Technical Field

The invention relates to the technical field of terminal equipment, in particular to a shutdown early warning method, a shutdown early warning device, a shutdown early warning medium and shutdown early warning equipment.

Background

With the rapid development of the electronic industry and communication technology, smart home devices such as mobile phones, smart speakers, smart bracelets and the like are increasing, and people's lives become more and more intelligent. Due to the portability of the mobile phone and the capability of downloading application software with various functions from an application store, the mobile phone has become an essential necessity in daily life.

The battery power of the mobile phone is often insufficient because the mobile phone is frequently used, and when the battery power is reduced, the system is suddenly shut down because the power is cut off. The main reasons for the power cut are: when the handset is low on battery or the ambient temperature, "polarization loss" and the lithium ion battery-related "impedance" become very high, the same power/surge fluctuations caused by the handset performing different procedures and functions will result in larger voltage fluctuations, and when the voltage fluctuations reach or fall below a low voltage threshold (threshold), the battery low voltage protection mechanism will be activated to shut off the power supply. Therefore, the use experience of the user is seriously influenced by sudden shutdown of the mobile phone.

Based on the terminal device shown in fig. 1, an embodiment of the present application provides a flowchart of a shutdown early warning method, as shown in fig. 2, a process of the method may be executed by the terminal device, and the method includes the following steps:

s201, the terminal equipment receives a first operation of a user.

Illustratively, the first operation may be a dialing operation of a dialing telephone application.

S202, responding to the first operation, the terminal equipment obtains the battery temperature and the battery real-time voltage of the terminal equipment, and estimates the current component after the function corresponding to the first operation is operated.

In the step, the terminal can acquire the temperature of the battery in real time through a temperature-sensitive resistor chip on the battery, and then acquire the real-time voltage of the battery through a battery voltage detection module of the chip. In addition, the current component after the function corresponding to the first operation is operated can be obtained by inquiring the corresponding relation table between the function corresponding to each operation and the estimated current component. The table of the correspondence between the functions corresponding to the respective operations and the estimated current components can be referred to the following table 3.

In a possible embodiment, if the terminal device determines that the current first operation is a high-risk behavior, the user may be timely reminded to stop the behavior. The terminal device stores a set comprising various high-risk behaviors, and the high-risk behaviors in the set are updated along with the use state of the terminal.

And S203, the terminal equipment determines the real-time internal resistance of the battery according to the battery temperature and the real-time voltage of the battery of the terminal equipment.

In this step, N corresponding relationships (specifically, see table 1 below) are pre-established in the terminal device, where each corresponding relationship includes a battery real-time voltage and a battery real-time resistance corresponding to the battery real-time voltage (specifically, see table 2 below). Therefore, the terminal device can determine a first corresponding relation corresponding to the battery temperature of the terminal device from the N corresponding relations according to the battery temperature of the terminal device; and then determining a battery real-time resistance corresponding to the battery real-time voltage of the terminal equipment from the first corresponding relation according to the battery real-time voltage of the terminal equipment.

And S204, the terminal equipment estimates the divided voltage of the terminal equipment after the function corresponding to the first operation runs according to the current component and the real-time internal resistance of the battery.

For example, the first operation may be a dialing operation of a dialing application, and the divided voltage of the function of the call of the mobile phone is 0.4V.

And S205, when the voltage difference value between the real-time voltage and the divided voltage of the battery is smaller than the shutdown voltage, the terminal equipment performs shutdown early warning.

Illustratively, when the real-time voltage of the battery is 2.6V, since the divided voltage is 0.4V, the voltage difference between the real-time voltage and the divided voltage of the battery is 2.2V, and the shutdown voltage is 2.3V, so that the mobile phone predicts that the battery voltage is lower than the shutdown voltage after the call function is executed, and the battery low-voltage protection mechanism is about to be started to cut off the power supply, so that the terminal device can perform shutdown early warning in time to prompt the user to suspend the operation, or search for other alternative operations.

In one possible implementation, after the terminal device performs shutdown early warning, an alternative second operation may be recommended to the user; and the function corresponding to the second operation is consistent with the function corresponding to the first operation, and the divided voltage after the function corresponding to the second operation is operated is smaller than the divided voltage after the function corresponding to the first operation is operated. The correspondence relationship between operations with the same function may be specifically referred to in table 4 below. Illustratively, as shown in (a) in fig. 3, a user is dialing through a phone application of a mobile phone, at this time, the mobile phone collects a current battery temperature of 50 ℃ and a battery real-time voltage of 2.6V, and then calculates a divided voltage of a call function to be 0.4V, since a voltage difference 2.2V between the battery real-time voltage and the divided voltage is less than a shutdown voltage of 2.3V, the mobile phone performs a shutdown warning, and recommends that the user switches to a WeChat voice call, as shown in a pop-up box 311 in (b) in fig. 3. Illustratively, as shown in FIG. 4, the user may select WeChat ^TM Voice call replacement cellA voice telephone.

In one possible implementation, before the method is performed, different OCV tables are associated with different temperature intervals, see table 1 below.

TABLE 1

The OCV table includes a battery voltage and a battery resistance corresponding to the battery voltage, and exemplarily, the relationship between the battery voltage and the battery resistance in the OCV table5 in table 1 is shown in table 2.

TABLE 2

It can also be seen from table 2 that when the mobile phone is low in power, the battery resistance is relatively large.

In addition, in this embodiment, a developer may perform power consumption tests (such as making a call, playing music, and the like) in various functional scenarios in advance to obtain current data in various functional scenarios, as shown in table 3 for example.

Furthermore, after executing S205, the terminal device may further update the current first operation as the high-risk behavior into the set of high-risk behaviors. For example, the user submits a high-risk operation pop-up prompt box alarm and recommends similar low-risk operations. Therefore, the terminal equipment can also inquire the high-risk behaviors in real time, and when the environment is changed and the internal resistance of the battery is greatly changed, the high-risk behaviors causing the shutdown of the equipment are increased more, a prompt box is popped up for alarming, so that the sudden shutdown is avoided.

In addition, the terminal device may be preset with a table of correspondence between various high-risk behaviors and alternative operations, as exemplarily shown in table 4.

TABLE 4

Type of scene	Alternative operations
		Making cellular network voice telephone	WeChat printing device ^TM Voice telephone
Make a video call to a cellular network	Typing WeChat ^TM Video telephone
		Playing music	Broadcast FM
......	.......
