Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
It should be noted that, based on the measurement of the ambient temperature implemented by the mobile phone, if a new temperature sensor is added to the outer surface of the mobile phone, the hardware cost is increased, and the obtained ambient temperature value is also inaccurate.
An embodiment of the present disclosure provides a temperature measurement method, and fig. 1 is a flowchart illustrating a temperature measurement method according to an exemplary embodiment, and as shown in fig. 1, the temperature measurement method includes the following steps:
and 103, determining the environment temperature of the space where the mobile terminal is located based on the temperature value and the influence value.
It should be noted that the temperature measurement method may be applied to any mobile terminal, and the mobile terminal may be: a smart phone, a tablet computer, or a wearable electronic device, etc.
The mobile terminal contains a plurality of temperature sensors distributed around each heating component in advance for detecting the temperature of the heating component. The heat generating component includes a device that emits heat during operation, such as a System On Chip (SOC), various functional chips (e.g., a processing Chip of a power supply or a processor CPU), or a sensor with high power consumption. A temperature sensor is arranged beside the SOC and used for detecting the temperature of the CPU; and a temperature sensor is arranged beside the battery and used for detecting the temperature of the battery.
According to the temperature measurement method disclosed by the embodiment of the disclosure, the environment temperature of the environment where the mobile terminal is located is detected based on the original temperature sensor in the mobile terminal without additionally adding a temperature sensor.
Here, a temperature sensor may be placed beside each heat generating component to detect the temperature of the heat generating component. The heat generating components may be divided into a plurality of regions according to the layout of the positions, and the temperature sensor may be disposed in each region near the center. The present disclosure does not limit the placement position of the temperature sensor within the mobile terminal.
Fig. 2 is a schematic diagram of a smart phone with a plurality of temperature sensors inside, according to an exemplary embodiment, and as shown in fig. 2, the smart phone includes 5 temperature sensors 200 distributed at different positions.
The temperature sensor 200 includes: a thermistor or thermocouple; such as a thermistor having a Negative Temperature Coefficient (NTC). The temperature sensor 200 is used to detect the temperature of each heat generating component, and the detected temperature can be used for various subsequent operations. For example, the detected temperature can be used to determine whether various heat generating components in the mobile terminal are too hot, and then send out a high temperature warning. As another example, the detected temperature may also be used to determine an ambient temperature of the environment in which the mobile terminal is located.
The following describes an application of "the detected temperature is used to determine the ambient temperature of the environment in which the mobile terminal is located".
In the embodiment of the present disclosure, the temperature value collected by each temperature sensor located inside the mobile terminal is affected by at least two factors: ambient temperature factors and heat generation factors of heat generating components within the mobile terminal.
Since the environment in which the mobile terminal is located has a certain amount of heat, the heat is transferred to a temperature sensor located in the mobile terminal. In addition, when the mobile terminal is operated, heat generated by a heat generating component located in the mobile terminal is also transferred to the temperature sensor. The temperature value collected by the temperature sensor in the mobile terminal is then substantially composed of the two portions of heat. Thus, for each temperature sensor, the temperature value collected is a combination of the ambient heat transferred and the heat generated by the various heat generating components transferred.
Then, when the ambient temperature is detected based on the temperature sensor, the sum of the temperature change values caused by the heat generated by each heat generating component transferred to the temperature sensor may be removed from the temperature values collected by the temperature sensor, so as to obtain the ambient temperature of the space where the mobile terminal is located.
Here, the influence value of the heat generation of the heat generating component on the temperature acquisition of the temperature sensor includes: the heat generated by each heat generating component located in the mobile terminal is transferred to the temperature sensor, resulting in the sum of the temperature change values of the temperature sensor. For example, assume that there are only 2 heat generating components inside the mobile terminal: SOC and battery; wherein the heat generation of the SOC is E1, and the heat generation E1 is transmitted to the temperature sensor P1 to enable the measured value of the temperature sensor P1 to be increased by X ℃, namely the temperature change value on the temperature sensor P1 is X ℃. And the heat generation of the battery is E2, and the measured value of the temperature sensor P1 is increased by Y ℃ after the heat generation E2 is transmitted to the temperature sensor P1, that is, the temperature change value on the temperature sensor P1 is Y ℃, so that the influence value of the heat generation of the heat generating component inside the mobile terminal on the temperature acquisition of the temperature sensor P1 is X + Y ℃.
Here, the X and Y may be determined by experimental values, that is, when the mobile terminal is used in an environment of 0 ℃, the collected value of the temperature sensor beside the heat generating component is the amount of heat generated by the heat generating component (i.e., the X or Y). Or the mobile terminal is used in a constant temperature environment, X or Y may be determined based on a collected value of a temperature sensor beside the heat generating component and a temperature value of the constant temperature environment.
As a specific example, assume that the mobile terminal contains 3 heat generating components inside: SOC, battery and sensor; a temperature sensor P1 is provided near the SOC. Then, in the application of detecting the ambient temperature based on the temperature sensor P1, the temperature value W detected at P1 is: a first temperature change value W1 caused by the transfer of ambient heat to P1 and a second temperature change value W2 caused by the transfer of heat generated by the internal SOC, battery and sensor of the mobile terminal to P1. The second temperature change value W2 is specifically the sum of temperature change values caused by the heat generation of the SOC, the battery, and the sensor being transmitted to the P1, respectively. Assuming that the temperature value W collected by P1 is 50 ℃, it is determined that W2 is 30 ℃, and W1 is 20 ℃. Here, the first temperature change value W1 caused by the transfer of the ambient heat to P1 is the ambient temperature value.
Therefore, in the temperature measurement method in the embodiment of the disclosure, because other temperature sensors are not newly introduced, the detection of the external temperature is realized only based on the original temperature sensor in the mobile terminal, and the hardware cost is not increased. In addition, the original temperature sensor in the mobile terminal is positioned in the mobile terminal, and the acquired temperature value not only reflects the external ambient temperature, but also reflects the heat production condition of a heating component in the mobile terminal, so that the accurate ambient temperature can be acquired based on the temperature value and the influence value acquired by the temperature sensor.
It should be noted that, in some embodiments, when the mobile terminal includes a plurality of heat generating components inside and includes a plurality of temperature sensors, the ambient temperature measured in the temperature measurement method may be: the ambient temperatures measured by the plurality of temperature sensors are averaged. In other embodiments, when the mobile terminal includes a plurality of heat generating components and a plurality of temperature sensors, the ambient temperature measured in the temperature measuring method may be: the ambient temperature measured by the temperature sensor closest to the position of the mobile terminal housing. Here, the temperature sensor located closer to the housing is more advantageous in detecting the ambient temperature because it is located closer to the external environment.
That is, in order to detect the temperature more accurately, in some embodiments, a temperature sensor located closer to the housing in the mobile terminal may be selected to determine the ambient temperature. Here, the temperature sensor closer to the housing is located closer to the external environment, and in the collected temperature value, the heat of the environment where the mobile terminal is located is transferred to a large extent, while the influence value of the heat generation of the heat generating component inside the mobile terminal on the temperature collection of the temperature sensor is smaller, which is more favorable for detecting the ambient temperature.
It should be noted that, when the mobile terminal is in different operating states, the operating states of the heat generating components may be different, and the heat may be generated differently. Then, in some implementations, the influence value of the heat generation of the heat generating component in the mobile terminal on the temperature acquisition of the temperature sensor can be determined according to the operating state of the heat generating component.
The operating conditions of the heat generating component may include: the SOC/CPU is in a high operation state, the memory is in a read-write state, the screen is in a bright screen state and/or the battery is in a use state. Then, after the temperature value acquired by the temperature sensor in the mobile terminal is acquired, it is further determined that the influence value of heat generation on the temperature acquisition of the temperature sensor when the heating component is in the corresponding running state is determined, and the environmental temperature of the space where the heating component is located is determined by combining the temperature value and the influence value. The specific mode of determination is explained below.
Fig. 3 is a schematic diagram illustrating an exemplary embodiment of determining an ambient temperature of a heat generating component of a mobile terminal in different operating states, and as shown in fig. 3, the ambient temperature of a space in which the heat generating component is located may be determined according to information such as a CPU frequency, a memory state, a screen state, and a battery state, and a temperature value collected by a temperature sensor.
Here, the CPU frequency is used to represent whether the CPU is in a high operation state.
The memory state includes: the memory is in a read-write state.
The screen states include: and (5) a bright screen state.
The battery state includes: the use state.
Taking the battery state as an example, when the battery of the mobile terminal is in a use state, the operation state of the battery is a high-load operation, and the heat generation of the battery is higher compared with a low-load operation, so that the influence value of the heat generation of the battery on the temperature acquisition of the temperature sensor is higher in the case.
The determination of the ambient temperature of the space where the mobile terminal is located may be performed according to a preset processing cycle, that is, the determination of the ambient temperature of the space where the mobile terminal is located may be performed once at intervals of the preset processing cycle. Thus, the environment temperature can be grasped, and the processing power consumption of the system is not increased too much.
The determination of the environmental temperature of the space where the mobile terminal is located may also be performed after receiving the environmental temperature acquisition instruction. Therefore, the acquisition based on actual needs meets the needs of users better, and unnecessary processing cost can be reduced.
In some embodiments, fig. 4 is a flow chart illustrating another thermometry method according to an exemplary embodiment, as shown in fig. 4, the thermometry method further comprising:
and 104, sending a temperature adjusting instruction to temperature adjusting equipment in the space where the mobile terminal is located according to the environment temperature.
Here, the temperature adjusting apparatus includes: a first temperature regulating device for cooling and/or a second temperature regulating device for heating. The first temperature adjustment device includes: fans, air coolers or refrigeration air conditioners; the second temperature adjustment device includes: a fan heater or a heating air conditioner.
The temperature adjustment instructions include: a first temperature adjustment command for cooling and/or a second temperature adjustment command for heating.
The mobile terminal can bring a plurality of excellent linkage functions after detecting the ambient temperature of the external environment based on the original temperature sensor in the mobile terminal. For example, when it is detected that the temperature of a room where the mobile terminal is located is high, a first temperature adjustment instruction may be issued to start a fan or turn on an air conditioner. For example, when the temperature of the room where the mobile terminal is located is detected to be low, a second temperature adjustment instruction may be issued to turn on the warm air.
Therefore, the corresponding control instruction can be sent out directly based on the obtained ambient temperature, more linkage functions are realized, and the use scene of the mobile terminal is enriched.
In some embodiments, the instruction to display the temperature may also be issued directly to a display of the mobile device.
After the ambient temperature of the space where the mobile terminal is located is detected, the value of the ambient temperature is directly sent to the display to be displayed, so that the user can master the ambient temperature of the space where the mobile terminal is located, and the daily life of the user is facilitated.
In some embodiments, the determining the influence value of heat generation of a heat generating component in the mobile terminal on the temperature acquisition of the temperature sensor comprises:
determining the influence weight of at least one heating component on the temperature acquisition of the temperature sensor according to the running state of the at least one heating component in the mobile terminal;
determining an impact value of heat production by the at least one heat-generating component on the temperature acquisition of the temperature sensor based on the impact weight.
Here, the operation state of the heat generating component may include: the SOC/CPU is in a high operation state, the memory is in a read-write state, the screen is in a bright screen state and/or the battery is in a use state.
When the mobile terminal is in different working states, the operating states of the heat generating components are different. For example, when the mobile terminal is in a charged state, the operating state of the battery is a high load operation, and the SOC and sensors are low loads. For another example, when the mobile terminal is in a high operation state, the operation state of the SOC is a high load operation, but the battery and the sensor are low loads.
Furthermore, the heat generating components generate different amounts of heat in different operating states. For example, when the SOC is operating at high load, heat generation may be greater than when operating at low load. While the heat generation is different, the weight of the influence on the temperature acquisition of the temperature sensor is also different. In other words, the heat generating components generate heat under different operating conditions, and influence weights of the heat generating components on temperature acquisition of the temperature sensor are different.
For example, assuming that the heat generation when the SOC is in the high operation state is 80 cards, the measured value of the temperature sensor P1 is increased by 8 ℃ after the heat generation is transmitted to the temperature sensor P1. And the heat generation at the SOC in the low load operation state is 30 calories, which is transferred to the temperature sensor P1 to raise the measurement value of the temperature sensor P1 by 3 ℃. While 8 c has a greater weight on temperature sensor temperature acquisition than 3 c.
Then, after determining the influence weight of each heat-generating component on the temperature acquisition of the temperature sensor, the influence value of the heat generation of each heat-generating component on the temperature acquisition of the temperature sensor can be determined directly based on the influence weight.
Here, the determination of the influence weight may be based on an empirical value in historical use, that is, in historical use, the influence weight is determined based on a relationship between temperature values collected by the respective temperature sensors in the respective operating states.
In other embodiments, the determination of the influence weight may also be calculated and determined based on layout information and heat generation capability of various components inside the mobile terminal. The present disclosure is not so limited.
In the embodiment of the present disclosure, determining an influence value of heat generation of each of the heat generating components on temperature acquisition of the temperature sensor based on the influence weight includes: and determining an influence value on the temperature acquisition of the temperature sensor based on the influence weight and the temperature value corresponding to the heat production of the heat-generating component.
The temperature value corresponding to the heat generation of the heat generating component represents the temperature value of the heat generating component itself, that is, the temperature value formed by the heat generated during the heat generation.
Determining an influence value for temperature acquisition of a temperature sensor based on the influence weight and a temperature value corresponding to heat production of a heat-generating component, comprising: the sum of the products of the influence weight of each heating component and the temperature value corresponding to the heat generation of the heating component is determined as the influence value on the temperature acquisition of the temperature sensor.
For example, assuming that the heat generation when the SOC is in the high operation state has an influence weight on the temperature acquisition by the temperature sensor of 0.7, while at this time, the influence weight on the temperature acquisition by the heat generation by the battery is 0.2, and the influence weight on the temperature acquisition by the heat generation by other heat generating components is 0.1; the temperature value corresponding to heat generation of the SOC is 50 ℃, the temperature value corresponding to heat generation of the battery is 20 ℃, the temperature value corresponding to heat generation of other heat generating components is 10 ℃, and the influence value is 50 × 0.7+20 × 0.2+10 × 0.1 — 40.
Here, the influence weight and thus the influence value are determined by the operating state of the heat generating component, and the determined influence value is more accurate due to the combination of the operating state of the heat generating component.
In some embodiments, the determining the weight of the influence of the heat generating component on the temperature acquisition of the temperature sensor according to the operating state of at least one heat generating component in the mobile terminal includes:
acquiring an initial value of the influence weight corresponding to the heating component; wherein the initial value is determined according to the heat generating capacity of the corresponding heat generating component and/or the distance between the heat generating component and the temperature sensor;
and determining the influence weight according to the running state of at least one heating component in the mobile terminal and the initial value.
Here, the initial value of the influence weight corresponding to the heat-generating component is determined based on the heat-generating capacity of the corresponding heat-generating component and/or the distance from the temperature sensor.
In some embodiments, the initial value of the weight may be a corresponding weight value for the heat-generating component when operating at full load. It may also be a corresponding weight value when the heat generating component operates at a certain load rate. The certain load rate includes: the load factor at which the heat generating components are most often placed. For example, the SOC is most often at 40% load condition.
Regarding the determination of the initial values of the impact weights: since the heat transferred to the temperature sensor is affected by the heat generating capacity of the internal heat generating component and/or by the distance between the heat generating component and the temperature sensor, no matter what operating state the mobile terminal is in. In this way, an initial value of the influence weight may be determined for each heat-generating component based on the heat-generating capacity of the heat-generating component and/or the distance from the temperature sensor.
No matter what kind of operating condition the mobile terminal is in, the SOC is in the state of generating heat, and only in different operating conditions, the heat generation is different. Moreover, regardless of the operating state of the mobile terminal, the heat generating capacity of the SOC is greater than that of other components. In other words, no matter what operating state the mobile terminal is in, the SOC will affect the collection of the temperature sensor. Then, the initial values of the influence weights of the other heat generating components may be set with the initial value of the influence weight of the SOC as a reference.
Here, determining the influence weight according to the operating state of at least one heat generating component in the mobile terminal and the initial value includes: determining an operation coefficient according to the operation state of the heating component; determining the impact weight based on a product of the operating coefficient and the initial value.
The operation coefficient may be determined according to the operation state of the heat generating component. And the operating state of the heat generating component determines the current load factor of the heat generating component. For example, taking the value corresponding to the heat generating component at the full load operation as an initial value, when the SOC is in the highest-level high operation state, the SOC may be considered as the full load operation, and the operation coefficient corresponding to the full load operation may be considered as 1, that is, the initial value is not converted.
As a specific example, assuming that the initial value of the influence weight corresponding to the SOC is 0.7, and assuming that the SOC is in a high operation state at this time, it is considered as full load operation, and the operation coefficient corresponding to the full load operation is 1, the influence weight is determined by combining the operation state of the heat generating component and the initial value, that is: 1 × 0.7 ═ 0.7.
In some embodiments, the initial value is inversely related to a distance between the corresponding heat generating component and the temperature sensor; and/or; is positively correlated with the heat generating capacity of the corresponding heat generating component.
Here, the farther the distance between the heat-generating component and the temperature sensor is, the less heat is transferred from the heat-generating component to the temperature sensor. The greater the heat generating capacity of the heat generating component, the greater the amount of heat generated by the heat generating component is transferred to the temperature sensor.
In the embodiment of the present disclosure, the initial value of the influence weight corresponding to the heat generating component may be determined based on the correlation.
Specifically, the manner of determining the initial value may be:
in some embodiments, the obtaining an initial value of the impact weight for the heat-generating component includes:
and inputting the temperature value acquired by the temperature sensor of the at least one heating part in the corresponding running state into a preset target neural network model to obtain an initial value of the influence weight corresponding to the heating part.
In embodiments of the present disclosure, the target neural network model may be determined based on a distance between the heat-generating component and the temperature sensor, and/or a heat-generating capacity of the heat-generating component.
The target neural network model is obtained by training a preset neural network model, and the preset neural network model may include: a long-short term memory model, or a back propagation neural network model.
The inputting a preset target neural network model to the at least one heating component in a corresponding operating state based on the temperature value acquired by the temperature sensor to obtain an initial value of the influence weight corresponding to the heating component includes:
inputting the temperature value acquired by the temperature sensor, the distance between the heating component and the temperature sensor, the running coefficient corresponding to the running state and the corresponding heat productivity during full-load running into a preset target neural network model to obtain the initial value of the influence weight corresponding to the heating component.
In some embodiments, a plurality of temperature sensors are contained within the mobile terminal; wherein the plurality of temperature sensors includes:
a first temperature sensor having a first distance from a housing of the mobile terminal, and,
a second temperature sensor having a second distance from a housing of the mobile terminal, wherein the second distance is greater than the first distance;
the determining the environmental temperature of the space where the mobile terminal is located based on the temperature value and the influence value includes:
and determining the ambient temperature of the space where the mobile terminal is located based on the temperature value acquired by the second temperature sensor and the influence value of the heat generation of the heat generating component in the mobile terminal on the temperature acquisition of the second temperature sensor.
Here, the second temperature sensor is closer to the housing of the mobile terminal than the first temperature sensor. The temperature sensor closer to the housing is closer to the external environment, so that the ambient temperature is more occupied in the temperature value collected by the second temperature sensor, the influence value of heat generation of the heat generating component on the temperature collection of the second temperature sensor is smaller, and compared with the temperature sensor located more inside the mobile terminal, the ambient temperature is determined more accurately by the second temperature sensor due to relatively less interference in the determination of the ambient temperature.
Thus, in the embodiment of the present disclosure, when the mobile terminal includes a plurality of temperature sensors inside, the temperature sensor relatively closest to the mobile terminal housing may also be directly selected to determine the ambient temperature. Therefore, on one hand, the accuracy of environment temperature detection can be improved; on the other hand, the temperature values collected by all the temperature sensors in the mobile terminal do not need to be processed (in the averaging mode), and the ambient temperature can be determined only based on the temperature sensor closest to the shell of the mobile terminal, so that the calculation amount is reduced, the calculation process is simplified, and the determination of the ambient temperature is facilitated.
In some embodiments, the heat generating component comprises at least one of:
a system-on-chip SOC;
a processor CPU;
a memory;
a screen;
a battery.
Here, the heat generating component includes: devices that dissipate heat during operation.
The heat generating component further includes: system On Chip (SOC), other various functional chips (e.g., processing Chip for power supply), or sensors with high power consumption. Under different operating conditions, the heat generating components generate different amounts of heat.
The temperature measuring method provided by the embodiment of the disclosure determines the environmental temperature of the space based on the influence value of the temperature value acquired by the temperature sensor in the mobile terminal and the heat generated by the heating component in the mobile terminal on the temperature acquisition of the temperature sensor in the mobile terminal. Because other temperature sensors are not newly introduced, the detection of the external temperature is realized only based on the original temperature sensors in the mobile terminal, and the hardware cost is not increased. In addition, the original temperature sensor in the mobile terminal is positioned in the mobile terminal, and the acquired temperature value not only reflects the external ambient temperature, but also reflects the heat production condition of a heating component in the mobile terminal, so that more accurate ambient temperature can be acquired based on the temperature value and the influence value acquired by the temperature sensor.
