O2-CO2-T three-parameter real-time monitoring system

Abstract

The invention discloses a O2-CO2-T three-parameter real-time monitoring system. The system comprises a closed optical path which is used for enabling ultraviolet light to enter a fluorescent sensing film in a dark closed monitoring environment, a fluorescent sensing film which is produced by combining a fluorescent sensitive material and a fluorescent sensitive indicator and is used for emitting colored light after being excited by the ultraviolet light, a color sensor which is used for collecting the colored light which is emitted by the fluorescent sensing film and corresponds to the oxygen, the carbon dioxide and the temperature fluorescent sensitive indicator, converting the colored light into electric signals and transmitting the electric signals to an embedded hardware driving platform, and the embedded hardware driving platform which is used for converting the received electric signals transmitted by the color sensor into concentration and temperature values of oxygen and carbon dioxide, and transmitting the concentration and temperature values to a display module for display through a wireless communication module. With the closed optical path designed, the influence of ambient light on monitoring data can be avoided, a proper fluorescent material is explored and is adopted as a fluorescent indicator of a corresponding to-be-detected object, and therefore, it can be ensured that the to-be-detected object can be fully measured and has an optimal excitation wave band, and an optimal detection effect is realized.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to a real-time monitoring system for three parameters of oxygen, carbon dioxide and temperature. Background technique [0002] Oxygen, carbon dioxide and temperature are closely related to our life. Real-time and accurate monitoring of oxygen concentration, carbon dioxide concentration and temperature in various fields of nature plays a vital role in the progress and development of many industries. In the field of biomedicine, the real-time monitoring of oxygen concentration and carbon dioxide concentration can be used as an important monitoring indicator for critically ill patients and neonatal care and major anesthesia operations; in the field of environmental monitoring, real-time and effective monitoring of oxygen and carbon dioxide concentrations in the air is useful. Contribute to the timely monitoring of pollution sources such as automobile exhaust that pollu...
