Abstract

본 발명은 RF와 IR의 송수신 장점을 이용하여 양호한 음성 송수신을 이루도록하므로 가정 자동화 시스템이나 음성 인식 제품에 적당하도록 한 RF와 IR을 겸용한 음성송수신 장치 및 수신방법에 관한 것으로 기존에는 음성송수신 매체를 RF로 할 경우 혼신에 약하고 IR로 할 경우 잡음성은 양호하나 공간을 초월할 수 없었는바 본 발명에서는 IR송신부(5)와 RF송신부(16)에 의해 동시에 송신이 이루어지도록 하고 IR와 RF 수신 신호를 비교하여 수신감도가 양호한 쪽을 선택하도록 구성하여 항상 양호한 송수신 상태를 얻을 수 있도록 한 것이다.The present invention relates to a voice transmission / reception apparatus and a reception method using both RF and IR, which are suitable for home automation systems or voice recognition products, by using the advantages of RF and IR transmission and reception. In the case of RF, the interference is weak and in the case of IR, the noise is good but the space cannot be exceeded. In the present invention, the IR transmitter 5 and the RF transmitter 16 simultaneously transmit the IR and RF received signals. In comparison, a good reception sensitivity is selected so that a good transmission and reception state can be obtained at all times.

Claims

IR signal is transmitted to the amplification section 1, 1a through the automatic gain control section 2, 2a, FM modulation section 3, 3a, and band pass filter 4, 4a. The transmitting section 5 and the RF transmitting section 16 are configured to transmit simultaneously, and the receiving diode section 6 and the PCB antenna 18, each of the band pass filters 7 and 7a and the RF amplifier 8, 8a), FM front-end (9) (9a), ceramic filter (10) (10a), FM intermediate frequency section (11) (11a), FM demodulation section (12) (12a), high pass filter (13) ( A voice transceiver comprising both RF and IR, which is configured to compare the received IR signal with the received RF signal through 13a) to select a better reception sensitivity.

A reference signal is set for a predetermined regulated digital signal (L ₉ ), and an IR demodulated signal is stored in L ₁ , and an RF demodulated signal is stored in L ₂ , and then the L ₉ and L ₁ are determined to be the same. and L ₉ and L ₁ are the same, select the sheet dia as L ₁ and L ₉ and different from the L _1, L ₉ and L RF to ₁ is selected for every dia when the L ₉ and L ₁ be the same to determine the same as L ₂ Voice reception method using both IR and IR.
