The invention relates to a detection device for lychee stem borers and a using method, belonging to the technical field of lychee stem borers detection, comprising a camera assembly, a detection assembly and a recording terminal device. A guide rod, the second guide rod is connected to a second circular ring, a plurality of detection holes are arranged on the second circular ring, and at least one indicator light is arranged on the outer side of each detection hole, and the indicator light is provided with at least two indication states, The indication state includes a state with lychee pedicle borers and a state without lychee pedicle borers; the present invention passes automatic detection through the whole process, and can perform all-round detection on lychees, solves the phenomenon that the occluded view area cannot be detected, and improves the detection data. Accuracy rate, but also conducive to the detection of personnel statistics. The present invention is small in size, can be easily carried to the site for sampling and all-round detection of lychees, and is beneficial to instructing farmers to spray pesticides.

The invention discloses an LCD screen advertisement device assembled on a shopping trolley. The device comprises a shell with an LCD screen; both ends of the shell can be fixedly connected with push rods of a supermarket shopping trolley; the interior of the shell is provided with a speaker and a play control circuit structure which comprises a CPU control module, a data storage module, a data transmission module and a power supply module; and the CPU control module is connected with the LCD screen, used for processing and playing advertisements and respectively connected with the data storagemodule for storing advertisement data information, the data transmission module for providing a communication transmission interface and the power supply module for providing a power supply for the device. The advertisement device utilizes a propaganda platform of video image playing, can repeatedly play and periodically replace advertisement information while fully utilizing the mobility and thecustomer universality of shopping trolleys, and can attract supermarket consumers during selecting goods to pay attention to consumer information to the maximum extend, thereby widening the contact area with the consumers and the influence of the advertisements.

The invention discloses an image processing method based on a matrix variable variational autoencoder, which can solve the problem of image vectorization processing destroying the spatial structure, and further facilitates image reconstruction, denoising and completion. Different from the traditional VAE, this method uses the inherent representation of the image-2D matrix to describe the input of the model, hidden layer features, latent variable distribution characteristic parameters, etc., and derives the target of the new model by using the definition and related properties of the matrix Gaussian distribution The explicit expression of the function, and then use the stochastic gradient descent algorithm to solve the model parameters. In this model, since the modeling process involved in the present invention is oriented to matrix variables, it can better model the spatial structure and statistical information of image data, thereby improving the quality of image reconstruction, better removing noise and image Completion.

The invention relates to an oocyst incubation method for whelks, and belongs to the technical field of aquaculture larval rearing. The method is as follows: removing the oocysts of the whelks to an incubation basket; placing the incubation basket (3) in an incubation pool (5) for incubating, wherein the incubation basket is made of the polyethylene plastic, 50 cm long, 30 cm wide, and 25 cm high, the interior is covered by 60 meshes of bolting-silk net, the bottom is leveled, two edges of the upper end of the incubation basket are bound with rigid foam (7) so that the basket is floated on the water surface; placing an inflating device (4) on the bottom of the incubation basket for inflating slowly, wherein the upper part of the incubation basket is provided with a flowing device (1) made of polyvinyl chloride (PVC) pipes, the water is flowed from a flowing hole (2), and the water discharge is 7-8 L / minute; and incubating by using the flowing water. The method is capable of achieving the artificial incubation of whelks, and providing the feasible approach for large-scale production of whelks, and has the advantages of simple and convenient technology, high incubation rate, and low production cost.
