Non-contact frequency domain electrical method real-time advanced detection system and method for shield carrying

The invention discloses a non-contact frequency domain electrical method real-time advanced detection system and method for shield carrying. Non-contact electrodes are installed on a cutterhead of a shield machine, currents are emitted and received by means of capacitance coupling, the non-contact electrodes are connected to a host through a plurality of paths of swivel joints, measurement data is inverted and explained in real time, a prediction result is transmitted to a shield machine control system, and technical support is provided for safe construction of the shield machine. According to the invention, the Non-contact electrodes are installed on the shield machine cutterhead, the problem of difficult coupling of conventional contact electrodes is avoided; the real-time advanced detection of the geology in front of a tunnel face is realized in a shield driving process without the downtime of the shield machine, the rapid requirement of shield construction is met, and the efficiency of advanced geology detection of the shield machine is substantially improved; the electrodes are only installed on the cutterhead, the interference of back metal objects is effectively avoided, the forward advanced detection capability is improved, and more important, the problem that the spaces of the cutterhead and the tunnel face are very narrow is solved.
