Design of train GPS information controller
Abstract ：This topic will be based on uV2 software and ARM experiment box. Using C51, ARM experiment box and uV2 software and the relevant knowledge, such as GPS integrated application of theoretical knowledge to design GPS train controller so that the design of train GPS information controller could be achieved. The first part of this article simply introduces the GPS positioning system, including its introduction, the structure, working principle and so on. The second part is to introduce the composition of the GPS train controller, working principle and so on. The third part is about the hardware design of the controller. In this part, each module circuit principle and circuit diagram has been analyzed and circuit diagram has been drawn. The fourth part is about the writing of the program and explain the it’s function which will finally achieve. Eventually get to the conclusion that GPS train controller can be designed and bring contribution for railway development.
