近年来，无线能量传输(WPT)已广泛应用于能源、医疗、通信等诸多领域，成为电磁领域的一个研究热点.WPT相比有线传输具有更高的灵活性和安全性，但目前仍存在设备替换和维护费用高等问题.本文设计并实现了一套基于USRP的无线能量通信系统，并结合电磁感应原理开发了用于金属探测的计数装置.通过单摆实验验证，成功监测和记录了金属球的摆动行为，证明了系统在检测金属目标方面的可行性和有效性.此外，本文还探索了USRP在信号处理和通信系统中的广泛应用潜力，展示了其在提升系统灵活性和性能方面的优势.

 In recent years, wireless power transmission (WPT) has been widely applied in various fields such as energy, medical, and communication, becoming a research hot spot in the electromagnetic domain. Compared to wired transmission, WPT offers greater flexibility and safety; however, issues like high costs for equipment replacement and maintenance still exist. This paper presents the design and implementation of a wireless energy communication system utilizing Universal Software Radio Peripheral (USRP) technology, along with the development of a counting device for metal detection based on electromagnetic induction principles. Through a pendulum experiment, the system successfully monitored and recorded the oscillation behavior of a metal ball, demonstrating its feasibility and effectiveness in detecting metallic targets. Additionally, this paper explores the extensive application potential of USRP in signal processing and communication systems, highlighting its advantages in enhancing system flexibility and performance.
