Abstract：This text introduce intelligence to be long-range to check meter system , check meter and charge and become intelligent essential conditions in the district automatically automatically, will influence and go to the district to develop. Adopt Lonworks technology applying to check meter in intelligence , the electrical home appliances are automaticallied control , such systems as district Ann defends, meet material life that the people increase day by day's needs.
Three forms (water , electricity , coal gas ) based on LonWorks technology of key research make a copy for the system long-rangly . It is because of technology of the computer , the communication technology of the network , automaticallies control and microelectric technique , gather user's scattered water , electricity , gas meter data in the district , is carried on centralized management by the computer of centre of the property, settle account in unison. This systematic group's network is flexible , opening is good , easy to expand .
Key words：ARM, fieldbus, LonWorks technology, energy-consuming meter
