Secondly, after the analysis of platform function and the platform network construction, the author studies deeply into the software design of interface server in the platform based on the main technique of mid-ware, including three functional subsystem of platform 最后,作者通过对各子系统的流程分析探讨了医疗信息共享平台的功能实现与应用。以上这些工作为本项目的全面实现奠定了扎实的基础。
Vehicle navigation system can be divided into four functional subsystems : digital map database management subsystem, vehicle positioning subsystem, route planning subsystem, and route guidance subsystem, as well as wireless communications subsystem . the functions which each subsystem should be realized as well as the key technologies to ensure the realization of these functions are proposed 将车辆导航系统划分为路网数据库管理、车辆定位、路线优化、路线引导四大功能子系统以及无线通信子系统,提出了各个子系统应实现的功能,以及实现其功能需要采用的关键技术。
