Description

Wearable device upgrading method, wearable device and storage medium

Technical Field

The application relates to the technical field of wearable equipment, in particular to a FOTA upgrading method, wearable equipment and a storage medium.

Background

With the popularization of intelligent terminals, wearable electronic devices such as intelligent watches, intelligent bracelets and the like have great market prospects. In order to provide better functionality, security, etc. to users, wearable device manufacturers need to often push out operating system upgrade packages to optimize the performance of the wearable device, provide new functionality, or address known potential safety hazards, etc.

Air Firmware upgrade (Firmware Over-The-Air, FOTA for short) mobile terminal, namely through cloud upgrade technology, is a device with networking function: for example, a mobile phone, a tablet computer, a portable media player, a mobile internet device, a wearable device and the like provide firmware upgrade services, a user uses a network to obtain an intelligent terminal system upgrade package in an on-demand and easily-extensible mode, and cloud upgrade is performed through a FOTA, so that system repair and optimization are completed.

In the process that a user uses wearable equipment (for example, a wrist machine is a mobile phone model in the form of a smart watch, the appearance is more similar to that of the smart watch, but the front surface of the mobile phone model is almost completely covered by a long and thin flexible material screen, and the characteristics of the wearable equipment and the mobile phone are integrated), as the use time is longer and longer, the storage space of the wearable equipment is smaller and smaller, and currently, when the FOTA is adopted, the system partition (system partition for short) is required to ensure that the residual space exceeds a certain threshold (for example, 200 Mb), otherwise, the upgrade is not allowed.

1) Because the memory of the wrist machine is smaller than that of the mobile phone, the residual space of the system partition is often smaller than the threshold value, and the upgrade is failed, so that the upgrade can be continuously completed only after the user manually cleans the storage space, the operation is troublesome, and the user experience is poor. Even though the storage space of the wrist machine is larger and larger along with the development of the technology, on one hand, the volume of the wrist machine is smaller, the memory space of the wrist machine is still smaller than that of a mobile phone, on the other hand, the scale of a system upgrade package is also larger and larger, and in addition, the storage space of the wrist machine sold earlier is smaller than that of the wrist machine of the current model, when a manufacturer pushes the upgrade package, the wrist machine of the early version in the support period needs to be considered, so that the shortage of the storage space of the wrist machine is a problem to be solved when the manufacturer provides the system upgrade.

2) Moreover, some mobile phones with poor configuration or older mobile phones are generally poorer in storage space than the current mainstream mobile phones, and the mobile phones are likely to suffer from system partition space deficiency to cause system upgrade failure.

Example 1

Please refer to fig. 6, 7 and 8. The invention provides a method for upgrading wearable equipment, which comprises the following steps:

s101, the wearable device detects an upgrade package;

s102, the wearable device downloads an upgrade package, and the wearable device checks the size of the residual space of the system partition;

s103, if the residual space of the system partition is larger than or equal to a preset value A, the wearable device executes a normal upgrading process; if the residual space of the system partition is smaller than the preset value A, the wearable device acquires the size of the residual space and executes the following steps;

s104, decompressing the upgrade package to a cache partition by the wearable device, and decomposing the upgrade package into a plurality of decomposition sub-packages by the wearable device;

s105, if half of the residual space of the system partition is larger than or equal to the positive integer times of the space of the decomposition sub-package with the largest occupied space, the wearable device dynamically processes the update_script upgrading script according to the number of the sub-packages;

s106, the wearable device upgrades each decomposition sub-packet respectively, and immediately clears the decomposition sub-packet after the completion of the upgrade of each decomposition sub-packet.

In the above scheme: step S101, the wearable device periodically inquires whether an upgrade package adapting to the current wearable device exists at a server side, and if the upgrade package adapting to the current wearable device is checked, the server sends a message to the wearable device. Step S102, the wearable device downloads an upgrade package from a server side, and can access the Internet through WiFi or wireless cellular networks and the like, and downloads the upgrade package from the server side; of course, to accelerate the download, the wearable device may also download the upgrade package from an adjacent mirror server; after the upgrade package is downloaded, the integrity and the like of the upgrade package also need to be verified, a private key is arranged on the wearable device, a public key is arranged on the server, and whether the upgrade package is legal or not can be confirmed by verifying the digital signature of the upgrade package. In step S103, a sufficient memory space margin needs to be ensured during the system upgrade, otherwise, the upgrade may fail due to insufficient memory space, and it needs to be determined that the remaining space size of the system partition is higher than a preset value a (as shown in step S103A), where the preset value a is specified by the operating system or set by a user, for example: preset value a=200m; if the remaining space of the system partition is large enough, the normal upgrade process (see step S103B) may be directly entered, and if the remaining space of the system partition is insufficient, the upgrade method of the present invention is needed for processing. In step S104, the upgrade package is decomposed for several times in the cache partition, and a plurality of decomposition packages with reduced volumes are obtained from one upgrade package (compressed package file), so that the residual space of the system partition required in the upgrade process is reduced. The decomposition operation in step S104 may be performed once or several times, but is not limited to infinite decomposition, and the minimum unit of subcontracting is to obtain a patch file with an independent upgrade function, and the patch file may be used in the upgrade process. After the packetizing operation is finished, it is further required to determine that the volume of the largest space occupied by the current decomposed sub-packet is less than half of the system partition, if the assumption is true, step S106 is executed to perform packetizing upgrade, and if the assumption is false, the user is prompted to perform a space cleaning operation.

That is, the upgrade method of the present invention can reduce the possibility of upgrade failure caused by insufficient storage space, but if the operation of decomposing the upgrade package is performed, the unrewritable decomposed sub-package still cannot fail due to the file volume exceeding the preset value a (e.g. 200M), and at this time, the user needs to be prompted to manually perform space cleaning.

Preferably, the wearable device comprises a wrist machine. The wearable device can operate an Android (English: android) system.

Preferably, in step S105, the positive integer multiple is 1 time, 2 times, 3 times, … …, or the like.

When the wearable device downloads the upgrade package from the server or the mirror server, the downloading time can be determined according to the size of the upgrade package, for example: and when the file volume of the upgrade package is larger than a preset value C (for example, the preset value C=100deg.M), the upgrade package is downloaded by adopting a WiFi network, and when the file volume is smaller than or equal to the preset value C, the upgrade package is downloaded by adopting a WiFi or wireless cellular network. During the download process, if a network change occurs, for example: downloading is suspended when switching from the WiFi network to the wireless cellular network (e.g., 2G network, 3G network, 4G network, 5G network, etc.), and the download task continues when switching from the wireless cellular network to the WiFi network. The preset value C can be specified by an operating system or can be manually set by a user for specification or modification.

Preferably, the upgrade package is a FOTA upgrade package. The server is a FOTA server.

Please refer to fig. 9. Preferably, before step S104, that is, before the wearable device decompresses the upgrade package to the cache partition, the method further includes:

S104A, the wearable device cleans up garbage files of the cache partition.

By cleaning the junk files, the residual space of the cache partition is increased as much as possible. The garbage cleaning program can be started and operated automatically by the operating system, and can also be started and operated manually by a user.

Please refer to fig. 10. Further, the wearable device in step S104 decomposes the upgrade package into a plurality of decomposed sub-packages, specifically including:

S104B, the wearable device decomposes the upgrade package into a first decomposition sub-package, wherein the first decomposition sub-package comprises a patch package, an img package and an add package.

The upgrade package is decomposed into a plurality of first decomposition sub-packages by decomposing the upgrade package.

Please refer to fig. 11. Further, step S104, namely, the wearable device decompresses the upgrade package to the cache partition (see step S1040), and decomposes the upgrade package into a plurality of decomposition sub-packages, which specifically includes:

S104B, the wearable device decomposes the upgrade package into a plurality of first decomposition sub-packages;

And S104C, the wearable device decomposes the first decomposition sub-packet with the occupied space being larger than or equal to a preset value B for one or more times until the occupied space of all the decomposition sub-packets is smaller than the preset value B or the decomposition sub-packets cannot be decomposed continuously.

It should also be noted that: the preset value B can also be the same as the preset value A; the preset value B is less than or equal to the preset value A; the preset value C is less than or equal to the preset value A.

For example: the img package and the add package are larger in general, and the img package and the add package can be subjected to a second decomposition operation according to conditions.

If the file volumes of all the first decomposition sub-packages are smaller than the preset value a, the upgrade package decomposition operation is finished, and step S105 is performed next; if the first decomposition packet is traversed after one decomposition, and one or a plurality of file volumes are found to be larger than the preset value B, the decomposition operation is further required to be continued until the file volumes of all the decomposition sub-packets are smaller than or equal to the preset value B or all the decomposition sub-packets are already divided into the minimum units.

If the volume of the file in the sub-package is still greater than half of the remaining space in the system partition after the disassembly operation, the user is required to manually clean the file or clean the file in the storage space based on rules established by the user.

When the garbage files (such as garbage files of the system partition) are cleaned, and the file volume of the decomposed sub-package is still more than half of the residual space of the system partition, a notification that the upgrade operation is not recommended should be sent to the user.

And, the wearable device should also send a notification to the server, the server will reduce the frequency of pushing the upgrade package to the machine type after receiving the notification, if the server receives a certain number of such notifications in a cumulative way, the server temporarily closes the upgrade package automatic download service of the wearable device until the user downloads the upgrade package or the upgrade package manually.

Please refer to fig. 12. Further, after step S104C, that is, after the space occupied by all the decomposed sub-packets is smaller than the preset value B or the decomposed sub-packets cannot continue to be decomposed, the method further includes:

S105A, if the largest space occupied by the decomposition sub-package is more than half of the rest space of the system partition, the wearable device prompts a user to clear the space;

and S105B, if the space of the decomposition sub-packet with the largest space is less than or equal to half of the rest space of the system partition, the wearable device upgrades each decomposition sub-packet respectively, and immediately clears the decomposition sub-packet after the upgrade of each decomposition sub-packet is finished until all the decomposition sub-packets are upgraded.

It is easily understood that when the space of the largest decomposition sub-packet is equal to or less than half of the remaining space of the system partition, the space of all the decomposition sub-packets is equal to or less than half of the remaining space of the system partition.

Preferably, when generating the split sub-packages, the wearable device assigns a unique file tag or number to each split sub-package.

After each decomposition sub-packet is upgraded, the wearable device releases the storage space occupied by the decomposition sub-packet by clearing the decomposition sub-packet, so that the consumption of the storage space can be saved as much as possible.

Please refer to fig. 13. Further, before step S104, the method further includes:

and S103C, the wearable device sends a message to the server, so that the server simulates the upgrade package into packages.

The S103C specifically includes:

S103C1, the wearable device sends a request to a server, so that the server virtually generates a virtual wearable device which is the same as or similar to the situation of the residual space of the system partition of the wearable device;

S103C2, the wearable device sends a notification to the server, so that the server performs subcontracting operation on the virtual wearable device;

S103C3, the wearable device receives a message that the subpackaging operation sent by the server is completed, and judges whether the situation that twice the file volume is larger than the residual space size of the system partition exists in the decomposed subpacket or not, if so, the wearable device continues to execute the following steps;

And S103D, the wearable device receives the message sent by the server, and the wearable device interrupts the upgrading operation or notifies the user to manually clear the storage space.

Preferably, the virtual wearable device may be generated by a virtual machine or the like. After the simulation sub-packaging is finished, the server deletes the virtual wearable device.

By simulating sub-package operation in advance at the server, the possibility of upgrading failure is discovered in advance as much as possible, so that the upgrading success rate is improved.

Please refer to fig. 14. Further, after step S105, that is, after dynamically processing the update_script upgrade script according to the number of packets, the method further includes:

s1051, the wearable device receives a touch operation confirming the system update, or,

s1052, the wearable device determines the time of system update according to rules preset by a user. For example: the user preset 00 per monday: 30-01: 30.

Step S1051 corresponds to a manual mode, in which the user determines whether to agree with the current update by touching the interactive operation; the above step S1052 corresponds to an automatic mode which is automatically handled by the wrist machine operating system. The wrist machine may send out a confirmation popup window to the user on the display screen, if the user clicks the confirmation button in the popup window, step S1052 is not performed any more, and if the user ignores the popup window, the wrist machine performs step S1052.

Since the wearable device has a period of time that is not available during the system upgrade, the user performs the upgrade by confirming the upgrade operation or selecting an appropriate time.

The following will further explain the step S1052 as an example.

Please refer to fig. 15. Further, before step S1052, the method further includes:

s1053, the wearable device monitors the motion state, and if the wearable device is in motion (for example, a user wears a wrist machine to walk, run, play ball and the like), the time for executing the step S106 is automatically delayed; if the wearable device is in rest, the wearable device performs step S1052.

The intervals of the automatic deferral time may be in the form of fibonacci sequences or other forms. If in the form of a fibonacci sequence, the first time is deferred for 1 hour, the second time is deferred for 2 hours, the third time is deferred for 3 hours, the fourth time is deferred for 5 hours, the fifth time is deferred for 8 hours, the sixth time is deferred for 13 hours, the seventh time is deferred for 21 hours … …, and so on. In this way, the user is prevented from being disturbed as much as possible. It should also be noted that in other embodiments of the present invention, if the step of automatically deferring time occurs, reference may also be made to the scheme of automatically deferring time herein.

Further, when the user of the wearable device is in a sleep state, the system automatically performs step S106. The user wears the wearable device (such as the wrist machine) to sleep, and meanwhile, the current time is judged, so that whether the user is in noon break or in the evening is judged, and wrist machine upgrading is carried out in the evening sleeping time period of the user. Detecting whether the user is in a sleep state may use existing sleep detection methods, such as: and judging whether the user enters a sleep state or not by monitoring the heart rate of the user and the like. More preferably, the updating operation of the wearable device is performed after the user enters the deep sleep state. Of course, if the user enters a light sleep, an update operation of the wearable device may also be performed.

In order to more accurately evaluate the time of the upgrade operation, the wrist machine can establish a sleep model of the user, establish a model of sleep habit of the user by collecting physical sign data of the user, predict sleep time of the user by using the model, and set the wrist machine upgrade time within the predicted time range by calling the predicted sleep time data.

For example: by analyzing the sign data of user a for several consecutive days, it follows: 23:30-7: 30, the user is in an evening sleep state, wherein the deep sleep time is 2:00-5:00; and the space between 13:00 and 14:00 is in a noon break state. The wrist machine operating system can set the time for system upgrade to be 2:00-5:00.

When the sleeping habits of the user change, the upgrading time of the wrist machine also changes. For example: user a: and the sleeping state is between 8:00 and 16:00, wherein the deep sleeping time is between 10:00 and 11:30. Then the wrist machine operating system may set the system upgrade time to 10:00-11:30. Such a change in sleep habits may occur when the user needs a shift between day shift and night shift, and the sleep time of the user may be changed accordingly.

Please refer to fig. 16. Further, before step S1052, the method further includes:

s1054, the wearable device monitors the noise intensity in the current environment, and if the noise intensity is lower than a preset value E, the step S1053 is executed; if the noise intensity is higher than the preset value E, the execution of the step S106 is automatically delayed.

The preset value E is a noise measurement index, for example: preset value e=70 db.

Step S1054 mainly considers: if the wearable device is in a noisy environment, it may be due to the fact that the user is working (e.g. meeting, negotiating), working outdoors (e.g. shopping, participating in concert), taking a vehicle (e.g. sitting on train, high-speed rail, subway, airplane, ship), etc., and it is not appropriate to upgrade the system of the wearable device.

Further, even if the user is in deep sleep at this time, the user may have poor sleep quality if the user is in a loud noise, and thus the user may wake up at any time, so even if the user is in a deep sleep state as determined by S1053, the operating system of the wrist machine will automatically delay the upgrade time if the user is in a noisy noise environment as determined by S1054. For example: the deep sleep time of the user A is 2:00-5:00, the user A is riding on a train sleeper at 3:00, and the user enters deep sleep at the moment, but the user possibly wakes up at any time on the train, so that the wrist machine automatically delays the upgrade plan at the moment.

Please refer to fig. 17. Further, after step S1052, further including:

s1055, the wearable device monitors the residual electric quantity, and if the residual electric quantity is higher than a preset value D, step S1054 is executed; if the remaining power is lower than the preset value D, the wearable device prompts the user to charge, and automatically delays the execution of step S106.

The preset value D may be an absolute remaining power value or a ratio of the remaining power to the actual capacity of the battery, for example: the preset value D is 50%.

Step S1055 mainly considers that the wearable device needs to maintain a sufficient amount of power when performing the upgrade operation.

Preferably, the wearable device performs S1055 first, then S1054, then S1053, and then S1052. That is, if the remaining power of the wearable device meets the upgrade requirement, further judging whether the environment where the wearable device is located is suitable for upgrade, if the environmental noise is low, indicating that the user is in a quieter environment, further judging whether the wearable device is in a motion state, and if the wearable device is in a quieter state, determining the upgrade time by the wearable device according to rules preset by the user.

For example:

1. the residual electric quantity of the wearable device is 70%, the wearable device is positioned in a gymnasium with environmental noise of 40 dB, and the wearable device delays the upgrading time because the wearable device is in a motion state;

2. the residual electric quantity of the wearable device is 75%, and the wearable device is in a bedroom with environmental noise of 30 dB, and the wearable device monitors that the user is in a sleep state; and according to the sleeping habit of the user, the wearable device judges that the user still sleeps for a period of time, and the wearable device executes system upgrading.

Further, the wearable device may sequentially perform one of steps S1055, S1054, S1053

Or two steps or all three steps, and then step S1052 is performed.

The wearable device performs steps S1055, S1054, S1053 to reduce the impact of system upgrade

The chance that the user is using the wearable device normally.

Of course, if the wearable device is in a charged state and the remaining power is higher than the preset value F (e.g., preset value d=30%), the wearable device also meets the power condition required for upgrading. That is, an alternative step of S1055:

s1056, the wearable device monitors whether the wearable device is in a charging state, if so, the wearable device periodically checks (for example, checks every 5 minutes) whether the residual electric quantity of the self-charging battery is higher than a preset value F, and if so, the step S106 is executed.

Please refer to fig. 18. Further, step S101, that is, the wearable device detects an upgrade package, includes:

s1011, the wearable device sends a request for acquiring an upgrade package to the FOTA server through a network at regular time;

s1012, the wearable device receives a notification that an upgrade package sent by the FOTA server is updated;

S1013, the wearable device downloads the upgrade package from the FOTA server.

Referring to fig. 21, the wrist machine is connected to the server through an intermediate network, where the intermediate network is the internet.

The wearable device can periodically check whether an upgrade package or an update package of the current model adaptation exists or not to the FOTA server (a background server of a manufacturer), and if the upgrade package exists, the FOTA server sends a corresponding notification to the wearable device.

Please refer to fig. 19. Further, step S106, after upgrading each of the split sub-packets, and immediately clearing the split sub-packets by the wearable device after the upgrading of each of the split sub-packets is completed, further includes:

and S107, the wearable device informs the FOTA server that the upgrading is completed.

Please refer to fig. 20. Further, before step S106, that is, before each of the decomposed sub-packets is upgraded separately, the method further includes:

S106A, carrying out integrity check on each decomposed sub-packet.

The integrity check ensures that the decomposed subpacket is complete and free of data loss.

Further, the wrist machine may generate a check code (such as MD5 code) for each sub-packet, then transmit the check code to the server through the network, and the server determines whether the sub-packet is complete by verifying the check code, and if the sub-packet is incomplete, the server notifies the wrist machine to regenerate the sub-packet and perform the verification again.

Example 2

According to embodiment 1, the upgrade package may be decomposed to obtain a plurality of decomposed sub-packages. If the file volume of all the sub-packages is smaller than half of the residual space of the system partition, the sub-packages can be upgraded one by one according to the upgrade script.

In the upgrading process of the sub-packages, the execution sequence of the sub-packages can be further optimized. While a split sub-packet is deleted immediately every time it is upgraded as the upgrade proceeds, the remaining space of the system partition may also exhibit a gradual trend as the system is running. Therefore, it is preferable to preferentially upgrade the large-size sub-package of the file.

Please refer to fig. 22. In fig. 22, the upgrade package is 455M (english: MByte, megabyte), and since the space occupied by the upgrade package is larger than the preset value a (the preset value a takes 200M), the 1 st decomposition is performed, and the 1 st classification results: a patch package of 10M, an img package of 350M, an add package of 95M; because the space occupied by the img packet is larger than the preset value B (the preset value B takes 100M), the 2 nd decomposition is executed, and the method is obtained through the 2 nd decomposition: a decomposition sub-packet 1 of 250M, a decomposition sub-packet 2 of 100M; because the space occupied by the decomposition sub-packet 1 is larger than the preset value B (the preset value B takes 100M), the 3 rd decomposition is executed, and the 3 rd decomposition is carried out to obtain: 200M of a decomposition sub-packet 3, 50M of a decomposition sub-packet 4; because the space occupied by the decomposition sub-packet 3 is larger than the preset value B (the preset value B takes 100M), the 4 th decomposition is executed, and the 4 th decomposition is performed to obtain: 160M of decomposed subpackets 5, 40M of decomposed subpackets 6; because the space occupied by the decomposition sub-packet 5 is larger than the preset value B (the preset value B takes 100M), the 5 th decomposition is executed, and the 5 th decomposition is carried out to obtain: 70M split sub-packet 7, 90M split sub-packet 8.

When the upgrade package is decomposed, a tree structure is formed, all leaf nodes on the tree are decomposition sub-packages, and the wearable equipment upgrades each decomposition sub-package respectively.

Please refer to fig. 23. In order to optimize the upgrading sequence of the decomposed sub-packets, huffman tree is adopted for optimization. And taking the file volume as a weight, so that the decomposition sub-packet with larger file volume is closer to the root node. That is, at the time of upgrading, the upgrading order of the respective decomposed sub-packages is: the sub-package 2, add package, sub-package 8, sub-package 7, sub-package 4, sub-package 6 and patch package.

The decomposition tree is constructed into a Huffman binary tree, so that the upgrade operation can be smoother. By preferentially upgrading the decomposition sub-package with larger file volume, the problem that the decomposition sub-package with larger file volume cannot be upgraded due to upgrading of the decomposition sub-package with smaller file volume is avoided. In particular, if the update sequence of the sub-packet is relatively low, the remaining space of the system partition may change during the update process, so that the update packet cannot be updated successfully. Embodiment 2 optimizes the upgrade order of the decomposed sub-packages by constructing an optimal tree, and further provides the probability of successful upgrade of the wrist machine.
