摘要
传统方法在异常导航信号信噪比较低时对小型飞行器异常导航信号的检测效果不理想;设计并实现了一种基于3G-ASCX的小型飞行器异常导航信号检测系统,硬件设计时着重于ASCX传感器模块、异常导航信号检测模块、主控基站模块、3G/GPRS传输模块的研究,3G/GPRS传输模块的硬件设计中,通过功耗低体积小的CC1100完成异常导航信号的收发,传输过程中通过芯片STC12C5410AD完成电容的平衡转换,选取了MC3486进行电压的转换,最终实现异常信号数据的安全快速传输;最后进行仿真实验,实验结果证明,相比传统系统,所设计系统检测到的小型飞行器异常导航信号同实际测量的异常导航信号具有较高的匹配度,与实际值相比,误差小于1 dB,适合推广使用。
The traditional method in abnormal navigation signal in low SNR of abnormal small aircraft navigation signal detection effect is not ideal. Designs and realizes a kind of small abnormal aircraft navigation based on 3G--ASCX signal detection system, hardware design focuses on ASCX sensor module, abnormal navigation signal detection module, the master station module, 3G/GPRS transmission module, 3G/GPRS transmission module in the design of hardware and finished with a low power consumption small CCll00 abnormal navigation sig- nal to send and receive, in the process of transmission through the chip STC12C5410AD complete capacity equilibrium conversion, selected the MC3486 voltage conversion, finally realizes the abnormal signal data transmission safely and quickly. Finally, simulation experiments, the experimental results show that compared with the traditional system, the design system is detected by the small aircraft navigation signal with the actual measurement anomaly navigation signal with high compatibility, compared with the actual value, the error is less than 1 db, suitable for promotion.
