Description

Technical Field

[0001] The present invention belongs to the technical field of seal authorization management, and particularly relates to an intelligent seal control method and system based on image monitoring. Background Art

[0002] A limit device and an identity recognizer are provided in the intelligent seal. The identity recognizer verifies the identity of the user and controls the limit device to release the restriction on the seal, enabling the seal to complete the stamping action. Thus, authorization management of the seal is achieved.

[0003] As described in the Chinese utility model patent "Electronic Fence Seal System" (Application No.: 201921253445.5, Authorization Publication Date: January 7, 2020), it includes a fence device and an intelligent seal; the fence device includes an identification terminal, a workbench, a reader-writer, and a camera; a limit device capable of restricting the stamping action and a controller capable of controlling the limit device are provided in the intelligent seal, and a digital tag is installed on the intelligent seal; the identification terminal and the controller are connected by wireless communication.

[0004] Its working process is: the antenna of the reader-writer on the workbench forms an identification range for the digital tag, and the camera on the workbench forms an image acquisition range, making the overlapping area of the identification range and the image acquisition range serve as the electronic fence. After the digital tag and image of the intelligent seal within the electronic fence range are recognized, the locking of the limit device can be released to perform the stamping action, restricting the working range where the intelligent seal can perform stamping, and preventing the intelligent seal from performing the stamping action when it is outside the electronic fence.

[0005] The problems existing in the above seal management system are as follows:

[0006] 1. Complex structure: This system relies on an electronic fence composed of an identification terminal, a workbench, a reader-writer, a camera, etc. to restrict the working range of seal stamping, enabling stamping only within the electronic fence range. Although the range is restricted, it brings limitations to the flexibility of the stamping position. Especially, since the workbench of this system has a certain volume and a reader-writer, a camera, and a support with a certain height need to be placed on it, there are significant limitations to the scenarios where this system is used; the number of devices required is relatively large, the structure is rather cumbersome, and the cost is relatively high.

[0007] 2. Difficult to carry out: It is a common situation in enterprise operations to take the seal out for stamping. The workbench of the above seal management system has a large volume and is not convenient to carry out, so it is difficult for this system to solve the problem of photographing and controlling the seal during off-site work. Summary of the Invention

[0008] The object of the present invention is to provide an intelligent seal control method based on image monitoring, which has high security and good traceability.

[0009] Another object of the present invention is to provide an intelligent seal control system based on image monitoring.

[0010] The technical solution for achieving the object of the present invention is as follows:

[0011] An intelligent seal control method based on image monitoring, wherein the intelligent seal displays an identity image through an indicating device, the identity image features match the intelligent seal, and when using the intelligent seal, the indicating device of the intelligent seal is under image monitoring. When the identity image features displayed by the indicating device do not match the corresponding monitored image features, the intelligent seal is in a locked state.

[0012] The technical solution for achieving another object of the present invention is as follows:

[0013] An intelligent seal control system based on image monitoring, comprising an intelligent seal 2 and a camera terminal 1. The intelligent seal 2 includes a stamping limit device 21 signal-connected to a controller 22; the intelligent seal 2 further includes an indicating device 23 signal-connected to the controller 22; the controller 22 controls the indicating device 23 to display an identity image, and the identity image features match the intelligent seal 2; the camera terminal 1 faces the indicating device 23 and is signal-connected to the controller 22 in a wired or wireless manner, and can continuously collect the identity image displayed by the indicating device 23 to obtain a monitored image; when the identity image features displayed by the indicating device 23 do not match the corresponding monitored image features, the intelligent seal is in a locked state.

[0014] Compared with the prior art, the present invention has the following remarkable advantages:

[0015] 1. High security and good traceability: The present invention continuously collects the image of the indicating device of the intelligent seal through the camera terminal. When the image features of the indicating device recognized by the camera terminal match the image features displayed by the indicating device, the controller controls the stamping limit device to be in an unlocked state, and at this time, stamping can be performed, and part or all of the images of the intelligent seal and the stamped document are photographed and recorded; realizing forced photographing and evidence retention for stamping, the stamping action is monitored by the camera terminal before and after, and the image will be photographed and saved when stamping, which is conducive to on-site monitoring and post-event traceability; when the image features of the indicating device recognized by the camera terminal do not match the image features displayed by the indicating device, the controller controls the stamping limit device to be in a locked state, and at this time, stamping cannot be performed; not only has high security, but also has good traceability; especially when the indicating device is a changing image, the collected image is not easy to be faked, improving security.

[0016] 2. Simple structure and wide application: The system of the present invention consists of a camera terminal and an intelligent seal, with a simple composition. It is not limited to specific places, and the placement position of the entire system is flexible during use, with low requirements for the space used. In particular, the camera terminal can be a mobile phone with a camera that is widely used, so there is no need to add a special device for photography to increase the user cost, and it can well solve the need for photo control when the seal is taken out for stamping.

[0017] The following further describes the present invention in detail with reference to the accompanying drawings and specific embodiments. Description of the Drawings

[0018] Figure 1 is the main flowchart of the intelligent seal control method based on image monitoring of the present invention.

[0019] Figure 2 is the structural block diagram of the intelligent seal control system based on image monitoring of the present invention.

[0020] In the figure, camera terminal 1, intelligent seal 2, stamping limit device 21, controller 22, indicating device 23. Specific Embodiments

[0021] For the intelligent seal control method based on image monitoring of the present invention, the intelligent seal displays an identity image through an indicating device, and the identity image features match the intelligent seal. When using the intelligent seal, the indicating device of the intelligent seal is under image monitoring. When the identity image features displayed by the indicating device do not match the corresponding monitored image features, the intelligent seal is in a locked state.

[0022] To use the intelligent seal, the present invention places the identity image matching the identity of the intelligent seal and the intelligent seal body under image monitoring together, obtains a monitored image by continuously collecting the identity image, and compares the monitored image features with the identity image features. The results may be: 1. The features do not match, and the intelligent seal is in a locked state and cannot be stamped; 2. Matching in the early stage, the intelligent seal is unlocked, and not matching in the later stage, that is, when intending to stamp, the indicating device of the intelligent seal is out of image monitoring, and the intelligent seal returns to the locked state and still cannot be stamped; 3. Always matching, the intelligent seal remains in the unlocked state and can be used for stamping. Thus, the effective control of the intelligent seal is achieved in a relatively simple manner.

[0023] Preferably, when the identity image features displayed by the indicating device match the corresponding monitored image features, the intelligent seal is unlocked and can be stamped.

[0024] As an improvement,

[0025] When the identity image features displayed by the indicating device match the corresponding monitoring image features, save the monitoring image, which also includes partial or all images of the intelligent seal and the stamped document.

[0026] As a further improvement, when the intelligent seal is in the unlocked state and stamping, save the monitoring image, which also includes partial or all images of the intelligent seal and the stamped document.

[0027] When the identity image features displayed by the indicating device match the corresponding monitoring image features, the intelligent seal remains in the unlocked state continuously, save partial or all images including the intelligent seal and the stamped document, realize forced photographing and evidence retention for stamping, the stamping action is monitored by the camera terminal before and after, and the image will be photographed and saved when stamping, which is conducive to current monitoring and retrospective investigation afterwards.

[0028] As an embodiment, the identity image is an infrared waveform image matching the intelligent seal.

[0029] At this time, the image features can be the frequency value of the infrared lamp flashing according to a certain waveform or the ratio of the on-off time interval flashing according to a certain waveform, etc. As another embodiment, the identity image is a two-dimensional code or a bar code matching the intelligent seal.

[0030] At this time, the image features can be a set of numbers, some text information, etc. corresponding to the two-dimensional code or the bar code.

[0031] Preferably, the monitoring image is collected by a camera terminal facing the intelligent seal.

[0032] More preferably, the camera terminal is a mobile camera terminal.

[0033] Using a mobile camera terminal makes the use of the intelligent seal more flexible and convenient.

[0034] Most preferably, the mobile camera terminal is a smart phone.

[0035] With the popularization of smart phones, using a smart phone as the camera terminal to collect the monitoring image not only ensures the safe control of the intelligent seal, but also is convenient to use, and does not require additional hardware devices, simplifies the system, and reduces the cost.

[0036] As Figure 1 shown, as a preferred implementation manner, the intelligent seal control method based on image monitoring of the present invention includes the following steps:

[0037] (10) Display the identity image: The intelligent seal displays the identity image through the indicating device, and the identity image features match the intelligent seal;

[0038] (20) Monitoring image acquisition: When the intelligent seal is to be used, continuously collect the above-mentioned identity images to obtain monitoring images;

[0039] (30) Seal control: Compare the monitoring image with the identity image. When the features of the monitoring image match the features of the identity image, unlock the intelligent seal; when the features of the monitoring image do not match the features of the identity image, lock the intelligent seal.

[0040] (40) Image saving: When the features of the identity image displayed by the indicating device match the features of its corresponding monitoring image or when stamping, save the monitoring image.

[0041] As Figure 2 shown, the intelligent seal control system based on image monitoring of the present invention includes an intelligent seal 2 and a camera terminal 1. The intelligent seal 2 includes a stamping limiting device 21 signal-connected to a controller 22; the intelligent seal 2 further includes an indicating device 23 signal-connected to the controller 22;

[0042] The controller 22 controls the indicating device 23 to display an identity image, and the features of the identity image match the intelligent seal 2;

[0043] The camera terminal 1 faces the indicating device 23 and is signal-connected to the controller 22 by wire or wirelessly, and can continuously collect the identity image displayed by the indicating device 23 to obtain a monitoring image;

[0044] When the features of the identity image displayed by the indicating device 23 do not match the features of its corresponding monitoring image, the intelligent seal is in a locked state.

[0045] Correspondingly, the indicating device 23 of the intelligent seal 2 is under image monitoring. When the features of the identity image displayed by the indicating device 23 match the features of its corresponding monitoring image, the intelligent seal 2 is unlocked and can be stamped.

[0046] When the features of the identity image displayed by the indicating device 23 match the features of its corresponding monitoring image, save the monitoring image, and the monitoring image also includes part or all of the images of the intelligent seal 2 and the stamped document.

[0047] When the intelligent seal 2 is in an unlocked state and stamping, save the monitoring image, and the monitoring image also includes part or all of the images of the intelligent seal 2 and the stamped document.

[0048] To use the intelligent seal, the present invention places the identity image matching the identity of the intelligent seal and the intelligent seal body under image monitoring together. Monitoring images are obtained by continuously collecting the identity images, and the features of the monitoring images are compared with the features of the identity images. The possible results are as follows: 1. The features do not match, and the intelligent seal is in a locked state and cannot be stamped; 2. The match is successful in the early stage, and the intelligent seal is unlocked. If the match fails in the later stage, that is, when intending to stamp, the indicating device of the intelligent seal is out of the image monitoring, and the intelligent seal returns to the locked state and still cannot be stamped; 3. The match is always successful, and the intelligent seal remains in the unlocked state and can be used for stamping. Thus, the effective control of the intelligent seal is achieved in a relatively simple manner.

[0049] Preferably, the indicating device 23 is located at the lower part of the intelligent seal 2, close to the document to be stamped, so that when the imaging terminal 1 clearly captures the image of the indicating device 23, the imaging terminal 1 can simultaneously clearly capture part or all of the content of the stamped document.

[0050] The imaging terminal is a mobile imaging terminal.

[0051] Preferably, the mobile imaging terminal is a smart phone.

[0052] Using a smart phone as the imaging terminal to collect the monitoring images not only ensures the safe control of the intelligent seal, but also is convenient to use, and does not require additional hardware devices, simplifies the system, and reduces the cost.

[0053] The feature comparison between the monitoring image and the identity image can be realized either in the smart phone or in the controller 22. With the increasingly powerful functions of smart phones, it is preferably realized in the smart phone, thereby simplifying the functions of the controller 22 and saving costs.

[0054] Identifying the feature values of the monitoring images is a conventional technology and will not be described in detail here.

[0055] The indicating device 23 is at least one indicator light or display screen.

[0056] As a preferred solution, the indicator light is an infrared light.

[0057] As a further preference of the above preferred solution,

[0058] The infrared light flashes according to a certain waveform.

[0059] The infrared light flashing according to a certain waveform not only facilitates using the waveform to uniquely match the identity image with the intelligent seal 2 and increases the security, but also facilitates the imaging terminal to clearly capture the identity image.

[0060] When the indicating device 23 is a display screen, as a preferred solution, the content displayed on the display screen includes a two-dimensional code or a bar code.

[0061] By using a display screen as the indicating device 23, more complex images such as two-dimensional codes or barcodes, or other graphics that are both easy to identify and unique can be displayed, so that the image representing the identity of the intelligent seal 2 is more recognizable and the security is increased.
