The invention provides a formal switching voltage detection method, which comprises a main power supply, a standby power supply, an information collector and a load, and is characterized in that an MCU main control circuit is connected with the information collector and a power switch switching module, and the main power supply is connected with the load through the power switch switching module; the standby power supply is connected with the load through the power switch switching module, and the information collector is connected with the main power supply and the standby power supply. After the MCU main control circuit performs pre-switching voltage detection in the switching process of the main power supply and the power switch switching module, the MCU main control circuit performs formal switching voltage detection in the switching process of the standby power supply and the power switch switching module; according to the invention, the voltage change of the power supply in the switching process can be
