摘　　要：结合嵌入式实时操作系统VxWorks下信息处理系统的实际应用,以其中的多线程串口解析处理GPS消息为例,研究了在VxWorks下配置BSP参数,设置串口及多线程环境,并通过串口对GPS中GPGGA消息进行实时采集、解析并处理的关键技术,给出了信息处理系统的总体架构、串口多线程设计和GPGGA解析算法。Based on the practical application of information processing system on the real-time embedded operating system Vx Works, as an example of parsing and processing GPS messages with multithread serial port, the technology of the BSP configuration under Vx Works, and how to set the serial port and multithread environment are studied in this paper. Then, the key technologies of GPGGA messages are collected, resolved and processed through serial port. Finally the overall architecture of the information processing system, the design of multithread serial port and GPGGA parsing algorithms are proposed.
