Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In some scenarios, data needs to be transmitted in real time through a network, for example, when monitoring places such as a bar, a hotel, and the like, a monitoring image needs to be uploaded to a platform through the network in real time, and the platform analyzes and processes the monitoring image.

However, the network status of these scenarios may not be stable, and data loss may result from data transmission through the network with unstable status.

In order to solve the above technical problem, the present invention provides a method for resuming network interruption, which can be applied to various electronic devices with Embedded multimedia memory cards installed thereon, such as a computer with an Embedded Multimedia Memory Card (EMMC) installed thereon, a mobile terminal, a webcam, a ball machine, and the like, and is not limited thereto in the embodiments of the present invention.

The method for resuming the disconnected network provided by the embodiment of the invention is generally explained as follows:

judging whether the state of the electronic equipment meets a transmission condition or not; wherein the state of the electronic device comprises: network card status and/or remaining capacity status of the buffer;

if the transmission data does not meet the requirement, adding a continuous transmission mark for the data to be transmitted as continuous transmission data;

As can be seen from the above, in the disconnected network continuous transmission method provided in the embodiment of the present invention, by determining whether the state of the electronic device satisfies the transmission condition, if not, a continuous transmission flag is added to the data to be transmitted, and the data to be transmitted is used as continuous transmission data and stored in the embedded multimedia memory card; if the duration that the electronic equipment does not transmit data through the network reaches the preset duration, uploading the continuous transmission data stored in the embedded multimedia memory card; wherein the state of the electronic device comprises: the network card state and/or the residual capacity state of the buffer area, wherein the network card state can reflect whether the electronic equipment is networked, the residual capacity state of the buffer area reflects the data volume of the data to be transmitted which is not uploaded in the buffer area, and if the residual capacity of the buffer area is larger, the current network transmission speed is reflected to be slower, and the transmission requirement of the data cannot be met; therefore, when the state of the electronic equipment does not meet the transmission condition, the data to be transmitted can be determined as the continuous transmission data, and after a period of time, the data to be transmitted is uploaded again, rather than being directly transmitted under the condition that the electronic equipment is not networked or the network transmission speed is low, so that the data loss is reduced.

The method for resuming transmission of a disconnected network provided by the embodiment of the present invention is described in detail by the following specific embodiments.

As shown in fig. 1, a schematic flow chart of a network interruption and continuous transmission method provided in an embodiment of the present invention is applied to an electronic device installed with an embedded multimedia memory card, and includes the following steps:

s101: and acquiring data to be transmitted, and storing the data to be transmitted to a buffer area.

The data to be transmitted is data to be uploaded to a network by the electronic device, for example, the data to be transmitted may be video data acquired by an electronic device such as a network camera or a dome camera, or document data generated by an electronic device such as a computer or a mobile terminal, and the details are not limited.

After the data to be transmitted is obtained, the data to be transmitted can be stored in a buffer area of the electronic equipment, the data to be transmitted stored in the buffer area is uploaded to a network, and if the data to be transmitted is uploaded successfully, the data to be transmitted stored in the buffer area is deleted. For example, in an electronic device, a buffer may be quantized and allocated to 42 units, and in an initial state, the structure array pointer corresponding to each unit does not point to any address, and if a unit is occupied, it indicates that the electronic device allocates an address to the unit, and the structure array pointer corresponding to the unit points to the address allocated to the unit. After the data to be transmitted is obtained, the unoccupied cells may be determined in the 42 cells, corresponding addresses are allocated to the determined cells, the data to be transmitted is written into the allocated addresses, and each cell may write a group of data to be transmitted.

In one implementation, whether a Secure Digital Memory Card (SD Card) is installed in a Card slot of an electronic device may be detected, and if yes, the data to be transmitted may be stored in the SD Card after the data to be transmitted is acquired, so as to backup the acquired data to be transmitted.

S102: judging whether the state of the electronic equipment meets the transmission condition or not; wherein the state of the electronic device comprises: network card status and/or remaining capacity status of the buffer; if not, S103 is executed.

Further, whether the state of the electronic equipment meets the transmission condition or not can be judged, if yes, when the electronic equipment uploads the data to be transmitted to the network, the probability of transmission failure is low, data loss is not easy to occur, and under the condition, the data to be transmitted can be uploaded; if the transmission failure rate does not meet the requirement, it is considered that when the electronic device uploads the data to be transmitted to the network, the probability of transmission failure is high, and data loss is easy to occur, in this case, the data to be transmitted is not uploaded first, and S103 is executed.

In one implementation manner, whether the state of the electronic device meets the transmission condition may be determined by the network card state of the electronic device. Specifically, the network card status of the electronic device may be obtained first, where the network card status includes a networking status and a network disconnection status, the networking status indicates that the electronic device is well connected to the network, and the network disconnection status indicates that the electronic device is not well connected to the network, or that the electronic device has been disconnected from the network. It can be understood that when the connection condition of the electronic device and the network is good, the possibility of sending errors of the data to be uploaded is low, and when the connection condition of the electronic device and the network is not good or the electronic device is disconnected from the network, the possibility of sending errors of the data to be uploaded is high. In this case, if the network card status is the networking status, it is determined that the status of the electronic device satisfies the transmission condition, and if the network card status is the disconnection status, it is determined that the status of the electronic device does not satisfy the transmission condition.

Alternatively, in another implementation, whether the state of the electronic device satisfies the transmission condition may be determined by the remaining capacity state of the buffer. The data to be transmitted can be uploaded to the network through the buffer, and after the data to be transmitted is uploaded successfully, the data to be transmitted can be deleted from the buffer, the capacity of the buffer can not be occupied, under the condition, whether the residual capacity is larger than a preset threshold value or not can be judged through acquiring the residual capacity of the buffer, so that whether the data to be transmitted is uploaded to the network in time or not is judged, if the residual capacity in the buffer is not larger than the preset threshold value, it is indicated that the current network transmission speed cannot meet the transmission requirement of the data to be transmitted, and a large amount of data to be transmitted is stored in the buffer and cannot be uploaded to the network in time.

For example, the remaining capacity of the buffer may refer to the remaining amount of the memory of the buffer, for example, if the total memory of the buffer is 128MB and the currently occupied capacity is 100MB, the remaining amount of the memory of the buffer is 28MB. Therefore, whether the residual value of the memory of the buffer area is larger than a preset threshold value or not can be judged, if so, the fact that the data to be transmitted in the buffer area can be uploaded to the network in time is shown, the data to be transmitted uploaded to the network cannot be stored in the buffer area and cannot occupy the capacity of the buffer area is shown, under the condition, the fact that the state of the electronic equipment meets the transmission condition can be judged, if not, the fact that the data to be transmitted in the buffer area cannot be uploaded to the network in time but is stored in the buffer area and occupies the capacity of the buffer area is shown, and under the condition, the fact that the state of the electronic equipment does not meet the transmission condition can be judged.

Or, the remaining capacity of the buffer may refer to a memory threshold of the buffer, where the memory threshold of the buffer is a ratio of the number of remaining units of the buffer to the total number of units of the buffer, for example, if the buffer is quantized and divided into 42 sub-units, each sub-unit can only store one picture, and if 20 pictures are currently stored, the remaining 22 units are not occupied, and the memory threshold of the buffer is 55%. In this way, the memory threshold of the buffer area may also be calculated according to the remaining capacity of the buffer area, and whether the memory threshold is greater than the preset threshold is determined, where the preset threshold may be an empirical value, such as 30%. If the memory threshold is greater than the preset threshold, the number of the unoccupied residual units is enough, that is, the data to be transmitted in the buffer area can be uploaded to the network in time, and under the condition, the state of the electronic equipment can be judged to meet the transmission condition; if the memory threshold is not greater than the preset threshold, it indicates that the number of the unoccupied remaining cells is not enough, that is, the data to be transmitted in the buffer cannot be uploaded to the network in time, and in this case, it may be determined that the state of the electronic device does not satisfy the transmission condition.

In another implementation manner, whether the state of the electronic device meets the transmission condition may be determined by the network card state of the electronic device and the remaining capacity state of the buffer area. Specifically, a network card status of the electronic device may be obtained first, where the network card status includes: a disconnected state or a connected state; if the network card state is the networking state, further acquiring the residual capacity of the buffer area, and judging whether the residual capacity is larger than a preset threshold value; if so, judging that the state of the electronic equipment meets the transmission condition; if not, judging that the state of the electronic equipment does not meet the transmission condition; and if the network card state is the disconnected network state, judging that the state of the electronic equipment does not meet the transmission condition.

Or, the remaining capacity of the buffer area may be obtained first, and whether the remaining capacity is greater than the preset threshold value is judged; if the current network card state is greater than the preset network card state, further acquiring a network card state of the electronic device, wherein the network card state comprises: a disconnected state or a connected state; if the network card state is the networking state, judging that the state of the electronic equipment meets the transmission condition; and if the network card state is a disconnected network state or the residual capacity is not greater than a preset threshold value, judging that the state of the electronic equipment does not meet the transmission condition.

The judgment of the network card status of the electronic device and the residual capacity status of the buffer area can be performed simultaneously or sequentially, and is not limited specifically.

S103: adding a continuous transmission mark for the data to be transmitted as continuous transmission data; and storing the continuous transmission data into the embedded multimedia memory card.

If the state of the electronic device does not meet the transmission condition, a continuous transmission mark can be added to the data to be transmitted to serve as continuous transmission data, and then the continuous transmission data are stored in the EMMC.

In some cases, frequent erasing and writing of the EMMC may affect the system code and configuration file stored in the EMMC, resulting in program exception, and in this case, it may be determined whether to store the resume data in the EMMC according to the state of the EMMC, thereby protecting the EMMC.

Specifically, before the continuous transmission data is stored in the EMMC, the state of the EMMC can be acquired, whether the EMMC reaches an early warning state or not is judged, if the EMMC does not reach the early warning state, the EMMC can be stably used without causing program exception, and then the continuous transmission data is stored in the EMMC; if this is achieved, it is indicated that the EMMC may not be used stably, and even cause program exceptions, in which case the set of resume data may be discarded. The service life of the EMMC can be determined according to the write-in quantity and the amplification factor of the EMMC, whether the service life of the EMMC is smaller than a preset early warning threshold value or not is further judged, if yes, the EMMC is judged to reach an early warning state, and if not, the EMMC is judged not to reach the early warning state.

Specifically, in one implementation, the processor may obtain the used percentage of the EMMC through the extension register, the used percentage of the EMMC recorded in the extension register is divided into 10 levels, and each time a level is reached, the amplification factor may be calculated once, so as to calculate the service life of the EMMC. For example, taking two scenes, namely, a video stored by a network camera or a picture stored by a face snapshot machine as an example, in the two scenes, generally, the amplification factor is relatively stable, and 24 hours of data is used in the calculation, and the service life of the EMMC can be determined by using the following formula:

WAI＝EXT_CSD×C×3000/S

LifeTime＝(C×3000)/(L×WAI)×24

wherein WAI represents the amplification factor, EXT _ CSD represents the used percentage of EMMC, C represents the total capacity of EMMC, S represents the total bytes written for EMMC, life time represents the life of EMMC, and L represents the write capacity of EMMC in the last 24 hours.

In the case that it is determined that the EMMC reaches the warning state, if it is detected that the SD card is installed in the card slot of the electronic device, that is, the data to be transmitted is backed up in the SD card, in one implementation, a continuous transmission flag may be added to the set of data to be transmitted that is determined as continuous transmission data in the SD card, and if the storage capacity of the SD card also reaches the threshold, the set of continuous transmission data is discarded.

In one implementation, the encryption interface may be invoked to encrypt the resume data, and then the encrypted resume data is stored in the EMMC, so that information leakage in the stored resume data may be reduced.

S104: and if the duration that the electronic equipment does not transmit data through the network reaches the preset duration, uploading the continuous transmission data stored in the embedded multimedia memory card.

Generally, when data transmission is performed on electronic equipment through a network, data to be transmitted which are acquired in real time are transmitted first, and when the duration of data transmission which is not performed on the electronic equipment through the network reaches a preset duration, it indicates that the data to be transmitted which are not acquired in real time are transmitted currently, and continuous transmission data stored in an embedded multimedia memory card can be uploaded. The preset threshold may be 30 seconds, or may be other empirical values or preset values, which are not limited specifically.

Specifically, the continuous transmission data stored in the EMMC may be uploaded, and then, whether the continuous transmission data is successfully uploaded is determined, and if the continuous transmission data is successfully uploaded, the continuous transmission flag of the continuous transmission data may be directly deleted, or the continuous transmission flag of the continuous transmission data may be modified into the non-continuous transmission flag.

If the SD card is installed in the electronic equipment and the continuous transmission data is stored in the SD card, the continuous transmission data stored in the SD card can be uploaded, then whether the continuous transmission data is successfully uploaded is judged, and if the continuous transmission data is successfully uploaded, the continuous transmission mark of the continuous transmission data can be deleted or modified into the continuous transmission mark. When the continuous transmission data is uploaded, the continuous transmission data can be uploaded in sequence from morning to evening according to the acquisition time of the continuous transmission data, and the continuous transmission data is not deleted after the continuous transmission data is successfully uploaded, so that the query is facilitated.

For example, in an implementation manner, the data to be transmitted may be face pictures, as shown in fig. 2, the data is in a storage format stored in the EMMC, each group of face pictures is stored in a picture pool allocated to the EMMC, information such as a picture sequence number, a picture alarm type, an alarm time, a picture number, a corresponding picture pool offset start address, a picture pool end address, and the like, and flag information indicating whether the group of picture alarm data is a resume data are recorded in the picture index information, where the flag information is 1 when the group of picture alarm data is the resume data, and the flag information is 0 in an initial state or after the group of picture alarm data is successfully uploaded.

When the continuous transmission data is uploaded, the continuous transmission data can be uploaded from the morning to the evening according to the acquisition time of the continuous transmission data, the continuous transmission data can not be deleted after the continuous transmission data is successfully uploaded, and when new continuous transmission data is stored in the EMMC, the oldest stored continuous transmission data in the EMMC can be directly covered.

Further, if the continuous transmission data is encrypted when the continuous transmission data is stored in the EMMC, the decryption interface needs to be called to decrypt the stored continuous transmission data when the continuous transmission data is uploaded, and the decrypted continuous transmission data is uploaded.

As can be seen from the above, in the disconnected network continuous transmission method provided in the embodiment of the present invention, by determining whether the state of the electronic device satisfies the transmission condition, if not, a continuous transmission flag is added to the data to be transmitted, and the data to be transmitted is used as continuous transmission data and stored in the embedded multimedia memory card; if the duration that the electronic equipment does not transmit data through the network reaches the preset duration, uploading the continuous transmission data stored in the embedded multimedia memory card; wherein the state of the electronic device comprises: the network card state and/or the residual capacity state of the buffer area, wherein the network card state can reflect whether the electronic equipment is networked, the residual capacity state of the buffer area reflects the data volume of the data to be transmitted which is not uploaded in the buffer area, and if the residual capacity of the buffer area is larger, the current network transmission speed is reflected to be slower, and the transmission requirement of the data cannot be met; therefore, when the state of the electronic equipment does not meet the transmission condition, the data to be transmitted is determined as the data to be continuously transmitted, and the data to be transmitted is uploaded again after a period of time, rather than being directly transmitted under the condition that the electronic equipment is not networked or the network transmission speed is low, so that the data loss is reduced.

As shown in fig. 3, a schematic flow chart of another method for resuming network transmission on a disconnected network according to an embodiment of the present invention is applied to an electronic device with an embedded multimedia memory card installed therein, and includes the following steps:

s301: and acquiring data to be transmitted, and storing the data to be transmitted to a buffer area.

Generally, after obtaining the data to be transmitted, the data to be transmitted may be stored in a buffer of the electronic device, and then the data to be transmitted stored in the buffer is uploaded to the network, and if the data to be transmitted is uploaded successfully, the data to be transmitted stored in the buffer is deleted. For example, in an electronic device, a buffer may be quantized and allocated to 42 units, and in an initial state, a pointer of a structure array corresponding to each unit does not point to any address, and if a unit is occupied, it indicates that the electronic device allocates an address to the unit, and a pointer of a structure array corresponding to the unit points to the address allocated to the unit. After the data to be transmitted is obtained, the unoccupied cells may be determined in the 42 cells, corresponding addresses are allocated to the determined cells, the data to be transmitted is written into the allocated addresses, and each cell may write a group of data to be transmitted.

S302: and storing the data to be transmitted into the secure data memory card.

In an implementation manner, whether a Secure Digital Memory Card (Secure Digital Memory Card) is installed in a Card slot of an electronic device may be detected, and if so, data to be transmitted may be stored in the SD Card after the data to be transmitted is acquired, so that the acquired data to be transmitted is backed up.

S303: acquiring the network card status of the electronic device, if the network card status is the networking status, executing S304, and if the network card status is the network disconnection status, executing S305.

Specifically, the network card status may be obtained first, where the network card status includes a networking status and a network disconnection status, the networking status indicates that the connection condition of the electronic device and the network is good, and the network disconnection status indicates that the connection condition of the electronic device and the network is not good, or that the electronic device has been disconnected from the network. It can be understood that when the connection condition of the electronic device and the network is good, the possibility of sending errors of the uploaded data to be transmitted is low, and when the connection condition of the electronic device and the network is not good or the electronic device is disconnected from the network, the possibility of sending errors of the uploaded data to be transmitted is high. In this case, if the network card status is the networking status, it is determined that the status of the electronic device satisfies the transmission condition, and if the network card status is the disconnection status, it is determined that the status of the electronic device does not satisfy the transmission condition.

S304: acquiring the residual capacity of the buffer area, and judging whether the residual capacity is greater than a preset threshold value; if the number is larger than the preset value, transmitting data to be transmitted; if not, S305 is executed.

The data to be transmitted can be uploaded to the network through the buffer, and after the data to be transmitted is uploaded successfully, the data to be transmitted can be deleted from the buffer, the capacity of the buffer can not be occupied, under the condition, whether the residual capacity is larger than a preset threshold value or not can be judged through acquiring the residual capacity of the buffer, so that whether the data to be transmitted is uploaded to the network in time or not is judged, if the residual capacity in the buffer is not larger than the preset threshold value, it is indicated that the current network transmission speed cannot meet the transmission requirement of the data to be transmitted, and a large amount of data to be transmitted is stored in the buffer and cannot be uploaded to the network in time.

For example, the remaining capacity of the buffer may refer to the remaining amount of the memory of the buffer, for example, if the total memory of the buffer is 128MB and the currently occupied capacity is 100MB, the remaining amount of the memory of the buffer is 28MB. Therefore, whether the residual value of the memory of the buffer area is larger than a preset threshold value or not can be judged, if so, the data to be transmitted in the buffer area can be timely uploaded to the network under the current network state, the data to be transmitted uploaded to the network cannot be stored in the buffer area, and the capacity of the buffer area cannot be occupied.

S305: judging whether the embedded multimedia memory card reaches an early warning state or not; if so, executing S307; if not, go to step S306.

In some cases, frequent erasing of the EMMC may affect critical system code and configuration files stored in the EMMC, resulting in program exception, and in this case, it may be determined whether to store the resume data in the EMMC according to the state of the EMMC, thereby protecting the EMMC.

The service life of the EMMC can be determined according to the write-in quantity and the amplification factor of the EMMC, whether the service life of the EMMC is smaller than a preset early warning threshold value or not is further judged, if yes, the EMMC is judged to be in an early warning state, and if not, the EMMC is judged not to be in the early warning state.

Specifically, in one implementation, the used percentage of the EMMC may be obtained through an extension register, the used percentage of the EMMC recorded in the extension register is divided into 10 levels, and each time a level is reached, an amplification factor may be calculated once, so as to calculate the service life of the EMMC. For example, taking two scenes, i.e., a video stored in a network camera or a picture stored in a face capture machine as an example, in the two scenes, generally, the amplification factor is relatively stable, 24 hours of data is used in calculation, and the service life of the EMMC can be determined by using the following formula:

WAI＝EXT_CSD×C×3000/S

LifeTime＝(C×3000)/(L×WAI)×24

where WAI represents the amplification factor, EXT _ CSD represents the percentage of EMMC that has been used, C represents the total capacity of EMMC, S represents the total bytes written for EMMC, life represents the life of EMMC, and L represents the amount of EMMC that has been written for the last 24 hours.

S306: adding a continuous transmission mark for the data to be transmitted as continuous transmission data; and storing the continuous transmission data into the embedded multimedia memory card.

In this case, the state of the electronic device does not satisfy the transmission condition, and then, a resume flag may be added to the data to be transmitted as resume data, and then, the resume data may be stored in the EMMC.

S307: in the secure data memory card, a continuous transmission mark is added to the data to be transmitted.

In this case, it indicates that the EMMC may not be stably used, and even cause a program exception, whether an SD card is installed in the card slot of the electronic device may be detected, and if so, a resume flag may be added to the set of to-be-transmitted data stores determined as resume data in the SD card, and if not installed or the storage capacity of the SD card has also reached a threshold, the set of resume data is discarded.

S308: and if the duration that the electronic equipment does not transmit data through the network reaches the preset duration, uploading the continuous transmission data stored in the embedded multimedia memory card.

Generally, when data transmission is performed on electronic equipment through a network, data to be transmitted which are acquired in real time are transmitted first, and when the duration of data transmission which is not performed on the electronic equipment through the network reaches a preset duration, it indicates that the data to be transmitted which are not acquired in real time are transmitted currently, and the data to be transmitted stored in the embedded multimedia memory card can be uploaded. The preset threshold may be 30 seconds, or may be other empirical values or preset values, which are not limited specifically.

If the electronic device is provided with the SD card and the continuous transmission data is stored in the SD card, the continuous transmission data stored in the SD card can be uploaded, then whether the continuous transmission data is uploaded successfully or not is judged, and if the continuous transmission data is uploaded successfully, the continuous transmission mark of the continuous transmission data can be deleted or modified into the non-continuous transmission mark. When the continuously transmitted data are uploaded, the continuously transmitted data can be uploaded in sequence from morning to evening according to the acquisition time of the continuously transmitted data, and after the continuously transmitted data are successfully uploaded, the continuously transmitted data are not deleted, so that query is facilitated.

Further, if the continuous transmission data is encrypted when being stored in the EMMC, the decryption interface needs to be called to decrypt the stored continuous transmission data when the continuous transmission data is uploaded, and the decrypted continuous transmission data is uploaded.
