Multi-module AMI Message Processor Research And Design

With the vigorous development of the power market,the continuous innovation of network communication technology and power electronic technology,the shortcomings of low resource utilization and low automation in traditional power networks have been gradually compensated by smart grids.Among them,the advanced metering system AMI is the core of smart grid data transmission,and the AMI platform is the core part of the advanced metering system.It is responsible for the statistics and processing of smart meters,concentrators,and user data in the entire grid.It is also the core of the smart grid.One of the key technologies,the AMI message processor is the core of the AMI platform,so the research and development of the AMI message processor plays a very important role in the development of the smart grid.First of all,this article introduces the corresponding platform support,code writing framework and their functional structure.Three basic structures under the AMI platform system structure are designed: AMI system architecture diagram and the composition structure and functions of its various parts,the logical architecture of the AMI message processor and the functions of the corresponding interfaces,the AMI message processor function modules and various functions The description of the module.Introduced the scalability of the platform architecture,including the scalability of software and physical architecture.Secondly,this article analyzes the requirements of the AMI message processor from two aspects.The first aspect is the system's requirements for the AMI message processor.From the AMI message processor reliability requirements,boundary and data exception requirements,and testability Three aspects are required to be introduced;the second aspect is the platform services required by the AMI message processor,and its function support interface is introduced.At the same time,the multi-module deployment mode of the AMI message processor is designed.In order to avoid the confusion of data transmission,the corresponding data upstream and downstream forwarding process is designed.For multi-module deployment,the possible events of the AMI message processor node are proposed,and the solution for memory data synchronization is given.Finally,design instructions for task forwarding,event alarms,and remote support upgrades under multiple modules are given.Finally,this chapter designs the interface scheme between the AMI software management platform and the AMI message processor,and presents the AMI software management platform and AMI from four aspects: data collection task management,database connection,meter parameter recall,and event alarms.Interface design between message processors.Then the corresponding interface functions of the AMI message processor are designed,such as parameter issuance,task issuance(periodic task,real-time task),data collection,and the code implementation is completed.Finally,the software function interface corresponding to the AMI message processor is realized.
