본 고안은 전기제품의 원격제어를 위한 리모콘회로에 관한 것으로 특히 가시거리이외의 장소에서도 세트의 원격제어를 가능하게하기위한 저전력 고주파 리모콘회로에 관한 것이다.The present invention relates to a remote control circuit for remote control of electrical appliances, and more particularly to a low-power high-frequency remote control circuit for enabling remote control of the set in places other than the visible distance.
현재 널리 응용되고 있는 리모콘시스템은 제1도에서 보이고 있는 바와 같이, 리모콘 마이콤(10)내의 엔코더(11)에서 발생된 제어데이터신호로써 포토다이오드(LED)(12)를 구동하여 적외선을 발생시키게 하고, 이러한 적외선 제어 신호는 세트에 장작된 포토센서(14)에서 검출하여 디코더(17)를 거쳐 세트마이콤(16)에서 인식하게 설계된다.As shown in FIG. 1, a remote control system that is widely used currently generates infrared rays by driving a photodiode (LED) 12 as a control data signal generated by the encoder 11 in the remote control microcomputer 10. The infrared control signal is designed to be detected by the photosensor 14 mounted on the set and recognized by the set microcomputer 16 via the decoder 17.
그러나 상기와 같은 적외선 리모콘시스템은 가시거리에서만 사용가능할 뿐만아니라 리모콤을 세트방향으로 겨냥하지 않으면 근거리에서도 원격제어되지않는 문제점이 있다.However, the infrared remote control system as described above may not only be used at a visible distance but also may not be remotely controlled at a short distance unless the remote control is aimed in the set direction.
특히, 적외선 리모콘의 경우 송수신시에 발생되는 적외선외에 형광등이나 백열전구등에서 발생되는 또다른 적외선이 실내에 존재하기 때문에 혼신에 따른 원격제어 에러가 일어나기쉽다.In particular, in the case of an infrared remote control, since there is another infrared ray generated in a fluorescent lamp or an incandescent lamp in addition to the infrared ray generated at the time of transmission and reception, a remote control error due to interference is likely to occur.
본 고안은 이와 같은 문제점을 해결하기 위한 안출한 것으로 리모콘의 송수신제어신호를 RF신호로 변환하여 송출 및 수신함으로써 형광등 기구등에 의한 세트 제어 에러를 방지하고 가시거리이외의 장소에서도 세트제어가 가능한 저전력 고주파 리코콘회로를 제공하는데 목적이 있다.The present invention is designed to solve such a problem, and by converting the transmission / reception control signal of the remote control into an RF signal and transmitting and receiving it, it is possible to prevent a set control error caused by a fluorescent lamp, etc. The purpose is to provide a licocon circuit.
이하 첨부된 도면에 기초하여 본 고안을 설명하면다음과 같다.Hereinafter, the present invention will be described based on the accompanying drawings.
제2도는 본고안 고주파(RF)리모콘 회로구성도로써, 리모콘마이콤(10)의 엔코더(11)에서 발생된 리모콘 제어데이터신호는 RF변조기(18)에서 고주파신호로 변환되어 안테나(19)로 송출되게 구성하고, 수신부의 수신안테나(21)로 들어오는 고주파제어신호는 RF검파기(20)에서 검파된 후 세트마이콤(16)내의 디코더(17)에서 리모콘제어신호로 인식되도록 연결구성한다.2 is a schematic diagram of a high frequency (RF) remote control circuit, in which a remote control control data signal generated by the encoder 11 of the remote controller microcomputer 10 is converted into a high frequency signal by the RF modulator 18 and transmitted to the antenna 19. The high frequency control signal coming into the receiving antenna 21 of the receiving unit is detected by the RF detector 20 and then connected to be recognized as a remote control control signal by the decoder 17 in the set microcomputer 16.
제3도는 본 고안 리모콘회로의 RF변조기(18)에 대한 구체적인 회로구성도로 엔코더(11)에서 출력되는 펄스열형태의 데이터신호는 베이스입력저항(R1)을 통하여 인덕터(L1)와 콘덴서(C1)에 의한 공진탱크회로를 거쳐 고주파 트랜지스터(Q1)의 베이스로 인가되게 연결하고, 발진공진용 콘덴서(C3)가 콜렉터-에미터사이에 설치되며 출력저항(R3)을 통하여 Vcc전압이 공급되고 바이어스저항(R2) 및 바이패스 콘덴서(C2)가 에미터측에 연결된 상기 고주파트랜지스터(Q1)의 콜렉터출력을 송신안테나(19)를 통하여 송출되게 연결하여 구성한다.3 is a detailed circuit diagram of the RF modulator 18 of the remote control circuit of the present invention. The data signal in the form of a pulse train output from the encoder 11 is connected to the inductor L 1 and the capacitor C through the base input resistance R 1 . 1 ) is connected to the base of the high frequency transistor (Q 1 ) via the resonant tank circuit, and the oscillating resonance capacitor (C 3 ) is installed between the collector and the emitter, and the Vcc voltage through the output resistor (R 3 ) The collector output of the high frequency transistor Q 1 , which is supplied with the bias resistor R 2 and the bypass capacitor C 2 connected to the emitter side, is fed out through the transmission antenna 19.
이와 같이 구성된 본 고안의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above are as follows.
먼저 리모콘마이콤(10)에서는 외부키 입력에 따른 신호를 엔코더(11)에서 펄스폭 변조된 펄스열형태의 디지털 데이터로 변환출력한다. 이러한 데이터는 RF 변조기(18)의 저항(R1)을 통하여 RF트랜지스터(Q1)의 베이스측으로 입력된다. 이때 트랜지스터(Q1)의 베이스측에는 마이크로스트립라인으로 구현된 인덕터(L1)와 콘덴서(C1)에 의한 공진탱크회로가 마련되어 있어 발진이 일어나게 되는데, 상기 트랜지스터(Q1)에서의 발진은 데이터펄스가 하이일때만 일어나게 되므로 불필요한 전력소모를 최소화시킬수 있게된다.First, the remote controller microcomputer 10 converts and outputs a signal according to an external key input into digital data having a pulse width modulated by the encoder 11. This data is input to the base side of the RF transistor Q 1 through the resistor R 1 of the RF modulator 18. At this time, the transistor (Q 1) resonant tank circuit by an inductor (L 1) and capacitor (C 1) implemented in a base side of the microstrip line of the feature here there is to occur the oscillation, oscillation in the transistor (Q 1) is data This occurs only when the pulse is high, minimizing unnecessary power consumption.
이와 같이 엔코더(11)의 디지털 데이터펄스의 하이레벨 입력시에서만 발진하는 RF트랜지스터(Q1)의 콜렉터출력은 콘덴서(C3)를 통하여 피이드백 증폭되어 송신안테나(19)를 거쳐 RF신호로 송출된다. 이러한리모콘의 RF제어신호는 세트측의 수신안테나(21)에 수신되어 RF검파기(20)에서 검파되어 최초의 디지털 데이터로 변환출력되며, 이에따라 세트마이콤(16)의 디코더(17)는 디지털 데이터입력을 인식하여 원격제어에 따른 세트의 동작제어출력을 내게된다.In this way, the collector output of the RF transistor Q 1 oscillated only at the high level input of the digital data pulse of the encoder 11 is fed back amplified through the capacitor C 3 and transmitted as an RF signal through the transmission antenna 19. do. The RF control signal of the remote control is received by the receiving antenna 21 on the set side, detected by the RF detector 20 and converted into the first digital data, and accordingly, the decoder 17 of the set microcomputer 16 inputs digital data. Recognize this and send out the operation control output of the set according to remote control.
그러므로, 본 고안은 기존의 적외선리모콘에서의 단점, 즉 가시거리내에서만의 원격제어 및 기타 전등에서 발생되는 적외선과의 혼신가능성을 완전히 배제시킬 수 있으며, 원격제어송신거리의 확장이 가능하게 된다.Therefore, the present invention can completely eliminate the disadvantages of the existing IR remote control, that is, the possibility of interference with infrared rays generated from the remote control and other lights only within the visible distance, and the remote control transmission distance can be extended.
특히 본 고안은 원격제어 키 입력에 따른 데이터출력시에만 회로동작전력이 소모되도록 설계됨에 따라 리모콘의 조소비전력화를 달성할수 있다.In particular, the present invention can achieve the power consumption of the remote control, as the circuit operation power is only consumed at the time of data output according to the remote control key input.
