Description

RADIO FREQUENCY IDENTIFICATION REMOTE CONTROL SYSTEM FOR APPLIANCE
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to a remote control system for appliances, especially to a remote control system based on radio frequency identification (RFID) for control of appliances.
Description of Related Art
The remote controllers available now can be divided into two major groups according to the ways of signal transmission: infrared (IR) remote controller and radio frequency (RF) remote controller. In IR remote control, an IR LED is required to transmit IR signals. The directional nature of IR makes it more limited. Thus IR remote control is used for control of home appliances such as television, air-conditioner, etc. Compared with IR remote control, the RF remote control uses radio waves to transmit control signals and it has multi-directional nature. Thus the RF remote control has more applications ranging from home appliances, to remote control toy cars, to remote control of cars or motorcycles, and anti-theft security i
system.
Either IR remote control or RF remote controller needs batteries to run for sending control signals. Moreover, the remote controller has a certain thickness and a lot of electronic components are required for circuit. Thus the production cost is high.
SUMMARY OF THE INVENTION
Therefore it is a primary object of the present invention to provide a RFID remote control system for appliances in which neither battery nor copper wire used for connecting switches for appliances is required. The cost of the overall architectural wiring for appliances can also be reduced. Moreover, the remote controller with the RFID tag therein can be much thinner, lighter and more transparent.
In order to achieve the above object, a RFID remote control system for appliances according to the present invention includes a remote controller, a control unit and at least one load controller. The control unit consists of a RFID reader and a processor while the remote controller is provided with a RFID tag and a switch component.
The RFID tag can be switched between a usually available disable mode and an enable mode by the switch component. The RFID tag in the disable mode is unable to be read by the RFID reader while the RFID tag in the enable mode can be read by the RFID reader. The RFID reader reads identification information in the RFID tag and then transmits the identification information to the processor. The processor drives the corresponding load controller according to content of the content of the identification information received. Thus the appliance is turned on or turned off.
The RFID tag includes a chip and an antenna while the antenna consists of a radiator and an impedance matching adjusting portion. The chip is electrically connected to a signal feed point of the radiator while the impedance matching adjusting portion is a circular open-loop segment. A feed end of the impedance matching adjusting portion is electrically connected to the signal feed point of the radiator while an open-loop end of the impedance matching adjusting portion is electrically connected to the switch component.
The impedance matching adjusting portion includes a first line segment and a second line segment parallel to each other. A front end of the first line segment and a front end of the second line segment are used as the feed end of the impedance matching adjusting portion and are electrically connected to the chip respectively. A rear end of the first line segment and a rear end of the second line segment are used as the open-loop end of the impedance matching adjusting portion and are electrically connected to the switch component.
The switch component is in contact with the open-loop end of the impedance matching adjusting portion so as to make the electrical connection.
The switch component can be a contact micro switch or a self-lock micro switch.
The open-loop end of the impedance matching adjusting portion is provided with electrodes that are in contact with the switch component to make electrical connection therebetween.
The processor can also be electrically connected to the RFID reader and a plurality of load controllers while the load controllers are electrically connected to different appliances respectively. A plurality of RFID tags is disposed on the remote controller and each RFID tag is electrically connected to a corresponding switch component. Thereby the remote control system can turn on or turn off the plurality of appliances.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
Refer to Fig. 1, a radio frequency identification (RFID) remote control system according to the present invention includes a remote controller 10, a control unit 20 and a load controller 30. The basic function of the RFID remote control system consists of turning on/or turning off at least one appliance E. In the following embodiments shown in figures, the appliance E is a luminaire. The appliance E can also be other appliances such as air conditioner or power socket. The appliance E and a power source (such as alternating current (AC) power source and direct current (DC) power source) are electrically connected or disconnected by the corresponding load controller 30 of the present RFID remote control system.
The control unit 20 consists of a RFID reader 21 and a processor 22 while the remote controller 10 is composed of a RFID tag 40 and a switch component 50. The switch component 50 is used to switch the RFID tag 40 between a usually available disable state and an enable state. The RFID tag 40 in the disable state is unable to be read by the RFID reader 21 while the RFID tag 40 in the enable state is able to be read by the RFID reader 21. The RFID reader 21 usually available in a read mode is used for reading identification information stored in the RFID tag 40 and transmitting the identification information obtained to the processor 22 for identification and processing purposes. Then the processor 22 drives the load controller 30 correspondingly according to the content of the identification information received so as to turn on or turn off the appliance E correspondingly.
In a preferred embodiment, the RFID tag 40 is a passive RFID tag (no battery/power source is needed). The RFID reader 21 in an operating environment transmits a radio signal to interrogate the RFID tag 40 and the RFID tag 40 then responds with the identification information. Thus the remote controller 10 requires no battery. The cost of the overall architectural wiring for the appliance(s) E can also be reduced.
The RFID tag 40 of the remote controller 10 includes a chip 41 and an antenna 42. The antenna 42 consists of a radiator 43 and an impedance matching adjusting portion 44. The chip 41 is electrically connected to a signal feed point P of the radiator 43 while the impedance matching adjusting portion 44 is used for determining antenna input impedance. The RFID tag 40 only works normally and responds to the RFID reader 21 when the input impedance of the impedance matching adjusting portion 44 and the impedance of the chip 41 are matched.
Refer to Fig. 2, in a preferred embodiment of the present invention, the impedance matching adjusting portion 44 is a circular open-loop segment. A feed end of the impedance matching adjusting portion 44 is electrically connected to the signal feed point P of the radiator 43 while an open-loop end 443 of the impedance matching adjusting portion 44 is electrically connected to the switch component 50.
The electrical connection of the open-loop end 443 of the impedance matching adjusting portion 44 is achieved selectively by the switch component 50 to make the impedance matching adjusting portion 44 become a complete loop. Thus the input impedance of the impedance matching adjusting portion 44 is matched to that of the chip 41. In other words, the RFID tag 40 only works in response to a reading operation of the RFID reader 21 after the impedance matching adjusting portion 44 being a complete loop.
Still refer to Fig. 2, in a preferred embodiment, the impedance matching adjusting portion 44 includes a first line segment 441 and a second line segment 442 parallel to each other. A front end of the first line segment 441 and a front end of the second line segment 442 are used as the feed end of the impedance matching adjusting portion 44 and are electrically connected to the chip 41 respectively. A rear end of the first line segment 441 and a rear end of the second line segment 442 are used as the open-loop end 443 of the impedance matching adjusting portion 44 and are electrically connected to the switch component 50.
In a preferred embodiment, the switch component 50 is a touch switch such as a membrane touch switch. The switch component 50 is in contact with the open-loop end 443 of the impedance matching adjusting portion 44 so as to make the electrical connection. The switch component 50 can be a contact micro switch or a self-lock push switch.
In a preferred embodiment, the antenna 42 is created by flexographic printing. The radiator 43 and the impedance matching adjusting portion 44 can be produced by etching or printing. The materials for the radiator 43 and the impedance matching adjusting portion 44 include metal film and conductive ink. Thus the remote controller 10 can be much thinner, lighter, and more transparent, for being attached to the wall of the building while in use.
In a preferred embodiment, the radiator 43 and the impedance matching adjusting portion 44 are made from conductive ink containing graphene. As shown in Fig. 2, electrodes 444 made from conductive silver paste are arranged at the open-loop end 443 of the impedance matching adjusting portion 44. The electrodes 444 are in contact with the switch component 50 to make electrical connection for solving the problem of poor abrasion resistance of graphene and extending the service life. Refer to Fig. 3, in a further preferred embodiment, the open-loop end 443 of the impedance matching adjusting portion 44 is electrically connected to two metal electrodes 446 by printed circuits 445 respectively. The metal electrodes 446 are in contact with the switch component 50 to make electrical connection. Thereby the problem of poor abrasion resistance of graphene can be solved and the service life is extended.
Refer to Fig. 4, in a further preferred embodiment, the processor 22 is electrically connected to the RFID reader 21 and a plurality of load controllers 30, 31, 32, 33 while the load controllers 30, 31, 32, 33 are electrically connected to different appliances El, E2, E3 and E4 respectively. A plurality of RFID tags 40 is disposed on the remote controller 10. Each RFID tag 40 is electrically connected to a corresponding switch component 50 and having different identification information therein. By operating the corresponding the switch component 50 of the respective RFID tag 40, different identification information is transmitted to the RFID reader 21 and then the identification information obtained is further sent to the processor 22 for identification and processing purposes. Next the processor 22 drives the corresponding load controllers 30^33 according to the content of the identification information received so as to turn on or turn off the corresponding appliances El~ E4. Thereby the construction of the remote control system that can turn on or turn off the appliances El ~E4 has been completed.
Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details, and representative devices shown and described herein. Accordingly, various io modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and their equivalent.
