Description of the Invention: [Technical Leading Technology of the Invention] The present invention relates to a method for recording abnormal information of an electronic cracking machine and an electronic device therefor. [Prior Art] A watchdog timer is a device for improving the reliability of an electronic device based on a timer principle, and the electronic device refers to a computer or a palm-type electronic device (eg, a mobile phone), using a s timer The circuit's timing output is connected to the re-station of the ❿ circuit. The program resets the timer within the set time range (commonly known as “feeding the dog”). Therefore, when the program works normally, the timer can not overflow, and the re-determination cannot be generated. signal. If the program fails and the watchdog is not reset within the timeout period, the watchdog timer overflow causes a re-signal and restarts the system to return to normal operation. Most and commonly used watchdog timers are placed in an embedded system. The watchdog timer can also trigger and activate the control system to bring the control system into a safe state, such as turning off the motor and turning off the high voltage output. , and shut down other potentially dangerous subsystems (Subsystem) until the system is faulty and the fault is resolved. For example, a watchdog timer consists of an X bit (bit) timer and a y MHz (million Hz) frequency signal. Thus, if the timer is not cleared within 2,/1, 6 seconds, the watchdog timer will issue a reset, reset or Shutdown signal to the system.目刚'Installing the watchdog timer in the electronic device (such as PC, Personal Computer, PC) can make the PC reset the CPU when the abnormal situation 5 201007444 (such as when the machine is down), ie · clear All the CPUs are in the program, so that the PC can resume the operation (4). "When an abnormal situation occurs in the PC, the information on the abnormal situation is not saved, so the user cannot understand the cause of the abnormal situation.

The electronic device 1 mainly includes a watchdog timer (Watchd〇g timer) 2 reset controller 3, a general purpose input output (gpio: General Purpose Input Output) chip 4 and a central processing unit (Central Pr〇cessing ❹ Unit) 5. The watchdog timer 2 is connected to a reset controller 3, which is also connected to a GPIO wafer 4, which is connected to a cpu5. The watchdog timer 2 is configured to determine whether the timing reaches the specified value. If the timing reaches the specified value, the watchdog timer 2 generates a trigger command, and sends the trigger command to the reset controller 3 to cause the reset control. The device 3 generates a reset nickname. The reset signal is used to clear the running program in the CPU 5, so that the running program in the CPU 5 ends immediately. Specifically, in general, the watchdog timer 2 is counted in time reciprocal (for example, every time from the first 〇〇201007444 seconds to 0 seconds), assuming that the specified value set by the watchdog timer 2 is When the trigger command is generated at the 0th second, the watchdog timer 2 generates a trigger command when the time counts down to the second second, and the second second is the specified value. The reset controller 3 is configured to receive the trigger command, determine the source of the trigger command, to confirm whether it is from the watchdog timer 2, and generate a reset signal to clear the running program in the CPU 5. . The trigger command may come from the watchdog trigger 2, or may be from other devices connected to the reset controller 3. For example, when the user restarts the electronic device 1, the reset button can be pressed (usually called: Reset). Press the button ' to trigger the reset controller 3 to generate a reset signal to clear the running mode in the CPU 5 and then restart the operating system. The way to determine the source of the trigger command is judged by the frequency of the trigger command. For example, the frequency generated by the watchdog timer 2 is within a certain range. If the frequency of the trigger command is within the range, it means that the watchdog timing is The command signal generated by the device 2. The GHO chip is used to reset the controller 3 to confirm that the trigger command is from the watchdog timer 2 when the GPI0 chip recording electronic device 1 is running and the abnormal information of the crash occurs and save it to the storage medium. The storage medium may be a flash memory, a micro hard disk, and any suitable medium capable of storing data. The GPI0 chip simplifies I/O port expansion using industry standards such as I2C, SMBus or SPI interfaces, when the microcontroller, chipset does not have enough I/O淳 or when the system requires remote serial communication or When controlled, the GPIO chip provides additional control and monitoring. In the preferred embodiment, the GPIO chip mainly records the abnormal information of the electronic device 1 when it is running. The abnormal information includes the reason for the crash 8 201007444 . ‘, as shown in FIG. 2, is a flow chart of a preferred embodiment of the method for recording electronic device crash abnormality information of the present invention. ο Step S1G 'First' The watchdog timer 2 is lying on the devaluation. If the specified value is reached, the watchdog material ^ 2 generates a touch and sends a trigger command to the reset controller 3, causing the reset (four) device 曰 3 to generate a reset signal. The reset letter is for clearing the running process in the CPU 5 so that the running program of the CPU 5 t ends immediately. If the watchdog timer 2 or 2 does not: the specified value is reached, the judgment step is repeated. Specifically, ^, see the dog material ϋ 2 is based on the time _ number, == 鸠 to leap seconds), assuming that the watchdog timer 2 = value 疋 generates a trigger command in the G seconds, then the gate When the timer counts down to the second second, the production value is the specified value. The trigger command is generated and the second command is # 詈^ When the watchdog timer 2 reaches the specified value, the control control 3 receives the trigger command. Step S12 f sets the controller 3 to determine the trigger command ## to confirm whether it is from the source of the doorkeeper. Step S13, if the trigger command is not

The trigger command may be from the watchdog trigger 2, or may be from a device connected to the Z controller 3. For example, when the user restarts the electronic device 1, the user may press the restart button (generally called ^). 3B ^ . , 〇σ KeSet button), you can directly trigger the reset control to generate a reset signal to clear the program in CPU5, and then restart the operating system. The party that determines the source of the trigger command is judged by the frequency of the trigger command. For example, the frequency of the watchdog timer 2 is within a certain range, and if the frequency of the trigger command is within the range ^ It is the command signal generated by the watchdog timer 2. In step S13, when the reset controller 3 confirms that "two from the watchdog timer 2, the GPK" wafer 4 records the abnormality information of the occurrence of the crash when the electronic device i is running and saves it to the storage medium. The storage medium can be a flash memory, a micro hard disk, and any suitable medium capable of storing data. The GPIO chip 4 simplifies I/O using industry standards such as I2C, SMBus or SPI interfaces. The expansion of the port provides additional control and monitoring functions when the microcontroller, chipset does not have sufficient I/O, or when the system requires remote serial communication or control. In the preferred embodiment, The GPIO chip mainly records the abnormal information of the abnormal condition of the electronic device 1 during operation. The abnormality information includes the cause of the crash, and the time of the crash occurs. ❹ Step S14, the reset controller 3 generates a reset signal, And the reset "number is sent to the CPU 5 ' to clear the running program in the CPU 5" causes the electronic device 1 to restart the operating system. Specifically, assuming that the ‘condition of the crash occurs, the electronic device 1 cannot operate normally, at this time, all running programs in the CPU 5 are cleared', and even if the running program ends immediately, the operating system is restarted.
