본 고안은 시큐리티(security)시스템에 있어서 각 채널의 영상신호를 순차 절환시켜가면서 카메라가 설치된 장소의 영상만이 모니터 화면을 통해 나타날 수 있도록 한 영상신호 순차절환을 이용한 시큐리티 시스템에 관한 것이다.The present invention relates to a security system using video signal sequential switching so that only the image of the place where the camera is installed is displayed on the monitor screen while the video signal of each channel is sequentially switched in the security system.

종래에는 멀티플렉서를 통해 인입되는 채널 각각의 영상신호를 마이컴의 제어에 의해 일정한 주기로 하여 순차적으로 절환시켜가면서 모니터를 통해 카메라가 설치된 장소의 상황을 감시할 수 있도록 한 것이어서, 만약 멀티플렉서의 어떤 채널단자에 카메라가 설치되지 않아 영상신호가 출력되지 않는 채널에서도 무영상상태의 신호가 디스플레이되어 일정시간동안 노이즈로서 나타나게 된다.In the related art, the video signal of each channel input through the multiplexer is sequentially switched at regular intervals under the control of the microcomputer to monitor the situation where the camera is installed through the monitor. Even in a channel where no video signal is output because no camera is installed, a non-video signal is displayed and appears as noise for a predetermined time.

따라서 모니터에는 불필요한 노이즈 화면이 디스플레이되어 감시자의 시각을 피로하게 할 뿐만 아니라 신속한 상황파악을 필요로 하는 시큐리티 시스템에서 불필요한 시간을 소비하게 되는 문제점이 있는 것이다.Therefore, there is a problem that unnecessary noise screen is displayed on the monitor, which not only makes the viewer's eyes tired, but also consumes unnecessary time in the security system requiring rapid situation detection.

본 고안은 이러한 문제점을 해결하기 위하여 안출된 것으로서 1채널에서 n채널까지 각각의 영상신호를 일정한 주기로 절환시켜주면서 모니터를 통하여 감시하는 도중에 카메라가 설치되지 않는 채널 즉 영상신호가 인입되지 않는 채널이 있으면 마이컴에서 이를 인지하여 다음 채널로 스킵(skip)할 수 있도록 해줌으로써 신속하게 카메라가 설치된 장소만의 정보를 제공할 수 있고, 아울러 OSD(On Screen Display)회로를 추가 설치해 줌으로써 감시장소의 위치 및 시간을 모니터를 통해 문자로 식별되도록 해줌으로써, 효율적으로 시간 및 장소를 파악하여 신속 조치할 수 있는 것이다.The present invention was devised to solve such a problem. If there is a channel where a camera is not installed during the monitoring through a monitor while switching each video signal from 1 channel to n channel at regular intervals, there is a channel that does not receive an image signal. By allowing the microcomputer to recognize this and skip to the next channel, it can quickly provide information on the location where the camera is installed, and by installing an additional OSD (On Screen Display) circuit, the location and time of the monitoring location. By identifying them as text on a monitor, you can efficiently identify time and place and take quick action.

이러한 본 고안을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.When the present invention is described in detail by the accompanying drawings as follows.

In the well-known one connected to each other, the synchronization detector 30 and the OSD (On Screen Display) 50 are connected between the output Yo of the multiplexer 10 and the monitor 60, and each channel (CH 1). The buffer B 9 -B 16 of -CH 8 ) is connected to the input terminals I 1 -I 8 of the multiplexer 20, and its output terminal Yo is connected to the synchronization detector 40 and the microcomputer 70. Sequentially connected, the control terminals A ", B", and C "of the microcomputer 70 are connected to the connection terminals A ', B' and C 'of the multiplexer 20, and the microcomputer 70 The output terminal (D) of) is connected to the input terminal (E) of the OSD (50), and reference numeral E denotes an input terminal of the OSD (50) and D denotes an output terminal of the microcomputer (70). The.

이와 같이 구성된 본 고안의 작용효과를 살펴보면 다음과 같다.Looking at the effect of the present invention configured as described above are as follows.

감시 장소에 설치된 각각의 카메라를 통해 영상신호는 각 채널(CH1-CH8)로 인입되어 버퍼(B1-B8) 통해 멀티플렉서(10)의 각 입력단자(I1-I8)로 입력되고, 이와 동시에 버퍼(B8-B16)을 거쳐 멀티플렉서(20)의 각 입력단자(I1-I8)로 동시 입력된다.Through each camera installed in the monitoring station for a video signal is input to each channel is drawn to the (CH 1 -CH 8) buffer (B 1 -B 8), each input terminal (I 1 -I 8) of the multiplexer 10 through At the same time, the signals are simultaneously input to the input terminals I 1 -I 8 of the multiplexer 20 through the buffers B 8 -B 16 .

먼저, 멀티플렉서(10)는 각 입력단자(I1-I8)를 통해 입력된 영상신호를 마이컴(70)의 제어단자(A)(B)(C)에 의해 일정한 주기로 공급되는 출력 데이타에 의하여 각 채널을 순차 출력시켜 모니터(60)로 보내는 것이다.First, the multiplexer 10 may output an image signal input through each input terminal I 1 -I 8 by output data supplied at regular intervals by the control terminals A, B, and C of the microcomputer 70. Each channel is sequentially output to the monitor 60.

한편, 멀티플렉서(10)에서 출력된 각 채널의 영상신호들은 동기검출부(30)에 순차로 인가되어 각기 순차로 동기신호가 검출되고 이는 OSD(50)로 입력되어 상호 동기를 맞추게 되며 마이컴(7)의 출력단자(D)에서 출력되는 타임데이타, 채널 데이타 그리고 클럭 데이타의 각 데이타 신호는 OSD(50)의 입력단자(E)로 입력되어 각 채널에 대응되는 감시장소의 위치 및 시간을 나타내기 위한 정보를 실어 모니터(60)로 직접 입력되는 영상신호와 함께 모니터링(Monitoring)하게 된다.On the other hand, the video signals of each channel output from the multiplexer 10 are sequentially applied to the synchronization detector 30 so that the synchronization signals are sequentially detected, which are input to the OSD 50 to synchronize with each other, and the microcomputer 7 Each data signal of time data, channel data and clock data output from the output terminal (D) of is input to the input terminal (E) of the OSD 50 to indicate the location and time of the monitoring location corresponding to each channel. The information is loaded and monitored together with the video signal input directly to the monitor 60.

이와 동시에, 각 채널(CH1-CH8)을 통해 들어온 영상신호의 일단은 버퍼(B8-B16)를 통해 멀티플렉서(20)의 입력단자(I1-I8)에 인입되고, 130msec정도의 매우 짧은 시간동안에 걸쳐 각 채널(CH1-CH8)의 영상신호 유,무를 확인하여 동기검출부(40)를 통해 검출시킨다.At the same time, one end of the video signal input through each channel (CH 1 -CH 8 ) is introduced into the input terminal (I 1 -I 8 ) of the multiplexer 20 through the buffer (B 8 -B 16 ), about 130msec For a very short time, the presence or absence of a video signal of each channel (CH 1 -CH 8 ) is checked and detected by the synchronization detector 40.

이와 같이 하여 검출된 신호는 마이컴(7)으로 출력시켜 각 채널의 영상동기 신호 유무를 판단하게 되고 동기신호가 있으면 상기 마이컴(7)은 제어단자(A)(B)(C)를 통해 각 채널(CH1-CH8)을 순차 절환하도록 하는 데이타 신호를 멀티플렉서(10)의 접속단자(A')(B')(C')로 출력시켜 각 채널이 설치된 감시장소의 위치 및 시간을 디스플레이하는 OSD(50)의 출력과 함께 모니터(60)를 통해 출력시키게 되고, 동기신호가 없으면 상기 마이컴(70)의 제어단자(A)(B)(C)를 통해 동기신호가 없는 채널을 스킵(skip)하도록 하는 데이타 신호를 멀티플렉서(10)의 접속단자(A')(B')(C')로 출력시켜 이를 OSD(50)의 출력과 함께 모니터(60)로 출력시키게 되는 것이다.The detected signal is output to the microcomputer 7 to determine the presence or absence of a video synchronization signal of each channel. If there is a synchronization signal, the microcomputer 7 transmits each channel through the control terminals A, B and C. Outputs a data signal for sequentially switching (CH 1 -CH 8 ) to the connection terminals A '(B') (C ') of the multiplexer 10 to display the position and time of the monitoring site where each channel is installed. The output is output through the monitor 60 together with the output of the OSD 50. If there is no synchronization signal, the channel without the synchronization signal is skipped through the control terminals A, B, and C of the microcomputer 70. The data signal is output to the connection terminals A ', B', and C 'of the multiplexer 10 and output to the monitor 60 together with the output of the OSD 50.

이를 마이컴의 데이타 처리 상태도를 보인 제 3 도에 도시하였다.This is shown in FIG. 3 showing a microcomputer data processing state diagram.

이와 같이 하여서 된 본 고안은 감시장소에 설치된 카메라의 영상신호를 각 채널을 통해 하나의 모니터(60)로 순차 디스플레이되도록 하였으나, 카메라가 설치되지 않는 채널은 스킵(skip)되도록 하여 불필요한 화면을 제거함으로써 신속한 정보처리가 이루어지도록 하였고, 또한 감시장소의 위치 및 시간을 모니터를 통해 육안 식별하도록 함으로서 감시자가 효율적으로 시간 및 장소를 파악하여 정확한 정보의 전달 및 기록을 할 수 있도록 한 것이다.In this way, the present invention was made to display the video signal of the camera installed in the monitoring place to one monitor 60 sequentially through each channel, but by removing the unnecessary screen by skipping the channel where the camera is not installed. The information processing is promptly performed, and the location and time of the monitoring place are visually identified through the monitor so that the monitor can efficiently identify the time and place to accurately transmit and record the information.
