Foreign fiber cleaner was widely used in the field of cotton processing industry for its good cleaning efficiency. However, with the improvement of cotton processing level, how to improve the foreign fiber's cleaning efficiency and reduce the fiber's damage had become a growing concern, which was taken as the research object in the paper. This paper designed four-factor quadratic orthogonal rotation test. The four factors were the capacity of foreign fiber cleaner, the regain of seed cotton, the winding roller speed and the wind speed. The cleaning efficiency of foreign fiber and the damage of fiber length were objective functions. For the multi-factor test, orthogonal test design was an effective method of scientific experiments where part of the ones can reflect the comprehensive experiments. Through these factors quadratic orthogonal rotation test, the multi-objective optimal control model of foreign fiber cleaner was established. The results revealed that the remarkable factors which influenced the cleaning efficiency of linear foreign fiber were the winding roller speed, the regain of seed cotton and the wind speed, while the capacity of foreign fiber cleaner was not remarkable. The regain of seed cotton and winding roller speed had significantly interactive effect for the cleaning efficiency of linear foreign fiber. Higher winding roller speed, wind speed and lower regain of seed cotton would improve the cleaning efficiency. The effects on the cleaning efficiency of linear foreign fiber were in order of winding roller speed > wind speed > regain of seed cotton > capacity of foreign fiber cleaner. The effects on the cleaning efficiency of flake foreign fiber were in order of wind speed > winding roller speed > regain of seed cotton > capacity of foreign fiber cleaner. All of the factors were the remarkable factors. The effects on the damage of fiber length were in order of winding roller speed > regain of seed cotton > wind speed > capacity of foreign fiber cleaner. The remarkable factors which influenced the damage of fiber length were the winding roller speed, the regain of seed cotton and the wind speed. The model in this paper has been applied in the multi-objective optimization control of foreign fiber cleaner. Users could adjust the parameters of foreign fiber cleaning machine according to their demand in the actual production. In the conditions of this study, Compared with a fixed value control method, the cleaning efficiency of linear foreign fiber by using multi-objective adaptive control method was increased on average by about 9.4%, the cleaning efficiency of flake foreign fiber was increased on average by about 3.3%, and the damage of fiber length was reduced on average by about 0.051%. Cleaning effect was satisfactory. [ABSTRACT FROM AUTHOR]

Lotus seed has very high nutritional and medicinal value, which consists of lotus shell, lotus kernel and lotus core. Because of the bitter taste, the lotus cores need to be removed before eating. The existing equipment for removing core can remove the lotus core fast by operating the coring bit. Before drilling, the lotus kernel has to be centered in the centering working position. The centering device generally consists of two rotating rollers. Under the action of gravity and friction force, the lotus kernel can be centered in the rotating process. However, the position of the coring bit is fixed in the centering working position, and therefore the drilling deviation occurs due to the diameter variation of lotus kernels, and the lotus cores cannot be removed effectively, which lowers the quality of lotus kernels directly. To solve the above problems, the classification process is applied widely. However, it is ineffective owing to the inaccuracy of the classification process and the high requirement for staff and equipment. In order to avoid this situation, the shape parameters of lotus kernels are firstly measured and analyzed in this paper. The results show that the maximum cross section of the lotus kernel is almost round with a mean roundness deviation of 0.46 mm and the diameter ranges from 9 to 16 mm; the average chordwise curvature radius is 7.764 mm, and the average longitudinal curvature radius is 5.177 mm, therefore, the shape of a lotus kernel can approximate to an ellipsoid. Moreover, the centering deviation of the double roller rolling centering method presents a maximum value of 6.654 mm. Aiming at solving the problem of drilling deviation in the automated coring of lotus seeds, this paper proposes a self-adaptive centering method for lotus seeds based on a slider-crank mechanism and a parallel crank mechanism. By utilizing this method, the position of the coring bit can be automatically adjusted according to the lotus kernel size. A mathematical model of self-adaptive centering is established by the complex number vector method. Once the parameters of the linkages are selected, the centering deviation value is determined. For the self-adaptive centering mechanism, the optimization of the linkage parameters is complicated and difficult to meet the demand through traditional optimization methods. Therefore, in order to make the centering deviation minimum, by utilizing the stochastic optimization algorithm of Cuckoo Search, this paper optimizes the linkage parameters in MATLAB. The initial parameters are as follows: the nest number is 25, the probability of detection is 0.25, and the maximum iteration number is 4×105. The optimized parameters of connecting rod are 88.51, 135.72, 0.12828, and 125.35 mm respectively, and the coaxial deviation between the coring bit axis and lotus kernel axis is lower than 0.05mm. Based on the above study, a self-adaptive machine for removing core of lotus seed was developed and a coring experiment with 400 samples of lotus seeds was carried out. The experimental parameters were as follows: the working cycle was 1.5 s, the roller's rotating speed was 238 r/min, the pressure of the pressing wheel was 25 N, the coring bit diameter was 2.5 mm and the drill speed was 2800 r/min. By measuring the circle run-out value at the maximum cross section of the lotus kernel, the drilling accuracy of lotus seeds were calculated. The results show that the drilling accuracy of a self-adaptive machine for removing core of lotus seed is 91.25%, much higher than that of the existing equipment, which is 60%-70%; moreover, this machine can handle different sizes of lotus kernels. The experimental results verify the effectiveness and practicability of this self-adaptive centering method. [ABSTRACT FROM AUTHOR]

Chrysanthemum is one of the top 10 traditional famous flowers in China, which has significant importance and great ornamental value and medicinal value. The chrysanthemum flowers are characterized by a large number of varieties and a wide range of petal shapes, which pose big challenges to their intelligent identification and efficient management. Currently, the identification and management of chrysanthemum mainly relies on the traditional manual way, and as a result, the efficiency is quite low. At the contemporary era, deep learning as a powerful technique in artificial intelligence field is becoming a prevalent way of identification and classification on text, image, video, and so on. Based on the end-to-end convolutional neural network deep neural network directly acting on the original chrysanthemum image dataset, this paper aims at obtaining the characteristic information of chrysanthemums through the multi-layer neural network. By this means, the problem of extracting the features manually is avoided, and then optimization target function is applied to achieve a better image recognition accuracy. Based on this, the system of chrysanthemum flower pattern intelligent recognition and breed classification is researched and implemented. In view of the subtle differences among the flower patterns of chrysanthemums, on the one hand, in order to preserve as much information as possible for the data, tensor is employed to represent the image data; on the other hand, the pairwise confusion loss function based on pair similarity is used to distinguish pattern differences and similarities. By this means, the objective function of distinguishing the different flower patterns is realized on the fine grain size. The system not only can identify the chrysanthemum pattern, but also can give the probability value of the top 3 results. In addition to this, the variety information covered by the flower pattern is also provided. The operation of the system can be divided into 2 stages: the off-line training and the online classification. Off-line models can be hosted in the cloud environment such as Amazon AWS for the easy usage on the mobile platform. Moreover, the model can be replanted and updated with little hindrance. In order to train the network model, we collected a large amount of data of real chrysanthemum image, and manually marked the relevant pattern and category information of chrysanthemum. Based on the datasets, we conducted extensive experiments with our system and made comparisons with 3 existing systems, and experimental results show that: The identification accuracy of the system has been significantly improved compared with the existing systems for chrysanthemum flower pattern. Beyond that, the system can provide more detailed chrysanthemum species information at the same time. The average recognition rate can reach about 0.95, and even surpass the rate of 0.98 for some chrysanthemum patterns. The system provides a powerful means for the automatic management of chrysanthemum and fills the gaps in chrysanthemum pattern recognition and classification. In this paper, the research on the intelligent identification and effective management of chrysanthemum flower pattern has great significance in theory and practice. [ABSTRACT FROM AUTHOR]
