摘　　要：针对卫星导航信号波形在不同硬件平台上的可移植性问题,在系统中引入Modem硬件抽象层(MHAL)后,实现了不同计算单元上组件间管理的统一性和通信的标准化.为了便于测试MHAL的标准符合性[1],防止不同研制单位研制出互相不兼容的软件通信体系结构(SCA)通信设备,现以某卫星导航接收机为例说明具体硬件平台的MHAL测试方法,设计了一组测试用例集.通过采用公共对象请求代理体系结构(CORBA)中间件TAO(The ACE ORB)和软件功能动态配置法,该测试用例集可屏蔽被测设备之间的差异,提高测试用例的通用性、兼容性、测试效率.用户只需在PC端一键操作即可完成自动化测试.结果表明:该测试用例集可以验证MHAL实现数据传输的能力、满足SCA标准的符合性程度和用户需求.Aiming at the portability of satellite navigation signal waveform on different hardware platforms,after introducing the Hardware Abstraction Layer into the system,the unification of management and communication standardization between components in different computing units are realized.In order to test the conformity of modem hardware abstraction layer(MHAL)and prevent different research units from developing incompatible software communications architect(SCA)communication equipment,a Satellite navigation receiver is taken as an example.MHAL test method based on specific hardware platform is explained,and a set of test cases is designed.By using CORBA(Common Object Request Broker Architecture)middleware Tao and software function dynamic configuration method,the test case set can shield the differences between the tested devices,improve the universality,compatibility and test efficiency of test cases.And users can complete the automatic test with one key operation on the PC.The results show that the test suite can fully verify the ability of hardware abstraction layer to realize data transmission and meet the conformity of SCA,so as to meet the needs of users.
