碩士 === 國立中央大學 === 資訊工程研究所 === 99 === This paper designs the embedded system architecture of the GRAFCET virtual machine, and implements it with ARM Cortex-M3 microcontroller core. Base on this software and hardware, we propose a fast prototyping development platform for smart controller. The fast prototyping development platform for smart controller means it is a combination of DES and CTS hybrid controller. The controller uses GRAFCET graphic language to describe its high level behavior and we can easily combine CTS controller into the system through the DES/CTS formal interface. In order to provide the developer an intuitive and convenient development environment, we designed the GRAFCET editor. The smart controllers behavior which described by GRAFCET can be translated to the coding table that virtual machine can execute right away. The advantage of this platform is that the developers don’t need to use the hardware-dependent translator and programming language. Instead, they can use the graphic interfaced high-level behavior description and automatic generating the target prototyping system of the smart controller. It can achieve fast-integration and verification. In the end of the paper, we verify and demo our smart controller with the example of robot controlling and temperature controlling. It shows that the platform really has the advantage of fast-rapid prototyping system development.
