Detailed Description
The foregoing and other objects, features and advantages of the invention will be apparent from the following more particular description of the invention, as illustrated in the accompanying drawings. Like reference numerals refer to like parts throughout the several views of the drawings. The drawings are not intended to be drawn to scale, emphasis instead being placed upon illustrating the principles of the invention.
Example 1
Referring to fig. 1, a seal image acquisition device of the present invention will be described. The seal image acquisition device of the invention comprises a control module, a detection module, an image acquisition module, a storage module and a communication module, and of course, other modules which are necessary for the system, such as a power supply module for supplying power to each module, are also included, and are not shown in the drawings, but are not essential to the invention. The detection module, the image acquisition module, the storage module and the communication module are all connected with the control module. It should be understood by those skilled in the art that "connected" may be either physical or wireless, and the invention is not limited to a particular manner of connection.
The detection module is used for acquiring a seal signal of the seal copied on the paper and sending the seal signal to the control module. The paper in the invention can be various documents, bills and other paper documents needing signature and stamping. The seal may be a stamp, fingerprint, signature, etc. Taking a seal as an example, the detection module can be used for acquiring a seal signal of the seal copied on a paper piece, and the seal signal can be acquired through a sensor, wherein the sensor can be a pressure sensor, a travel switch, a photoelectric switch and the like. The following describes in detail how the signature signal is obtained by taking the pressure switch as an example. In the invention, the pressure sensor can be paved in the base 2 in fig. 1, the bill to be stamped is arranged on the base 2, when the hand-held stamp stamps on the bill, the pressure on the stamp is increased, the pressure sensor can detect the change of the pressure, and the detected change signal of the pressure is a stamp signal which indicates that the stamping on the bill is finished. For example, the photoelectric sensor can be an infrared sensor, in the stamping process, the hand or the stamp can shield the infrared signal, the output voltage of the infrared sensor is changed, and the change signal is a seal signal. For seal marks in the forms of fingerprints, signatures and the like, similar to the seal marks, pressure can be generated on paper in the process of signing or pressing fingerprints, and a pressure signal can be acquired through a pressure sensor, so that a seal mark signal is obtained.
And the control module is used for sending an image acquisition instruction to the image acquisition module after receiving the seal signal. The detection module sends the acquired seal signal to the control module, the control module judges that the seal is copied on a paper piece after receiving the seal signal, and the control module sends an image acquisition instruction to the image acquisition module after receiving the pressure signal sent by the pressure sensor by taking stamping as an example. For the infrared sensor, the control module sends an image acquisition instruction to the image acquisition module after receiving the voltage signal. Further, because of different forces of stamping, signing or fingerprint pressing, the generated pressure signals are different, and the definition of the seal left on the surface of the paper is different correspondingly, in general, the seal is clearer when the force is larger, otherwise, the seal is not clear when the force is smaller. In order to obtain a clear seal image, a threshold signal can be preset, and an image acquisition instruction is sent to the image acquisition module when the detected seal signal is greater than or equal to the threshold signal. This threshold signal is pre-stored in the memory module. Taking a pressure sensor as an example, the pre-stored pressure threshold value is 3, the pressure value (seal signal) detected by the detection module is 1, the seal stamping force is smaller, the control module does not send an image acquisition instruction, and the control module can send a prompt through a loudspeaker and the like to prompt a worker to stamp again. If the pressure value (seal signal) detected by the detection module is 5 and is larger than the pre-stored pressure threshold value 3, the control module sends an image acquisition instruction, and the image acquisition device is started to acquire the paper image.
The image acquisition module is used for acquiring the image of the paper with the copied seal according to the image acquisition instruction. The image acquisition module may employ a camera. The image acquisition module stores the acquired image in the storage module through the control module after acquiring the image signal, and the storage module can adopt a magnetic disk and E 2 PROM, memory chip, flash disk, memory card, etc. The stored image includes the acquisition date, name, etc. of the image. Further, the seal image can be prestored in the storage module, the control module recognizes the collected image after the image collection of the paper with the copied seal is completed, the seal image in the collected image is extracted, and the extracted seal image is compared with the prestored seal image to judge whether the current seal is legal or not. Specifically, when the extracted seal image is inconsistent with the pre-stored seal image, judging that the currently used seal is illegal, and sending out an acousto-optic prompt; and if the two images are consistent, judging the seal impression method, and storing the acquired images.
The control module can communicate with the remote monitoring module through the communication module, and can receive the instruction of the remote monitoring module through the communication module or send the stored image to the remote monitoring module. The further control module may send the stored image to the monitoring module in response to the get image instruction sent by the monitoring module; or the control module sends the images acquired in the time to the monitoring module every preset time. The monitoring module can adopt a PC, a mobile phone and the like. The communication module can adopt communication modes such as GPRS, bluetooth, wiFi, zigbee and the like. Taking a mobile phone as an example, communication can be established between the mobile phone and the control module through GPRS, a manager can send an instruction signal for acquiring an image to the control module through the mobile phone, the instruction signal can comprise the date, the name and the like of the image to be acquired, the control module responds to the instruction to search a corresponding image in the storage module after acquiring the instruction, and after the image is searched, the image is sent to a mobile phone terminal of the manager through the communication module, so that the manager can check the picture after the file is stamped at any time and any place in real time, and the seal service condition is monitored. Or the newly acquired images can be sent to the mobile phone of the manager every 5 hours, so that the manager can obtain the images of all the stamping files at regular time, and the stamp service condition can be monitored conveniently.
The seal image acquisition device detects whether seal copying occurs or not through the detection module, automatically completes image acquisition of paper after seal copying is detected, and can send the image acquisition to a remote manager. Meanwhile, a manager can check the picture of the stamped file at any time and any place in real time, and the stamp service condition can be monitored.
Example 2
Referring to fig. 3, this embodiment focuses on differences from embodiment 1, and the same points are not repeated. The display module, the first timing module and the second timing module which are connected with the control module are added in the embodiment. The display module may employ a liquid crystal display. The first and second timing modules may be timers internal or external to the control module.
The first timing module is used for starting first timing after the control module receives the seal signal, and the control module sends an image acquisition instruction to the image acquisition module after the first timing is finished. After the detection module detects the seal signal, the seal or the hand is still positioned on the paper, and if the image acquisition is started, the image of the seal or the hand is acquired, so that the seal file is blocked, and the image acquisition is not satisfactory. The invention sets the first timing module, after obtaining the seal signal, starts the first timing, during this period, the staff will remove the hand and seal from the paper surface, and starts the image collection after the first timing is finished, thus can obtain the image meeting the requirements. The duration of the first timer may be 3S, 5S, 10S, etc.
The display module is used for displaying the image acquired by the current image acquisition module, the display module can display the image acquired by the current image acquisition module on the display screen after the image acquisition is completed, a confirmation dialog box can be popped up on the display screen at the moment, after a worker clicks 'confirm', the worker is shown to confirm that the acquired image meets the requirement, and then the image is sent to the storage module for storage. Furthermore, if the operator needs to click to confirm each time, the method is obviously complicated, and therefore, the invention further provides a second timing module, the second timing module is started after the image acquisition module finishes image acquisition, the second timing is started, and the image is sent to the storage module for storage after the second timing is finished. For example, when the display module displays the currently acquired image, a second timing is displayed on the screen in a countdown mode, and after the second timing is finished, the image is stored when the operator considers that the acquired image has no problem.
According to the embodiment, the display module, the first timing module and the second timing module are added, so that the collected images can be checked in fact, shielding of the images is avoided, the quality of the collected images is greatly improved, and all the collected images can meet the requirements.
Example 3

The wireless chip in the seal can communicate with the control module through the communication module, so that the control module can read the identification code of the seal in the image acquisition process, and store the identification code together with the image, thereby facilitating statistics and management of the use condition of the seal. The communication between the wireless chip and the control module can adopt Bluetooth, wiFi, zigbee and other modes. Taking a seal as an example, after the detection module detects a seal signal, the control module sends an instruction for acquiring a seal serial number to the wireless chip through the communication module, the wireless chip responds to the instruction and sends a prestored serial number to the control module, and after image acquisition is completed, the control module stores the serial number together with an image, for example, the image can be commanded to be stored in a form of time plus serial number, so that the seal stamped by a current file can be conveniently identified, and statistics and management on the use condition of the seal are also facilitated. Of course, the information exchange process between the wireless chip and the control module may include common techniques for authentication, encryption, decryption, etc. of the information, which will not be described again.
