摘　　要：针对传统堤坝质量监测中,回波数据收发系统抗干扰性能较差的问题,提出一种基于DSP嵌入式技术的堤坝质量监测回波数据收发系统的设计方法,系统的硬件设备采用回波信号发射器与DSP嵌入式技术相结合;给出了射频模块、信号接收器模块和中央控制中心模块等关键设备的详细设计方案,软件算法设计中,通过算法判断系统中射频信号回波信号的强度,计算反馈射频衰减系数的干扰系数,并根据反馈射频信号干扰系数调整信号的补偿量,保证系统对信号接收的准确性;实验表明,该方法能够在强干扰下增强堤坝回波信息接收的准确性。According to the traditional dam quality monitoring, echo data transceiver system anti--jamming performance is poor prob- lems, the article proposes a kind of the dam quality monitoring echo data transceiver system design method based on DSP embedded technolo- gy, the system hardware equipment adopts echo signal transmitter and DSP embedded technologies, Gives the radio frequency module, signal receiver module and the central control center module detailed design scheme, software algorithm design, through the judgment system of ra- dio frequency signal echo signal strength, calculate feedback radio frequency attenuation coefficient of interference coefficient, and according to the feedback radio frequency signal interference coefficient adjust signal compensation quantity, guarantee system on the accuracy of the re- ceiving signal. Experiments show that this method can improve the strong interference in the dam echo information accuracy.
