In the embodiment of the invention, in order to realize the playing of the personalized audio and meet more audio playing requirements of the user, before the audio playing is carried out, the user can firstly set the interactive audio of the intelligent door lock in a personalized manner and firstly update the audio. Referring to fig. 1, based on the audio playing method shown in fig. 1, a user may further set an audio used in an interaction process with the smart door lock in a personalized manner, at this time, the user may manipulate a physical key and/or a touch key on the smart door lock to issue an audio adding instruction to the smart door lock, so that the smart door lock adds the audio, and at this time:

and S11, acquiring the newly added audio.

The intelligent door lock can acquire the newly added audio when receiving an audio adding instruction. The default audio is preset when the intelligent door lock leaves a factory, and a user can set own special audio in a personalized manner, namely the newly added audio is the user-defined audio of the user. In this embodiment, the acquired newly added audio may include customized audio files applied in various scenes, such as door opening, door closing, door bell, and alarm scenes.

In the embodiment of the invention, the intelligent door lock can start the microphone to obtain the newly added audio, for example, the microphone arranged on the equipment starting end (such as the intelligent door lock) records the newly added audio. The user may record the user's voice or voice as audio for the smart door lock. In this embodiment, the acquired newly added audio may include customized audio files applied in various scenes, such as door opening, door closing, door bell, and alarm scenes.

In some other examples, the user may download the audio on the network as the audio of the smart door lock, in which case, the user may download the customized audio based on the wired transmission manner and store the customized audio to the preset customized path in the preset file system. The newly added audio can be downloaded based on a wired transmission mode, for example, the intelligent door lock is connected with an upper computer through a connecting line, and the newly added audio is downloaded from the upper computer to the intelligent door lock. The wired transmission may include JTAG interface programming or SWD interface hardware programming. In some other examples, the newly added audio may be downloaded based on a wireless transmission manner, for example, a wireless connection between the smart door lock and a wireless terminal (e.g., a smart phone) may be established, and then the newly added audio may be downloaded to the smart door lock through the wireless terminal, where the wireless transmission may include bluetooth transmission or WIFI transmission.

In the embodiment of the present invention, the audio recorded by the user may be too long and may be noisy, the audio may be modified at this time, that is, the obtained audio may be continuously edited after the newly added audio is obtained, at this time, when the intelligent door lock receives an audio editing instruction, the user may edit the newly added audio based on the physical key or the touch screen, and use the edited audio as the newly added audio, where the audio editing instruction includes at least one of an interception instruction, a newly added instruction, a modification instruction, a deletion instruction, and a formatting instruction. And when the editing instruction is an intercepting instruction, intercepting the selected newly added audio. And when the editing instruction is a new adding instruction, continuously adding new adding audio. And when the editing instruction is a modification instruction, modifying the selected newly added audio. And when the editing instruction is a deleting instruction, deleting the selected newly added audio. And when the editing instruction is a formatting instruction, deleting all newly added audio.

And S12, determining the audio attribute of the newly added audio.

In this embodiment, the audio attribute of the newly added audio may include at least one of a user using the newly added audio, an audio volume, and a usage scene type. It should be understood that timbre and timbre preferred by different users are different, and different users can set their own exclusive audio. In addition, the use scene of the newly added audio can be door opening from inside to outside, door opening from outside to inside, alarming, installation and the like.

And S13, updating the newly added audio to a preset file system based on the audio attribute of the newly added audio, wherein the preset file system is a LittleFS file system or a FatFS file system.

Specifically, updating the newly added audio to the preset file system based on the audio attribute of the newly added audio may include various embodiments, which may specifically be as follows:

the first method is as follows: and determining a user using the newly added audio, and updating the newly added audio to an audio storage path of the user in a preset file system. Therefore, when the new audio of the user needs to be played, the audio can be directly called from the audio storage path of the user, and the time consumption is small.

The second method comprises the following steps: and determining the audio volume of the newly added audio, and updating the newly added audio to a preset file system according to the audio volume. Therefore, the new audio can be played at the audio volume.

The third method comprises the following steps: determining the usage scene type of the newly added audio, and updating the newly added audio to a preset file system according to the usage scene type. Therefore, the new audio can be played in the use scene.

The method is as follows: and renaming an audio storage path of the newly added audio in the preset file system based on the audio attribute of the newly added audio. Therefore, when the newly added audio needs to be played, the newly added audio can be called and played quickly.

Of course, updating the newly added audio to the preset file system based on the audio attribute of the newly added audio may include multiple embodiments, may also be a combination of any two of the four embodiments, a combination of any three of the four embodiments, and may even be a combination of the four embodiments.

In some embodiments, after the microphone is started to obtain the newly added audio, the newly added audio can be directly stored in a preset custom path in a preset file system; after the newly added audio is downloaded based on a wired transmission and/or wireless transmission mode, the newly added audio can be directly stored to a preset custom path in a preset file system.

Further, after the newly added audio is stored in the preset file system, an audio change instruction can be received, and the audio in the preset file system can be deleted, modified or replaced according to the audio change instruction.

In the embodiment of the invention, the LittleFS file system or the FatFS file system is used for performing read-write management on the newly added audio, so that the user can perform custom addition on the audio of the equipment end (such as an intelligent door lock), and the user can manage the newly added audio in modes of adding, changing, deleting, formatting and the like.

The LittleFS file system is an open-source high-integrity file system applied to the embedded field, and has the characteristics of low resource consumption, power failure protection, wear balance, convenience in transplantation and the like. The low resource consumption is that only a small amount of memory space is used, the use of RAM (random access memory) is strictly limited and will not change with the increase of the file system, and the file system does not contain unbounded recursion inside. The power failure protection is that under the condition that the equipment is powered off randomly, the file system has good backup guarantee and can be restored to a last known good state. Wear leveling is that the read-write mechanism of the LittleFS can ensure that FLASH blocks in the file system have balanced erasing probability because the FLASH has the maximum erasing time upper limit. The convenient transplantation, namely the open source code of the LittleFS file system, has a simple structure and is convenient for development and access.

In addition, the FatFS file system is a general file system (FAT/exFAT) module for implementing the FAT file system in a small embedded system. It is characterized in that: (1) DOS/Windows compatible FAT/exFAT file systems; (2) platform independence, ease of use; (3) the program code amount is small, and the occupied resource is low; (4) configuration parameter enrichment

Therefore, the audio updating method can realize the updating of newly added audio through a software method under the condition that resources of embedded equipment such as an intelligent door lock and the like are limited, and meets the personalized customization requirements of users.

As a feasible implementation manner, after the newly added audio is obtained, the type of the newly added audio can be determined; if the type of the audio is the first type, burning the newly added audio into the flash memory with the specified initial address of the equipment end, namely storing the newly added audio into a default path in the flash memory, as shown in fig. 2, wherein the newly added audio of the first type is generated by the server end according to the characteristics of a preset file system; if the type is the second type, the newly added audio is written into the custom path in the flash memory according to the characteristics of the preset file system, as shown in fig. 3.

Specifically, in some examples, when the new audio is delivered in the form of a burning file, the new audio may be packaged at the server in a manner of a directory of a specified hierarchy level according to characteristics of a preset file system, such as a LittleFS file system, to generate a binary file, where the binary file is the first type of bathing energy audio. The binary file is directly burned into a default path in an internal or external FLASH FLASH memory of the specified initial address of the equipment end in a hardware burning mode. The server side and the equipment side can share a set of preset file system, wherein parameters such as memory addresses, space sizes, minimum write sizes, directories, names and the like are kept consistent.

In other examples, when the newly added audio is delivered in a patch manner, the server does not need to encapsulate the customized voice, and the customized voice can be directly transmitted to the device side in a wireless transmission manner. The device side writes the newly added audio into a custom path (as shown in fig. 3, i.e., the above-mentioned preset custom path) according to the characteristics of the preset file system. And if the custom path contains the voice entry with the same name as the newly added audio, the written newly added audio can cover the original voice entry. When the voice broadcast of the corresponding scene is executed, the equipment end can find the latest voice frequency through the file path and broadcast the latest voice frequency.

In one embodiment of the present invention, the first type of added audio may include audio in one or more languages, such as chinese speech, english speech, japanese speech. When new audio of corresponding language is written, the server generates audio of corresponding language according to the characteristics of the preset file system according to the use habit of the user, and then writes the audio into the equipment. For an exemplary, first type of structure of the newly added audio is shown in fig. 2.

It should be noted that the first type of newly added audio can be used as default voice content, and has a read-only property, and the modification right is not exposed to the user. In the voice configuration table shown in fig. 2, a user can set parameters such as a voice path, a version, a volume size, and the like. For example, the default voice path can be changed from the chinese path to the english path, the version of the default audio can be changed, and parameters such as volume can be adjusted through the intelligent door lock app installed on the mobile terminal bound to the intelligent door lock.

As an example, the audio of the smart door lock can be controlled to restore factory settings through a reset key on the smart door lock or through the mobile terminal. After factory setting is restored, other storage paths except the default path in the configuration table are all empty, and the default path is a preset Chinese or English path.

It should be noted that the name of the audio (e.g., a file in mp3 format) in each scene is fixed. For example, in the door opening scenario, the audio obtained by the software is "open _ door. mp 3" or "door open. mp 3", but the path storing the name includes the chinese voice path/cn in the default path, the english voice path/en, or the current voice path/cur in the custom path, as shown in fig. 3.

In one embodiment of the present invention, when the second type of newly added audio is updated to the preset file system, the newly added audio can be written into the custom path in the flash memory. During writing, the user-defined path and the name of the newly added voice can be assembled to obtain a target file path, and the target file path is written into the flash memory, so that the equipment end can read the corresponding newly added voice frequency conveniently. And the name of the newly added audio is the same as the name of the corresponding voice playing scene. It should be noted that, if there is no custom path in the flash memory, as shown in fig. 2, a new custom path is required at this time.

For example, a user can download a personalized voice packet through a mobile terminal app and issue the personalized voice packet to the intelligent door lock through a gateway or a Bluetooth direct connection mode. The intelligent door lock inquires whether the current path (namely the custom path) is empty, if so, a custom path is newly established, and if not, the previously established custom path is used. Finally, the file path "/current path/xxx. mp 3" is formed with the voiced names and written into the flash memory together with the file entries.

Further, in some embodiments, all the second type newly added audios share one custom path, and after the first second type newly added audio is added, the subsequent second type newly added audio does not need to create a new custom path and is directly added to the existing custom path. For example, if the user a adds the individual voice open _ door.mp3 for the first time, and there is no custom path at this time, a custom path/cur _ path is created first, and then a file path/cur _ path/open _ door.mp3 is assembled and written into the flash memory. The subsequent user a adds the personal voice close _ door. mp3, and since/cur _ path already exists, directly assembles the path/cur _ path/close _ door. mp3 and writes it into the flash memory. If the user a wants to add another open _ door.mp3 personality voice again at this time, only updating at the mobile phone end is needed, and the updated/cur _ path/open _ door.mp3 currently directly covers the previous open _ door.mp3 personality voice.

In some embodiments of the present invention, as shown in fig. 4, after updating the new audio to the preset file system based on the audio attribute of the new audio, the method may further include:

and S21, determining that the preset trigger condition is met.

The preset trigger condition is a preset condition for triggering execution of the audio playing method when the condition is met, and in some examples, the preset trigger time may be execution of the audio playing method when an audio playing instruction is received, for example, when a user fingerprint entry is detected, it may be determined that a corresponding audio is played to prompt the user to perform the fingerprint entry when a finger entry interface is entered through a physical key or a touch screen key. In some other examples, the preset triggering time may be a time when the current time is determined to meet the preset time, for example, the going-out reminding time may be preset, and when the current time reaches the set going-out reminding time, it is determined that the preset triggering condition is met, and at this time, the corresponding audio may be played to remind the user of going out. In some other examples, the preset trigger time may be further a determination that the current scene satisfies the preset scene, for example, "welcome home" may be played when the door is opened by the outside; when the door is opened from the inside, the 'attention with key' and 'safety for going out' are played; detecting violent unlocking, or judging that a user is not an actual household when the user tries to unlock for N times but does not successfully unlock, and playing an alarm audio frequency of abnormal unlocking; and when the intelligent door lock detects that someone visits, a visitor-to audio can be played to prompt the user. In addition, the preset trigger condition may also be a preset voice keyword, and when the user sends out a voice corresponding to the keyword, the voice playing instruction is executed to determine that the preset voice keyword is received. For example, the preset speech keywords may include: (1) the operation confirms the voice prompt, for example the user asks "whether the door is locked back", at this moment the intelligent door lock can play the corresponding voice "confirm that the door is locked back" to answer the user; (2) the voiceprint unlocking is carried out, for example, after the voice of a keyword sent by a user is received, the identity of the user needs to be checked, the audio playing method can be executed after the user passes the identity authentication, and the intelligent door lock is prevented from interacting with other people except the resident to waste resources.

And S22, determining the target audio from the preset file system according to the preset trigger condition.

The preset file system comprises a LittleFS file system or a FatFS file system, the LittleFS file system or the FatFS file system is used for performing read-write management on newly added audio, so that the user can perform custom addition on the audio of the equipment end (such as an intelligent door lock), and the user can manage the newly added audio in modes of adding, changing, deleting, formatting and the like. Based on a LittleFS file system or a FatFS file system, the audio updating method provided by the embodiment of the invention can realize the updating of newly added audio through a software method under the condition that resources of embedded equipment such as an intelligent door lock and the like are limited, and meets the personalized customization requirements of users.

It can be understood that the intelligent door lock has different application scenes, the intelligent door lock can play audio corresponding to different conditions, and a large amount of audio is stored in the intelligent door lock. How to determine the target audio from the preset file system according to the preset trigger condition can be realized according to the following method:

newly added audio newly updated in a preset file system can be used as target audio. For example, when the door opening of the house owner is determined according to the preset trigger condition, the newly updated door opening audio can be used as the target audio. The last historically played audio corresponding to the preset trigger condition may also be used as the target audio, that is, when a certain preset trigger condition is determined, the last played audio (historically played audio) corresponding to the certain preset trigger condition may be determined as the target audio, and of course, the preset audio corresponding to the preset trigger condition may also be used as the target audio, in this example, there is an audio corresponding to the preset trigger condition. In addition, the audio corresponding to the preset trigger condition can be inquired in the preset file system according to a preset custom path, if the audio exists, the audio is used as the target audio, otherwise, the audio corresponding to the preset trigger condition is inquired in the preset file system according to a preset default path, and the audio is used as the target audio. It is understood that the audio in the preset custom path may be personalized audio pre-recorded or pre-downloaded by the user, and the default path may be audio preset when the smart door lock leaves the factory. For example, taking a preset scene as an example of a trigger condition, the preset scene is to open a door from inside to outside, determine that the name of the target audio is "door open 1.mp 3", first search for a preset custom path (e.g., the custom path in fig. 3), determine that there is no "door open 1.mp 3", then search for a preset default path (e.g., the default path in fig. 3), and use "door open 1.mp 3" in the default path (e.g., default first selected chinese) as the target audio. It should be noted that the audio in the default path should satisfy all the scene requirements.

And S23, adding the target audio into the play queue to play the target audio.

It is understood that the target audio added to the play queue may be played immediately, may be played with a delay, or may be played when a secondary trigger event occurs after the trigger event corresponding to step S21.

For example, the user prepares to go out and detects that the door is opened from inside to outside, and at this time, the compartment target audio prompts the user to pay attention to the key when the door is opened, which is the above-described directly played target audio in this example; for another example, when the user is not closed after the door is opened, the target audio is played when the time of 30s is met to prompt the user to close the door, which is to play the target audio when the preset time length is met; in addition, after the user opens the door, the target audio can be played when the preset event of closing the door occurs, so that the user can be reminded of taking care of safety on the road, and the example corresponds to playing the target audio when the preset event is determined to occur. In some other examples, after the target audio is determined, if there are two or more target audio, in order to prevent CPU blocking, the target audio may be sequentially inserted into a playlist on the device side for temporary storage, and waiting for playing.

The audio playing method provided by the embodiment of the invention can realize the ordered playing of the audio and can meet the personalized playing requirement of the user on the audio.

The invention also provides a computer readable storage medium.

In this embodiment, a computer program is stored on a computer readable storage medium, and the computer program corresponds to the audio updating method described above, and when being executed by a processor, implements the audio updating method described above.

The invention also provides an intelligent door lock.
