Battery management system with balanced charge and discharge functions and control method thereof

The invention discloses a battery management system with balanced charge and discharge functions and a control method thereof, relating to a battery management system of a dynamic battery pack. The battery management system is structurally characterized in that a central processing unit (CPU) control unit is connected with a battery and relay set so as to detect the working condition of the battery and relay set; the CPU control unit and a balanced discharge module are successively connected with the battery and relay set so as to control the balanced discharge of the battery and the relay set; the CPU control unit, a balanced charge module and the battery and the relay set are successively connected so as to control the balanced charge of the battery and relay set; and a super-capacitor is connected with the balanced discharge module so as to store the discharge energy of the battery and relay set for supplying power for the battery management system. The battery management system can be widely applied to management of various battery packs such as a lead-acid battery, a lithium battery, a nickel-metal hydride battery and the like, supports the expansion of a lower computer, and can conveniently detect and monitor the conditions of multiple batteries.

Method and system for in-store shopper behavior analysis with multi-modal sensor fusion

The present invention provides a comprehensive method for automatically and unobtrusively analyzing the in-store behavior of people visiting a physical space using a multi-modal fusion based on multiple types of sensors. The types of sensors employed may include cameras for capturing a plurality of images and mobile signal sensors for capturing a plurality of Wi-Fi signals. The present invention integrates the plurality of input sensor measurements to reliably and persistently track the people's physical attributes and detect the people's interactions with retail elements. The physical and contextual attributes collected from the processed shopper tracks includes the motion dynamics changes triggered by an implicit and explicit interaction to a retail element, comprising the behavior information for the trip of the people. The present invention integrates point-of-sale transaction data with the shopper behavior by finding and associating the transaction data that corresponds to a shopper trajectory and fusing them to generate a complete an intermediate representation of a shopper trip data, called a TripVector. The shopper behavior analyses are carried out based on the extracted TripVector. The analyzed behavior information for the shopper trips yields exemplary behavior analysis comprising map generation as visualization of the behavior, quantitative shopper metric derivation in multiple scales (e.g., store-wide and category-level) including path-to-purchase shopper metrics (e.g., traffic distribution, shopping action distribution, buying action distribution, conversion funnel), category dynamics (e.g., dominant path, category correlation, category sequence). The present invention includes a set of derived methods for different sensor configurations.

Green biological active feed

The invention discloses a green biological active feed, which relates to the technical field of feeds. The green biological active feed is prepared from the following materials in part by weight: 40 to 80 parts of straw, 5 to 30 parts of corn four, 5 to 25 parts of cake dregs, 5 to 25 parts of wheat bran, 0.1 to 0.2 part of complex bacteria and 0.1 to 0.2 part of complex enzyme. During preparation, the straw is crushed and then is uniformly mixed with the corn flour, the cake dregs and the wheat bran; the complex bacteria and the complex enzyme are mixed into the mixture; water is added into the mixture to ensure that the water content reaches 45 to 50 percent, and the mixture is filled in a big tank, sealed and stored for later use; or the mixture is baked or dried by natural wind for storage and later use. The green biological active feed has the following advantages of: (1) improving the balance of intestinal flora, and improving the feed utilization rate; (2) promoting the growth of meat livestock and poultry, and shortening the breeding cycle; (3) strengthening the body conditions of laying hens, ducks and geese, and having a significant strengthening action on prolonging theegg-laying peak period; (4) strengthening the body condition of female domestic animals, and improving the yielding rate; (5) strengthening the body conditions of the livestock and poultry, enhancingthe disease prevention and disease resisting capacities, and reducing the sickness rate; and (6) purifying the culture environment, and improving the meat quality due to no public nuisances and no residues.

High-precision and constant temperature and humidity cabinet

The invention relates to a high-precision and constant temperature and humidity cabinet, which is used for storing special articles. The temperature and humidity in the cabinet can be controlled within designated scope automatically and constantly. In the invention, a cooling/heating semiconductor high-temperature stacking is used as a temperature control and dehumidification executive component, an ultrasonic wave humidifier is used as a humidification executive component, and an electric temperature/humidity sensor, a series of fans, keys, a display, a controller and the like are mounted, thereby realizing constant temperature and humidity. When temperature inside the cabinet is higher than preset target temperature, the temperature control semiconductor high-temperature stacking generates forward current to reduce the temperature inside the cabinet; when temperature inside the cabinet is lower than the preset target temperature, the temperature control semiconductor high-temperature stacking generates reverse current to raise the temperature inside the cabinet to the preset target temperature; when humidity inside the cabinet is higher than preset target humidity, the dehumidification semiconductor high-temperature stacking generates forward current to reduce the temperature of a condensation block in the cabinet to be below the dew point, so as to enable moisture in the cabinet to condensate and flow into a water tank to realize dehumidification effect; and when humidity inside the cabinet is lower than preset target humidity, an ultrasonic wave humidifier sprays water mist to raise the humidity in the cabinet to the preset target humidity.
