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.
An embodiment of the present invention provides a method for thermal protection, as shown in fig. 1, including:
101. and acquiring the measured temperature of each temperature measuring position through a temperature sensor arranged at least one temperature measuring position of the equipment.
Specifically, a temperature sensor is arranged at each temperature measuring position of the equipment, and the temperature sensor can acquire the measured temperature at each temperature measuring position.
The temperature measurement position is a position where a processing unit having high heat generation is located in the device, which is determined in advance by experience. The temperature measuring position in the equipment can be a plurality of, and each temperature measuring position is provided with a temperature sensor.
For example, the device is a mobile phone, the position of the modem processor of the printed circuit board of the mobile phone is a temperature measurement position, and a temperature sensor is arranged at the position; the position of an application processor of a printed circuit board of the mobile phone is a temperature measuring position, and a temperature sensor is arranged at the position; the radio frequency position of the mobile phone is a temperature measuring position, and a temperature sensor is arranged at the position. The temperature sensors at the three temperature measuring positions are used for respectively acquiring the measured temperature at the position of the modulation and demodulation 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 radio frequency position of the mobile phone.
Preferably, the temperature sensor is a thermistor.
102. And acquiring the preset temperature of each temperature measuring position.
It should be noted that, when the temperature sensor is disposed at least one temperature measurement position of the device, correspondingly, a preset temperature corresponding to the processing unit of the device at the at least one temperature measurement 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 normally operates. If the temperature of the processing unit of the equipment exceeds the preset temperature, the temperature of the processing unit of the equipment is too high, and the temperature needs to be reduced. The preset temperatures at the temperature measuring positions may be the same or different, and the present invention is not limited thereto.
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 rf of the mobile phone are obtained.
The sequence between steps 101 and 102 is not limited, and only one is shown in the figure.
103. And comparing the measured temperature at each temperature measuring position with the corresponding preset temperature.
Specifically, after the measured temperature at each temperature measurement position and the preset temperature at each temperature measurement position are obtained, the measured temperature at each temperature measurement position is compared with the corresponding preset temperature, so that whether the measured temperature at each temperature measurement position is normal or not is known. If the measured temperature at each temperature measuring position does not exceed the corresponding preset temperature, the measured temperature at each temperature measuring position is normal, and the processing unit at each temperature measuring position does not need to be cooled.
As described in the above example, the measured temperature at the position of the modem processor of the mobile phone is compared with the preset temperature at the position of the modem processor of the mobile phone, and if the measured temperature at the position of the modem processor of the mobile phone does not exceed the preset temperature at the position of the modem processor of the mobile phone, it indicates that the temperature of the modem processor of the mobile phone is normal, and the temperature reduction process is not needed. And comparing the measured temperature at the position of the application processor of the mobile phone with the preset temperature at the position of the application processor of the mobile phone, and if the measured temperature at the position of the application processor of the mobile phone does not exceed the preset temperature at the position of the application processor of the mobile phone, indicating that the temperature of the application processor of the mobile phone is normal and the temperature reduction treatment is not needed. And comparing the measured temperature at the radio frequency of the mobile phone with the preset temperature at the radio frequency of the mobile phone, and if the measured temperature at the radio frequency of the mobile phone does not exceed the preset temperature at the radio frequency of the mobile phone, indicating that the radio frequency of the mobile phone is normal without cooling treatment.
104. And if the first measured temperature at the first temperature measuring position exceeds the corresponding preset temperature, determining the abnormal temperature grade of the first measured temperature.
It should be noted that the first temperature measurement position is a temperature measurement position at which the measured temperature exceeds the corresponding preset temperature, so that the measured temperature obtained at the first temperature measurement position is referred to as a first measured temperature.
Specifically, when the measured temperature at each temperature measuring position is compared with the corresponding preset temperature, according to the comparison result between the measured temperature at each temperature measuring position and the corresponding preset temperature, if the first measured temperature at the first temperature measuring position exceeds the corresponding preset temperature in the temperature measuring temperatures at each temperature measuring position, the abnormal temperature grade of each first measured temperature is determined.
Further, if the first measured temperature at the first temperature measuring position does not exceed the corresponding preset temperature, it is indicated that the temperature measuring temperature at each temperature measuring position is normal, and no cooling measure is required.
As described in the above example, if the measured temperature at the position of the modem processor of the mobile phone exceeds the corresponding preset temperature, the measured temperature at the position of the application processor of the mobile phone does not exceed the corresponding preset temperature, and the measured temperature at the position of the radio frequency of the mobile phone 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 measured temperature, the radio frequency position of the mobile phone is also the first temperature measurement position, and the measured temperature at the position of the radio frequency of the mobile phone is also the first measured temperature. An abnormal temperature level for the first measured temperature is determined, that is, an abnormal temperature level for the measured temperature at the modem processor location of the handset is determined, and an abnormal temperature level for the measured temperature at the radio frequency location of the handset is determined.
Note that an abnormal temperature level is set in advance for each temperature measurement position. An abnormal temperature level corresponds to a temperature range and to a processing measure for reducing power consumption, and the higher the abnormal temperature level is, the higher the temperature of the corresponding temperature range is.
105. And if the first measured temperature belongs to a first abnormal temperature grade, executing a treatment measure for reducing the performance parameter of the processing unit of the equipment located at the first temperature measurement position.
Wherein the performance parameter is a parameter related to power consumption of the device. And the performance parameters of the processing unit include: the dominant frequency or transmit power of the processing unit.
Specifically, if the first measured temperature is within the temperature range corresponding to the first abnormal temperature class in the abnormal temperature classes corresponding to the first temperature measurement position, the first measured temperature belongs to the first abnormal temperature class, and the processing measure corresponding to the first abnormal temperature class and used for reducing the performance parameter of the processing unit of the device at the first temperature measurement position is executed. For example, the main frequency of the processing unit is reduced or the transmission power of the processing unit is reduced.
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 class of the abnormal temperature class corresponding to the modem processor of the mobile phone, the dominant frequency of the modem processor of the mobile phone is reduced according to the processing measure corresponding to the first abnormal temperature class, so as to reduce the power consumption of the modem processor of the mobile phone, and reduce the temperature of the modem processor of the mobile phone.
The embodiment of the invention provides a thermal protection method, which comprises the steps of acquiring each measured temperature of equipment at least one temperature measuring position through a temperature sensor, acquiring preset temperatures at the temperature measuring positions, and comparing each measured temperature with the corresponding preset temperature. If the first measured temperature at the first temperature measuring position exceeds the corresponding preset temperature, determining the abnormal temperature grade of the first measured temperature, and if the first measured temperature is the first abnormal temperature grade, reducing the performance parameters of the processing unit of the equipment at the first temperature measuring position to reduce the power consumption of the equipment, so that the temperature of the equipment is reduced, the phenomenon that the equipment generates overhigh temperature under the condition of continuous use is avoided, and the user experience is improved.
The method, as shown in fig. 2, further includes:
106. and if the first measured temperature belongs to a second abnormal temperature grade, executing a processing measure for feeding back information of overhigh temperature of the processing unit at the first temperature measuring position.
Specifically, if the first measured temperature is within the temperature range corresponding to the second abnormal temperature level in the abnormal temperature levels corresponding to the first temperature measurement position, the first measured temperature belongs to the second abnormal temperature level, and the processing measure corresponding to the second abnormal temperature level is executed, that is, the processing measure corresponding to the second abnormal temperature level is information that the temperature of the processing unit at the first temperature measurement position is too high is fed back, so that a user can know that the temperature of the device is too high through the feedback information, and take a measure for reducing the temperature of the processing unit at the first temperature measurement position, for example, shut down the device or stop running a related application program.
As described in the above example, if the measured temperature at the radio frequency position 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, the processing measure corresponding to the second abnormal temperature level is executed, that is, the information that the temperature at the radio frequency position of the mobile phone is too high is fed back to the mobile phone user, so that the mobile phone user knows that the radio frequency position of the mobile phone is too high, and takes a relevant measure for reducing the temperature at the radio frequency position of the mobile phone, such as a measure for receiving a call.
The method, as shown in fig. 2, further includes:
107. and if the first measured temperature belongs to a third abnormal temperature grade, executing a processing measure for closing all the application programs which are running by the processing unit at the first temperature measuring position.
Specifically, if the first measured temperature is within the temperature range corresponding to the third abnormal temperature level in the abnormal temperature levels corresponding to the first temperature measurement position, and the first measured temperature belongs to the third abnormal temperature level, the processing measure corresponding to the third abnormal temperature level is executed, that is, all the application programs which are running by the processing unit at the first temperature measurement position are closed. For example, the processing unit at the first thermometry location is running the local game and media player, at which time the application associated with the local game and media player is closed.
The method, as shown in fig. 2, further includes:
108. and if the first measured temperature belongs to a fourth abnormal temperature grade, executing a treatment measure for closing the equipment.
Specifically, if the first measured temperature is within the temperature range corresponding to the fourth abnormal temperature level in the abnormal temperature levels corresponding to the first temperature measurement position, the first measured temperature belongs to the fourth abnormal temperature level, and the processing measure corresponding to the fourth abnormal temperature level is executed, that is, the device is turned off.
Through the step 106 and the step 108, different measures for reducing power consumption are taken according to the first measured temperature at the first temperature measuring position of the device, so that the temperature at the first temperature measuring position is reduced, the device is prevented from generating overhigh temperature under the condition of continuous use, and the user experience is improved.
The method, as shown in fig. 3, further includes, after step 105:
109. and acquiring a second measured temperature at the first temperature measuring position through the temperature sensor at the first temperature measuring position.
Specifically, after the performance parameters of the processing unit of the device located at the first temperature measurement position are reduced, 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 master frequency of the modem processor of the mobile phone is reduced, the second measured temperature at the modem processor of the mobile phone is obtained by the temperature sensor at the modem processor of the mobile phone.
110. And if the second measured temperature does not exceed the preset temperature at the first temperature measurement position, restoring the performance parameters of the processing unit of the equipment at the first temperature measurement position to the original values.
Specifically, if the second measured temperature does not exceed the preset temperature at the first temperature measurement position, it indicates that the temperature of the processing unit of the device located at the first temperature measurement position is reduced, and at this time, the performance parameter of the processing unit of the device located at the first 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, determining the abnormal temperature grade of the second measured temperature.
And if the second measured temperature belongs to the first abnormal temperature grade, detecting whether the performance parameter of the processing unit of the equipment located at the first temperature measurement position reaches a minimum value, and if not, further reducing the performance parameter of the processing unit of the equipment located at the first temperature measurement position. If the lowest value is reached, the performance parameters of the processing unit of the equipment located at the first temperature measurement position are not reduced, that is, the performance parameters of the processing unit of the equipment located at the first temperature measurement position are not processed. And if the second measured temperature belongs to a second abnormal temperature grade, feeding back information that the temperature of the processing unit at the first temperature measurement position is too high. And if the second measured temperature belongs to a third abnormal temperature grade, closing all the application programs running by the processing unit at the first temperature measurement position. And if the second measured temperature belongs to a fourth abnormal temperature level, closing the equipment.
It should be noted that the lowest value of the performance parameter of the processing unit of the device located at the thermometric position is preset.
Optionally, as shown in fig. 4, after step 102 and before step 103, the method further includes:
111. and sequencing the measured temperatures at the temperature measuring positions.
As described in the above example, after the measured temperature at the modem processor position of the mobile phone, the measured temperature at the application processor position of the mobile phone, and the measured temperature at the radio frequency position of the mobile phone are obtained, the three measured temperatures are sorted from high to low.
Step 103 of comparing the measured temperature at each of the temperature measurement positions with the corresponding preset temperature includes: and sequentially comparing the measured temperature at each temperature measuring position with the corresponding preset temperature according to the sequence of the measured temperature at each temperature measuring position from high to low.
Specifically, according to the ranking of the measured temperatures at the temperature measurement positions from high to low, the measured temperature at the temperature measurement position with the highest temperature in the ranking is compared with the corresponding preset temperature, and if the measured temperature at the temperature measurement position with the highest temperature in the ranking does not exceed the corresponding preset temperature, the measured temperature at the next temperature measurement position in the ranking is continuously compared with the corresponding preset temperature. And if the measured temperature at the temperature measuring position with the highest temperature in the sequence exceeds the corresponding preset temperature, determining an abnormal temperature grade corresponding to the measured temperature at the temperature measuring position with the highest temperature in the sequence, and performing corresponding measures for reducing the power consumption after determining the abnormal temperature grade corresponding to the measured temperature at the temperature measuring position with the highest temperature in the sequence. And then, continuously comparing the measured temperature at the next temperature measurement position in the sequence with the corresponding preset temperature until the measured temperature at the last temperature measurement position in the sequence is compared with the corresponding preset temperature.
As described in the example above, the measured temperature at the modem processor location of the handset, the measured temperature at the application processor location of the handset, and the measured temperature at the radio frequency location of the handset are ordered from high to low as: a measured temperature at a radio frequency location of the handset, a measured temperature at a modem processor location of the handset, and a measured temperature at an application processor location of the handset.
Firstly, comparing the measured temperature at the radio frequency position of the mobile phone with the highest temperature in the sequence with the corresponding preset temperature, if the measured temperature at the radio frequency position of the mobile phone with the highest temperature exceeds the corresponding preset temperature, determining the abnormal temperature grade of the measured temperature at the radio frequency position of the mobile phone, and if the measured temperature is the second abnormal temperature grade, executing a processing measure corresponding to the second abnormal temperature grade, namely, feeding back information that the temperature at the radio frequency position of the mobile phone is too high. And then, continuously comparing the measured temperature at the position of the modulation and demodulation processor of the mobile phone with the corresponding preset temperature, if the measured temperature at the position of the modulation and demodulation processor of the mobile phone exceeds the corresponding preset temperature, determining the abnormal temperature grade of the measured temperature at the position of the modulation and demodulation processor of the mobile phone, and if the measured temperature is the first abnormal temperature grade, reducing the main frequency of the modulation and demodulation processor of the mobile phone. And continuously comparing the measured temperature at the position of the application processor of the mobile phone with the corresponding preset temperature, and if the measured temperature at the position of the application processor of the mobile phone does not exceed the corresponding preset temperature, comparing the measured temperature at the next temperature measurement position in the sequence with the corresponding preset temperature. Since the measured temperature at the application processor position of the mobile phone is the measured temperature at the last temperature measurement position in the sequence, the process is ended.
The method, as shown in fig. 5, further includes, after step 104:
112. and if the first measured temperatures at the at least two first temperature measuring positions exceed the corresponding preset temperatures, sequencing the abnormal temperature grades 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, the abnormal temperature levels of the at least two first measured temperatures are sorted according to the difference between each first measured temperature and the corresponding preset temperature, and optionally, the abnormal temperature levels of the at least two first measured temperatures are sorted according to the order from high to low of the difference between each first measured temperature and the corresponding preset temperature. And if the abnormal temperature grades of the at least two first measurement temperatures have different abnormal temperature grades, sequencing the abnormal temperature grades of each first temperature measurement temperature according to the abnormal temperature grade of each first temperature measurement temperature.
113. And sequentially executing the processing measures corresponding to the abnormal temperature grades of the processing units at the first temperature measurement positions corresponding to the at least two first measurement temperatures according to the sequence from high to low of the abnormal temperature grades.
Specifically, according to the sorting of the abnormal temperature levels, the processing measure corresponding to the abnormal temperature level of the processing unit at the first temperature measurement position corresponding to the highest abnormal temperature level is executed first. For example, if the highest abnormal temperature level is a third abnormal temperature level, the processing measure corresponding to the third abnormal temperature level of the processing unit at the first temperature measurement position corresponding to the third abnormal temperature level is executed, that is, the processing measure for closing all the application programs running on the processing unit at the first temperature measurement position is executed. Then, the processing measure corresponding to the abnormal temperature grade of the processing unit at the first temperature measurement position corresponding to the next abnormal temperature grade in the sequence is executed until the processing measure corresponding to the abnormal temperature grade of the processing unit at the first temperature measurement position corresponding to the last abnormal temperature grade in the sequence is executed.
As described in the above example, the first measured temperature at the two first temperature measurement positions exceeds the corresponding preset temperature, that is, the measured temperature at the modem processor position of the mobile phone exceeds the preset temperature, and the measured temperature at the radio frequency position of the mobile phone exceeds the preset temperature. And if the abnormal temperature grade of the measured temperature at the position of the modulation and demodulation processor of the mobile phone is determined to be a first abnormal temperature grade, and the abnormal temperature grade of the measured temperature at the position of the radio frequency is determined to be a second abnormal temperature grade, sequencing the two abnormal temperature grades from high to low. According to the sequence of the abnormal temperature grades from high to low, the processing measures corresponding to the second abnormal temperature grade at the radio frequency position of the mobile phone are executed firstly, and the processing measures corresponding to the first abnormal temperature grade at the modulation and demodulation processor of the mobile phone are executed.
It should be noted that, if only the first measured temperature at one first temperature measurement position exceeds the corresponding preset temperature, the corresponding processing measure of the abnormal temperature level of the first measured temperature at the first temperature measurement position is executed.
It should be noted that, the steps 105-108 specifically describe different processing measures corresponding to different abnormal temperature levels.
The embodiment of the invention provides a thermal protection method, which comprises the steps of acquiring each measured temperature of equipment at least one temperature measuring position through a temperature sensor, acquiring preset temperatures at the temperature measuring positions, and comparing each measured temperature with the corresponding preset temperature. If the first measured temperature at the first temperature measuring position exceeds the corresponding preset temperature, determining the abnormal temperature grade of the first measured temperature, and taking different processing measures according to different abnormal temperature grades to reduce the power consumption of the equipment, thereby reducing the temperature of the equipment. Thereby avoiding excessive temperatures of the apparatus under conditions of continued use. After the performance parameters of the processing unit of the equipment at the first temperature measuring position are reduced, a second measured temperature is obtained through the temperature sensor at the first temperature measuring position and is compared with the corresponding preset temperature, and if the second measured temperature does not exceed the corresponding preset temperature, the performance parameters of the processing unit of the equipment at the first temperature measuring position are restored to the original values, so that the equipment is restored to the original efficient state after the temperature is reduced, and the user experience is improved.
