Design And Implementation Of Interoperability Test System For Broadband Micro-Power Wireless Communication Modules

As the Internet of Energy has become a new strategic direction of the State Grid,in order to increase the transmission bandwidth of electricity information,the State Grid has proposed broadband micro-power wireless communication technology applied to the electricity information collection system.In order to ensure the interoperability and interconnection between broadband micropower wireless communication modules developed by different manufacturers,based on the research of the interoperability testing technology,this thesis designs and implements the interoperability test system of broadband micropower wireless communication modules.The work completed in this thesis mainly includes the following aspects:1.The structure of broadband micro-power wireless network is researched and analyzed in this thesis,and the international general distributed interoperability test framework is introduced according to the distributed characteristics of its network.At the same time,the interoperability test principle,procedure and the application of TTCN-3 in interoperability testing are analyzed,which provide basis and method for the design and implementation of the test system.2.Based on the analysis of the interoperability test scenarios of broadband micro-power wireless communication modules,the test system is discussed from three aspects: user requirements,functional requirements and non-functional requirements.The overall architecture of the test system is designed,of which the detailed architecture design for the software and hardware platform are carried out respectively.Based on the analysis of the broadband micro-power interoperability test project,test case sets are generated,and the main functional modules of the test system are implemented,which includes TTCN-3 abstract test suite,test support module and test management software,as well as the realization of the control of the main equipment in the hardware platform of the test system.3.The integrity and reliability of the interoperability test system are verified from three aspects: verification of functional modules,verification of system functions,and verification of test cases.The quality of the broadband micropower wireless communication module directly affects the reliability of the power local communication network.The research in this thesis can effectively detect the function and performance of the broadband micropower wireless communication module.At the same time,it can also provide a solution for the State Grid Measurement Center to test the interoperability of the same type of products developed by other manufacturers and promote the application of broadband micro-power wireless communication protocol.
