Open Controller Architecture Research

In this paper, open controller is studied systematically, the research progress of open controller is analyzed at home and abroad, and many design ideas in lots of systems with opening characteristics are integrated. From the point of architecture, the paper gives the overall composition and the level of division of the open controller, and describes the open controller's opening characteristics layer-by-layer.From the point that existing open controllers focus on the opening characteristics in the application layer. This article focuses on the mechanisms that the opening characteristics of open controllers are implemented in hardware layer and system level. Analysis the hardware layer of the response strategy of the open controller in the hardware module access/ system removal, and support the opening characteristics in hardware layer through dynamically loaded driver technology of the system level.Finally, we designed a model system with open controller, fulfilling the hardware design, Linux system transplantation and the application control of the new access stepper motor module. The paper tells how to choose the specific open controller module in order to adapt to specific application requirements in the process of constructing the actual open controller.
