[ first embodiment ] A method for manufacturing a semiconductor device
Referring to fig. 1, a first embodiment of the present invention provides a display screen replacement method, as shown in fig. 1, for example, including steps S11 through S14.
Step S11: displaying the local address code and the initial program version number;
step S12: responding to a human-computer interaction instruction to modify the local address code to obtain a target address code, and replacing the local address code with the target address code to display;
step S13: determining a target folder from a plurality of media folders according to the target address code, wherein the plurality of media folders correspond to a plurality of display screens one to one; and
step S14: and acquiring and storing at least one target medium in the target folder according to the local information recording file, and replacing the initial program version number with the current program version number corresponding to the at least one target medium for displaying so as to finish display screen replacement.
In step S11, the local address code mentioned above is, for example, a row-column two-dimensional coordinate, which is an initial position code of the replacement display screen, i.e., the new display screen, in the complete picture displayed by splicing the plurality of display screens, or a one-dimensional information code, which is an initial serial number of the replacement display screen in the plurality of display screens. The mentioned initial program version number is the local program version number of the replacement display screen, and the corresponding program version number changes every time the program is updated.
In step S12, the mentioned human-computer interaction command is, for example, a command generated by a user inputting a shortcut key on a keyboard. The mentioned target address code is an initial position code, namely a row-column two-dimensional coordinate, of the replaced display screen in a complete picture displayed by splicing a plurality of display screens, or a serial number of the replaced display screen in the plurality of display screens. Step S11 and step S12 may be understood as displaying the local address code and the initial program version number when the display screen is powered on, then modifying the local address code into the target address code in response to the human-computer interaction instruction, and displaying the target address code in place of the local address code, so that the user can check the address code and the program version number to determine whether the modification is successful, which is more intuitive and improves the user experience. In step S13, the mentioned plurality of media folders are located in an external mobile device, for example, a usb disk, plug and play. The mentioned media folders correspond to the display screens one by one, each media folder name includes, for example, an address code of the corresponding display screen, and each media folder includes at least one media and an information recording file in which media information corresponding to the at least one media is recorded. The media mentioned are for example video or pictures or the like material. The information recording file mentioned is, for example, an md5.json file. The media information mentioned includes, for example, media name, media size, and media feature code. The mentioned multiple display screens are, for example, multiple handheld display screens, that is, handheld display screens, which are different from the conventional fixed LED display screens, and the display screen related to this embodiment can be held by a user and can be moved to change positions at will. The plurality of display screens may form a complete picture when playing a program, each display screen being adapted to display a portion of the complete picture. The local address code mentioned above may also be a serial number of the performer, that is, during an actual performance, when each performer holds the display screen to perform a performance, each performer corresponds to one serial number, and when the performer holds the display screen to move, the serial number corresponding to the performer is not changed.
Further, step S13 includes, for example: and matching the target address code with the address code included by each media folder name, and taking the successfully matched media folder as the target folder. Because each media folder name comprises the address code of the corresponding display screen, one display screen corresponds to one media folder, the situation that the display screen downloads media corresponding to other display screens is avoided, and the error rate of media downloading is reduced.
The local information recording file mentioned in step S14 is, for example, an md5.json file, which records local media information corresponding to local media, and the mentioned local media information includes, for example, a local media name, a local media size, and a local media feature code.
Further, step S14 includes, for example: acquiring the information recording file in the target folder; matching the information recording file with the local information recording file to determine the at least one target medium in the at least one medium to be downloaded; downloading the at least one target media from the target folder. The target media can be quickly determined by matching the information recording files, and the media downloading speed is improved.
Further, the mentioned matching the information recording file with the local information recording file to determine the at least one target medium in the at least one medium to be downloaded includes: and matching the media feature codes corresponding to the media in the information recording file with the local media feature codes corresponding to each local media in the local information recording file in sequence, and taking the media corresponding to the media feature codes which are not matched successfully as target media. The media feature code is an automatically generated unique media identifier and cannot be tampered. The media feature code is the unique identifier of the media and cannot be tampered, so that whether the media exist can be accurately judged by matching the media feature code, and repeated downloading of the media is avoided.
Further, after downloading the at least one target medium from the target folder, for example, the method further includes a step of verifying the target medium, specifically, generating a target medium feature code according to the media content of the target medium, matching the target medium feature code of the target medium with the corresponding medium feature code in the information recording file, and when the target medium feature code is the same as the medium feature code corresponding to the information recording file, the target medium passes verification. Therefore, the security and the accuracy of the media can be ensured, and the situation that the media is illegally tampered by people and is unknown can be avoided.
Further, step S11 includes, for example: when media content is played, the local address code and the initial program version number are superposed on the media content for display. It can be understood that if the address code is set, the display screen plays the media content, then the address code and the program version number will be prior to the media content display process, for example, the address code and the program version number are displayed in transparent superposition on the media content or directly overlaid on the media content, so as to realize the display of the address code and the program version number, and avoid the situation that the address code and the program version number are covered by the media content.
Further, after step S14, the display screen replacement method provided in the embodiment of the present invention further includes, for example: and automatically playing media content corresponding to a first priority media in the at least one target media, wherein the first priority media are the media with the highest priority in a preset playing sequence of the at least one target media. Therefore, the success of updating the program of the replacement display screen is clearly shown, and the picture can be displayed instead of the replaced display screen.
Furthermore, the size of each media in the media folder is the same as the resolution of the corresponding display screen, so that various defects that the display screen needs to intercept the media according to the loaded position information of the display screen after receiving the media are avoided, transmission flow is reduced, and waste of flow is avoided.
For better understanding of the present embodiment, a specific implementation of the present embodiment is described below with reference to fig. 2 to 3.
The display screen replacement method disclosed in this embodiment is implemented, for example, in a display screen system including a plurality of display screens, where a plurality of LED display screens play programs to form a complete picture, and when a problem occurs in a certain display screen in the display screen system and needs to be replaced for maintenance, a standby display screen replaces a maintenance display screen to perform picture display, that is, the display screen replacement method disclosed in this embodiment can be implemented on the standby display screen to quickly complete display screen replacement to replace the maintenance display screen to perform picture display.
As shown in fig. 2, the display screen system includes, for example, a main control server, a Lora base station, a Lora module, a control system, an LED display screen body, and a media server, and optionally further includes a status monitoring server. Fig. 2 only illustrates one LED display screen as an example to illustrate the connection relationship of the LED display screen in the display screen system, and in an actual application scenario, a plurality of LED display screens, for example, hundreds of LED display screens, may be involved.
Specifically, the control system and the Lora module form a control card, and the control card and the LED display screen form an LED display screen, wherein the Lora module can be externally connected with an ARM processor in the control system, namely, the Lora module and the control system are in a split structure; or the Lora module and the control system are arranged on the same circuit board, namely, the Lora module and the control system are of an integral structure.
The media server is mainly used for storing media corresponding to a plurality of display screens, for example, the media server includes a plurality of media folders corresponding to the display screens one by one, and each media folder includes at least one media and an information recording file for recording media information corresponding to the at least one media. The LED display screen and the media server are in wireless network communication through a mobile network or in wired network communication through a network cable, for example.
The state monitoring server is mainly used for monitoring the downloading progress of each LED display screen and controlling the downloading process, and the control system is connected with the state monitoring server through an MQTT/TCP protocol. In addition, the state monitoring server can also issue control instructions to a plurality of display screens. The state monitoring server can be realized through a BS framework or a CS framework, when the configuration parameters of the control system are correct, the state monitoring server is automatically connected, then SN numbers and local address codes are uploaded, the state monitoring server establishes a state monitoring list after receiving the information, monitors information such as the on-line condition, the downloading completion condition and the playing sequence number of the current playing media of the LED display screen, and can also control the on-off screens of a plurality of display screens in batch and adjust the states such as brightness through the state monitoring server.
The master control server and the Lora base station are matched to complete wireless issuing of control instructions to the plurality of display screens. For example, the master server and the Lora base station are connected through a USB-to-RS 485 connection line or a USB-to-RS 232 connection line, for example. It should be noted that the Lora base station according to this embodiment has a frequency hopping function in addition to being used for protocol conversion, that is, the frequency information of a plurality of display screens can be changed.
The master server, the media server, and the status monitoring server are, for example, the same host computer, such as a personal computer, a hand-held device, a portable device, a tablet device, a multi-processor system, a microprocessor-based system, an editable consumer electronics device, a network PC, a minicomputer, a mainframe computer, a distributed computing environment that includes any of the above systems or devices, and the like. Of course, the master control server, the media server and the state monitoring server may be in different upper computers, for example, and when the number of the plurality of display screens is too large, a plurality of media servers are required.
The playing of the plurality of LED display screens forms a complete picture, and is realized by solidifying the display content in advance in the control card and synchronously playing. The program material is produced in advance as follows:
firstly, making an integral material, namely a material required by a plurality of display screens to display a complete picture, and then cutting the complete picture material according to the number of the display screen bodies, for example: the size of the LED display screen is 96 × 96, the complete picture material is cut according to 96 × 96 pixels corresponding to each LED display screen body to obtain a plurality of materials, namely media, corresponding to the LED display screens respectively, then each media is named according to the format of an address code _ video playing serial number, for example, 0201_01.mov, the former number represents the address code of the LED display screen corresponding to the media, the address code represents a row-column two-dimensional coordinate or a one-dimensional information code, and the next 2-digit number represents the media playing serial number. Then, as shown in fig. 3, a media folder is created according to the address code of each LED display screen, for example, 2 rows and 1 columns are 0201, for example, address codes of 9999 LED display screen bodies are supported, and the media corresponding to each LED display screen is placed in the corresponding media folder. A plurality of media folders corresponding to the plurality of LED display screens are stored in a media server and/or a U disk, for example. Each media folder includes, for example, media and md5.json files, each media folder does not limit the number of media, and the md5.json files store media information corresponding to the media, including media name, media size, and media feature code, i.e., MD5 code, where MD5 code is a unique identifier of the media, which can prevent repeated downloading of the media. Each media size is the same as the resolution of the corresponding display screen, so that the waste of flow can be prevented, and the media size can also realize the breakpoint continuous transmission function.
When the standby display screen is to replace the replaced display screen, the address code of the standby display screen needs to be reset quickly, and the corresponding program updating needs to be completed according to the reset address code.
Specifically, the ARM processor in the control system of the LED display screen is connected to the USB interface, and can be operated by using common external mobile devices such as a USB keyboard in an actual application field, which is described below by taking the USB keyboard as an example.
The LED display screen is electrified to automatically display the local address code and the initial program version number, the local address code and the initial program version number are digital code characters for example, the initial program version number is displayed below the local address code for example, and the display size of the initial program version number is smaller than that of the local address code.
And connecting the USB keyboard to a USB interface of the LED display screen, inputting a shortcut key by a user, such as 'F5 + target address code + enter command', thereby generating a man-machine interaction instruction, and modifying the local address code into the target address code by the LED display screen according to the man-machine interaction instruction, and replacing the local address code for displaying. The user can see the address code and program version number currently displayed on the display screen to determine if modification is required and if the modification is successful.
After the address code modification of the LED display screen is completed, the USB disk storing a plurality of media folders is connected to the USB interface, so that the LED display screen downloads the media in the corresponding media folder from the USB disk according to the target address code, because the naming rule of the media folder is well agreed in advance, as mentioned above, different LED display screens download the target media in the media folder corresponding to the address code stored by the LED display screen, specifically, the md5.json file in the media folder includes the media name, the media size, and the media feature code corresponding to all the media in the media folder, the LED display screen downloads the md5.json file in the media folder first, compares the md5.json file with the local md5.json file, for example, compares the media feature codes in the two files, and when a certain media feature code in the md5.json is not matched with all the media feature codes in the local md5.json, the media corresponding to the media feature code is the target media, the target media is downloaded, and then downloaded from the media folder. When the download is successfully verified, the LED display screen displays the current program version number to replace the initial program version number.
In addition, when the LED display screen plays the media content when the display screen replacement operation is performed, the address code and the program version number are displayed in preference to the media content, for example, the address code and the program version number are transparently overlapped or directly overlaid on the media content for display.
In addition, after the program updating of the LED display screen is completed, the media content with the media playing sequence number of 1 can be automatically played to indicate that the current program is updated successfully.
In summary, the display screen replacement method provided by the embodiment of the present invention modifies the local address code to obtain the target address code and displays the target address code by displaying the local address code and the initial program version number in response to the human-computer interaction instruction, determines the target folder from the plurality of media folders to obtain the target media and display the current program version number, and completes the display screen replacement, so that the LED display screen with a problem in the new LED display screen replacement can be quickly displayed, the display screen replacement efficiency is improved, the operation is simple, the manpower is saved, the address code and the program version number are displayed, the user can conveniently check whether the modification is successful, and the user experience is improved; the media folder name comprises the address code of the corresponding display screen, so that the target folder can be quickly identified, and the condition of downloading media corresponding to other display screens is avoided; the target media is downloaded through the information recording file, so that the media can be prevented from being downloaded again, and power-off continuous transmission is realized; the size of target media is the same with the resolution ratio of display screen, prevents that the flow is extravagant, reduces transmission flow, need not the intercepting and can directly show, avoids the display screen to carry out the multiple drawback that the intercepting produced to the media.
