The Research On The Parameter Collection And Intelligence Examining System Of Flash Welding On Anchor Chain

Along with the development of the shipping of world, the safe demand of the shipping urged the creation of the anchor chain.Chain developing from the first plant rope, casting anchor chain to the flash welding anchor now, have already had a history of several hundreds years .Currently the foreign anchor chain factory produces about 260,000 tons a year, which mainly have four namely Korean anchor chain factory in Korean, nation anchor chain factory in Japanese, Vicinay in Spanish and Ramnas in Sweden.The anchor chain's development of China is late and the part of high-quality anchor chains main of local market dependent on import.Flash welding is very important in anchor chain produce , so it is already the of the utmost urgency to the technical research of the supervision of the welding of the anchor chain. The process of flash welding is many parameters comprehensive influence, opposite and bad process of the electricity environment, the welding's process does not continue and the process establishment precision of model is very difficult, even basically can't the establishment mathematics model, control the theories for the thus complicated system classic and modern control theories are all incapable is dint of, therefore, in the supervision system of the flash welding research, the actual welding experience data seems to be very important.Currently, each big work in world controls the factory's product of DCS and so on are gradually maturing.But these product for some and small scaled device or the device of the special use to say, one hand the price is too expensive, and is multi-function not to use up, on the other hand can satisfy some special requests.Therefore, many situation, we still need the independence to develop small scaled turn, low cost, have the calculator monitor system of the special function.According to the misty classification theories, at flash welding's different stage, the adoption welding experience data conduct and actions standard,establish a motion scope.( threshold value)Whether the data that exploitation collect judges the flashlight in the scope or not is to the welding quantity of the welding , and come out a the spot manifestation that passes the composing of LED of the welding circumstance hold and the window way interface manifestation of Windows is.Owing to the complexity of the flashlight process, this text draws up to adopt two kinds of collect the frequency to carry on data's collect.A kind of collect the way is to collect to weld the parameter of valid value( low frequency), carry on welding the quantity in the process judgment with the threshold value, and fitting report to the police signal for .A kind of collect the way is a moment that collects to weld the parameter to be worth( high frequency), use the data of the precision to carry on the theories analysis.Two kinds of methods cut over through an interface.Passing a great deal of experiment, this kind of collects the system to have the cost cheap, the operation is vivid, the parameter establish vivid, the physical volume is small, easy to take, monitor credibility in time etc. advantage, attain the purpose of supervision.
