Ethylene gas content monitoring device and method

Abstract

The invention provides an ethylene gas content monitoring device and method. The device includes a control unit, an information acquisition unit, an A / D conversion unit, a clock unit and a storage unit. The information acquisition unit is used for real-time acquisition of an ethylene gas analog signal. The A / D conversion unit is used to convert an ethylene gas analog signal into a digital signalto obtain the ethylene gas content; the clock unit is used for recording the corresponding acquisition time when the information acquisition unit collects the ethylene gas content; and the control unit is used to control the acquisition process of the information acquisition unit and the recording process of the clock unit, also used to obtain the ethylene gas content and the corresponding acquisition time, and send the ethylene gas content and the corresponding acquisition time to the storage unit. The ethylene gas content in the cold chain logistics of fruits and vegetables can be recorded in real time. The device facilitates the establishment of changes in the ethylene gas content over time in the cold chain transportation of the fruits and vegetables, and provides a theoretical basis for the cold chain transportation and storage technology of the fruits and vegetables.

Description

technical field [0001] The invention relates to the technical field of cold chain logistics, and more specifically, to an ethylene gas content monitoring device and method. Background technique [0002] Due to the characteristics of high water content, easy damage and easy to rot and deterioration of fruit and vegetable crops, there are physiological phenomena such as respiration and ethylene ripening after picking. During storage or cold chain logistics transportation, due to their own respiration and the influence of the environment , the ethylene gas produced by fruits and vegetables will gradually increase, leading to quality problems such as pulp browning and fruit rot in fruits and vegetables. [0003] With the economic development of developed countries and people's increasing requirements for food quality, people pay more attention to cold chain transportation. The monitoring and management of ethylene gas content in traditional cold chain transportation mainly relie...

Problems solved by technology

[0003] With the economic development of developed countries and people's increasing requirements for food quality, people pay more attention to cold chain transportation. The monitoring and management of ethylene gas content in traditional cold chain transportation mainly relies on manual measurement and paper records, although it can be Realize the measurement of ethylene gas content, but it can only realize manual measurement and recording at individual time points, and cannot realize real-time monitoring during cold chain transportation. When problems occur, they can only be found after the fact, and cannot be timely correct the problem

At the same time, the workload of the staff increases, which is not conducive to the follow-up work
