摘要
介绍了一种无线抄表管理系统的设计方案,简要介绍了智能消息语言(Smart Message Language)技术,利用SML数据通信结构的特点设计数据帧格式,实现了数据通信格式统一;系统基于VC++6.0环境开发,采用Windows的Winsock开发通信模块并采用Access2003数据库和ODBC数据库访问技术实现数据处理功能;搭建由无线终端、PC机、无线接入点和电表组成的实验系统来验证系统的通信功能,电表接220V市电,管理软件显示电压在220V范围内小幅波动,与电表实际值相同,并且数据可以每两秒刷新一次;系统高效的实现从下位机抄收电表数据、数据实时显示,处理和保存的功能,并且可以对电表的读数进行统计管理,有效解决了传统抄表方式的安全性和效率性不高问题。
This dissertation introduces a method for the designing of wireless meter reading management system,briefly introducing Smart Message Language technology.SML data structure is used to design the format of data frame to unify the data structure for communication.This system is developed based on vc＋＋6.0 environment,using Winsock of Windows to develop the communication module to and using Access2003 database to realize the function of data storage and processing.A experiment system composed by a wireless terminal,PC,a wireless access point and a meter is constructed to test the communication performance.The voltage that the meter connected to fluctuates in a small scope around 220V and is the same as meter data and the meter data can be updated every two seconds This system achieves the function of reading meter data from lower-computer,data processing and storing,solving the problems of safety and efficiency of traditional meter reading ways.
