Transmission system and transmission method of non-contact magnetic signals in high hydraulic environment

Abstract

The invention discloses a transmission system and a transmission method of non-contact magnetic signals in a high hydraulic environment. The system comprises a magnetic pulse transmitting circuit of which the receiving end is electrically connected with a signal wire and the transmitting end is clung and fixed in the inner side of the wall of an austenite stainless steel chamber; a magnetic pulse generating circuit is covered by an inner metal net; a signal wire is electrically connected with the inner metal net through a first high-frequency band-pass filter; a second high-frequency band-pass filter and multiple signal amplifying and transmitting circuits are clung and fixed outside the austenite stainless steel wall; the second high-frequency band-pass filter, the signal amplifying and transmitting circuits; and single-shaft magnetic sensors of which the number is the same are covered outside the austenite stainless steel wall through an outer metal net. The transmission method comprises the following steps: switching the signal transmitted through a conductor into a magnetic field signal which can be transmitted in space and can pass through the austenite stainless steel wall to reach a receiving part arranged on the external part of the chamber, and then switching the magnetic field signal into corresponding forms of data to be observed and recorded. With the adoption of the transmission system and the transmission method of the non-contact magnetic signals in the high hydraulic environment, partitioned transmission of the signals is realized and the problem that the wire signal transmission is limited is solved.

Description

technical field [0001] The invention relates to a non-contact magnetic signal transmission system, in particular to a non-contact magnetic signal transmission system and a transmission method thereof in a high hydraulic pressure environment.
