管道机器人和地下传感器通过提供准确的传感数据在管道检测中发挥着重要作用。有些管道是金属制成的，埋在地下。在这种极端环境中的射频（RF）信号经历显著的传播损耗和不确定性。设计了一种管道机器人与井下传感器的混合式无线能量传输与无线通信系统。声信号用于无线能量传输。低频（LF）和高频（HF）磁场用于通过管道和近管道通信。全波模拟进行评估的性能。设计了一个软件定义的通信实验平台，采用QPSK调制方式进行低频和高频通信。对数据速率和无线信道进行了测量和分析。结果表明，在8mm厚的金属管道末端，距离为2cm，载波频率为100kHz时，最大数据速率为50kbps。
In-pipe robots and underground sensors play an important role in pipeline inspection by providing accurate sensing data. Some of the pipes are made of metal and buried underground. Radio Frequency (RF) signals in such an extreme environment experience significant propagation loss and uncertainty. This paper designs a hybrid wireless energy transfer and wireless communication system for in-pipe robots and underground sensors. The acoustic signals are used for wireless energy transfer. Low Frequency (LF) and High Frequency (HF) magnetic fields are used for through-pipe and near-pipe communications. Full-wave simulations are performed to evaluate the performance. A software-defined communication testbed is designed using QPSK modulation for LF and HF communications. The data rate and wireless channel are measured and analyzed. The results show that at the end of an 8 mm thick metal pipe, the maximum data rate is 50 kbps with a distance of 2 cm and 100 kHz carrier frequency.
