某型无人机机载任务管理计算机设计

The Design of Mission Management Computer for a Certain UAV

某型无人机系统具有多挂载能力,能同时挂载多种任务载荷。为了统一管理和综合使用多个任务载荷,通过分析机载任务设备接口的类型和通信需求,设计一种具有接入现有设备能力的任务管理计算机。该机采用成熟的插卡式集成设计方式,具备较好的使用灵活性和功能扩展能力。通过该任务管理计算机可实现对任务载荷设备的控制,对遥控、遥测、载机状态数据的管理,以及授时同步功能。任务管理计算机对任务载荷设备的综合管理,能够提高无人机任务载荷的集成能力,减少了任务载荷与载机平台之间的交联关系,使任务载荷系统更加独立,降低了任务载荷系统对飞行平台安全的影响。

A certain UAV can mount kinds of payloads at the same time. A kind of mission management computer（MMC） is introduced to manage and make full use of those payloads. By analyzing the interface types and communication requirements of the existing on-board mission equipment, a task management computer with the capability of accessing existing equipment is designed. The computer adopts mature plug-in integrated design mode, and is of better flexibility and function expandability. All the payloads are controlled by MMC. Teleme- try and telecontrol data message of the payloads is managed by MMC. The MMC provide synchronization timing service for external devices. Payload integration capabilities can be improved by designing the MMC, and achieve independence to run the task system and flight control system. Thus the safety of the UAV platform can be improved.
