Abstract
본 발명은 임의의 하드웨어 장치에서 발생되어 송출되는 경보신호의 발생시 이의 전위 여부를 판단하기 위한 전전자 교환기의 경보 확인 장치에 관한 것으로서, 다수의 경보신호를 수신하여 경보상태의 발생 여부를 판단하는 신호를 출력하는 경보신호 수신 및 풀업(Pull-up)저항부와, 상기 경보신호 수신 및 풀업 저항부로 부터 출력되는 신호에 따라 LED(Light Emitting Diode)를 구동시키는 LED구동부와, 상기 LED구동부의 제어에 따라 점등되는 다수의 LED(L1-L8)로 구성된 LED부를 포함한다. 따라서 별도의 계측장비 없이 손쉽게 발생경보의 진위 여부를 판별할 수 있다.The present invention relates to an alarm confirmation device of an electronic switchboard for determining whether or not an electric potential thereof is generated when an alarm signal generated and transmitted by an arbitrary hardware device is generated. Alarm signal reception and pull-up resistor unit for outputting the LED, LED driver for driving the LED (Light Emitting Diode) according to the signal output from the alarm signal reception and pull-up resistor unit, and the LED driver control It includes an LED unit consisting of a plurality of LED (L1-L8) to be lit. Therefore, it is possible to easily determine the authenticity of the generated alarm without a separate measuring equipment.
