At present the measure means of electricity quantity is depended on drivers to copy the data by interring the consumers,not only the man-power and material resources are wasted,inevitably make errors by mistake,but also brings inconvenience to daily life of consumers.Along with the development of city modernization,it is necessary current to construct intelligent zone,the primary man copying is not equal to the present work,and the new electricity quantity measurement means develops,and along with the development of communication and computer technology,it makes intelligent zone possible Resent years our country was popularizing out-door measure technology,make true that copy power conveniently, not disturbed consumers,a great deal of man copying work gradually transitions to numeric transmission..this article focuses on how to realize the intelligent zone of the advanced management in electricity.In the artiele,it was proposed to the practical and feasible solution to the zone-automated managemen in the quantity of eleetricity measurement system.This artiele what to do primarily is:choosing the appropriate meter;Designing the model of measuring system in zone:writing the instruction program to the hardware and accomplishing the appropriate program to run general data.The means of measuring was choosed which is the automatic meter reading system.It should have the functions:the data aequisition function,the set up parameters,the control to system,the advanced charge system and the protection funetion.The system makes use of the MCU which is low cost and high performance as the principal part to design hardware,it contains electric meter based on ADE7758, The enganced one based on ADE7758 which can measure reactive powers and visual power yet.,and the design of collection based on AT89S52 connects between electric meter and the concentration based on PIC16F84 using asynchronous serial communication technology based on RS-485 electric interface as communication means,satisfying the meter's communication with the collector and concentrator of communication with the host computer.The process of sending data frames is analyzed and communication protocol is made.At the same time,the article used SQL Server technology and Visual C++ program language to design the remote reading management software system. In addition,the article analyzes kinds of uncertainty and disturbance factor,takes series of effective measures to advance the reliability and anti-disturbance capability of the system in design process. |
