[0063] Step 101, in response to a stamping instruction for a document to be stamped, an initial image of the document to be stamped is collected; the document to be stamped is placed at a preset stamping document position; pixels in the initial image have at least one pixel type;

[0064] In the embodiment of the present invention, the seal control device may be a portable seal control device, which may be used for the security management of seals. A seal may be installed in the seal control device, and the seal is physically locked inside the seal control device, with the seal surface located inside the seal control device, so that the seal cannot be used to stamp documents that are not authorized by authorized personnel.

[0065] Reference Figure 2 , which shows a schematic diagram of a seal control device provided in an embodiment of the present invention. Figure 2 The interior of the printing control device shown in the figure. The printing control device mainly includes a seal lifting mechanism component, a main control circuit board, a power module and a frame component. Among them, the seal lifting mechanism component can also be called a seal lifting device.

[0066] In an embodiment of the present invention, a user can place the document to be stamped on the desktop, and the location where the document to be stamped is placed can be called the stamped document location. Then, the user can place the portable seal control device in the stamping area of ​​the document to be stamped, and then the user logs in to the seal system through the APP (Application) of the mobile phone, and sends the electronic file of the document to be stamped to the authorized person through the seal system. The authorized person can determine whether to grant authorization for the document to be stamped based on the electronic file. If the authorized person grants authorization for the document to be stamped, the user can then connect to the seal control device through the mobile phone Bluetooth, and the mobile phone APP can send a stamping instruction for the authorized document to be stamped to the seal control device.

[0067] In an embodiment of the present invention, the printing control device can capture an initial image of the document to be stamped in response to a stamping instruction for the document to be stamped, wherein the document to be stamped is placed at a stamping document position, the printing control device is in the stamping area of ​​the document to be stamped, and the document to be stamped has obtained the stamping authorization of the authorized person.

[0068] In the embodiment of the present invention, the document to be stamped includes at least one pixel, and the pixel of the document to be stamped includes at least one pixel type.

[0069] In some embodiments of the present invention, the printing control device further includes an image sensor, a light emitting device and a converging lens; and the collecting of the initial image of the document to be stamped includes:

[0070] Controlling the light emitting device to emit light to the location of the stamped document; the light is reflected at the location of the stamped document to form reflected light; the reflected light is converged by the converging lens to form converged light;

[0071] The image sensor is controlled to acquire the initial image using the converged light.

[0072] Reference Figure 3 , shows a schematic diagram of image acquisition of a printing control device provided in an embodiment of the present invention. The document to be stamped is placed on the WorkSurface, and the frame components of the printing control device include a sensor, a lens, and an LED (Light Emitting Diode). The sensor can be an image sensor or an optical sensor, the lens can be a converging lens, and the light emitting diode is also called a light emitting device.

[0073] Reference Figure 4 , shows a schematic diagram of image acquisition of another printing control device provided in an embodiment of the present invention. The printing control device includes an optical sensor, a light emitting diode, a plane mirror and a converging lens. In the embodiment of the present invention, both the optical sensor and the image sensor can be used to acquire images.

[0074] In the embodiment of the present invention, in response to the stamping instruction for the document to be stamped, the printing control device controls the light emitting device to emit light to the position of the document to be stamped. The light can reach the position of the document to be stamped after multiple reflections of the plane mirror.

[0075] Since the document to be stamped is placed at the position of the document to be stamped, the light will be reflected by the document to be stamped at the position of the document to be stamped, forming a reflected light. When the reflected light reaches the converging lens, the reflected light is converged to form a converging light. The printing controller can control the image sensor or the optical sensor to convert the light signal of the converging light into a digital signal, and then convert the digital signal into the initial image of the document to be stamped.

[0076] In some embodiments of the present invention, the light is red light.

[0077] In an embodiment of the present invention, the light emitted by the light-emitting device can be red light; the image sensor on the printing control device can realize infrared photoelectric detection, collect the initial image of the document to be stamped at the stamping position, and can also continuously collect the image at the stamping position of the document during the process of the printing control device controlling the seal to stamp.

[0078] Step 102, assigning corresponding type data to the at least one pixel type, and acquiring an initial data group corresponding to the initial image based on the type data corresponding to the pixel type;

[0079] In the embodiment of the present invention, the initial image of the document to be stamped that obtains the stamping authorization and is placed at the stamping document position includes at least one pixel point, and the pixel points of the initial image include at least one pixel point type.

[0080] In the embodiment of the present invention, corresponding type data may be allocated to the pixel type, and based on the type data corresponding to the pixel type, an initial data group corresponding to the initial image may be acquired.

[0081] In some embodiments of the present invention, the acquiring, based on the type data corresponding to the pixel type, an initial data group corresponding to the initial image includes:

[0082] Determining initial data corresponding to a pixel point in the initial image based on the type data corresponding to the pixel point type;

[0083] The initial data set is constructed using the initial data.

[0084] In the embodiment of the present invention, the printing control device can determine the pixel type of each pixel in the initial image, and determine the initial data corresponding to each pixel in the initial image according to the type data corresponding to the pixel type. Then, the initial data is used to construct the initial data group.

[0085] In some embodiments of the present invention, the pixel type includes white pixel points and / or black pixel points; and the assigning corresponding type data to the at least one pixel type includes:

[0086] Corresponding type data is allocated to the white pixel point and / or the black pixel point.

[0087] In the embodiment of the present invention, the pixel type of the pixel of the initial image may include white pixel and / or black pixel. In the embodiment of the present invention, corresponding type data may be allocated to the white pixel and / or black pixel.

[0088] In a specific example, the initial image includes only white pixels and black pixels. The printer controller assigns type data 0 to white pixels and type data 1 to black pixels. If the initial image includes only 6 pixels, the initial data group may be "0, 1, 0, 1, 0, 1".

[0089] Step 103, controlling the seal to move, and when the seal face of the seal moves to the position of the stamped document, collecting the target image at the position of the stamped document;

[0090] In the embodiment of the present invention, the seal control device can control the seal to move in response to the seal instruction for the document to be stamped, so that the seal surface moves to the position of the document to be stamped, and stamps the document to be stamped.

[0091] When the seal moves to the position of the stamped document, the seal control device can use the light emitting device, the converging lens and the image sensor to collect the target image at the position of the stamped document. The method of collecting the target image is similar to the method of collecting the initial image, and the present invention will not be repeated here.

[0092] In some embodiments of the present invention, the seal control device further includes a seal lifting device and a drive motor; the control of the seal to move includes:

[0093] By controlling the driving motor, the seal lifting device is controlled to move the seal.

[0094] In an embodiment of the present invention, the printing control instrument further includes a seal lifting device, a main control circuit board, a drive motor and a power module. The power module is used to supply power for the operation of the printing control instrument, and the main control circuit board may include a control chip, and the control operation of the printing control instrument can be performed by the control chip in the main control circuit board.

[0095] In the embodiment of the present invention, when controlling the movement of the seal, the seal control device can use the main control circuit board to control the driving motor, and manipulate the seal lifting device to move, so that the seal moves, and the seal face moves to the position of the document to be stamped. After the seal face moves to the position of the document to be stamped, the driving motor is controlled to stop running, and the target image is captured by the image sensor.

[0096] Step 104, acquiring a target data group corresponding to the target image based on the type data corresponding to the pixel type;

[0097] In the embodiment of the present invention, the pixel type of the target image at the stamped document position is the same as the pixel type corresponding to the initial image of the document to be stamped. The pixel points of the target image may also include white pixels and / or black pixels.

[0098] In an embodiment of the present invention, the printing control device can determine the pixel type of each pixel in the target image, and determine the target data corresponding to each pixel in the target image according to the type data corresponding to the pixel type, and construct a target data group using the target data.

[0099] In a specific example, the target image includes only white pixels and black pixels. The printer controller assigns type data 0 to white pixels and type data 1 to black pixels. If the target image includes only 6 pixels, the target data group may be "1, 1, 1, 1, 0, 1".

[0100] Step 105, by comparing the initial data group and the target data group, determining whether the document to be stamped at the stamped document position has been replaced and / or moved;

[0101] In an embodiment of the present invention, the initial image and the target image can be compared by comparing the initial data group and the target data group to determine whether the file to be stamped at the stamping file position is moved or replaced by other files during the process in which the seal control device controls the seal to move until the seal surface moves to the stamping file position.

[0102] In the embodiment of the present invention, the printing control device can also determine the initial position of the document to be stamped in the initial image according to the initial image, and determine the target position of the document in the target image according to the target image, and determine whether the document has been moved according to the initial position and the target position.

[0103] In some embodiments of the present invention, the step of comparing the initial data set with the target data set to determine whether the document to be stamped at the stamped document position has been replaced and / or moved includes:

[0104] calculating an error between the initial data set and the target data set;

[0105] When the error exceeds a preset error range, it is determined that the document to be stamped is replaced and / or moved.

[0106] In the embodiment of the present invention, the error between the initial data set and the target data set can be calculated. When the error exceeds the preset error range, it can be determined that during the process in which the seal is controlled by the seal control device to move until the seal surface moves to the position of the stamped document, the document to be stamped is replaced and / or moved, and there is a risk that the authorized document to be stamped is replaced by a document without authorization. The preset error range is determined based on a large number of experiments.

[0107] Reference Figure 5 , shows a schematic diagram of comparison between an initial image and a target image provided in an embodiment of the present invention. Figure 5 The first image in the image is the initial image, and the second image is the target image. Both the initial image and the target image include only white pixels and black pixels. The error between the initial data group corresponding to the initial image and the target data group corresponding to the target image can be calculated to achieve the comparison between the initial image and the target image, and determine whether the document to be stamped at the stamping document position is moved or replaced by other files in the process of the seal control instrument controlling the seal to move until the seal surface moves to the stamping document position.

[0108] In the embodiment of the present invention, the absolute error or mean square error between the initial data set and the target data set may be calculated, and the absolute error or mean square error may be used to determine whether the document to be stamped at the stamped document position is moved and / or replaced.

[0109] Step 106, when the document to be stamped is replaced and / or moved, control the printing control device to issue an alarm.

[0110] In an embodiment of the present invention, the printing control device may include a buzzer. When the printing control device determines that the document to be stamped at the stamping document position is replaced and / or moved, and the printing control device determines that the authorized document to be stamped is at risk of being replaced by a document without authorization, the printing control device may control the buzzer to sound an alarm, and record the event that the document to be stamped is replaced and / or moved in a preset event log.

[0111] In an embodiment of the present invention, a preset seal is installed in the seal control device, and the seal face is located inside the seal control device. In response to a seal instruction for a document to be sealed, an initial image of the document to be sealed is collected; the document to be sealed is placed at a preset seal document position; the pixels in the initial image have at least one pixel type; corresponding type data is assigned to at least one pixel type, and based on the type data corresponding to the pixel type, an initial data group corresponding to the initial image is obtained; the seal is controlled to move, and when the seal face moves to the seal document position, a target image at the seal document position is collected; based on the type data corresponding to the pixel type, a target data group corresponding to the target image is obtained; by comparing the initial data group and the target data group, it is determined whether the document to be sealed at the seal document position is replaced and / or moved; in the case where the document to be sealed is replaced and / or moved, the seal control device is controlled to issue an alarm. By comparing the initial data group and the target data group, it is determined whether the document to be stamped at the stamped document position has been replaced and / or moved, thereby determining whether there is a risk that the authorized document to be stamped at the stamped document position is replaced by an unauthorized document. This realizes the security detection of the seal control device during the use of the seal, so that the authorized personnel know whether the document to be stamped at the stamped document position has been moved or replaced by other files during the process of the seal control device controlling the movement of the seal until the seal surface moves to the stamped document position, thereby improving the security effect of using the seal.
