Research On The AGV Based On Radio Frequency Identification And Gyroscopes Guiding

Automated Guided Vehicle is an integrated use of mechanical design, principle of automatic control, communication and information processing, and computer technology. It is a logistics transport vehicle equipped with automatic guiding and safety protection device, and can move along the fixed path. AGV has gained the development from emergence to the present, and has played a more and more important role in the modern logistics with the characteristic of high intelligence, high flexibility and high security. It quickly adapted to plant all kinds of complicated work environment and must will be incalculable applications in all various fields.Although AGV has developed rapidly, but the domestic study of it starts late and all kinds of core technology research progress has been slow. Because the high price and high requirements of using and maintenance of AGV, many high-end products need to import. And it is not gained popularity in the small and medium-sized enterprises. This article designed a low cost, populist AGV based on consulting a large number of literature and studying the existing AGV guide way. It innovative uses a way of guidance by radio frequency identification and gyroscope combination. This kind of guide way is simple structure and easy to implement. And it facilitate in the small and medium-sized enterprise popularization.This article formulated the overall scheme design of AGV following the principle of modular design on the basis of comprehensive analysis of the composition of AGV. According to the actual factory, comprehensive design for mechanical parts of the AGV is processed. It adopts four-wheel distributed structure. Two-wheel differential driving in the middle and casters guiding in the before and after can achieve straight, turn right, and spin around. By this way we can fundamentally solve the problem of the traditional AGV that turning radius is too large. According to control system requirements, we will do the AGV hardware unitized apart. We design independent modular units, and then need to finish complete assembly of the machine by the way of the building blocks. According to the AGV complete action, we use C language to write the control program of the AGV automatic control; with Visual Basic development platform to the software design of AGV, we can write PC control interface to realize the implementation of AGV path planning and task order and complete the scheduling of manual mode and automatic mode. According to the actual use of AGV, we design prototype to debug work. First, we plan the experiment site and working environment of the AGV. Second, we do separately verification for reading card speed and accuracy of the radio frequency identification module. Finally, the experiments are respectively performed in manual mode and automatic mode for AGV. Through analyzing the experimental data and tuning the parameters of associated performance, it can completely meet the requirements of design index.The article design the AGV based on the model of radio frequency identification and gyroscope guiding, and it used radio frequency identification as guidance and positioning. It solved the problem of magnetic guidance path is not easy to change and laser guidance is expensive in guidance with gyroscope. And it solved the problem of traditional guidance is low positioning accuracy. It truly realized low cost and populist, and can completely meet the requirements of small and medium-sized enterprises for AGV.
