EMBODIMENTS

[0022] The present invention will be further described below through specific embodiments, but the present invention is not limited to the following specific embodiments.

[0023] In a first embodiment, provided is a system for controlling an electric curtain, comprising a remote controller end, a curtain end and a separate NFC electronic tag with a curtain motor ID.

[0024] The remote controller end mainly comprises a housing, a first processor (MCU), a radio frequency transmitting module, a first NFC communication module, a button module and a displaying module. The button module, the radio frequency transmitting module, the first NFC communication module and the displaying module are all in electrical connection with the first processor. The first processor, the first NFC communication module and the radio frequency transmitting module are disposed inside the housing, and the button module and the displaying module are exposed outside the housing. The button module is in charge of user input, the displaying module is in charge of outputting some information to be viewed by a user, the radio frequency transmitting module is in charge of sending information to the curtain end, and the first NFC communication module which is in charge of matching of the remote controller end and the curtain end is active, which is available in many types on market and thus will not be detailed herein.

[0025] The curtain end mainly comprises a second processor (MCU), a radio frequency receiving module, a curtain motor and a motor controller. The radio frequency receiving module and the motor controller are in electrical connection with the second processor, and the curtain motor is in electrical connection with the motor controller. The curtain motor is mainly used to drive the curtain to move so as to realize functions of opening and closing the curtain, the motor controller is mainly used to control the motor, and the radio frequency receiving module is mainly configured to receive information from the radio frequency transmitting module.

[0026] The NFC electronic tag is mainly used to store the curtain motor ID. Further, only one NFC electronic tag may be disposed, so that a user may directly perform matching operation after opening. The NFC electronic tag may also be provided only with the sticking layer, and thus the NFC electronic tag may be stuck at an ordinary position facilitating operation, and the user may perform matching operation by moving the remote controller to approach the stuck electronic tag. The shielding layer may be further disposed behind the sticking layer of the NFC electronic tag, and thus the NFC electronic tag may be stuck on a metal material, for example, on a metal tube, without being interfered by the metal. The NFC electronic tag may also have a hanging buckle, and can be hung at any desired position.

[0027] The whole system works based on the following principle: the remote controller end approaches the NFC electronic tag to enable the first NFC communication module to approach the NFC electronic tag, so that the NFC electronic tag will send its stored curtain motor ID to the first NFC communication module; then, the first NFC communication module sends the received curtain motor ID to the first processor; next, the first processor sends its stored radio frequency ID and the received curtain motor ID to the curtain end through the radio frequency transmitting module, and the radio frequency receiving module of the curtain end receives the curtain motor ID and the radio frequency ID and compares whether a curtain motor ID stored in the curtain end is identical to the received curtain motor ID; if the two motor IDs are same, the radio frequency ID is recorded and two motor IDs are matched, and then, the remote controller end may directly control the motor of the curtain end to operate; if the curtain motor ID stored in the curtain end is not identical to the received curtain motor ID, it indicates that matching is unsuccessful, and the remote controller end cannot control the curtain motor of the curtain end to operate.

[0028] In a second embodiment, provided is a system for controlling an electric curtain, comprising a remote controller end and a curtain end.

[0029] The remote controller end comprises a housing, a first processor (MCU), a radio frequency transmitting module, a first NFC communication module, a button module and a displaying module. The button module, the radio frequency transmitting module, the NFC communication module and the displaying module are all in electrical connection with the first processor. The first processor, the first NFC communication module and the radio frequency transmitting module are disposed inside the housing, and the button module and the displaying module are exposed outside the housing. The button module is in charge of user input, the displaying module is in charge of outputting some information to be viewed by a user, the radio frequency transmitting module is in charge of sending information to the curtain end, and the first NFC communication module which is in charge of matching of the remote controller end and the curtain end is active, which is available in many types on market and will not be detailed herein.

[0030] The curtain end mainly comprises a second processor (MCU), a radio frequency receiving module, a second NFC communication module, a curtain motor and a motor controller. The radio frequency receiving module, the second NFC communication module and the motor controller are in electrical connection with the second processor, and the curtain motor is in electrical connection with the motor controller. The curtain motor is mainly used to drive the curtain to move so as to realize functions of opening and closing the curtain, the motor controller is mainly used to control the motor, and the radio frequency receiving module is mainly configured to receive information from the radio frequency transmitting module. The second NFC communication module which is in charge of matching of the curtain end and the remote controller end is active, which is available in many types on market and thus will not described in detail herein.

[0031] The system works based on the following principle: the remote controller end is moved to approach the curtain end to enable the first NFC communication module in the remote controller end to approach the second NFC communication module in the curtain end; then, the first NFC communication module may obtain a curtain motor ID and then send the curtain ID and the radio frequency ID to the curtain end to facilitate matching the remote controller end with the curtain end.

[0032] Finally, it is to be pointed out that the above embodiments are merely used to describe the technical solutions of the present invention rather than limit the present invention. Although the detailed descriptions are made to the present invention by referring to the preceding embodiments, those skilled in the art should understand that the technical solutions recorded in the above embodiments may still be modified or part of technical features thereof may be equivalently substituted.
