본 고안은 감시용 카메라가 장착된 브이씨알(Video Cassette Recorder)에 있어서, 이동되는 파사체를 감시용 카메라가 자동으로 추적하면서 촬영할 경우에 이를 검출하여 자동으로 녹화하게한 감시용 카메라가 장착된 브이씨알의 자동녹화회로에 관한 것이다.The present invention, in the video cassette recorder equipped with a surveillance camera, the V-seal equipped with a surveillance camera that detects and records automatically when the moving camera takes a picture while tracking the moving object automatically It relates to automatic recording circuit of.
종래에는 사람이 모니터를 계속 관찰하면서 이상한 움직임이 포착되면 녹화스위치를 조작하여 녹화하거나 또는 계속 녹화상태로 만들어 녹화하게 하였으나, 전기한 사람이 녹화스위치를 조작하여 녹화하는 것은 인위적인 실수 및 지연등에 의하여 이상한 움직임을 정확히 녹화할 수 없고, 후기한 계속 녹화하게 한 것을 불필요한 장면 즉,피사체의 움직임이 없는 경우에도 녹화하게 되어 필요없이 많은 테이프가 소모되는 결함이 있었다.Conventionally, when a person observes the monitor and captures strange movements, the recording switch is operated to record or to keep recording. However, the electrician can record by controlling the recording switch due to artificial mistakes and delays. There was a defect that it was not possible to record the movement accurately, and that the continuous recording of the latter was recorded even when there is no unnecessary scene, that is, even when there is no movement of the subject, so that a lot of tape is consumed without need.
본 고안은 이와 같은 종래의 결함을 감안하여 감시용 카메라가 이상한 움직임을 자동으로 추적하면서 촬영할경우에 구동되는 자동초점렌즈구동용 모니타의 정방향 및 역방향 구동제어전압을 이용하여 이상한 움직임이 있으면 자동으로 녹화하게 안출한 것으로, 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention takes account of such a conventional defect and automatically records abnormal movements by using the forward and reverse driving control voltages of the auto focus lens driving monitor which is driven when the surveillance camera automatically records the abnormal movements. As described above in detail by the accompanying drawings as follows.
첨부된 도면은 본 고안의 브이씨알의 자동 녹화회로도로서, 이에 도시한 바와 같이 정방향 및 역방향 구동제어 전압단자(FO)(RE)가 베이스에 접속된 트랜지스터(TR1)(TR2)의 애미터를 접지저항(R3),(R4) 및 다이오드(D1),(D2)를 각기 통한 후 콘덴서(C1) 및 저항(R5)으로된 미분기(1)의 입력단자에 공통접속하여, 그 미분기(1)의 출력단자를 다이오드(D3) 및 트랜지스터(TR3)의 베이스에 접속하고, 그 트랜지스터(TR3)의 콜렉터는 트랜지스터(TR4,TR5) 및 저항(R6-R10), 콘덴서(C2), 다이오드(D4)로 된 모노멀티(2)의 입력단자에 접속하여, 그 모노멀티(2)의 출력단자를 트랜지스터(TR6)의 베이스에 접속하면, 트랜지스터(TR6)의 콜렉터는 저항(R11) 및 브이씨알의 녹화제어단자에 접속하여 구성한 것으로, 상기에서 감시용 카메라에 이상한 움직임이 포착되어 감시용 카메라의 자동초점렌즈구동용 모타가 구동되면서 자동추적촬영할 경우에 그 모타에 인가되는 정방향 및 역방향 구동전압이 구동제어전압단자(FO)(RE)로 입력되게 하고, 녹화제어 단자에 저전위 신호가 인가되면 감시용 카메라가 촬영한 신호를 녹화하게 하며, 도면의 설명중 미설명부호 Vcc-VEE는 전원단자이다.The accompanying drawings are an automatic recording circuit diagram of the VR of the present invention, and as shown therein, the emitters of the transistors TR1 and TR2 having the forward and reverse driving control voltage terminals FO RE connected to the base are grounded. After the resistors R3, R4 and diodes D1 and D2 are respectively connected, they are commonly connected to the input terminal of the differentiator 1 composed of the capacitor C1 and the resistor R5. The output terminal is connected to the base of the diode D3 and the transistor TR3, and the collector of the transistor TR3 is connected to the transistors TR4 and TR5 and the resistors R6-R10, the capacitor C2, and the diode D4. When connected to the input terminal of the monomulti 2, the output terminal of the mono multi 2 is connected to the base of the transistor TR6, and the collector of the transistor TR6 controls the recording of the resistors R11 and V-CAL. Connected to the terminal, the strange movement is captured by the surveillance camera in the above, the automatic focus of the surveillance camera When the lens driving motor is driven and auto tracking is performed, the forward and reverse driving voltages applied to the motor are input to the driving control voltage terminal (FO) RE, and when the low potential signal is applied to the recording control terminal, The camera records the captured signal, and the description Vcc-V EE in the figure is a power supply terminal.
이와 같이 구성된 본 고안의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effect of the present invention configured in this way in detail as follows.
전원단자(Vcc)(-VEE)에 전원이 인가되고, 이상한 움직임이 없어 감시용 카메라의 자동초점렌즈 구동용 모타가 구동되지 않음에 따라 정방향 및 역방향 구동제어전압단자(FO)(RE)로 저전위 신호가 입력되면, 트랜지스터(TR1)(TR2)가 모두 오프되어 그의 에미터에 저전위 신호가 출력되고, 이에 따라 미분기(1)에서 미분되는 신호도 없어 트랜지스터(TR3)가 오프되므로 모노멀티(2)의 출력단자에는 저전위 신호가 출력된다. 즉 이때 모노멀티(2)의 콘덴서(C2)에는 전원단자(Vcc)의 전압이 충전되어 트랜지스터(TR5)의 베이스에 인가되므로 그의 콜렉터에 저전위 신호가 출력되고, 이 저전위 신호에 의해 트랜지스터(TR4)의 베이스에 저전위 신호가 인가되어 그 트랜지스터(TR4)가 오프된다.Power is supplied to the power terminal (Vcc) (-V EE ) and the motor for driving the auto focus lens of the surveillance camera is not driven because there is no abnormal movement. Therefore, the forward and reverse driving control voltage terminals (FO) (RE) When the low potential signal is input, all of the transistors TR1 and TR2 are turned off, and a low potential signal is output to the emitter thereof. As a result, the transistor TR3 is turned off because there is no signal to be differentiated in the differentiator 1. A low potential signal is output to the output terminal of (2). That is, at this time, the capacitor C2 of the monomulti 2 is charged with the voltage of the power supply terminal Vcc and applied to the base of the transistor TR5, so that a low potential signal is output to the collector thereof. The low potential signal is applied to the base of TR4, and the transistor TR4 is turned off.
이와 같이 모노멀티(2)의 출력단자인 트랜지스터(TR5)의 콜렉터에서 출력된 저전위 신호를 트랜지스터(TR6)의 베이스에 인가되어 그가 오프되므로 녹화제어단자에 고전위 신호가 인가되어 감시용 카메라가 촬영한 신호를 녹화하지 않게 된다.As such, the low potential signal output from the collector of the transistor TR5, which is the output terminal of the monomulti 2, is applied to the base of the transistor TR6 and turned off, so that a high potential signal is applied to the recording control terminal. The recorded signal will not be recorded.
이와 같은 상태에서 이상한 움직임이 있어 이를 감시용 카메라가 촬영하고, 감시용 카메라의 자동초점렌즈구동용 모타가 정방향 또는 역방향으로 구동되어 구동제어전압단자(FO)또는(RE)로 구동제어전압이 입력되면, 트랜지스터(TR1)또는(TR2)가 온되어 그의 에미터에 고전위 신호가 출력되고, 그 고전위신호는 다이오드(D1)또는(D2)를 통하고, 미분기(1)를 통해 미분되어 마이너스펄스신호는 다이오드(D3)에 의해 제거된 후 트랜지스터(TR3)의 베이스에 인가되므로 트랜지스터(TR3)가 온되어 모노멀티(2)의 트리거 펄스입력단자인 트랜지스터(TR4)의 콜렉터에 저전위 신호가 인가되고 이에 따라 그 모노멀티(2)는 저항(R7) 및 콘덴서(C2)의 시정수에 의해 그의 출력단자인 트랜지스터(TR5)의 콜렉터에 일정시간동안 고전위 신호가 출력되고, 이와 같이 출력된 고전위 신호를 트랜지스터(TR6)의 베이스에 인가되므로 그 트랜지스터는 일정시간동안 온되어 녹화제어 단자에 저전위 신호가 인가되면서 일정시간동안 녹화하게 된다.In this state, there is a strange movement and the surveillance camera photographs it, and the motor for driving the auto focus lens of the surveillance camera is driven in the forward or reverse direction so that the driving control voltage is input to the driving control voltage terminal (FO) or (RE). When the transistor TR1 or TR2 is turned on, a high potential signal is outputted to the emitter thereof, and the high potential signal is differentiated through the differentiator 1 through the diode D1 or D2 and minus. Since the pulse signal is removed by the diode D3 and applied to the base of the transistor TR3, the transistor TR3 is turned on so that the low potential signal is applied to the collector of the transistor TR4, which is the trigger pulse input terminal of the monomulti 2. A high potential signal is applied to the collector of the transistor TR5, the output terminal of which is applied by the time constant of the resistor R7 and the capacitor C2, for a predetermined time. High Since the arc is the base of the transistor (TR6) that transistor is applied as the low potential signal to the recording control terminal is turned on for a certain period of time is recorded for a certain period of time.
이상에서 설명한 바와 같이 본 고안은 이상한 움직임이 있으면 자동으로 녹화하게 되므로 일일이 사람이 모니터링할 필요가 없음은 물론 필요없이 녹화를 하지않게 되는 효과가 있다.As described above, the present invention is automatically recorded when there is a strange movement, so there is no need to monitor one by one, and there is an effect of not recording without need.
