Centralized multi-user cabinet energy meter is a new type of energy meter , it measurement of the number of households is generally more than 100 , especially for apartment buildings , dormitories , integrated office and residential area with the use of a number of areas . Than ordinary power management devices , with smart IC card management mode , LCD character display system against short circuit , overload prevention , anti-tampering , and many other functions , in addition to the advantages of small size, easy installation and maintenance . In addition , the authors still vicious load - recognition technology to conduct a preliminary study , proposed several novel vicious load recognition technology , because of the time , and no further in-depth research , the sole purpose is to play a valuable role. The main work is centralized multi-user design the hardware and software of the power meter . The main contents are as follows : First , on the basis of a brief analysis of the development status and composition of principle of the energy meter proposed centralized multi-user energy meter overall cabinet design , fully taken into account in the design of the program , system scalability and cost-effective . The design uses a time division multiplexing method of measurement , and greatly reduces the cost of the system , simplify the hardware structure of the system design . Cabinet table function should have a detailed drawing system schematics and PCB system board diagram, design PCB hardware board , selected and buy chips and electronic components and welding . On the basis of pre- made ??hardware and software design and programming and debugging , the various functions . Combined with the the cabinet power meter , vicious load identification technology . Anti-jamming system design , software and hardware to enhance system reliability . The system 's hardware and software debugging work has been basically completed , the actual operation shows that : the system is convenient and practical , high measurement accuracy .
