Research On Multi-Meter Integration Technology Based On Electricity Acquisition System

“Multi-meter unification” project is the implementation of the national smart city development strategy,enhance the whole society intelligent service level.The State Grid focus on promoting the “multi-meter unification” project,to achieve water and electricity,warm,gas and other public utilities data integration of remote reading mode Using existing acquisition platform in power system,build a new energy service mode,fully support the construction of smart city,reduce duplication of hardware.Through research electricity acquisition system and communication technology,a system architecture,the typical collection of electricity technology,Analysis of the current problems about “multi-meter unification” Technology and Application,discusses the development prospects of “multi meter unification”,which has an important significance to build smart city.First of all,comparative analysis of the M-BUS,RS-485,micro-power wireless,wireless public network,power line carrier and other communication technologies adopted by the industry in multiple tables is used to select the optimal communication mode from the operating conditions.Secondly,a power collection system architecture was set up.In order to meet the principle of intensive design with multiple tables,the collection terminal,remote channel,and host of the power consumption information collection system were reused under the premise of complete integration of the acquisition terminal layer and above.Stations and explore the complexity of architecture in real applications.Then,three typical multi-sheet technology solutions were designed: upgrading wireless modules,replacing dual-mode modules,and adding communication interface converters.Based on the typical design plan,taking into account the relative location of the electric water and gas heat meters and the location of the water and gas heat meters installed on the spot,three situations of mixed residential areas,scattered users,concentrated residential areas,and scattered users are taken into consideration,and the future is considered high.The frequency data collection and application requirements have selected multiple tables for different technical applications.Next,Yingtan City was selected as the multi-meeting collection demonstrationsite.According to the actual situation of water meter installation in Yingtan area and the results of joint acquisition of the acquisition system technology,the NB-IoT narrow-band internet of things meter reading technology was innovatively promoted,and technical conditions,residents' feelings,construction period and various factors were steadily advanced in stages,relying on existing The use of electricity information collection system,constantly optimize the collection program,solve technical problems,continue to improve the collection success rate and stability.Finally,a business system platform was set up to explore the collaborative operation of various functions,achieving the synchronization of water,gas,electricity meter and public user files from the marketing system,ensuring the user information and metering information and marketing in the collection system.The system maintains a consistent goal.
