Research On Path Planning AGV System Based On Wireless Network

With the quantity of AGV in logistics system being increasing and the environment of the factory being more and more complicated, the AGV system control and path planning is becoming particularly important. Therefore, path planning and obstacle avoidance are the important issues of this paper. Aiming at the objective requirements we designed the latent trail-type AGV, mainly for the AGV vehicle modular design and the development of its control system. Software system is divided into upper server system and slave computer system, and we mainly studied the AGV automatic control and transportation management system. The main content of this paper is as follows:First of all, this paper designed the overall of AGV system, and introduced the function of the AGV system. Then the paper designed the system’s structure and the car body of AGV. Finally, the paper analyzed the function of each subsystem, and selected the corresponding hardware and simply introduced working process of the system. Secondly, this paper studied the path planning of the single AGV, and established the electronic map according to the environmental information model. On this basis, analyzed the characteristic of single AGV path programming algorithm such as Dijkstra algorithm and A* algorithm. And with the demand of system stability and real-time, we chose the A* algorithm to solve the shortest path of AGV. Moreover, this paper programmed for the multiple AGV, and established the scheduling strategy. Studied the three common conflict situation Of AGV, compared the solution strategy with the characteristic of each algorithm according to their response to conflict thereby selected multiple AGV path programming based on a directed graph; and traffic rules based on the priority method of combining multiple AGV path programming.Finally, this paper introduced the software in detail and debugged the experimental prototype, Results showed that of basic it can essentially meet the functions requirements of the designed system, thereby lay a solid foundation for further study.
