【Abstract】 By using of 32-bit digital signal processor (DSP), embedded Advanced RISC Machine (ARM) and 16-bit synchronous serial A/D converter, a full isolated distribution and utilization monitoring terminal is designed and implemented. In this design multiple anti-interference measures realized by hardware and software are adopted to improve the reliability of this device; the buffer technique based on hardware and software as well as the optimized query algorithm for historical data are applied to improve system efficiency. The General Packet Radio Service (GPRS) module is taken as communication means and the reliability of its application is further researched and practiced. For fixed-point DSP, the C language programming is adopted, thus both reliability and maintainability of the system are enhanced.更多还原
