Abstract

본 발명은 정전시에도 사용할 수 있도록 주전원장치와 보조전원장치를 겸비한 전화기에 있어서; 상기 전화기에 전원을 공급하는 전원이 주전원부에서 공급되는 것인지 보조전원부에서 공급되는 것인지를 판단하는 전원 구별 검출부로 구비함을 특징으로 한다. 또한, 전화기에 공급되는 전원이 주전원부 또는 보조전원부인지를 판단하는 방법에 있어서; 전화기 내부에 공급되는 전원이 주전원일 경우 표시부의 발광다이오드를 점등시키는 단계를 포함함을 특징으로 한다. 따라서, 본 발명은 전화기에 별도의 스위치회로 및 기타 회로 구성없이 알고리즘을 변경하고 하드웨어적인 기능을 간단하게 설정함으로써 정전시 보조전원장치를 사용하는 전화기에서 현재 공급되는 전원이 주전원인지 보조전원인지를 용이하게 인지되어 보조전원의 과사용으로 인한 전화기의 오동작을 방지할 수 있다.The present invention provides a telephone having a main power supply device and an auxiliary power supply device to be used even in a power failure; And a power discrimination detecting unit for determining whether power supplying power to the phone is supplied from a main power supply unit or from an auxiliary power supply unit. In addition, the method for determining whether the power supplied to the telephone is the main power supply or auxiliary power supply; And turning on the light emitting diodes of the display unit when the power supplied to the inside of the phone is the main power source. Therefore, the present invention can easily change whether the current power supplied from the telephone using the auxiliary power supply device in case of power failure by changing the algorithm and simply setting the hardware function without a separate switch circuit and other circuit configuration in the telephone. It is possible to prevent the malfunction of the phone due to overuse of auxiliary power.
