Vehicle Emissions Classification Management System Test System Design And Realization

Low carbon strategy has become a global transformation of the economic and social development of the consensus, Low carbon traffic has gradually become urban sustainable development trend. Based on RFID technology, it has the innovation in the environmental management and the domestic leading level in technology through the development and design of vehicle emissions classification management system, and construction of low carbon traffic area. The front-end equipment performance of vehicle emissions classification management system plays important role in the construction process. By developing the test system of vehicle emission classification management system, it may select the equipment that can meet performance requirements and lay a solid foundation for low carbon traffic area construction.The paper studies the working principle of vehicle emission classification management system and the characteristics of RFID system, and then analyses and descripes the test system of vehicle emission classification management system. Besides that, the paper expounds the function requirements and performance indexes. According to the function requirement and performance indexes, the author firstly simulates and designs electronic tags by HFSS simulation software. UHF reader can be designed through modular design, and it includes analog RF circuit, digital baseband processing circuit and power circuit. The author secondly designs and realizes the test system software by loading the dll,calling API functions and using MFC library in the Visual C++ 6.0 platform. The author finally debugges the system and discusses and researches the conflict algorithm and link coding issues.This thesis has achieved the design requirements and put forward a performance testing evaluation system based on the test system. What's more, it provides unified test standard for the other similar project and forms application standard of industry gradually.
