组成作战系统的各设备所需数据种类繁多,数据访问各自为政、效率低、耦合紧密。为此,提出一种基于通信中间件的数据访问机制,设计该机制的体系结构,基于订阅/发布模式实现快速、无连接的数据访问,采用规则转换自动产生SQL语句,从而达到数据访问的最大松耦合,同时阐述机制的数据访问流程,并在某作战仿真系统中验证该机制的有效性。 The equipment needed to make up the operational system needs a wide range of data, data access and fragmentation, low efficiency and tight coupling. Therefore, this paper proposes a data access mechanism based on communication middleware, designs the architecture of the mechanism, implements fast and connectionless data access based on subscription / publish mode, and automatically generates SQL statements by rule conversion, so as to achieve the maximum data access Loosely coupled, at the same time elaborated the data access mechanism of the mechanism and verified the effectiveness of the mechanism in a combat simulation system.
