본 고안은 건전지를 사용하는 휴대용 라디오 등과같은 각종 전자기기에 있어서, 건전지의 교환을 자동으로 경보하는 건전지교환 자동경보회로에 관한 것이다.The present invention relates to a battery replacement automatic alarm circuit that automatically alarms the replacement of batteries in various electronic devices such as portable radios using batteries.
건전지는 그 자체의 전원을 사용하지 않아도 자연열화하여 전원이 소모되고 노화하게 되며, 건전지가 노화될 경우에는 내부에 충진되었던 전해액이 외부로 흘러나와 건전지가 접촉되는 접촉단자는 물론 기기의 내부를 부식시키게 되므로 건전지는 전원이 소모되어 노화되기 전에 기기의 건전지수납함에서 빼내어야 한다.Batteries deteriorate even when they do not use their own power source, which consumes power and ages.When the battery ages, the electrolyte filled inside flows out to the outside, and the contact terminals contacting the battery are corroded. Batteries should be removed from the battery compartment of the unit before they are depleted and aged.
그러나 종래의 건전지를 사용하는 각종 기기들은 건전지수납함에 내장한 건전지의 전원이 소모되어 노화될 경우에 이를 경보하는 수단이 구비되어 있지 않았다. 그러므로 사용자들은 기기에 건전지를 내장하여 둔 상태에서 그대로 방치해두고, 이로 인하여 건전지가 노화되어 내부의 전해액이 흘러나오고, 건전지의 접촉단자 및 기기의 내부를 부식시켜 그 사용수명을 단축시키는 경우가 빈번히 발생되었다.However, various devices using a conventional battery are not provided with a means for alarming when the power of the battery built in the battery box is depleted due to aging. Therefore, users should leave the battery inside the device as it is, and this causes the battery to age and flow out of the electrolyte, and the contact terminals of the battery and the inside of the device are often corroded to shorten its service life. Occurred.
따라서, 본 고안의 목적은 건전지의 전원이 소모되었을 경우에 이를 경보하여 건전지를 교환하게 하는 건전지교환 자동경보회로를 제공하는데 있다.Accordingly, it is an object of the present invention to provide an automatic battery replacement alarm circuit for alerting when a battery power is exhausted to replace the battery.
이와같은 목적을 가지는 본 고안은 교류전원의 정류전원 또는 건전지의 전원을 부하에 동작전원으로 공급하고, 충전부가 축전지에 충전시켜 두고, 건전지가 내장되는 건전지수납함에는 건전지의 내장 및 이탈에 따라 동작되는 리프스위치를 설치한다.The present invention having such a purpose is to supply the rectified power of the AC power supply or the power of the battery to the load as the operating power, the charging unit is charged to the storage battery, the battery storage in which the battery is built is operated according to the built-in and detachment of the battery Install the leaf switch.
건전지가 내장되어 리프스위치가 접속될 경우에는 경보부가, 건전지의 전원과 축전지의 충전전원을 비교하여 건전지의 전원이 일정값 이하로 되는 지를 판별하고, 건전지의 전원이 일정값 이하로 될 경우에는 경보부가 축전지의 충전전원으로 부저를 구동시키고 발광다이오드를 점등시켜 건전지의 교환을 경보하게 된다.When the leaf switch is connected with the built-in battery, the alarm unit compares the power supply of the battery with the charging power of the battery to determine whether the power supply of the battery falls below a certain value. The buzzer is driven by the charging power of the additional battery, and the light emitting diode is turned on to alert the replacement of the battery.
이하, 본 고안의 자동 경보회로의 바람직한 실시예를 보인 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, with reference to the accompanying drawings showing a preferred embodiment of the automatic alarm circuit of the present invention will be described in detail.
제 1 도는 본 고안의 자동경보회로의 실시예를 보인 상세도로서 이에 도시된 바와같아. 교류전원(AC)을 정류하여 부하에 동작전원으로 공급하는 트랜스(T), 브리지다이오드(BD) 및 콘덴서(C1)로 된 전원부(10)와, 상기 전원부(10)가 동작전원을 공급하지 않을 경우에 건전지(DEB)의 전원을 동작전원으로 공급하는 저항(R1-R3) 및 트랜지스터(Q1)로 된 건전지 전원제어부(20)와, 부하로 공급되는 전원의 일부를 저장하여 경보용 전원으로 출력하는 저항(R4, R5), 콘덴서(C2, C3), 트랜지스터(Q2), 다이오드(D1-D3) 및 축전지(BAT)로 된 경보전원 충전부(30)와, 상기 경보전원 충전부(30)의 출력전원 및 건전지(DEB)의 전원이 일정값 이하로 소모될 경우에 이를 경보하는 저항(R6-R9), 트랜지스터(Q3), 발광다이오드(LD), 다이오드(D4) 및 부저(41)로 된 경보부(40)와, 건전지 수납함에 건전지(DEB)가 내장되어 있는지를 검출하여 상기 경보부(40)의 동작을 제어 하는 리프스위치(50)로 구성하였다.1 is a detailed view showing an embodiment of the automatic alarm circuit of the present invention as shown therein. A power supply unit 10 consisting of a transformer (T), a bridge diode (BD), and a capacitor (C1) for rectifying the AC power supply (AC) and supplying the load as an operating power source, and the power supply unit (10) does not supply the operating power supply. In this case, the battery power control unit 20 including resistors R1-R3 and transistors Q1 for supplying the power of the battery DEB to the operating power and a part of the power supplied to the load are stored and output as alarm power. The alarm power charging unit 30 comprising the resistors R4 and R5, the capacitors C2 and C3, the transistors Q2, the diodes D1-D3, and the battery BAT, and the output of the alarm power charging unit 30 Alarm unit consisting of resistors (R6-R9), transistors (Q3), light-emitting diodes (LD), diodes (D4), and buzzers (41) to alert when the power source and battery (DEB) are consumed below a certain value. 40 and a leaf switch 50 which detects whether the battery DEB is built in the battery compartment and controls the operation of the alarm unit 40. It was constructed.
상기에서 리프스위치(50)는 제 2 도에 도시된 바와같이 건전지 수납함에 건전지(DEB)를 내장하였을 경우에 접속되고, 내장하지 않을 경우에는 개방되게 설치한다.In the above, the leaf switch 50 is connected when the battery DEB is built in the battery compartment as shown in FIG.
이와같이 구성된 본 고안은 건전지수납함에 건전지(DEB)가 내장된 상태에서 교류전원(AC)이 인가되면, 인가된 교류전원(AC)은 전원부(10)의 트랜스(T)를 통해 강압되고, 브리지 다이오드(BD)를 통해 브리지 정류되며, 콘덴서(C1)에 의해 평활된 후 부하에 동작전원으로 공급된다.According to the present invention configured as described above, when AC power is applied while the battery DEB is built in the battery storage box, the applied AC power AC is stepped down through the transformer T of the power supply unit 10, and a bridge diode The bridge is rectified through the BD, smoothed by the capacitor C1, and then supplied to the load as an operating power source.
또한, 전원부(10)의 출력전원이 건전지 전원제어부(20)의 저항(R1, R2)을 통해 트랜지스터(Q1)의 베이스에 인가된다.In addition, the output power of the power supply unit 10 is applied to the base of the transistor Q1 through the resistors R1 and R2 of the battery power supply control unit 20.
여기서, 트랜지스터(Q1)에 그의 바이어스전압 이하가 인가되게 저항(R1-R3)의 값을 설정하면 트랜지스터(Q1)는 계속 오프상태를 유지하게 되므로 건전지(DEB)의 전원은 부하게 공급되지 않는다.Here, when the value of the resistors R1-R3 is set such that the bias voltage is applied to the transistor Q1 or less, the transistor Q1 is kept in an off state, and thus the power of the battery DEB is not supplied poorly.
그리고, 교류전원(AC)이 인가되지 않을 경우에는 전원부(10)에서 출력되는 전원이 없고, 트랜지스터(Q1)의 베이스전류가 저항(R2, R3)을 통해 접지로 흐르게 되므로 건전지(DEB)의 전원이 트랜지스터(Q1)를 통해 부하로 공급된다.When the AC power source AC is not applied, there is no power source output from the power supply unit 10, and the base current of the transistor Q1 flows to ground through the resistors R2 and R3. It is supplied to the load through this transistor Q1.
이와같은 상태에서 부하로 공급되는 전원이 경보전원충전부(30)의 저항(R4, R5)을 통해 트랜지스터(Q2)의 베이스에 인가되어 그가 온되므로 부하가 공급되는 동작 전원의 일부가 저항(R4) 및 트랜지스터(Q2)를 통해 축전지(BAT)에 경보용 전원으로 충전되어 경보부(40)의 저항(R8)을 통해 트랜지스터(Q3)에 에미터에 인가된다.In this state, the power supplied to the load is applied to the base of the transistor Q2 through the resistors R4 and R5 of the alarm power charging unit 30 and turned on so that a part of the operating power supplied with the load is the resistor R4. And the battery BAT is charged with an alarm power supply through the transistor Q2 and applied to the emitter to the transistor Q3 through the resistor R8 of the alarm unit 40.
그리고, 건전지(DEB)를 건전지 수납함에 내장함에 따라 리프스위치(50)가 접속되므로 건전지(DEB)의 전원이 저항(R6, R7)에 의해 분할되어 트랜지스터(Q3)의 베이스에 인가된다. 여기서, 건전지(DEB)의 전원이 충분하여 트랜지스터(Q3)의 베이스에 인가되는 전원이 그의 에미터에 인가되는 전원보다 높게되면, 트랜지스터(Q3)가 오프되므로 부저(41) 및 발광다이오드(LD)는 동작하지 않게된다. 그리고, 건전지(DEB)의 전원이 일정값이하로 소모되어 트랜지스터(Q3)의 베이스에 인가되는 전원이 그의 에미터에 인가되는 전원보다 낮을 경우에는 트랜지스터(Q3)가 온되므로 축전지(BAT)의 전원이 저항(R8) 및 트랜지스터(Q3)를 통해 부저(41) 및 발광다이오드(LD)에 인가되어 부저(41)가 경보음을 출력하고, 발광다이오드(LD)가 점등되어 건전지(DEB)의 교환을 경보하게 된다. 이때, 다이오드(D4)는 역방향방지용 스위칭 다이오드로 동작하여트랜지스터(Q3)의 베이스 전류가 건전지(DEB)를 내장하지 않았을 경우에는 리프스위치(50)가 개방되므로 트랜지스터(Q3)의 베이스 전류가 흐르지 않게되어 트랜지스터(Q3)는 계속 오프 상태를 유지하게 되고, 부저(41) 및 발광다이오드(LD)는 동작하지 않게된다.Since the leaf switch 50 is connected as the battery DEB is incorporated in the battery storage box, the power of the battery DEB is divided by the resistors R6 and R7 and applied to the base of the transistor Q3. Here, when the power supply of the battery DEB is sufficient and the power applied to the base of the transistor Q3 is higher than the power applied to the emitter thereof, the transistor Q3 is turned off, so the buzzer 41 and the light emitting diode LD are turned off. Will not work. When the power of the battery DEB is consumed below a certain value and the power applied to the base of the transistor Q3 is lower than the power applied to the emitter thereof, the transistor Q3 is turned on, so the power of the storage battery BAT is turned on. The resistor R8 and the transistor Q3 are applied to the buzzer 41 and the light emitting diode LD so that the buzzer 41 outputs an alarm sound, and the light emitting diode LD is turned on to replace the battery DEB. Will alert you. At this time, the diode D4 operates as a reverse prevention switching diode so that when the base current of the transistor Q3 does not include the battery DEB, the leaf switch 50 is opened so that the base current of the transistor Q3 does not flow. As a result, the transistor Q3 remains in the off state, and the buzzer 41 and the light emitting diode LD do not operate.
이상에서 상세히 설명한 바와같이, 본 고안은 축전지에 경보용 전원을 충전시켜두고, 건전지의 전원이 일정값 이하로 되어 노화될 경우에 이를 경보하여 건전지를 교환하도록 함으로써 건전지가 노화되어 전해액이 누출되고, 누출된 전해액에 의해 건전지의 접촉단자 및 기기의 내부가 부식되는 것을 미연에 방지하고, 기기의 사용수명을 연장할 수 있는 효과가 있다.As described in detail above, the present invention charges the power supply for the alarm to the battery, and when the power of the battery is less than a certain value when the aging alarm to replace the battery by aging it to leak the electrolyte, It is possible to prevent corrosion of the contact terminals of the battery and the inside of the device by the leaked electrolyte and to extend the service life of the device.
