Intelligent fast door controller

The utility model relates to the technical field of fast door controllers, and discloses an intelligent fast door controller which comprises a box body, and a box door is rotationally installed at the front end of the box body through a hinge. According to the intelligent fast door controller, a rectification unit, an MCU control unit, a protection unit and an inversion unit are arranged on a circuit board, a fast door motor is electrically connected with the MCU control unit and the protection unit, the rectification unit converts accessed 220 V alternating current into 310 V direct current, the protection unit drives an optical network and detects a voltage value, if the voltage value changes, a corresponding driving signal is locked, and if the voltage value changes, the inversion unit drives the fast door motor to rotate. The inverter unit inverts 310 V direct current into alternating current with variable current frequency to close a fast door motor, intelligent control over the fast door is achieved, a
