Solve to mix gutter oil in edible oil, with the Testing and appraisal problem of gutter oil personation edible oil.
To solve the above problems, the utility model provides a kind of device based on electronic nose detection gutter oil, including smell
Finger print information collector, signal preprocessor, feature extraction and screening washer, singlechip control chip, display screen, supply unit；
Injector is further included with what smell finger print information collector was connected.
The smell finger print information collector includes gas sensor, several different gas sensors.
The pretreatments such as the signal preprocessor is filtered original signal using filter function, denoising.
The feature extraction and screening washer carry out computing to the signal after signal preprocessor processing, amplify, and into
Row screening and optimization.
The singlechip control chip utilizes pattern-recognition according to input data, and institute's sample is identified, identification knot
Fruit shows on a display screen；Qualified edible oil volatilization gas standard value parameter is implanted into the singlechip control chip.
The injector includes heating unit and sample feeding pipe.
The smell finger print information collector is electrically connected the signal preprocessor, and signal preprocessor is electrically connected feature extraction
And screening washer, signal extraction and screening washer are electrically connected singlechip control chip, singlechip control chip is electrically connected display screen.
The beneficial effects of the utility model are：The utility model provides a kind of dress based on electronic nose detection gutter oil
Put, the characteristic of volatilization gas after being heated according to edible oil to be measured, using ripe gas sensor detection technique, makes gutter oil
Detection, judge to become prone to realize, highly practical, detection accuracy is high.

Embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describe, it is clear that described embodiment is only a kind of embodiment of the utility model, rather than whole realities
Apply example.
As shown in Figure 1, the utility model provides a kind of device based on electronic nose detection gutter oil, including smell fingerprint letter
Cease collector 1, signal preprocessor 2, feature extraction and screening washer 3, singlechip control chip 4, display screen 5, supply unit.
Injector 6 is connected with smell finger print information collector 1, injector 6 includes heating unit 61 and sample feeding pipe 62, institute
State heating unit 61 to be used for heating edible oil to be measured, make gasification substance in edible oil, sample feeding pipe 62 connects smell finger print information and adopts
Storage 1, the gas that edible oil in heating unit 61 produces is imported in smell finger print information collector 1 by sample feeding pipe 62, gas
Venthole is provided with above taste fingerprint capturer, easy to which the excessive gas of generation is discharged.
Excessive moisture, sulfide, alkanes, peroxide, polymer etc. are typically contained in gutter oil, according to gutter oil
The issuable gaseous matter in heating process, chooses the sensor to material sensitives such as alkanes, vapor, sulfide,
The gas sensor is arranged in smell finger print information collector 1.Gas sensor by environment sensitive gas it is dense
Degree is converted into corresponding electric signal, then electric signal is read in memory in digital form, realizes that the real-time digital of data is shown,
Smell finger print information collector 1 is connected with signal preprocessor 2, and the electric signal that the gas that edible oil is produced converts passes to letter
Number preprocessor 2.
The smell principle design of electronic nose main analog people, electric nasus system carry out the process and Biologic Olfaction of gas identification
Identify that the process of smell is quite similar.As shown in Fig. 2, smell or gas produce necessarily by gas sensor absorption first
Signal, be then filtered by signal preprocessor 2, denoising, the pretreatment for removing base, signal is transmitted after pretreatment
To feature extraction and screening washer 3, feature extraction and screening washer 3 carry out the signal after filtering and noise reduction computing, amplification and data spy
The extraction of sign, and the screening and optimization of data characteristics are carried out, the data characteristics after screening passes to list as input data
The data of input are carried out pattern-recognition by piece machine control chip 4, and the result is shown on display screen 5 by identification.
Since edible oil boiling point is higher, it is heated using heating unit 61 in injector 6, makes material gas therein
Change, collected by sample feeding pipe 62 into smell fingerprint capturer by gas sensor in smell finger print information collector 1.It is edible
After oil is heated, pyrolytic reaction, oxidation reaction, polymerisation etc. can occur, the product of generation has：Straight-chain hydrocarbons, olefine, fat
The material such as acid, tenth of the twelve Earthly Branches purport class material, methacrylaldehyde, carbon monoxide, carbon dioxide；Due to the substantial amounts of impurity of miscella, meeting in gutter oil
The material for being different from qualified edible oil is produced, the gas that the gas produced by contrasting edible oil to be measured is produced with qualified edible oil
Parameter is compared, you can judges whether edible oil to be measured is gutter oil, and the results are shown on display screen 5.
The above is only the preferred embodiment of the present invention, it is all made according to present utility model application the scope of the claims it is equal
Deng change and modify, should all belong to the covering scope of the utility model patent.
