이와 같이 구성된 본 발명 무선전화기의 다중 접속 장치의 작용,효과를 첨부한 도면 제 1 도 내지 제 3 도에 의거 상세히 설명하면 다음과 같다.When described in detail with reference to Figures 1 to 3 attached to the operation and effect of the multiple access device of the present invention configured as a wireless telephone.

먼저, 본체 시스템(30)의 메인 중앙처리장치(33)는 스캔을 하여 디지털 신서사이저 컨버터부(31)를 통해 수신인지 송신인지를 판단하기 위해 캐리어의 존재유무를 확인한다.First, the main central processing unit 33 of the main body system 30 scans and checks the presence of a carrier to determine whether it is reception or transmission through the digital synthesizer converter unit 31.

이때 캐리어가 존재하지 않으면 모드를 송신모드로 결제하고 송신되는 신호가 46/49Mhz 송수신신호 인지 900M인지를 판단하여 46/49Mhz 송수신신호 이면 900M에 해당하는 송신경로를 클로즈하고, 46/49Mhz 송수신신호 에 해당하는 송신경로를 오픈한다.At this time, if the carrier does not exist, the mode is settled in the transmission mode, and it is determined whether the transmitted signal is a 46 / 49Mhz transmission / reception signal or 900M. If the 46 / 49Mhz transmission / reception signal is closed, the transmission path corresponding to 900M is closed. Open the corresponding transmission path.

이후 46/49Mhz 송수신신호에 대한 송신신호를 발생한 후 신서사이저부(31b)에 인가하게 되며, 이에 따라 신서사이저부(31b)는 송신할 46/49Mhz 송수신신호를 디지털 신서사이저 컨버팅을 하여 신경로 제어부(31d)에 인가한다.Thereafter, after generating a transmission signal for a 46 / 49Mhz transmission / reception signal, the signal is applied to the synthesizer unit 31b. Accordingly, the synthesizer unit 31b converts the 46 / 49Mhz transmission / reception signal to be transmitted to the digital synthesizer to control the control unit 31d. To apply.

송신 경로 제어부(31d)는 송신할 신호를 46/49Mhz 송수신신호 송신경로로 송신을 하게 된다.The transmission path controller 31d transmits the signal to be transmitted by the 46 / 49Mhz transmission / reception signal transmission path.

아울러 상기 송신신호 판단에서 900M 송신일 경우 46/49Mhz 송수신신호에 해당하는 송신경로를 클로즈하고, 900M에 해당하는 송신경로를 오픈한다.In the case of the 900M transmission, the transmission path corresponding to the 46 / 49Mhz transmission / reception signal is closed and the transmission path corresponding to the 900M is opened.

이후 900M에 대한 송신신호를 발생한 후 신서사이저부(31b)에 인가하게 되며, 이에 따라 신서사이저부(31b)는 송신할 900M신호를 디지털 신서사이저 컨버팅을 하여 송신경로 제어부(31d)에 인가한다.Thereafter, after generating a transmission signal for 900M, it is applied to the synthesizer unit 31b. Accordingly, the synthesizer unit 31b converts the 900M signal to be transmitted to the digital path synthesizer and applies it to the transmission path control unit 31d.

이에 따라 송신경로 제어부(31d)는 900M에 대응되는 송신경로로 900M신호를 송신하게 된다.Accordingly, the transmission path controller 31d transmits the 900M signal in the transmission path corresponding to 900M.

한편, 송수신 신호의 스캔중 캐리어가 존재하면 신호수신으로 판단을 하고 모드를 수신모드로 절체한다.On the other hand, if there is a carrier during scanning of the transmission and reception signals, it is determined by signal reception and the mode is switched to the reception mode.

이후 수신경로 제어부(31a)를 통해 수신되는 수신신호를 디지털 신서사이저 컨버터부(31)를 통해 인가받아 46/49Mhz 송수신신호 수신인지 900M신호 수신인지를 판단한다.Thereafter, the reception signal received through the reception path controller 31a is received through the digital synthesizer converter 31 to determine whether the 46 / 49Mhz transmission / reception signal is received or 900M signal reception.

이 판단결과 46/49Mhz 송수신신호 수신이면 수신단(31c)의 900M 수신단(31c")의 경로를 클로즈하고, 46/49Mhz 송수신신호 수신단(31c')의 경로를 오픈한다.As a result of the determination, when the 46 / 49Mhz transmit / receive signal is received, the path of the 900M receiver 31c ″ of the receiver 31c is closed, and the path of the 46 / 49Mhz transmit / receive signal receiver 31c 'is opened.

따라서 수신되는 46/49Mhz 송수신 신호는 신서사이저부(31b)를 통해 디지털 신서사이저 컨버팅이 된 후 상기 오픈된 46/49Mhz 송수신신호 수신단(31c')으로 경로가 형성되어 수신이 된다.Accordingly, the received 46 / 49Mhz transmit / receive signal is converted to a digital synthesizer through the synthesizer unit 31b, and then a path is formed to the open 46 / 49Mhz transmit / receive signal receiver 31c '.

아울러 상기 판단결과 900M호 수신이면 수신단(31c)의 900M 수신단(31c")의경로를 오픈하고, 46/49Mhz 송수신신호 수신단(31c')의 경로를 클로즈한다.In addition, when the 900M call is received, the path of the 900M receiver 31c "of the receiver 31c is opened, and the path of the 46 / 49Mhz transmit / receive signal receiver 31c 'is closed.

따라서 수신되는 900M신호는 신서사이저부(31b)를 통해 디지털 신서사이즈 컨버팅이 된 후 상기 오픈된 900M수신단(31c')으로 경로가 형성되어 수신이 되는 것이다.Therefore, the received 900M signal is converted to the digital synthesizer size through the synthesizer unit 31b, and then a path is formed to the open 900M receiver terminal 31c 'to be received.

이상에서 상세히 설명한 바와 같이 본 발명은 C/T(Cordless Telephone)가 다른 신호를 각 경로별로 분할하여 접속함으로써 통화품질을 향상시킴과 아울러 통달거리를 확보할 수 있는 효과가 있다.As described in detail above, the present invention has an effect of improving call quality and securing communication distance by separating and connecting different signals by C / T (Cordless Telephone) for each path.
