Remote control device of window curthin

The utility model relates to a controlling device in a remote control type for a window curtain, which comprises a voltage stabilizing power supply, a remote controller IC1, an encoder IC 2 and an inverter IC 3. Power off devices J1, J2, a speed reducing motor D and the encoder IC2 can selectively receive a plurality of sets of frequency signals dispatched by the remote controller IC1 and convert the frequency signals into DC voltage signals to be correspondingly accessed into the inverter IC 3. Each set of signal voltage after inversion is respectively accessed with the power off devices J1, J2. In addition, normal opening contacts of the power off devices J1, J2 control the forward rotation and the reverse rotation of the speed reducing motor D. The utility model has the characteristics of simple structure, convenient use, etc. The utility model can provide convenience for old people, weak people, sick people and disabled people.
