摘要
通过对数传接口数据的研究,提出了应用数传接口进行不同格式串行数据传输的设计。通过对不同种类数据的并串转换得到串行数据,将其进行不同的组合得到数传接口的多种格式数据,并基于FPGA进行了模块化设计。通过对其进行功能仿真、接口测试,以及对成像系统的图像数据的计算和分析,验证了该设计的正确性,并将其应用于某遥感相机的数传部分。该设计实现了数传接口的多格式数据传输,减少了数传接口的连接电缆和接口芯片的数量,有效地提高了数传接口的数据率,提高了数据传输应用的灵活性,对遥感相机的轻、小型化设计起到了重要的作用。
By the research of the data in the data transmission interface,this paper presents the design which implements different format serial data transmission through the data transmission interface. According to the different kinds of data which converted parallel to serial obtains the serial data. It was combinated differently that obtains the multiple format data in the data transmission interface. And the modularization design on FPGA was achieved. By function simulation, interface test and calculation as well as analysis of the image data in the imaging system, the multiple format data transmission design was verified and has been applied in a remote sensor＇s data transmission unit. The design implements the multiple format data transmission in the data transmission interface, reduces the amount of the interface chips and connected cables of data transmission interface, dffectively improves the data rate of the data transmission, improves the flexibility of the data transmission application, and it is important to make the remote sensor＇s design getting smaller and lighter.
