Taking the terminal as the electronic device shown in fig. 1 as an example, an embodiment of the present invention provides a terminal upgrading method, where the terminal is in communication connection with a cloud, please refer to fig. 2, and fig. 2 is a schematic flow diagram of the terminal upgrading method provided in the embodiment of the present invention. The cloud end can be a self-built cloud end or a public cloud end, and the specific form of the cloud end is not limited by the invention. The terminal upgrading method comprises the following steps:

and S31, acquiring the difference upgrade package of the target firmware.

The difference upgrade package is generated by the cloud according to the current firmware and the target firmware of the terminal. For example, the differential upgrade package may be generated by a Diff algorithm according to an original firmware package (current firmware package) and a target firmware package by a cloud, and the storage space occupied by the differential upgrade package is generally small, such as ten or several Kilobytes (KB), or several tens of KB.

And S32, judging whether the difference upgrade package is matched with the hardware information of the terminal.

The hardware information may include, but is not limited to, a manufacturer of the terminal, a hardware signal, hardware resource information, and the like.

If so, then S33 is performed.

And S33, upgrading the current firmware into the target firmware according to the difference upgrading package.

It can be understood that, according to the terminal upgrading method provided by the invention, by using the difference upgrading package of the original firmware and the target firmware, the terminal only needs to download the difference upgrading package, and does not need to download the whole package of the target firmware, so that the data downloading amount required by firmware upgrading is greatly reduced. On the other hand, by comparing the difference upgrading packet with the hardware information of the terminal, the situation that a certain firmware of the terminal is upgraded to a wrong manufacturer and a wrong hardware model is avoided, and the accuracy of the terminal in firmware upgrading is improved.

In an alternative embodiment, the difference upgrade package may not match the hardware information of the terminal, for example, the terminal corresponding to the target firmware in the difference upgrade package is a "photo wheel 2000" model made by a first manufacturer, and the hardware information of the terminal describes a "wind-fire wheel 2100" model made by a second manufacturer. In order to determine that such a situation occurs, please continue referring to fig. 2, when the difference upgrade package does not match the hardware information of the terminal, the terminal upgrade method may further include:

and S34, sending verification failure information to the cloud.

It should be understood that the mismatch between the hardware information of the difference upgrade package and the hardware information of the terminal is an Error Code (Error Code) of the current round of terminal upgrade process, and when the cloud receives the verification failure information, it is determined that the current round of terminal upgrade fails. For example, the determination process of S32 described above, and thus the subsequent S33 and S34, may be implemented by using a strong check.

In an optional implementation manner, when the terminal downloads the difference upgrade package from the cloud, a situation that the terminal is suddenly powered off or a network failure may occur, and in order to download the difference upgrade package to the terminal, a possible implementation manner is provided on the basis of fig. 2, please refer to fig. 3, and fig. 3 is a schematic flow diagram of another terminal upgrade method provided in an embodiment of the present invention. The above S31 may include:

S311, downloading the difference upgrading package from the cloud, and marking the current downloading point of the difference upgrading package and the current saving point of the terminal.

The current download point is used for confirming the download condition of the difference upgrade package at the cloud end, and the current save point is used for confirming the file save condition of the difference upgrade package at the terminal.

And S312, judging whether the current downloading point is the downloading end point of the terminal.

If yes, S313 is performed.

S313, judging whether the current saving point is the saving end point of the terminal.

If yes, go to S314.

And S314, determining that the difference upgrading packet is successfully acquired.

It should be understood that, by marking the first download point and the first save point of the differential upgrade package, the download condition of the differential upgrade package can be monitored, and thus, the complete acquisition of the differential upgrade package is realized.

In an optional embodiment, after the cloud recording terminal finishes downloading, the terminal may not completely store the difference upgrade package, or a fault occurs when the terminal stores the difference upgrade package, please refer to fig. 3 continuously, and if the current storage point is not the storage end point, the above S31 may further include:

and S315, sending the downloading failure information to the cloud.

It can be understood that the current saving point is not a saving end point, and is also an Error Code (Error Code) of the terminal for performing the firmware upgrading process, and the downloading failure information is sent to the cloud, and the cloud can monitor the firmware upgrading process of the corresponding terminal.

In addition, in an optional embodiment, in the case that the terminal is powered off or has a network failure, if the current download point is not the download end point, please continue to refer to fig. 3, where the above S31 may further include:

and S316, saving the current download point.

And S317, when a continuous downloading request of the user is received, continuously downloading the difference upgrading package from the current downloading point.

It can be understood that, if the terminal is suddenly powered off or has a network fault when the terminal downloads the difference upgrade package from the cloud, the current download point is already stored, and when the terminal recovers power supply or network recovery, the terminal can receive a continuous download request of a user, continuously download the difference upgrade package from the current download point, and then completely download the difference upgrade package to the terminal, and perform a subsequent terminal upgrade process.

In an optional embodiment, when the terminal successfully acquires the complete difference upgrade package, a possible implementation manner is provided for firmware upgrade of the terminal on the basis of fig. 2, please refer to fig. 4, and fig. 4 is a schematic flow diagram of another terminal upgrade method provided in the embodiment of the present invention. The above S33 may include:

s331, acquiring the data offset of the current firmware.

The data offset characterizes a unit of current firmware to be upgraded.

And S332, adding the difference upgrading package to a unit to be upgraded corresponding to the data offset so as to upgrade the current firmware into the target firmware.

For example, the terminal strongly verifies the downloaded difference upgrade package in combination with the hardware information of the terminal itself and information of the manufacturer, the hardware model, the original version, and the like of the current firmware in the difference upgrade package, and only when the difference upgrade package is matched with the hardware information of the terminal itself, the difference upgrade package is used for carrying out difference reduction, so that the firmware upgrade of the terminal is realized. For example, after the verification is passed (i.e. when the difference upgrade package is matched with the hardware information of the terminal), the target firmware is restored through the Patch algorithm, and the difference upgrade is performed to support the power-off protection.

In an optional implementation manner, the difference upgrade package may not match the data offset, for example, when performing differential reduction, a fault occurs, and the like, and a possible implementation manner is provided for firmware upgrade on a terminal on the basis of fig. 4, please refer to fig. 5, where fig. 5 is a schematic flow diagram of another terminal upgrade method provided in an embodiment of the present invention. The above S33 may further include:

And S333, when the difference upgrading package is not matched with the data offset, sending upgrading failure information to the cloud.

It can be understood that the mismatch between the difference upgrade package and the data offset is also an Error Code (Error Code) in the firmware upgrade process of the terminal, and when the cloud receives the upgrade failure information, it determines that the firmware upgrade of the terminal fails.

Next, on the basis of the cloud terminal provided above, in order to implement firmware upgrade of the terminal, taking the cloud terminal in communication connection with the terminal, and taking tag data of manufacturers of target firmware, hardware signals, and the like managed by the cloud terminal as an example, the present invention provides another terminal upgrade method, please refer to fig. 6, where fig. 6 is a schematic flow diagram of another terminal upgrade method provided in an embodiment of the present invention. The terminal upgrading method is applied to a cloud end, and when a firmware upgrading request of a terminal is received, the terminal upgrading method comprises the following steps:

and S42, judging whether the hardware information of the terminal is matched with the difference upgrade package of the target firmware.

If so, then S43 is performed.

And S43, judging whether the current state of the terminal is the state to be upgraded.

If yes, go to S44.

And S44, sending the difference upgrade package to the terminal, so that the terminal upgrades the current firmware of the terminal into the target firmware according to the difference upgrade package.

As can be understood, the cloud receives the device hardware information reported by the terminal in real time: such as manufacturer, hardware model, firmware version, etc., judging whether the difference upgrade package is matched with the hardware information reported by the terminal, and then sending the difference upgrade package to the terminal to realize the firmware upgrade of the terminal.

In an alternative embodiment, in order to obtain the difference upgrade package, please continue to refer to fig. 6, before the foregoing S42, the terminal upgrade method may further include:

and S41, acquiring the difference upgrade package according to the current firmware and the target firmware.

The difference upgrade package includes version information of the current firmware and hardware information of the terminal. For example, the cloud generates a difference upgrade package by using a Siff algorithm through the original firmware package and the target firmware package, and the difference upgrade package is written with a manufacturer, a hardware signal, original version information and the like corresponding to the target firmware. Compared with the FOTA whole package transmission in the prior art, the generated difference upgrade package greatly reduces the transmission data volume and effectively improves the firmware upgrade speed of the terminal by the terminal upgrade method provided by the embodiment of the invention.

In an alternative embodiment, in order to implement the cloud monitoring on the firmware upgrade process of the terminal, please continue to refer to fig. 6, when the hardware information of the terminal does not match the difference upgrade package, the process returns to execute S41.

In an optional embodiment, when the cloud sends the difference upgrade package to the terminal, the terminal may not download successfully, and in order to monitor a firmware upgrade process of the terminal, a possible implementation manner is provided on the basis of fig. 6, please refer to fig. 7, and fig. 7 is a flowchart of another terminal upgrade method provided in an embodiment of the present invention. The above S44 may include:

s441, the difference upgrading packet is sent to the terminal, and the current downloading point of the difference upgrading packet is marked.

The current download point is used for confirming the download condition of the difference upgrade package at the cloud.

And S442, if the current downloading point is the downloading end point of the terminal, determining that the difference upgrading packet is successfully sent.

And S443, if the current download point is not the terminal download end point, receiving the download failure information sent by the terminal.

It can be understood that after the cloud sends the difference upgrade package, the current download point is monitored, so that the firmware upgrade process of the terminal is monitored, whether the difference upgrade package is sent successfully or not is determined, and when the difference upgrade package is sent successfully, the terminal is waited to finish the firmware upgrade process of the current round.
