The Overall Scheme And Key Technology Research Of Logistics Transportation AGV

AGV is the key equipment for automated logistic transportation system andflexible production organization system, which plays an important role in automationlogistics storage system. This subject is originated in logistics training centerconstruction in Polytechnic School of Shenyang Ligong University, and basing on thepractical requirements to AGV in this paper, this paper mainly reserches the keytechnology of AGV with magnetic guiding method, comprehensively utilizes the motorcontrol method, designs the logistics AGV by magnetic technology and also reserchesthe key technology involved in this paper.Firstly, this paper introduces the application and development of AGV,Accordingto the requirements of the logistics practical traning project construction, givesoverview for the key technology of AGV, then proposes the performance requirementsof logistics transportation AGV. This paper also raises the overall scheme for thislogistics transportation AGV in view of the performance requirements and technologyrequirements for logistics transportation AGV, which includes the mechanical structuredesign, body structure and the layout, driving method, sensor and control system. Thislogistics transportation AGV takes the form of electronic differential driving and theswerve of it is flexible and reliable.Secondly, according to the AGV’s differential method, This paper selects thecaculation driving motor and designs the AGV’s hardware solution scheme and controlscheme which includes the controller, laser scanning in safety area, servo motor, servodriving, fast-charging nickel-cadmium battery, magnetic guiding selection andapplication. Basing on the study and analysis of differential swever, this paper proposesthe electronic differential methord again, estabilishes the AGV’s differential drivingmathematical model, analyzes the kinematic model of it and verifies the feasibility ofdifferential swever according to the AGV’s driving structure.Finally, this paper describes the direct current serve control method of logisticstransportation AGV, proposes the PID fuzzy control stategy of AGV, and which hasbeen studied. This paper also gives verification and simulation to the fuzzy controller by MATLAB software and analyisis for the simulation results.
