针对航空测试中常用的同步器信号,提出一种基于嵌入式系统的双通道同步器信号采集系统。系统以同步器专用芯片对信号进行预处理,解析出数字量的角度和角速率,以FPGA为控制器进行数据处理,实现两路角度和角速率测量功能。经过仿真实验和系统调试,结果表明此系统能够稳定高效的采集和处理同步器信号。
Aiming at the synchronizer signal commonly used in aviation testing, a dual-channel synchronizer signal acquisition system based on embedded system is proposed. The system preprocesses the signal with the special chip of the synchronizer, analyzes the angle and the angular rate of the digital quantity, carries on the data processing with FPGA as the controller, realizes the function of two angles and angular rate measurement. After simulation and system debugging, the results show that the system can collect and process the synchronizer signal stably and efficiently.
