A method and device for compensating pantograph-catenary contact force of a pneumatic pantograph

ActiveCN121448173BImprove reliabilityDetection in advanceProportional controlContact force
The application discloses a kind of pneumatic-tyre pantograph pantograph contact force compensation control method and device, the device includes: front position detection module, control module, drive module and pressure feedback module;Front position detection module includes front position contactor;Front position contactor is set to the front side of pantograph;The contact force between front position contactor and catenary is same with the contact force between pantograph and catenary;Control module is used to obtain bow net contact force;Control module calculates the target pressure value required in air bag according to bow net contact force;Control module is used to obtain the actual pressure value in air bag;Control module is also used to output proportional control signal to drive module according to target pressure value and actual pressure value;Drive module is used to control the opening of the electric control proportional valve of air bag, so that the pressure value in air bag tends to target pressure value.The technical scheme provided by the application is to realize accurate monitoring and compensation control to bow net contact force.

An optimization method and system for timing chart subgraph matching

PendingCN122346567ABranch jumps are accurateReduce the effective solution spaceAlgorithmGraph match
The present application relates to a kind of optimization method and system of timing diagram subgraph matching.The method includes: time block is carried out to original timing diagram, and the edge with same end point is aggregated and compressed in each time block to generate intra-block multi-edge object, to build block index in turn;Query graph with time constraint is received, with the edge in query graph as matching unit to execute search, and maintain current legal time window;In candidate generation stage, according to current to be matched data vertex pair and current legal time window, construct cache key, and carry out exploration in hotspot cache;If hotspot cache is not hit, then use current legal time window to locate target time block, and execute intersection operation in target time block to generate candidate multi-edge list;When current to be matched data vertex pair meets preset hotspot condition, the candidate multi-edge list is written into hotspot cache;Continue to execute search based on the candidate multi-edge list of hit or generated candidate multi-edge list, until outputting model matching result.

Method for manufacturing optical film, optical film, polarizing plate, and liquid crystal display device

ActiveCN117047953BSmall delay valuereduce tensile stressPyranoseLiquid-crystal display
This invention relates to a method for manufacturing an optical film, an optical film, a polarizer, and a liquid crystal display device. The objective is to provide a method for manufacturing a wide-width optical film with low retardation values ​​in both the in-plane and thickness directions, and to suppress display unevenness caused by environmental variations in the display device, using a plant-derived resin. The method for manufacturing the optical film of this invention is characterized by comprising: a step of forming a strip film from a cellulose ester resin containing a total acetyl substitution degree of 2.30 to 2.60 and a sugar ester having a furanose or pyranose structure; and a step of stretching said strip film, wherein the retardation value R... o The range is 0–10 nm, R t The process of stretching the long strip film, with a wavelength of -10 to 10 nm, includes the following steps: a first step to obtain a first stretched film; and a second step to further stretch the first stretched film to obtain a second stretched film, wherein the stretching temperature of the second step is in the range of 190 to 220°C.
