求翻译：核心思想是把电源逆变技术应用到井下发射系统，产生井下激励信号，将井下的激励信号以油管和套管作为传输信道以无电缆的方式进行数据传输技术。是什么意思？

The core idea is to power inverter technology to underground transmission system, resulting in down-hole excitation signal, the excitation signal to the downhole tubing and casing as the transmission channel to free cable for data transmission technology.

The core idea is the application of technology to power inverter silo launch systems, and have a downhole inspire signal, Wells will be inspired by the signal to pipeline and casing as transmission channel to a cable of data transmission technology.

The core thought is applies the power source inversion technology the silo shot system, produces the mine shaft drive signal, transmits the mine shaft drive signal by the drill tubing and the drive pipe achievement the channel to carry on by the non-electric cable way the data transmission technolog

Core idea is the inverter power supply technology applied to launch systems, downhole excitation signal, stimulus signals of underground tubing and casing as a transport channel data transmission technology in cable-free way.

The core message is to apply the power to in the pit launching the system against turning into the technology, produce in the pit encouraging signalling, encouragement signal by oil pipe and telescopic to carry on the transmission technology of the data in a manner to without the cable as transmit t
