一种无线总线桥相关应用软件

摘要

针对系统引入无线总线桥后的应用软件具体需求,提出一种无线总线桥相关应用软件设计方案.结合时间序列模型和事件触发模型,设计底层ARM处理器固件程序;运用套接字技术,实现WLAN接口背景下符合VXI-11标准的仪器自动发现机制;通过开发 VISA 管理库函数,建立配套的系统仪器管理工具.经过验证:该设计能实现多种机载设备总线接口、GPIB 仪器管理接口和 WLAN 接口的实时可靠操作,有效简化了系统操作流程,实现了在无线总线桥硬件机制下的仪器远控.%According to the specific needs of application software after the introduction of WLAN-bus-bridge in system, put forwards the related software design scheme of WLAN-bus-bridge. Combined with the time series model and event trigger model, the underlying ARM processor firmware was designed. In the background of WLAN interface, an instrument auto-discovery mechanism in line with the VXI-11 standard using socket technology was achieved. A series of system instrument management tools were established by developing VISA management library functions. The verification shows that the design can realize e real-time and reliable operation of a variety of airborne equipment bus interface, management interface and WLAN interface in GPIB instruments. The design can effectively simplify the system operation process, and realize the remote control in WLAN-bus-bridge hardware mechanism.
