The invention discloses a charging and discharging power distribution method and system for fast equalization of SOC of multiple energy storage modules, and the method comprises the steps: calculating the sum Esumt of the total target electric quantity of a system according to the load power PLoad, the remaining electric quantity Eir of each battery pack and the equalization time T, then distributing Esumt according to the proportion of the maximum available capacity Eimax of each battery pack, obtaining the target electric quantity Eit of each battery pack, and obtaining the maximum available capacity Eimax of each battery pack; finally determining the reference power of each battery pack; carrying out capacity over-limit judgment on the Esumt, determining whether an over-discharge problem occurs to a single energy storage module of the energy storage system or not, and if the corresponding problem exists, reducing the reference power of the energy storage module with the over-discharge problem by adopting a power distribution method under capacity over-limit; according to the invention, the SOC balance of the multi-energy storage module system can be realized under the condition of balancing the load power, and a good balance effect is achieved when the SOC difference value is small; when it is judged that the over-discharge problem exists, the normal operation time of the system can be prolonged, and the SOC balance degree of the system can be improved.

The invention discloses a special extruding and filtering device for biological product materials, which comprises an outer frame, a material containing disc and a transverse plate, the material containing disc is arranged outside the outer frame, the material containing disc is in sliding connection with one side of the outer frame, and the transverse plate is arranged at the bottom of the material containing disc; the stress plates are evenly installed on the inner wall of the material containing disc, the stress plates are elastic plates, and arc-shaped filter screens are installed on the stress plates; the invention discloses an extrusion plate and relates to the technical field of material extrusion and filtration equipment. The special extruding and filtering device for the biological product material achieves the purpose of improving the filtering efficiency, can avoid the problem that filtrate extruded from a biological material located at a relatively high position easily permeates into a material below to cause waste, improves the use safety degree, can conveniently observe the extruding and filtering force, and is convenient to use. Equipment damage caused by increase of extrusion force is avoided, the positions of the materials can be changed in the extrusion and filtration process, and it is guaranteed that the materials in different positions are extruded and filtered in a balanced mode.

The present application relates to the technical field of teaching management, and discloses a kind of artistic practice course's mixed teaching task collaborative allocation method and system, the method includes: the multi-source task sequence and teaching state data of target process are collected, and task chain is constructed based on execution constraint and dependency relationship. Available resources and role state are combined into state snapshot, according to the demand of first task, candidate role set is filtered, the role with minimum load is selected as allocation target and is set as load balancing anchor point, and cascaded successor task obtains collaborative allocation sequence. Continuously receive the attendance signal and completion signal of offline classroom and online platform, and are associated and bound according to timestamp and corresponding task node, to generate execution event track. According to the state transition mark in track, update node state, form collaborative allocation closed loop record;The present application can improve the efficiency of artistic practice course's mixed teaching task collaborative allocation.
