摘要
提出了一种基于混合信号系统级芯片(SoC)和复杂可编程逻辑控制器(CPLD)的数字化三轴磁通门传感器信号调理系统。利用硬件完成对信号的采集、滤波处理、传输等功能,并编写了相应的数据处理算法,从而降低了成本,缩减了面积。实验结果表明:与传统磁通门传感器相比,误差减小,温度性能与输出稳定性得到了改善。
A signal disposal system based on SoC and CPLD digital triaxial fluxgate sensor was proposed. The signal was collected, processed and transmitted through the hardware circuit, and proper data disposal arithmetic was compiled. It can reduce the cost and area. The experimental result indicates that the error is small, and it can improve the temperature property and output stability compared to the traditional fluxgate sensor.
