technical field

The present invention relates to the technical field of mobile terminals, in particular to a method and device for automatically restarting a terminal after it crashes.

With the emergence of smart APPs, more and more various APPs are installed on users' mobile terminals. At the same time, more and more users are more accustomed to running multiple APPs on the mobile terminal at the same time, which leads to a higher frequency of mobile terminal operation, followed by a higher and higher probability of the mobile terminal crashing.

When the mobile terminal crashes, because the mobile terminal system is stuck in a certain process, the current of the mobile terminal system continues, causing the temperature of the mobile terminal body to continue to rise, resulting in a sharp decline in the battery life of the mobile terminal; and if the user cannot If it is found that the mobile terminal is down in time, it will affect the normal communication of the user, such as being unable to receive incoming calls.

Detailed ways

In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only the technical solutions of the present invention. Some, but not all, embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

Embodiment one

Referring to FIG. 1 , FIG. 1 is a flowchart of a method for automatically restarting a terminal after a crash according to the present invention. A method for automatically restarting a terminal after it crashes, comprising:

S101. Obtain a terminal temperature value in real time.

In step S101, there are many ways to obtain the terminal temperature value, for example, obtain through a temperature sensor.

S102. If the terminal temperature value is greater than or equal to a preset shutdown temperature value, turn off the terminal power supply switch.

In step S102, the preset dead-time temperature value is higher than the maximum temperature when the terminal is in normal operation. Compare the terminal temperature value obtained in S101 with the preset dead-time temperature value, and if the terminal temperature value obtained in S101 is greater than or equal to the preset dead-time temperature value, turn off the terminal power supply switch.

There are many factors that cause the terminal to crash. A common cause of the terminal crash is: when the terminal operates at a high frequency, due to the design of the power supply PDN (including the chip level and the PCB wiring part of the main board), the terminal system runs at a relatively high frequency. When it is high, the power supply fluctuates greatly, and when the power supply voltage is lower than the rated voltage, the terminal will crash. At this time, the operating frequency of the terminal system is relatively high, and the corresponding current and voltage are both relatively high. At this time, the heat generated by the terminal will be higher than the normal temperature of the terminal. The present invention uses temperature as the condition for judging whether the terminal is dead or not. Once the terminal temperature value is greater than or equal to the preset dead temperature value, it will automatically power off and restart, which can solve the problem of terminal dead in a timely and accurate manner.

S103. After the terminal power supply switch is turned off, if the acquired terminal temperature value is lower than the preset shutdown temperature value, turn on the terminal power supply switch and trigger the terminal to start up.

In step S103, after the terminal power supply switch is turned off, the terminal temperature drops slowly. The present invention obtains the terminal temperature value in real time. When the terminal temperature drops below the preset shutdown temperature value, the terminal system considers that the shutdown state has been reached. When unlocking, the control unit of the terminal controls to turn on the power supply switch of the terminal, and at the same time controls to send a pulse signal to trigger the terminal to turn on.

The present invention uses the terminal temperature value as the condition for judging the terminal crash, and can timely and accurately discover the terminal crash state; once the terminal crash is found, the terminal power supply switch is immediately disconnected to alleviate the temperature rise when the terminal crashes; the terminal power supply switch is disconnected Afterwards, the terminal temperature drops slowly. When the terminal temperature drops below the preset shutdown temperature value, the terminal power supply switch is turned on and the terminal is triggered to start up, so as to achieve the purpose of automatic restart after the terminal crashes; the present invention does not require manual intervention to connect With the input, it is possible to accurately and timely identify terminal crashes and realize automatic restart of the terminal crashes, thereby preventing users from missing important communications due to unaware terminal crashes.

Embodiment two

Referring to FIG. 2 , FIG. 2 is another flow chart of a method for automatically restarting a terminal after it crashes according to the present invention. A method for automatically restarting a terminal after it crashes, comprising:

S201. Presetting multiple shutdown temperature values. Presetting a plurality of dead-time temperature values specifically includes: dividing the ambient temperature value into several different temperature value intervals; and setting a different dead-time temperature value for each of the temperature value intervals.

In step S201, since a single dead-time temperature value cannot accurately and reliably identify the terminal dead-time state under multiple environmental factors, in order to solve this problem, this embodiment proposes to preset multiple dead-time temperature values, and the preset multiple dead-time temperature values It is related to the external environment temperature value, the greater the external environment temperature value, the greater the preset shutdown temperature value, that is, the preset shutdown temperature value is positively correlated with the external environment temperature value.

Presetting multiple dead-time temperature values is specifically: dividing the ambient temperature value into several different temperature value intervals, and setting different dead-time temperature values for each of the temperature value intervals; for example, dividing the ambient temperature value into 3 different Temperature value range: below 0°C, 0°C-25°C and above 25°C, set the shutdown temperature value to 20°C for the "below 0°C" temperature range, and set the shutdown temperature value to 45 for the "0°C-25°C" temperature range °C, for the "above 25 °C" temperature range, set the shutdown temperature value to 50 °C.

S202. Obtain an ambient temperature value, obtain a relative temperature value of terminal shutdown, and obtain a terminal temperature value by summing the ambient temperature value and the relative temperature value of terminal shutdown.

In step S202, the ambient temperature value is the temperature value of the external environment where the terminal is located;

The meaning of the relative temperature of the terminal crash is: when the power of the terminal is fixed, the heat generated by the power is certain, and the temperature generated by a certain amount of heat in the terminal body is constant, and the temperature generated is the terminal crash. relative temperature. For example, assuming that the dead voltage of the terminal is 4V and the dead current is 1.5A, then the dead power at this time is 6W, and the temperature rise generated by the power of 6W in the terminal body is 20°C, that is, the relative temperature of the dead end is 20°C.

The terminal temperature value is obtained by summing the ambient temperature value and the relative temperature value of the terminal shutdown, for example, the ambient temperature value is 0°C, and the relative temperature of the terminal shutdown is 20°C, then the terminal temperature value is 20°C; the ambient temperature value If the relative temperature of terminal shutdown is 25°C, the terminal temperature value is 45°C; if the ambient temperature is 30°C, the relative temperature of terminal shutdown is 20°C, then the terminal temperature value is 50°C.

In the present invention, the heat generated by the power when the terminal is down is mainly concentrated inside the terminal, and it takes a very short time to judge whether the terminal is down; It can be ignored; this embodiment takes this as a premise when calculating the terminal temperature value.

S203. Based on the acquired ambient temperature value, determine a preset shutdown temperature value from a plurality of preset shutdown temperature values.

In step S203, determining a preset dead-time temperature value from a plurality of preset dead-time temperature values based on the obtained ambient temperature value specifically includes: determining the temperature value range where the ambient temperature value obtained in S202 is located, and determining a temperature range based on the temperature The corresponding relationship between the value range and the dead-time temperature value determines the dead-time temperature value corresponding to the temperature value range; the temperature value range and the corresponding relationship between the temperature value range and the dead-time temperature value are determined in S201. For example, as described in S201: Divide the ambient temperature value into three different temperature ranges: below 0°C, 0°C-25°C and above 25°C, and set the shutdown temperature value to 20 for the temperature range "below 0°C". °C, set the dead-time temperature value to 45°C for the "0°C-25°C" temperature range, and set the dead-time temperature value to 50°C for the "above 25°C" temperature range, expressed in a table:

Temperature range Crash temperature value Below 0℃ 20°C 0℃-25℃ 45°C Above 25℃ 50℃

If the ambient temperature value obtained in S202 is 10°C, the process of realizing this step S203 is: determine the temperature value interval of 10°C as "0°C-25°C", and from the corresponding relationship between the temperature value interval and the shutdown temperature value, It can be determined that the dead-time temperature value corresponding to "0°C-25°C" is 45°C. That is, when the ambient temperature value is 10°C, the preset shutdown temperature value used to determine the terminal shutdown is 45°C.

S204. If the terminal temperature value is greater than or equal to a preset shutdown temperature value, turn off the terminal power supply switch.

The preset dead-time temperature value in step S204 is the dead-time temperature value determined in S203. Get the terminal temperature value in S202, determine the shutdown temperature value in S203, compare the terminal temperature value obtained in S202 with the shutdown temperature value determined in S203 in S204, if the terminal temperature value obtained in S202 is greater than or equal to the shutdown temperature value determined in S203, then disconnect Terminal power switch.

S205. After the terminal power supply switch is turned off, if the acquired terminal temperature value is lower than the preset shutdown temperature value, turn on the terminal power supply switch and trigger the terminal to start up.

In step S205, after the terminal power supply switch is turned off, the terminal temperature drops slowly. When the terminal temperature drops below the dead-time temperature value determined in S203, the terminal system considers that the dead-time state has been unlocked, and then turns on the terminal power supply switch, and at the same time Send a pulse signal to trigger the terminal to start up, so as to realize the automatic restart after the terminal crashes.

This embodiment solves the problem that a single dead-time temperature value cannot accurately and reliably identify terminal dead-time under different ambient temperatures. For this purpose, multiple dead-time temperature values are preset and determined from multiple preset dead-time temperature values according to the external environment temperature value. A most suitable crash temperature value, in order to achieve timely and accurate identification of terminal crashes and timely automatic restart of the terminal crashes under different ambient temperatures; A preferred embodiment of the method described above.
