摘要
为了满足便携式成像声呐硬件电路低功耗、小体积的要求,针对接收部分提出一种设计方案,实现48路声呐回波信号的调理和采集。在实现电路性能的基础上,一方面采用单电源的工作模式,降低接收电路的功耗;另一方面设计并优化接收信号链路和电路拓扑结构,减小接收电路PCB尺寸,最终降低整机的功耗和体积。通过仿真和测试,验证了该接收电路的可行性。
In order to meet the requirements of low power consumption and small size of portable imaging sonar hardware circuit,a design scheme is proposed for the receiving part to realize the conditioning and acquisition of 48 sonar echo signals.On the basis of realizing the circuit performance,on the one hand,it adopts the working mode of single power supply to reduce the power consumption of the receiving circuit;On the other hand,design and optimize the receiving signal link and circuit topology,reduce the PCB size of the receiving circuit,and finally reduce the power consumption and volume of the whole machine.Through simulation and test,the feasibility of the receiving circuit is verified.
