Research and design of embedded data acquisition and monitoring system based on PowerPC and CAN Bus

The embedded system takes the application as a center, which can adapt the strict demands of application system well to the function, reliability, cost, size and power consumption etc. Freescale Corporation´s PowerPC series chip has the powerful communication capacity, the system stability as well as disturbance rejection ability. The CAN bus obtains the universal applications in the industrial control field as one of most widespread fieldbus. Take Freescale Corporation PowerQUICC II technology´s high-end dual-core chip MPC8248 processor as the core, an embedded data acquisition and the monitoring system platform based on PowerPC and CAN bus has been designed and developed in this paper, which can solve the high demand data acquisition and monitor, network and communication effectively for the applications of electrical power system. At the same time, the data can be transferred by Ethernet communication interface to the remote monitoring systems such as DAS or DCS for further analysis, processing and storage after being analyzed and processed by the platform. It is of great application significance.
