[0003] Aquatic products sold on the market are mainly in the form of air-conditioning and tray packaging. Due to its high nutrition, high quality and easy acceptance by consumers, it enters the consumer market as a high-end product. Therefore, the requirements for fresh-keeping packaging of aquatic products tend to be small. However, due to the large size and high power consumption of traditional sensors based on PCB boards, it is difficult to monitor aquatic products in terms of transportation, storage, packaging, and sales.

An embodiment of the invention provides a multi-parameter passive flexible sensing device and a multi-parameter passive flexible sensing method for aquatic product quality monitoring. The multi-parameter passive flexible sensing device comprises a loop antenna, an RFID tag chip, a multi-parameter sensing module, an energy acquisition circuit, a microcontroller, a flexible substrate, an interface circuit and a color trigger detection device. The multi-parameter passive flexible sensing device and the multi-parameter passive flexible sensing method provided by the embodiment of the invention have the advantages of passivity, miniaturization, flexibility, high precision and low energy consumption; the volume size of a monitoring device is effectively reduced and the monitoring device is easily attached inside a package; the RGB color intensity optically responded by each gas sensor in the multi-parameter sensing module is detected through using the color triggering detection device; and by utilizing wireless radio frequency modules of sensor nodes, the real-time transmission and communication of key parameter data of the microenvironment are realized, and the real-time intelligent monitoring of the quality of aquatic products is realized.
Description
technical field [0001] The invention relates to the technical field of sensors and data processing, and more specifically, to a multi-parameter passive flexible sensing device and method for quality monitoring of aquatic products. Background technique [0002] Aquatic products are easily infected by spoilage bacteria and pathogenic bacteria in the process of cold chain logistics. Changes in gases (hydrogen sulfide, ammonia and amines, ethanol and organic solvent gases) and exogenous gases (gases injected for freshness preservation such as nitrogen) will seriously affect the quality and safety of aquatic products. Therefore, it is urgent to control temperature, Oxygen, ammonia and other key parameters for data monitoring, collection, transmission and processing. [0003] Aquatic products sold on the market are mainly in the form of air-conditioning and tray packaging. Due to its high nutrition, high quality and easy acceptance by consumers, it enters the consumer market as a...
