Description

Technical Field

[0001] The present application relates to the technical field of software upgrade, and in particular to a microcontroller unit upgrade method, apparatus, intelligent device and storage medium. Background Art

[0002] The upgrade process of traditional household appliances generally allows the microcontroller unit (MCU) of smart devices to download upgrade packages from the server through communication with the Internet of Things module to achieve remote upgrade. However, complex smart devices usually contain multiple MCU processors to perform work together. When multiple MCUs have upgrade requests, not all MCUs can directly establish a communication link with the Internet of Things module to download the upgrade package from the server to perform the upgrade. Therefore, some need to establish a communication link between the mother MCU among multiple MCUs and the Internet of Things module to download the upgrade package from the server.

[0003] In the prior art, when upgrading a plurality of microcontrol units consisting of a mother microcontrol unit and a plurality of sub-microcontrol units, the mother microcontrol unit will obtain the upgrade packages of all the microcontrol units to be upgraded from the server, back them up in the mother microcontrol unit, and then transmit them one by one to the microcontrol units to be upgraded. In this way, when the upgrade package is damaged due to external environmental influences, it is necessary to download the upgrade package from the server again through the mother microcontrol unit for upgrading. When this is applied in a multi-layer communication network, if the upgrade package is damaged, it is necessary to repeatedly download and cache the upgrade package from the server. Such repeated downloading of the upgrade package will result in low upgrade efficiency of the microcontrol units in the smart device. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0069] The embodiments of the present application provide a method, device, intelligent device and storage medium (i.e., computer-readable storage medium) for upgrading a microcontroller unit. Among them, the method for upgrading a microcontroller unit can be applied to a microcontroller unit upgrading device, which can be specifically integrated in an intelligent device, which can be connected to a server or terminal for communication, and the server can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery networks (Content Delivery Network, CDN), and big data and artificial intelligence platforms, but is not limited to this. The server and the terminal can be directly or indirectly connected via wired or wireless communication, which is not limited to this in the present application. The terminal can be a mobile phone, a computer, a home appliance, or a wearable device.

[0070] It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0071] In this embodiment, the description will be made from the perspective of a smart device. Figure 1 , Figure 1 : is a flowchart of a micro control unit upgrade method provided in an embodiment of the present application. The micro control unit upgrade method may include:

[0072] S101, sending attribute information of multiple micro control units on a smart device to a server, where the multiple micro control units include a main micro control unit and at least one level of sub-micro control units;

[0073] The smart device may be a household appliance, a computer, a mobile phone, a wearable device, etc. The multiple microcontroller units (MCU) may include a mother microcontroller unit and multiple levels of sub-microcontroller units corresponding to the mother microcontroller unit. The mother microcontroller unit may be connected to a server, and at least one level of sub-microcontroller unit may be connected to the server through the mother microcontroller unit. Figure 4 , Figure 4It is a schematic diagram of multiple micro control units, wherein the multiple micro control units include a primary mother micro control unit, a secondary sub micro control unit, a tertiary sub micro control unit, and a quaternary sub micro control unit, the micro control unit is connected to a communication module, the communication module may be a WiFi module, the mother micro control unit may be connected to a server through the WiFi module, and thus perform data transmission with the server. The attribute information may include software versions, partition information, hardware versions of multiple micro control units, and device information of smart devices, and the partition information may be identification information corresponding to the functional modules corresponding to the micro control units. The attribute information may be stored locally in the smart device.

[0074] For example, the smart device obtains the attribute information of multiple micro control units locally, reports the attribute information of at least one first-level sub-micro control unit to the mother micro control unit, and sends the attribute information of multiple micro control units in the smart device to the server through the micro control unit, so that the server can determine the target micro control unit that needs to be upgraded based on the attribute information.

[0075] Optionally, the mother micro control unit of the smart device can send the attribute information of multiple micro control units to the server through the communication module. For example, the smart device sends the attribute information of multiple micro control units to the communication module through the mother micro control unit, and the communication module sends the attribute information of the multiple micro control units to the server.

[0076] S102, receiving a target upgrade notification of a target micro control unit returned by the server based on the attribute information of the multiple micro control units, wherein the target micro control unit is determined according to the attribute information of the multiple micro control units and the reference attribute information in the server.

[0077] Among them, the target micro-control unit refers to the micro-control unit that needs to be upgraded among multiple micro-control units in the smart device, and the target micro-control unit can be a parent micro-control unit or a child micro-control unit. The attribute information corresponding to the target upgrade package matches the attribute information of the target micro-control unit. The target upgrade notification may include candidate attribute information corresponding to the target micro-control unit determined in the server, and the target upgrade notification can be used to notify the target micro-control unit that there is a target upgrade package corresponding to the latest version of the software corresponding to the target micro-control unit in the server, so that the smart device obtains the target upgrade package from the server, and the candidate attribute information may match or not match the attribute information of the target micro-control unit.

[0078] It should be noted that if the candidate attribute information matches the attribute information of the target micro-control unit, it can be indicated that the target upgrade notification sent by the server has the same partition information and hardware information as the target micro-control unit in the smart device, and only the software version is different, that is, it can be determined that the micro-control unit to which the target upgrade notification is sent is the correct target micro-control unit to be upgraded, or that the target upgrade notification is not damaged. If the candidate attribute information does not match the attribute information of the target micro-control unit, it can be indicated that the target upgrade notification sent by the server has different partition information or hardware information from the target micro-control unit in the smart device, and the software versions are the same or different, that is, it can be determined that the micro-control unit to which the target upgrade notification is sent is not the correct target micro-control unit to be upgraded, or that the target upgrade notification has been damaged.

[0079] For example, the server generates a target upgrade notification corresponding to the target micro control unit based on the attribute information of the multiple micro control units. The smart device receives the target upgrade notification of the target micro control unit returned by the server based on the attribute information of the multiple micro control units through the mother micro control unit.

[0080] S103, sending a target upgrade notification to the target micro control unit through the mother micro control unit.

[0081] Optionally, sending the target upgrade notification to the target micro control unit through the mother micro control unit includes:

[0082] S1. Obtaining the partition information of the target micro control unit according to the target upgrade notification;

[0083] The partition information may be identification information corresponding to a functional module of the target micro control unit.

[0084] It can be understood that the target upgrade notification includes the candidate software version, candidate partition information and candidate hardware version of the target micro control unit determined by the server, and the partition information of the target micro control unit is determined according to the candidate partition information.

[0085] For example, the smart device obtains identification information corresponding to the candidate partition information, and obtains target partition information corresponding to the identification information.

[0086] S2. Determine the target position of the target micro control unit according to the partition information.

[0087] The target position may refer to the position of the functional module corresponding to the target micro-control unit in the multiple micro-control units of the intelligent device. For example, the target position may be the third sub-micro-control unit in the three-level sub-micro-control unit. Figure 4 , which is where the functional module 7 is located.

[0088] S3. Send a target upgrade notification to the target micro control unit according to the target position.

[0089] For example, if the target position is the position of functional module 7, that is, the third-level sub-micro control unit corresponding to functional module 7 is the target micro control unit, the target upgrade notification is sent to the third-level sub-micro control unit corresponding to functional module 7 to notify the third-level sub-micro control unit that it needs to be upgraded.

[0090] Sending a target upgrade notification to the target microcontroller unit according to the target position includes:

[0091] (1) Determine the communication link between the target MCU and the mother MCU according to the target location.

[0092] The communication link is a transmission route formed by at least one level of sub-micro control units from the position corresponding to the mother micro control unit to the target position.

[0093] For example, if the target position is the location of functional module 7, the communication link between the mother micro control unit and the three-level sub-micro control unit corresponding to functional module 7 includes the first-level mother micro control unit, the second-level sub-micro control unit corresponding to functional module 4, and the third-level sub-micro control unit corresponding to functional module 7.

[0094] (2) Sending the target upgrade notification to the target micro control unit via the communication link.

[0095] For example, the smart device can send the target upgrade notification to the secondary sub-micro control unit corresponding to the functional module 4 through the primary micro control unit, and then send the target upgrade notification to the tertiary sub-micro control unit corresponding to the functional module 7 through the secondary sub-micro control unit corresponding to the functional module 4.

[0096] Sending a target upgrade notification to a target micro control unit via a communication link includes:

[0097] Acquire at least one level of sub-micro control unit in the communication link; send a target upgrade notification to at least one level of sub-micro control unit; perform protocol conversion on the target upgrade notification by at least one level of sub-micro control unit to obtain a target upgrade notification of a target protocol, where the target protocol is a protocol corresponding to the target micro control unit; send the target upgrade notification of the target protocol to the target micro control unit.

[0098] It is understandable that since the manufacturer or hardware of each microcontroller unit in the smart device may be different, the communication protocol of each microcontroller unit may be different. Therefore, in order to enable data communication between microcontroller units at different levels, the smart device needs to first obtain the protocols of each microcontroller unit corresponding to the communication link of the target upgrade notification to be received during the process of transmitting to the target microcontroller unit when transmitting the target upgrade notification to microcontroller units at different levels. For each level of microcontroller unit transmitted, the protocol of the target upgrade notification is converted into the protocol corresponding to the microcontroller unit receiving the target upgrade notification, until the target upgrade notification is sent to the target microcontroller unit, the protocol of the target upgrade notification is converted into the target protocol corresponding to the target microcontroller unit, the target upgrade notification of the target protocol is obtained, and the target upgrade notification of the target protocol is sent to the target microcontroller unit.

[0099] For example, if the communication link includes a first-level mother micro-control unit, a second-level sub-micro-control unit corresponding to functional module 4, and a third-level sub-micro-control unit corresponding to functional module 7, then the intelligent device can obtain the first protocol corresponding to the first-level mother micro-control unit, the second protocol corresponding to the second-level sub-micro-control unit corresponding to functional module 4, and the target protocol corresponding to the third-level sub-micro-control unit corresponding to functional module 7, perform protocol conversion on the target upgrade notification of the first protocol in the mother micro-control unit to obtain the target upgrade notification of the second protocol, send the target upgrade notification of the second protocol from the mother micro-control unit to the second-level sub-micro-control unit corresponding to functional module 4, then perform protocol conversion on the target upgrade notification of the second protocol again to obtain the target upgrade notification of the target protocol, and send the target upgrade notification of the target protocol to the target micro-control unit, that is, the third-level sub-micro-control unit corresponding to functional module 7.

[0100] Corresponding, refer to Figure 6 , Figure 6 The present invention is a schematic diagram of protocol conversion of a target upgrade package, wherein the target microcontroller unit may be a microcontroller unit corresponding to an external machine drive board. Thus, after the communication module receives the target upgrade package sent by the server, the target upgrade package is subjected to protocol conversion to obtain a first protocol target upgrade package corresponding to the display board, and the first protocol target upgrade package is transmitted to the microcontroller unit corresponding to the display board. The target upgrade package is then subjected to protocol conversion again to obtain a second protocol target upgrade package corresponding to the internal machine drive board, and the second protocol target upgrade package is transmitted to the microcontroller unit corresponding to the internal machine drive board. The second protocol target upgrade package is then subjected to protocol conversion again to obtain a target upgrade package of the target protocol, and the target upgrade package of the target protocol is transmitted to the target microcontroller unit, i.e., the microcontroller unit corresponding to the external machine drive board, to upgrade the software of the microcontroller unit corresponding to the external machine drive board.

[0101] S104: When the candidate attribute information in the target upgrade notification matches the attribute information of the target micro control unit, the qualified information of the target upgrade notification is sent to the parent micro control unit.

[0102] The target microcontroller unit's attribute information includes the target software version, target partition information and target hardware version, and the target upgrade notification includes the target microcontroller unit's candidate attribute information, which includes the candidate software version, candidate partition information and candidate hardware version.

[0103] Optionally, when the candidate attribute information in the target upgrade notification matches the attribute information of the target micro control unit, before sending the qualified information of the target upgrade notification to the parent micro control unit, the following may be included:

[0104] Obtain the candidate software version, candidate partition information and candidate hardware version in the candidate attribute information, and obtain the target software version, target partition information and target hardware version of the target microcontroller unit; if the candidate software version is different from the target software, and the candidate partition information is the same as the target partition information, and the candidate hardware version is the same as the target hardware version, then determine that the candidate attribute information matches the attribute information of the target microcontroller unit.

[0105] For example, if the candidate software version in the candidate attribute information is "xx software 5", the candidate partition information is "function module 7", and the candidate hardware version is "xx hardware 3", and the target software version of the target microcontroller unit is "xx software 4.6", the target partition information is "function module 7", and the target hardware version is "xx hardware 3", then the candidate software version is different from the target software, and the candidate partition information is the same as the target partition information, and the candidate hardware version is the same as the target hardware version, then it is determined that the candidate attribute information matches the attribute information of the target microcontroller unit, that is, the target upgrade notification can be determined to be a qualified target upgrade notification, qualified information of the target upgrade notification can be generated, and the qualified information can be sent to the mother microcontroller unit.

[0106] S105 , the mother micro control unit obtains a target upgrade package from the server based on the received qualified information, and sends the target upgrade package to the target micro control unit to upgrade the target micro control unit.

[0107] Obtain the target upgrade package from the server, which can include:

[0108] S1, sending a target upgrade package acquisition request of a target micro control unit to a server;

[0109] The target upgrade package acquisition request may include attribute information of the target micro control unit, so that the server sends the target upgrade package matching the attribute information to the smart device.

[0110] S2. Receive the target upgrade package returned by the server based on the target upgrade package acquisition request.

[0111] For example, the server may determine the target upgrade package according to the target upgrade package acquisition request received from the smart device, and send the target upgrade package to the smart device. The smart device receives the target upgrade package.

[0112] In this embodiment, the smart device can send attribute information of multiple microcontroller units on the smart device to the server through the communication module, and the multiple microcontroller units include a mother microcontroller unit and at least one level of child microcontroller units; receive a target upgrade notification of the target microcontroller unit returned by the server based on the attribute information of the multiple microcontroller units, and the target microcontroller unit is determined based on the attribute information of the multiple microcontroller units and the reference attribute information in the server; send the target upgrade notification to the target microcontroller unit through the mother microcontroller unit; when the candidate attribute information in the target upgrade notification matches the attribute information of the target microcontroller unit, send qualified information of the target upgrade notification to the mother microcontroller unit; obtain the target upgrade package from the server based on the received qualified information through the mother microcontroller unit, and send the target upgrade package to the target microcontroller unit to upgrade the target microcontroller unit. In this way, when the smart device upgrades the target microcontroller unit that needs to be upgraded, it can first obtain the target upgrade notification corresponding to the target microcontroller unit, and after determining that the target upgrade notification is qualified, it can receive the target upgrade package of the target microcontroller unit. In this way, the mother microcontroller unit does not need to back up the target upgrade package of the target microcontroller unit, and only when there is no abnormality in the upgrade package, that is, when the target upgrade notification is qualified, will it obtain the target upgrade package to upgrade the target microcontroller unit, avoiding the problem of storage redundancy caused by the smart device repeatedly downloading unqualified upgrade packages, thereby improving the upgrade efficiency of the microcontroller unit.

[0113] Based on the above embodiments, refer to Figure 2 , Figure 2 is another flow chart of the micro control unit upgrade method provided in an embodiment of the present application, wherein the micro control unit upgrade method is applied to a server, comprising:

[0114] S201. Receive attribute information of multiple micro control units sent by a smart device.

[0115] The server may be a cloud server. The plurality of microcontroller units (MCU) may include a mother microcontroller unit and a plurality of levels of sub-microcontroller units corresponding to the mother microcontroller unit. The mother microcontroller unit may be connected to the server, and at least one level of sub-microcontroller units may be connected to the server through the mother microcontroller unit.
