The method for detecting an abnormal state of an electronic system according to claim 1, wherein after the system health management unit performs adjustment processing according to the chip abnormal information, if the board card is still abnormal, the system health management unit cuts off power supply to the abnormal board card and reports the abnormal information to an equipment administrator, specifically comprising:
the system health management unit receives the abnormal information sent by the chip, adjusts and processes the abnormal information and sends a health detection request to the board card again;
if the board card is detected to be abnormal, the system health management unit cuts off the power supply of the abnormal board card and reports the abnormal information to an equipment administrator through the SPI interface.
6. The method as claimed in claim 5, wherein after the system health management unit receives the abnormal information sent by the chip and adjusts the abnormal information, if the current voltage is too low, the current is too high, or the temperature is too high, the active frequency reduction operation of the system is performed.
