본 고안은 발진부에서 출력되는 초음파 신호에 따라 초음파 진동자로 흐르는 전류의 방향을 교번시켜 초음파 진동자가 초음파를 발생하게 하는 초음파 발진기에 있어서, 초음파 발진기가 정상으로 동작하여 초음파를 발생시키는 진의 여부를 바로 검출할 수 있게 한 초음파 발진기의 이상 검출회로에 관한 것이다.The present invention is an ultrasonic oscillator in which the ultrasonic oscillator generates ultrasonic waves by alternating the direction of the current flowing to the ultrasonic vibrator according to the ultrasonic signal output from the oscillator. The abnormality detection circuit of the ultrasonic oscillator which made it possible to do this is related.

종래의 초음파 발진기는 제1도에 도시된 바와같이 초음파 신호를 출력하는 저항(R1, R4), 콘덴서(C2, C3), 트랜지스터(TR1) 및 트랜스(T1)의 일차코일(T11)로 된 발진부(2)와, 상기 발진부(2)의 출력신호를 초음파 진동자(UM)에 인가하여 초음파를 출력하게 하는 저항(R5, R6), 트랜스(T1)의 이차코일(T12, T13), 트랜지스터(TR2, TR3) 및 콘덴서(C4)로 된 구동부(3)로 구성하였다.The conventional ultrasonic oscillator has a primary coil of resistors R 1 and R 4 , capacitors C 2 and C 3 , transistors TR 1 and transformers T 1 , which output ultrasonic signals as shown in FIG. 1. (T 11 ) and the secondary of the resistors (R 5 , R 6 ) and transformer (T 1 ) to apply the output signal of the oscillation unit (2) to the ultrasonic vibrator (UM) to output the ultrasonic waves. a coil (T 12, T 13), was made up of the transistor (TR 2, TR 3) and a condenser with a (C 4), driving section (3).

제1도의 도면 설명중 미설명부호 1은 전원공급부이고, BAT는 배터리이다.In FIG. 1, reference numeral 1 denotes a power supply unit, and BAT is a battery.

이와같이 구성된 종래의 초음파 발진기는 전원공급부(1)의 배터리(BAT)의 전원이 발진부(2)에 공급되면, 발진부(2)는 콘덴서(C2,C3) 및 트랜스(T1)의 일차코일(T11)의 리액턴스에 따라 발진 즉, 발진부(2)는 콜피츠(Colpitts)발진부로 구성도어 있고, 그 발진주파수(f0)는 다음의 식과 같다.In the conventional ultrasonic oscillator configured as described above, when the power of the battery BAT of the power supply unit 1 is supplied to the oscillator 2, the oscillator 2 is the primary coil of the capacitors C 2 and C 3 and the transformer T 1 . According to the reactance of (T 11 ), the oscillation part, that is, the oscillation part 2 is composed of a Colpitts oscillation part, and the oscillation frequency f 0 is expressed by the following equation.

그리고, 발진부(2)의 발진신호는 트랜스(T1)의 일차코일(T11)에서 이차코일(T12)(T13)로 유도되고, 이때 이차코일(T12)(T13)은 서로 다른 방향으로 권선되어 발진신호가 반대방향으로 유도되며, 이와같이 이차코일(T12)(T13)로 유도된 발진신호는 저항(R5,R6)을 통해 트랜지스터(TR2,TR3)의 베이스에 인가되어 트랜지스터(TR2, TR3)가 상호간 교대로 온오프를 반복하면서 초음파 진동자(UM)가 진동하게 된다. 즉, 트랜지스터(TR2)가 온될 경우에는 전원단자(Vcc)의 전원이 트랜지스터(TR2)를 통해 콘덴서(C4)에 충전되면서 초음파 진동자(UM)로 일정전류가 흐르게 되고, 트래지스터(TR3)가 온될 경우에는 콘덴서(C4)가 온될 경우와는 반대 방향으로 전류가 흐르게 되며, 이와같이 초음파 진동자(UM)로 흐르는 전류가 교번됨에 따라 초음파 진동자(UM)는 진동하여 초음파를 출력하게 된다.In addition, the oscillation signal of the oscillator 2 is induced from the primary coil T 11 of the transformer T 1 to the secondary coil T 12 (T 13 ), wherein the secondary coils T 12 (T 13 ) are mutually The oscillation signal is wound in the other direction and the oscillation signal is induced in the opposite direction. Thus, the oscillation signal induced by the secondary coils T 12 and T 13 is transferred to the transistors TR 2 and TR 3 through the resistors R 5 and R 6 . The ultrasonic vibrator UM vibrates while being applied to the base while the transistors TR 2 and TR 3 alternately turn on and off each other. That is, when the transistor TR 2 is turned on, the power of the power supply terminal Vcc is charged to the capacitor C 4 through the transistor TR 2 , and a constant current flows to the ultrasonic vibrator UM, and the transistor TR 3 ) If the current is flowing in the opposite direction than when the capacitor (C 4 ) is turned on, as the current flowing to the ultrasonic vibrator (UM) is alternating, the ultrasonic vibrator (UM) vibrates to output the ultrasonic wave. .

그러나, 이와같은 종래의 초음파 발진기는 초음파 진동자가 진동하여 출력하는 초음파의 주파수가 보통 28KHz정도로 사람이 들을 수 있는 가청주파보다 주파수가 매우 높으므로 사용자는 별도의 기구를 사용하지 않고 소음파 발진기가 정상으로 동작하여 초음파를 출력하는지의 여부를 판별할 수 없는 결함이 있었다.However, in the conventional ultrasonic oscillator, the frequency of the ultrasonic wave vibrated by the ultrasonic vibrator is about 28 kHz, so the frequency is much higher than the audible frequency that can be heard by the user. There was a defect that can not be determined whether or not to output the ultrasonic wave by operating.

본 고안은 이와같은 종래의 결함을 감안하여, 사용자의 선택에 따라 초음파 발진기가 가청주파신호를 출력하게 하여 초음파 발진기가 정상으로 동작하는 지의 여부를 바로 검출할 수 있게 함은 초음파 진동자의 이상유무를 표시하게 안출한 것으로 이를 첨부된 제2도의 도면을 참조하여 상세히 설명하면 다음과 같다.The present invention allows the ultrasonic oscillator to output an audible frequency signal according to the user's choice in order to detect whether the ultrasonic oscillator is operating normally. The present invention will be described in detail with reference to the accompanying drawings of FIG. 2 as follows.

제2도는 본 고안의 회로도로서, 이에 도시한 바와같이 전원공급부(1)가 동작전원을 공급함에 따라 발진부(2)가 발진하여 초음파신호를 출력하고, 그 초음파신호에 따라 구동부(2)가 초음파진동자(UM)를 진동시켜 초음파를 출력하게 한 초음파 발진기에 있어서, 상기 발진부(2)의 콘덴서(C2)에 직렬로 접속된 스위치(SW1) 및 콘덴서(C5)를 병렬로 접속하여 스위치(SW1)를 단락시킴에 따라 발진부(3)가 가청주파신호를 출력하게 하고, 상기 구동부(3)의 출력단자와 초음파 진동자(UM)의 접속점을 저항(R7)을 통한 후, 서로 반대방향으로 접속된 발광다이오드(LED1)(LED2)에 접속하여 구성한 것이다.2 is a circuit diagram of the present invention. As shown in FIG. 2, the oscillation unit 2 oscillates and outputs an ultrasonic signal as the power supply unit 1 supplies operating power, and the driving unit 2 generates ultrasonic waves according to the ultrasonic signal. In the ultrasonic oscillator which vibrates the vibrator UM and outputs ultrasonic waves, the switch SW 1 and the condenser C 5 connected in series to the condenser C 2 of the oscillator 2 are connected in parallel to the switch. By shorting (SW 1 ), the oscillation unit 3 outputs an audible frequency signal, and the output terminal of the driving unit 3 and the connection point of the ultrasonic vibrator UM through the resistor R 7 and then opposite each other. The light emitting diodes LED 1 and LED 2 connected in the directions are formed.

이와같이 구성된 본 고안은 전원공급부(1)의 전원이 발진부(2) 및 구동부(3)에 공급되면, 종래와 같이 발진부(2)는 트랜지스터(TR1)가 온.오프를 반복하면서 콘덴서(C2,C3)의 값 및 트랜스(T1)의 일차코일(T11)의 리액턴스에 따라 초음파 신호를 발생하고, 그 초음파 신호를 트랜스(T1)의 이차코일(T12)(T13)로 유도된 후 트랜지스터(TR2)(TR3)의 베이스에 인가되어 트랜지스터(TR2)(TR3)가 교대로 온 및 오프를 반복하여, 트랜지스터 (TR2)(TR3)의 온 및 오프에 따라 초음파 진동자(UM)로 흐르는 전류의 방향이 교번되어 초음파 진동자(UM)가 진동하고, 초음파를 출력하게 된다.When the power supply of the power supply unit 1 is supplied to the oscillation unit 2 and the driving unit 3, the present invention configured as described above, the oscillation unit 2, as in the prior art, the transistor (TR 1 ) is repeatedly turned on and off the capacitor (C 2) , the secondary coil of the C 3) value and the transformer (T 1) the primary coil (T 11) the ultrasound signal generating a, and the ultrasound signal a transformer (T1) in accordance with the reactance of the (T 12) (leading to T 13) the later is applied to the base of the transistor (TR 2) (TR 3) by repeating the on and off the transistor (TR 2) (TR 3) alternately, in accordance with the on and off of the transistor (TR 2) (TR 3) The direction of the current flowing through the ultrasonic vibrator UM is alternately altered so that the ultrasonic vibrator UM vibrates and outputs ultrasonic waves.

그리고, 콘덴서(C4)에 전류가 흐름에 따라 저항(R7)으로 일정전류가 흐르게 되고, 발광다이오드(LED1)(LED2)로 일정전류가 흐르게 되므로 발광다이오드(LED1)(LED2)가 점등되어 초음파 진동자(UM)가 정상으로 진동함을 표시하게 된다.Then, the capacitor (C 4) according to the current flow in and flow resistance to a constant current (R 7), light emitting diode (LED 1) (LED 2) is a constant current, so the light emitting diode to flow to the (LED 1) (LED 2 ) Is turned on to indicate that the ultrasonic vibrator (UM) vibrates normally.

이와같이 동작되는 상태에서 초음파 발진기가 정상으로 동작되는지를 검출하기 위하여 스위치(SW1)를 단락시키면, 콘덴서(C5)가 콘덴서(C2)와 병렬로 접속되게 되므로 발진부(2)의 발진주파수(f0)는 다음과 같게 된다.When the switch SW 1 is short-circuited in order to detect whether the ultrasonic oscillator operates normally in this state, the capacitor C 5 is connected in parallel with the capacitor C 2 so that the oscillation frequency of the oscillator 2 f 0 ) becomes

여기서, 발진주파수(f0)가 가청주파수를 되게 콘덴서(C5)의 값을 설정하면, 발진부(2)는 가청주파신호를 출력하고, 그 가청주파신호는 트랜스(T1)의 일차코일(T11)에서 이치코일(T12)(T13)로 유도된후 저항(R5)(R6)을 통해 트랜지스터(TR2)(TR3)의 베이스에 인가되므로 트랜지스터(TR2)(TR3)는 가청주파신호에 따라 상호교대로 온오프를 반복하여 초음파 진동자(UM)로 흐르는 전류의 방향을 교번 즉, 초음파 진동자(UM)에는 가청주파신호의 주기로 전류의 방향이 교번되고, 이에 따라 초음파 진동자(UM)가 가청주파신호를 출력하여 사용자는 초음파 진동자(UM)가 출력하는 가청주파신호를 청취하면서 초음파발진기가 정상동작되는지를 판별할 수 있게 된다.Here, when the value of the capacitor C 5 is set so that the oscillation frequency f 0 becomes the audible frequency, the oscillator 2 outputs an audible frequency signal, and the audible frequency signal is the primary coil of the transformer T 1 . T 11 ) is induced into the ichicoil T 12 (T 13 ) and then applied to the base of the transistors TR 2 (TR 3 ) through the resistors R 5 (R 6 ), so that the transistors TR 2 (TR 3 ) alternately turns on and off alternately in accordance with the audible frequency signal to alternate the direction of the current flowing through the ultrasonic vibrator UM, that is, the ultrasonic vibrator UM alternates the direction of the current in the period of the audible frequency signal. The ultrasonic vibrator UM outputs the audible frequency signal so that the user can determine whether the ultrasonic oscillator is normally operated while listening to the audible frequency signal output by the ultrasonic vibrator UM.

한편, 상기와 같이 초음파 발진기가 정상 동작하여 초음파 진동자(UM)가 초음파를 출력하는 상태에서 초음파 진동자(UM)의 손상등으로 인하여 초음파 진동자(UM)로 흐르는 전류가 증가하면, 초음파 진동자(UM)로 흐르는 전류가 증가함에 따라 상대적으로 저항(R7)으로 흐르는 전류가 감소하고, 발광다이오드(LED1, LED2)로 흐르는 전류가 감소하게 되므로 발광다이오드(LED1, LED2)는 점등되지 않고, 초음파 진동자(UM)의 이상을 표시하게 된다.On the other hand, if the current flowing to the ultrasonic vibrator (UM) increases due to damage of the ultrasonic vibrator (UM) in the state in which the ultrasonic oscillator (UM) outputs the ultrasonic wave as normal operation as described above, the ultrasonic vibrator (UM) As the current flowing to the light emitting diode R 1 decreases relatively, the current flowing to the light emitting diodes LED 1 and LED 2 decreases, so that the light emitting diodes LED 1 and LED 2 are not turned on. The abnormality of the ultrasonic vibrator UM is displayed.

이상에서 상세히 설명한 바와 같이 본 고안은 간단히 초음파 발진기가 정상으로 동작되는지의 여부를 검출할 수 있음은 물론 초음파 지동자(UM)의 이상유무를 바로 알 수 있는 효과가 있다.As described in detail above, the present invention can simply detect whether the ultrasonic oscillator is normally operated, as well as have an effect of immediately knowing whether there is an abnormality of the ultrasonic wave operator UM.
