| With the progress of intelligent technology and the proposal of Chinese intelligent manufacturing 2025 and other concepts,traditional small and medium-sized manufacturing enterprises are facing great pressure of industrial upgrading.The general characteristics of such factories are obvious: weak capital,relatively crowded workshop environment,and a large proportion of material distribution cost in the total cost.Autonomous Guided Vehicle(AGV),as an effective means of parts transportation in factory daily production and storage system,has a wide range of application value and application prospects in various actual production backgrounds.Combined with the development status of AGV products in the existing market,this paper studies and designs a material distribution and handling AGV system.Taking small and medium-sized electronic processing enterprises as the background,this paper studies and analyzes the structural design and improvement of handling AGV,path optimization in the factory and control system design.The main work of this paper is as follows:Firstly,analyze the operation process of handling AGV in the actual factory,design the three-dimensional model of handling AGV in combination with the research background requirements,select the models of electronic components related to each functional module according to its functional requirements,then use ANSYS and ADAMS software to carry out static and kinematic simulation analysis on the three-dimensional model of handling AGV,and improve the frame structure in the three-dimensional model in combination with the stress and deformation simulation results,To avoid excessive local stress and overall deformation.Secondly,the path planning problem is studied in the case of factory stations and obstacles.It is determined that the global path planning category to be solved in this paper,and a fusion ant colony a * algorithm is proposed.In order to prevent the ant colony algorithm from falling into local optimization too early when solving the optimal sequence of stations,and at the same time,the shortcomings and shortcomings of the optimization algorithm,a new pheromone diffusion method is proposed to make the algorithm more accurate.The algorithm is brought into the simulation test in MATLAB simulation software,which proves that the improved fusion algorithm proposed in this paper can be better applied to the route planning of AGV transportation compared with the algorithm before the improvement.Finally,in order to facilitate the real-time monitoring of the current situation of the handling AGV system,the upper computer interface is designed with visual studio,the hardware of the lower computer is programmed with Arduino ide software,and the WIFI communication module is used to connect the upper computer and the lower computer,so as to realize the transmission of information and instructions.Experiments show that the handling AGV system studied in this paper can complete the required parts transportation,path planning and remote control functions. |
