Description
본 발명은 데이터 전송 장치에 관한 것으로서, 특히 고속 데이터 전송 기능을 갖는 공동주택제어기의 변복조 장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data transmission device, and more particularly, to a modulation and demodulation device for a multi-unit house controller having a high speed data transmission function.
일반적으로, 집단주택(아파트, 맨션등)에서는 경비실에서 각 세대로의 호출 및 음성방송을 통한 공지 사항 전달 등의 기능을 수행하기 위해서는 공동주택제어기가 필요하다.In general, in a multi-family house (apartment, mansion, etc.), a multi-unit house controller is required to perform a function such as a call to each household from the security office and a notice delivery through voice broadcasting.
공동주택제어기의 주요 기능 중 하나는 아파트 동의 현관입구에서 방문하고자 하는 호수를 지정하여 지정된 호수에 있는 사람과 촬상된 영상을 보면서 누구인지를 확인하며 통화를 할 수 있게 한다.One of the main functions of the apartment controller is to designate the lake to be visited at the entrance of the apartment house, allowing the user to check the call and see who is in the designated lake.
이 때, 공동현관기에서 방문자를 촬상한 영상신호와 오디오신호를 변조하여 전송하면, 동제어기는 공동현관기에서 전송된 신호를 제어하여 해당 호수의 세대기에 전송한다. 또한 세대기에서 변조되어 전송되는 영상신호와 오디오 신호를 변조하여 전송하면, 동제어기는 세대기에서 전송된 신호를 제어하여 해당 공동현관기에 전송한다.At this time, if the video signal and audio signal photographed by the visitor is modulated and transmitted from the hall, the controller controls the signal transmitted from the hall and transmits the signal to the generation unit of the lake. In addition, when the video signal and the audio signal modulated and transmitted from the generation unit is modulated and transmitted, the controller controls the signal transmitted from the generation unit and transmits the signal to the corresponding common hall.
여기서, 통상 공동현관기 및 세대기에서 송수신되는 데이터는 ASK(Amplitude Shift Access)방식에 의한 CSMA(Carrier Sensing Multiple Access) 방식으로 송수신된다.Here, the data transmitted and received in the common vestibule and the generation unit is transmitted and received by the CSMA (Carrier Sensing Multiple Access) method by the ASK (Amplitude Shift Access) method.
종래의 제어기와 공동현관기 그리고 세대기간의 송수신 캐리어 주파수로는 125KHz와 260KHz의 사인 웨이브가 이용되며, 송신시에 데이터 1의 전송은 260KHz의 사인 웨이브가 출력되고, 수신시에는 125KHz의 주파수가 선로상에서 검출되면 수신데이터 1로 감지되며 데이터 0의 값은 캐리어 주파수를 전송하지 않는다. 종래에는 비교적 낮은 캐리어 주파수를 사용함으로써 고속 데이터 전송을 할 수 없었다.Conventional controllers, cavities, and transmit / receive carrier frequencies for generation periods use sine waves of 125 KHz and 260 KHz, sine waves of 260 KHz are output during transmission, and 125 KHz frequency is received when receiving. If detected on the received data is detected as data 1 and the value of data 0 does not transmit a carrier frequency. Conventionally, high data rate transmission is not possible by using a relatively low carrier frequency.
본 발명은 상기 문제점을 해결하고자 창출한 것으로서, 캐리어 주파수를 고주파 영역의 주파수로 변경하여 고속 데이터 전송이 가능한 고속 데이터 전송 기능을 갖는 공동주택제어기의 변복조 장치를 제공하는 데 목적이 있다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a demodulation device of a multi-unit house controller having a high speed data transmission function capable of high speed data transmission by changing a carrier frequency to a frequency of a high frequency region.

상기 목적을 달성하기 위한 본 발명에 따른 고속 데이터 전송 기능을 갖는 공동주택제어기의 변복조 장치에 있어서, 고주파의 캐리어 주파수를 발진하는 발진부; 송신데이터에 따라 상기 발진부에서 발진한 고주파의 송신캐리어 주파수를 스위칭하는 아날로그스위치부; 상기 아날로그스위치부에서 스위칭된 송신캐리어 주파수를 증폭하는 제1증폭부; 상기 제1증폭부에서 증폭된 송신캐리어 주파수를 필터링하여 선로상에 전송하거나 수신된 캐리어 주파수를 필터링하는 필터부; 상기 필터부를 통과한 수신캐리어 주파수의 레벨을 제한하는 리미터부; 및 상기 주파수 레벨이 제한된 수신캐리어 주파수를 검파하는 검파부를 포함함이 바람직하다.In the demodulation device of the multi-unit house controller having a high-speed data transmission function according to the present invention for achieving the above object, An oscillation unit for oscillating a high frequency carrier frequency; An analog switch unit for switching a high frequency transmission carrier frequency oscillated by the oscillation unit according to the transmission data; A first amplifier amplifying a transmission carrier frequency switched by the analog switch unit; A filter unit for filtering a transmission carrier frequency amplified by the first amplifier and filtering a carrier frequency transmitted or received on a line; A limiter section for limiting a level of a received carrier frequency passing through the filter section; And a detector for detecting a reception carrier frequency of which the frequency level is limited.
이하 첨부 도면을 참조하여 본 발명을 상세히 설명하기로 한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 공동주택제어기의 변복조 장치의 블록도이다.1 is a block diagram of a modulation and demodulation device of a multi-unit house controller according to the present invention.
도 1에 도시된 장치는 발진부(10), 제1버퍼부(11), 아날로그스위치(12), 제1증폭부(13), 필터부(14), 제2버퍼부(15), 리미터부(16), 검파부(17), 제2증폭부(18)를 포함한다.The apparatus shown in FIG. 1 includes an oscillator 10, a first buffer 11, an analog switch 12, a first amplifier 13, a filter 14, a second buffer 15, and a limiter. (16), a detector 17, and a second amplifier 18.
도 1의 구성에 따른 동작을 살펴보면, 발진부(10)는 고주파인 송신용 캐리어 주파수를 발진하면 제1버퍼부(11)는 발진된 캐리어 주파수를 정형하여 아날로그스위치(12)에 출력한다.Referring to the operation according to the configuration of Figure 1, when the oscillator 10 oscillates the transmission carrier frequency of a high frequency, the first buffer unit 11 forms the oscillated carrier frequency and outputs to the analog switch 12.
이 때, 아날로그스위치(12)는 TxD단자로부터 유입된 송신데이터의 1과 0에 따라 발진된 주파수를 통과 또는 차단시키며 제1증폭부(13)는 통과된 주파수를 증폭 소정의 레벨로 증폭한다. 따라서 고주파로된 캐리어 주파수를 사용함으로써 시간당 보다 많은 정보를 전송할 수 있게 된다.At this time, the analog switch 12 passes or blocks the oscillated frequency according to 1 and 0 of the transmission data introduced from the TxD terminal, and the first amplifier 13 amplifies the passed frequency to a predetermined level. Therefore, by using a carrier frequency of high frequency it is possible to transmit more information per hour.
필터부(14)는 증폭된 신호를 해당 대역의 주파수만 통과시켜 라인에 출력시키고 또한 수신된 라인을 통하여 수신된 신호를 유입하여 제2버퍼부(15)에 출력한다. 제2버퍼부(15)는 수신된 신호의 주파수가 역류되지 않도록 한다. 리미터(16)는 수신된 캐리어 주파수의 레벨을 제한하여 노이즈 성분을 제거하고 소정의 레벨로 조정한다. 리미터(16)에서 레벨 조정된 신호는 검파부(17)에서 검파되고 제2증폭부(18)에서 증폭되어 수신단 RxD에 출력된다.The filter unit 14 outputs the amplified signal to the line by passing only the frequency of the corresponding band, and also receives the signal received through the received line and outputs the signal to the second buffer unit 15. The second buffer unit 15 prevents the frequency of the received signal from flowing back. Limiter 16 limits the level of the received carrier frequency to remove noise components and adjust to a predetermined level. The signal whose level is adjusted by the limiter 16 is detected by the detector 17, amplified by the second amplifier 18, and output to the receiver RxD.
상술한 바와 같이 본 발명에 따른 고속 데이터 전송 기능을 갖는 공동주택제어기의 변복조 장치는 데이터의 비트를 구분짓는 캐리어 주파수를 고주파로 변경함으로써 고속으로 데이터 전송을 할 수 있다.As described above, the modulation and demodulation device of the multi-unit house controller having the high-speed data transmission function according to the present invention can transmit data at high speed by changing the carrier frequency for distinguishing bits of data to high frequency.
