The objective of the present invention is to provide a relay-welding detection device and detection method, the device and method capable of determining, whether a relay is welded, by using an analog-digital converter (ADC). Another relay-welding detection device according to the present invention comprises: a first ADC for measuring a voltage of a relay input terminal; a second ADC for measuring a voltage of a relay output terminal; and a CPU for comparing the voltage of the relay input terminal with the voltage of the relay output terminal and determining whether the relay is welded.

    La présente invention concerne un dispositif de détection et un procédé de détection de soudage de relais, le dispositif et le procédé pouvant déterminer si un relais est soudé, à l'aide d'un convertisseur analogique-numérique (CAN). Un autre dispositif de détection de soudage de relais selon la présente invention comprend : un premier CAN pour mesurer une tension d'une borne d'entrée de relais ; un second CAN pour mesurer une tension d'une borne de sortie de relais ; et une unité centrale pour comparer la tension de la borne d'entrée de relais à la tension de la borne de sortie de relais et déterminer si le relais est soudé.

    본 발명은 ADC(Analog-digital converter)를 이용하여 계전기 융착여부를 판단할 수 있는 계전기 융착 감지장치 및 감지방법을 제공하고자 하는 데 있다. 본 발명에 다른 계전기 융착 감지장치는 계전기입력단의 전압을 측정하는 제1 ADC, 계전기출력단의 전압을 측정하는 제2 ADC 및 상기 계전기입력단의 전압과 상기 계전기출력단의 전압을 비교하여, 융착여부를 판단하는 CPU를 포함한다.
