Power failure monitoring device and power failure monitoring method

A power failure monitoring device comprising:

• an electronic device;
• and
• a console, wherein
• the electronic device comprises a main board, the main board comprises a programmable logic device and a baseboard management controller coupled to the programmable logic device, and
• the console is coupled to the main board and adapted to obtain power failure information in the electronic device, and the console analyzes a power supply condition of the electronic device according to the obtained power failure information;
• the programmable logic device is configured to:
• output a power supply enable signal, the power supply enable signal is used to instruct at least one power supply on the mainboard to power on,
• start counting on a counter,
• use, before a current reading of the counter reaches a preset value, a falling edge of a power supply status indication signal, for each power supply, to determine whether a first abnormal power supply status indication signal exists,
• output a first read notification signal according to the first abnormal power supply status indication signal when the first abnormal power supply status indication signal exists, and
• the baseboard management controller reads the first abnormal power supply status indication signal according to the first read notification signal, and generates a corresponding power supply status log;
• determine, after the current reading of the counter reaches the preset value, whether a second abnormal power supply status indication signal exists according to the power supply status indication signal, and
• output, in response that the second abnormal power supply status indication signal exists, a second read notification signal according to the second abnormal power supply status indication signal, and the baseboard management controller reads the second abnormal power supply status indication signal according to the second read notification signal and generates a corresponding power supply status log.
