B2 when described file content is not empty content, stops to read file content corresponding to next file path.
Substep 2023 when reading successively, when file content corresponding to described any one file path reads failure, when the file content that perhaps described any one file path is corresponding is empty content, continues to read file content corresponding to next file path.
Below, be introduced as an example of Android system example, by analysis, in Android operating system, the path that is used for the file of storage battery temperature data can comprise following several:
(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 production firms, the operating system of terminal is different with the position of the file that temperature data writes, but the analysis found that, the position of temperature data storage is in file corresponding to a path in above-mentioned three file paths.Therefore, in the embodiment of the invention, can successively above-mentioned three file paths regularly be passed to the ReadInfo function, then (for example receive the rreturn value of ReadInfo function, can pass through the Shandong great master regularly to ReadInfo function passes file path), until under one of them file path, read corresponding file content.Detailed process can comprise:
Step 1, file path/sys/class/hwmon/hwmon0/device/temp1_input is passed to the ReadInfo function as parameter.
If the ReadInfo function successfully gets access to the file content under this document path, then execution in step 2; If file content obtains failure, then execution in step 4.
Step 2 judges whether described file content is empty.
If described file content is not empty, then execution in step 3; If described file content is empty, then execution in step 4.
Step 3, the rreturn value of reception ReadInfo function, described rreturn value is file content corresponding to described file path/sys/class/hwmon/hwmon0/device/temp1_input.
Step 4 passes to the ReadInfo function with file path/sys/class/power_supply/battery/temp as parameter.
If the ReadInfo function successfully gets access to the file content under this document path, if then execution in step 5 file contents obtain failure, then execution in step 7.
Step 5 judges whether described file content is empty.
If described file content is not empty, then execution in step 6; If described file content is empty, then execution in step 7.
Step 6, the rreturn value of reception ReadInfo function, described rreturn value is file content corresponding to described file path/sys/class/power_supply/battery/temp.
Step 7, file path/sys/class/power_supply/battery/batt_temp is passed to the ReadInfo function as parameter.
If the ReadInfo function successfully gets access to the file content under this document path, and described file content is not empty, and then execution in step 8.
Step 8, the rreturn value of reception ReadInfo function, described rreturn value is file content corresponding to described file path/sys/class/power_supply/battery/batt_temp.
Owing to can learn that through foregoing description above-mentioned three kinds of file paths are the path of the file of possible storage battery temperature data, therefore, in the embodiment of the invention, can read corresponding file content under the file path therein at least.Therefore, in said process, if under file path/sys/class/hwmon/hwmon0/device/temp1_input and file path/sys/class/power_supply/battery/temp, all do not read corresponding file content, then under file path/sys/class/power_supply/battery/batt_temp, can read corresponding file path.
Need to prove, the order that reads for above-mentioned three kinds of file paths in the embodiment of the invention is not limited.And, above-mentioned three kinds of file paths are for Android operating system, and still, the embodiment of the invention is not limited to above-mentioned three kinds of file paths, for example may be other file path for some other operating system, the embodiment of the invention is discussed no longer in detail to this.
Step 204 is extracted described battery temperature data from described file content.
In step 202, read after the corresponding file path, owing to storing the battery temperature data in the file content under this document path, therefore, in this step, namely can from the file content that reads, extract the battery temperature data.
In the embodiment of the invention, by above-mentioned steps 200-step 204 can Real-time Obtaining to the battery temperature data of terminal, so that obtaining of battery temperature data is more timely.
On the other hand, the analysis found that, when the battery status of terminal changed, the terminal operating system system can send broadcast event, had comprised the battery temperature data message of terminal in the additional data of this broadcast event.Therefore, the embodiment of the invention has also further proposed to obtain by this broadcast event the method for battery temperature data.
Concrete, the battery temperature monitoring method of the embodiment of the invention can also comprise:
In the embodiment of the invention, the state of described battery changes and can comprise following several situation:

Therefore, the embodiment of the invention is in order to address this problem, proposed by in the step 200-step 204 in real time the file content corresponding to file path of the battery temperature data place file that senses of reading temperature sensor obtain the method for battery temperature data.The method is at first determined the path that may store the file of battery temperature data in the terminal, then can read in real time the file content under these file paths, thereby can not be subjected to the restriction of battery status, when even battery status does not change, also be to get access to corresponding battery temperature data.Therefore, with respect to the above-mentioned method of obtaining the battery temperature data by reading broadcast event, this method that reads file content corresponding under the default file path can not be subjected to the restriction of external condition (state variation of battery), makes the renewal of battery temperature data more timely.
Because some terminals have singularity, the unit of the battery temperature data that these terminals get access to may not be ℃, therefore, for the span of the unified temperature that gets access to, the battery temperature data can be set all take ℃ as unit in the embodiment of the invention.
In the embodiment of the invention, can set in advance temperature range, when the battery temperature data that get access to are within this default temperature range, determine that this temperature is the battery temperature data of terminal.
Therefore, the described battery temperature data monitoring method of the embodiment of the invention can also may further comprise the steps:
Step 210 compares the battery temperature data of extracting and the temperature range of presetting.
Step 212 when described battery temperature data are within described temperature range, determines that described battery temperature data within temperature range are the battery temperature data of terminal.
In the embodiment of the invention, it is 15 ℃-60 ℃ that described temperature range can be set, if battery temperature data that extract within this temperature range the time, then could be with the battery temperature data of this temperature as terminal.
If the battery temperature data that extract have exceeded the said temperature scope, the embodiment of the invention can also further be processed the temperature that extracts, so that it is within the normal temperature range.
For example, if the battery temperature data that extract are 300 (its unit may not be ℃), then the embodiment of the invention can be with this numerical value divided by a fixed value (for example divided by 10).If divided by the numerical value after this fixed value also not within the said temperature scope, the numerical value that then can continue to obtain is divided by above-mentioned fixed value, until the numerical value that draws in described temperature range, is defined as described battery temperature data within temperature range the battery temperature data of terminal at last.
Need to prove, above-mentioned temperature range is for the purpose of illustration only, and the embodiment of the invention is not limited concrete numerical value.
The end cell temperature monitoring method of the embodiment of the invention not only can the analysing terminal battery in the file path of the battery temperature data place file that arrives of temperature sensor senses, and regular file reading content under the described file path, and therefrom extract the battery temperature data, can also obtain the battery temperature data by the broadcast event that system sends, thereby can obtain more timely and accurately the battery temperature data of terminal, solved thus owing to can't obtain current battery temperature data, cause battery temperature too high and affect the problem of terminal capabilities, obtained and to have read timely and accurately the battery temperature data, reduced the beneficial effect on the impact of terminal capabilities.
Need to prove, for aforesaid embodiment of the method, for simple description, therefore it all is expressed as a series of combination of actions, but those skilled in the art should know, the application is not subjected to the restriction of described sequence of movement, because according to the application, some step can adopt other orders or carry out simultaneously.Secondly, those skilled in the art also should know, the embodiment described in the instructions all belongs to preferred embodiment, and related action might not be that the application is necessary.
