Luminous flux control method of high definition vehicle snapshot system

The invention provides a luminous flux control method of a high definition vehicle snapshot system, belonging to the image processing field. The control method comprises the following steps: initializing the parameters of a camera, setting an initial photometric range and a photometric luminance reference value table; obtaining the current shutter speed value, gain value, reference datum value and current photometric interval of the camera; determining the photometric range of an acquired image; calculating photometric luminance value in the designated area of the photometric range; calculating the luminous flux control parameter; sending a control command, waiting in the designated photometric interval, and performing the next adjustment process. The method automatically adjusts the shutter and gain of the acquisition equipment and adjusts the light complement equipment according to the photometric result of a special area so that the pictures shot at any moment have proper exposure luminance, the problem that the exposure effects of the plate number and portraits in a vehicle on the traditional image are not consistent is solved; and the control method can be realized in the embedded system, thus the combination control of multiple devices becomes easy.

Microemulsified fuel oil and preparation thereof

The invention relates to micro-emulsification fuel oil and a method for preparing the micro-emulsification fuel oil by using garbage oil. The method comprises the following steps: using waste oil or oil foot as a main raw material, synthesizing a high-quality composite emulsifying agent by the raw material through three steps of aminolysis reaction, and thinning the raw material to 0.1 to 2 mu m by a high shear homogenizer to prepare the micro-emulsification fuel oil of A type, B type and C type respectively. The micro-emulsification fuel oil comprises the components in weight percentage: 76 to 84 percent of diesel oil, 8 to 12 percent of the composite emulsifying agent, and 8 to 12 percent of water. Except water content, other indexes of product quality of the micro-emulsification fuel oil accord with the diesel oil of international standard. The fuel oil has favorable ignition performance and no side effect for an engine, and can be stored for more than half a year. The method is suitable for oil for power of equipment such as various vehicles, ships, boilers, and the like, has cut-down function for tail gas discharge and effect reaching 30 to 50 percent, and has the characteristics of high heating value and low discharge. The micro-emulsification fuel oil is used for reducing fuel cost greatly at the same time of saving energy; and the developed micro-emulsification technique can meet the requirement of large-scale industrialized production.

Method for improving banana fruit wine appearance quality stability through membrane filtration

The invention discloses a method for improving banana fruit wine appearance quality stability through membrane filtration, which has the technical scheme that bananas are peeled, color protecting liquid is added for enzymolysis, fermentation liquid is regulated, the alcohol fermentation is carried out, the wine slag is separated, a ceramic membrane is used for filtration, and wine is bottled and stored. The method has the advantages that the quality of the banana fruit wine is improved, the appearance is clear and transparent, the transmission rate of the wine liquid reaches higher than 95 percent, simultaneously, the loss of the ethanol content and the mineral substance content in the wine liquid is reduced, the number of microbes in the fruit wine is reduced, the biological stability isimproved, the membrane separation has the characteristics of high separation efficiency, lower energy consumption, simple operation and the like, substances of thallus cells, macromolecular protein and the like can be effectively stopped, and the degerming rate reaches higher than 50 percent. Compared with the traditional high-temperature sterilization and chemical clarification method, the method has the advantages that the adverse influence on the flavor and nutrient components of the wine after the high-temperature sterilization can be avoided, in addition, the addition and reside problemsof external chemical substances can be avoided, and good application prospects are realized.
