Detailed ways

FIG. 1 is a system diagram showing an application program management system according to an embodiment of the present invention.

The application program management system 100 according to the embodiment of the present invention includes: a computer system 110 and a second processor 120 . Wherein, the computer system 110 includes a first processor 112 for executing an application program 111 . It should be noted that the application program 111 is a specific application program corresponding to different operation modes of the computer system 110 . The computer system 110 can operate in a computer mode (the computer is operated by a complete operating system) and an entertainment mode (the computer is operated by a simplified operating system), wherein the entertainment mode can include multiple sub-modes, such as music mode, movie mode, TV mode, radio mode, and photo mode, etc. In this case, the application program 111 may be any program executed in the computer mode, or a specific application program corresponding to different sub-modes in the entertainment mode, and execute corresponding functions.

The second processor may be an external processor connected to the computer system 110 . The second processor includes: a monitoring module 121 , such as a watchdog program, configured to monitor the running status of the application program 111 in the computer system 110 . When the running state of the application program is abnormal, the monitoring module 121 will send a control signal to the power supply circuit (not shown in the figure) of the computer system through the second processor 120, so that the computer system 110 is restarted, and the second A processor 112 re-executes the application program 111 .

It should be noted that the monitoring module 121 can monitor the running status of the application program 111 in the computer system 110 in two ways. The first way is to write a program in the application program 111 to transmit the survival signal to the monitoring module 121 of the second processor 120 every first predetermined time interval. If the monitoring module 121 does not receive the survival signal transmitted by the application program 111 within the second predetermined time, it determines that the running state of the application program 111 is abnormal.

In addition, the second way is to transmit the confirmation signal to the application program 111 of the computer system 110 through the monitoring module 121 at every first predetermined time interval, and a program is also written in the application program 111, when the application program 111 receives When the monitoring module 121 sends the confirmation signal, the application program 111 will send the survival signal back to the monitoring module 121 according to the confirmation signal. In this case, if the monitoring module 121 does not receive the survival signal transmitted by the application program 111 within the second predetermined time, it determines that the running state of the application program 111 is abnormal.

FIG. 2 is a flowchart illustrating an application program management method according to an embodiment of the present invention.

First, in step S201 , the first processor 112 of the computer system 110 executes the application program 111 . Then, in step S202 , the monitoring module 121 of the second processor 120 monitors the running state of the application program 111 . At this time, if there is no abnormality in the running state of the application program ("No" in step S203), the process returns to step S202, and the monitoring module 121 continues to monitor the running state of the application program 111.

And when the running state of the application program is abnormal (“Yes” in step S203 ), in step S204 , the monitoring module 121 sends a control signal to the power supply circuit of the computer system to restart the computer system 110 . Finally, in step S205, the application program 111 is re-executed by the first processor.

Similarly, the running status of the application program 111 in the computer system 110 can be monitored in two ways. The first way is to write a program in the application program 111 to transmit the survival signal to the monitoring module 121 of the second processor 120 every first predetermined time interval. If the monitoring module 121 does not receive the survival signal transmitted by the application program 111 within the second predetermined time, it determines that the running state of the application program 111 is abnormal.

In addition, the second way is to transmit the confirmation signal to the application program 111 of the computer system 110 at every first predetermined time interval through the monitoring module 121, and a program is also written in the application program 111, when the application program 111 receives When receiving the confirmation signal sent by the monitoring module 121, the application program 111 will send the survival signal back to the monitoring module 121 according to the confirmation signal. At this time, if the monitoring module 121 does not receive the survival signal transmitted by the application program 111 within the second predetermined time, it determines that the running state of the application program 111 is abnormal.

Therefore, according to the application program management system and method provided by the present invention, the running state of the application program in the computer system can be monitored through the external processor, so that when the application program runs abnormally, the computer system is automatically restarted and re-executed application.

Although the invention has been disclosed through preferred embodiments, these preferred embodiments are not intended to limit the invention. Those skilled in the art should understand that some changes and modifications can be made to the present invention without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined by the appended claims .
