TDICCD相机总线适配器的设计

Design of bus adapter in aerial TDICCD camera

航空TDICCD相机系统为了清晰地获取目标图像 ,需要机载导航设备实时提供飞机的姿态和运动信息 ,总线适配技术是实施相机与机载导航设备信息共享与融合的关键。研制的总线适配器主要由数据接收模块、数据转换模块、信号调理和频率调整模块、数据处理以及数据发送模块等组成。可以接收ARINC5 6 1总线、ARINC42 9总线、AR INC40 7总线和接收发送RS 42 2总线数据。系统解决了总线频率的自适应调整、故障隔离等关键技术。试验证明 ,系统运行稳定 ,数据接收准确 ,可靠性高。

For capturing high resolution target images, the system of aerial TDICCD camera requires the posture and movement information of aircraft that were real-time provided by navigation system. The bus adaption technique is the key technique of realizing information share and fusion between camera and navigation system. The bus adapter that were made out consists of data reception module, data conversion module,signal adjustment module, frequency adjustment module, data processing and data transmission module etc.It can receive the data of ARINC561 bus, ARINC429 bus, ARINC407 bus and RS-422 bus. In designing process, the key technique that includes frequency self-adapting and failure isolation were worked-out. The system has accurate receiving data, high reliability and running steady in test flight.
