In research and practice process to prior art; the present inventor finds; in the existing scheme one; because the deviation of product power consumption control and heat radiation heat conduction design; battery temperature and PA temperature are in working range; also have surface local position (such as receiver place, architrave place or the hold the place) situation that temperature is high, may have other heat protection point temperature and exceed its allowed band, be damaged.Second existing scheme needs to increase a plurality of temperature sensors, increases cost, increases the power consumption of portable terminal.
Summary of the invention
The embodiment of the invention provides a kind of method and terminal of obtaining terminal temperature.
A kind of method of obtaining terminal temperature comprises:
Detect heat source temperature;
Obtain the surface temperature at corresponding thermo-responsive position according to the surface temperature rise value at described heat source temperature and described a plurality of thermo-responsive positions.
A kind of portable terminal comprises:
Temperature detecting unit is used to detect heat source temperature;
Computing unit is used for obtaining according to described heat source temperature and described surface temperature rise value the surface temperature at corresponding thermo-responsive position.
The embodiment of the invention adopt to detect heat source temperature, obtains the surface temperature at thermo-responsive position according to the surface temperature rise value at heat source temperature and each thermo-responsive position, only needs to detect the surface temperature that heat source temperature can obtain a plurality of thermo-responsive positions; The embodiment of the invention does not increase the surface temperature that temperature sensor can obtain a plurality of thermo-responsive positions, need not increase the power consumption of cost and portable terminal.
Description of drawings
Fig. 1 is the flow chart of an embodiment of a kind of method of obtaining terminal temperature of the present invention;
Fig. 2 is the structure chart of an embodiment of a kind of portable terminal of the present invention.
Embodiment
The embodiment of the invention provides a kind of method of obtaining terminal temperature, and the embodiment of the invention also provides the corresponding mobile terminal.Below be elaborated respectively.
Embodiment one, see also the flow chart of an embodiment of the method that Fig. 1 obtains terminal temperature for the present invention is a kind of.
The a plurality of thermo-responsive position of mobile terminal stores surface temperature rise value; At the research and development test phase, with the temperature difference (being the surface temperature rise value) at heat source temperature (for example PA temperature, battery temperature) and a plurality of thermo-responsive positions (for example receiver, 5 keys, OK key, the battery cover place of holding etc.) of test to deposit portable terminal in than form.
Meanwhile also the tolerance value and the safe temperature value at each thermo-responsive position is stored in the portable terminal.Above-mentioned test phase is mainly by following concrete test case: the test under the limit test under the maximum transmission power, the normal use (10dBm transmitting power), charging measurement etc. detect all temps value.
Step 101, detection heat source temperature;
Portable terminal discharge and recharge or the user when using portable terminal to carry out miscellaneous service, portable terminal utilizes original temperature sensor to detect thermal source, obtains heat source temperature.
Step 102, calculate the surface temperature at each thermo-responsive position;
After detection obtains heat source temperature, calculate the surface temperature at each thermo-responsive position according to surface temperature=heat source temperature-surface temperature rise value.
When the surface temperature at arbitrary thermo-responsive position during, carry out step 104 not in safe range;
Step 103, prompting user or termination thermal source business.
When the surface temperature at arbitrary thermo-responsive position exceeded the hot tolerance value of terminal, the prompting user changed occupation mode;
For example: the surface temperature when arbitrary thermo-responsive position is higher than the hot tolerance value of user, then point out user's " when temperature is higher, please avoid hand-held to use; as far as possible to use earphone or hand-free call, long-time use should as far as possible under the non high temperature environment " contact use when waiting literal or signal language to avoid the user overheated; If the user is professional in charging, then suspend charging.
When the surface temperature at arbitrary thermo-responsive position exceeds the safe temperature value, stop the operation of thermal source business.
For example: when the surface temperature at arbitrary thermo-responsive position surpasses the safe temperature value, and the user then stops the use (such as charging, speech business, data service) of thermal source business after prompting not under holding state; If mobile phone under holding state, then shut down by the prompting back.
The embodiment of the invention only need detect heat source temperature, obtain the surface temperature at thermo-responsive position according to the surface temperature rise value at heat source temperature and each thermo-responsive position, only need to detect the surface temperature that heat source temperature can obtain a plurality of thermo-responsive positions, point out the user when surface temperature at arbitrary thermo-responsive position surpasses safe range or end the thermal source business; The embodiment of the invention does not need to increase the surface temperature that temperature sensor can obtain a plurality of thermo-responsive positions, need not increase the power consumption of cost and portable terminal, can guarantee that each thermo-responsive position of portable terminal is no more than safety value.
