Embodiment 1

[0015] Embodiment 1, please refer to figure 1 It is a flowchart of an embodiment of a method for obtaining terminal temperature in the present invention.

[0016] The mobile terminal stores the surface temperature rise of multiple thermally sensitive parts; during the R&D testing stage, the tested heat source temperature (such as PA temperature, battery temperature) is compared with multiple thermally sensitive parts (such as receiver, 5 key, OK key, battery cover handle) The temperature difference (that is, the surface temperature rise) is stored in the mobile terminal in the form of a ratio table.

[0017] At the same time, the tolerance value and safe temperature value of each heat-sensitive part are also stored in the mobile terminal. The above-mentioned test phase mainly passes through the following specific test cases: limit test under the maximum transmission power, test under normal use (10dBm transmission power), charging test, etc. to detect various temperature valu...

Abstract

The invention discloses a method for obtaining terminal temperature, the embodiment of the invention also provides a corresponding movable terminal, comprising the following steps of: storing surface temperature rise values of a plurality of heat-sensitive parts; detecting heat source temperature; obtaining the surface temperature of the corresponding heat-sensitive parts according to heat source temperature and the surface temperature rise values of a plurality of heat-sensitive parts. As the proposal of the invention adopts the steps of detecting the heat source temperature and obtaining the surface temperature of the heat-sensitive parts according to heat source temperature and the surface temperature rise values of all the heat-sensitive parts, the surface temperature of a plurality of heat-sensitive parts can be obtained only when detecting the heat source temperature, thus controlling the temperature of any heat-sensitive part to be below safe temperature.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for acquiring terminal temperature and a terminal. Background technique [0002] Existing mobile terminals will generate a certain amount of heat during use, and the generated heat will cause the temperature of the mobile terminal to rise. When the temperature rises to a certain range, it will affect the performance of the mobile terminal and even cause danger. There are two solutions to this problem. One is to use a temperature sensor to detect the temperature of the heat source (such as the temperature of the battery, the temperature of the power amplifier (PA, Power amplifier)) when the user is charging and discharging. If the temperature of the heat source exceeds the operating temperature range of the device, then Prompt the user or suspend the operation of the device to avoid accidents; the second is to add a temperature sensor to detect the surface ...
