Embodiment 1

[0061] Build the spectrum acquisition part. A fiber optic spectrometer is used with a wavelength range of 815-1075nm and 1240 wavelength variables. C# language is used to develop spectrum acquisition software to realize spectrum acquisition. Collect the dark current, turn on the light source, and use the Teflon white board as the reference spectrum.

[0062] The original silkworm chrysalis of the silkworm Jingsong A variety were taken, 96 females and 100 males, and the spectrum was collected once a day until moths turned into moths. Belt rotation speed 5cm / s. A fiber optic spectrometer (MAYA type, Oceanoptics, USA) was used with a wavelength range of 815-1075 nm and 1240 wavelength variables. Set the spectrometer integration time to 15ms, and the number of spectral scans to 6,

[0063] On the basis of OminiDriver 2.12, use C# language to develop spectrum acquisition software to realize spectrum acquisition. Collect dark current, turn on the light source, and use the polyt...

Embodiment 2

[0065] The original silkworm chrysalis of several silkworm varieties were collected, including one local variety (Dazao), three original varieties used in production (Jingsong A, Su, Hu) and two hybrid original species (Ye B*Jingsong A, Su*zhen), 100 of each variety, half male and half male.

[0066] Spectral wavelength range 813-1075nm, 1250 wavelength variables. C# language is used to develop spectrum acquisition software to realize spectrum acquisition.

[0067] Collect the dark current, turn on the light source, and use the polytetrafluoroethylene white board as the reference spectrum. Belt rotation speed 20cm / s. A fiber optic spectrometer (MAYA type, Oceanoptics, USA) was used with a wavelength range of 813-1075nm and 1250 wavelength variables. Set the integration time of the spectrometer to 8ms, the number of spectral scans to 3, and collect the spectrum once a day until moths turn into moths. The resulting spectrum is 5962, such as Figure 6 shown.

Embodiment 3

[0069] In Example 2, female pupae are set as 2, and male pupae are set as 1. The spectrum is preprocessed by standard normal variable transformation, and the transformed spectrum is as follows: Figure 7 shown.

[0070] The model is modeled by the PLS method, cross-validated by means of random blocks, and the factor number 6 when the RMSECV is the smallest is used to save the model. The cross-validation results of male and female silkworm chrysalis were respectively fitted with normal distribution, such as Figure 8 , Figure 9 shown.

[0071] According to the probability distribution curve, the value M90 ​​of 90% probability distribution of male silkworm chrysalis is 1.445, and the value F10 of 10% probability distribution of female silkworm chrysalis is 1.620. If the calculation result is less than 1.445, it is judged as male, if it is greater than 1.620, it is judged as female, and if it is in the middle, it cannot be judged.

[0072] Load the preprocessing method, reg...

Abstract

The invention discloses a rapid male and female silkworm chrysalis sorting device comprising a sample feeding unit, a detection unit and a sorting unit which are connected in sequence. The sample feeding unit comprises a feeding belt and a vibration disc which are connected in sequence. The detection unit comprises a detection belt, a light source, an optical fiber probe, light switches, a spectrograph, a computer and a PLC unit, wherein the detection belt is connected with the vibration disc, and the light source, the optical fiber probe, the light switches, the spectrograph, the computer andthe PLC unit are arranged above the detection belt. The sorting unit blows silkworm chrysalises into a designated box when the silkworm chrysalises reach the designated positions according to the male and female results of the silkworm chrysalises obtained by the detection unit. By means of the rapid male and female silkworm chrysalis sorting device, the male and female silkworm chrysalises can be rapidly recognized, the manpower cost is greatly saved, and meanwhile the predicament that labor is in shortage is changed.

Description

technical field [0001] The present application relates to a device for automatic identification and sorting based on near-infrared spectrum analysis, in particular to a device and method for identifying male and female silkworm chrysalis by using short-wave near-infrared spectrum, for automatic sorting of male and female silkworm chrysalis. Background technique [0002] my country is the country of origin and dissemination of sericulture in the world, and it is also the largest producer and exporter of cocoon silk. The sericulture industry includes multiple links such as silkworm breeding, mulberry planting and sericulture. [0003] The vigorous development of the sericulture industry is inseparable from the stability and sustainable development of the sericulture industry. At present, the silkworm eggs used in my country’s sericulture production are hybrids of the first generation, which are obtained through mating between parents of strains with different biological and e...
