The invention provides a control method and a control system of an intelligent curtain. The control method comprises the following steps: receiving a first operation instruction input by a user, and performing corresponding preprocessing according to the first operation instruction; when opening conditions are met, generating a control instruction according to the first operation instruction after preprocessing; and transmitting the control instruction to the intelligent curtain, thereby controlling the intelligent curtain to be opened till a first preset opening degree. According to the method, the opening degree is set in advance, when the opening conditions are met, the intelligent curtain can be automatically opened to an expected opening degree, complex button combination operations are avoided, and a user does not need to wait. Compared with a conventional technical scheme, the control method needs a relatively small amount of buttons, a relatively small amount of button combinations, a relatively small number of operation steps, relatively simple operation logics and has relatively convenient and rapid operation experience, so that the problems that the conventional technical scheme is complex in operation and long in waiting time can be solved.
