detailed description

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

Embodiments of the present invention provide a data transmission control method and device. The details will be described respectively below.

Embodiment one,

This embodiment will be described from the perspective of a data transmission control device. Specifically, the data transmission control device may be integrated into a terminal, and the terminal may be a smart phone, a tablet computer, or other devices.

A data transmission control method, comprising: determining the target application that currently enables the target sensor; determining the target upload frequency that the buffer corresponding to the target sensor needs to upload data to the processor according to the frequency setting information of the target application; judging the current cache Whether the upload frequency of data uploaded by the device to the processor is equal to the target upload frequency; if not, the depth information of the buffer is adjusted so that the upload frequency is equal to the target upload frequency.

As shown in Figure 1, the data transmission control method, the specific process can be as follows:

101. Determine a target application that currently enables a target sensor.

In some implementations, before determining the target application that currently enables the target sensor, it can be determined whether the current terminal system is in a dormant standby state, and if it is in a dormant state, then determine whether the current target sensor is enabled, that is, determine the target sensor Is it in working condition. If the target sensor is in the working state and the current system is in the dormant state, in order to reduce the power consumption of the terminal, the number of system wake-ups can be reduced; for example, the number of data transmissions to the processor can be reduced to reduce the number of wake-ups of the system.

Specifically, the data acquired by the sensor can be stored in the buffer, and the data can be transmitted to the processor when the buffer is full. Therefore, the storage space of the buffer can be adjusted to the maximum by adjusting the storage parameters of the buffer, such as depth information. , so as to reduce the frequency of uploading data from the buffer to the processor, thereby reducing power consumption of the terminal. For example, when a pedometer application calls G-sensor (Gravity-sensor, acceleration sensor) data, it can set a larger dump (that is, set a larger buffer storage space) to reduce the buffer output data to the processor. times, thereby saving terminal power consumption.

When it is determined that the current terminal system is not in the dormant state, the target application that currently enables the target sensor may be determined, that is, the target application that currently invokes sensor data may be determined.

102. According to the frequency setting information of the target application, determine a target upload frequency required for the buffer corresponding to the target sensor to upload data to the processor.

Specifically, the target upload frequency required for the buffer corresponding to the target sensor to upload data to the processor can be determined according to the frequency requirement set by the target application. For example, the frequency setting information can be determined according to the parameters carried by the application itself.

Wherein, the frequency setting information may be a data upload frequency carried by the application program itself, and the like. The terminal may determine a target upload frequency that needs to be achieved by the buffer for uploading data to the processor according to the frequency setting information of the target application.

In this embodiment, the buffer may specifically be a FIFO (First In First Out) buffer, which includes multiple important parameters, such as the depth (THE DEEPTH) of the FIFO, the width (THE WIDTH) of the FIFO, and the full flag , empty flags, etc.

In some implementations, when some applications call sensor data, the depth information of the buffer can be directly adjusted to a preset value without identifying the frequency requirement of the application, so as to further reduce power consumption of the terminal. For non-preset applications, it is necessary to identify the frequency requirements; that is, after determining the target application that currently enables the target sensor, before determining the target upload frequency that the buffer corresponding to the target sensor uploads data to the processor. , the method can also include:

Determine whether the target application is a default application;

If not, a step of determining a target upload frequency required for the buffer corresponding to the target sensor to upload data to the processor is performed.

103 Judging whether the uploading frequency of the current buffer to upload data to the processor is equal to the target uploading frequency; if yes, end the process; if not, execute step 104 .

Specifically, the current upload frequency of data uploaded by the buffer to the processor may be obtained, and then the current upload frequency is compared with the target upload frequency to determine whether the current upload frequency is equal to the target upload frequency.

Wherein, the target upload frequency can be a frequency interval, for example, the frequency interval can be [a HZ, b HZ], if the current upload frequency is within this frequency interval, it can be determined that the upload frequency of the current buffer to upload data to the processor is equal to The target upload frequency, otherwise it is determined that the upload frequency of the current buffer to upload data to the processor is not equal to the target upload frequency.

104. Adjust the depth information of the buffer so that the upload frequency is equal to the target upload frequency.

Specifically, when it is determined that the current upload frequency of data uploaded by the buffer to the processor is not equal to the target upload frequency, the depth information of the buffer is adjusted so that the upload frequency is equal to the target upload frequency. Since the width of the FIFO is generally fixed and the depth of the FIFO is adjustable, the storage capacity of the FIFO can be changed by adjusting the depth information of the FIFO, and then the frequency of uploading data from the buffer to the processor can be adjusted.

In this embodiment, there may be multiple ways to adjust the depth information of the buffer. Optionally, the application level can be divided according to the frequency requirements of the application, and the corresponding relationship between the application level and the FIFO depth can be established, and the depth information of the buffer can be adjusted according to the application level; that is, the step "adjusting the depth information of the buffer" is specific The flow can be as follows:

Determine the application level of the target application according to the target upload frequency;

Adjust the depth information of the buffer according to the application level.

Specifically, there are many ways to determine the application level of the target application. For example, the target application with the target upload frequency in a certain frequency range can be divided into the same level of application level; that is, the step "determine the target application according to the target upload frequency "Application level of application" can specifically include:

Determine whether the target upload frequency is within the preset frequency range;

If yes, obtain the preset frequency level corresponding to the preset frequency range;

The application level of the target application is determined according to the preset frequency level.

Another option is that when other parameters of the buffer are constant, the depth of the FIFO is directly proportional to the storage capacity of the buffer and inversely proportional to the upload frequency. Therefore, the upload frequency can be compared with the target upload frequency, and the depth information can be adjusted according to the comparison result. For example, the depth information may include a depth value; the specific process of the step "adjusting the depth information of the buffer" may be as follows:

Determine whether the upload frequency is greater than the target upload frequency;

If so, increase the depth value of the buffer;

If not, decrease the depth value of the buffer.

Specifically, when the upload frequency is greater than the target upload frequency, the upload frequency is reduced by increasing the depth value of the buffer; when the upload frequency is lower than the target upload frequency, the upload frequency is increased by reducing the depth value of the buffer .

It can be seen from the above that the embodiment of the present invention provides a data transmission control method, by determining the target application that currently enables the target sensor, and then, according to the frequency setting information of the target application, determine the buffer corresponding to the target sensor to upload data to the processor The target upload frequency that needs to be achieved, and judge whether the upload frequency of the current buffer uploading data to the processor is equal to the target upload frequency, if not, adjust the depth information of the buffer so that the upload frequency is equal to the target upload frequency; this scheme can Adjust the depth information of the buffer according to the frequency requirements of different applications, so that the frequency of uploading the stored data to the processor meets the frequency requirements of the application. Compared with the existing technology, the data transmission rate can be effectively controlled and the terminal power consumption.

Embodiment two,

According to the method described in Embodiment 1, an example will be given below for further detailed description.

In this embodiment, a detailed description will be made by taking the data transmission control apparatus specifically integrated in a mobile terminal as an example.

As shown in Figure 2, a data transmission control method, the specific process may be as follows:

201. The mobile terminal determines a target application that currently enables a target sensor.

In some implementations, before the mobile terminal determines the target application that currently enables the target sensor, it can determine whether the current terminal system is in a dormant standby state, and if it is in a dormant state, then determine whether the current target sensor is enabled, that is, determine Whether the target sensor is working. If the target sensor is in the working state and the current system is in the dormant state, in order to reduce the power consumption of the terminal, the number of system wake-ups can be reduced; for example, the number of data transmissions to the processor can be reduced to reduce the number of wake-ups of the system.

Specifically, the data acquired by the sensor can be stored in the buffer, and the data can be transmitted to the processor when the buffer is full. Therefore, the storage space of the buffer can be adjusted to the maximum by adjusting the storage parameters of the buffer, such as depth information. , so as to reduce the frequency of uploading data from the buffer to the processor, thereby reducing power consumption of the terminal. For example, when a pedometer application calls the data of the G-sensor, a larger dump can be set to reduce the number of times the buffer outputs data to the processor, thereby saving power consumption of the mobile terminal.

202. The mobile terminal determines whether the target application is a preset application; if yes, execute step 206; if not, execute step 203.

In this embodiment, there are many ways to judge whether the target application is a preset application. For example, it can be judged whether there is a sample identifier matching the target application in the preset identifier set; that is, the step "judging whether the target application For preset applications" can specifically include:

Obtain the application identifier of the target application;

Judging whether there is a sample identifier matching the target application in the preset identifier set;

If it exists, it is determined that the target application is a default application;

If not, it is determined that the target application is not a preset application.

203. The mobile terminal determines, according to the frequency setting information of the target application, a target upload frequency that needs to be achieved by the buffer corresponding to the target sensor for uploading data to the processor.

Specifically, when it is determined that the target application is not a preset application, a target upload frequency that needs to be achieved when the buffer uploads data to the processor is determined according to the frequency setting information of the target application.

During specific implementation, the target upload frequency required for the buffer corresponding to the target sensor to upload data to the processor can be determined according to the frequency requirements set by the target application. For example, the frequency setting information can be determined according to the parameters carried by the application itself.

Wherein, the frequency setting information may be a data upload frequency carried by the application program itself, and the like. The terminal may determine a target upload frequency that needs to be achieved by the buffer for uploading data to the processor according to the frequency setting information of the target application.

In this embodiment, the buffer may specifically be a FIFO buffer, which includes multiple important parameters, such as FIFO depth, FIFO width, full flag, empty flag, and the like.

204. The mobile terminal judges whether the current upload frequency of data uploaded by the buffer to the processor is equal to the target upload frequency; if yes, end the process; if not, execute step 205.

Specifically, the current upload frequency of data uploaded by the buffer to the processor may be obtained, and then the current upload frequency is compared with the target upload frequency to determine whether the current upload frequency is equal to the target upload frequency.

Wherein, the target upload frequency can be a frequency interval, for example, the frequency interval can be [a HZ, b HZ], if the current upload frequency is within this frequency interval, it can be determined that the upload frequency of the current buffer to upload data to the processor is equal to The target upload frequency, otherwise it is determined that the upload frequency of the current buffer to upload data to the processor is not equal to the target upload frequency.

205. The mobile terminal adjusts the depth information of the buffer so that the upload frequency is equal to the target upload frequency.

Specifically, when it is determined that the current upload frequency of data uploaded by the buffer to the processor is not equal to the target upload frequency, the depth information of the buffer is adjusted so that the upload frequency is equal to the target upload frequency.

In this embodiment, there may be multiple ways to adjust the depth information of the buffer. Optionally, the application level can be divided according to the frequency requirements of the application, and the corresponding relationship between the application level and the FIFO depth can be established, and the depth information of the buffer can be adjusted according to the application level; that is, the step "adjusting the depth information of the buffer" is specific The flow can be as follows:

Determine the application level of the target application according to the target upload frequency;

Adjust the depth information of the buffer according to the application level.

Specifically, there are many ways to determine the application level of the target application. For example, the target application with the target upload frequency in a certain frequency range can be divided into the same level of application level; that is, the step "determine the target application according to the target upload frequency "Application level of application" can specifically include:

Determine whether the target upload frequency is within the preset frequency range;

If yes, obtain the preset frequency level corresponding to the preset frequency range;

The application level of the target application is determined according to the preset frequency level.

Another option is that when other parameters of the buffer remain unchanged, the depth of the FIFO is directly proportional to the storage capacity of the buffer and inversely proportional to the upload frequency. Therefore, the upload frequency can be compared with the target upload frequency, and the depth information can be adjusted according to the comparison result. For example, the depth information may include a depth value; the specific process of the step "adjusting the depth information of the buffer" may be as follows:

Determine whether the upload frequency is greater than the target upload frequency;

If so, increase the depth value of the buffer;

If not, decrease the depth value of the buffer.

Specifically, when the upload frequency is greater than the target upload frequency, the upload frequency is reduced by increasing the depth value of the buffer; when the upload frequency is lower than the target upload frequency, the upload frequency is increased by reducing the depth value of the buffer .

206. The mobile terminal adjusts the depth value of the buffer to the maximum value.

In some implementations, when some application calls sensor data, the depth value of the buffer can be directly adjusted to the maximum value without identifying the frequency requirement of the application, so as to further reduce the power consumption of the terminal. Taking step counting applications as an example, you can directly adjust the depth value of the buffer corresponding to the G-sensor to the maximum value to maximize the buffer dump space, reduce the frequency of outputting data from the cache to the processor, and further reduce the terminal power consumption.

It can be seen from the above that the embodiment of the present invention provides a data transmission control method, which determines the target application that currently enables the target sensor through the mobile terminal, and judges whether the target application is a preset application, and if not, sets the target application according to the frequency of the target application. Information, determine the target upload frequency that the buffer corresponding to the target sensor uploads data to the processor, and then judge whether the current upload frequency is equal to the target upload frequency, if not, adjust the depth information of the buffer so that the upload frequency is equal to Target upload frequency; this solution can adjust the depth information of the buffer according to the frequency requirements of different applications, so that the frequency of uploading the stored data to the processor meets the frequency requirements of the application. Compared with the existing technology, it can be effectively controlled The data transfer rate reduces the terminal power consumption.
