[0045] Figure 2 This is a flow chart of OTA function upgrade in an embodiment of the present invention;

[0046] Figure 3 This is a block diagram of the internal structure principle of the terminal device provided in an embodiment of the present invention. DETAILED DESCRIPTION

[0047] The following is a clear and complete description of the technical solution of the present invention in combination with the embodiments and the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] According to research, a project involves multiple manufacturers' equipment, and the system versions of multiple manufacturers' equipment must be upgraded to the same version to ensure that multiple manufacturers' equipment can work together in the same project. For example, a smart home project involves smart home appliances (manufacturer equipment) from various manufacturers. Each manufacturer will set up an OTA function (download function) in the smart home appliances. After the project is implemented, if inconsistent upgrades are required for each smart home appliance, it will cause problems in the collaborative work of each smart home appliance in the smart home project. The existing device upgrade method is that each manufacturer's equipment is connected to its own terminal, and each manufacturer's terminal directly upgrades each manufacturer's equipment, which will lead to inconsistent upgrades of each manufacturer's equipment.

[0049] In order to solve the above technical problems, the present invention provides a device upgrade method, system, terminal device and storage medium, which solves the problem that the existing device upgrade will cause inconsistent upgrades of devices from different manufacturers. In specific implementation, the client first sends unified version upgrade information to the cloud platform, and then the cloud platform sends the version upgrade information to the manufacturer's device. The manufacturer's device parses the version upgrade information to obtain the download address, and then the manufacturer's device sends the download address to the manufacturer's terminal. The manufacturer terminal then downloads the upgrade package according to the download address, and finally sends the upgrade package to each manufacturer's device. Since the upgrade of each manufacturer's device is controlled by the client, it can ensure that the devices of each manufacturer are upgraded consistently.

[0050] For example, the smart home project involves a TV (manufacturer equipment) and an audio device (manufacturer equipment). The TV and the audio device are both equipped with a download function OTA. These two devices come from two different manufacturers, Manufacturer A and Manufacturer B. If Manufacturer A upgrades the download function OTA of the TV and Manufacturer B upgrades the download function OTA of the audio device, it may result in the two devices being upgraded to different versions in the end, resulting in the TV and the audio device being unable to download video and audio synchronously after the upgrade, resulting in the TV and the audio device being unable to play audio and video works collaboratively after the upgrade. In order to solve the above problem, the present embodiment uniformly sends version upgrade information to the cloud platform by the client, and the cloud platform then sends the version upgrade information to the TV and the audio device respectively. The two respectively parse the same version upgrade information to obtain the same download address, and then send the same download address to the manufacturer terminal. The manufacturer terminal downloads the same upgrade package and feeds it back to the TV and the audio device respectively. Finally, the TV and the audio device can upgrade their respective download functions in a consistent manner according to the same upgrade package.

[0051] Exemplary Methods

[0052] like Figure 1 As shown in , the device upgrade method specifically includes the following steps:

[0053] S100, the cloud platform receives version upgrade information sent by the client.

[0054] This embodiment is for upgrading the OTA function in home appliances. The user needs to upgrade the OTA function in the home appliance to a certain version, and sends the version information to the cloud platform. The cloud platform performs subsequent processing according to the upgrade information until the manufacturer terminal downloads the upgrade package and feeds it back to each manufacturer's equipment (home appliances produced by each manufacturer).

[0055] In one embodiment, before receiving the version upgrade information sent by the client, the cloud platform needs to first send the unified communication protocol to each client and the manufacturer's terminal, so that a unified communication protocol is established between the client, the manufacturer's terminal, and the manufacturer's equipment, thereby ensuring that the three can communicate normally. After the unified communication protocol is established, the manufacturer's terminal will send its existing version of the OTA function to the cloud platform, and the cloud platform will forward the existing version to the client, so that the user can choose to upgrade the OTA function to the specified version according to the existing version. For example, there are first-generation versions, second-generation versions, and third-generation versions on the manufacturer's terminal. The manufacturer's terminal sends the information that the OTA function has these three versions to the cloud platform, and the cloud platform forwards it to the client. The user can view the three versions through the client, and then choose to upgrade the OTA function to the second-generation version of these three versions.

[0056] In one embodiment, step S100 includes the following steps S101, S102, S103, S104, and S105:

[0057] S101, the cloud platform pushes a unified communication protocol to the client.

[0058] S102, the cloud platform receives a communication response, where the communication response is a response made by the client according to the unified communication protocol.

[0059] The cloud platform first pushes a unified communication protocol to the client, such as the common language used for communication. When the cloud platform receives the communication response sent by the client, it indicates that the client agrees to establish communication between the two. At this point, the communication protocol is established between the two, and subsequent normal communication can be carried out.

[0060] S103, after the cloud platform receives the communication response, the cloud platform receives the upgrade instruction sent by the client.

[0061] S104, after receiving the upgrade instruction, the cloud platform pushes the unified communication protocol to each manufacturer's equipment.

[0062] S105, after the cloud platform pushes the unified communication protocol, it receives the version upgrade information sent by the receiving client.

[0063] This embodiment first establishes the communication protocol between the cloud platform and the client, then receives the OTA function upgrade instruction sent by the client, then establishes the communication protocol between the cloud platform and the manufacturer's equipment, and finally the cloud platform receives the version upgrade information sent by the client. If the cloud platform has established the communication protocol with the manufacturer's equipment before receiving the upgrade instruction, then when the instruction is received, the communication protocol between the two may be interrupted, and continuing to receive the version upgrade information sent by the client and then sending the version upgrade information to the manufacturer's equipment without knowing the interruption may result in erroneous transmission. This embodiment establishes the communication protocol only after receiving the upgrade instruction, which can avoid the above problems.

[0064] S200, the cloud platform sends the version upgrade information to the devices of each manufacturer.

[0065] The devices of various manufacturers in this embodiment are located in the same project, and the OTA functions of the devices of various manufacturers are uniformly upgraded with the help of the cloud platform and the manufacturer terminal, so that the OTA functions of the devices of various manufacturers after the upgrade can work collaboratively in the same project.

[0066] S300: The manufacturer terminal receives the download addresses sent by the devices of each manufacturer.

[0067] In this embodiment, the manufacturer's equipment first parses the version upgrade information sent by the cloud platform to parse out the version download address, rather than the manufacturer's terminal parsing it. This embodiment can reduce the computing power of the manufacturer's terminal, thereby enabling the manufacturer's terminal to save computing power and download subsequent upgrade packages more quickly.

[0068] S400, the manufacturer terminal downloads the upgrade package according to each of the download addresses.

[0069] In one embodiment, each manufacturer's device sends verification information to the manufacturer's terminal at the same time as sending the download address. This allows the manufacturer's terminal to have the authority to manage the OTA function upgrades of each manufacturer's device, rather than allowing each manufacturer's device to freely decide whether to upgrade, which would result in inconsistent upgrades of each manufacturer's device and prevent the devices of each manufacturer from working together in the same project. The detailed process of step S400: verify each manufacturer's device according to the device authentication information; download the upgrade package for the download address sent by the manufacturer's device that has passed the verification.

[0070] S500: The manufacturer terminal sends the upgrade package to each of the manufacturer's devices.

[0071] Step S500 includes the following processes: detecting the current version information of the space download software inside each manufacturer's device; sending the upgrade package to the target device, which is the manufacturer's device whose current version information is lower than the set version.

[0072] In this embodiment, the cloud platform detects whether the devices of each manufacturer have upgraded the OTA function to the set version before the client issues an upgrade instruction. If a manufacturer's device has upgraded the OTA function to the set version, the manufacturer's terminal will not send the upgrade package to the manufacturer's device, thereby avoiding waste of resources.

[0073] In one embodiment, the overall process of uniformly upgrading the OTA functions in the devices of various manufacturers is as follows: Figure 2 As shown:

[0074] (I) Design a unified push communication protocol between the cloud platform and manufacturer equipment.

[0075] (ii) Manufacturers' equipment is uniformly connected to the push protocol to receive upgrade push information from the cloud platform.

[0076] (3) The cloud platform connects to the OTA backend of each product manufacturer's terminal to obtain the firmware version information and firmware download address of each product. The manufacturer's terminal still has independent management rights over the product firmware, while the cloud platform has the right to select the version and whether to upgrade.

[0077] (IV) The cloud platform configures the versions that can be used by the products in the project to ensure that the project and product firmware versions correspond one to one.

[0078] (V) The cloud platform can perform overall version detection and update of the product firmware (OTA) version under a specified project, and can also perform version detection and update of one or more specified products.

[0079] (VI) The device management client (the client that manages the devices of each manufacturer) can also perform version detection and update on the devices of the specified manufacturer.

[0080] (VII) The cloud platform and device management client can push the specified version update information and download address to the device end (manufacturer terminal) through the cloud platform.

[0081] (VIII) After receiving the pushed information, the device will check the version information. If the upgrade conditions are met and it is confirmed that the device is authorized by the manufacturer, it will download and upgrade through the upgrade package address.

[0082] The following is an example to illustrate the upgrading method of the present invention:

[0083] In the application scenario of project A, it is found that product a needs to be upgraded to fix a problem. The manufacturer repairs the problem of product a in the application scenario of project A and submits it to the manufacturer's own OTA background (manufacturer terminal) for management. The administrator (client) performs version detection on product a under project A from the cloud platform background, obtains the version information of product a from the manufacturer's OTA system, and confirms and configures the version. The version information of product a in project B has not changed. After confirming the version information, push it to all product a under the project for firmware upgrade with one click.

[0084] In summary, the present invention firstly sends unified version upgrade information (i.e., which version each manufacturer's equipment needs to be upgraded to) from the user's client to the cloud platform, and then the cloud platform sends the version upgrade information to each manufacturer's equipment. Each manufacturer's equipment parses the version upgrade information to obtain a download address, and then sends the download address to the manufacturer's terminal. The manufacturer's terminal downloads the corresponding unified upgrade package based on the unified download address, and finally sends the upgrade package to each manufacturer's equipment, and each manufacturer's equipment is uniformly upgraded through the upgrade package. Since the present invention relies on the client to send unified version upgrade information, which reaches the manufacturer's terminal through the cloud platform and the manufacturer's equipment, it is ultimately ensured that the upgrade package sent by the manufacturer's terminal to the manufacturer's equipment is unified, thereby ensuring that each manufacturer's equipment can be consistently upgraded.

[0085] In addition, the present invention is crucial for the unified management of manufacturers' equipment upgrades, which can improve operation and maintenance efficiency and reduce after-sales costs, and will be introduced into cloud platforms and ecological products to achieve rapid integration of product OTA upgrades.
