit of a library as an example. However, this application scenario is only presented as an example and should not be regarded as any limitation on the scope of protection of the present invention.

[0037] Normally, readers need to complete the borrowing procedures inside the library before they can take the books out. To effectively check whether readers have completed the book borrowing process in accordance with regulations and to prevent book theft, library staff will install the aforementioned turnstile security gate 10 at the library's entrances and exits.

[0038] Specifically, the control component 100 of the turnstile security gate 10 controls the antenna 230 of each gate 210 on the turnstile device 200 to continuously transmit read / write signals. When a reader passes through the turnstile security gate 10 carrying a book with an RFID tag, the RFID tag on the book responds to the read / write signal transmitted by the antenna 230 and returns a response signal to the antenna 230. This response signal contains book information and borrowing information. After receiving the response signal returned by the RFID tag, the antenna 230 immediately uploads the signal to the control component 100. After receiving the response signal, the control component 100 parses and processes it to extract the corresponding book information and borrowing information.

[0039] If the parsed borrowing information indicates that the relevant book has been borrowed, the control component 100 will send a control command to the gate device 200 where the reader is located to open the gate channel 240, allowing the reader to pass through smoothly. Conversely, if the parsed borrowing information indicates that the book has not been borrowed, the control component 100 will control the gate device 200 where the reader is located to keep the gate channel 240 closed, preventing the reader from passing through, and at the same time trigger the alarm component to issue an alarm signal, thereby maintaining the normal book management order of the library.

[0040] In a typical embodiment of this utility model, the turnstile security gate 10 includes a plurality of turnstile devices 200, which are arranged in an orderly manner along the same axis. Each turnstile device 200 independently forms a turnstile channel 240. Based on this layout, multiple turnstile devices 200 can correspondingly construct multiple turnstile channels 240, thereby effectively increasing the number of entrances and exits and significantly improving the efficiency of personnel or objects entering and exiting.

[0041] Since each turnstile 200 is equipped with its own antenna assembly, to prevent mutual interference between the antenna assemblies of different turnstile 200 during operation and affecting the normal operation of the equipment, the control component 100 adopts a time-division multiplexing control strategy to schedule the operation of the antenna assemblies of the multiple turnstile 200. Specifically, in any given time slot, only one antenna assembly is in the working state, while the rest are in the non-working state. Through this time-division multiplexing working mode, the signal mutual interference problem caused by multiple antenna assemblies working simultaneously can be effectively avoided, ensuring the stable and reliable operation of the turnstile safety gate 10.

[0042] In this embodiment, combined with Figure 3 The antenna 230 includes a loop coil 231 and a control node 232. Specifically, the loop coil 231 has a break-circuit gap formed by physical spacing. This break-circuit gap is designed to disrupt the inherent continuity of the loop coil 231, making it a non-closed electrical circuit. When a read / write signal is radiated to the loop coil 231, due to the aforementioned break-circuit gap, the loop coil 231 cannot be effectively excited by external signals to generate a resonant signal. This effectively avoids mutual coupling between the antennas 230, thereby significantly improving the electrical performance and signal transmission stability of the gate safety door 10.

[0043] The control node 232 is located at the open circuit gap of the loop coil 231 of the antenna 230. Its main function is to act as an electronic switch, bridging the two ends of the open circuit gap to achieve flexible control over the on / off state of the loop coil 231. The control component 100 and the control node 232 establish a signal transmission path through an electrical connection. The control component 100 can send control commands to the control node 232 to control the control node 232 to be in a conducting or disconnected working state.

[0044] Regarding the specific implementation of control node 232, it is recommended to use any electronic component or circuit with switching function, such as a controller, electronic switch, radio frequency switch, or switching circuit. In this embodiment, for ease of explanation, control node 232 is described as an electronic switch, but it should be clarified that this example does not constitute any limitation on the scope of protection of this utility model.

[0045] In actual working scenarios, when the control component 100 sends a conduction control command to the corresponding control node 232 according to the preset working logic or received external instructions, the control node 232 will respond to the command and electrically connect the preset open circuit gap on the loop coil 231, so that the loop coil 231 becomes a closed loop and achieves conduction. In this closed conduction state, the loop coil 231 has the ability to transmit read and write signals to the outside, and thus can conduct stable and reliable communication interaction with the RFID tag to complete data read and write operations.

[0046] Conversely, when the control component 100 sends a disconnect control command to the corresponding control node 232, the control node 232 will, according to the command, not perform the connection operation on the open circuit gap of the loop coil 231, maintaining the original non-closed state of the loop coil 231. When the loop coil 231 is in the non-closed state, it cannot transmit any signals to the outside, nor will it be excited by external signals to generate resonant signals. This effectively avoids the mutual coupling phenomenon caused by the mutual influence of signals between different antennas 230, ensuring the accuracy and stability of the overall signal transmission of the gate safety door 10, and improving the working performance and reliability of the equipment.

[0047] Based on this, given that the control component 100 employs a time-division multiplexing control strategy, it precisely regulates the operating state of the antenna components equipped in each of the multiple gate devices 200. Within each specific time slot, the control component 100 sends a conduction command to the control nodes 232 corresponding to the two antennas 230 of an antenna component that is in operation. Correspondingly, these control nodes 232 respond to the command by electrically connecting the open circuits on the loop coils 231 of their respective antennas 230, ensuring that both antennas 230 in operation form closed loops, thereby enabling them to transmit read / write signals and achieve normal communication with devices such as RFID tags.

[0048] Meanwhile, for the remaining antenna components that are not in operation, the control component 100 sends a disconnect command to the control node 232 of their respective antennas 230. These control nodes 232, according to the command, maintain the disconnected state of the open circuit gap on the loop coil 231 of their respective antennas 230, causing the multiple antennas 230 in the non-operating state to be unable to form a closed loop. Since the antennas 230 in the non-closed loop cannot be effectively excited by external signals, the read / write signals sent by the antennas 230 in the operating state cannot cause these antennas 230 that cannot form a closed loop to generate resonant signals. This effectively avoids interference caused by mutual signal influence between different antenna components, significantly improving the communication performance of the gate security door 10. Furthermore, it avoids the signal attenuation problem caused by the mutual coupling effect between antennas 230 during transmission of the read / write signals sent by the antennas 230 in the operating state, ensuring that the read / write signals can be transmitted with high strength and accuracy, thereby improving the overall communication efficiency of the gate security door 10.

[0049] In one embodiment, at least one of the front and back surfaces of the upright plate 220 is covered with a shielding film (not shown). Given the arrangement of multiple turnstile devices 200 sequentially along the same axis, each turnstile device 200 is independently equipped with an antenna assembly. During operation, the antenna assembly generates an alternating electromagnetic field in its surrounding area, which is used to excite RFID tags affixed to objects such as books to achieve data interaction. However, without effective shielding measures, the electromagnetic fields generated by the channel antennas 230 of adjacent turnstile devices 200 will severely overlap, leading to mutual interference and affecting the normal communication and detection performance of the equipment.

[0050] By covering the upright plate 220 with a shielding film, a "Faraday cage"-like effect can be formed inside the turnstile channel 240 of this turnstile device 200. Specifically, the shielding film can confine the electromagnetic field generated by the antenna assembly within the turnstile channel 240 to the internal space of the turnstile channel 240 as much as possible, effectively preventing its outward diffusion. At the same time, the shielding film can also block the electromagnetic fields generated by adjacent turnstile devices 200, preventing them from entering the turnstile channel 240, thereby reducing the mutual interference of electromagnetic fields between different turnstile devices 200.

[0051] Furthermore, the shielding film possesses the characteristic of reflecting electromagnetic wave energy. Electromagnetic wave energy that would normally dissipate outside the turnstile channel 240 is reflected and guided to the effective detection area in the center of the turnstile channel 240 by the shielding film. This process is equivalent to concentrating the electromagnetic wave energy without increasing the transmission power of the antenna 230, thereby enhancing the field strength in the central area of ​​the turnstile channel 240. This enhanced field strength makes the turnstile device 200 more sensitive and reliable in reading book tags, improving the overall detection performance and stability of the equipment.

[0052] In one embodiment, since each gate device 200 is independently equipped with an antenna assembly, in order to effectively avoid signal interference between the antenna assemblies of different gate devices 200 and thus ensure the stability and reliability of the gate safety door 10 communication, the operating frequency of each antenna assembly is specifically set.

[0053] Specifically, different antenna components are configured to operate at different frequencies, while the two antennas 230 within the same antenna component are configured to operate at the same frequency. This frequency allocation method prevents signal interference between different antenna components due to frequency overlap; simultaneously, the two antennas 230 within the same antenna component operating at the same frequency can work collaboratively to achieve communication. This effectively avoids mutual interference between different antenna components, significantly improving the communication performance of the gate safety door 10.

[0054] In one embodiment, combined Figure 1 The gate 210 has a mounting slot 221 on its upright plate 220. Specifically, the mounting slot 221 is specifically designed for mounting the loop coil 231 of the antenna 230, and its location is positioned in a suitable area of ​​the upright plate 220.

[0055] The loop coil 231 of the antenna 230 is installed in the mounting slot 221. The extension path of the mounting slot 221 is completely consistent with the extension path of the loop coil 231, enabling precise matching between the loop coil 231 and the mounting slot 221. This allows the loop coil 231 to be smoothly, securely, and well embedded in the mounting slot 221, ensuring accurate positioning and reliable fixation after installation. Improper installation will not cause loosening or displacement, thus guaranteeing the normal and stable operation of the antenna assembly and improving the overall performance and reliability of the gate safety door 10.

[0056] In one embodiment, combined Figure 1 The turnstile safety gate 10 includes multiple turnstile devices 200, which are arranged sequentially along the same axis. For ease of description, the two turnstiles 210 included in each turnstile device 200 are defined as the left turnstile 251 and the right turnstile 252, respectively. The left turnstile 251 is fixedly located to the left of the right turnstile 252, and the right turnstile 252 is fixedly located to the right of the left turnstile 251.

[0057] In two adjacent turnstile devices 200, the right turnstile 252 of one turnstile device 200 (referred to as the first turnstile 253) and the left turnstile 251 of the other turnstile device 200 (referred to as the second turnstile 254) are arranged adjacent to each other. The first turnstile 253 and the second turnstile 254 are structurally integrated to form a common turnstile 255. Specifically, the first turnstile 253 and the second turnstile 254 share the same main body 211, realizing the intensive use of resources. At the same time, the gates of the first turnstile 253 and the second turnstile 254 are respectively set on the left and right sides of the main body 211. While satisfying the normal passage control function of the turnstile safety gate 10, it effectively saves the installation space of the turnstile safety gate 10, provides favorable conditions for the miniaturization of the turnstile safety gate 10, and improves the flexibility and applicability of the turnstile safety gate 10 in terms of spatial layout.

[0058] In a further embodiment, a shielding plate 256 is provided between the upright plate of the first gate 253 (referred to as the first upright plate 2531) and the upright plate of the second gate 254 (referred to as the second upright plate 2541). The shielding plate 256 reduces the mutual coupling between the antenna on the first upright plate 2531 and the antenna on the second upright plate 2541, thereby improving the communication performance of the gate safety door 10.

[0059] In one embodiment, the antenna 230 located on the stand plate 220 has a plurality of loop coils 231. Specifically, the antenna 230 includes several independent and isolated loop coils 231, which are integrated in a predetermined arrangement at a preset position on the stand plate 220 to achieve a specific electromagnetic field distribution and signal detection function.

[0060] The control component 100 has the capability to precisely control multiple loop coils 231 in the antenna 230. During actual operation, the control component 100 sequentially and orderly controls each loop coil 231 in the antenna 230 according to a pre-set polling strategy. Specifically, the polling method can be to activate the loop coils 231 sequentially according to their numerical order, or to switch the operating loop coils 231 based on a predetermined time interval or signal triggering condition.

[0061] By controlling the multiple loop coils 231 of the antenna 230 to work in a polling manner through the control component 100, the antenna 230 can use different loop coils 231 as the main working unit at different time periods, thereby changing the electromagnetic field distribution characteristics of the antenna 230. This dynamic change in electromagnetic field can effectively cover the detection blind spots that may exist when a traditional single loop coil is working, ensuring more comprehensive and accurate signal detection throughout the entire detection area, and greatly improving the detection performance and reliability of the gate safety door 10.

[0062] In one embodiment, combined Figure 2 The turnstile device 200 also includes an infrared sensing module. This infrared sensing module is installed on the main body 211 of one of the turnstiles 210 of the turnstile device 200 to ensure that it can effectively sense changes in the surrounding environment.

[0063] The control component 100 is electrically connected to the infrared sensing module, forming a stable and reliable signal transmission channel. During operation, when a user approaches the gate device 200, the infrared sensing module uses its built-in infrared sensing technology to detect changes in infrared radiation in the surrounding environment in real time. Once a user approach signal that meets preset conditions is detected, the infrared sensing module immediately generates a corresponding infrared sensing signal.

[0064] Subsequently, the infrared sensing module uploads the generated infrared sensing signal to the control component 100. After receiving the infrared sensing signal, the control component 100 issues start-up commands to each gate device 200 in the turnstile safety gate 10 according to the preset control logic and program, thereby controlling each gate device 200 to enter the working state and realizing the automated operation and intelligent management of the turnstile safety gate 10.

[0065] In one embodiment, combined Figure 1 and Figure 2 The gate device 200 is also equipped with a face recognition module 262. The face recognition module 262 is installed at a suitable position on the surface of the main body 211 of one of the gates 210 included in the gate device 200. This position needs to facilitate clear capture of the user's facial image to ensure the accuracy and reliability of the face recognition function.

[0066] The control component 100 is electrically connected to the face recognition module 262, establishing a stable data transmission channel. When a user approaches the gate device 200 and enters the effective recognition range of the face recognition module 262, the face recognition module 262 immediately starts working, using its built-in high-precision image acquisition and recognition technology to quickly acquire the user's facial data.

[0067] After acquiring the facial data, the facial recognition module 262 uploads the data to the control component 100 in real time. Upon receiving the facial data, the control component 100 uses pre-stored algorithms and databases to perform in-depth analysis and comparison processing on the facial data, thereby obtaining user data corresponding to the facial data. This user data may include user identity information, permission information, borrowing records, etc.

[0068] Based on the acquired user data, the control component 100 has two control modes. First, the control component 100 can determine whether a user has access permissions based on the permission information in the user data. If the user has valid access permissions, the control component 100 will send a control command to the drive mechanism of the gate device 200 to open the gate channel 240, allowing the user to pass through, thus achieving automated channel management. Second, in specific application scenarios such as libraries, the control component 100 can automatically bind the user's book borrowing operation data with the user's identity information based on the user data. Specifically, when a user borrows a book, the control component 100 associates and stores the relevant borrowing information (such as book number, borrowing time, etc.) with the acquired user data, thereby completing the automated book borrowing process, greatly improving the efficiency and accuracy of the book borrowing operation, and enhancing the user experience.

[0069] In summary, in the safety gate provided by this utility model, a control node is bridged at the open circuit gap of the ring coil. This control node has an on / off control function, and by precisely controlling its on / off state, it can effectively regulate the structural integrity of the ring coil. When the control node is in an open circuit state, the original continuous structure of the ring coil is destroyed, forming an open circuit. Under this condition, the read / write signals emitted by other antennas cannot effectively excite the ring coil, preventing it from generating a resonant signal. This cleverly avoids the mutual coupling interference phenomenon caused by the mutual excitation of signals between different antennas, effectively improving the independence and stability of the operation of each antenna component in the safety gate, thereby enhancing the communication performance and detection accuracy of the entire safety gate, and providing a solid guarantee for the reliable operation of the safety gate in complex electromagnetic environments.

[0070] The above description is merely a preferred embodiment of this utility model and an explanation of the technical principles employed.
