Abstract

The utility model discloses wind egg detection equipment for before hatching, which belongs to the technical field of egg detection equipment manufacturing. In the utility model, a wind egg identification embedded system is constructed and comprises hardware like an ARM S3C2410 embedded system development board, a complementary metal-oxide-semiconductor transistor (CMOS) image sensor OV7620, a light-emitting diode (LED) and a buzzer. Wind egg identification software is constructed by using a C language and an assembly language in a Linux environment provided by the ARM S3C2410. The software mainly comprises a hatching egg acquisition module, an image edge detection module, a characteristic parameter extraction module and a three-layer back propagation (BP) neural network; the achieved main function is to identify wind eggs and fertile eggs by using the neural network according to the characteristic parameters (roundness, complexity, elongation, sphericity, ellipticity and coefficient of variation) of an acquired image. The output of the neural network is 10 or 01, and the output is used as driving level, and the LED makes display through an amplifying circuit to make the buzzer give out a sound. By using the equipment, the wind eggs can be conveniently and rapidly detected. The wind egg detection equipment provided in the utility model can completely meet the demand of getting rid of the wind eggs before hatching and is a high-efficiency practical wind egg identification system.

Description

On incubate before the wind egg screening washer

Technical field

The utility model belongs to the preceding checkout equipment of hatching of breeding eggs.

Background technology

The hatching process of planting egg approximately needs 21 days, and is higher to the ambient temperature and humidity conditional request, is a process consuming time, as to consume energy.According to middle and later periods eighties statistics, 59.7 hundred million eggs were hatched approximately in the U.S. in 1988, and clear egg accounts for 8%～9% of total incubated egg, and every hatching need spend 3 cents, and therefore the economic loss that causes is considerable.About 300,000,000 of incubation was gone in China Jiangsu Province in 1988, and clear egg calculates by 8%～9%, and only Jiangsu one province is with a toll of millions of units.This means all has unfertilized kind of a large amount of eggs not hatch every year, and its economic loss that causes is quite big.Be implemented in and detect before kind of egg goes into to incubate that wind egg can not only be saved time effectively, space, labour and the energy, improve hatching efficient, can also guarantee the health and the quality of production of environment of hatching, and wind egg can be used for food, huge economic and social benefit is arranged.In actual applications, reject wind egg, this technology still adopts hand-held simple and easy candler to carry out the head photograph at the 5th day that hatches, this method workload is big, speed slow, the human factor influence is bigger, and behind the fresh-laid egg hatching 72h, quality is reduced to below the second class, should not be processed into egg products, waste a large amount of table eggs, consume useless energy.Therefore develop and detect the wind egg system automatically before a cover can be incubated on kind of egg,, improve detection accuracy and production efficiency, ensure the producer's interests, have crucial meaning reducing artificial labour intensity according to egg.Mainly be to have adopted the computer vision method to detect kind of an egg at present both at home and abroad.Former study shows that Dynamic Non-Destruction Measurement can be applied in really effectively and incubates in the later detection on kind of the egg, but also exist some problems, as study mainly concentrate on the hatching early stage wind egg detection, and the detection to wind egg yet there are no relevant report both at home and abroad before the hatching, and research all be under laboratory level, to finish, also have a segment distance from practical application.This paper study a kind of be fit to needs both at home and abroad based on Machine Vision Detection wind egg method, and can form that a cover is portable, commercialization wind egg screening instrument, to satisfy at present hatching market to the requirement of rejecting wind egg before incubating on kind of the egg.
