本文設計了一種基于DSP 和CAN 通信的分布式電源系統監控平臺。本系統充分利用
了DSP 高速、實時、外設集成度高、擴展性強等特點和CAN 總線通信的高安全性和抗干擾性等優點。并充分考慮到系統產品化的特點，使其具有兩種監控模式和模塊化的可拆卸結構。文章首先從硬件設計方而對該系統進行了詳細的介紹，對系統中采用的重要的功能電路作了分析和說明，然后再給出了一些重要的功能軟件設計方法。

Abstract: Based on the origin and request of the system, a supervising system based on DSP
and CAN bus is designed. The character of DSP such as high speed, real time, multiple
integration peripherals, good expansibility and advantages of CAN communication such as high reliability, good resisting disturbance performance are fully applied in the system. Meanwhile, considering the system is designed as a product, two supervising mode for selection and modularization structure are designed. At first, the hardware design is discussed in detail and some important circmts are introduced too. Then the software design methods are presented.
