Detailed ways

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 persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

The embodiment of the present invention provides a thermal protection method, as shown in Figure 1, including:

101. Acquire the measured temperature at each temperature measurement position through a temperature sensor disposed at at least one temperature measurement position of the device.

Specifically, a temperature sensor is provided at each temperature measurement position of the device, and the measured temperature at each temperature measurement position can be obtained through the temperature sensor.

It should be noted that the temperature measurement position refers to the position where the processing unit with high heat generation in the device is predetermined based on experience. There may be multiple temperature measuring positions in the device, and a temperature sensor is provided at each temperature measuring position.

For example, if the device is a mobile phone, the position of the modem processor on the printed circuit board of the mobile phone is the temperature measurement position, and a temperature sensor is set at this position; the position of the application processor on the printed circuit board of the mobile phone is the temperature measurement position , and a temperature sensor is set at this position; the radio frequency position of the mobile phone is the temperature measurement position, and a temperature sensor is set at this position. Through the temperature sensors at the three temperature measuring positions, the measured temperature at the position of the modem processor of the mobile phone, the measured temperature at the position of the application processor of the mobile phone, and the measured temperature at the position of the radio frequency of the mobile phone are obtained respectively.

Preferably, the temperature sensor is a thermistor.

102. Acquire preset temperatures at each of the temperature measurement positions.

It should be noted that when the temperature sensor is set at at least one temperature measuring position of the device, correspondingly, the preset temperature corresponding to the processing unit of the device at at least one temperature measuring position is also preset.

It should be noted that the preset temperature is a preset maximum temperature at which the processing unit of the device works normally. If the temperature of the processing unit of the device exceeds the preset temperature, it indicates that the temperature of the processing unit of the device is too high and needs to be cooled. The preset temperatures at each temperature measuring position may be the same or different, which is not limited in the present invention.

As described in the above example, the preset temperature at the modem processor of the mobile phone, the preset temperature at the application processor of the mobile phone, and the preset temperature at the radio frequency of the mobile phone are acquired respectively.

It should be noted that the sequence between steps 101 and 102 is not limited, and only one is shown in the figure.

103. Compare the measured temperature at each temperature measurement position with its corresponding preset temperature.

Specifically, after obtaining the measured temperature at each temperature measuring position and the preset temperature at each temperature measuring position, compare the measured temperature at each temperature measuring position with its corresponding preset temperature, so as to know the temperature of each temperature measuring position. Whether the measured temperature at the temperature position is normal temperature. If the measured temperature at each temperature measuring position does not exceed the corresponding preset temperature, it means that the measured temperature at each temperature measuring position is normal, and there is no need to cool down the processing unit at each temperature measuring position.

As in the above example, compare the measured temperature at the modem processor location of the mobile phone with the preset temperature at the modem processor location of the mobile phone, if the measured temperature at the modem processor location of the mobile phone does not exceed the If the preset temperature at the modem processor of the mobile phone is normal, it means that the temperature of the modem processor of the mobile phone is normal and there is no need to cool down. Comparing the measured temperature at the location of the application processor of the mobile phone with the preset temperature at the location of the application processor of the mobile phone, if the measured temperature at the location of the application processor of the mobile phone does not exceed the preset temperature at the location of the application processor of the mobile phone, then It means that the temperature of the application processor of the mobile phone is normal and there is no need to cool down. Compare the measured temperature of the radio frequency of the mobile phone with the preset temperature of the radio frequency of the mobile phone. If the measured temperature of the radio frequency of the mobile phone does not exceed the preset temperature of the radio frequency of the mobile phone, it means that the temperature of the radio frequency of the mobile phone is normal and there is no need to cool down deal with.

104. If a first measured temperature at a first temperature measurement location exceeds its corresponding preset temperature, determine an abnormal temperature level of the first measured temperature.

It should be noted that the first temperature measurement position refers to a temperature measurement position where the measured temperature exceeds its corresponding preset temperature, so the measured temperature acquired at the first temperature measurement position is called the first measurement temperature.

Specifically, when comparing the measured temperature at each temperature measuring position with its corresponding preset temperature, according to the comparison result between the measured temperature at each temperature measuring position and its corresponding preset temperature, it is determined in sequence If there is a first measured temperature at the first temperature measurement position exceeding its corresponding preset temperature among the temperature measurement temperatures at each temperature measurement position, then determine the abnormal temperature level of each first measurement temperature.

Further, if the first measured temperature at no first temperature measurement position exceeds its corresponding preset temperature, it means that the temperature measurement at each temperature measurement position is normal, and no cooling measures need to be taken.

As mentioned in the above example, if the measured temperature at the position of the modem processor of the mobile phone exceeds the corresponding preset temperature, and the measured temperature at the position of the application processor of the mobile phone does not exceed the corresponding preset temperature, the radio frequency position of the mobile phone If the measured temperature exceeds the corresponding preset temperature, the position of the modem processor of the mobile phone is the first temperature measurement position, the measured temperature at the position of the modem processor of the mobile phone is the first measurement temperature, and the radio frequency position of the mobile phone It is also the first temperature measuring position, and the measured temperature at the radio frequency position of the mobile phone is also the first measured temperature. Determine the abnormal temperature level of the first measured temperature, that is, determine the abnormal temperature level of the measured temperature at the modem processor position of the mobile phone, and determine the abnormal temperature level of the measured temperature at the radio frequency position of the mobile phone.

It should be noted that the abnormal temperature level is preset for each temperature measurement position. An abnormal temperature level corresponds to a temperature range and corresponds to a treatment measure for reducing power consumption. The higher the abnormal temperature level, the higher the temperature in the corresponding temperature range.

105. If the first measured temperature belongs to the first abnormal temperature level, perform a processing measure of reducing a performance parameter of a processing unit of the device located at the first temperature measurement position.

Wherein, the performance parameter is a parameter related to the power consumption of the device. And the performance parameter of the processing unit includes: the main frequency or the transmission power of the processing unit.

Specifically, if the first measured temperature is within the temperature range corresponding to the first abnormal temperature level among the abnormal temperature levels corresponding to the first temperature measurement position, then the first measured temperature belongs to the first abnormal temperature level, and the first abnormal temperature level is executed. The processing measure corresponding to the temperature level to reduce the performance parameter of the processing unit of the device at the first temperature measurement position. For example, reduce the main frequency of the processing unit or reduce the transmission power of the processing unit.

As described in the above example, if the measured temperature at the position of the modem processor of the mobile phone belongs to the temperature range of the first abnormal temperature level of the abnormal temperature level corresponding to the modem processor of the mobile phone, then according to the temperature range corresponding to the first abnormal temperature level The processing measures are to reduce the main frequency of the modem processor of the mobile phone, thereby reducing the power consumption of the modem processor of the mobile phone, and reducing the temperature of the modem processor of the mobile phone.

An embodiment of the present invention provides a thermal protection method. The temperature sensor is used to obtain each measurement temperature of the device at at least one temperature measurement position, and obtain the preset temperature at each temperature measurement position, and compare each measurement temperature with its corresponding preset temperature. Set temperature for comparison. If the first measured temperature at the first temperature measurement position exceeds its corresponding preset temperature, determine the abnormal temperature level of the first measured temperature; The performance parameters of the processing unit at the temperature position are used to reduce the power consumption of the device, thereby reducing the temperature of the device, thereby avoiding the excessive temperature of the device under continuous use conditions and improving the user experience.

The above method, as shown in Figure 2, also includes:

106. If the first measured temperature belongs to the second abnormal temperature level, perform a processing measure of feeding back information that the temperature of the processing unit at the first temperature measurement position is too high.

Specifically, if the first measured temperature is within the temperature range corresponding to the second abnormal temperature level among the abnormal temperature levels corresponding to the first temperature measurement position, then the first measured temperature belongs to the second abnormal temperature level, and the second abnormal temperature level is executed. The treatment measures corresponding to the temperature level are to feed back the information that the temperature of the processing unit at the first temperature measurement position is too high, so that the user can know that the temperature of the device is too high through the feedback information, and take measures to reduce the temperature of the processing unit at the first temperature measurement position. Temperature measures, such as shutting down the device or stopping running related applications, etc.

As mentioned in the above example, if the measured temperature at the radio frequency of the mobile phone belongs to the temperature range of the second abnormal temperature level of the abnormal temperature level corresponding to the radio frequency of the mobile phone, then the processing measures corresponding to the second abnormal temperature level are executed, that is, to the mobile phone user Feedback the information that the temperature at the radio frequency position of the mobile phone is too high, so that the mobile phone user knows that the temperature at the radio frequency position of the mobile phone is too high, and take relevant measures to reduce the temperature at the radio frequency position of the mobile phone, such as receiving calls and other measures.

The above method, shown in FIG. 2 with reference, also includes:

107. If the first measured temperature belongs to the third abnormal temperature level, perform a processing measure of closing all running application programs of the processing unit at the first temperature measurement location.

Specifically, if the first measured temperature is within the temperature range corresponding to the third abnormal temperature level among the abnormal temperature levels corresponding to the first temperature measurement position, then the first measured temperature belongs to the third abnormal temperature level, and the third abnormal temperature level is executed. The processing measure corresponding to the temperature level is to close all running applications of the processing unit at the first temperature measurement location. For example, the processing unit at the first temperature measurement position is running the local game and media player, and at this time, close the application programs related to the local game and media player.

The above method, shown in FIG. 2 with reference, also includes:

108. If the first measured temperature belongs to the fourth abnormal temperature level, perform a processing measure of shutting down the device.

Specifically, if the first measured temperature is within the temperature range corresponding to the fourth abnormal temperature level among the abnormal temperature levels corresponding to the first temperature measurement position, then the first measured temperature belongs to the fourth abnormal temperature level, and the fourth abnormal temperature level is executed. The treatment measure corresponding to the temperature level is to shut down the device.

After steps 106-108, according to the level of the first measurement temperature at the first temperature measurement position of the device, different measures to reduce power consumption are taken to reduce the temperature at the first temperature measurement position, so as to avoid the overheating of the device under continuous use conditions. High temperature improves user experience.

The above method, as shown in Figure 3, after step 105, also includes:

109. Obtain a second measured temperature at the first temperature measurement position through the temperature sensor at the first temperature measurement position.

Specifically, after reducing the performance parameter of the processing unit of the device located at the first temperature measurement position, the second measurement temperature at the first temperature measurement position is obtained through the temperature sensor at the first temperature measurement position.

As described in the above example, after the main frequency of the modem processor of the mobile phone is reduced, the second measured temperature at the position of the modem processor of the mobile phone is acquired through the temperature sensor at the position of the modem processor of the mobile phone.

110. If the second measured temperature does not exceed the preset temperature at the first temperature measurement position, restore the performance parameter of the processing unit of the device at the first temperature measurement position to an original value.

Specifically, if the second measured temperature does not exceed the preset temperature at the first temperature measurement position, it means that the temperature of the processing unit at the first temperature measurement position of the device has dropped, and at this time, the device at the first temperature measurement position is lowered. The performance parameter of the processing unit at the temperature measurement position is restored to the original value.

Further, if the second measured temperature exceeds the preset temperature at the first temperature measurement position, then determine the abnormal temperature level of the second measured temperature.

If the second measured temperature belongs to the first abnormal temperature level, then detect whether the performance parameter of the processing unit at the first temperature measurement position of the equipment reaches the minimum value, if not, further reduce the temperature of the equipment at the first temperature measurement position The performance parameters of the processing unit. If the minimum value is reached, the performance parameter of the processing unit at the first temperature measurement position of the device is not reduced, that is, no processing is performed on the performance parameter of the processing unit of the device at the first temperature measurement position at this time. If the second measured temperature belongs to the second abnormal temperature level, feeding back the information that the temperature of the processing unit at the first temperature measurement position is too high. If the second measured temperature belongs to the third abnormal temperature level, all the running applications of the processing unit at the first temperature measurement location are closed. If the second measured temperature belongs to the fourth abnormal temperature level, shutting down the device.

It should be noted that the minimum value of the performance parameter of the processing unit located at the temperature measurement position of the device is preset.

Optionally, the above method, as shown in FIG. 4, after step 102 and before step 103, further includes:

111. Sort the measured temperatures at the various temperature measurement positions.

As described in the above example, after obtaining the measured temperature at the position of the modem processor of the mobile phone, the measured temperature at the position of the application processor of the mobile phone, and the measured temperature at the position of the radio frequency of the mobile phone, the above three measured temperatures are obtained from Sort from high to low.

Step 103 comparing the measured temperature at each temperature measuring position with its corresponding preset temperature includes: sequentially comparing the measured temperatures at each temperature measuring position from high to low The measured temperature and its corresponding preset temperature.

Specifically, according to the sorting of the measured temperatures at each temperature measuring position from high to low, first compare the measured temperature at the temperature measuring position with the highest temperature in the sorting with its corresponding preset temperature, if the temperature measuring position with the highest temperature in the sorting If the measured temperature at the temperature position does not exceed its corresponding preset temperature, then continue to compare the measured temperature at the next temperature measurement position in the sequence with its corresponding preset temperature. If the measured temperature at the temperature measuring position with the highest temperature in the sorting exceeds its corresponding preset temperature, then determine the abnormal temperature level corresponding to the measured temperature at the temperature measuring position with the highest temperature in the sorting, and determine the After determining the abnormal temperature level corresponding to the measured temperature at the temperature measuring position with the highest temperature in the above sorting, take corresponding measures to reduce power consumption. Then, continue to compare the measured temperature at the next temperature measuring position in the sequence with its corresponding preset temperature until the measured temperature at the last temperature measuring position in the sequence is compared with its corresponding preset temperature.

As mentioned in the above example, the measured temperature at the position of the modem processor of the mobile phone, the measured temperature at the position of the application processor of the mobile phone and the measured temperature at the position of the radio frequency of the mobile phone are sorted from high to low: at the radio frequency position of the mobile phone The measured temperature at the location of the modem processor of the phone, the measured temperature at the location of the application processor of the phone.

First, compare the measured temperature at the radio frequency position of the mobile phone with the highest temperature in the sorting with its corresponding preset temperature, if the measured temperature at the radio frequency position of the mobile phone with the highest temperature exceeds its corresponding preset temperature, determine the radio frequency of the mobile phone If the abnormal temperature level of the measured temperature at the position is the second abnormal temperature level, the corresponding processing measures for the second abnormal temperature level are executed, that is, the information that the temperature at the radio frequency position of the mobile phone is too high is fed back. Then, continue to compare the measured temperature at the modem processor position of the mobile phone with its corresponding preset temperature, if the measured temperature at the modem processor position of the mobile phone exceeds its corresponding preset temperature, then determine the temperature of the mobile phone If the abnormal temperature level of the measured temperature at the position of the modem processor is the first abnormal temperature level, then reduce the main frequency of the modem processor of the mobile phone. Continue to compare the measured temperature at the location of the mobile phone's application processor with its corresponding preset temperature. If the measured temperature at the location of the mobile phone's application processor does not exceed its corresponding preset temperature, then compare the temperature at the next temperature measurement location in the sequence. The measured temperature and its corresponding preset temperature. Since the measured temperature at the location of the application processor of the mobile phone is the measured temperature at the last temperature measurement location in the sorting, this process ends.

The above method, as shown in Figure 5, after step 104, also includes:

112. If the first measured temperatures at at least two first temperature measurement positions exceed their corresponding preset temperatures, sort the abnormal temperature levels of the at least two first measured temperatures.

Specifically, if the abnormal temperature levels of the at least two first measured temperatures are the same abnormal temperature level, sorting is performed according to the difference between each first measured temperature and its corresponding preset temperature. Optionally, The abnormal temperature levels of the at least two first measured temperatures are sorted according to the descending order of the difference between each first measured temperature and its corresponding preset temperature. If there are different abnormal temperature levels in the abnormal temperature levels of the at least two first measured temperatures, the abnormal temperature of each first temperature measured temperature is adjusted according to the abnormal temperature level of each first temperature measured temperature. Ranks are sorted.

113. According to the order of the abnormal temperature levels from high to low, sequentially execute the processing measures corresponding to the abnormal temperature levels of the processing units at the first temperature measurement positions corresponding to the at least two first measurement temperatures.

Specifically, according to the ordering of abnormal temperature levels, the processing measures corresponding to the abnormal temperature level of the processing unit at the first temperature measurement position corresponding to the highest abnormal temperature level are firstly executed. For example, if the highest abnormal temperature level is the third abnormal temperature level, then execute the processing measures corresponding to the third abnormal temperature level of the processing unit at the first temperature measurement position corresponding to the third abnormal temperature level, that is, turn off the third abnormal temperature level. All application processes that are running on the processing unit at a thermometric location. Then, execute the processing measures corresponding to the abnormal temperature level of the processing unit at the first temperature measuring position corresponding to the next abnormal temperature level in the sorting, until the processing at the first temperature measuring position corresponding to the last abnormal temperature level in the sorting The processing measures corresponding to the abnormal temperature level of the unit are executed.

As mentioned in the above example, there are two first temperature measurement positions where the first measured temperature exceeds its corresponding preset temperature, that is, the measured temperature at the position of the modem processor of the mobile phone exceeds its preset temperature, and the radio frequency of the mobile phone The measured temperature at the location exceeds the preset temperature of the device. If it is determined that the abnormal temperature level of the measured temperature at the position of the modem processor of the mobile phone is the first abnormal temperature level, and the abnormal temperature level of the measured temperature at the radio frequency position is the second abnormal temperature level, then the two abnormal temperatures Ranks are sorted from highest to lowest. According to the ordering of abnormal temperature levels from high to low, the processing measures corresponding to the second abnormal temperature level at the radio frequency position of the mobile phone are firstly executed, and the processing measures corresponding to the first abnormal temperature level at the mobile phone modem processor are executed.

It should be noted that if there is only one first measurement temperature at the first temperature measurement position exceeding its corresponding preset temperature, then the processing measures corresponding to the abnormal temperature level of the first measurement temperature at the first temperature measurement position will be executed .

It should be noted that steps 105-108 specifically illustrate different processing measures corresponding to different abnormal temperature levels.
