Detailed Description
The core of the application is to provide a monitoring method, a monitoring system, a monitoring device and an electronic device, an independent processor is used for detecting the working state of a control chip, even if the control chip is completely stuck, the PMIC can be controlled to be powered off and powered on again through the processor, and the function of resetting the control chip is achieved.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1 and fig. 2, fig. 1 is a schematic flow chart of a monitoring method provided in the present application, and fig. 2 is a schematic connection diagram of a processor provided in the present application. The method is used for a processor with one end connected with a control chip in electronic equipment and the other end connected with a PMIC, and comprises the following steps:
s11: determining whether a detection signal sent by a control chip according to a preset rule is received;
specifically, in the present application, an independent processor is disposed in the electronic device, and the processor communicates with a control chip in the electronic device and a PMIC that supplies power to the control chip, and detects an operating state of the control chip, at this time, even if the control chip is locked, the independent processor may communicate with the PMIC, so that the PMIC controls the control chip to be powered off and powered on again.
Specifically, the control chip sends a detection signal to the processor according to a preset rule, and when the control chip works normally, the processor receives the detection signal from the control chip according to the preset rule. However, when the control chip works abnormally (for example, the control chip works unstably or the control chip is stuck), the detection signal output by the control chip to the processor is also unstable, (where the instability may be that the control chip does not send the detection signal to the processor according to a preset rule, that is, the detection signal received by the processor is irregular, or the control chip does not send the detection signal to the processor any more, that is, the processor cannot receive the detection signal). At this time, as long as the processor detects that the regular detection signal is not received, the processor judges that the control chip works abnormally, and the monitoring function of the control chip can be realized.
It should be noted that the preset rule in the present application is only required to follow a certain traceable rule, and may be to send the same detection signal according to a fixed period, or to send different detection signals according to a certain fixed rule, which is not limited herein.
Further, the detection signal in the present application may be a fixed character or a character segment, or may be a fixed level signal, and the present application is not limited thereto.
Further, the control chip in the present application may be, but is not limited to, an MCU.
S12: if not, the control chip is judged to be abnormal, and a reset signal is sent to the PMIC, so that the PMIC controls the control chip to be powered down and powered up again.
Specifically, when the processor does not receive a detection signal with a preset rule, it is determined that the control chip cannot send the detection signal according to the preset rule, that is, it is determined that the control chip is in an abnormal state, that is, the control chip needs to be restarted, and at this time, the processor sends a reset signal to the PMIC, so that the PMIC controls the control chip to be powered down and powered up again, and the reset of the control chip is completed.
It should be further noted that, in the present application, the reason for the abnormal operation of the control chip may be that the control chip finds that its operation is unstable or it crashes through its own detection (for example, the reason that the memory is not controllable or the data is abnormal). The mode in this application and the mode that uses the watchdog to monitor control chip and compare, the monitoring mode in this application is more reliable.
Specifically, the mode of monitoring the control chip by the watchdog is specifically described as follows: and starting the watchdog module after the initialization of the control chip is finished, wherein the watchdog module has a counting function and counts down to 0 from N, and when the count reaches 0, the control chip is judged to be abnormal, and the control chip is reset. Therefore, the count value is reset to N at regular time when the control chip is abnormal. Specifically, assuming that 3 minutes is required for counting down from N to 0, when the control chip is normal, the count value may be reset to N every 2 minutes to indicate the normal state of the control chip. When the control chip is abnormal, the control chip cannot reset the count value to N at regular time, and at the moment, the watchdog module continuously counts N down to 0, so that the reset of the control chip is realized. However, when the watchdog module is abnormal, the counting abnormality may occur, which may cause the reset abnormality of the control chip. It follows that the approach in the present application is more reliable to implement than the watchdog approach.
In summary, the monitoring method in the present application can use an independent processor to detect the operating state of the control chip, and even if the control chip is completely stuck, the PMIC can be powered off and powered on again through the processor, so as to achieve the function of resetting the control chip

The first preset duration may be, but is not limited to, 8ms, and the second preset duration may be, but is not limited to, 2 ms. One period of the preset level signal is just 10ms, at this time, if the period of the level signal monitored by the processor is just 10ms, and 8ms is low level, the control chip is judged to work normally, a correct detection signal can be output, at this time, the processor does not send a reset signal to the PMIC, and the control chip does not reset or reset. Otherwise, the control chip resets.
