Description

Electronic device with sleep function and method for waking up electronic device

The present invention relates to an electronic device having a sleep function, and more particularly to an electronic device capable of instantly detecting a battery state in a sleep mode and a method of waking up the electronic device.

In order to save energy, the electronic device generally sets two working states: a working mode and a sleep mode. When the electronic device is in the working mode, the relevant parameters (such as power, temperature, etc.) of the currently powered battery are instantly detected by the central processing unit. When the central processor detects that an abnormality occurs in the current relevant parameters of the battery, the central processor controls to turn off the electronic device or perform other corresponding protection measures. However, when the electronic device is in sleep mode, that is, the central processing unit is in a sleep or off state, the central processing unit cannot immediately detect the battery status. Therefore, when the battery is abnormal, the central processor cannot detect it in time to save the data and immediately shut down or perform other protection measures.

In view of this, it is necessary to provide an electronic device that can instantly detect the state of the battery in the sleep mode.

The present invention also provides a method of waking up an electronic device having a sleep function.

An electronic device with a sleep function for detecting a power battery abnormal state in time and waking up or restarting a central processor of the electronic device. The electronic device includes a central processing unit and a monitoring unit. The monitoring unit includes: a detecting module, configured to detect related parameters of the power supply battery of the electronic device; and a comparison determining module, configured to compare the related parameter with a preset parameter interval and determine the related parameter Whether it belongs to the preset parameter interval; the storage module is configured to pre-store the preset parameter interval; the signal generating module is configured to generate a control signal to wake up or restart when determining that the relevant parameter does not belong to the preset parameter interval CPU. The battery abnormal state protection function is executed after the central processor is awake or restarted and is in a working state.

1 is an embodiment of the present invention for instantly detecting battery status in a sleep mode according to an embodiment of the present invention; Sub-device block diagram.

2 is a flow chart of a method for waking up an electronic device in a sleep mode according to an embodiment of the present invention.

The present invention will be described in detail below with reference to the embodiments and the accompanying drawings.

Referring to FIG. 1, the electronic device 10 includes a central processing unit 21 and a monitoring unit 23 for monitoring battery status. When the electronic device 10 enters the sleep mode, the monitoring unit 23 detects relevant parameters of the power supply battery (not shown) of the electronic device 10. If the monitoring unit 23 detects that an abnormality occurs in the battery related parameter, the monitoring unit 23 generates a control signal to wake up or restart the central processing unit 21, and timely takes corresponding protection measures such as shutting down or cutting off the battery to supply power to the electronic device 10. . In the present embodiment, the relevant parameter refers to a parameter such as a battery temperature, a current output voltage value of the battery, or a current value.

The monitoring unit 23 includes a detection module 231, a comparison determination module 231, a storage module 233, and a signal generation module 234.

The detecting module 231 is configured to detect related parameters of the power supply battery of the electronic device 10. In this embodiment, the detection module 231 includes at least one sensor for detecting battery related parameters, such as a temperature sensor, a voltage sensor, a current sensor, and the like.

The comparison determining module 231 is configured to compare the related parameter with a preset parameter interval and determine whether the related parameter belongs to a preset parameter interval. The preset parameter interval includes a temperature amplitude interval, a battery voltage amplitude interval, or a current amplitude interval.

The storage module 233 is configured to store the preset parameter interval. In this embodiment, for example, the storage module 233 stores the maximum allowable temperature value, the minimum temperature value, and the most One or more temperature values between the large temperature value and the minimum temperature value, the one or more temperature values dividing the range between the maximum temperature value and the minimum temperature value into a plurality of temperature amplitude intervals. The preset parameter interval is preset in the storage module 233 by a manufacturer of the electronic device.

The signal generation module 234 is configured to generate a control signal to wake up or restart the central processing unit 21 when it is determined that the relevant parameter does not belong to the preset parameter interval. After the central processor 21 wakes up or restarts and is in the working state, performs protection measures such as battery over temperature and overvoltage, such as issuing an alarm prompt or controlling the electronic device 10 to shut down, or controlling the electronic device 10 to shut down after issuing an alarm prompt. In the present embodiment, after the central processing unit 21 is woken up or restarted, the central processing unit 21 also compares the battery voltage with the power-on voltage of the electronic device 10. When the central processing unit 21 determines that the battery voltage is lower than the startup voltage, the electronic device 10 is immediately turned off.

Please refer to FIG. 2 , which illustrates the method for detecting the battery parameters and waking up the electronic device 10 by the electronic device 10 of the present invention. The electronic device includes a central processing unit 21 and a monitoring unit 23.

In step S31, the current relevant parameters of the power supply battery of the electronic device are detected.

In step S32, comparing the relevant parameter with the preset parameter interval and determining whether the related parameter belongs to the preset parameter interval. If yes, the process of step S21 is continuously performed; if not, the process proceeds to the next step.

In step S33, a control signal is generated to wake up or restart the central processor.

In step S34, the central processor performs a battery abnormality protection function. In this embodiment, the central processing unit 21 performs protection measures such as battery over temperature and overvoltage, such as issuing an alarm prompt or controlling the electronic device 10 to shut down, or issuing an alarm prompt to control the electronic device. Set 10 to shut down.

Step S35, determining whether the battery voltage is less than the startup voltage? If no, it will not work; if yes, proceed to the next step.

In step S36, the control turns off the electronic device.

By using the above-described electronic device or method for detecting battery parameters, when the electronic device 10 is in the sleep mode, that is, its central processing unit 21 is in a sleep-off state. The monitoring unit 23 detects the battery related parameters in real time, and wakes up or restarts the central processing unit 21 when the battery parameters are abnormal, so that corresponding protection measures can be taken in time. At the same time, when the electronic device 10 is in the working mode, the central processing unit 21 does not need to monitor the condition of its power supply battery, thereby saving the resource utilization of the central processing unit 21.

It should be understood by those skilled in the art that the above embodiments are only intended to illustrate the invention, and are not intended to limit the invention, as long as it is within the spirit of the invention. Changes and modifications are intended to fall within the scope of the invention.
