[0023] If not, the upgrade device will not be upgraded;

[0024] If so, the upgrade device performs step C;

[0025] Upgrade the device upgrade judgment module.

[0026] In some embodiments of this application, the upgrade determination module is further configured as follows:

[0027] When the upgrade strategy meets the preset conditions and user confirmation is not required for downloading, the system waits to receive the URL information sent by the cloud platform.

[0028] In some embodiments of this application, the upgrade determination module is further configured as follows:

[0029] When power is restored after a power outage, the system will report the power-on status to the cloud platform and wait to receive the upgrade policy from the cloud platform.

[0030] In some embodiments of this application, the upgrade determination module is further configured as follows:

[0031] During the download of the upgrade package based on the URL information and during the upgrade process based on the upgrade package, no query or control instructions issued by the cloud platform will be accepted.

[0056] Example 1

[0057] This embodiment provides a remote upgrade system, including a cloud platform, an upgrade device, and a web interface. The web interface is used to generate upgrade policies, the cloud platform is used to receive the upgrade policies, and the upgrade device is used to receive the upgrade policies and perform firmware or software upgrades within the upgrade device.

[0058] Specifically, the upgraded equipment includes:

[0059] The upgrade judgment module is configured to: determine whether the received upgrade strategy meets the preset conditions; if not, report the judgment structure to the cloud platform; if it meets the conditions, upgrade the device to perform the upgrade steps.

[0060] Specifically, the steps for upgrading equipment include:

[0061] Step A: The upgrade device downloads the upgrade package based on the URL information;

[0062] Step B: After the upgrade package is successfully downloaded, it is reported to the cloud platform;

[0063] Step C: The upgrade device upgrades according to the upgrade package;

[0064] Step D: After the upgrade device successfully or fails to upgrade, it reports to the cloud platform.

[0065] The upgrade judgment module upgrades the device. The Uniform Resource Locator (URL) is a concise representation of the location and access method of a resource that can be obtained from the Internet. It is the address of a standard resource on the Internet.

[0066] The upgrade judgment module receives the upgrade policy issued by the cloud platform and determines whether the received upgrade policy meets the preset conditions. If the upgrade policy does not meet the preset conditions, the module reports this judgment result to the cloud platform so that the cloud platform is aware that the upgrade policy does not meet the conditions.

[0067] After receiving the URL information from the cloud platform, the upgrade judgment module reports its current status to the cloud platform before downloading the upgrade package, so that the cloud platform can know that the current status is "before the upgrade package is downloaded".

[0068] The upgrade judgment module downloads the upgrade package based on the URL information and reports the download result (successful or unsuccessful) to the cloud platform so that the cloud platform can know whether the upgrade package was successfully downloaded or failed.

[0069] After the upgrade package is successfully downloaded but before the upgrade is performed, the upgrade judgment module reports the current status to the cloud platform so that the cloud platform can know that the current status is "before upgrade".

[0070] The upgrade judgment module performs the upgrade based on the downloaded upgrade package and reports the upgrade result (upgrade successful or upgrade failed) to the cloud platform so that the cloud platform can know whether the upgrade was successful or failed.

[0071] Therefore, to upgrade the judgment module, the following steps should be performed, see [link to relevant documentation]. Figure 1 As shown.

[0072] Step S11: The upgrade judgment module of the upgrade device receives the upgrade strategy issued by the cloud platform.

[0073] Step S12: Determine whether the received upgrade strategy meets the preset conditions.

[0074] If it is determined that the upgrade strategy does not meet the preset conditions, then step S13 is executed: the judgment result is reported to the cloud platform so that the cloud platform knows that the upgrade strategy does not meet the preset conditions.

[0075] If it is determined that the upgrade strategy meets the preset conditions, then proceed to step S14:

[0076] Step A: The upgrade device downloads the upgrade package based on the URL information;

[0077] Step B: After the upgrade package is successfully downloaded, it is reported to the cloud platform;

[0078] Step C: The upgrade device upgrades according to the upgrade package;

[0079] Step D: After the upgrade device successfully or fails to upgrade, it reports to the cloud platform.

[0080] Therefore, when the upgrade judgment module determines that the upgrade strategy does not meet the preset conditions, it reports the current status to the cloud platform before the upgrade package is downloaded, when the upgrade package is downloaded successfully or fails, before the upgrade, and when the upgrade is successful or fails. This allows the cloud platform to know each node of the entire upgrade process and monitor the entire upgrade process of the upgrade device.

[0081] The upgrade device in this embodiment determines whether the received upgrade strategy meets preset conditions. If it does not meet the preset conditions, the determination result is reported to the cloud platform; if it meets the preset conditions, then...

[0082] The upgrade process for the upgraded device is as follows:

[0083] Step A: The upgrade device downloads the upgrade package based on the URL information;

[0084] Step B: After the upgrade package is successfully downloaded, it is reported to the cloud platform;

[0085] Step C: The upgrade device upgrades according to the upgrade package;

[0086] Step D: After the upgrade device successfully or fails, it reports to the cloud platform. This allows the cloud platform to monitor each node of the upgrade process, solving the technical problem of difficulty in monitoring the upgrade process in existing technologies.

[0087] In some embodiments of this application, in order to enhance user interaction and facilitate user understanding of the entire upgrade process, the upgrade device further includes the following steps before performing the upgrade:

[0088] The first upgrade confirmation module is configured to confirm whether to upgrade after receiving the upgrade strategy.

[0089] If not, the upgrade device will not be upgraded;

[0090] If so, the upgrade device will undergo the following steps.

[0091] To improve the user experience, the upgrade decision module controls the display screen to show a selection box for the user to choose whether to download. If the user chooses to download, the upgrade decision module requests the URL information from the cloud platform. If the user chooses not to download, the upgrade is terminated.

[0092] In some embodiments of this application, the upgrade judgment module is further configured to perform the following operation when the upgrade strategy meets preset conditions and user confirmation is required to download:

[0093] If no confirmation download instruction is received from the user within the first set time period, and no confirmation download instruction is received from the cloud platform, the upgrade will be terminated.

[0094] If a user confirms the download within the first set time period, a request is sent to the cloud platform to send the URL information.

[0095] If a confirmation download instruction is received from the cloud platform within the first set time period, then wait to receive the URL information from the cloud platform.

[0096] In some embodiments of this application, in order to speed up the overall upgrade process of the upgrade device, the upgrade judgment module is further configured to wait to receive URL information sent by the cloud platform when the upgrade strategy meets the preset conditions and the user does not need to confirm whether to download.

[0097] In some embodiments of this application, the upgrade judgment module specifically performs the following steps, see [link to relevant documentation]. Figure 2 As shown.

[0098] Step S21: When the upgrade strategy meets the preset conditions, determine whether user confirmation of download is required.

[0099] If not required, proceed to step S22: wait to receive the URL information sent by the cloud platform.

[0100] If necessary, proceed to step S23.

[0101] Step S23: Control the display screen to show a selection box for the user to choose whether to download.

[0102] Step S24: Determine whether a user confirmation download instruction has been received within the first set time period.

[0103] If so, proceed to step S25: Request the cloud platform to send the URL information.

[0104] If not, proceed to step S26: Exit.

[0105] In some embodiments of this application, in order to enhance user interaction and facilitate user awareness of the entire upgrade process, the upgrade judgment module is further configured to: display a selection box after the upgrade package is successfully downloaded and user confirmation is required for the upgrade, allowing the user to choose whether to upgrade; if a user confirmation instruction is received within a second set time period, the upgrade process is reported to the cloud platform before the upgrade; if no user confirmation instruction is received within the second set time period, the upgrade process is terminated.

[0106] To improve the user experience, the upgrade judgment module controls the display screen to show a selection box for the user to choose whether to upgrade. If the user chooses to upgrade, the upgrade will be reported to the cloud platform before proceeding. If the user chooses not to upgrade, the upgrade will be terminated.

[0107] In some embodiments of this application, the upgrade determination module is further configured to perform the following operation after the upgrade package is successfully downloaded, and when user confirmation is still required:

[0108] If no user confirmation of upgrade is received within the second set time period, and no confirmation of upgrade is received from the cloud platform, the upgrade will be terminated.

[0109] If a user confirms the upgrade or a cloud platform confirms the upgrade is received within the second set time period, the upgrade will be reported to the cloud platform before proceeding.

[0110] In some embodiments of this application, the upgrade judgment module specifically performs the following steps, see [link to relevant documentation]. Figure 3 As shown.

[0111] Between step B and step C, the following is also included:

[0112] The second upgrade confirmation module is configured to confirm whether to upgrade after receiving an upgrade instruction.

[0113] If not, the upgrade device will not be upgraded;

[0114] If so, the upgrade device performs step C.

[0115] In some embodiments of this application, in order to facilitate monitoring of power outages during the upgrade process, the upgrade judgment module is also configured to: when power is restored after a power outage, report the power-on status to the cloud platform and wait to receive the upgrade strategy reissued by the cloud platform.

[0116] When the upgrade device experiences a power outage and then power-on, it reports its current power-on status to the cloud platform so that the cloud platform can be aware of the power-on status. After receiving the power outage and power-on status reported by the upgrade device, the cloud platform reissues the upgrade policy.

[0117] When the upgraded device disconnects from the network and then reconnects, it will report its internet access status to the cloud platform.

[0118] In some embodiments of this application, the upgrade judgment module is further configured as follows:

[0119] During the download of the upgrade package based on the URL information and during the upgrade process based on the successfully downloaded upgrade package, no query or control instructions issued by the cloud platform will be accepted to ensure the smooth progress of the download and upgrade process.

[0120] In some embodiments of this application, the upgrade device may be a central controller, a wired controller, an indoor unit, or an outdoor unit, etc.

[0121] The upgrade device in this embodiment facilitates remote monitoring of the entire upgrade process, has strong dynamic adaptability, and makes it easy to monitor and identify process problems.

[0122] In some embodiments of this application, in order to ensure the accuracy of the upgrade, the upgrade strategy includes the target version number, the upgrade object, the strategy ID, the validity period, etc.

[0123] For example, determining whether the received upgrade strategy meets the preset conditions includes: determining whether the upgrade target version number in the upgrade strategy is consistent with the preset version number. If they are inconsistent, it is determined that the preset conditions are not met and the information is reported to the cloud platform.

[0124] The target version number is the version number to be achieved after this upgrade.

[0125] Upgraded equipment includes central controllers, wired controllers, indoor units, and outdoor units.

[0126] The policy ID is used to identify the policy sequence number, such as policy 01, policy 02, etc.

[0127] The expiration date is a Unix timestamp. This expiration date allows you to obtain a first set duration and a second set duration.

[0128] In some embodiments of this application, the upgrade process of the upgrade device specifically includes the following steps, see below. Figure 4 As shown.

[0129] Step S41: The upgrade device receives the upgrade strategy issued by the cloud platform.

[0130] Step S42: Determine whether the received upgrade strategy meets the preset conditions.

[0131] If it is determined that the upgrade strategy does not meet the preset conditions, then step S43 is executed: the judgment result is reported to the cloud platform.

[0132] If it is determined that the upgrade strategy meets the preset conditions, then proceed to step S44: determine whether user confirmation of download is required.

[0133] If not required, proceed to step S45: wait to receive the URL information sent by the cloud platform.

[0134] If necessary, proceed to step S46.

[0135] Step S46: Display a selection box for the user to choose whether to download.

[0136] Step S47: Determine whether a user confirmation download instruction has been received within the first set time period.

[0137] If not, proceed to step S48: Exit.

[0138] If so, proceed to step S49: Request the cloud platform to send the URL information.

[0139] Step S50: The cloud platform sends out URL information.

[0140] Step S51: After receiving the URL information issued by the cloud platform, report the current status to the cloud platform before downloading the upgrade package.

[0141] Step S52: Download the upgrade package according to the URL information and report the download result (successful or failed) to the cloud platform.

[0142] Step S53: After the upgrade package is successfully downloaded, a selection box is displayed for the user to choose whether to upgrade.

[0143] Step S54: Determine whether a user confirmation of upgrade has been received within the second set time period.

[0144] If not, proceed to step S55: Exit.

[0145] If so, proceed to step S56: Report to the cloud platform before upgrading.

[0146] Step S57: Perform the upgrade according to the upgrade package and report the upgrade result (upgrade success or failure) to the cloud platform.

[0147] In some embodiments of this application, the upgrade process of the upgrade device specifically includes the following steps, see [link to relevant documentation]. Figure 5 As shown.

[0148] Step S61: The upgrade device receives the upgrade strategy issued by the cloud platform.

[0149] Step S62: Determine whether the received upgrade strategy meets the preset conditions.

[0150] If it is determined that the upgrade strategy does not meet the preset conditions, then step S63 is executed: the judgment result is reported to the cloud platform.

[0151] If it is determined that the upgrade strategy meets the preset conditions, then proceed to step S64: determine whether user confirmation of download is required.

[0152] If not required, proceed to step S65: wait to receive the URL information sent by the cloud platform.

[0153] If necessary, proceed to step S66.

[0154] Step S66: Display a selection box for the user to choose whether to download.

[0155] Step S67: Determine whether a user confirmation download instruction has been received within the first set time period.

[0156] If not, proceed to step S68: Exit.

[0157] If so, proceed to step S69: Request the cloud platform to send the URL information.

[0158] Step S70: URL information issued by the cloud platform.

[0159] Step S71: After receiving the URL information issued by the cloud platform, report the current status to the cloud platform before downloading the upgrade package.

[0160] Step S72: Download the upgrade package according to the URL information, and report the download result (whether the upgrade package was successfully downloaded or not) to the cloud platform.

[0161] Step S73: Report to the cloud platform before upgrading.

[0162] Step S74: Perform the upgrade according to the upgrade package and report the upgrade result (upgrade success or failure) to the cloud platform.

[0163] Upgraded devices with color touchscreens can perform more complex interactions, making the remote upgrade process more complicated, but also more detailed and user-friendly. The download and upgrade process is broken down into two steps (requiring two user confirmations: download confirmation and upgrade confirmation), executed as steps S41 to S57.

[0164] For the upgrade devices in the segment display series, the download and upgrade are combined into one step (i.e., user confirmation is required once), namely, steps S61 to S74.

[0165] In existing technologies, remote upgrades of multi-split air conditioning controllers, wired controllers, and other upgrade equipment often vary due to limitations in product form and characteristics. However, by utilizing the aforementioned remote upgrade method, upgrade equipment can adapt to diverse product needs, effectively monitor the upgrade process, and achieve better interaction with users.

[0166] To simplify the detailed upgrade process, the functions are abstracted into code names, and the functions corresponding to the codes are shown in the table below.

[0167] Table 1

[0168]

[0169]

[0170] Below, we will take a wired controller as an example, where both downloading and upgrading require user confirmation. Figure 6 The upgrade process will be explained in detail.

[0171]

Note 1

[0172]

Note 2

[0173]

Note 3

[0174] [Note 4] After the device receives OTA downlink command 1, 2, or 3, it means that OTA has started, and the device stops all reporting except for OTA. It will resume after OTA ends.

[0175] like Figure 6 As shown, the specific process is as follows:

[0176] (11) The cloud platform issues an upgrade request, which includes an upgrade strategy and a flag indicating whether user confirmation is required. Specifically, the upgrade request includes the content from points 132 and 134. Figure 6 The first item is issued.

[0177] (12) Determine whether the received upgrade strategy meets the preset conditions.

[0178] If the conditions are not met, the wired controller will report all points to the cloud platform via OTA, including point 131 (=1), point 132 (content sent by the cloud platform), and the default values ​​for other points. Figure 6 Report 1 in the middle.

[0179] If the conditions are met, then determine whether user confirmation is required.

[0180] If user confirmation is not required, execute directly (13).

[0181] If user confirmation is required, the message will be displayed on the wired controller's LCD screen, awaiting the user's confirmation before downloading.

[0182] If the user does not click "Confirm" within the time limit and does not receive a confirmation download instruction from the cloud platform, the process will end.

[0183] If the user receives a confirmation download command from the cloud platform (i.e.) Figure 6 If the waiting period is 2), then execute (13).

[0184] If the user clicks to confirm the download, the wired controller reports all OTA (Over-The-Air) settings to the cloud platform, including setting point 128 (=1), point 132 (content sent by the cloud platform), and the default values ​​for other points. Figure 6 Report 2 in the middle. Then execute (13).

[0185] (13) The cloud platform issues an upgrade request, including for points 132 and 133. Figure 6 The third item is issued.

[0186] If user confirmation is required, the wired controller reports all points to the cloud platform via OTA, including point 129 (=1), point 132 (content sent by the cloud platform), and default values ​​for other points. Figure 6 Report 3 in the middle. Then execute (14).

[0187] If no user confirmation is required (i.e., silent upgrade), the wired controller reports all OTA data points to the cloud platform, including point 129 (=2), point 132 (content sent by the cloud platform), and the default values ​​for other points. Figure 6 Report 9 in the middle. Then execute (14).

[0188] (14) Download the upgrade package according to the URL information. During the download, communication with the cloud platform is disconnected.

[0189] If the download fails, the wired controller reports all OTA data points to the cloud platform, including point 129 (=4), point 132 (content sent by the cloud platform), and the default values ​​for other points. Figure 6 Report 5 and Report 11.

[0190] If the download is successful, the wired controller reports all OTA data points to the cloud platform, including point 129 (=3), point 132 (content sent by the cloud platform), and the default values ​​for other points. Figure 6 Report 4 and report 10.

[0191] (15) After successful download, the message is pushed to the LCD screen of the wired controller, and the user is asked to click to confirm the upgrade.

[0192] If the user does not click "Confirm" within the time limit and does not receive a confirmation upgrade instruction from the cloud platform, the process will end.

[0193] If the user clicks "Confirm," or receives a confirmation upgrade command from the cloud platform (i.e.) Figure 6 If the OTA (Over-The-Air) notification (4) is sent, the wired controller will report all OTA points to the cloud platform, including point 130 (=1), point 132 (the content sent by the cloud platform), and the default values ​​for other points. Figure 6 The report is number 6.

[0194] (16) Upgrade according to the upgrade package.

[0195] If the upgrade fails, the wired controller reports all points to the cloud platform via OTA, including point 130 (=3), point 132 (content sent by the cloud platform), and the default values ​​for other points. Figure 6 The report is number 8.

[0196] If the upgrade is successful, the wired controller will report all points to the cloud platform via OTA, including point 130 (=2), point 132 (content sent by the cloud platform), and the default values ​​for other points. Figure 6 The report is number 7.

[0197] Below, we will take the wired controller as an example, where the upgrade download only requires one user confirmation, and combine it with... Figure 7 The upgrade process will be explained in detail.

[0201] [Note 4] After the device receives OTA downlink command 1, 2, or 3, it means that OTA has started, and the device stops all reporting except for OTA. It will resume after OTA ends.

[0202] like Figure 7 As shown, the specific process is as follows:

[0222] Example 2

[0223] Based on the design of the upgrade device in Embodiment 1, Embodiment 2 proposes a remote upgrade device system including the upgrade device.

[0224] Upgraded equipment can be a central controller, wired controller, indoor unit, or outdoor unit.

[0225] Upgrade the equipment, including the upgrade judgment module and the function control module, see [link / reference]. Figure 8 As shown.

[0226] The upgrade judgment module is used to control the entire upgrade process of the upgrade device.

[0227] The function control module is used to control the upgraded equipment to achieve the corresponding functions.

[0228] For example, when upgrading equipment to a central controller / wired controller, its functional control module is used to enable the central controller / wired controller to control the indoor and outdoor units.

[0229] When the equipment is upgraded to an indoor / outdoor unit, its function control module is used to control the cooling / heating process.

[0230] The remote upgrade system of this embodiment, by designing the upgrade device, facilitates cloud platform monitoring of each node of the upgrade process, thus solving the technical problem of difficulty in monitoring the upgrade process of existing upgrade devices.

[0231] Example 3

[0232] This embodiment proposes a remote upgrade system, including a cloud platform, upgrade equipment, a web interface, and a mobile terminal, etc. See [link / reference]. Figure 10 As shown.

[0233] The web-based application is used to publish upgrade strategies.

[0234] The cloud platform is used to receive upgrade policies published on the web and to send the information reported by the upgraded devices to the web and mobile terminals.

[0235] The upgrade device is used to receive upgrade policies issued by the cloud platform and report status information to the cloud platform.

[0236] The mobile terminal is used to communicate with the cloud platform, receive messages pushed by the cloud platform, and send user instructions to the cloud platform.

[0237] When user authorization is required for downloading or upgrading, confirmation can be made on the mobile terminal or on the device itself (upgrading device).

[0238] In some embodiments of this application, to facilitate user operation, when the user needs to confirm whether to download / upgrade, the upgrade device or mobile terminal displays a selection box for the user to choose whether to download / upgrade, and the user's selection is uploaded to the cloud platform.

[0239] In some embodiments of this application, to further verify whether the upgrade was successful, the upgrade device reports its version number to the cloud platform after the upgrade is completed. The cloud platform determines whether the version number reported by the upgrade device is consistent with the target version number in the upgrade strategy. If they are consistent, the upgrade strategy is pushed to the mobile terminal APP for display. If they are inconsistent, the upgrade strategy is not displayed in the details of the mobile terminal APP.

[0240] During the remote upgrade system upgrade process, the upgrade policy is published on the web client and sent to the cloud platform. The cloud platform simultaneously pushes the upgrade policy to both the mobile terminal and the upgrade device. Users can confirm whether to download / upgrade on their mobile terminal or the upgrade device. After the upgrade is completed, the upgrade device reports the upgrade results to the cloud platform. The cloud platform compares the upgrade results and pushes the results to both the mobile terminal and the web client.

[0241] The remote upgrade system in this embodiment utilizes a cloud platform to monitor each node of the upgrade process of the upgrade device, thus solving the technical problem that the upgrade process of the upgrade device is not easy to monitor in the prior art.

[0242] In the description of the above embodiments, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.

[0243] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
