Abstract: An automatic remote-controlled curtain including an actuating device and a control device that controls the actuating device, and which is characterized in that: two ends of an already existent pull cord of a curtain are respectively joined to a gear pull cord of the actuating device with clasps, and the gear pull cord is fitted on a transmission gear of one end of an electric motor. The control device is connected to another end of the electric motor, and control members, including an automatic positioning control member, a temperature control member and a brightness control member are configured within the control device. An external remote control controls a receiver that is further configured on the control device. The aforesaid configuration provides motor-driven remote control, temperature control and light control to an already existent curtain having a sliding mechanism, thereby achieving accurate positioning of curtains and reducing reinstallation costs.
