Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

The terms "first", "second", etc. in the present invention are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "include" and "have", as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but optionally also includes unlisted steps or units, or optionally further includes For other steps or units inherent in these processes, methods, products or apparatuses.

Reference herein to an "embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the present invention. The occurrences of this phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is understood explicitly and implicitly by those skilled in the art that the embodiments described herein can be combined with other embodiments.

The communication device provided by the embodiment of the present invention may be a mobile phone, a tablet computer, a smart wearable device, and the like.

Please refer to FIG. 1. FIG. 1 is a schematic flowchart of an embodiment of a method for suppressing temperature rise of communication equipment provided by the present invention. The method includes:

Step 11: When receiving an incoming call, detect whether the communication device is in a charging state.

Wherein, incoming calls include voice calls and video calls. In addition, in other embodiments, calls in application software may also be included, for example, voice calls and video calls in QQ or WeChat.

Wherein, the communication device can be charged by connecting to an external power source through a charging interface, for example, it can be plugged into an external power socket through a power plug, and can also be connected to a mobile power source through a USB cable. In addition, wireless charging is also possible. Therefore, when detecting whether the communication device is in the charging state, the voltage of the external charging interface (USB interface) of the communication device can be detected, and the change of the electric quantity of the battery can also be detected.

Step 12: If yes, obtain the current power level of the communication device as the first power level.

Wherein, the current electric quantity can be acquired in various ways.

The voltage test method is obtained by monitoring the battery and based on the relationship between voltage and power. Nowadays, the batteries of communication equipment are generally lithium batteries. The discharge curve of lithium batteries is not a straight line, that is, the relationship between power and voltage is not linear, so the test method is not accurate, and the power measurement accuracy is only more than 20%. Especially when the battery power is lower than 50%, the power calculation of the mobile phone will become very inaccurate.

Battery modeling method, this method is to build a data table according to the discharge curve of the battery, and the power value under different voltages will be marked in the data table, this method can effectively improve the measurement accuracy. But it is not easy to obtain an accurate data sheet, because the relationship between voltage and power also involves factors such as battery temperature, self-discharge, and aging. Only by combining many factors for correction can a satisfactory power measurement be obtained.

Coulomb meter measurement method, the coulomb meter is a current detection resistor connected in series with the positive and negative electrodes of the battery. When a current flows through the resistor, Vsense (induced voltage) will be generated. By detecting Vsense, the current flowing through the battery can be calculated. Therefore, it can accurately track the change of battery power, and the accuracy can reach 1%. In addition, by cooperating with the battery voltage and temperature, it can greatly reduce the influence of factors such as battery aging on the measurement results.

Step 13: When the duration of the call is greater than the set time threshold, acquire the current power level of the communication device as the second power level.

Wherein, the set time threshold may be 5 minutes. At that time, the time threshold could be set arbitrarily, and users could set it according to their own calling habits. In addition, the system can also obtain the user's calling habits through big data, and set them according to the user's habits. For example, the call time of user A is generally divided into two situations, one is short, less than 1 minute, such calls are generally sales promotion and fraud; the other is longer, generally greater than 10 minutes, therefore, This time threshold can be set relatively small, such as 2 minutes. As long as the time is greater than 2 minutes, it can be indicated that the user will talk for a long time, and step 14 can be performed to adjust the charging strategy.

Wherein, when the call starts, the timer of the communication device starts timing, and when the time is greater than the set time threshold, the current power is acquired again.

It is understandable that it is very dangerous to charge a communication device during a call. On the one hand, the voltage of a communication device during charging is higher than when it is in standby mode. Usually many times, it is easy to damage the sensitive and complicated parts inside the communication equipment, which leads to frequent maintenance of communication equipment; on the other hand, the radiation during charging is also dozens of times higher than usual, which will cause damage to the human body.

When the communication device is charging and talking, it is equivalent to charging and discharging the battery at the same time. If the charge is greater than discharge during this period, the power of the battery will increase. If the charge is less than discharge during this period, the power of the battery will decrease.

In addition, during the process of charging and talking simultaneously, the communication device may also run other applications, and other applications may still be uploading or downloading data.

Step 14: If the second electric quantity is greater than the first electric quantity, adjust the charging strategy of the communication device.

In this implementation, when the second electric quantity is greater than the second electric quantity, it indicates that the charging capacity of the communication device is greater than the discharging capacity. The charging strategy of communication equipment to reduce the temperature rise caused by charging.

Optionally, the current charging strategy of the communication device may be obtained first, and the current charging strategy may be adjusted. Specifically, in one embodiment, if the current charging strategy is constant voltage charging, adjust to constant current charging; in another embodiment, if the current charging strategy is constant current charging, then reduce the charging current.

Among them, during constant voltage charging, the voltage of the charging power source maintains a constant value throughout the charging time, and the current gradually decreases as the battery terminal voltage gradually increases. If the constant voltage charging is performed when the battery power is low, the charging current at this time is relatively large. Therefore, the constant voltage charging can be adjusted to constant current charging, and the current of the constant current charging is relatively small. For example, it can be 350mA.

Among them, during constant current charging, regardless of the amount of battery power, the current is maintained at a constant value for charging. Generally, the current of constant current charging is relatively large, reaching 700mA-1000mA, and the current of constant current charging in the existing fast charging strategy even reaches 2000mA. Therefore, the constant current charging current can be reduced, for example, it can be 350mA.

In addition, the battery charging of communication equipment also uses a combination of constant current and constant voltage charging. As shown in Figure 2, in the constant current charging stage, the charging current is I1. If a call is in progress at this time, the charging current can be adjusted. I2; in the constant voltage charging stage, the current decreases continuously. If you are talking at this time, because the current is small at this time, you can not adjust the current, or you can reduce the current, and use the current I3 for constant current charging. In addition , It can also be adjusted to trickle charging, which uses pulse current to implement intermittent charging.

In addition, in an embodiment, no matter what the current charging strategy is, when charging and talking are performed at the same time, the current charging strategy can be adjusted to trickle charging. Wherein, the current value during trickle charging is also relatively small, for example, it may be 350mA.

In this embodiment, when an incoming call is received, it is detected whether the communication device is in a charging state; if so, the current power level of the communication device is acquired as the first power level; when the call duration is greater than the set time threshold, the current power level of the communication device is acquired is the second electric quantity; if the second electric quantity is greater than the first electric quantity, adjust the charging strategy of the communication device. Through the above method, the charging strategy of the communication device can be adjusted to prevent the subsequent temperature rise of the communication device when the communication device is charging and talking at the same time, which plays a preventive role in advance. On the one hand, it can prevent damage to the communication device and prolong its service life. On the other hand, the security performance of the communication equipment is improved.

Referring to Fig. 3, Fig. 3 is a schematic flowchart of another embodiment of the method for suppressing the temperature rise of communication equipment provided by the present invention, the method includes:

Step 31: When receiving an incoming call, detect whether the communication device is in a charging state.

Step 32: If yes, obtain the current power level of the communication device as the first power level.

Step 33: When the call duration is greater than the set time threshold, acquire the current power level of the communication device as the second power level.

Step 34: If the second electric quantity is greater than the first electric quantity, and the second electric quantity is greater than the set electric quantity threshold, reduce the charging current.

It can be understood that, in this embodiment, if the second electric quantity is small, it means that the battery still needs to be charged a large amount. In order to ensure the normal operation of the communication device, the current charging strategy is not adjusted; if the second electric quantity is large, It shows that the power of the battery can maintain the normal operation of the communication device for a period of time, then the charging strategy can be adjusted to reduce the charging current.

Wherein, the set power threshold may be 20%.

Referring to Fig. 4, Fig. 4 is a schematic flowchart of another embodiment of the method for suppressing the temperature rise of communication equipment provided by the present invention, the method includes:

Step 41: When receiving an incoming call, detect whether the communication device is in a charging state;

Step 42: If yes, obtain the current power level of the communication device as the first power level;

Step 43: When the call duration is greater than the set time threshold, acquire the current power level of the communication device as the second power level, and acquire the temperature of the communication device;

Step 44: If the second electric quantity is greater than the first electric quantity, and the temperature is greater than the set temperature threshold, reduce the charging current.

Wherein, the temperature of the communication device can be obtained by a temperature sensor, for example, it can be measured by a thermistor. Specifically, the temperature at any other location of the battery, CPU, display screen or communication device may be collected.

In this embodiment, the temperature of the communication device is also detected. If the temperature is low, it means that the current device has fewer applications or the ambient temperature is low. Even if charging and talking are carried out at the same time, it will not cause a high temperature rise of the communication device. , so it is not necessary to adjust the charging strategy of the device; if the temperature is high, it means that the temperature of the device will continue to rise after charging and calling at the same time for a period of time. In order to prevent further temperature rise, the charging strategy needs to be adjusted .

Referring to FIG. 5, FIG. 5 is a schematic flowchart of another embodiment of the method for suppressing the temperature rise of communication equipment provided by the present invention, the method includes:

Step 51: When receiving an incoming call, detect whether the communication device is in a charging state.

Step 52: If yes, obtain the current power level of the communication device as the first power level.

Step 53: Detect that the call duration is greater than the set time threshold.

Step 54: If yes, obtain the current power level of the communication device as the second power level.

Step 55: Determine whether the second electric quantity is greater than the first electric quantity.

Step 56: If yes, determine whether the current power is greater than the set power threshold.

Step 57: If yes, check whether the current temperature is greater than the set temperature threshold.

Step 58: If yes, adjust the charging policy of the communication device.

Step 59: After the call ends, adjust the charging policy of the communication device according to the current battery capacity of the communication device.

Wherein, in step 59, the charging strategy may be adjusted to the previous charging strategy after the call ends, that is, the charging voltage and the charging current are adjusted according to the current charging power.

It can be understood that, in this embodiment, the charging strategy of the communication device is adjusted only when multiple conditions such as the duration of the call, the size of the second battery, and the current temperature are satisfied at the same time.
