【Background technology】
With the improvement of people's living standards and society progress, people to food requirement more and more higher, particularly to fish
Class product.The freshness of Fish directly determines the desire to purchase of people.Whether many youngsters are often new to fish products
Fresh no experience, has the crowd of color weakness or achromatopsia especially for some.For this part population, how to select fresh
Fish products are extremely difficult things.
China pays much attention to the safety problem of food at present, for the quality of aquatic products has relevant departments and sets accordingly
It is standby to go detection.But, the kind equipment can only detect the quality of aquatic products, and such as aquatic products whether there is unsafe liquid medicine of immersion etc.,
But the freshness of aquatic products can not be detected.Additionally, such equipment operation is loaded down with trivial details, it is difficult to carry with and is unable to real-time detection.
For the detection of fish products freshness, there is no at present it is a kind of can simple operationss, Simple portable and real-time detection equipment.
【The content of the invention】
The purpose of the present invention is for the deficiencies in the prior art, there is provided a kind of fish freshness optical detection apparatus.
Solve above-mentioned technical problem to adopt the following technical scheme that：
This fish freshness optical detection apparatus, including light source, lens, optical filter, RGB light sensor, Wei Chu
Reason device and display lamp；Light source, RGB light sensor, display lamp are connected with microprocessor respectively；Light source projects light is to treating
On the fish body of detection fish, flake or the fish gill, its reflection light is through lens entrance to RGB light sensor；When the light of light source
When line projects the fish gill of fish to be detected, optical filter is enabled, RGB light sensor only only records the light of Jing fishes gill reflection
Retain the light of cerise wave band, filter off the light of other color bands；When the light of light source projects fish body or flake not
Optical filter is enabled, RGB light sensor records the reflection light of RGB three wave bands of light；Microprocessor obtains RGB
The signal of three passages of RGB received on light sensor, is entered by color corresponding with fish to be detected and monochrome information
Row compares and analyzes, and so as to obtain the freshness information of fish to be detected, shows the fresh of fish to be detected finally by display lamp
Degree.
This fish freshness optical detection apparatus, light source are the light being made up of red, green, blue three-color LED and collimating lens
Origin system, the light that red, green, blue three-color LED is launched are irradiated to be detected through the hot spot that collimating lens project three mixture of colours
On the fish body of fish, flake or the fish gill；The imaging system that described lens are made up of 1-30 piece lens, lens are by fish body, flake
Or the light collection reflected on the fish gill is on RGB light sensor；It is 590nm- that described optical filter only allows wave-length coverage
The light transmission of the scarlet color bands of 630nm；Described display lamp is made up of the 1-50 LED light for arranging from top to bottom,
LED light represents the different freshness of fish to be detected from top to bottom successively.
This fish freshness optical detection apparatus, described microprocessor will be received on RGB light sensor
The signal of three passages of RGB carries out spectrum analyses, filters off background signal so as to obtain the useful signal of light source corresponding band,
And the Fish standard comparison information useful signal corresponding with fish to be detected is compared, so as to obtain the fresh of fish to be detected
Degree value, finally shows the corresponding LED for characterizing fish freshness to be detected on display lamp.
The invention has the beneficial effects as follows：This fish freshness optical detection apparatus, using optical detecting method to Fish
Keypoint part at product three, i.e. fish body, flake, the fish gill carry out the detection of freshness, so as to obtain fish products freshness
Information.This structure of the detecting device is simple, workable, real-time detection fish products freshness.This detection means may be used also
It is integrated in the handheld devices such as mobile phone, it is convenient and practical.
【Description of the drawings】
Fig. 1 is the fish freshness optical detection apparatus structural representation of the present invention.
Fig. 2 is the signal processing flow figure of the present invention.
