【摘要】 NMEA0183协议解析模块是导航系统中重要的软件模块,该模块的健壮性和高效性直接关系到整个导航系统的性能.经过深入分析NMEA0183协议的结构和编译技术的特点,提出了一种利用编译技术解析NMEA0183协议的方法.整个解析过程分为四个阶段,分别对应于编译技术中的词法分析、语法分析、语义分析和代码生成.目前该方法已经应用到GPS导航产品中,实测表明解析模块稳定可靠,达到产品级要求.更多还原

【Abstract】 The module,parsing NMEA0183 protocol,is a critical part in the guiding system software.The robusticity and efficiency of the module affect the performance of the guiding system directly.The deep analysis of the NMEA0183 protocol structure and the compilation technology characteristic leads to the method for parsing NMEA0183 protocol using the compilation technology.The whole process is composed of four phases:lexical analysis,syntax analysis,semantic analysis and code generation.Now,the method has been used in the GPS guiding system product.The corresponding module works stably in practice,and meets the request of the product level.更多还原
