The invention discloses an anti-locked-rotor control system for an automatic ventilation film reeler of a solar greenhouse. The control system comprises a rolling blind machine (3), a film reeler (4) and a control box (6), wherein a control board is arranged in the control box (6) and electrically connected with the rolling blind machine (3), the film reeler (4), a ventilation switch arranged in a ventilation opening (9), a temperature sensor (7) arranged in the greenhouse, a photoelectric switch group (12) for detecting the position of a heat preservation quilt and a photoelectric switch group (2) for detecting the position of a film reeling shaft. The photoelectric switch groups are utilized for locating the heat preservation quilt and the film reeler separately, so that control on correct working order of the rolling blind machine and the film reeler is achieved. The invention further discloses an algorithm of the anti-locked-rotor control system for the automatic ventilation film reeler of the solar greenhouse and algorithm. Rolling and falling functions are completed through the rolling blind machine and the film reeler according to preset time and parameters, the reasonable order of blind rolling and ventilation control is ensured, and the burnout phenomenon, caused by over-high locked-rotor current, of the film reeler and a corresponding control circuit is avoided.
