Abstract
The intelligent distribution terminal is modern distribution management system to achieve an important guarantee for the economic development of society growing demand for electricity, making the original distribution terminal can no longer meet the requirements, and because of the rapid development of various technologies and The emergence of new technologies, distribution management to promote the development of a new terminal also. Distribution of this subject in the research and analysis on the basis of management development, and then made reference to the basis of previous research programs, combined puter technology, communication technology, information technology, management and system control technology, the intelligent distribution terminal on the study design. the design of intelligent distribution terminal,which is based on the ARM processor and Embedded Real-Time Operating System(RTOS),is presented and overall design of the hardware and software is carried out.
Smart device development in the distribution, the use of multi-dimensional solidification design (ie: communication protocol curing, curing function points, logic curing), to achieve system power load, stealing, power loss aspects of prehensive data collection, analysis, and system fail
