Asphalt Pavement Cold Recycling Machine Control System Design

With the national energy saving, take the introduction of sustainabledevelopment policies, road construction asphalt cold recycling technology has beenwidely used as a renewable technology cold recycling machine core constructionequipment, because of its complex structure, multi-function, automatic controlrequirements, has long been regarded as a bottleneck in the application of renewabletechnologies, particularly intelligent control to be improved. Thus there is a need forasphalt pavement cold recycling machine control system overall development anddesign.In this thesis, is pavement cold recycling machine automatic control system.Through the collection, comparison and analysis of the performance parameters andtechnical characteristics and other domestic cold recycling machine, describes thedevelopment of cold recycling machine at home and abroad, and gives a generaldefinition of cold recycling machine, the structure and control functions. By analyzingthe cold recycling machine construction process, proposed control system functionalrequirements and control system theory, based on functional requirements andprinciples of the overall scheme cold recycling machine control system design,hardware configuration, program design and application examples analysis.In cold recycling machine system design, complete engine control systemsolutions, walking control system solutions, steering control system solutions,renewable sprayed control system solutions, cooling fan control system solutions andauxiliary device control system solutions. In hardware design, gives the cold recyclingmachine fully digital network control system solutions based on CAN buscommunication technology, completed the hardware design of intelligent controllers,HMI and slope controller, and the controller of the pin assignment. In the softwaredesign, gives the main structure of cold recycling machine control system design iscompleted the walk to control program flow, spray control program flow, steeringcontrol program flow and communication display system program flow, and gives therelevant flow chart. In the application examples analysis, describes the various control functions ZBL2500type cold recycling machine construction industry through thetesting process of assessment of urban roads rehabilitation and reconstruction of ruralroads regeneration analysis to verify the feasibility of the control system.Performance test cold recycling machine control system showed that the controlunit cold recycling machine fully functional, easy to control, low failure rate, meet thedesign requirements, can be mass-produced. Currently, the cold recycling machinecontrol system has been applied in DingSheng TianGong Construction Machinery Co.,Ltd`s ZBL2500Cold recycling machine, and has been in volume production.
