Abstract

본 발명은 무선 통신 장치의 채널 자동 전환 장치에 관한 것이다.The present invention relates to a channel automatic switching device of a wireless communication device.

더욱 구체적으로는 무선 장치간의 통신중에 채널 전환이 가능한 것으로, 무선 통신기기에서 통화중 유입된 잡음(NOISE) 및 방해 전파, 또는 다른 주변 무선 장치와 혼선되는 경우에 미리 정해진 약정에 따라서 자동적으로 채널을 전환하여 원활하게 상호 무선 장치 사이에서 통신이 수행되도록 동작하는 자동 채널 전환 장치에 관한 것이다.More specifically, it is possible to switch channels during communication between wireless devices, and when the wireless communication device is noisy and jammed during a call, or when it is confused with other nearby wireless devices, the channel is automatically changed according to a predetermined agreement. The present invention relates to an automatic channel switching device that operates by switching to facilitate communication between mutual wireless devices.

본 발명의 자동 채널 전환 장치는, 통화 대상용 무선 장치(20)로부터 전송되는 무선 주파수를 수신하기 위한 무선 수신부(5), 수신된 무선 주파수에 포함된 음성신호 및 데이타 정보를 복조하기 위한 기저 신호 복조부(1), 상기 무선 수신부(5)에 입력된 신호의 크기를 판정하여 환선 및 방해 전파의 유무를 검색하기 위한 신호 레벨 검출부(2), 무선 장치 사이의 송신 및 수신 채널을 선택하고 혼선 및 방해 전파의 유무를 판단하여 채널의 전환을 제어하기 위한 제어부(3), 송신용 주파수를 발생시키고 전송하고자 하는 음성 및 데이타 정보를 변조하는 발진 및 변조부(4), 및 송신하고자 하는 무선 주파수를 증폭하여 송신하기 위한 것으로 상기 제어부(3)에 의하여 제어 가능한 무선 송신부(6)로 구성되어 있는 것으로서 미리 설정된 약정 시간 동안에 제어부(3)에서 무선 송신부(6)을 오프(off)시킨후 통화 대상 수신 레벨을 측정하여 방해 전파 및 혼선여부를 판별하여 혼선 및 방해 전파가 없는 채널로 전환하는 것을 특징으로 한다.In the automatic channel switching apparatus of the present invention, a radio receiver 5 for receiving a radio frequency transmitted from the radio communication device 20 for a call, a base signal for demodulating voice signals and data information included in the received radio frequency A demodulator 1, a signal level detector 2 for determining the magnitude of a signal input to the radio receiver 5 to detect the presence or absence of ringing and jamming radio waves, and selecting a transmission and reception channel between the wireless devices and crosstalk And a control unit 3 for controlling channel switching by determining the presence or absence of jammers, an oscillation and modulation unit 4 for generating a transmission frequency and modulating voice and data information to be transmitted, and a radio frequency to be transmitted. It consists of a wireless transmitter (6) which can be controlled by the controller (3) to amplify and transmit the controller (3) during a preset contract time. Standing by the radio transmitter 6 is off (off) to that after measuring the incoming call destination and crosstalk levels determine whether jammer is characterized in that there is no switch to the cross-talk and interference channel.
