[0048] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.
[0049] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.
[0050] This invention provides a display refresh system for electronic paper. Figure 1 This is a schematic diagram of the structure of an electronic paper display refresh system according to an embodiment of the present invention, with reference to... Figure 1 An electronic paper display refresh system includes:
[0051] Read / write module 1, first transmission module 2, second transmission module 3, receiving module 4, control module 5, and electronic paper 6;
[0052] The read / write module 1 is connected to the first transmission module 2, and the second transmission module 3 is connected to the first end of the receiving module 4. The read / write module 1 is used to obtain the current on-site work information, determine the quick query information that needs to be changed based on the on-site work information, and transmit the quick query information to the receiving module 4 through the first transmission module 2 and the second transmission module 3, and / or determine the change area to be updated, input the change data in the change area to be updated, and transmit the change data of the change area to be updated to the receiving module 4 through the first transmission module 2 and the second transmission module 3.
[0053] The second end of the receiving module 4 is connected to the first end of the control module 5, and the second end of the control module 5 is connected to the electronic paper 6. The receiving module 4 is used to receive quick query information and / or change data of the change area to be updated, and transmit the quick query information and / or change data of the change area to be updated to the control module 5. The control module 5 is used to generate a quick query code based on the quick query information, and refresh the electronic paper 6 based on the quick query code and / or change data of the change area to be updated.
[0054] Specifically, after determining the display template of the electronic paper 6 based on its application scenario (i.e., the fixed area and its information, as well as the changed area and its initial information), the read / write module 1 acquires the current on-site work information in real time. This on-site work information includes the industrial production process. Based on the current on-site work information and the pre-determined correspondence between the on-site work information and the quick query information, the module determines the quick query information that needs to be changed and transmits the generated quick query information to the receiving module 4 via the first transmission module 2 and the second transmission module 3. When it is necessary to change the data in one or more changed areas, the changed area to be updated can be manually determined on the read / write module 1, and the changed data can be entered at the location of the changed area to be updated on the read / write module 1. Then, the read / write module 1 can transmit the changed data of the area to be changed to the receiving module 4 via the first transmission module 2 and the second transmission module 3.
[0055] If the receiving module 4 only receives quick query information, it can directly transmit the received quick query information to the control module 5. In this case, the control module 5 generates a quick query code based on the quick query information and updates the generated quick query code in the display area of the quick query code. The quick query code can be a QR code, barcode, etc., and this embodiment of the invention does not impose any restrictions on this. If the receiving module 4 only receives change data for one or more change areas, it can directly transmit the received change data for one or more change areas to the control module 5. In this case, the control module 5 can update the data of the change areas on the electronic paper 6 that need to be updated based on the received change data. If the receiving module 4 receives both quick query information and change data for one or more change areas simultaneously, it transmits both the quick query information and the change data for one or more change areas to the control module 5 simultaneously, and the control module 5 updates the quick query code and data of the change areas on the electronic paper 6 that need to be updated.
[0056] The electronic paper display refresh system provided in this embodiment of the invention determines the quick query information to be changed, the change area to be updated, and the corresponding change data of the change area through the read / write module 1. The quick query information to be changed, the change area to be updated, and the corresponding change data of the change area to be updated are transmitted to the control module 5 through the first transmission module 3, the second transmission module 4, and the receiving module 5. The control module 5 generates a quick query code based on the received quick query information and refreshes the electronic paper 6 by combining it with the received change data of the change area to be updated. By setting the quick query code generation process within the control module 5, compared with the prior art where the quick query code is generated before being transmitted to the second transmission module 3 and then transmitted to the control module 5, the amount of data transmitted from the read / write module 1 to the control module 5 is reduced, effectively reducing the time for refreshing the electronic paper 6.
[0057] Furthermore, Figure 2 This is a schematic diagram of another electronic paper display refresh system provided according to an embodiment of the present invention, with reference to... Figure 2 The read / write module includes a host computer 11 and a reader / writer 12;
[0058] The host computer 11 is connected to the first end of the reader 12, and the second end of the reader 12 is connected to the first transmission module 2. The host computer 11 is used to obtain the current field work information, determine the quick query information that needs to be changed based on the field work information, and transmit the quick query information to the receiving module 4 through the reader 12, the first transmission module 2, and the second transmission module 3.
[0059] The reader 12 is used to determine the change area to be updated, input change data in the change area to be updated, and transmit the change data of the change area to be updated to the receiving module 4 through the first transmission module 2 and the second transmission module 3.
[0060] Specifically, after determining the display template of the electronic paper 6 based on its application scenario (i.e., the fixed area and its information, as well as the changed area and its initial information), the host computer 11 acquires the current on-site work information in real time. Based on this information and the pre-determined correspondence between the on-site work information and the quick query information, it determines the quick query information that needs to be changed and transmits the generated quick query information to the receiving module 4 via the reader / writer 12, the first transmission module 2, and the second transmission module 3. When it is necessary to change the data in one or more changed areas, the user can manually determine the area to be updated on the reader / writer 12 and input the change data at the location of the area to be updated on the reader / writer 12. The reader / writer 12 then transmits the change data of the area to be changed to the receiving module 4 via the first transmission module 2 and the second transmission module 3.
[0061] Furthermore, the host computer is used for:
[0062] Based on the application scenarios of electronic paper, fixed areas and variable areas are divided;
[0063] Initialize the data writing process for the content of the fixed area and the content of the changed area to generate the initial display data for the electronic paper.
[0064] The initial display data of the electronic paper is transmitted to the control module through the reader, the first transmission module, the second transmission module, and the receiving module.
[0065] Specifically, based on the application scenario of the electronic paper, the content to be displayed is divided into fixed and variable areas. The content of the fixed and variable areas is clearly defined, and initial data is written into both areas to generate initial electronic paper display data. This initial display data is then transmitted to the control module for storage via a reader / writer, a first transmission module, a second transmission module, and a receiving module. The application scenarios of the electronic paper and the content to be displayed in these scenarios include: serving as an industrial equipment status dashboard, displaying real-time temperature, real-time pressure, alarm status, etc.; serving as a material tracking tag, displaying order number, location, status, etc.; or serving as a medical asset display tag, displaying long-term device ID, department, expiration date, etc. For example, this embodiment of the invention uses a PCB turnover box as an example for detailed description, as follows: Figure 3This is a schematic diagram illustrating the division of a fixed area and a variable area in a PCB turnover box according to an embodiment of the present invention. (Refer to...) Figure 3 First, the display area of the electronic paper can be divided according to the application scenario in the PCB turnover box, and then a fixed area can be determined based on the divided display area. Figure 3 The area highlighted in red is the changed area. These changed areas are also numbered. When data in one or more of these areas needs to be changed, only the number of the changed area to be updated and the content to be changed need to be transmitted. Compared to existing technologies that require transmitting the coordinate location information of the changed areas, this reduces the amount of data transmitted from the host computer to the control module, effectively reducing the time required to refresh the electronic paper. Furthermore, by numbering the changed areas, the number of changed areas is limited, preventing a large number of changed areas from affecting the refresh effect of the electronic paper.
[0066] The host computer can also update the changes in one or more areas of the electronic paper based on real-time acquired industrial production data. For example, Figure 4 This is a schematic diagram illustrating the display content during an SMT process according to an embodiment of the present invention. Figure 5 This is a schematic diagram of the display content during an AOI process according to an embodiment of the present invention, for reference. Figures 4-5 When the product moves from the SMT process to the AOI process, the batch number changes from QRT25-0522-01 to QRT25-0527-01, and the production date changes from 2025-05-22 to 2025-05-27. All other information remains unchanged.
[0067] Furthermore, the host computer is also used for:
[0068] The encoding compression dot matrix library is customized according to the content of the changed area; wherein, the encoding compression dot matrix library includes at least one of the following: the correspondence between encoding and character, the correspondence between encoding and Chinese character, and the correspondence between encoding and custom image;
[0069] The encoded compressed dot matrix library is transmitted to the control module through a reader / writer, a first transmission module, a second transmission module, and a receiving module.
[0070] Specifically, an encoded compressed dot matrix library can be set according to the characters, Chinese characters, custom images, etc. contained in the changed area. This allows for customized settings of the most concise encoding information for different application scenarios, reducing the amount of data transmitted and thus reducing the transmission time at the same rate. The encoded compressed dot matrix library is then transmitted to the control module via a reader / writer, a first transmission module, a second transmission module, and a receiving module. Furthermore, the customized compressed dot matrix library set according to the application scenario can avoid using the content in the character chip, thus eliminating the limitations of the character chip. During the process of burning the customized encoded compressed dot matrix library to the control module, the reduced content reduces input costs. For example, this embodiment of the invention uses a PCB turnover box as an application scenario for electronic paper for detailed description, as follows: Figure 6 This is a schematic diagram illustrating the correspondence between encoding and characters according to an embodiment of the present invention. (Refer to...) Figure 6 Since the content to be updated in the updated area only involves common symbols such as characters and numbers, it can be done as follows: Figure 6 All the characters and numbers shown are programmed into the control module. If GB2312 encoding is used, it requires two bytes; however, if a custom encoding is used, since the number of characters does not exceed 255, only one byte is needed to identify the encoded information. For example... Figure 6 As shown, to implement "!", simply specify the region and transmit the corresponding code 1. Alternatively, a suitable encoding compression dot matrix library can be determined based on the required characters, and the library can be compressed to obtain a smaller amount of transmitted data and storage space. For example, Figure 7 This is a schematic diagram illustrating the conversion between dot matrix and compressed information according to an embodiment of the present invention. (Refer to...) Figure 7 It can compress the dot matrix number 1 and convert it into compressed information corresponding to the dot matrix number 1.
[0071] Furthermore, Figure 8 This is a schematic diagram of the structure of another electronic paper display refresh system according to an embodiment of the present invention, with reference to... Figure 8 The control module includes a storage unit 51, an encoding generation unit 52, and an information update unit 53;
[0072] The second end of the receiving module 4 is connected to the first end of the storage unit 51, the second end of the storage unit 51 is connected to the first end of the encoding generation unit 52, the second end of the encoding generation unit 52 is connected to the first end of the information update unit 53, and the third end of the storage unit 51 is connected to the second end of the information update unit 53. The storage unit 51 is used to receive quick query information and change data of the change area to be updated, transmit the quick query information to the encoding generation unit 52, and transmit the change data of the change area to be updated to the information update unit 53. The encoding generation unit 52 is used to receive quick query information, generate quick query code according to the quick query information, and transmit the quick query code to the information update unit 53.
[0073] The third end of the information update unit 53 is connected to the electronic paper 6. The information update unit 53 is used to refresh the electronic paper 6 according to the quick query code and the change data of the change area to be updated.
[0074] Specifically, after receiving the fast query information, the storage unit 51 transmits the received fast query information to the encoding generation unit 52. The encoding generation unit 52 can be an encoding drawing engine integrated within the control module. The encoding generation unit 52 can then generate fast query codes within the control module based on the received fast query information, and transmit these codes to the information update unit 53 to refresh the electronic paper 6. Instead of generating coded pixel information on the read / write module 1 and then transmitting it to the electronic paper 6 via the first transmission module 2, the second transmission module 3, and the receiving module 4 for refreshing, the data transmission volume is larger, thus affecting the refresh rate of the electronic paper 6. For example, this embodiment of the invention uses a PCB turnover box as an application scenario for the electronic paper in a detailed description, as follows: Figure 3 and Figure 4 As shown, the fast query code in area 10 is not the pixel information transmitted by the host computer, but the information that needs to be quickly queried and displayed by the host computer. It is generated in real time by the code generation unit 52 in the control module, which is convenient for workers and automated equipment to read in real time.
[0075] The storage unit 51 directly transmits the received change data of the changed area to be updated to the information update unit 53, so that the electronic paper 6 can be refreshed by the information update unit 53.
[0076] Furthermore, Figure 9 This is a schematic diagram of the structure of another electronic paper display refresh system according to an embodiment of the present invention, with reference to... Figure 9 The electronic paper display refresh system also includes:
[0077] Energy supply module 7;
[0078] The first end of the energy supply module 7 is connected to the second transmission module 3, the second end of the energy supply module 7 is connected to the receiving module 4, and the third end of the energy supply module 7 is connected to the control module 5.
[0079] The power supply module 7 is used to receive the radio frequency signal transmitted by the second transmission module 3 and convert the radio frequency signal into an electrical signal to power the receiving module 4 and the control module 5.
[0080] Specifically, the energy supply module 7 performs radio frequency field coupling processing on the radio frequency signal transmitted by the second transmission module 3 to convert the radio frequency signal transmitted by the second transmission module 3 into an electrical signal to power the receiving module 4 and the control module 5.
[0081] Furthermore, the control module is used to feed back the update status of the electronic paper to the reader through the receiving module, the second transmission module and the first transmission module, so that the reader can display the update status of the electronic paper.
[0082] The update status of e-paper includes two types: update failure and update success.
[0083] Specifically, the control module sends one of the two update states—failure or success—to the reader via the receiving module, the second transmission module, and the first transmission module. The reader then displays the update status of the electronic paper, allowing staff to check the update status at any time.
[0084] Furthermore, the reader / writer is used for:
[0085] When the update status of the received electronic paper is "update failed", the previously transmitted quick query information and / or the change data of the changed area to be updated are retransmitted to the control module.
[0086] Specifically, if the reader receives an update status of "update failed" for the electronic paper, it will retransmit the quick query information of the update failure and / or the change data of the area to be updated to the control module to refresh the electronic paper again. If multiple refreshes result in update failure, an alarm will be triggered to alert staff that there is an anomaly in the electronic paper display refresh system, requiring timely handling.
[0087] Furthermore, the first transmission module includes a first antenna;
[0088] The second transmission module includes a second antenna.
[0089] This invention provides a display refresh method for electronic paper. Figure 10 This is a flowchart of an electronic paper display refresh method according to an embodiment of the present invention, see reference. Figure 10 Electronic paper display refresh methods include:
[0090] S110, the read / write module obtains the current on-site work information, determines the quick query information that needs to be changed based on the on-site work information, and transmits the quick query information to the receiving module through the first transmission module and the second transmission module, and / or determines the change area to be updated, inputs the change data in the change area to be updated, and transmits the change data of the change area to be updated to the receiving module through the first transmission module and the second transmission module.
[0091] S120, The receiving module receives quick query information and / or change data of the change area to be updated, and transmits the quick query information and / or change data of the change area to be updated to the control module.
[0092] S130, The control module generates a quick query code based on the quick query information, and refreshes the electronic paper based on the quick query code and / or the change data of the change area to be updated.
[0093] The electronic paper display refresh method provided in this invention determines the quick query information to be changed, the area to be updated, and the corresponding change data of the area to be updated through a read / write module. The quick query information, the area to be updated, and the corresponding change data are then transmitted to a control module via a first transmission module, a second transmission module, and a receiving module. The control module generates a quick query code based on the received quick query information and refreshes the electronic paper by combining it with the received change data of the area to be updated. By setting the quick query code generation process within the control module, compared to the prior art where the quick query code is generated before being transmitted to the second transmission module and then transmitted to the control module, the amount of data transmitted from the read / write module to the control module is reduced, effectively reducing the time required to refresh the electronic paper.
