The Computerized Control Of WY1.5 Hydraulic Excavator

Integration of mechanical engineering and mechanical engineeringand robot technology is the inevitable trend of development,Hydraulicexcavator of the robots to improve not only the construction, chemical,irrigation, mining and other excavation site efficiency,improve theworking environment, reduce the labor intensity of operators and mayreplace people in dangerous places operations to protect the safety ofoperators. Although the current domestic and foreign intelligenceexcavator people in a number of areas of research, also made someprogress, since excavation robot working environment is scurvine andchangeable, the task is too great uncertainty, few of research resultscan really into actual production. for Jilin University will pilotremote-controlled excavator as a "211" projects "engineering equipmentdisciplinary group" one of the main elements of the building. The aimof experiment station is tracking construction projects robotics in theworld advanced level, development of autonomous robots for mechanicalengineering research and high-level talent to provide experimental tool.This study is the transformation of experimental station remoteexcavator--Based on the mobile vehicle controls hydraulic excavationJidianye ratio control.First settled of papers is hydraulic excavator experiments stationnormal start-up failures. experiments station is based on the WY1.5 typehydraulic excavator of Shaoguan, it is normal start when november 2001excavator arrived at the school. , the maintenance and replacement ofthe relevant owners have failed to identify the cause of the malfunctionof components. Transformation began in March 2005, carefulinvestigation and experiments confirm excavator normal start because :this type excavator without cryogenic start experiments, , unable tomeet its start-up circuit in a state of cryogenic start, is a designerror. Based on the results of the study, proposed solutions, excludedfrom the normal start of the engine failure.The analysis of the hydraulic system constitutes WY1.5 hydraulicexcavator, Access contemporary and mainstream excavator hydraulicsystem design basis ,made the programme of electrical hydraulic system.The programme does not alter the original hydraulic system with the useof functional, hydraulic systems for electrical achieved by theoriginal hydraulic system with the same functions, Two systems parallelconnection but can not use principle. Electrical hydraulic systemvalves ratio achieved not only through electromagnetic devices at thesame time work for more control and the median return to oil, convergenceof double-pumps electromagnetic not directly proportional valvesachieved through ancillary functions electromagnetic Huanxiangfaaccomplished.In the design of hydraulic valves boards and manufacturing process,in the absence of any form of reference data. Author through visits,ask some experienced hydraulic engineers , crafts designers and workerschef, After revising completed electrical excavator hydraulic valvesboard design. According to the design and manufacturing process.Hydraulic valves made of the general board design steps, Methods andattention to the matter, workers in the design of hydraulic valvesboards have on value.Electrical hydraulic excavator control of the selection of theGerman Inter Control mobile vehicle controls production companies.The PWM controller through the expansion of the mouth, all work towardsthe installation of excavator ,start circuit, discharge valve and thecontrol tower,and have a feedback interface, complete control of theirin-depth study as excavator wisdom experimental platform capabilities.Upon completion of the authors of papers published an article duringone chapter, Participated in the living area --Jilin EPA Sewage projectto tackle difficult problems. Author preliminary study migrationvehicles controller programming language "PROSYS₁131" andinternational electrician standard IEC-61131. Established thehydraulic pressure excavator automatic control program, After debugsand tests confirms, this procedure stable reliable,It Has realized theexcavator computer control. And accumulated the precious experience forthe successor excavator laboratory bench remote control and theintelligent control.
