摘要
相较于双片式车载单元和复合通行卡,单片式车载单元在外观形态、性能、数据安全、交易时间、交易成功率等诸多方面均有明显改善和提升。为进一步验证其功能及性能,保证工程应用的可实施性,依据《电子收费单片式车载单元(OBU)技术要求》中原语结构及通信协议的相关规定,使用Visual Studio软件开发工具基于SM4算法完成了上位机测试用例及测试功能的设计,借助微波信号收发设备完成了不同测试用例数据的传输及交互。使用该协议测试及功能验证系统分别从单原语测试、多原语测试、交易测试等方面进行了较为完善的协议符合性测试。最后在相同测试环境下,分别对单片式车载单元与双片式车载单元交易时间进行对比,进一步验证了单片式车载单元的优势。结果表明:通过对单片式车载单元进行的较为系统的测试及功能验证,证明了单片式车载单元技术路线的可行性以及性能的优越性,为其在高速公路电子不停车收费系统中的应用与推广提供技术保障。
Compared with the dual-chip on-board unit and the compound pass card,the single-chip on-board unit has significant improvement and enhancement in many aspects such as appearance,performance,data security,transaction time and transaction success rate.In order to further verify its function and performance,ensure the implementability of engineering application,basis on the relevant provisions of primitive structure and communication protocol in The Electronic Toll Collection Single-chip On-board Unit(OBU)Technical Requirements,the test functions and test cases of upper computer are designed by using Visual Studio software development tool and SM4 algorithm.The data transmission and interaction of different test cases are completed with the help of microwave signal receiving and transmitting equipment.The relatively complete protocol conformance test is conducted from the aspects of single primitive test,multi primitive test,transaction test respectively by using the protocol test and function verification system.Finally,under the same test environment,the transaction time of single-chip on-board unit and dual-chip on-board unit is compared,which further verified the advantages of single-chip on-board unit.The result shows that through systematic testing and function verification on single-chip on-board unit,the feasibility of the technical route and the superiority of performance of single-chip on-board unit are proved,which provides technical guarantee for its application and promotion in the ETC system of expressway.
