The invention provides a biological monitoring device in an automobile cabin. The biological monitoring device comprises a first shell, a second shell and a PCB, the first shell covers the second shell, the PCB is arranged in the second shell, a box body is arranged on the PCB, one end of the top of the box body is provided with a mounting groove, the inner side of the mounting groove is provided with a cavity, a semi-cylinder is arranged in the cavity, and an infrared light source is arranged at one side in the cavity. According to the invention, through ventilation of fences and a connecting cloth, carbon dioxide enters the cavity, infrared rays are emitted through the infrared light source and reach a probe of the optical power meter after being reflected by the cavity and the semi-cylinder, and results measured by the probe of the optical power meter are different when infrared intensity and carbon dioxide concentration are measured by the probe of the optical power meter. Whether a life body exists in the vehicle or not is analyzed by analyzing the carbon dioxide concentration in the vehicle, the method has long-term and real-time monitoring performance, and unsafe factors are avoided.
本发明提供了一种汽车座舱内生物监测装置,包括第一壳体、第二壳体和PCB电路板,所述第一壳体盖设在所述第二壳体的上方,所述第二壳体的内部设有PCB电路板,且PCB电路板上设有盒体,所述盒体顶部的一端设有安装槽,且安装槽的内侧设有腔体,所述腔体的内部设有半圆柱体,且腔体内部的一侧设有红外光源;本发明通过阑珊和连接布透气,使得二氧化碳进入腔体内,通过红外光源发射红外线,经过腔体和半圆柱体的反射到达光功率计探头处,光功率计探头测算红外线强度,二氧化碳浓度不同,光功率计探头测的结果不同,综上,通过分析车内二氧化碳浓度来分析车内是否有生命体存在,这种方法具有长期性和实时监控性,避免不安全因素。
