Study Of Floor-Standing Watt-Hour Meter And Malignant Load Identify

Multiuser Floor-standing Watt-hour Meter is a sort of new-style Watt-hour Meter.Because it can measure exceed one hundred doors,it is fit for apartment block, campus dormitory,all-around office building as well as residential area especially.Compare with common electric managing equipment,it has intelligentized IC card function,LCD Chinese characters display system and it can anti short circuit,anti overloading,guard against steal electricity and so on.It has many excellences,such as small body,accout for smaller area, and the appearance is beautiful,and it is very convenient for installation and maintenance.Otherwise,author make some research in the field of malignant load identify. The emphasis of the dissertation is placed on the design of hardware and software and the main contents listed as follows:firstly,on the basis of the analysis of Watt-hour Meter development,and its compositive theory, the whole design scheme of Multiuser Floor-standing Watt-hour Meter was presented.During my design,take the extension into full account.The application of TDM simplify the structure of the meter and reduce the cost.To the functions that Multiuser Floor-standing Watt-hour Meter should have,choose and purchase the CMOS chip and electronic elements needed in the design.Layout the PCB plot and finish the PCB board.On the basis of former work,debug the hardware and software.realize the functions expected.A large amount of work has been on the analyse of malignant load identify.The debug work of hardware and software has been completed on the whole.Practice has proved that the system is realiable and simple.
