Study Of Related Technologies Used In Remote Control Excavator Based On Motion

Technology of remote control excavator based on motion is an effective remote controlstrategy for achieving remote control excavator. Compared with the traditional handle wirelessremote control excavator, the remote control excavator based on motion has many advantages,for example, simple equipment, a further remote control feature and a flexible operation and soon. However, due to the influence of arm movements and location of sensor installed, it can’tmeet the requirement of the excavator job very well. Many functions of the excavator arerestricted, particular for achieving movements of a plurality work devices of the excavator,which will reduce the working efficiency of the excavator to a certain extent, as a result, limitingit use in engineering practice. At present, against the control excavator based on motion,domestic and foreign scholars had put forward some solutions to enhance its engineeringapplication more practical, but there are still many deficiencies, because of this, the controlscheme rarely apply in the practical engineering applications.In this paper, after a comprehensive analysis of the current situation in remote controlexcavator research at home and abroad, against the shortcomings, to further improve its controlstrategies, make it more practical use in engineering application and certify it by doingexperiment studies. The purpose for studying the remote control system of excavator based onmotion is to provide a theoretical reference and application guidance, so that it can better meetthe practical engineering applications, the main contents and achievements of the dissertation areas following:1. Firstly, analysis the current situation and development trend on remote control excavatorresearch at home and abroad, to clarify the significance of this research.2. Based on the previous studies in remote control excavator using human arm and hand,proposing an improvement program against its shortcomings and having a feasibility analysis forthe improved scheme, demonstrating the feasibility of the improved scheme from the theoretical,at last propose a complete set of control scheme for remote control excavator based on motion.3. Giving the control scheme for composite motions control in a number of working devicesbased on motion, to improve the efficiency of the remote control excavator based on motion tosome extent. Then use fuzzy-PID control strategy to achieve the main synchronization controlfrom the end, to improve the control accuracy.4. Showing plans in building a physical laboratory bench for simulation, the main building plans including the rehabilitation plan for hydraulic excavator and the physical laboratory benchfor simulation, then build a physical simulation platform for the experimental verification of theremote control excavator based on motion.5. Having an experimental study for related technologies in remote control excavator Basedon the physical simulation platform, to test its control performance. Debugging and optimizingagainst the existing problems, so as to better meet the requirements of the excavator job.6. Concluding the experiment results and having a comprehensive evaluation for theexperimental results, making predicts and outlook in direction and development for furtherresearch.
