[0068] Example 1

[0069] Embodiment 1 of the present invention is a portable seal work box for physical seal management and control, which is also provided with a central control module (not shown in the figure) in the box body, which is respectively connected to the luminous printing plate 5, the image acquisition module and the locking component, and is used to determine the range of the area to be stamped according to the average actual distance between the stamp feature text and the horizontal edge and the vertical edge of the luminous printing plate 5, and to adjust the side length of the limited stamp area to the first corresponding side length of the limited stamp area according to the difference between the distance between the position of the feature text and the edge of the luminous printing plate 5 and the preset distance, and to adjust the luminous intensity of the luminous printing plate to the first corresponding luminous intensity value of the luminous printing plate according to the difference between the actual image clarity and the preset image clarity, and to adjust the luminous intensity of the luminous printing plate to the second corresponding luminous intensity value of the luminous printing plate according to the difference between the actual area ratio of the light-blocking area of ​​the document photo and the preset area ratio of the light-blocking area.

[0070] The seal working box of this embodiment sets the preset side length of the square area to be stamped, the preset distance, the preset image clarity, the preset blocked area ratio and the preset area ratio, determines the range of the area to be stamped according to the average actual distance between the stamped characteristic text and the horizontal edge and the vertical edge of the luminous printing plate 5, and adjusts the side length of the limited stamping area to the first corresponding side length of the limited stamping area according to the difference between the distance between the position of the characteristic text and the edge of the luminous printing plate 5 and the preset distance, thereby reducing the impact of unclear confirmation of the area to be stamped and unclear reflection of the area to be stamped by the characteristic text on the safety of the seal in the stamping process; by The difference between the clarity and the preset image clarity adjusts the luminous intensity of the luminous printing plate to the first corresponding luminous printing plate luminous intensity value, thereby reducing the impact on the security of seal usage due to the unclear identification of possible theft holes reflected by the difference in image clarity; by secondary adjusting the luminous intensity of the luminous printing plate to the second corresponding luminous printing plate luminous intensity value based on the difference between the actual area ratio of the light-blocking area of ​​the document photo and the preset area ratio of the light-blocking area, the impact of the unreasonable adjustment of the luminous intensity of the luminous printing plate 5 on the clarity of the camera photo and video recording, which leads to a reduction in the effectiveness of seal usage security supervision, thereby achieving an improvement in seal usage security.

[0071] Specifically, the central control module establishes a rectangular coordinate system based on the position of the stamped feature text recognized by the camera as the origin, and determines the range of the area to be stamped based on the average actual distance L between the stamped feature text and the horizontal edge and the vertical edge of the luminous printing plate 5. The central control module is provided with a preset side length L0 of the square area to be stamped.

[0072] If L≤L0, the central control module determines that L is the side length of the square area to be stamped;

[0073] If L>L0, the central control module determines that L0 is the side length of the square area to be stamped.

[0074] Furthermore, the working box described in this embodiment sets a preset side length of the square area to be stamped, and determines the scope of the area to be stamped based on the average actual distance between the characteristic stamped text and the horizontal and vertical edges of the luminous printing plate 5, thereby reducing the impact of the inaccurate determination of the scope of the area to be stamped on the effectiveness of seal supervision, and further achieving an improvement in the security of seal use.

[0075] Specifically, the central control module determines whether to adjust the side length of the limited printing area according to the distance C between the position of the characteristic text and the edge of the luminous printing plate 5. The central control module is provided with a preset first distance C1 and a preset second distance C2, wherein C1<C2.

[0076] If C≤C1, the central control module preliminarily determines that there is a risk of piracy, and uses the clarity of the image of the area to be stamped captured by the second camera 4 to perform a secondary determination on whether there is a risk of piracy;

[0077] If C1<C≤C2, the central control module determines that the distance between the position of the characteristic text and the edge of the luminous printing plate 5 is below the allowable range, calculates the difference △C between the distance between the position of the characteristic text and the edge of the luminous printing plate 5 and the preset distance, and adjusts the side length of the restricted printing area to the side length of the first corresponding restricted printing area, setting △C=C-C1;

[0078] If C>C2, the central control module determines that the distance between the position of the characteristic text and the edge of the luminous printing plate 5 is within the allowable range, and controls the camera to shoot and record the stamping process.

[0079] Furthermore, the working box described in this embodiment sets a preset first distance and a preset second distance, and determines whether to adjust the side length of the limited printing area based on the distance between the position of the characteristic text and the edge of the luminous printing plate 5, thereby reducing the impact of inaccurate judgment of the distance between the position of the characteristic text and the edge of the luminous printing plate 5 on the risk of piracy, and further achieving an improvement in the security of printing.

[0080] Specifically, the central control module adjusts the side length of the limited printing area to the first corresponding limited printing area side length La' according to the difference between the distance between the position of the characteristic text and the edge of the luminous printing plate 5 and the preset distance under the preset first distance condition, sets La'=La×γg, γg is the first adjustment coefficient of the side length of the limited printing area, and sets g=1, 2, wherein the central control module is provided with a preset first distance difference △C1, a preset second distance difference △C2, a preset first limited printing area side length adjustment coefficient γ1, a preset second limited printing area side length adjustment coefficient γ2, and a preset limited printing area side length La, wherein △C1<△C2, 1<γ1<γ2,

[0081] If △C≤△C1, the central control module determines not to adjust the side length of the limited printing area;

[0082] If △C1<△C≤△C2, the central control module determines to use γ1 to adjust the side length of the limited printing area;

[0083] If ΔC>ΔC2, the central control module determines to use γ2 to adjust the side length of the limited printing area;

[0084] The preset first distance condition is that the distance C between the position of the characteristic text and the edge of the luminescent printing plate 5 satisfies C1<C≤C2.

[0085] Furthermore, the working box of this embodiment sets a preset first distance difference, a preset second distance difference, a preset first limited printing area side length adjustment coefficient, a preset second limited printing area side length adjustment coefficient and a preset limited printing area side length. By adjusting the side length of the limited printing area to the first corresponding limited printing area side length according to the difference between the distance between the position of the characteristic text and the edge of the luminous printing plate 5 and the preset distance, the working box reduces the impact of inaccurate adjustment of the side length of the limited printing area on the safety of printing, and further achieves the improvement of the safety of printing.

[0086] Specifically, the central control module performs a secondary judgment on whether there is a risk of piracy based on the image clarity Q of the area to be stamped obtained by the second camera 4 under the preset second distance condition, wherein the central control module is provided with a preset first image clarity Q1 and a preset second image clarity Q2, wherein Q1<Q2,

[0087] If Q≤Q1, the central control module determines that there is no risk of piracy;

[0088] If Q1<Q≤Q2, the central control module determines that there is a first-level piracy risk, calculates the difference △Q between the image clarity of the area to be stamped and the preset image clarity, and adjusts the luminous intensity of the luminous printing plate to the corresponding value according to △Q, setting △Q=Q-Q1;

[0089] If Q>Q2, the central control module determines that there is a second-level piracy risk and issues a second-level piracy risk investigation notice;

[0090] The preset second distance condition is that the central control module completes the adjustment of the side length of the limited printing area and the distance C between the position of the characteristic text and the edge of the luminous printing plate 5 satisfies C≤C1.

[0091] Furthermore, the working box of this embodiment sets a preset first image clarity and a preset second image clarity, and makes a secondary judgment on whether there is a risk of piracy based on the image clarity of the area to be stamped obtained by the second camera 4. By taking into account the impact of the inaccurate judgment of the possible existence of theft holes reflected by the image clarity of the area to be stamped on the security of seal use, the security of seal use is further improved.

[0092] Specifically, the central control module adjusts the luminous intensity of the luminous printing plate to the first corresponding luminous printing plate luminous intensity value S' according to the difference between the actual image clarity and the preset image clarity under the preset image clarity condition, sets S'=S0×(1+αi) / 2, αi is the first luminous intensity adjustment coefficient, and sets i=1, 2, wherein the central control module is provided with a preset first image clarity difference △Q1, a preset second image clarity difference △Q2, a preset first luminous intensity adjustment coefficient α1, a preset second luminous intensity adjustment coefficient α2, and a preset luminous intensity S0 of the luminous printing plate, wherein △Q1<△Q2, 1<α1<α2,

[0093] If ΔQ≤ΔQ1, the central control module determines not to adjust the luminous intensity of the luminous printing plate;

[0094] If ΔQ1<ΔQ≤ΔQ2, the central control module determines to use α1 to adjust the luminous intensity of the luminous printing plate;

[0095] If ΔQ>ΔQ2, the central control module determines to use α2 to adjust the luminous intensity of the luminous printing plate;

[0096] The preset image clarity condition is that the image clarity Q of the area to be stamped satisfies Q1<Q≤Q2. Furthermore, the workbox of this embodiment sets a preset first image clarity difference, a preset second image clarity difference, a preset first luminous intensity adjustment coefficient, a preset second luminous intensity adjustment coefficient, and a preset luminous intensity of the luminous printing plate. By adjusting the luminous intensity of the luminous printing plate to the first corresponding luminous intensity value of the luminous printing plate based on the difference between the actual image clarity and the preset image clarity, the effect of inaccurate adjustment of the luminous intensity of the luminous printing plate 5 on the accuracy of stamping is reduced, thereby further improving the safety of stamping.

[0097] Specifically, when the central control module completes the adjustment of the luminous intensity of the luminous printing plate, it determines whether the adjustment of the luminous intensity of the luminous printing plate 5 is reasonable based on the area ratio E of the light blocking area of ​​the document photo captured by the camera. The central control module is provided with a preset first blocking area ratio E1 and a preset second blocking area ratio E2, where E1<E2.

[0098] If E≤E1, the central control module determines that the area ratio of the light blocking region is within the allowable range;

[0099] If E1<E≤E2, the central control module determines that the area ratio of the optical fiber blocking area exceeds the allowable range, calculates the difference ΔE between the actual area ratio of the light blocking area of ​​the document photo and the preset area ratio of the blocking area, and adjusts the luminous intensity of the luminous printing plate to the second corresponding luminous intensity value of the luminous printing plate according to ΔE, setting ΔE=E-E1;

[0100] If E>E2, the central control module preliminarily determines that the seal usage range of the document is lower than the allowable range.

[0101] Furthermore, the working box of this embodiment sets a preset first blocking area ratio and a preset second blocking area ratio, and determines whether the adjustment of the luminous intensity of the luminous printing plate 5 is reasonable based on the area ratio of the light blocking area of ​​the document photo taken by the camera, thereby reducing the impact of excessive adjustment of the luminous intensity of the luminous printing plate 5 on the clarity of the document taken by the camera on the effectiveness of seal monitoring, and further achieving an improvement in the safety of seal use.

[0102] Specifically, the central control module adjusts the luminous intensity of the luminous printing plate to a second corresponding luminous intensity value S' of the luminous printing plate according to the difference between the actual area ratio of the light shading area of ​​the document photo and the preset area ratio of the luminous area under the preset first shading area ratio condition, sets S'=S'×(1+αj) / 2, αj is the second luminous intensity adjustment coefficient, and sets j=3, 4, wherein the central control module is provided with a preset first shading area ratio difference △E1, a preset second shading area ratio difference △E2, a preset third luminous intensity adjustment coefficient α3, and a preset fourth luminous intensity adjustment coefficient α4, wherein △E1<△E2, 0<α3<α4<1,

[0103] If ΔE≤ΔE1, the central control module determines to adjust the luminous intensity of the luminous printing plate to S0;

[0104] If ΔE1<ΔE≤ΔE2, the central control module determines to use α4 to adjust the luminous intensity of the luminous printing plate;

[0105] If ΔE>ΔE2, the central control module determines to use α3 to adjust the luminous intensity of the luminous printing plate;

[0106] The preset first shielding area condition is that the actual area ratio E of the light shielding area of ​​the document photo satisfies E1<E≤E2.

[0107] Furthermore, the working box of this embodiment sets a preset first blocking area ratio difference, a preset second blocking area ratio difference, a preset third luminous intensity adjustment coefficient and a preset fourth luminous intensity adjustment coefficient, and adjusts the luminous intensity of the luminous printing plate to the second corresponding luminous intensity value of the luminous printing plate according to the difference between the actual area ratio of the light blocking area of ​​the document photo and the preset area ratio of the blocking area, thereby reducing the impact on the effectiveness of the supervision of the printing process due to the inaccurate adjustment of the luminous intensity of the luminous printing plate 5, and further achieving an improvement in the safety of printing.

[0108] Specifically, when the central control module completes the adjustment of the side length of the limited stamping area, it determines whether there is a stamping safety risk based on the actual area ratio G of the document to be stamped on the luminous stamping plate 5. The central control module is provided with a preset first area ratio G1 and a preset second area ratio G2, wherein G1<G2.

[0109] If G≤G1, the central control module determines that the actual area ratio of the document to be stamped on the luminous printing plate 5 is within the allowable range;

[0110] If G1<G≤G2, the central control module determines that the actual area ratio of the document to be stamped on the luminous printing plate 5 exceeds the allowable range, calculates the difference △G between the actual area ratio and the preset area ratio, and adjusts the side length of the limited stamping area to the side length of the second corresponding limited stamping area according to △G, setting △G=G-G1;

[0111] If G>G2, the central control module determines that there is a seal security risk and issues a risk investigation notice.

[0112] Furthermore, the working box of this embodiment sets a preset first area ratio and a preset second area ratio, and determines whether there is a safety risk of using seals based on the actual area ratio of the document to be stamped on the luminous printing plate 5, thereby reducing the impact of inaccurate determination of the actual area ratio of the document to be stamped on the luminous printing plate 5 on the safety of using seals, and further achieving an improvement in the safety of using seals.

[0113] Specifically, the central control module adjusts the side length of the restricted printing area to the second corresponding side length La' of the restricted printing area according to the difference between the actual area ratio and the preset area ratio under the preset area ratio condition, sets La'=La'×γp, γp is the second adjustment coefficient of the side length of the restricted printing area, and sets p=3, 4, wherein the central control module is provided with a preset first area ratio difference △G1, a preset second area ratio difference △G2, a preset third restricted printing area side length adjustment coefficient γ3, and a preset fourth restricted printing area side length adjustment coefficient γ4, wherein △G1<△G2, 0<γ3<γ4<1,

[0114] If △G≤△G1, the central control determines to adjust the side length of the limited printing area to La;

[0115] If ΔG1<ΔG≤ΔG2, the central control module determines to use γ4 to adjust the side length of the limited printing area;

[0116] If ΔG>ΔG2, the central control module determines to use γ3 to adjust the side length of the limited printing area;

[0117] The preset area ratio condition is that the actual area ratio G of the document to be stamped on the luminous printing plate 5 satisfies G1<G≤G2.

[0118] Furthermore, the working box of this embodiment sets a preset first area ratio difference, a preset second area ratio difference, a preset third restricted printing area side length adjustment coefficient, and a preset fourth restricted printing area side length adjustment coefficient. By adjusting the side length of the restricted printing area to the side length of the second corresponding restricted printing area according to the difference between the actual area ratio and the preset area ratio, the impact on the effectiveness of printing supervision caused by inaccurate adjustment of the side length of the restricted printing area is reduced, and the security of printing is further improved.
