The present invention relates to an apparatus and a method for warning of the abnormal opening and closing operation of a plastic greenhouse. According to the present invention, the apparatus comprises: a motor (130) to open and close the plastic greenhouse or an insulation cover a current detection unit (140) detecting the operating current of the motor during the operation of the motor (130) a control unit (120) operating the motor (130) by checking predetermined conditions, and recognizing that there is an abnormality in the opening and closing rate of the plastic greenhouse or insulation cover when it is verified that the value of the current detected in the current detection unit (140) is greater than or equal to a predetermined current value, followed by stopping the operation of the motor (130) and an abnormality occurrence notifying unit (150) generating an alarm by the control unit (120) or notifying a crop cultivator of the abnormality by a communication method when the control unit (120) recognizes that there is the abnormality in the opening and closing rate of the plastic greenhouse or insulation cover. According to the present invention, the apparatus detects the operating current of the motor, thereby recognizing that a winding rate changes according to a winding position as foreign substances get stuck during the opening and closing operation of the plastic greenhouse or insulation cover, and stops the operation of the motor. Accordingly, damage on the plastic greenhouse or insulation cover is prevented. Furthermore, a crop cultivator or an administrator is notified of abnormality occurrence by an alarm or a communication method so as to quickly take a measure so the economic loss of the crop cultivator can be prevented.COPYRIGHT KIPO 2016본 발명은 비닐하우스의 개폐 이상 경보 장치 및 방법에 관한 것으로, 본 발명은 비닐하우스 또는 보온덮개의 개폐를 위한 모터(130)와, 상기 모터(130)의 작동 시에 그 모터의 동작전류를 검출하는 전류검출부(140)와, 미리 설정된 조건을 확인하여 상기 모터(130)를 작동시키며 상기 전류검출부(140)에서 검출한 전류가 미리 설정된 전류치 이상으로 판명되면 상기 비닐하우스 또는
