Description
Technical field
The utility model relates to a kind of quality detection device of tealeaves accumulating, comprise the combination of a kind of electric nasus system of being made up of gas sensor array, electronic circuit and radio RF recognition technology, for the quality monitoring in tealeaves storage and transportation and tracking, belong to logistics warehouse equipment technical field.
Background technology
The production and processing of tealeaves has very strong seasonality, but the consumption of tealeaves but has perennially in time, spatially then has global feature.China is production and the big export country of tealeaves, the tealeaves that annual spring and summer is produced wants year-round provision to various places various countries, but the accumulating link in processing and trade process, because affect by time, environment etc. are subjective and objective, to the quality of tealeaves be had influence on, thus affect the economic worth of tealeaves as commodity.Therefore, in the long-time storage and long distance transportation process of tealeaves, particularly to the quality monitoring in famous and precious tealeaves and large tealeaves logistics progress and tracking, there is important economic implications.
Tea leaf quality factor comprises the many aspects such as color and shape, and China GB GB/T 23776-2009 and rower NY/T 787-2004 defines tealeaves sensory review condition, method and assessment result and criterion.That is tea leaf quality evaluation is the process of sense organ Comprehensive Assessment more than, and the main Shi Rengong that samples tea that relies on completes at present, and this completes automatically to the instrument and equipment of tealeaves storage and transport process is a difficult point.But from above-mentioned two standard analysiss, tealeaves smell accounts for the coefficient of 25% ~ 35% in all kinds of tea leaf quality scoring, it is the key factor determining tea leaf quality, and in the chemical composition affecting tealeaves sense of taste factor, most of volatilizable thus embody in sense of smell factor, so utilize the smell of tealeaves in storage and transport process itself to differentiate that the change of tea leaf quality is feasible, also be attainable, and to monitor with environmental factors such as general temperature, humidity, oxygen level and modeling is analyzed, more directly, easy and reliable.
Cause the factor of the quality comparison in tealeaves storage and transport process, mainly comprise the physical reaction of tealeaves itself, and temperature, humidity, oxygen level, illumination ultraviolet etc. pack internal and external environment impact.The former be by the time cause inevitable, the impact of the latter then can promote the former change, such as seal failure causes oxygen level to increase, the oxidation reactions such as the lipid in tealeaves and carotenoid are aggravated, produce rancid, and Tea Polyphenols and amino acid whose oxidation can reduce tealeaves flavour, lose may just as well fresh.The chemical reaction of tealeaves in storage and transport process relates to the change of thousands chemical composition, consumer or comment final the evaluating of tea teacher not to be the change relying on single or certain several composition, but all changes is comprehensive.
The occasion that Electronic Nose passes judgment on smell quality in " comprehensively " has its considerable advantage, the information that the gas sensor array of common wide spectrum sensitivity obtains by it, by certain pattern-recognition intelligence means, the information of the tested tealeaves of comprehensive descision, and without the need to paying close attention to smell kind and each component concentration.This feature makes it than analytical instrument such as gaseous mass spectrums, simpler and cheap, and miniaturization is even microminiaturized.And wireless radio-frequency (RFID) has been paid attention in logistics field at present, for goods in the tracking of the processes such as packaging, storage, dispensing and management.RFID utilizes special reader to be read by the electronic tag internal information depended on goods, and without the need to setting up machinery or optical contact between recognition system and specific goods, very convenient and reliable.
The low volume data that Simple electronic nose obtains by the follow-up of quality device of tealeaves accumulating and the logistics information of goods own are stored in the storage chips such as EEPROM or FLASH, the quality information of tealeaves in packaging can be obtained at any time by reader in storage and transport process, for tealeaves accumulating environmental Kuznets Curves provides reference information, also can be used as dealer or consumer and the quality of this commodity tealeaves is traced to the source use fast.
Summary of the invention
The purpose of this utility model is the quality detection device of the tealeaves accumulating provided in the storage of a kind of tealeaves and transportation.For this reason, the utility model adopts following technical scheme:
The utility model is made up of Simple electronic nasus system and less radio-frequency module for reading and writing,
Described Simple electronic nasus system comprises gas sensor array and electronic circuit and data acquisition module;
Gas sensor array comprises 2 ~ 4 normal temperature gas sensors;
