Signal transmission method of multi-channel wireless slip ring and wireless slip ring transmission system

Abstract

The invention provides a signal transmission method of a multi-channel wireless slip ring and a wireless slip ring system using the signal transmission method. By adopting the signal transmission method of the multi-channel wireless slip ring provided by the invention, the rotor wire and the stator wire in the wireless slip ring are not conducted with each other, and signal transmission is carried out by utilizing radio wave radiation. Multiple loops of the wireless slip ring can be used at the same time, and crosstalk between the loops is reduced through an interval valuing method of setting a safe frequency band between the loops; besides, according to the signal transmission method of the multi-channel wireless slip ring, the transmission efficiency of the channel can be effectively improved and the transmission reliability of the multi-channel slip ring can be improved by setting the high carrier frequency for the loop with the high priority.

Description

technical field [0001] The invention relates to the technical field of data communication and transmission, in particular to a signal transmission method of a multi-channel wireless slip ring and a wireless slip ring transmission system. Background technique [0002] Rotational communication is a way of transmitting signals between two structures that rotate relative to each other. With the advancement of science and technology, in key equipment such as modern military industry, electronics, aviation, electric power, metallurgy, petrochemical industry, communication, network monitoring and intelligent manufacturing, a variety of rotating structures need to be used in large quantities, and signals and energy are carried out in these rotating structures.

Problems solved by technology

However, this kind of contact slip ring has the following defects: because the brush and the electric ring are always in a state of friction when they rotate relative to each other in the two rotating mechanisms, the brush and the electric ring communicate through physical contact

Limited by device cost or hardware performance, the maximum operating frequency of the system is limited, and its transmission bandwidth is also limited. In some applications, a single loop cannot carry the required transmission rate. In this case, a combination of multiple loops is required. transmission
