The present invention provides a control device of opening and closing instruments for plastic greenhouse, which enables to separately or collectively open and close the opening and closing instruments installed in each plastic greenhouse by using one control box, so that an operator does not need to open and close plastic greenhouses separately, and conveniently and rapidly opens and closes the plastic greenhouses. Furthermore, the control device of opening and closing instruments for plastic greenhouses can prevent unnecessary electricity consumption. The present invention relates to the control device of opening and closing instruments for plastic greenhouses, which is composed to control the operation for opening and closing the plastic installed in plastic greenhouses according to the operation of motors for opening and closing instruments, wherein the motors for opening and closing instrument are installed in multiple plastic greenhouses. The control device of opening and closing instruments for plastic greenhouses comprises a brake switch for supplying or blocking the commercial power supply supplied from the outside a transformer for reducing the input commercial power a diode for converting the voltage output from the transformer into the direct current a main switch for switching the DC voltage output from the diode and controlling the opening and closing operation of the motors for the opening and closing instruments and individual switches for switching the DC voltage output from the diode and controlling the opening and closing operation of the motors for the opening and closing instruments, separately.COPYRIGHT KIPO 2015본 발명은 한 개의 컨트롤러 박스를 사용하여 각각의 비닐하우스에 설치된 개폐기를 개별적으로 또는 일괄적으로 개폐시킬 수 있도록 함으로써 작업자가 일일이 비닐하우스를 개별적으로 개폐시킬 필요가 없을 뿐만 아니라 간편하고 신속하게 비닐하우스를 개폐시킬 수 있도록 함은 물론 불필요한 전력낭비를 미연에 방지할 수 있도록 하는 비닐하우스 개폐기의 제어장치를 제시한다.
