This application relates to the field of power switching technology, and discloses a firmware-controlled peripheral interface power adaptive switching system and method. The method involves: upon detecting a peripheral connection, providing a basic power supply voltage to the peripheral and initializing the UART serial communication interface; sending a model query command to the peripheral and extracting the peripheral model identifier string from the response frame to generate a relay control command; controlling a Darlington transistor array driver chip to drive the coil of a double-pole double-throw relay, switching the connection state of the relay's common terminal contact, and reading the voltage and current measurements of the peripheral; calculating the peripheral's power value, and encapsulating the power value and power supply mode status into a status data packet and transmitting it to the peripheral management software. This application transforms power supply configuration from hardware mechanical operation to firmware intelligent control, realizing plug-and-play, zero-error configuration, and visual management of peripheral power supply, reducing production costs and maintenance difficulty, and improving the intelligence level of peripheral interface power management.
