实施例一Embodiment one
本实施例一中，预先通过大量测量，设定第一测量值、第二测量值与校正值的对应关系，供后续方法流程使用，其中第一测量值指示环境温度，第二测量值指示移动终端内部热源温度。In the first embodiment, through a large number of measurements in advance, the corresponding relationship between the first measured value, the second measured value and the correction value is set for use in the subsequent method flow, wherein the first measured value indicates the ambient temperature, and the second measured value indicates the movement Terminal internal heat source temperature.
上述对应关系中的各个第一测量值，是由移动终端处于设定的不同实际环境温度下、并基于设定的不同第二测量值指示的移动终端内部热源温度对环境温度进行测量得出的，该对应关系中的各个校正值，是由对应的第一测量值减去移动终端得出该第一测量值时所处的实际环境温度值得出的。Each of the first measured values in the above corresponding relationship is obtained by measuring the ambient temperature when the mobile terminal is at different set actual ambient temperatures and based on the temperature of the heat source inside the mobile terminal indicated by the different set second measured values. , each correction value in the corresponding relationship is obtained by subtracting the corresponding first measurement value from the actual ambient temperature value where the mobile terminal obtains the first measurement value.
移动终端内部的热源有中央处理器和电源模块等，本实施例一中，在预先设定对应关系时，可以只考虑其中一种主要热源的温度。下面举出一个预先设定对应关系的实例，在该实例中，只考虑移动终端内部一种主要热源的温度，例如中央处理器的温度。The heat sources inside the mobile terminal include a central processing unit and a power module, etc. In the first embodiment, when presetting the corresponding relationship, only the temperature of one of the main heat sources may be considered. An example of a preset corresponding relationship is given below. In this example, only the temperature of one main heat source inside the mobile terminal, such as the temperature of the central processing unit, is considered.
移动终端处于实际环境温度为0度、5度、10度、15度、20度、25度、和30度的环境中，分别基于移动终端内部中央处理器温度为25度、30度、35度、40度、45度、50度、55度、60度、65度、70度、75度、80度和85度的情况，对环境温度进行测量，得到91个第一测量值，然后再将每个第一测量值与得出该第一测量值时所处的实际环境温度值相减，得到对应的校正值。The mobile terminal is in an environment where the actual ambient temperature is 0 degrees, 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, and 30 degrees, based on the temperature of the internal CPU of the mobile terminal being 25 degrees, 30 degrees, and 35 degrees, respectively , 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees and 85 degrees, the ambient temperature is measured to obtain 91 first measured values, and then Each first measurement value is subtracted from the actual ambient temperature value when the first measurement value is obtained to obtain a corresponding correction value.
如下表1给出的校正值，是移动终端处于实际环境温度为25度的环境中，分别基于移动终端中央处理器温度为25度、30度、35度、40度、45度、50度、55度、60度、65度、70度、75度、80度和85度的情况，对环境温度进行测量后得到的。在实际环境温度为其他值的情况下，也可以得到对应的校正值，将所有的校正值汇总，即可得到完整的对应关系，供后续方法流程使用。The correction value given in Table 1 below is that the mobile terminal is in an environment where the actual ambient temperature is 25 degrees, based on the temperature of the central processor of the mobile terminal being 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees and 85 degrees, obtained after measuring the ambient temperature. When the actual ambient temperature is other values, the corresponding correction value can also be obtained, and all the correction values can be summed up to obtain a complete corresponding relationship, which can be used in the subsequent method flow.
表1Table 1
以上实例中给出的实际环境温度和移动终端中央处理器温度仅为一种举例，根据应用的需求，可以设定其他温度值，例如设定移动终端中央处理器温度以1度为间隔，这样在设定对应关系时，将需要测量得到更多的第一测量值。The actual ambient temperature and the temperature of the CPU of the mobile terminal given in the above examples are just examples. Other temperature values can be set according to the requirements of the application. For example, the temperature of the CPU of the mobile terminal is set at intervals of 1 degree, so that When setting the corresponding relationship, it will be necessary to measure and obtain more first measured values.
图1是本发明实施例一中测量环境温度的方法流程图，该流程包括：Fig. 1 is a flow chart of a method for measuring ambient temperature in Embodiment 1 of the present invention, the process comprising:
步骤11：获取当前移动终端对环境温度的第一测量值、及移动终端对内部热源的第二测量值；Step 11: Obtain the first measured value of the current mobile terminal for the ambient temperature and the second measured value of the mobile terminal for the internal heat source;
步骤12：根据预先设定的第一测量值、第二测量值与校正值的对应关系，确定获取的第一测量值及第二测量值对应的校正值；Step 12: According to the preset corresponding relationship between the first measured value, the second measured value and the correction value, determine the correction value corresponding to the obtained first measured value and the second measured value;
步骤13：用获取的第一测量值减去确定出的校正值，得到环境温度测量值。Step 13: Subtracting the determined correction value from the acquired first measurement value to obtain the ambient temperature measurement value.
在上述步骤11中，基于移动终端中感测环境温度的温度传感器可以得到第一测量值，基于移动终端中感测内部热源温度的温度传感器得到第二测量值。In the above step 11, the first measurement value can be obtained based on the temperature sensor in the mobile terminal that senses the ambient temperature, and the second measurement value can be obtained based on the temperature sensor in the mobile terminal that senses the temperature of the internal heat source.
在上述步骤12中，基于预先设定的对应关系，可以确定获取的第一测量值和第二测量值对应的校正值。假设步骤11中获取的第一测量值为28、获取的第二测量值为40，则基于如表1所示的对应关系，可以得到对应的校正值为3。考虑一种特殊的情况，如果表1中没有和步骤11中获取的第一测量值相同的第一测量值，则可以查找与获取的第一测量值相近的第一测量值，如果表1中没有和步骤11中获取的第二测量值相同的第二测量值，则可以查找与获取的第二测量值相近的第二测量值，然后再确定查找出的第一测量值及第二测量值对应的校正值。例如假设步骤11中获取的第一测量值为29、第二测量值为41，则查表时仍然选择第一测量值为28、第二测量值为40所对应的校正值3。应对这种特殊情况的另一种解决方式，是在预先设定对应关系时，将第二测量值的间隔变小，例如变为间隔为1，这样需要测量得到更多的第一测量值，由此可以为步骤12中执行的查找提供更多的参考数据。In the above step 12, based on the preset corresponding relationship, the correction value corresponding to the acquired first measurement value and the second measurement value may be determined. Assuming that the first measured value obtained in step 11 is 28 and the second measured value obtained is 40, based on the corresponding relationship shown in Table 1, the corresponding correction value can be obtained as 3. Consider a special case, if there is no first measured value identical to the first measured value obtained in step 11 in Table 1, you can search for a first measured value close to the first measured value obtained, if in Table 1 If there is no second measured value identical to the second measured value obtained in step 11, a second measured value close to the obtained second measured value can be searched for, and then the first measured value and the second measured value found are determined corresponding correction value. For example, assuming that the first measured value obtained in step 11 is 29 and the second measured value is 41, the correction value 3 corresponding to the first measured value 28 and the second measured value 40 is still selected when looking up the table. Another solution to deal with this special situation is to reduce the interval of the second measurement value when pre-setting the corresponding relationship, for example, the interval is 1, so that more first measurement values need to be measured, This can provide more reference data for the search performed in step 12 .
在上述步骤13中，假设步骤11中获取的第一测量值为28、且步骤12中确定出的校正值为3，则得到校正后的环境温度测量值为25。In the above step 13, assuming that the first measured value obtained in step 11 is 28, and the corrected value determined in step 12 is 3, then the corrected ambient temperature measured value is 25.
作为可选的实施方式，本实施例一中也可以考虑移动终端内部多种热源的温度，例如同时考虑中央处理器温度和电源模块温度，此时在预先设定对应关系的过程中，移动终端测量各个第一测量值时，所基于的不同第二测量值既包括指示中央处理器温度的第二测量值，还包括指示电源模块温度的第二测量值。例如目前表1中所示的第二测量值指示中央处理器温度，在同时考虑中央处理器温度和电源模块温度的情况下，表1中将多出一列指示电源模块温度的第二测量值，基于这样的对应关系，在执行方法流程时，首先获取当前的第一测量值、指示中央处理器温度的第二测量值和指示电源模块温度的第二测量值，然后在预先设定的对应关系中查找获取的第一测量值和第二测量值所对应的校正值，最后用获取的第一测量值减去确定出的校正值，得出环境测量温度。As an optional implementation, in the first embodiment, the temperatures of multiple heat sources inside the mobile terminal can also be considered, for example, the temperature of the central processing unit and the temperature of the power module are considered at the same time. At this time, in the process of presetting the corresponding relationship, the mobile terminal When each first measurement value is measured, different second measurement values based on it include not only the second measurement value indicating the temperature of the CPU, but also the second measurement value indicating the temperature of the power module. For example, the second measurement value shown in Table 1 indicates the temperature of the central processing unit. In the case of considering the temperature of the central processing unit and the temperature of the power supply module at the same time, there will be an additional column in Table 1 indicating the second measurement value of the temperature of the power supply module. Based on such a corresponding relationship, when executing the method flow, first obtain the current first measured value, the second measured value indicating the temperature of the central processing unit, and the second measured value indicating the temperature of the power supply module, and then in the preset corresponding relationship Find the corrected value corresponding to the acquired first measured value and the second measured value, and finally subtract the determined corrected value from the acquired first measured value to obtain the ambient measured temperature.
综上所述，本实施例一中预先通过大量测量，形成第一测量值、第二测量值与校正值的对应关系，在后续的方法流程中，获取当前移动终端对环境温度的第一测量值和移动终端对内部热源温度的第二测量值后，通过查表即可确定对应的校正值，再利用确定出的校正值对获取的第一测量值进行校正，由此可以减小移动终端内部热源的温度对环境温度测量的影响，提高环境温度测量的准确性。To sum up, in the first embodiment, through a large number of measurements in advance, the corresponding relationship between the first measurement value, the second measurement value and the correction value is formed, and in the subsequent method flow, the first measurement of the ambient temperature by the current mobile terminal is obtained. value and the second measurement value of the internal heat source temperature by the mobile terminal, the corresponding correction value can be determined by looking up the table, and then the determined correction value is used to correct the obtained first measurement value, thereby reducing the size of the mobile terminal. The influence of the temperature of the internal heat source on the measurement of the ambient temperature improves the accuracy of the measurement of the ambient temperature.
实施例二Embodiment two
本实施例二中，将实施例一中的对应关系分为更细化的两种对应关系，并基于这两种对应关系提供测量环境温度的方法。In the second embodiment, the corresponding relationship in the first embodiment is divided into two more detailed corresponding relationships, and a method for measuring the ambient temperature is provided based on these two corresponding relationships.
本实施例二中，预先通过大量测量，设定第一测量值、第二测量值与实际环境温度值的第一对应关系，还设定第二测量值、实际环境温度值与校正值的第二对应关系。In the second embodiment, through a large number of measurements in advance, the first corresponding relationship between the first measured value, the second measured value and the actual ambient temperature value is set, and the first corresponding relationship between the second measured value, the actual ambient temperature value and the corrected value is also set. Two correspondences.
下面举出一个预先设定第一对应关系及第二对应关系的实例，在该实例中，只考虑移动终端内部一个主要热源的温度，例如中央处理器的温度。An example of presetting the first corresponding relationship and the second corresponding relationship is given below. In this example, only the temperature of a main heat source inside the mobile terminal, such as the temperature of the central processing unit, is considered.
移动终端处于实际环境温度为0度、5度、10度、15度、20度、25度、和30度的环境中，分别基于移动终端内部中央处理器温度为25度、30度、35度、40度、45度、50度、55度、60度、65度、70度、75度、80度和85度的情况，对环境温度进行测量，得到91个第一测量值，由此可以设定第一测量值、第二测量值和实际环境温度值的第一对应关系，然后再将每个第一测量值与得出该第一测量值时移动终端所处的实际环境温度值相减，得出对应的校正值，由此可以设定第二测量值、实际环境温度值和校正值的第二对应关系。The mobile terminal is in an environment where the actual ambient temperature is 0 degrees, 5 degrees, 10 degrees, 15 degrees, 20 degrees, 25 degrees, and 30 degrees, based on the temperature of the internal CPU of the mobile terminal being 25 degrees, 30 degrees, and 35 degrees, respectively , 40 degrees, 45 degrees, 50 degrees, 55 degrees, 60 degrees, 65 degrees, 70 degrees, 75 degrees, 80 degrees and 85 degrees, the ambient temperature is measured to obtain 91 first measured values, which can Set the first corresponding relationship between the first measured value, the second measured value and the actual ambient temperature value, and then compare each first measured value with the actual ambient temperature value of the mobile terminal when the first measured value is obtained. The corresponding correction value can be obtained by subtracting it, so that the second corresponding relationship between the second measurement value, the actual ambient temperature value and the correction value can be set.

步骤22：根据预先设定的第一测量值、第二测量值与环境实际温度值的第一对应关系，确定获取的第一测量值对应的由第二测量值与环境实际温度值组成的一个以上数组；Step 22: According to the preset first corresponding relationship between the first measured value, the second measured value and the actual temperature value of the environment, determine a corresponding one of the second measured value and the actual temperature value of the environment corresponding to the acquired first measured value the above array;
步骤23：在确定出的所有数组中查找包含获取的第二测量值的数组；Step 23: Find an array containing the acquired second measured value in all determined arrays;
步骤24：根据预先设定的第二测量值、环境实际温度值与校正值的第二对应关系，确定查找出的数组对应的校正值。Step 24: According to the preset second corresponding relationship between the second measurement value, the actual ambient temperature value and the correction value, determine the correction value corresponding to the found array.
步骤25：用获取的第一测量值减去确定出的校正值，得到环境温度测量值。Step 25: Subtracting the determined correction value from the acquired first measurement value to obtain the ambient temperature measurement value.
作为可选的实施方式，在上述步骤22中，可以在第一对应关系中，查找与获取的第一测量值相同或相近的第一测量值，然后确定查找出的第一测量值对应的由第二测量值与实际环境温度值组成的一个以上数组。As an optional implementation, in the above step 22, in the first corresponding relationship, the first measured value that is the same as or similar to the acquired first measured value can be found, and then it is determined that the found first measured value corresponds to More than one array composed of the second measured value and the actual ambient temperature value.
作为可选的实施方式，在上述步骤23中，如果未超找出包含获取的第二测量值的数组，查找包含与获取的第二测量值相近的第二测量值的数组；As an optional implementation, in the above step 23, if an array containing the acquired second measured value is not found, search for an array containing a second measured value that is similar to the acquired second measured value;
假设在上述步骤21中，获取的第一测量值为23度，获取的第二测量值为65度。在上述步骤22中，基于如表2所示的第一对应关系，确定获取的第一测量值23对应的数组为(35,20)、(60,15)和(80,10)。在上述步骤23中，基于如表3所示的第二对应关系，确定第二对应关系中包含与获取的第二测量值65最接近的数组为(65,15)。在上述步骤24中，基于步骤23中确定出的数组(65,15)，确定对应的校正值为9。在上述步骤25中，用获取的第一测量值23减去确定出的校正值9，得出环境温度测量值为14。Assume that in the above step 21, the acquired first measured value is 23 degrees, and the acquired second measured value is 65 degrees.

In the above step 23, based on the second correspondence shown in Table 3, it is determined that the array that is closest to the acquired second measurement value 65 included in the second correspondence is (65, 15). In the above step 24, based on the array (65, 15) determined in step 23, it is determined that the corresponding correction value is 9. In the above step 25 , the determined correction value 9 is subtracted from the acquired first measurement value 23 to obtain the ambient temperature measurement value of 14 .
作为可选的实施方式，本实施例二中也可以考虑移动终端内部多种热源的温度，例如同时考虑中央处理器温度和电源模块温度，此时在预先设定第一对应关系和第二对应关系时，移动终端测量各个第一测量值时，所基于的不同第二测量值既包括指示中央处理器温度的第二测量值，还包括指示电源模块温度的第二测量值。例如目前表2中只列出了中央处理器温度，在同时考虑中央处理器温度和电源模块温度的情况下，表2中还需列出电源模块温度，此时表2中的横轴可以设置为中央处理器温度和电源模块温度的组合，例如横轴的第一格中填写(25,25)，第二格中填写(30,25)等，横轴中可以列出中央处理器温度和电源模块温度的多种组合，此时在设置第一对应关系时，移动终端需基于中央处理器温度和电源模块温度的不同组合对环境温度进行测量，从而得出第一测量值。As an optional implementation, in the second embodiment, the temperatures of multiple heat sources inside the mobile terminal can also be considered, for example, the temperature of the central processing unit and the temperature of the power module are considered at the same time. At this time, the first correspondence and the second correspondence are preset. In this relationship, when the mobile terminal measures each first measurement value, the different second measurement values based on it include not only the second measurement value indicating the temperature of the central processing unit, but also the second measurement value indicating the temperature of the power module. For example, only the temperature of the CPU is listed in Table 2 at present. When the temperature of the CPU and the temperature of the power module are considered at the same time, the temperature of the power module needs to be listed in Table 2. At this time, the horizontal axis in Table 2 can be set It is the combination of CPU temperature and power module temperature. For example, fill in (25,25) in the first column of the horizontal axis, and (30,25) in the second column, etc., and the CPU temperature and Various combinations of power module temperatures, when setting the first corresponding relationship, the mobile terminal needs to measure the ambient temperature based on different combinations of the CPU temperature and the power module temperature, so as to obtain the first measured value.
综上所述，本实施例二中预先通过大量测量，形成第一测量值、第二测量值与实际环境温度值的第一对应关系、及第二测量值、实际环境温度值与校正值的第二对应关系，在后续的方法流程中，获取当前移动终端对环境温度的第一测量值和移动终端对内部热源的第二测量值后，通过查表即可确定对应的校正值，再利用确定出的校正值对获取的第一测量值进行校正，由此可以减小移动终端内部热源的温度对环境温度测量的影响，提高环境温度测量的准确性。To sum up, in the second embodiment, through a large number of measurements in advance, the first corresponding relationship between the first measured value, the second measured value and the actual ambient temperature value, and the relationship between the second measured value, the actual ambient temperature value and the corrected value are formed. The second corresponding relationship, in the subsequent method flow, after obtaining the first measurement value of the current mobile terminal to the ambient temperature and the second measurement value of the mobile terminal to the internal heat source, the corresponding correction value can be determined by looking up the table, and then used The determined correction value corrects the acquired first measurement value, thereby reducing the influence of the temperature of the heat source inside the mobile terminal on the measurement of the ambient temperature and improving the accuracy of the measurement of the ambient temperature.
