The current mainstream method is to connect the OCR scanner to an external computer or other device through a network, serial port or other interface to modify the target matching characters of the OCR scanner. This method is difficult to implement quickly and conveniently for some factory sites without computers, and this method must introduce external equipment, which makes the configuration process complicated and increases cost overhead.

[0023] See also Figure 1 An OCR code scanning system of the present invention includes an OCR character recognition module 10, a two-dimensional code recognition module 20 and an information acquisition module 30 for acquiring a two-dimensional code configuration code. The two-dimensional code configuration code is generated by an OCR target matching character. The input end of the two-dimensional code recognition module 20 is electrically connected to the information acquisition module 30 to acquire the two-dimensional code configuration code. The output end of the two-dimensional code recognition module 20 is electrically connected to the OCR character recognition module 10 to transmit the OCR target matching character corresponding to the two-dimensional code configuration code to the OCR character recognition module 10.

[0024] The OCR code scanning system of this embodiment is provided with a two-dimensional code recognition module 20 and an information acquisition module 30 for acquiring a two-dimensional code configuration code. The two-dimensional code configuration code is generated by an OCR target matching character. The input end of the two-dimensional code recognition module 20 is electrically connected to the information acquisition module 30, and the output end of the two-dimensional code recognition module 20 is electrically connected to the OCR character recognition module 10. This facilitates the conversion of the two-dimensional code configuration code into an OCR target matching character through the two-dimensional code recognition module 20. The structure is simple, and the target matching characters of the OCR code scanning system can be accurately modified. Moreover, the modification of the target matching characters can be achieved without introducing an external configuration device, and the cost is low.

[0025] See also Figure 2 , Figure 2 FIG. 1 is a schematic diagram of the structure of an OCR code scanning system according to another embodiment of the present invention. Figure 1 Compared with the embodiment in the previous embodiment, in this embodiment, the OCR character recognition module 10 includes a character library 11, and the input end of the character library 11 is electrically connected to the output end of the two-dimensional code recognition module 20 to receive the OCR target matching character, and modify and update according to the OCR target matching character.

[0026] The OCR character recognition module 10 also includes a character recognition submodule 12 . The output end of the character library 11 is electrically connected to the input end of the character recognition submodule 12 , so that the character recognition submodule 12 can use the character library 11 to perform character recognition on the image acquired by the OCR character recognition module 10 .

[0027] The OCR code scanning system of this embodiment transmits the target matching characters to the character library 11 through the two-dimensional code recognition module 20, so that the character library 11 can be modified and updated, thereby ensuring the accuracy of character recognition.

[0028] See also Figure 3 , Figure 3 FIG. 1 is a schematic diagram of the structure of an OCR code scanning system according to the third embodiment of the present invention. Figure 2Compared with the embodiment, in this embodiment, the OCR scanning system also includes a control module 40, the output end of the control module 40 is electrically connected to the input end of the two-dimensional code recognition module 20, the output end of the control module 40 is electrically connected to the input end of the OCR character recognition module 10, and the output end of the control module 40 is electrically connected to the input end of the information acquisition module 30, so as to be able to control the working status of each module.

[0029] When the information acquisition module 30 is only used to acquire the QR code configuration code, the OCR scanning system also includes an image acquisition module 50, the input end of the image acquisition module 50 is electrically connected to the control module 40 so as to control the working state of the image acquisition module 50 through the control module 40, and the output end of the image acquisition module 50 is electrically connected to the input end of the OCR character recognition module 10 so as to perform character recognition through the OCR character recognition module 10.

[0030] In order to switch the working mode, the OCR code scanning system further includes a first selection module 60 , and the output end of the first selection module 60 is electrically connected to the input end of the control module 40 .

[0031] When the first selection module 60 corresponds to the character modification mode, the control module 40 controls the information acquisition module 30 and the QR code recognition module 20 to be in a working state, and controls the image acquisition module 50 and the OCR character recognition module 10 to be in a non-working state. At this time, the information acquisition module 30 obtains the QR code configuration code and transmits the QR code configuration code to the QR code recognition module 20. The QR code recognition module 20 decodes the QR code configuration code to obtain the OCR target matching characters and then transmits the OCR target matching characters to the character library 11. The character library 11 uses the received OCR target matching characters to complete the modification and update within it.

[0032] When the first selection module 60 corresponds to the character recognition mode, the control module 40 controls the information acquisition module 30 and the QR code recognition module 20 to be in an inoperative state, and controls the OCR character recognition module 10 and the image acquisition module 50 to be in an operating state. At this time, the image acquisition module 50 acquires the image to be recognized and transmits the image to be recognized to the OCR character recognition module 10, and the character recognition submodule 12 uses the character library 11 to perform character recognition on the image to be recognized.

[0033] The working state and non-working state here are relative to the main functions of each module. For example, the image acquisition module 50 is in a working state when it acquires an image, and is in a non-working state when it does not acquire an image. The OCR character recognition module 10 is in a working state when it performs character recognition, and is in a non-working state when it does not perform character recognition.

[0034] See also Figure 4 , Figure 4 FIG. 4 is a schematic diagram of the structure of an OCR code scanning system according to the fourth embodiment of the present invention. Figure 3 Compared with the embodiment in the embodiment, in this embodiment, the information acquisition module 30 is also used to obtain the recognition image, that is, the information acquisition module 30 obtains the QR code configuration code image and the image to be recognized by, for example, taking a photo. At this time, only the information acquisition module 30 is needed to obtain all the information to be recognized, and the structure is simpler. The output end of the information acquisition module 30 is electrically connected to the input end of the OCR character recognition module to transmit the image to be recognized to the OCR character recognition module.

[0035] In order to switch the working mode, the OCR code scanning system further includes a second selection module 60 ′, and the output end of the second selection module 60 ′ is electrically connected to the input end of the control module 40 .

At this time, the information acquisition module 30 obtains the two-dimensional code configuration code image and transmits the two-dimensional code configuration code to the two-dimensional code recognition module 20. The two-dimensional code recognition module 20 decodes the two-dimensional code configuration code to obtain the OCR target matching characters and then transmits the OCR target matching characters to the character library 11. The character library 11 uses the received OCR target matching characters to complete the modification and update inside it.

[0037] When the second selection module 60' corresponds to the character recognition mode, the control module 40 controls the QR code recognition module 20 to be in a non-working state, and controls the OCR character recognition module 10 and the information acquisition module 30 to be in a working state. At this time, the information acquisition module 30 obtains the image to be recognized and transmits the image to be recognized to the OCR character recognition module 10, and the character recognition submodule 12 uses the character library 11 to perform character recognition on the image to be recognized.

[0038] As above, the working state and non-working state here are also relative to the main functions of each module.

[0039] See also Figure 5 , Figure 5 FIG. 5 is a schematic diagram of the structure of an OCR code scanning system according to the fifth embodiment of the present invention. Figure 4 Compared with the embodiment in the above description, in this embodiment, the OCR code scanning system does not realize the working mode switching by selecting a module, but realizes the working mode switching by judging the image type. When the image type is a QR code, it corresponds to the character modification mode, and when the image type is not a QR code, it corresponds to the character recognition mode.

[0040] The OCR code scanning system includes an image type determination module 70. The output end of the information acquisition module 30 is electrically connected to the input end of the image type determination module 70 to transmit the recognized image to the image type determination module 70. The output end of the image type determination module 70 is electrically connected to the input end of the control module 40 to transmit the image type to the control module 40.

[0041] When the image type is a QR code, the control module 40 controls the QR code recognition module 20 to be in a working state and controls the OCR character recognition module 10 to be in a non-working state. At this time, the information acquisition module 30 obtains the QR code configuration code image and transmits the QR code configuration code to the QR code recognition module 20. The QR code recognition module 20 decodes the QR code configuration code to obtain the OCR target matching characters and then transmits the OCR target matching characters to the character library 11. The character library 11 uses the received OCR target matching characters to complete the modification and update within it.

[0042] When the image type is not a QR code, the control module 40 controls the QR code recognition module 20 to be in an inoperative state and controls the OCR character recognition module 10 to be in an operating state. At this time, the information acquisition module 30 acquires the image to be recognized and transmits the image to be recognized to the OCR character recognition module 10, and the character recognition submodule 12 uses the character library 11 to perform character recognition on the image to be recognized.

[0043] Preferably, the OCR code scanning system also includes a display module (not shown in the figure), and the output end of the QR code recognition module 20 and the output end of the OCR character recognition module 10 are electrically connected to the display module to display the corresponding content to facilitate the detection of whether there are errors in the content.

[0044] An OCR code scanning system of the present invention is provided with a two-dimensional code recognition module and an information acquisition module for acquiring a two-dimensional code configuration code. The two-dimensional code configuration code is generated by an OCR target matching character. The input end of the two-dimensional code recognition module is electrically connected to the information acquisition module, and the output end of the two-dimensional code recognition module is electrically connected to the OCR character recognition module. It is convenient to convert the two-dimensional code configuration code into an OCR target matching character through the two-dimensional code recognition module. The system has a simple structure, can accurately modify the target matching character of the OCR code scanning system, and can realize the modification of the target matching character without introducing an external configuration device.
