Beschreibung
Zusammenfassung:	Embodiments relate to an automatic test device which comprises: at least one switch configured to connect a sensor and a local unit to each other in a normal mode and disconnect the sensor from the local unit in a test mode; and a controller configured to transmit a simulation signal to the sensor and the local unit in the test mode and analyze a reflection signal received in response to the simulation signal to test whether a diagnosis system is abnormal. 실시 예들은 정상 모드에서 센서와 로컬 유닛을 서로 연결하고, 시험 모드에서 상기 센서와 상기 로컬 유닛의 연결을 단절하는 적어도 하나의 스위치 및 시험 모드에서 상기 센서 및 상기 로컬 유닛으로 모의 신호를 전송하고, 상기 모의 신호에 응답하여 수신되는 반사 신호를 분석하여 진단 시스템의 이상 여부를 시험하는 제어기를 포함하는, 자동 시험 장치에 관한 것이다.
