detailed description

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the specific embodiments set forth herein. Rather, the embodiments are provided to explain the principles of the invention and its practical application, thereby enabling others skilled in the art to understand the invention for various embodiments and with various modifications as are suited to particular intended uses.

An electronic device according to an embodiment of the present invention may be, for example, an audio player (such as a smart speaker), a smart phone, and the like. Fig. 1 shows a schematic diagram of modules of an electronic device according to an embodiment of the present invention.

Referring to FIG. 1 , an electronic device according to an embodiment of the present invention includes: a main control chip (eg, SoC (System-on-a-Chip) chip) 100 and a microcontroller unit (Microcontroller Unit; MCU) 200 . The Android system is installed in the main control chip 100 . It should be noted that the electronic device according to the embodiment of the present invention may also include other suitable types of components.

The main control chip 100 includes a first output interface (eg, General Purpose Input/Output (GPIO)) 110 and a restart interface 120 . The MCU 200 includes an input interface (eg, General Purpose Input Output (GPIO)) 210 and a second output interface (eg, General Purpose Input Output (GPIO)) 220 . The first output interface 110 of the main control chip 100 is connected with the input interface 210 of the MCU 200 . The restart interface 120 of the main control chip 100 is connected with the second output interface 220 of the MCU 200 .

The method for handling the abnormal working state of the Android system of an electronic device according to an embodiment of the present invention will be described in detail below with reference to FIG. 1 and FIG. 2 . Fig. 2 shows a flowchart of a method for processing an abnormal working state of an Android system of an electronic device according to an embodiment of the present invention.

1 and 2 together, in operation 310, the main control chip 100 sends the working state signal of the Android system installed in the main control chip 100 to the input interface 210 of the micro control unit 200 through its first output interface 110 .

Here, the working status signal of the Android system may include a normal working status signal or an abnormal working status signal.

The normal working status signal of the Android system is: initially output a high-level signal and output a low-level signal that lasts for a first predetermined time (for example, 1 second) every first predetermined time period (for example, 1 second) flat signal. In other words, the normal working state signal of the Android system is a level signal that periodically outputs a high-level signal and a low-level signal.

The abnormal working status signal of the Android system is: initially output a high-level signal and output the level of the high-level signal for the first predetermined time (for example, 1 second) every first predetermined time period (for example, 1 second) Signal. In other words, the abnormal working state signal of the Android system is a level signal that always outputs a high level signal.

In operation 320 , the MCU 200 recognizes whether the Android system is in an abnormal working state according to the working state signal of the Android system received by its input interface 210 .

Here, the specific method for the micro-control unit 200 to recognize that the Android system is in a normal working state is: if the input interface 210 of the micro-control unit 200 receives an input from the main control chip 100 within a second predetermined period of time (for example, within 10 seconds) At least one low-level signal provided by the first output interface 110, the MCU 200 recognizes that the Android system is in a normal working state.

And the specific method for the micro-control unit 200 to recognize that the Android system is in an abnormal working state is: if the input interface 210 of the micro-control unit 200 does not receive an input from the main control chip 100 within a second predetermined period of time (for example, within 10 seconds), If the low-level signal provided by the first output interface 110, the MCU 200 recognizes that the Android system is in an abnormal working state.

If the MCU 200 recognizes that the Android system is in an abnormal working state according to the working state signal of the Android system received by its input interface 210 , then proceed to operation 330 .

In operation 330 , the MCU 200 generates an Android system restart signal, and the MCU 200 sends the Android system restart signal to the restart interface 120 of the main control chip 100 through its second output interface 220 . Here, the Android system restart signal is a low-level signal. Afterwards, the main control chip 100 restarts the Android system according to the Android system restart signal received by its restart interface 120 .

If the MCU 200 recognizes that the Android system is in a normal working state according to the working state signal of the Android system received by its input interface 210 , proceed to operation 340 .

In operation 340 , the MCU 200 generates an Android system continuation signal, and the MCU 200 sends the Android system continuation signal to the restart interface 120 of the main control chip 100 through its second output interface 220 . Here, the Android system continuation signal is a high-level signal. Afterwards, the main control chip 100 makes the Android system continue to work according to the Android system continuation signal received by its restart interface 120 .

In summary, according to the embodiments of the present invention, the micro-control unit is used to monitor the working state of the Android system in the main control chip. When the Android system works abnormally, the micro-control unit controls the restart of the Android system, and realizes that the Android system is installed. The ability of the electronic device to automatically handle the abnormal operation of the Android system improves the user experience.
