이와 같이 구성된 출력장치의 동작을 설명한다.The operation of the output device configured as described above will be described.
먼저, 실내(ROOM)방송시,First, in the room broadcast,
사령실(1), 중앙제어기(2), 측면제어기(3)의 자동방송장치로 부터 콘넥터(46)의 2번핀에 100V 신호가 인가되면 트래지스터(Q10)의 베이스에 전류가 흐르게 되어 트래지스터(Q10)가 구동된다. 이에 따라, 이 트래지스터(Q10)의 콜렉터에 연결되어 있는 릴레이(51)가 구동되고, 출력트랜스(T2)에 전압이 유기되므로써 접점(a1)(a2) 및 콘넥터(47)를 통해 실내스피커(6)가 연결된다. 한편, 상기 릴레이(51)가 구동됨에 따라 저항(R50)을 통해 소정값의 전류가 흐르게 되고 콘넥터(46)의 5, 6번핀에 접속되어있는 램프(11)가 점등된다. 즉, 콘넥터(46)에 연결된 램프(11)는 트래지스터(Q10)의 콜렉터 전윈가 로우레벨이 되면 전류가 흘러 점등된다.When a 100V signal is applied to pin 2 of the connector 46 from the automatic broadcasting device of the command room (1), the central controller (2), and the side controller (3), current flows to the base of the transistor (Q10). Q10) is driven. Accordingly, the relay 51 connected to the collector of the transistor Q10 is driven, and the voltage is induced in the output transformer T2, so that the indoor speaker (A1) through the contact point a1 and the connector 47 is connected. 6) is connected. Meanwhile, as the relay 51 is driven, a current of a predetermined value flows through the resistor R50, and the lamp 11 connected to pins 5 and 6 of the connector 46 is turned on. That is, the lamp 11 connected to the connector 46 is turned on when current flows when the collector power of the transistor Q10 becomes low level.
한편, 상기 실내 스피커(6)가 연결된 상태에서 상기 릴레이(51)의 구동에 따라 증폭기(12)에서 음성신호가 소정레벨 증폭된후 콘넥터(48)에 접속된 출력트렌스(T2)를 통해 실내스피커(6)에 출력돼 승객들이 필요한 정보를 청취하는 것이다.On the other hand, in the state in which the indoor speaker 6 is connected, the voice signal is amplified by the amplifier 12 according to the driving of the relay 51, and then the indoor speaker through the output transformer T2 connected to the connector 48. It is printed on (6) and passengers listen to the necessary information.
다음에 사이드방송시,Next time you broadcast side,
사이드방송시에는 좌·우측을 구분해서 방송한다. 즉, 좌측신호는 콘넥터(46)의 4번핀, 우측신호는 콘넥터(46)의 3번핀을 통해 받으며 이때에는 트래지스터(Q13)(Q12)에 각각 베이스전류가 흘러 트랜지스터(Q13)(Q12)가 구동되므로 이 트랜지스터(Q13)(Q12)의 각각 콜렉터에 연결되어 있는 릴레이(52)(53)가 구동되고, 접점(a1, a2)(b1, b2)(c1, c2)(d1, d2)이 구동됨으로써 콘넥터(47)를 통해 좌·우츠피커가 연결되는 것이다. 여기서, 좌·우스피커의 연결을 동시에 설명하였으나, 예를 들어 중앙재어기(2)로 부터 좌측신호를 받으면 콘넥터(46)의 1, 4번핀에 100V 전압이 공급되어 트랜지스터(Q10)(Q11)(Q12)가 구동되므로 릴레이(51)(53)(54)가 각각 구동되고, 접점(a1, a2)(b1, b2)(c1, c2)을 통해 출력트랜스(T2)의 출력이 좌측스피커에 연결되는 것이다.In the case of side broadcasting, broadcasting is performed by dividing the left and right sides. That is, the left signal is received through pin 4 of the connector 46 and the right signal is received through pin 3 of the connector 46. At this time, the base current flows through the transistors Q13 and Q12, respectively. Since it is driven, the relays 52 and 53 connected to the collectors of the transistors Q13 and Q12 are respectively driven, and the contacts a1 and a2 (b1 and b2) (c1 and c2) (d1 and d2) are driven. The left and right pickers are connected by the connector 47 by being driven. Here, the connection of the left and right speakers is described at the same time. For example, when the left signal is received from the central controller 2, 100V voltage is supplied to pins 1 and 4 of the connector 46, so that the transistors Q10 and Q11 are connected. Since Q12 is driven, the relays 51, 53, and 54 are driven, respectively, and the output of the output transformer T2 is connected to the left speaker through the contacts a1 and a2 (b1 and b2) (c1 and c2). It is connected.
한편, 고장진단시에는,On the other hand, when troubleshooting
장비의 전원상태를 체크하기 위해 자동방송장치로 부터 고장진단신호를 수신받는다.Receives fault diagnosis signal from the automatic broadcasting system to check the power status of the equipment.
이때, 딥스위치(7)는 총 8개의 스위치(SW1~SW8)로 구성되어 있으므로 증폭기 1개당 1개씩 선택할 수 있다.At this time, since the dip switch 7 is composed of a total of eight switches SW1 to SW8, one dip switch 7 may be selected.
이때, 톤검출부(9) 및 채널선택부(8)에 의해 해당신호가 검출되는바, 트랜지스터(Q14)의 베이스전위가 로우레벨이 되면 릴레이(55)가 구동된다. 이에 따라 릴레이(56)가 구동되어 트랜스(T3)에 유기된 콘넥터(43)의 3, 4번핀에 유기되어 고장진단부(10)에 인가됨으로써 정상적인 전원이 공급되는지를 판단하는 것이다. 이와 같이 본 고안의 전동차방송시스템의 출력장치에 의하면, 실내방송, 좌·우 스피커선택방송은 물론 고장진단가능까지 갖추어서 간편하게 방송용 스피커를 선택 구동시킬 수 있을 뿐만 아니라, 장치의 오동작을 방지할 수 있는 등의 커다란 잇점이 있다.At this time, the corresponding signal is detected by the tone detector 9 and the channel selector 8, and the relay 55 is driven when the base potential of the transistor Q14 becomes low level. Accordingly, the relay 56 is driven to be induced on pins 3 and 4 of the connector 43 induced in the transformer T3 and applied to the failure diagnosis unit 10 to determine whether normal power is supplied. As described above, according to the output device of the electric vehicle broadcasting system of the present invention, not only the indoor broadcasting, the left and right speaker selection broadcasting, but also the fault diagnosis can be performed, and the speaker for broadcasting can be easily selected and driven, and the malfunction of the device can be prevented. There is a big advantage to being.
