摘要
采用高性能微控制器和FPGA(field-programmable gate array)组合硬件平台,进行以太网数字影像数据的接收、满足IRIG106(inter range instrumentation group106)遥测标准的PCM(pulse code modulation)编程、IRIG-B时间码转换与配置、高速数据调度管理和多类型信号电平输出的硬件电路设计和制作。通过实验室和用户现场环境测试,验证了硬件设计的完整性和可靠性。
The ethernet digital image telemetry encoder has the problems of various function,complicated structure,required high real-time.We use the combination hardware platforms of high-performance microcontroller and FPGA（Field-Programmable Gate Array）to receive ethernet digital image data.The PCM（Pulse Code Modulation） frame format can be programmable and meet the standard of telemetry IRIG106（Inter Range Instrumentation Group 106）,configuring and transforming IRIG-B time code.The dispatch and management are of high-speed and efficiency.The designing and making of hardware circuit about Multi-level signal output validated the accuracy and reliability of hardware circuit by the environment of laboratory and user site test.
