Research On Control Technology Of AGVS Based On Multi Information

The AGV vision navigation and monitoring of AGVS scheduling technology are mainly studied in this paper. AGV navigation the present is not flexible and the number of the overall monitoring and scheduling technology is not much. In this paper an AGV system combined with the visual navigation, RFID positioning technology, remote monitoring is proposed.Firstly AGV vision navigation strategy is acted as the breakthrough point. Guide-line image is processed through image filtering smoothing, adaptive segmentation, and the distortion correction. Three different kinds of extraction method of guide-line deviation information are proposed. Then the angle, distance deviation parameters are acted as input and AGV wheel speed difference is acted as the output of designed fuzzy controller. Combined with Fuzzy Toolbox and Simulink, movement of differential AGV in any closed path is simulated. And a realization method of fuzzy control in VC is put forward. The AGVS monitoring and Orientation are achieved by software on a remote server. Video transmission module based on TCP/IP is completed. And in scheduling problem shortest path planning method is given based on the normalized model A*algorithm. Through the combination programming of VC++and OpenCV, the electronic map generated, imported, and the shortest path computation are completed.Finally, through debugging of the experimental prototype, the function is basically can satisfy requirements of the system. And it is a solid foundation for further study.
