Description

Technical Field

[0001] The present invention relates to the field of seal technology, and in particular to a manual-automatic combined cloud intelligent seal device and a method of using the same. Background Art

[0002] In recent years, a new type of IoT product—the cloud-based intelligent seal terminal—has been introduced and widely adopted. Equipped with a high-performance CPU, multiple (three or more) cameras, a 4G module, a security module, a fingerprint sensor, a location sensor, and other components, it can monitor the use of built-in physical seals. By coordinating with the intelligent seal management platform (cloud platform server + management terminal (PC or mobile), it can implement seal application and approval, pre-print document comparison, authorized unlocking, seal evidence snapshots, automatic generation of seal usage records (user, time, location, number of times, etc.), intelligent seal usage auditing, real-time seal usage monitoring and recording, and encrypted key upload to the management platform for storage and decryption review.

[0003] This cloud-based smart seal, based on the Internet of Things (IoT), has revolutionized the traditional human-controlled seal management model, providing a highly secure, networked, digital, and intelligent management solution for the entire seal usage process. Due to its high security, high efficiency, and high intelligence, it has been widely welcomed by the market. However, due to its important position and role in the market, as well as its widespread use, it also exposes potential risks in seal usage control during use, which may cause certain economic losses to users. The main potential risks are as follows:

[0004] Potential risks: When a user is authorized to use a seal, since the seal is still used by manually pressing the seal handle, a situation that may easily occur is: after pressing the smart seal handle to reach the paper to be stamped and completing the stamping, if the seal handle is not released and the smart seal is quickly moved to another paper to be stamped or rubbed, more than two stamps may be produced within the time window of one seal pressing. Since it is difficult to accurately predict the dwelling time of the smart seal on the paper to be stamped after authorization, there is a subjective factor of manual control, which leads to the risk of stealing the seal or rubbing. Although the smart seal can also set a certain time limit for this situation and alarm when it times out, due to the limitation of its lower limit time (limited by various detection and processing time limits), there is still a risk of being secretly stamped more than twice. Therefore, it still brings certain risks to users.

[0005] In order to avoid the potential situation of multiple stamp marks being produced within the time window of a single seal press, this patent provides a technical solution that can control this potential risk: a manual-automatic combined cloud intelligent seal device and its use method. Summary of the Invention

[0006] The purpose of the present invention is to provide a manual-automatic combined cloud intelligent seal device and a method of using the same, which solves the problem of malicious behavior that may exist when manually stamping with a cloud intelligent seal, that is, the adverse consequence of producing more than two stamp marks with one manual press.

[0007] To achieve the above object, the present invention provides the following solutions:

[0008] A manual-automatic combined cloud intelligent seal device includes a control system and a seal motion control assembly. The seal motion control assembly includes a drive mechanism, a seal handle, a seal outer sleeve, a seal inner sleeve arranged in the seal outer sleeve, a seal clamp, a conversion device, and a compression spring sleeved on the outer wall of the seal inner sleeve. The lower end of the compression spring is fixed to the central partition of the seal outer sleeve, and the upper end of the compression spring is fixed to the upper end of the seal inner sleeve through the compression spring upper gear. The seal handle passes through a sliding groove opened on both sides of the seal outer sleeve and is connected to the two fixed ears of the compression spring upper gear. The control system is used to control the seal stamping.

[0009] Preferably, a motor fixing device is provided in the inner sleeve of the seal, and the motor fixing device includes a motor fixing plate, and a through hole for the output shaft of the motor to pass through is opened on the motor fixing plate.

[0010] Preferably, the driving mechanism includes a motor and a conversion device provided at an output end of the motor, the conversion device is connected to the physical seal fixture, and the motor is used to drive the movement of the physical seal fixture.

[0011] Preferably, the conversion device includes a mounting sleeve for connecting to the output end of the motor and two sets of impellers arranged at different heights, vertically arranged, and with opposite arc surfaces on the circumference of the mounting sleeve. The two sets of impellers are used to hang or drop hooks for the physical seal fixture.

[0012] A method for using a manual-automatic combined cloud intelligent seal device comprises the following steps:

[0013] After unlocking the seal lock with the authorization code, press down the seal handle of the cloud smart seal by hand. The seal handle compresses the compression spring and drives the seal motion control assembly to move toward the paper surface to complete the manual part H1 stamping stroke;

[0014] After the manual downward stroke H1 is completed, the control system determines whether the stamping conditions are met. If so, it executes the automatic safety stroke H2 part of the action to complete the stamping. After the stamping is completed, the H2 stroke is retracted upward to the initial position; if not, release the manual pressing seal handle, and the physical seal automatically returns to the initial position under the action of the compression spring, and the H1 return stroke is completed after the stamping is completed.

[0015] Preferably, the method for obtaining the seal authorization code is as follows:

[0016] After the seal application document is approved, its management and control platform will issue a seal permission code to the user's APP or PC client software. The method for this manual and automatic cloud smart seal to obtain the seal authorization code is to collect the seal user's face or fingerprint through the set upper video or fingerprint collection device. On the one hand, it is encrypted for local storage, and on the other hand, it is uploaded to the server for comparison with the registered data. After the two are consistent, the seal authorization code is issued to the seal user, allowing the seal user to use the seal. At the same time, the electronic certificate of the seal user's collected data is encrypted and timestamped, and uploaded to the server.

[0017] Preferably, the conditions for compliance are no fraudulent visual behavior or the OCR comparison of the printed document and the application document is consistent, and the no fraudulent visual behavior includes no collection camera blocking behavior, or no blank paper insertion behavior, or no other paper insertion behavior.

[0018] Preferably, the non-compliance condition is that there is fraudulent visual behavior or the OCR comparison between the printed document and the application document is inconsistent, and the fraudulent visual behavior includes blocking the acquisition camera, inserting blank paper, or other paper insertion behavior.

[0019] Preferably, the automatic safety stroke H2 operates as follows: forward rotation data is output to the DC motor to drive the motor forward. During forward rotation, the conversion device converts the rotational motion into vertical motion, driving the physical seal fixture to push downward within the inner sleeve of the seal. The physical seal fixture drives the physical seal to place an imprint on the document to be stamped, completing the automatic safety stroke H2 forward stroke. After stamping is completed, reverse rotation data is output to the DC motor, driving the physical seal to return to its initial position, completing the automatic safety stroke H2 reverse stroke.

[0020] Preferably, it can be evolved into the following three usage modes: 1. N imprints are generated by N*(1 H1 stroke + 1*H2 automatic safety stroke); 2. N imprints are generated by 1*H1 stroke + N*H2 automatic safety stroke; 3. N imprints are generated by (N+X)*H1 stroke + X*H2 (1≤X≤M, M can be greater than N, X is the number of fraudulent behaviors) automatic safety stroke. Especially for usage mode 3, in the process of generating N imprints, the H2 stroke is first descended, and then the N*H1 stroke is performed. If one fraudulent situation is detected, an H2 return can be performed, and an H1 return is required. If X fraudulent behaviors occur during the generation of N imprints, X*H2 lifting and shrinking operations and (N+X)* pressing operations are required.

[0021] Compared with the prior art, the present invention has achieved the following technical effects:

[0022] 1. The present invention realizes the combination of manual and automatic stamping strokes, and can perform seal retraction protection action in an emergency; it solves the possible malicious behavior when manually stamping with the cloud smart seal, that is, the adverse consequence of producing more than two stamp marks with one manual press.

[0023] 2. The present invention adds an automatic safety stroke H2 during a stamping stroke, which can ensure safe stamping within a stamping time window, avoid the risk of multiple stamps being generated in one stamping action, and prevent the risk of the stamp being misappropriated or stolen.

[0024] 3. Before the automatic safety journey is started, the present invention can determine whether the automatic safety journey stamping can be performed based on the results of AI vision, OCR recognition, etc., that is, this solution has an intelligent pre-audit function before printing.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] The purpose of the present invention is to provide a manual-automatic combined cloud intelligent seal device and a method of using the same, which solves the problem of malicious behavior that may exist when manually stamping with a cloud intelligent seal, that is, the adverse consequence of producing more than two stamp marks with one manual press.

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] refer to Figures 1 to 2 The invention also provides a method for controlling the seal of a seal holder, a method for controlling the seal of a seal holder, and a method for controlling the seal of a seal holder.

[0038] refer to Figures 1 to 2 A motor fixing device is provided in the inner sleeve of the seal, and the motor fixing device includes a motor fixing plate, and a through hole is opened on the motor fixing plate for the output shaft of the motor to pass through.

[0039] refer to Figure 1 The driving mechanism includes a motor and a conversion device arranged at the output end of the motor, the conversion device is connected to the physical seal clamp, and the motor is used to drive the movement of the physical seal clamp.

[0040] refer to Figures 6 and 7The conversion device includes a mounting sleeve for connecting to the output end of the motor and two sets of impellers arranged at different heights, vertically arranged, and with opposite arc surfaces in the circumferential direction of the mounting sleeve. The surfaces of the two sets of impellers are arc surfaces, and the two sets of impellers are used to hang or push the hooks of the physical stamp clamp.

[0041] refer to Figure 2 The control system includes a CPU circuit board, a DC motor drive chip, a manual stroke detection switch and a power supply. The CPU circuit board is arranged in the circuit board slot opened in the seal jacket, and the DC motor drive chip is connected to the motor line.

[0042] Furthermore, it also includes a battery power supply and fast charging module, a security module, a 4G module, a video acquisition module, a display module and a storage module.

[0043] A method for using a manual-automatic combined cloud intelligent seal device comprises the following steps:

[0044] 1) Press the power button of the cloud smart seal terminal and wait for the cloud smart seal to start up;

[0045] 2) Obtain the seal authorization code (after the seal application document is approved, its management and control platform will issue a seal permission code to the user on the APP or PC client software). The method for this manual and automatic cloud smart seal to obtain the seal authorization code is to collect the seal user's face or fingerprint through the set-up upper video or fingerprint collection device. On the one hand, it is encrypted for local storage, and on the other hand, it is uploaded to the server for comparison with the registered data. If the two are consistent, the seal authorization code is issued to the seal user, allowing the seal user to use the seal. At the same time, the electronic certificate of the seal user's collected data is encrypted and timestamped, and uploaded to the server to ensure that the seal user is a "real person" for evidence collection.

[0046] 3) The user enters the obtained seal authorization code into the authorization interface of the cloud smart seal to open the smart lock of the cloud smart seal.

[0047] 4) After the user hears the voice prompt of the cloud smart seal unlocking successfully, he / she quickly places the smart seal on the paper to be stamped and presses down the seal handle of the cloud smart seal. The seal handle compresses the compression spring and drives the seal motion control assembly to move toward the paper surface to complete the manual downward part H1 stroke (see Figure 6 shown).

[0048] 5) After the manual downward stroke H1 is completed, continue to press the seal handle of the Cloud Smart Seal for approximately 2 to 4 seconds. During this time, the Cloud Smart Seal CPU motherboard program will read the position sensor detection data to determine whether the manual stroke H1 is complete. Once the manual stroke is completed (i.e., switch K1 is closed), the program's vision module and OCR recognition module will be immediately called to analyze and determine whether the seal application conditions are met.

[0049] If they match (i.e., there is no visual evidence of fraud, and the document to be stamped matches the application document after OCR comparison), the automatic safety process H2 part of the action is executed. That is, the DC motor forward rotation data is output to drive the DC motor forward. When the DC motor rotates forward, the conversion device converts the rotational motion into vertical motion, driving the physical seal fixture to push downward inside the seal inner sleeve. The physical seal fixture drives the physical seal to stamp the imprint on the document to be stamped, such as Figure 7 As shown, Figure 7 A schematic diagram of the operational structure of the Cloud Smart Seal's automatic security process, H2, is provided. Simultaneously, the Cloud Smart Seal's CPU motherboard program uses a seal document collection camera to capture seal document data, timestamps it, encrypts it, and uploads it to the server to ensure the authenticity of the seal document. After stamping, the motor is immediately started to reverse to its maximum reverse position, stopping the seal and ensuring security. Furthermore, the Cloud Smart Seal's CPU motherboard program uses a seal impression collection camera to capture seal impression data, timestamps it, encrypts it, and uploads it to the server to ensure the authenticity of the seal impression. After a stamp is completed, this Cloud Smart Seal achieves the "three-in-one" electronic certificate: "real person, real document, and real seal" verification, encryption, and upload to the cloud server. This "three-in-one" electronic certificate data uploaded to the cloud server can also be uploaded to a blockchain server for blockchain storage, ensuring that the "three-in-one" electronic certificate data cannot be tampered with.

[0050] If there is a mismatch (i.e., either visual fraud or an OCR discrepancy between the document used and the application), the application will be invalidated and the user will be instructed to release the manual seal handle. Once released, the seal handle, physical seal holder, and physical seal will automatically return to their initial positions due to the spring. (Note: Visual fraud includes but is not limited to malicious attempts to block the seal data collection camera, remove, insert, or transfer the seal paper, and other malicious attempts to use the seal.)

[0051] Furthermore, a method for using a manual-automatic combined cloud intelligent seal device can be derived from the following control methods and steps according to the actual use scenario of the seal:

[0052] 1) One-time seal application, N-print situation use control method embodiment 1

[0053] The seal usage method is: N seals are generated by N * H1 strokes + N * H2 automatic safety strokes. After unlocking with the seal authorization code, one seal requires one H1 stroke + one H2 stroke; N seals are formed by N * (one H1 + one H2).

[0054] 2) One-time seal application, N-seal scenario usage control method embodiment 2

[0055] The method for using the seal is as follows: N seals are generated by 1*H1 stroke + N*H2 automatic safety stroke. After unlocking with the seal authorization code, manually pressing the H1 stroke once, the corresponding N*H2 automatic safety strokes are performed at the N seal positions.

[0056] 3) One-time seal application, N-seal scenario use control method embodiment 3

[0057] The usage of this stamp is as follows: N stamps are generated by the automatic safety stroke of (N+X)*H1 + X*H2 (1≤X≤M, M can be greater than N, and X is the number of fraudulent attempts). Specifically for usage mode 3, during the N stamp generation process, the H2 stroke is first descended, followed by the N*H1 stroke. If a single fraudulent attempt is detected, an H2 retraction operation can be performed, and an H1 retraction operation is required. If X fraudulent attempts occur during the N stamp generation, X*H2 expansion and contraction operations are required, along with (N+X)*pressing operations.

[0058] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only intended to help understand the method and core concept of the present invention. At the same time, those skilled in the art will find that the specific implementation methods and application scopes may vary based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
