Research And Implementation Of Conformance Testing For Broadband Micro-power Wireless Communication Protocol

With the development of the Ubiquitous Power Internet of Things(UP-Io T),in order to achieve more efficient collection of electricity information,State Grid Corporation of China began to research the Broadband Micro-Power(BMP)wireless communication technology in the power information acquisition system.In order to develop a commercial BMP protocol stack and promote the industrialization of BMP wireless communication system,protocol conformance testing must be carried out on BMP communication devices to ensure the interconnection between BMP devices produced by various manufacturers.Therefore,this thesis studies the conformance testing of the BMP protocol.The main work of this thesis is to design and implement conformance testing case set and protocol conformance testing system of BMP protocol.First of all,through the in-depth analysis and research on the BMP protocol and the existing protocol conformance testing case set design methodology,and aiming at the disadvantage of low coverage of the latter,a Hybrid Finite State Machine(HFSM)testing case design methodology is proposed to improve the BMP testing item coverage.Secondly,requirements analysis and architecture design were carried out for the BMP protocol conformance testing system,and the development of the BMP testing system was completed based on Testing and Test Control Notation Version 3(TTCN-3)and Qt.The testing system can be automatically compatible with three testing modes for IUT,including Quick Emulator(QEMU)mode,Virtual RF Board(V-RFB)mode and Real RF Board(R-RFB)mode,which improves test efficiency and reduces test costs.In addition,the implementation of the transceiver module in the testing system improves the editing efficiency of the test script.Finally,the correctness of all functional modules of the BMP protocol conformance testing system was verified,and the protocol conformance testing was carried out on the implemented BMP communication equipment.After repeated modification and optimization of the code,the pass rate of test case finally reaches 100%.In this thesis,the implementation of the BMP protocol conformance testing case set and the implementation of the testing system provides a means of conformance testing for the research of the BMP protocol stack,promoting the commercialization ofthe BMP power information acquisition system,and facilitating the faster completion of the State Grid BMP wireless communication system project.
