Referring to FIG. 1 , it shows a flow chart of a method for monitoring the temperature of a terminal battery proposed in an embodiment of the present invention. The method may specifically include:

Step 100, analyzing the file path of the file where the battery temperature data sensed by the temperature sensor in the battery of the terminal is located.

Wherein, the battery temperature data is the data that the system pre-calls the driver to notify the operating system to write into the file.

With the development of the Internet, more and more users choose smart mobile terminals. The current smart mobile terminals are developing rapidly. In order to support stronger performance and larger screens, terminals are generally equipped with batteries with larger capacity. The battery generates heat during use, and if the temperature of the battery is too high, it will affect the performance of the terminal.

Therefore, an embodiment of the present invention proposes a terminal battery temperature monitoring method, which can directly obtain battery temperature data by reading data from a terminal internal temperature sensor. Some temperature sensors are installed inside the terminal. These temperature sensors can monitor the temperature data of the internal equipment of the terminal in real time. The device driver implemented by the manufacturer can obtain specific temperature data from the temperature sensor, and then the system calls the driver in advance to notify the operating system. Then the operating system writes these temperature data into corresponding files.

In the embodiment of the present invention, first of all, by analyzing the underlying source code of the terminal system, it is possible to find out which file the temperature sensor data in the terminal battery is stored in and what the file path is. After finding the file path, these files can be subsequently The content of the file under the path is processed.

Step 102, read the content of the file corresponding to the file path.

In step 100, analyze the file path of the file where the battery temperature data sensed by the temperature sensor in the battery of the terminal is located, because the file under the file path is a file that stores battery temperature data determined after analyzing the terminal , therefore, after the above file path is obtained, the file content corresponding to the file path can be read.

Wherein, the file content includes battery temperature data, and may also include some other information, which is not limited in this embodiment of the present invention.

Step 104, extracting the battery temperature data from the file content.

After reading the file content corresponding to the file path, the battery temperature data can be directly extracted from the file content.

If the current battery temperature is too high, some measures can be taken to reduce the battery temperature (for example, if the current game is being played, the current game can be stopped).

The specific process of the above steps will be described in detail in the following embodiments.

The terminal battery temperature monitoring method proposed in the embodiment of the present invention can analyze the file path of the file where the battery temperature data sensed by the temperature sensor in the terminal battery is located, and read the file content corresponding to the file path. These file paths are passed to the system The file path of the file corresponding to the temperature sensor data is obtained from the analysis of the underlying source code, so the battery temperature data of the terminal can be directly extracted from the content of the file. This solves the problem that the battery temperature is too high and affects the performance of the terminal due to the inability to obtain the current battery temperature data, and can read the battery temperature data in a timely and accurate manner, reducing the impact on the terminal performance.

In the following, the method for monitoring the temperature of the terminal battery proposed in the embodiment of the present invention will be introduced in detail.

Referring to FIG. 2 , it shows a flow chart of a method for monitoring terminal battery temperature according to a specific embodiment of the present invention. The method may include:

Step 200, analyzing the file path of the file where the battery temperature data sensed by the temperature sensor in the battery of the terminal is located.

According to the relevant description of the first embodiment above, in the embodiment of the present invention, the path of the file storing the temperature sensor data in the battery of the terminal can be determined first by analyzing the underlying source code of the terminal system. After finding the path of the file, the follow-up can The contents of files under these file paths are processed.

As for the specific analysis process, those skilled in the art can perform corresponding processing according to the actual situation, and the embodiments of the present invention will not be discussed in detail here.

Wherein, the battery temperature data is the data that the system pre-calls the driver to notify the operating system to write into the file.

Considering that the manufacturers of each terminal may be different, and the location of the file where the operating system of different manufacturers write the temperature data is different, so the path of the file used to store the battery temperature data may also be different, so you can separately Terminals produced by different manufacturers are analyzed to obtain the paths of files used to store battery temperature data for different terminals.

Therefore, in the embodiment of the present invention, the file path of the file where the battery temperature data sensed by the temperature sensor is located may include multiple file paths.

Step 202, read the content of the file corresponding to the file path.

After determining the path of the file used to store the battery temperature data in the terminal, since the battery temperature data of the terminal is stored in the file content under these file paths, the file content corresponding to the file path can be read through the system .

In the embodiment of the present invention, a timer can be set, and the system can be regularly notified through the timer to read the file content directly from the file path. The embodiment of the present invention does not limit the time interval for reading.

According to the relevant description of the above step 200, it can be known that the file path of the file where the temperature sensor data is located in the embodiment of the present invention may include multiple file paths. Therefore, this step 202 may specifically include:

Sub-step 2021, sequentially read the corresponding file content from the multiple file paths.

In the embodiment of the present invention, for terminals of different manufacturers, the files storing the battery temperature data may be different, so a plurality of different file paths can be obtained after analysis. For a certain terminal, its battery temperature data will be stored in these files A file path in the path corresponds to a file in the path. Therefore, in the embodiment of the present invention, when reading the corresponding file content from the multiple file paths, the multiple file paths can be sequentially traversed and read according to the preset order until reading from one of the file paths to the corresponding file content.

For example, firstly, for the current terminal, the possibility of including the battery temperature data in the file content under each file path can be analyzed, and then the multiple file paths are sorted according to the possibility, and finally the sorted files are read sequentially. following file path.

Of course, some other characteristics of the file path can also be used for sorting, which is not limited in this embodiment of the present invention.

In the embodiment of the present invention, the corresponding file content can be read from the plurality of file paths through an information reading function (ReadInfo function).

This sub-step 2021 may include:

a1, calling the ReadInfo function, and sequentially passing the multiple file paths as parameters to the ReadInfo function.

a2. Receive the return value of the ReadInfo function, where the return value is the file content corresponding to the file path.

Wherein, the ReadInfo function is an information reading function of the operating system. For the specific process of reading the file content through the system function, those skilled in the art can perform corresponding processing according to the actual situation, and the embodiments of the present invention will not be discussed in detail here.

Sub-step 2022, when reading sequentially, when the file content is read from any file path, stop reading the file content corresponding to the next file path.

For different terminals, the path of the file storing the battery temperature data may be different. After analysis, these possible file paths are taken as the file path of the file where the battery temperature data sensed by the temperature sensor is located. When processing a terminal, if the file content is read from one of the file paths, it means that the file under the file path is the file used to store the battery temperature data in the terminal. At this time, you can no longer target Other paths read their file contents.

In the embodiment of the present invention, the sub-step 2022 may include:

b1, when the file content corresponding to any one file path is read successfully, judge whether the file content corresponding to any one file path is empty content.

b2, when the content of the file is not empty, stop reading the content of the file corresponding to the next file path.

Sub-step 2023, when reading sequentially, when the reading of the file content corresponding to any one of the file paths fails, or when the content of the file corresponding to any one of the file paths is empty, continue to read the file corresponding to the next file path content.

In the following, the Android system is taken as an example. After analysis, in the Android operating system, the path of the file used to store the battery temperature data may include the following:

(1) /sys/class/hwmon/hwmon0/device/temp1_input

(2)/sys/class/power_supply/battery/temp

(3)/sys/class/power_supply/battery/batt_temp

For different manufacturers, the location of the file where the operating system of the terminal writes the temperature data is different, but after analysis, it is found that the temperature data is stored in the file corresponding to one of the above three file paths. Therefore, in the embodiment of the present invention, the above three file paths can be regularly passed to the ReadInfo function in turn, and then the return value of the ReadInfo function can be received (for example, the file path can be passed to the ReadInfo function regularly through Master Lu), until one of the files Path to read the corresponding file content. Specific procedures can include:

Step 1. Pass the file path /sys/class/hwmon/hwmon0/device/temp1_input as a parameter to the ReadInfo function.

If the ReadInfo function successfully obtains the content of the file under the file path, perform step 2; if the acquisition of the file content fails, perform step 4.

Step 2, judging whether the content of the file is empty.

If the content of the file is not empty, execute step 3; if the content of the file is empty, execute step 4.

Step 3: Receive the return value of the ReadInfo function, and the return value is the file content corresponding to the file path /sys/class/hwmon/hwmon0/device/temp1_input.

Step 4, pass the file path /sys/class/power_supply/battery/temp as a parameter to the ReadInfo function.

If the ReadInfo function successfully obtains the file content under the file path, perform step 5; if the file content acquisition fails, perform step 7.

Step 5, judging whether the content of the file is empty.

If the file content is not empty, execute step 6; if the file content is empty, execute step 7.

Step 6: Receive the return value of the ReadInfo function, and the return value is the file content corresponding to the file path /sys/class/power_supply/battery/temp.

Step 7. Pass the file path /sys/class/power_supply/battery/batt_temp as a parameter to the ReadInfo function.

If the ReadInfo function successfully obtains the file content under the file path, and the file content is not empty, step 8 is performed.

Step 8: Receive the return value of the ReadInfo function, and the return value is the file content corresponding to the file path /sys/class/power_supply/battery/batt_temp.

From the above description, it can be known that the above three file paths are paths of files that may store battery temperature data, therefore, in the embodiment of the present invention, at least one of the file paths can read the corresponding file content. Therefore, in the above process, if the corresponding file content is not read under the file path /sys/class/hwmon/hwmon0/device/temp1_input and the file path /sys/class/power_supply/battery/temp, then in the file The corresponding file path can be read under the path /sys/class/power_supply/battery/batt_temp.

It should be noted that, in the embodiment of the present invention, there is no limitation on the reading order of the above three file paths. Moreover, the above three file paths are for the Android operating system, but the embodiment of the present invention is not limited to the above three file paths, for example, it may be other file paths for some other operating systems. This will not be discussed in detail.

Step 204, extracting the battery temperature data from the file content.

After the corresponding file path is read in step 202, since the battery temperature data is stored in the file content under the file path, the battery temperature data can be extracted from the read file content in this step.

In the embodiment of the present invention, the battery temperature data of the terminal can be obtained in real time through the above steps 200 to 204, so that the battery temperature data can be obtained more timely.

On the other hand, after analysis, it is found that when the battery status of the terminal changes, the terminal operating system system will send a broadcast event, and the additional data of the broadcast event includes the battery temperature data information of the terminal. Therefore, the embodiment of the present invention further proposes a method for acquiring battery temperature data through the broadcast event.

Specifically, the battery temperature monitoring method in the embodiment of the present invention may further include:

Step 206, when it is detected that the state of the battery changes, monitor the broadcast event sent by the terminal operating system.

In the embodiment of the present invention, the state of the battery changes may include the following situations:

Charging starts (for example, it is detected that the charger is plugged in), charging is completed (for example, it is detected that the charger is pulled out), or the change in battery power reaches a preset threshold (for example, the change in battery power reaches 1% or other values).

Certainly, the change of the battery state described in the embodiment of the present invention is not limited to the above situations, and may also include other situations, which are not limited in the embodiment of the present invention.

Step 208, read the additional data of the broadcast event, and extract battery temperature data from the additional data.

The above-mentioned broadcast event sent by the operating system contains additional data, and these additional data include the battery temperature data of the terminal, and the battery temperature data can also be obtained by the above-mentioned method of reading the corresponding file content under the preset file path For the specific process of battery temperature data, this embodiment of the present invention will not discuss in detail here.

After the terminal operating system sends out the broadcast event, it can read the additional data of the broadcast event, and extract the battery temperature data therein from the read additional data.

It should be noted that the above step 206 to step 208 is a process of obtaining battery temperature data by reading broadcast events of the operating system. However, the terminal operating system will only send the broadcast event when it detects that the state of the battery changes, that is, if the above method of reading broadcast events is used, the corresponding battery temperature data can only be obtained when the battery state changes, In the rest of the time, even if the battery temperature data changes, the corresponding battery temperature data cannot be obtained. Therefore, there is a problem that the battery temperature data is not updated in time in the manner of acquiring the battery temperature data by reading broadcast events.

Therefore, in order to solve this problem, the embodiment of the present invention proposes a method of acquiring battery temperature data by reading the file content corresponding to the file path of the file where the battery temperature data sensed by the temperature sensor is located in real time in steps 200-204. This method firstly determines the paths of files that may store battery temperature data in the terminal, and then can read the contents of files under these file paths in real time, so that it is not limited by the state of the battery, even if the state of the battery does not change. The corresponding battery temperature data can be obtained. Therefore, compared to the above-mentioned method of obtaining battery temperature data by reading broadcast events, the method of reading the corresponding file content under the preset file path may not be limited by external conditions (changes in the state of the battery), so that the battery temperature data Updates are more timely.

Due to the particularity of some terminals, the unit of the battery temperature data obtained by these terminals may not be °C. Therefore, in order to unify the value range of the obtained temperature, in the embodiment of the present invention, the unit of the battery temperature data can be set to be °C.

In the embodiment of the present invention, a temperature range may be preset, and when the acquired battery temperature data is within the preset temperature range, the temperature is determined to be the battery temperature data of the terminal.

Therefore, the battery temperature data monitoring method described in the embodiment of the present invention may further include the following steps:

Step 210, comparing the extracted battery temperature data with a preset temperature range.

Step 212, when the battery temperature data is within the temperature range, determine that the battery temperature data within the temperature range is the battery temperature data of the terminal.

In the embodiment of the present invention, the temperature range can be set to 15°C-60°C, and if the extracted battery temperature data is within the temperature range, the temperature can be used as the battery temperature data of the terminal.

Step 214, when the battery temperature data exceeds the temperature range, convert the battery temperature data into a temperature within the temperature range, and use the converted battery temperature data as the battery temperature data of the terminal.

If the extracted battery temperature data exceeds the above temperature range, the embodiment of the present invention may further process the extracted temperature to make it within a normal temperature range.

For example, if the extracted battery temperature data is 300 (the unit may not be °C), the embodiment of the present invention may divide this value by a fixed value (for example, by 10). If the value after dividing by the fixed value is not within the above temperature range, you can continue to divide the obtained value by the above fixed value until the obtained value is within the temperature range, and finally put the value in the temperature range The battery temperature data within is determined as the battery temperature data of the terminal.

It should be noted that the above-mentioned temperature range is only for example, and the embodiment of the present invention does not limit specific values.

The terminal battery temperature monitoring method of the embodiment of the present invention can not only analyze the file path of the file where the battery temperature data sensed by the temperature sensor in the terminal battery is located, but also regularly read the file content from the file path, and extract the battery temperature data from it , the battery temperature data can also be obtained through the broadcast event sent by the system, so that the battery temperature data of the terminal can be obtained more timely and accurately, thus solving the problem that the battery temperature is too high and affects the terminal performance due to the inability to obtain the current battery temperature data problem, the beneficial effect of being able to read battery temperature data in a timely and accurate manner and reducing the impact on terminal performance has been achieved.

It should be noted that, for the foregoing method embodiments, for the sake of simple description, they are expressed as a series of action combinations, but those skilled in the art should know that the present application is not limited by the described action sequence, because Depending on the application, certain steps may be performed in other orders or simultaneously. Secondly, those skilled in the art should also know that the embodiments described in the specification belong to preferred embodiments, and the actions involved are not necessarily required by this application.
