Abstract


Electricity energy resources is not only necessary for people's daily life , but also plays an important role in national economic production . To be reasonable , adequate utilization of electrical energy , we must be timely grasp of the electricity supply situation and customer information . Power load management system came into being . The power load management terminal is the basic constituent units of the power load management system . Through the monitoring and management of electrical equipment , you can avoid the situation of power shortage in peak hours to reduce the strain on the grid , at the same time changing the load curve to improve the power grid health played an important role . Seriously study the existing power load management terminal technology and enterprise application requirements based on the design of a new power load management terminal based on the ADSP-BF531 DSP chip . In this paper, the design of this terminal a detailed introduction . First, highlight the measures to improve the performance of terminal AC sampling , including the of AC sampling circuit and AC sampling algorithm optimized design , and optimization of the sampling results were compared verify . Then, the terminal software and hardware design . In terms of hardware design , the modular design concept . First introduced hardware design of the overall program , and then carried out a detailed analysis of the various functional modules , such as CPU modules , data acquisition modules , communication modules , the man-machine interface module , power module . Software design , the use of modular structured programming methods . First introduced software development environment VisualDSP then introduces the overall scheme of the software design and programming of various functional modules . Terminal software and hardware design , fully consider the scalability and robustness of its function . Finally , the overall performance of the terminal test , the test results show that the performance of the terminal . The power load management terminal is the inevitable trend of the power system of information technology and automation . As energy issues increasingly tense , increasingly sophisticated terminal performance , I believe that the terminal will be more widely used .
