Technical Field

Background
Photoelectric slip rings are commonly used to transmit electrical, optical signals between relatively rotating parts, ensuring the normal transmission of energy or signals in a rotary connection. The smooth ring is generally arranged at the center of the via hole electric slip ring, and the optical slip ring and the electric slip ring coaxially and synchronously rotate, so that high-definition video signals and the like can be transmitted. When the optical fiber transmits signals, the service life is long because of non-contact coupling in the rotary connection. The photoelectric slip ring has another structure, and an optical fiber or an optical fiber collimator is directly placed in the through hole conductive slip ring to form a compact one-optical-multiple photoelectric slip ring.
The existing photoelectric slip ring is complex in structure, particularly a smooth ring, can not reliably realize simultaneous transmission of single-mode, multi-mode signals and electric signals, can only optimize optical signals with certain frequencies, can not guarantee that the attenuation rate meets the use requirement while rotating, particularly the distributed optical fiber logging has strict requirements on insertion loss and loss fluctuation, and the loss change causes the logging signal-to-noise ratio to not meet the use requirement. The design of the optical slip ring and the electric slip ring has simple structure, can carry out mixed loading of the single-mode optical slip ring and the multi-mode optical slip ring, and can meet the actual use requirements of loss and loss fluctuation.
The full-distributed optical fiber sensor has the unique advantages of electromagnetic interference resistance, low loss, radiation resistance, small volume, easy layout and the like, and can realize full-directional uninterrupted embedded nondestructive monitoring on the stress, strain, temperature, displacement, vibration and the like of an oil well, but has the defects of low spatial resolution and the like; the conventional electrical logging has the advantages of complete series, high measurement precision, high spatial resolution and the like, but cannot be used for full-time and full-space dynamic monitoring. The existing device can only transmit one optical signal and can not transmit single-mode and multi-mode signals simultaneously, so that a reliable device is needed to simultaneously meet the transmission of multiple optical signals and electrical signals.
