Suppose that the monitor 200 monitors that the output voltage of one power supply suddenly decreases to 0V, and obtains the following information: 1, inquiring a single number to obtain a power supply model, and obtaining that the topological structure of a DC-DC converter part is a double-tube forward circuit; 2, research and development technicians obtain data monitored by the power supply in the monitoring machine 200 through field after-sales personnel, and know that key parameters such as the driving voltages of two MOS (metal oxide semiconductor) tubes in the double-tube forward circuit are normal except that the output voltage is suddenly reduced to 0; and 3, the backup power supply works normally. Therefore, the follow current circuit at the output end of the power supply can be presumed to be abnormal, and field after-sales personnel can record conditions such as the working environment, the humidity and the like of the power supply, so that the analysis efficiency is improved. Without this function, after-market personnel who may arrive at the site do not have the ability to analyze and measure the power supply and need to send back to the product home, which may take up to a week, but the customer site is not slow enough to give an immediate explanation to the customer. For another example, when the monitoring records that the input voltage is abnormal before the fault occurs, and the local power grid fluctuation is large when the power supply fault is confirmed, the problem of the power supply can be solved, and if the power supply is damaged due to the power grid fluctuation, the standby power supply can be replaced with a spare power supply with care.
