Abstract
Description
Technical Field
[0001] This utility model relates to the field of seal management, and in particular to seal monitoring and management equipment. Background Technology
[0002] In business operations, the use of physical seals is extremely frequent and irreplaceable. In practice, the management of physical seals primarily relies on people, with employees reviewing materials and deciding on seal usage. However, when there are many materials, it's difficult for the staff in charge of seals to review every word of all materials to be stamped, nor can they constantly monitor the stamping process. Furthermore, staff in charge of seals may misuse seals or condone others' misuse. Therefore, incidents such as unauthorized stamping, unauthorized stamping, and stamping without approval frequently occur. Because it's impossible to prove that the stamping was unauthorized afterward, the legal consequences of the stamping are borne solely by the seal holder, causing irreparable losses. Therefore, a seal monitoring and management device that provides comprehensive monitoring, real-time recording, verifiable evidence, and does not affect the efficiency of seal usage is crucial for the operational security of seal holders.
[0003] Existing seal monitoring and management equipment is either limited in function, such as simply locking the seal in a cabinet and connecting it to an approval management system, authorizing relevant personnel to unlock it to prevent unauthorized use, but this still cannot solve the problem of monitoring the content of the seal. Unauthorized materials may be used without detection and subsequent proof is difficult to prove. Others have dedicated stamping areas with surveillance cameras installed above them to monitor stamping activities. However, in reality, these non-dedicated monitoring devices cannot clearly record the content of the materials being stamped, and the user can easily leave the monitoring range to use the seal without timely detection. Still others place the seal in a cylindrical container, which can only be opened with approval, and the use of the seal is simultaneously photographed or videotaped to record the content of the materials being stamped. However, this type of equipment is expensive, each cylinder can only hold one stamp, and the internal mechanism is complex and often jams. In addition, the camera shakes with the stamping action, so it needs to be stamped slowly to get a clear picture, resulting in low stamping efficiency. Furthermore, due to size limitations, the internal data storage space is limited, requiring uploading to the cloud for storage. It cannot meet the actual needs of enterprises and other businesses that have many stamps, large quantities, high stamping efficiency requirements, and high confidentiality of stamped content. Utility Model Content
[0004] Based on this, the purpose of this utility model is to overcome the defects or deficiencies of the existing technology and provide a stamp anti-tipping and anti-detachment device and stamp monitoring and management equipment that can monitor stamping in all directions and issue timely alarms for out-of-control states, effectively preventing users from stamping outside the monitoring range. It also has the advantages of data security, comprehensive evidence storage and low cost.
[0005] The anti-tipping and anti-detachment device for the seal includes a monitoring unit, which is installed on the seal and electrically connected to an alarm device. The monitoring unit detects the seal tipping over and detects the seal detaching from the anti-tipping and anti-detachment device and triggers the alarm device to issue an alarm.
[0006] Furthermore, the seal anti-tipping and anti-detachment device includes an RFID circuit board, an RFID read / write coil, an RFID sensing unit, a micro switch, a mercury switch, a housing, and wires; the micro switch, mercury switch, RFID read / write coil, and RFID sensing unit are disposed in the housing to form a monitoring unit; the micro switch, mercury switch, and RFID read / write coil are connected in series with the wires to form a wire harness monitoring circuit.
[0007] The monitoring unit is electrically connected to the alarm device. When the wiring harness monitoring circuit is on, the alarm device does not sound an alarm; when the wiring harness monitoring circuit is off, the alarm device is triggered to sound an alarm.
[0008] Furthermore, the mercury switch includes at least three mercury ball switches connected in series. Each mercury ball switch includes a mercury ball, a conductor, and an insulating housing. The conductor is disposed on the inner bottom surface of the insulating housing, and the mercury ball is movably disposed inside the insulating housing and located above the conductor.
[0009] Furthermore, the mercury ball switches are arranged symmetrically around the longitudinal central axis and tilted at a certain angle.
[0010] Furthermore, the conductor includes an enameled wire and a metal sheathing tube that wraps the enameled wire; the conductor is divided into at least two segments, and each pair of conductor segments is detachably connected by an anti-detachment connector.
[0011] Furthermore, a seal monitoring and management device is provided, including the aforementioned seal anti-tipping and anti-detachment device.
[0012] Furthermore, it also includes an alarm device and a stamp storage and retrieval device; the stamp storage and retrieval device includes a cabinet and several stamp storage containers, the cabinet has a space for storing the stamp storage containers, the stamp storage containers have a space for accommodating stamps and a stamp retrieval opening; the stamp storage containers can move between a use position and a storage position, when the stamp storage containers move to the storage position, the stamp retrieval opening closes; when the stamp storage containers move to the use position, the stamp retrieval opening is exposed.
[0013] Furthermore, the stamp storage container is a stamp storage tube or a stamp storage slot.
[0014] Furthermore, it also includes a transparent baffle and a surveillance camera. The transparent baffle is positioned above the cabinet to form a defined stamping area; the surveillance camera is positioned above the defined stamping area.
[0015] Furthermore, it also includes a UPS power-off protection device, which provides power to the seal anti-tipping and anti-detachment device, the seal storage and retrieval device, the alarm device, and the monitoring camera.

[0027] Existing seal monitoring and management equipment still suffers from blind spots. Analysis by the technical personnel of this application revealed that although monitoring cameras clearly record documents placed flat on the stamping work area, making it difficult for users to evade monitoring, some users, to avoid having the content of the stamped document recorded by the monitoring camera in front of the stamping work area, may stand the document upright, making the paper perpendicular to the plane of the stamping work area; or they may directly invert the paper to avoid monitoring, thus creating blind spots that the monitoring camera cannot detect. To address this, this application incorporates a seal anti-tipping and anti-detachment device 20 to monitor abnormal events such as disconnection, tipping, and detachment, and can remotely receive alarms or deactivate alarms. The following detailed description of this utility model, in conjunction with the accompanying drawings and embodiments, further illustrates this invention.
[0028] Example 1
[0029] Please see Figure 1 The diagram shows the structure of the cylindrical seal monitoring and management device of this application. The seal monitoring and management device includes: a seal storage and retrieval device 10, a seal anti-tipping and anti-detachment device 20, a camera and monitoring device, a remote authorization management device, an alarm device (not shown), and a UPS anti-power-off device 60.
[0030] In this embodiment, the stamp storage and retrieval device 10 is a cylindrical stamp storage and retrieval device, including a cabinet 12, several stamp storage cylinders 14a, several cylindrical push rods 16a, a selection knob 18, and an unlocking module 19. The cabinet 12 has a space for storing the stamp storage cylinders 14a and a lockable cabinet door 121; the top of the cabinet 12 has several openings matching the shape of the stamp storage cylinders 14a; the stamp storage cylinders 14a have a space for storing stamps 1 and a retrieval opening, with each stamp placed in one stamp storage cylinder. The cylindrical push rods 16a are fixed below the stamp storage cylinders 14a and can move vertically, allowing the stamp storage cylinders 14a to move along the opening direction at the top of the cabinet 12 between the use position and the storage position. When the stamp storage cylinders move to the storage position, the retrieval opening closes; when the stamp storage cylinders move to the use position, the retrieval opening is exposed. The switching knob 18 is used to control different stamp storage cylinders 14a to achieve circuit control of a single stamp storage cylinder 14a. The unlocking module 19 stores, collects, and compares fingerprint or facial information, and is electrically connected to the lifting cylinder push rod 16a to achieve circuit control of the lifting cylinder push rod 16a. In this embodiment, the unlocking module 19 is a fingerprint unlocking module.
[0031] The specific working process of the above-mentioned cylindrical stamp storage and retrieval device 10 is as follows: The unlocking module performs fingerprint or facial recognition on the user. Based on the successful fingerprint or facial recognition, the control circuit of the cylindrical push rod 16a is activated. The user can select the desired stamp storage cylinder 14a via the selection knob 18, moving the cylinder 14a to the usage position. At this time, the stamp storage cylinder 14a protrudes from the top of the cabinet 12, and the retrieval opening is exposed outside the cabinet. The user can retrieve the stamp 1 from the retrieval opening. Subsequently, the stamp storage cylinder 14a moves to the storage position. At this time, the retrieval opening of the stamp storage cylinder 14a is located inside the cabinet 12. The upper surface of the cabinet 12 is flush with the upper surface of the stamp storage cylinder 14a, forming a defined stamping area 15 for temporarily placing documents and the stamp 1, and providing support for the stamping operation. After the stamp is used, the stamp storage tube 14a moves back to the using position. After the user puts the stamp back, the stamp storage tube 14a moves back to the storage position, and the stamp use is complete. Preferably, at any given time, only one stamp storage tube 14a is in the using position, while the other stamp storage tubes 14a are in the storage position. This ensures that the use of a single stamp can be authorized and managed, avoiding problems such as unclear responsibility and management chaos caused by the simultaneous use of multiple stamps.
[0032] In some embodiments, the storage and retrieval of the seal can also be achieved through a valve, forming a valve-type seal monitoring and management device. See also Figure 2 This is a structural schematic diagram of the valve-type seal monitoring and management device of this application. The valve-type seal monitoring and management device is basically the same as the lifting cylinder seal monitoring and management device, except that: the seal storage cylinder 14a is replaced by the seal storage slot 14b, and the lifting cylinder push rod 16a is replaced by the valve push rod (not shown in the figure); the seal storage slot 14b is embedded in the top of the cabinet 12, and a seal retrieval port and a corresponding valve are provided on the top of the cabinet 12; the valve push rod is connected to the valve and pushes the valve to move between the use position and the storage position.
[0033] The specific working process of the valve-type stamp storage and retrieval device 10 is basically the same as that of the lifting cylinder-type stamp storage and retrieval device 10, except that: when the stamp storage slot 14b moves to the use position, the valve push rod opens the valve of the stamp storage slot 14b, allowing the user to retrieve the stamp 1 from the retrieval port at the top of the cabinet 12. When the stamp storage slot 14b moves to the storage position, the valve of the stamp storage slot 14b closes, making the valve flush with the upper surface of the cabinet 12, forming a defined stamping area 15. Furthermore, the stamp storage and retrieval device 10 is electrically connected to a remote authorization management device, enabling the user to retrieve the stamp after authorization by the remote authorization management device, and also enabling safekeeping when not in use; the stamp storage and retrieval device 10 is connected to the alarm device, thus improving the security of safekeeping.
[0034] Please see Figure 3 This is a schematic diagram of the anti-tipping and anti-detachment device for seals in this application. The anti-tipping and anti-detachment device 20 for seals includes an RFID sensor 22, a micro switch 24, a mercury switch 25, a housing 26, and a wire 28.
[0035] Specifically, the RFID sensor 22 includes an RFID circuit board 221, an RFID read / write coil 222, and an RFID sensing unit 223. The RFID circuit board 221 is disposed within the stamp storage and retrieval device 10, preferably within the cabinet 12, and is electrically connected to the RFID read / write coil 222. The RFID sensing unit 223 includes an RFID sensing chip and an RFID sensing coil. The RFID sensing unit 223 is stacked close to the RFID read / write coil 222, and after read / write registration, becomes a chip identifiable by the RFID read / write coil 222. The micro switch 24 is disposed on the inner wall of the housing 26, with its actuating piece protruding from the housing 26 and connected to the stamp 1. The micro switch 24, mercury switch 25, RFID read / write coil 222, and RFID sensing unit 223 are disposed within the housing 26, forming a monitoring unit A; wherein the micro switch 24, mercury switch 25, and RFID read / write coil 222 are connected in series with the wire 28 to form a wire harness monitoring circuit. The wire 28 extends from the housing 26 and its end is fixed inside the seal storage and retrieval device 10 to limit the usage range of the seal 1, allowing the user to use the seal 1 within the monitoring range of the recording and monitoring device. When the wiring harness monitoring circuit is on, the alarm device does not sound; when the wiring harness monitoring circuit is off, the alarm device is triggered to sound an alarm.
[0036] The RFID sensor 22 enhances the security of the seal. Specifically, if someone cuts the wire 28 and short-circuits it, making the wire segment circuit conductive, the alarm device may not be triggered. The RFID sensor 22 can be configured with a secure registration ID, which cannot be simulated using analog signals. After the wire segment is short-circuited, the connection between the RFID circuit board 221 and the RFID read / write coil 222 of the RFID sensor 22 is broken, preventing it from sensing the signal from the RFID sensing unit 223. Therefore, it outputs a low level, triggering the alarm device.
[0037] The mercury switch 25 is preferably composed of 3-5 mercury ball switches connected in series, arranged symmetrically around the longitudinal central axis and tilted at a certain angle. It should be noted that the watermark ball and conductor inside the mercury ball switch are in contact, forming a conductive circuit; in a non-contact state, the circuit is broken. A single mercury ball switch can only switch the watermark ball and conductor from a contact state to a non-contact state when the tilt angle is greater than 90 degrees. In this application, the spacing between each mercury ball switch and its tilt angle relative to the vertical central axis are equal and adjustable, ensuring that when the switch is tilted by the same angle in any direction, the watermark ball and conductor inside the mercury ball switch are in a non-contact state. When any mercury switch is disconnected, the read / write coil circuit is disconnected, thus overcoming the limitation of a single mercury ball switch on the sensing range of the stamp's tilt angle. Specifically, the conductor is disposed on the inner bottom surface of the insulating housing of the mercury ball switch, and the mercury ball is movably disposed inside the insulating housing and located above the conductor. When the bottom of stamp 1 is facing down, the bottom of monitoring unit A is also facing down, and the mercury ball is in contact with the conductor and turns on the wiring harness monitoring circuit. When stamp 1 tilts and its bottom is no longer facing down, the mercury ball rolls away from the conductor under the action of gravity, causing the wiring harness monitoring circuit to disconnect and the alarm device to sound an alarm.
[0038] As a further optimization of the above solution, the conductor 28 specifically includes an enameled wire (not shown in the figure) and a metal sheath 232 wrapping the enameled wire. Preferably, the conductor 28 is divided into two sections, and the two sections are detachably connected by an anti-detachment connector 233.
[0039] When the monitoring unit A is fixed on the seal, the RFID circuit board 221 will not detect the RFID sensor and will output a low level when the following events occur, triggering a local alarm and a remote alarm by connecting to the alarm device: (1) the sensor is removed or detached from the seal; (2) the conductive wire is cut in any way; (3) the seal is tilted at any angle beyond the trigger value.
[0040] The wiring harness monitoring circuit not only prevents the monitoring unit A from being removed, but also prevents the seal from being inverted or tilted, and prevents the wiring from being cut. More importantly, compared to directly connecting a conductive wire and switch into a single circuit system, this system uses RFID. This is primarily to address the possibility of someone short-circuiting or creating other simulated circuits at the cut end after the wiring is cut. The uniqueness of RFID registration and its non-re-registration outside the seal storage and retrieval device 10 ensure that the seal cannot be restored to a simulated uncut state after being cut. This ensures that the seal is confined within the monitoring range and can only be stamped vertically, ensuring that the stamped surface is under the monitoring camera's recording. Of course, the anti-detachment connector 233 also considers situations where the seal needs to be borrowed. Once approved or remotely set by headquarters, the alarm will be deactivated in the cut state. In this case, the approver or headquarters can also know the duration of the seal being borrowed and whether it has been returned on time through status changes. Of course, the system also takes into account the vulnerability of monitoring unit A due to frequent use. Therefore, a metal cable conduit 232 is used to protect the cable. At the same time, a round hole is provided at the protrusion to connect the hanging objects on the cable. When the stamp is returned to its place, the cable conduit will be automatically pushed back into the box, making it easier to store and reducing bending (in some embodiments, the cable conduit can also be replaced with a self-winding wire). Even if it is damaged, a new cable harness monitoring unit can be replaced by opening the box and re-registered for use.
[0041] The advantage of monitoring unit A is its stable connection, preventing false alarms caused by unstable sensing. However, its disadvantages include certain limitations in use and potential wear and tear on the wiring harness over time. Therefore, in some embodiments, wireless sensing can replace the wiring harness in the monitoring unit. Specifically, the area of the RFID read / write coil 222 is increased, and its position is adjusted to the outer top surface of the cabinet 12. A non-metallic panel is placed over the RFID read / write coil 222 to serve as an ink pad. The RFID read / write coil 222 senses whether the stamp has moved out of the designated range by sensing the RFID sensing unit 223 within the housing 26. In this embodiment, the micro switch 24 and mercury switch 25 are connected in series with the RFID sensing unit 223 within the housing 26, rather than with the RFID read / write coil 222. This achieves the same function as wiring harness monitoring.
[0042] The recording and monitoring device includes a transparent baffle 32, a recording host 33, and a first monitoring camera 34. The transparent baffle 32 is positioned above the cabinet, forming a semi-enclosed space to limit the use of the seal 1 within this semi-enclosed space, creating a defined stamping area 15 above the cabinet 12. The first monitoring camera 34 is positioned 0.5 to 0.8 meters above the defined stamping area 15, with a monitoring range exceeding the area of the defined stamping area 15, and provides high-definition recording to capture the specific content of the stamped document. Preferably, a second monitoring camera is also included, positioned 1.2 to 1.5 meters above the defined stamping area 15, with a monitoring range extending 0.5 to 1 meter beyond the overall seal monitoring and management equipment, and provides low-definition recording to capture the appearance, clothing, facial features, and behavior of anyone approaching the equipment. The videos recorded by the first monitoring camera 34 and the second monitoring camera are stored on the hard drive within the recording host 33, which is built into the cabinet and accessible only to investigators. Two surveillance cameras working together can clearly record evidence of the person using the seal, the person taking the seal, the vandal, and the content of the seal, and have a strong deterrent effect. It should be noted that the number of surveillance cameras is not a limitation on the scope of this invention.
[0043] The remote authorization management device includes a fingerprint module and an IoT remote switch 42. The highest-authorized user can manage the registration and deletion of fingerprint-authorized users through the IoT remote switch. This allows for the timely removal of authorization from departing seal management personnel and remote approval of fingerprint permission switching to accommodate special circumstances such as leave or business trips for seal management personnel. Furthermore, it prevents local seal management personnel from arbitrarily transferring seal access rights, ensuring that only one person has access rights at any given time, thus preventing issues related to overlapping permissions and difficulty in attributing responsibility.
[0044] The alarm device is used to issue alarm prompts at both the local and remote control ends. It includes an IoT remote transmitter 52, an audible and visual alarm, and several vibration switches. In conjunction with the aforementioned anti-tipping and anti-detachment device for the seal, it can promptly issue local alarms when events such as abnormal handling or use of the seal, unauthorized removal from the monitoring range, or forced damage to the seal storage and handling device 10 occur. Simultaneously, it remotely sends information to headquarters, enabling timely detection and effectively preventing the problem of unnoticed abnormalities after the seal has been returned to its proper place. Specifically, the alarm device can be an audible and visual alarm, capable of quickly and promptly alerting employees to abnormal seal usage.
[0045] The UPS power outage protection device 60 includes a 48V / 24V / 12V DC battery and a charging and discharging system, providing power to the seal anti-tipping and anti-detachment device, the seal storage and retrieval device, the alarm device, and the monitoring camera. Under normal operating conditions, the device is powered by 220V AC mains. In the event of an unexpected power outage or manual disconnection of the mains power, the UPS power outage protection device automatically activates, continuously supplying power to the various devices within the equipment. This device effectively prevents the monitoring and alarm devices from malfunctioning due to accidental or manual power cut-off after the seal has been removed.
[0046] Compared to existing technologies, this application ensures the following control over seals: 1. During normal use, the user's physical characteristics and all materials used for sealing are clearly recorded and can be stored for a relatively long time; 2. Unauthorized departure from the monitored area will be promptly recorded and trigger an alarm; 3. When using the seal in the monitored area, if it is inverted or tilted, it will be promptly recorded and trigger an alarm to avoid being recorded by cameras; 4. After approval, the user can leave the monitored area; 5. The duration of departure and the time of return to the cabinet can be recorded; 6. Headquarters can revoke or change the user's access rights at any time; 7. Remote access control and alarms do not rely on WLAN, but on a more stable, economical, and local network-independent IoT system. Specifically, this application can monitor irregular seal usage that may occur in blind spots and issue timely alarms, effectively preventing users from stamping unapproved documents in blind spots at a lower cost. In addition, for irregular user behavior, the seal anti-tipping and anti-detachment device can promptly trigger the alarm device, reducing the inconvenience and delay caused by searching for monitoring footage. Furthermore, the limit line restricts the movement range of the stamp within the stamping work area, ensuring that the stamp is used within this area. It can also promptly detect the removal of the anti-tipping and anti-detachment device, triggering an alarm in a timely manner. An alarm can also be triggered if the limit line is cut. Furthermore, by adjusting the tilting angle of the inner shell of the anti-tipping and anti-detachment device, the range of detectable tilting angles is expanded, improving monitoring sensitivity. Furthermore, the anti-tipping and anti-detachment device, in conjunction with a monitoring camera, forms a comprehensive monitoring system without blind spots. The stamp monitoring and management equipment of this application, through the combination of a stamp storage and retrieval device 10, a stamp anti-tipping and anti-detachment device 20, a recording and monitoring device, a remote authorization management device, an alarm device (not shown in the figure), and a UPS power outage protection device 60, achieves efficient, low-cost, and highly secure stamp management.
[0047] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and this utility model also intends to include these modifications and variations.
