Technical Field The disclosure relates to the technical field of curtains, and in particular relates to a control method, a control system, electronic equipment and a program product of an electric curtain. Background The rolling curtain is a curtain which can realize the functions of shading and adjusting light by driving the whole curtain to roll up and down through the rolling shaft, and can easily adjust indoor light due to convenient operation, small occupied space, no occupation of excessive space inside and outside the window, and suitability for various decoration styles, thus being widely applied to various office places and family designs. In order to achieve the effect of shielding the view of the upper lighting and the lower part of the roller blind type curtain, a floating curtain (an upper open roller blind) is generated. Two fixed pulleys are respectively arranged on two sides of the top of a window, a traction rope is utilized to bypass a movable pulley arranged at two ends of a roller shutter shaft, and a bottom beam with a certain weight is arranged at the bottom of a curtain cloth, so that the curtain cloth on the roller shutter shaft is unfolded from the lower part to the upper part or folded from the upper part to the lower part under the action of the bottom beam while the roller shutter shaft is driven to ascend/descend by driving the rotation of the fixed pulleys. However, in the existing suspension curtain, when the curtain is unfolded or folded, the bottom beam at the bottom of the curtain has a larger position offset along with the movement of the roller shutter shaft, for example, when the roller shutter shaft moves upwards, the bottom beam is also driven to move upwards, so that the position of the bottom beam cannot be kept still to really achieve the suspension effect, and the user experience is poor.
