某型导弹飞控系统遥测信息接收装置设计

摘要

Principles of full period and all data receiving are adopted in the process of telemetry receiver design to meet test requirements of flight control system on an airborne missile. The design of digital telemetry receiving unit is based on the monolithic processor, which promotes the automatic signal processing capability of the system, whereas signal isolation technique is applied in analogue telemetry receiving unit, reducing the influence of the apparatus to the product. The test accuracy of the signal is guaranteed by high speed AfD acquisition circuit, all period of time data receiving is realized by big capacity FIFO, data analysis and failure distinction are improved easier and more precise by graphic spectrum analysis.%根据某型导弹飞控系统遥测信息的测试要求，该遥测信息接收装置设计采用全时段、全数据接收的原则。数字遥测信息接收单元以单片机为核心，提高了测试板对数据的自主处理能力；模拟遥测信息接收单元通过信号隔离，减少了设备对产品的影响，高速MD采集保证了信号测试精度；大容量FIFO实现了数据全时段接收，图谱分析使数据分析及故障甄别更简易准确。
