Zusammenfassung:	The present invention relates to a multi-functional measuring device, and more particularly, to a multi-functional measuring device attached to a safety helmet, which is attached to a safety helmet to measure various working environment factors inside a sealed space where a worker works, and notifies the same to the worker to prevent an accident. According to the present invention, the multi-functional measuring device attached to a safety helmet comprises: a body placed on an upper surface of a brim of a front surface of a safety helmet; a clip means provided on a bottom surface of the body to clamp the brim with a predetermined elastic force so as to fix the body; an oxygen concentration sensor provided in the body, and receiving power of a predetermined battery to measure the concentration of oxygen in air; an LPG sensor provided in the body, and receiving the power of the battery to detect LPG; a lamp for receiving the power of the battery to illuminate the front of the safety helmet; a buzzer for receiving the power of the battery, and generating a warning sound by a predetermined control signal; a flickering control unit for receiving the power of the battery to repeatedly flicker the lamp by the predetermined control signal; and a main control unit provided in the body, and receiving the power of the battery to transmit a control signal to the buzzer and the flickering control unit when a monitoring signal is received from the oxygen concentration sensor and the LPG sensor in case that the concentration of oxygen measured by the oxygen concentration sensor is a reference value or less, or LPG is sensed by the LPG sensor. 본 발명은 다기능 측정기에 관한 것으로서, 더욱 상세하게는 안전모에 부착하여 작업자가 작업하는 밀폐공간 내부의 다양한 작업환경 요인들을 측정하여 작업자에게 알려주어 안전사고를 예방할 수 있는 안전모 부착형 다기능 측정기에 관한 것이다. 본 발명에 따른 안전모 부착형 다기능 측정기는 안전모의 전면 모자챙의 상면에 놓이는 본체와; 상기 본체의 저면에 구비되어 상기 모자챙을 소정 탄성력으로 집어 상기 본체를 고정하는 클립수단과; 상기 본체에 구비되고 소정 배터리의 전력을 공급받아 공기 중의 산소 농도를 측정하는 산소농도센서와; 상기 본체에 구비되고 상기 배터리의 전력을 공급받아 LPG가스를 감지하는 LPG 감지센서와; 상기 배터리의 전력을 공급받아 상기 안전모의 전방을 밝히는 램프와; 상기 배터리의 전력을 공급받아 소정 제어신호에 의해 경고음을 발생시키는 부저와; 상기 배터리의 전력을 공급받아 소정 제어신호에 의해 상기 램프를 반복적으로 점멸하는 점멸제어부와; 상기 본체에 구비되고 상기 배터리의 전력을 공급받아 상기 산소농도센서에 의해 측정된 산소 농도가 기준치 이하이거나, LPG 감지센서에 의해 LPG가 감지되어 상기 산소농도센서와 상기 LPG 감지센서로부터 감시신호를 수신받으면, 상기 부저와 상기 점멸제어부에 제어신호를 송신하는 메인제어부를 포함하여 이루어진다.
