Abstract

The invention relates to an electromagnetic telemetry system and method, which solves the technical problems of low data transmission efficiency and low bandwidth utilization rate. By adopting a transmitter including a central processing unit and a plurality of transmission channels; each transmission channel is connected to the central processing unit connection; the transmitting channel includes a time delay encoder, an nω×N multiple selection coupler connected to the time delay encoder, and a multi-order amplitude electro-optical conversion module connected one by one to the N output terminals of the nω×N multiple selection coupler , the optical phase modulators connected to the multi-order amplitude electro-optical conversion modules one by one, all the optical phase modulators are connected to a wavelength division multiplexer after being connected, and the wavelength division multiplexer is connected to an optical fiber; the transmitting channel is also set There is a temperature detection unit and a timing unit, and the technical solution that the temperature detection device and the timing device are both connected to the central processing unit solves this problem well and can be used in electromagnetic telemetry applications.

Description

technical field [0001] The invention relates to the field of electromagnetic telemetry, in particular to an electromagnetic telemetry system and method. Background technique [0002] Telemetry is a technology that transmits close-range measurements of object parameters to distant measurement stations to achieve long-distance measurements. Telemetry technology is a new type of technology with good integration performance, good tracking performance and remote control performance. A comprehensive technology that transmits to a long-distance measuring station to realize long-distance measurement. [0003] The existing electromagnetic telemetry has the technical problems of low data transmission efficiency and low bandwidth utilization. Therefore, it is necessary to provide an electromagnetic telemetry system and method with high efficiency. Contents of the invention [0004] The technical problem to be solved by the present invention is the technical problem of low data tran...
