The invention discloses a hydrocracking product quality self-control method, device and memory, wherein the method includes the steps of: acquiring monitoring data of the hydrocracking system; unifying the collection period of various monitoring data according to the preset data standard of the monitoring data and collection time points; determine the parameter items that are related to product quality and can be adjusted in the working condition data as automatic control parameter items; construct modeling data; conduct modeling data based on preset target variables and preset independent variables Model training to generate a product quality prediction model; take the key parameter items determined from real-time monitoring data as input, and obtain the prediction result of the preset product of the hydrocracking system through the product quality prediction model; when the prediction result exceeds the preset range value , according to the prediction model to generate an adjustment scheme for automatic control parameter items. The invention can keep the working condition of the hydrocracking unit in a reasonable running state, and then can effectively reduce the unqualified product quality.

The invention relates to the technical field of image processing, in particular to a diabetic retina image quality detection method based on an image analysis technology. The method comprises the following steps of: preprocessing the fundus image, performing morphological treatment, equalization treatment and filtering treatment on the fundus image during the pretreatment process, performing brightness detection, optic disc detection and definition detection after the pretreatment, and finally obtaining the fundus image to be diagnosed, and diagnosing diabetic retinopathy. The preprocessing operation in the method greatly improves the visibility of the retinal fundus image, It is more advantageous for doctors to diagnose and analyze the patients' condition, and the quality inspection operation can greatly reduce the occurrence of the unqualified fundus images taken at the census spots. The fundus images which pass the quality inspection can be used for the preliminary diagnosis of diabetic retinopathy.

The invention relates to a tail door suspension chain transport device which comprises a supporting rod and a tail door fixing device. The tail door fixing device is mounted on the supporting rod. Thesupporting rod is located in the middle of the tail door fixing device. A pulley is arranged at the top of the supporting rod. The tail door fixing device comprises locking devices, fixed clamp grooves, a limiting device used for limiting left-and-right movement of a tail door and a support, and the locking devices, the limiting device and the fixed clamp grooves are all mounted on the support. The limiting device comprises limiting blocks. Each locking device comprises at least one tongue piece and an adjusting mechanism used for adjusting the up-and-down position of the tongue piece. A ballhead pin clamp groove is formed in each tongue piece. The tail door fixing device is mounted on the supporting rod through a bearing and a limiting pin. According to the tail door suspension chain transport device, the transport efficiency can be improved, and the transport cost can be reduced; and flexible transport is achieved, and the situation that products are unqualified due to the reasonssuch as colliding generated in the transport process is reduced.

The invention discloses an aluminum and aluminum alloy inert-gas shielded welding process suitable for plates of 8-12 mm thickness. The aluminum and aluminum alloy inert-gas shielded welding process comprises the steps of adopting flame cutting to cut a welding product so as to obtain 40-degree double-faced one-sided groove with welding joint ratio of 1:2 and ensuring that no grooves exist in the cutting face; sticking a protective film to the plate product, adopting acetone and a rotary file to remove oil stains, aluminum chippings and oxidation films at the positions to be welded, on the end face and edge of the aluminum alloy plate within 20 mm range and expose metal luster before welding, wherein no air bubbles exist in the protective film, the protective film is not bonded in a 50-100 mm range within the welding position; adopting inert-gas shielded welding; selecting corresponding aluminum alloy welding wires to perform welding according to material models of aluminum and aluminum alloy plates during welding, and continuing to perform welding without stop in the middle process. By means of the aluminum and aluminum alloy inert-gas shielded welding process, the process of the welding process can be effectively controlled, the whole process and product quality stability are ensured, disqualification phenomena are decreased, and the aluminum and aluminum alloy inert-gas shielded welding process is suitable for aluminum and aluminum alloy welding of the plates of 8-12 mm thickness.

The invention relates to a PROTOS unit tipping paper single offset roller gluing system which comprises a fixing mounting plate and a glue feeding device. A positioning mechanism used for fixing the glue feeding device, a paper raising roller mechanism, a sensor and a positioning pulley used for controlling the trend of tipping paper are arranged on the fixing mounting plate; the glue feeding device is clamped on the positioning mechanism; and the paper raising roller mechanism is arranged above the flue feeding opening of the glue feeding device. Compared with the prior art, the gluing system has the advantages that loss of water in glue solution is reduced, the phenomenon that the glue solution is polluted is avoided, and attrition rate of a glue roller is reduced, so that the service life of the glue roller is greatly increased, the consumption of parts is reduced, and the like.

The invention provides an IC card packaging device and method. The IC card packaging device includes a packaging platform, a hot pressing device, a cold pressing device, a negative pressure device, a transmission device and a power unit, and the hot pressing device and the cold pressing device are along the IC The card transmission direction is set in sequence, the hot pressing device includes a hot pressing head, and a heating device is arranged in the hot pressing head; the cold pressing device includes a cold pressing head, and a card slot matching the size of the IC card is provided on the packaging platform , the bottom surface of the card slot is provided with adsorption pores, and the negative pressure device communicates with the adsorption pores.
