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。
In order to acquire the target image clearly, the airborne TDICCD camera system needs the on-board navigation equipment to provide the attitude and movement information of the aircraft in real time. The bus adaptation technology is the key to implement the information sharing and integration between the camera and the airborne navigation equipment. Developed bus adapter mainly by the data receiving module, data conversion module, signal conditioning and frequency adjustment module, data processing and data transmission module and other components. Can receive ARINC5 6 1 bus, ARINC42 9 bus, AR INC40 7 bus and receive send RS 42 2 bus data. The system solves the bus frequency adaptive adjustment, fault isolation and other key technologies. Test proved that the system is stable, accurate data reception, high reliability.
