摘　　要：对有时间精度要求的型号地面测试软件的开发进行了研究。提出了基于多媒体定时器技术的高精度定时器,以及基于DevExpress控件技术的通用数据呈现界面框架的实现方法,并应用在型号软件中。该方法满足了型号软件非实时操作系统运行环境下(20±5)ms的时间精度需求,通用界面框架降低了型号软件的体积,基于数据源绑定的模式,提升了数据加载和呈现速度。The development of ground test software with time accuracy requirements in certain models of launch vehicles is studied. An implementation method for the general data presentation of interface framework based on high definition timer in terms of the multi-media timer technology and DevExpress controls is proposed and used in ground test software. It is shown that the method can meet the time accuracy requirement of(20±2)ms in the non-real-time operating system,and the generic interface framework based on the data source binding technology reduces the software scale and improves the speeds of data loading and presentation.
