The invention provides an intelligent control system for a medical halogen shadowless lamp, wherein the intelligent control system belongs to the field of medical equipment. A control module is connected with a power supply management module, a real-time testing module, a driving adjustment module, a man-machine interaction module and a resetting read-write module. The man-machine interaction module comprises an LCD touch display screen, a button and an infrared remote control. The resetting read-write module comprises a downloading circuit, a resetting circuit, a watchdog circuit and a power-down protection circuit. The driving adjustment module comprises an MOS tube, a shadowless lamp main lamp and a shadowless lamp auxiliary lamp. The intelligent control system for the medical halogen shadowless lamp is based on an STM32 microprocessor and performs real-time testing on the working condition of the shadowless lamp. On the condition that the shadowless lamp main lamp fails, quick switching between the main lamp and the auxiliary lamp can be performed and brightness is kept unchanged; quick multistage adjustment is performed on the brightness of the shadowless lamp by means of PWM technology and the button; the current brightness grade and the working state of the shadowless lamp are displayed through the display screen; the control system supports a plurality of control modes such as the touch screen, the button and an infrared remote control; and good man-machine interaction is realized.
