Description

Technical Field

[0001] The present invention relates to the field of intelligent device control technology, and in particular, to a device upgrade method based on a Web serial port function, a computer device applying the device upgrade method based on a Web serial port function, and a computer-readable storage medium applying the device upgrade method based on a Web serial port function. Background Art

[0002] Currently, most interactions between clients and hardware devices are based on the traditional client / server architecture, which focuses more on security and platform independence. This is more suitable for scenarios that require cross-platform access and data security, but there are also some difficulties. For example, the interaction between clients and hardware devices is highly dependent on network connections. When the network is unstable, there will be high latency, which may even affect the real-time data transmission and network transmission performance. In addition, for large amounts of data transmission, network bandwidth may become a bottleneck.

[0003] Requesting access to serial devices through the Web Serial API provided by the browser is more suitable for scenarios of real-time data processing and large-scale data transmission. The Web Serial API allows web applications to communicate directly with serial devices without the need for users to download and install additional drivers or software. This allows direct two-way communication between web applications and serial devices, just like in local applications, enabling convenient and intelligent control of traditional home appliances.

[0004] When upgrading the system of some existing devices, users are required to download and install additional upgrade drivers or upgrade software, which will cause a certain burden on the device. Therefore, in order to improve the convenience of device system upgrades, it is possible to consider applying the WebSerial API to the system upgrade of smart devices. Summary of the invention

[0005] The first object of the present invention is to provide a device upgrade method based on a Web serial port function that improves the convenience of device system upgrade.

[0006] A second object of the present invention is to provide a computer device that improves the convenience of equipment system upgrades.

[0007] A third object of the present invention is to provide a computer-readable storage medium that improves the convenience of device system upgrades.

[0008] In order to achieve the above-mentioned first purpose, the device upgrade method based on Web serial port function provided by the present invention includes: opening the control platform webpage in the browser, and pairing and connecting the serial port corresponding to the device to be upgraded on the control platform webpage; opening the serial port corresponding to the device to be upgraded, so that the browser can communicate with the device to be upgraded; when the upgrade instruction is obtained, obtaining the upgrade file corresponding to the device to be upgraded, and performing the upgrade operation on the device to be upgraded.

[0009] It can be seen from the above scheme that the device upgrade method based on the Web serial port function of the present invention realizes the communication between the browser and the device to be upgraded by utilizing the Web serial port function, and when the upgrade instruction is obtained, the upgrade file corresponding to the device to be upgraded is obtained, and the upgrade operation is performed on the device to be upgraded, thereby realizing the system upgrade of the device to be upgraded by using the web page, without downloading and installing additional upgrade drivers or upgrade software, thereby improving the convenience of device upgrade.

[0010] In a further scheme, the step of pairing and connecting the serial port corresponding to the device to be upgraded on the control platform web page includes: displaying a list of serial port devices connected to the upgrade control device; when an instruction to authorize the connection to the serial port corresponding to the device to be upgraded is obtained, pairing and connecting the serial port corresponding to the device to be upgraded.

[0011] It can be seen that the control platform webpage pairs and connects the serial port corresponding to the device to be upgraded, and displays a list of serial port devices connected to the upgraded control device, which is convenient for users to make connection selections.

[0012] In a further solution, the step of opening the serial port corresponding to the device to be upgraded includes: setting configuration parameters of the serial port corresponding to the device to be upgraded.

[0013] It can be seen that when opening the serial port corresponding to the device to be upgraded, the configuration parameters of the serial port corresponding to the device to be upgraded are set so that the serial port can perform protocol and parameter verification at the data transmission level.

[0014] In a further scheme, the step of setting the configuration parameters of the serial port corresponding to the device to be upgraded includes: generating test configuration parameters of the serial port corresponding to the device to be upgraded, and using the test configuration parameters to change the parameter settings of the serial port corresponding to the device to be upgraded; sending preset test instructions to the device to be upgraded and obtaining response data; if the preset response data is obtained, determining that the test configuration parameters are the configuration parameters of the serial port corresponding to the device to be upgraded.

[0015] It can be seen that when setting the configuration parameters of the serial port corresponding to the device to be upgraded, by automatically generating the test configuration parameters of the serial port corresponding to the device to be upgraded and detecting whether the test configuration parameters are consistent with the current serial port, the work efficiency is significantly improved, the possibility of manual configuration errors is reduced, and the debugging and maintenance of the device becomes more convenient and quick.

[0016] In a further solution, the step of opening the serial port corresponding to the device to be upgraded includes: if the serial port corresponding to the device to be upgraded fails to be opened, after clearing the cached data of the browser, pairing and connecting the serial port corresponding to the device to be upgraded and opening the serial port.

[0017] It can be seen that when opening the serial port corresponding to the device to be upgraded, if the serial port opening fails, the browser cache data needs to be cleared to release the cached data that has not been released by the data read and write stream generated after the user previously opened the Web serial port, ensuring that the current serial port is in an idle state.

[0018] In a further scheme, the step of obtaining the upgrade file corresponding to the device to be upgraded includes: if the upgrade file has been pre-stored in the upgrade control device, uploading the upgrade file stored on the upgrade control device to the control platform web page; if the upgrade file is stored in a remote server, the control platform web page downloads the upgrade file from the remote server.

[0019] It can be seen that when obtaining the upgrade file corresponding to the device to be upgraded, the upgrade file can be obtained by obtaining the local file or downloading the file from the server, which can help expand the acquisition channels of the upgrade file and improve the convenience of device upgrade.

[0020] In a further solution, after the step of performing an upgrade operation on the device to be upgraded, the method further includes: closing the serial port corresponding to the device to be upgraded and canceling the connection authorization.

[0021] It can be seen from this that after upgrading the device to be upgraded, close the Web serial port and cancel the connection authorization to avoid excessive browser resource consumption and cause freezing problems.

[0022] In a further solution, after opening the control platform webpage in the browser, it also includes: confirming whether the current browser supports the Web serial port function, and if not, sending a prompt message to change the browser.

[0023] It can be seen that by confirming whether the current browser supports the Web serial port function, the user can be informed and change the browser when the current browser does not support the Web serial port function.

[0024] In order to achieve the second objective of the present invention, the present invention provides a computer device including a processor and a memory, wherein the memory stores a computer program, and when the computer program is executed by the processor, the steps of the above-mentioned device upgrade method based on the Web serial port function are implemented.

[0025] In order to achieve the third objective of the present invention, the present invention provides a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a controller, the steps of the above-mentioned device upgrade method based on the Web serial port function are implemented. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Device upgrade method embodiment based on Web serial port function:

[0032] The device upgrade method based on the Web serial port function of the present invention is a computer program applied to the upgrade control device, which is used to perform system upgrade on the device to be upgraded. In this embodiment, the upgrade control device includes one of a mobile phone, a computer, and a central control screen, and the device to be upgraded includes household appliances such as air conditioners, washing machines, and refrigerators. The upgrade control device communicates with the device to be upgraded through a serial port.

[0033] like Figure 1 As shown, in this embodiment, when the device upgrade method based on the Web serial port function is working, step S1 is first executed to open the control platform webpage in the browser. When the device needs to be upgraded, the user can open the visual control platform webpage in the form of a URL link on a mobile phone, computer or other smart device to control the smart device to perform the upgrade operation.

[0034] After opening the control platform webpage, step S2 is executed to confirm whether the current browser supports the Web serial port function. Whether the current browser supports the Web serial port function can be confirmed by using known technical means, for example, Web Serial API example webpages, which can be opened in the current browser to check whether the serial port function can be used normally. If the webpage can successfully detect the serial port device and communicate, the browser supports the function. Otherwise, if an error message appears or the function cannot work normally, the browser does not support the function.

[0035] If it is confirmed that the current browser does not support the Web serial port function, step S3 is executed to send a browser change prompt message. By sending the browser change prompt message, the user can be reminded to change the browser.

[0036] If it is confirmed that the current browser supports the Web serial port function, step S4 is executed to pair the serial port corresponding to the device to be upgraded on the control platform webpage. If the current browser supports the Web serial port function, a further serial port pairing operation can be performed to enable the browser to communicate with the device to be upgraded.

[0037] In this embodiment, see Figure 2 When pairing the serial port corresponding to the device to be upgraded on the control platform webpage, first execute step S41 to display a list of serial port devices connected to the upgraded control device. In order to facilitate the user to make a connection selection, it is necessary to display a list of all serial port devices connected to the upgraded control device, for example, Figure 3 The serial port device list is shown.

[0038] After the list of serial port devices connected to the upgrade control device is displayed, step S42 is executed to determine whether an instruction to authorize the serial port corresponding to the device to be upgraded is obtained. After the list of serial port devices connected to the upgrade control device is displayed, the user can select the device to be upgraded according to the serial port device list for authorized connection. The instruction to authorize the serial port corresponding to the device to be upgraded can be obtained through the virtual button in the serial port device list.

[0039] If an instruction to authorize the serial port corresponding to the device to be upgraded is obtained, step S42 is continued to be executed for continuous detection. When an instruction to authorize the serial port corresponding to the device to be upgraded is obtained, step S43 is executed to pair the serial port corresponding to the device to be upgraded. The pairing connection of the device is a technology well known to those skilled in the art and will not be described in detail here. Of course, if the device to be upgraded is already in a pairing state, the pairing connection operation may not be performed.

[0040] After pairing and connecting the serial port corresponding to the device to be upgraded, step S5 is executed to open the serial port corresponding to the device to be upgraded so that the browser can communicate with the device to be upgraded. After pairing and connecting the serial port corresponding to the device to be upgraded, the serial port corresponding to the device to be upgraded needs to be opened to realize communication between the browser and the device to be upgraded.

[0041] In this embodiment, the step of opening the serial port corresponding to the device to be upgraded includes: setting the configuration parameters of the serial port corresponding to the device to be upgraded. When opening the serial port corresponding to the device to be upgraded, the configuration parameters of the serial port corresponding to the device to be upgraded are set so that the serial port can perform protocol and parameter verification at the data transmission level. The configuration parameters of the serial port include parameters such as baud rate, data bit, stop bit, check bit, flow control, etc.

[0042] The configuration parameters of the serial port corresponding to the device to be upgraded can be set by manual input or by automatic detection input.

[0043] In an optional embodiment, see Figure 4 When setting the configuration parameters of the serial port corresponding to the device to be upgraded, first execute step S51 to generate the test configuration parameters of the serial port corresponding to the device to be upgraded, and use the test configuration parameters to change the parameter settings of the serial port corresponding to the device to be upgraded. By automatically generating the test configuration parameters of the serial port corresponding to the device to be upgraded, different configuration parameters can be set to test which configuration parameter meets the requirements of the current serial port.

[0044] After the parameter settings of the serial port corresponding to the device to be upgraded are changed using the test configuration parameters, step S52 is executed to send a preset test instruction to the device to be upgraded and obtain response data. The preset test instruction can be preset according to experimental data.

[0045] After the response data is obtained, step S53 is executed to determine whether the preset response data is obtained. The preset response data is set according to the preset test instruction. By comparing the response data with the preset response data, it can be determined whether the preset response data is obtained.

[0046] If the preset response data is not obtained, then continue to execute step S51 to generate the next set of test configuration parameters. If the preset response data is obtained, execute step S54 to determine that the test configuration parameters are the configuration parameters of the serial port corresponding to the device to be upgraded. When setting the configuration parameters of the serial port corresponding to the device to be upgraded, by automatically generating the test configuration parameters of the serial port corresponding to the device to be upgraded, and detecting whether the test configuration parameters are consistent with the current serial port, the work efficiency is significantly improved, the possibility of manual configuration errors is reduced, and the debugging and maintenance of the device becomes more convenient and quick.

[0047] In this embodiment, the step of opening the serial port corresponding to the device to be upgraded also includes: if the serial port corresponding to the device to be upgraded fails to be opened, after clearing the cached data of the browser, pairing and connecting the serial port corresponding to the device to be upgraded and opening the serial port.

[0048] There are three reasons why the unreleased cached data in the data read and write streams may cause the serial port to fail to open: (1) Resource occupation: When opening a serial port connection through the Web Serial API, the browser will allocate corresponding system resources to manage the connection. If these resources (such as cached data) are not properly processed and released before closing the connection, these resources may still be occupied. In this case, when trying to reopen the same serial port, the system may think that the serial port is still occupied, resulting in a failure to open. (2) Incomplete I / O operations: If there are uncompleted read and write operations before closing the serial port connection, these operations may block the connection closing process, which may cause the browser or operating system to think that the serial port is still in use, thereby blocking new connection requests. (3) Inconsistent serial port status: If the serial port is abnormally closed in the middle of data transmission (such as a sudden power outage or disconnection), it may cause the serial port to be in an uncertain state. This state may require a specific reset command or reinitialization to return to normal.

[0049] To clear the cached data in the browser, you can refresh the page. When the page is refreshed, all resources and scripts related to the page will be reloaded, and the serial port that has been opened will be automatically closed. To clear the cached data in the browser, you can also clear it by closing the page. When you close the tab or window of the page containing the open serial port, the serial port will also be automatically closed. To clear the cached data in the browser, you can also clear it by navigating away from the current page. If you navigate from the current page to another page (even in the same tab), the serial port will be closed.

[0050] In addition, to avoid the situation where the browser cache data is not cleared, the following measures can be taken when ending communication: automatically release resources. After the communication between the web page and the hardware is completed, make sure to call the appropriate method to close the data read and write streams. For example, in the communication between the web page and the hardware, if the serial port has finished reading the data, make sure to close the data read stream when the data is no longer needed. For the data write stream, make sure to close the data write stream after all the data has been sent to release resources. Finally, after the data read and write streams are closed correctly, the serial port connection needs to be closed. These operations can ensure that all related resources are released and the serial port is in an idle state.

[0051] After opening the serial port corresponding to the device to be upgraded, step S6 is executed to determine whether an upgrade instruction is obtained. The upgrade instruction can be obtained by controlling the system upgrade virtual button displayed on the platform webpage.

[0052] If the upgrade instruction is not obtained, continue to execute step S6 for continuous detection. When the upgrade instruction is obtained, execute step S7 to obtain the upgrade file corresponding to the device to be upgraded and perform the upgrade operation on the device to be upgraded. When the upgrade instruction is obtained, the upgrade operation needs to be performed. The system upgrade is completed by obtaining the upgrade file corresponding to the device to be upgraded and transmitting data with the device to be upgraded through the web serial port.

[0053] In this embodiment, the step of obtaining the upgrade file corresponding to the device to be upgraded includes: if the upgrade file has been pre-stored in the upgrade control device, the upgrade file stored in the upgrade control device is uploaded to the control platform webpage; if the upgrade file is stored in a remote server, the control platform webpage downloads the upgrade file from the remote server. If the air-conditioning system upgrade file has been pre-stored on the local computer, the user can choose to click the "Select File" virtual button to upload the local upgrade file to the webpage. If the air-conditioning system upgrade file exists on the remote server, the webpage will first download the upgrade file from the remote server. When uploading the upgrade file on the webpage, the system can automatically detect whether the firmware is compatible with the target device to avoid device failure caused by firmware mismatch. The webpage can also provide a safer file transfer and storage environment. During the upload process, the upgrade firmware file can be checked, such as verifying the integrity and authenticity of the file to prevent the implantation of malicious software. At the same time, the webpage also processes the upgrade firmware file, such as subpackaging and managing data transmission, to complete the upgrade of the smart device. During the upgrade process, the communication log between the browser and the device to be upgraded and the system upgrade log of the device to be upgraded can be displayed to the webpage for the user to view the specific situation of the upgrade of the device to be upgraded.

[0054] After the upgrade operation is completed for the device to be upgraded, step S8 is executed to close the serial port corresponding to the device to be upgraded and cancel the connection authorization. After the upgrade operation is completed for the device to be upgraded, the Web serial port is closed and the connection authorization is canceled to avoid the problem of freezing caused by excessive browser resource consumption.

[0055] From the above, it can be seen that the device upgrade method based on the Web serial port function of the present invention realizes the communication between the browser and the device to be upgraded by utilizing the Web serial port function, and when the upgrade instruction is obtained, the upgrade file corresponding to the device to be upgraded is obtained, and the upgrade operation is performed on the device to be upgraded, thereby realizing the system upgrade of the device to be upgraded by using the web page, without downloading and installing additional upgrade drivers or upgrade software, thereby improving the convenience of device upgrade.
