基于智能手机的便携探鱼仪设计

Design of portable fish finder based on smart phone

根据超声波测距和目标判定原理,利用Wi-fi技术将手机APP和硬件相结合,设计了一款可供休闲娱乐的便携式探鱼系统。首先,超声换能器信号的收发控制和目标回波信号的获取利用集成芯片CC2500来实现。然后,根据回波信息和手机端的过门限检测算法计算出是否有鱼以及鱼的距离,并将A/D采样后的数据按自设置格式打包整理。最后,通过Wi-fi发送到智能手机上。经过测试表明,该探鱼系统能够根据回波信号判别目标,并清晰地显示在手机应用程序界面中。

According to the principle of ultrasonic distance measurement and target determination,Combine Wi-fi technology with mobile APP and hardware to design a portable fish retrieval system for recreation.First,the transmission and control of the ultrasonic transducer signal and the acquisition of the target echo signal are realized by using the integrated chip CC2500.Second,According to the echo information and the threshold detection algorithm,we can calculate the distance between the fish and the fish,and A/D sampling data from the self-format format package.Finally,it is sent to the smartphone through Wi-fi.The test results show that the fish exploration system can determine the target according to the echo signal,and clearly presented in the mobile application interface.
