Abstract

The invention discloses an ethylene concentration measuring and monitoring device and a measuring and monitoring method thereof. The ethylene concentration measuring and monitoring device comprises asealed box, gas sensors, temperature and humidity sensors, an ultraviolet lamp assembly, a light-transmittable cylinder, a wind power assembly and a control assembly. The ethylene concentration measuring and monitoring device uses the ordinary gas sensors for replacing high-priced ethylene sensors and uses multiple gas sensors, so that the concentration measuring accuracy is improved and the service life is prolonged; ultraviolet lamps are used for catalyzing ethylene, the ultraviolet lamps have lower energy consumption than mercury lamps, the ultraviolet lamps do not contain a common harmfulsubstance mercury in a CCFL technology, and the ultraviolet lamps have vibration-proof and impact-resistant effects and are rarely damaged, so that garbage can be reduced and the cost can be reduced;in addition, through a fitting relationship of voltage and concentration, the ethylene concentration can be accurately detected; furthermore, through decomposition of the ultraviolet lamps, the concentration can be accurately controlled, so that the intelligent control operation ability is strong and the measurement and control precision is high.

Description

technical field [0001] The invention relates to the technical field of gas detection, in particular to an ethylene concentration measurement and monitoring device and a measurement and monitoring method thereof. Background technique [0002] At present, my country's annual fruit production accounts for a quarter of the world's, and fruit storage and preservation have become important technologies. Although the content of ethylene in fruit is not very high, it is one of the important factors affecting fruit preservation. Nowadays, the technology of catalyzing the decomposition of ethylene is gradually at the forefront of fruit preservation technology. For the effect of ethylene decomposition, a special ethylene sensor is usually used to measure the ethylene concentration, and then judge. [0003] However, although the ethylene sensor has an excellent detection effect, its effective use time is short and the device cost is relatively high, so it has great defects in effective...
