본 고안은 카스테레오의 교통방송수신 감지회로에 관한 것으로서, 특히 1개의 램프를 사용하여 교통방송국과 교통방송수신 상태를 용이하게 감지하기 위한 교통방송수신 표시회로에 관한 것이다.The present invention relates to a traffic broadcast reception detection circuit of a car stereo, and more particularly, to a traffic broadcast reception display circuit for easily detecting a traffic broadcast station and a traffic broadcast reception state using one lamp.

종래의 교통방송수신시의 램프표시회로에서는 방송국 식별(SK), 방송상태식별(DK)시에 각각의 동작상태를 표시하는 램프를 별도로 2개를 사용하기 때문에, 식별이 용이치 못할뿐 아니라 2개의 램프를 별도로 설치해야만 하므로 이에따라 제품코스트가 상승되는 문제점이 있었다.In the conventional lamp display circuit at the time of receiving a traffic broadcast, since it uses two separate lamps for indicating the operation status at the time of broadcasting station identification (SK) and broadcasting status identification (DK), identification is not easy. Since the two lamps must be installed separately, there was a problem that the product cost is raised accordingly.

따라서, 본 고안은 이와같은 종래의 문제점을 해소하기 위하여 방송국 식별기능 회로와 방송상태 식별기능 회로의 전압차를 이용한 간단한 회로로써 방송국 식별시에는 램프밝기를 약하게 하고, 방송상태 식별시에는 램프밝기를 강하게 조절할 수 있도록 하여 1개의 램프로서 식별을 용이하게 할 수 있도록 한 교통방송 수신표시 회로를 제공하는데 그 목적이 있다.Accordingly, the present invention is a simple circuit using a voltage difference between a broadcasting station identification function circuit and a broadcasting status identification function circuit to solve such a conventional problem, and the lamp brightness is weak when identifying a broadcasting station, and the lamp brightness when a broadcasting condition is identified. It is an object of the present invention to provide a traffic broadcasting reception display circuit that can be strongly controlled to facilitate identification as a single lamp.

이하, 본 고안을 첨부된 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제 1 도는, 본 고안의 회로도로서 방송국 식별회로(IC1)(예를들면 일본국 SANYO사 LA 2205)의 램프제어단자(7)와 방송상태 식별회로(IC2)(예를들면 일본국 SANYO사 LA 2211)의 제어단자(11)사이에 스위치 트랜지스터(Q1), (Q2), 저항(R1∼R4) 및 램프(L1)를 연결하여 구성된 것이다.1 is a circuit diagram of the present invention, and the lamp control terminal 7 and the broadcast state identification circuit IC 2 (for example, SANYO, Japan) of the broadcasting station identification circuit IC 1 (for example, LA 2205, SANYO, Japan). The switch transistors Q 1 , Q 2 , resistors R 1 to R 4 , and a lamp L 1 are connected between the control terminals 11 of the LA 2211.

미설명 부호 B+는 직률전원단자이고, IN는 음성신호 입력단자이다.Unexplained sign B + is the power supply terminal and IN is the audio signal input terminal.

이와같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.

제 1 도에서 교통방송신호를 검파하지 않을 경우에는 방송국 식별회로(IC1)의 램프제어단자(7)는 하이상태가 되고, 방송상태 식별회로(IC2)의 제어단자(11)신호도 하이상태가 된다.When the traffic broadcasting signal is not detected in FIG. 1 , the lamp control terminal 7 of the broadcasting station identification circuit IC 1 becomes high, and the control terminal 11 signal of the broadcasting state identification circuit IC 2 also becomes high. It becomes a state.

이와같은 상태에서는 스위칭 트랜지스터(Q1)가 온됨에 따라 트랜지스터(Q2)가 오프되므로 그의 콜렉터에 집속된 램프(L1)가 소등상태가 된다.In this state, as the switching transistor Q 1 is turned on, the transistor Q 2 is turned off, so that the lamp L 1 focused on the collector thereof is turned off.

한편, 방송상태국을 식별할 경우에는 방송국 식별회로(IC1)의 램프제어(7)신호가 하이상태에서 로우상태로 되고, 그에 따라 저항(R4)에 의한 값에 의해 방송국 식별용으로서 램프(L1)가 점등된다.On the other hand, when identifying the broadcasting station, the lamp control 7 signal of the broadcasting station identification circuit IC 1 goes from the high state to the low state, and accordingly the lamp for identification of the broadcasting station is determined by the value of the resistor R 4 . (L 1 ) lights up.

한편, 방송상태 식별을 할 경우에는 방송상태 식별회로(IC2)의 제어단자(11)신호가 하이상태에서 로우상태로 되는바, 이때 스위칭 트랜지스터(Q1)가 온상태에서 오프상태로 됨과 동시에 트랜지스터(Q2)가 오프상태에서 온상태로 되므로 이경우에는 램프(L1)의 밝기가 완전히 밝아지게 된다. 다시말하면, 방송국 식별시에는 저항(R4)만에 의해 램프(L1)는 완전히 밝아진다. 여기에서 램프(L1)의 밝기는 저항(R4)값과 트랜지스터(Q2)의 턴온에 의해 결정될 수가 있다.On the other hand, in the case of the broadcast state identification, the control terminal 11 signal of the broadcast state identification circuit IC 2 goes from the high state to the low state. At this time, the switching transistor Q 1 is turned off from the on state and at the same time. Since the transistor Q 2 is turned from the off state to the on state, in this case, the brightness of the lamp L 1 becomes completely bright. In other words, the lamp L 1 is completely brightened only by the resistor R 4 when identifying the station. The brightness of the lamp L 1 may be determined by the value of the resistor R 4 and the turn-on of the transistor Q 2 .

이와같이 동작되는 본 고안은 단일의 램프를 사용하여 방송국 식별 및 방송상태 식별기능을 동시에 수행할수 있도록 하여 사용상의 편리함은 물론 제품코스트를 절감할 수 있는 실용적인 고안인 것이다.The present invention operated as described above is a practical design that can reduce the product cost as well as the convenience of use by enabling simultaneous broadcasting station identification and broadcast status identification using a single lamp.
