Description

Technical Field

[0001] This invention generally relates to the field of monitoring equipment, and specifically to a biosafety intelligent identification and monitoring device. Background Technology

[0002] In the field of biosafety, biological samples are typically stored in dedicated biosafety containers. To prevent unauthorized access, loss, or damage to samples, real-time monitoring and management of the container's door status and operator identity are required through intelligent biosafety identification and monitoring devices. In existing technologies, such monitoring devices are often fixed to the side wall of the biosafety container's door via a detachable mounting structure. Internally, they integrate a microwave radar sensing module—the core component that switches the device from a silent state to a working state. This module works by emitting a 2.4GHz microwave signal and receiving reflected signals from the human body. Upon detecting a person's approach, it triggers the device to switch from a low-power silent state to a working state, thereby activating functions such as door monitoring and RFID authentication.

[0003] However, existing biosafety intelligent identification and monitoring devices have flaws in their installation methods for microwave radar sensing modules in practical applications: to simplify the structure, the microwave radar sensing module is usually directly fixed inside the device housing, and the sensing direction of the module cannot be effectively adjusted. Since the human movement areas in biosafety containers are diverse, the fixedly installed microwave radar sensing module can only detect a preset single-direction area. When the human movement area deviates from this preset direction, the module cannot effectively receive the reflected microwave signals, leading to a misjudgment of "human approach," and consequently, failing to promptly trigger the device to switch from a silent state to an active state.

[0004] This defect directly affects the core function of the monitoring device: if an operator approaches the biological container in a non-preset walking area and performs the opening action, the access control monitoring module and identity verification module cannot be activated synchronously because the device is still in a silent state. Not only can the opening operation and the operator's identity not be recorded, but the opportunity to warn of illegal opening behavior may also be missed because the alarm module is not ready. At the same time, frequent "identification failures" require the operator to deliberately adjust the approach position, which reduces the practicality and convenience, and also weakens the safety monitoring effect of the biological container. Summary of the Invention

[0005] In view of the problems existing in the prior art, the present invention provides a biosafety intelligent identification and monitoring device, comprising: a main housing; a protruding post, one end of which is fixed to the bottom wall of the main housing, and the other end of which is provided with a threaded hole for mounting and screwing; an adjustment plate, which is an arc-shaped plate body with a cross-shaped sliding groove on it; a mounting plate, which is fixed to the edge of the adjustment plate for fixing to a circuit board or chip; and a fixing bolt, which passes through the sliding groove and is threaded into the threaded hole of the protruding post.

[0006] With the above-mentioned technical features, the staff can adjust the support state of the adjustment plate by fixing bolts in the sliding area of ​​the slide, which further realizes the circuit board adjustment operation and changes the orientation area of ​​the microwave radar sensing module. This makes it easier for the microwave radar sensing module to cover the door opening personnel without changing the fixed position of the main shell, thus improving the trigger success rate.

[0007] Moreover, the protrusions allow for a larger space between the circuit board and the inner wall of the main housing, which is beneficial for heat dissipation of the chips on the circuit board.

[0008] In some embodiments, the device further includes a pressure plate, which is an annular sheet structure and passes through the fixing bolt. Thus, the pressure plate increases the contact range between the fixing bolt and the adjusting plate, thereby increasing the stability of the adjusting plate's fixation.

[0009] In some embodiments, the system further includes a circuit board fixed to the side of the mounting plate opposite to the protruding post; a processor fixed to one side of the circuit board; a magnetic reed switch fixed to one side of the circuit board and electrically connected to the processor; and a magnetic post located to one side of the magnetic reed switch for monitoring the opening and closing status of the door. Thus, the opening and closing of the door causes the magnetic post to move closer to or further away from the magnetic reed switch, further enabling the switching of the internal circuitry of the magnetic reed switch, and transmitting the switching signal to the processor to determine the opening and closing status of the door.

[0010] In some embodiments, a secondary housing is further included, which is fixed to one side of the door and located next to the main housing, with the magnetic post fixed inside the secondary housing. Thus, the secondary housing increases the contact area between the magnetic post and the door, improving the stability of the fixation to the door. Similarly, the secondary housing also provides protection and enclosure for the magnetic post, ensuring the stability of the door opening and closing signal transmission.

[0011] In some embodiments, a limiting support plate protrudes along the length of the sub-shell, and the magnetic column is supported on one side of the limiting support plate. Thus, the limiting support plate provides support and limits the magnetic column, restricting its sliding within the sub-shell and improving the stability of the fixation between the magnetic column and the sub-shell.

[0012] In some embodiments, the end of the limiting support plate is provided with an arc-shaped deformation zone, the edge of which is flush with the edge of the sub-shell. This increases the contact area with the magnetic post, ensuring the stability of the magnetic post within the sub-shell. Furthermore, when the sub-shell cover is closed, the deformation zone also provides good support, improving the integrity of the sub-shell.

[0013] In some embodiments, the circuit board is further provided with a network communication module, which is electrically connected to the processor. This allows the door opening and closing information to be transmitted to the cloud, and related data to be remotely compared and processed.

[0014] In some embodiments, a read / write card chip is fixed inside the main housing and electrically connected to the processor. This allows for the identification and comparison of the identity information of the person opening and closing the door, and the transmission of this identity information to the cloud for comparison and feedback via a network communication module.

[0015] In some embodiments, an alarm is also fixed on the circuit board and electrically connected to the network communication module. Thus, the identity information of the cardholder is compared with information in the cloud. If the card-swipe information and the cloud information do not match, a signal to activate the alarm will be sent through the network communication module.

[0016] It should be understood that the description in the Summary of the Invention is not intended to limit the key or essential features of the embodiments of this disclosure, nor is it intended to restrict the scope of this disclosure. Other features of this disclosure will become readily apparent from the following description. Attached Figure Description

[0024] The preferred embodiments (or implementation methods) of the present invention will now be described in detail with reference to the accompanying drawings.

[0025] The following is for reference. Figures 1-5 This invention describes a biosafety intelligent identification and monitoring device.

[0026] Figure 1 A schematic diagram of the overall structure of a biosafety intelligent identification and monitoring device according to an embodiment of this utility model is shown. (Reference) Figure 1 As shown, this embodiment provides a biosafety intelligent identification and monitoring device, including a main body 11 and accessories 12 used in conjunction with the main body 11. The main body 11 and accessories 12 are mainly installed in the opening and closing area of ​​the biosafety container door. More specifically, the main body 11 is fixed to the opening and closing side of the biosafety container, while the accessories 12 are fixed to one side of the door in the opening and closing area of ​​the biosafety container. During the opening and closing process of the biosafety container, the accessories 12 move away from the main body 11, thereby realizing the recording and transmission of relevant information such as opening and closing information and personnel information.

[0027] Figure 2 This diagram illustrates the protective structure of the main body 11 in a biosafety intelligent identification and monitoring device according to an embodiment of the present invention. (See reference) Figure 2 As shown, the main body 11 of the device includes a main housing 21, a main cover 22 is detachably and fixedly connected to one side of the main housing 21, at least one circuit board 4 is installed inside the main housing 21, and a fixing structure for the circuit board 4 is provided on the bottom wall of the main housing 21.

[0028] Figure 3 An exploded view of the internal fixing structure of the main housing 21 in a biosafety intelligent identification and monitoring device according to an embodiment of this utility model is shown. (Reference) Figure 3As shown, specifically, a protruding post 23 is fixed to the bottom surface of the main housing 21, and the overall height of the protruding post 23 is between 3mm and 8mm. An arc-shaped adjusting plate 24 is provided above the protruding post 23. A cross-shaped groove 241 is opened in the middle area of ​​the adjusting plate 24, through which the adjusting plate 24 is penetrated. A fixing bolt 25 can be provided in the area of ​​the groove 241. The adjusting plate 24 and the protruding post 23 are fixed to each other by the insertion of the fixing bolt 25. A ring-shaped mounting plate 26 is horizontally provided on the edge area of ​​the adjusting plate 24, which can serve as a fixing carrier for the circuit board 4, increasing the stability of the fixing of the circuit board 4 and the adjusting plate 24.

[0029] Furthermore, to increase the stability of the connection between the adjusting plate 24 and the protrusion 23, a ring-shaped pressure plate 27 is also provided through the fixing bolt 25. The pressure plate 27 can be made of flexible rubber or a thin, deformable metal sheet. When the fixing bolt 25 is turned, the pressure plate 27 abuts against the bottom wall of the adjusting plate 24 and undergoes elastic deformation, indirectly increasing the contact area between the fixing bolt 25 and the adjusting plate 24, and further increasing the fixing stability of the adjusting plate 24 and the protrusion 23.

[0030] Moreover, with the joint support of the protruding post 23 and the adjusting plate 24, the free area around the circuit board 4 is greatly increased, which is conducive to improving the heat dissipation efficiency of the electrical components on the circuit board 4. Furthermore, the external stress applied to the main housing 21 by the external environment is not easily transmitted directly to the circuit board 4, thereby ensuring the stability and safety of the circuit board 4.

[0031] Figure 4 A circuit system diagram of a biosafety intelligent identification and monitoring device according to an embodiment of the present invention is shown. (Reference) Figure 4 As shown, this device can have one or multiple circuit boards 4, depending on the internal space of the main housing 21. In this embodiment, a processor 41 is mounted on the circuit board 4. The processor 41 can be a high-performance Arm Cortex-M4 chip, which integrates a network communication module 42 to enable remote wireless communication. Furthermore, it incorporates a powerful ultra-low-power radio solution that conforms to the LPWAN standard, enabling LoRa wireless communication.

[0032] A microwave radar sensing module 43 is also provided on the circuit board 4. This module can be a low-power 2.4GHz version to reduce power consumption. The microwave radar sensing module 43 is fixed to the circuit board 4 and electrically connected to the processor 41. In some embodiments, the microwave radar sensing module 43 can be fixed to a separate circuit board 4 and electrically connected to the processor 41 via wiring. The independent placement of the microwave radar sensing module 43 reduces the overall area of ​​the circuit board 4. When fixed to the mounting plate 26, it increases the rotation range of the adjustment plate 24 within the device body 11, allowing the emission area of ​​the microwave radar sensing module 43 to be more directly facing the area where the door is being opened or closed, improving the efficiency of human body recognition and further enhancing the efficiency of switching the device from a silent state to a working state.

[0033] Although the microwave radar sensing module 43 is fixed inside the main housing 21, both the main housing 21 and the main cover 22 of the main body 11 of the device are made of wave-transparent materials, such as ABS, to ensure that microwave signals can be transmitted and received normally, and to realize the function of detecting human proximity.

[0034] A card reader / writer chip 44 is also fixed on circuit board 4. The card reader / writer chip 44 is based on the 13.56MHz contactless chip RC522, which is electrically connected to the processor 41. When a person needs to open the door, by swiping the card, the person's identity information in the IC card can be uploaded to the cloud platform through the network communication module 42 and compared with the personnel information stored in the cloud platform to verify the person's information for opening and closing the door, and the mutual time information of the door opening and closing is recorded and archived. Due to the setting of the microwave radar sensing module, it can prioritize the identification of human bodies and switch working states, which can improve the reading efficiency and information transmission efficiency of IC cards.

[0035] An alarm 45 is also fixed on the circuit board 4. The alarm 45 can be a common audible and visual alarm 45, which is electrically connected to the processor 41. After a person swipes their card, the identity information of the IC card can be transmitted to the cloud. If the identity information does not match the information in the cloud, an alarm signal will be sent to the processor 41, causing the alarm 45 to sound an audible and visual alarm.

[0036] A magnetic reed switch 46 is also fixed on the circuit board 4. The magnetic reed switch 46 is located in the side area near the main housing 21 and is electrically connected to the processor 41. It mainly works in conjunction with the magnetic post 47 in the accessory 12. By moving the magnetic post 47 away from or closer to the magnetic post, the magnetic sheet inside the magnetic reed switch 46 is displaced, thereby sending a circuit-opening or circuit-breaking signal to the processor 41.

[0037] The main housing 21 is also equipped with a power module 48. The power module 48 can be a rechargeable battery or a removable and replaceable dry cell battery. The power module 48 is electrically connected to the circuit board 4 to supply power to the electrical components of the circuit board 4.

[0038] Figure 5 An exploded view of component 12 in a biosafety intelligent identification and monitoring device according to an embodiment of this utility model is shown. (Reference) Figure 5 As shown, accessory 12 mainly includes a secondary housing 31 and a secondary cover 32 that is detachably and fixedly connected to the open end of the secondary housing 31. The secondary housing 31 is mainly a long strip structure, which is mainly located in the area near the magnetic reed switch 46 inside the main housing 21, and is specifically fixed at the edge of the main body.

[0039] Specifically, multiple limiting support plates 33 are provided along the length of the sub-shell 31. Each limiting support plate 33 has an integrally formed arc-shaped deformation area 34 on the side facing the sub-cover 32, and the edge of the deformation area 34 is flush with the edge of the sub-shell 31. After the sub-shell 31 and the cover are closed, the edge of the deformation area 34 abuts against the inner wall of the sub-cover 32, thereby supporting the sub-cover 32 and increasing the integrity of the accessory 12. Moreover, the diameter of the magnetic column 47 is the same as the width inside the sub-shell 31 and is set on one side of one of the limiting support plates 33. With the support of the limiting support plate 33, the magnetic column 47 is fixed more stably. Furthermore, the arc-shaped structure of the deformation area 34 increases the contact range with the magnetic column 47, further improving the stability of the magnetic column 47 and the sub-shell 31.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0041] The above are merely preferred embodiments of this application and are not intended to limit this application.
