the wireless transmission mode allows the two communication parties to be in independent states, and the relative motion states of the two communication parties generally do not affect the quality of signal transmission, for example, when one communication party is in relative motion, the other communication party is in relative rest, or when the two communication parties are in relative motion, signals can be transmitted between the two communication parties relatively completely; however, the wireless transmission method is limited by the effective transmission distance of the signals of the corresponding communication method.
The wired transmission mode can directly transmit signals and energy from one communication party to the other communication party through cables or other physical connection media; however, since the wired transmission requires an actual cable or other physical connection media, both communication parties need to be in a relatively static state to ensure stable transmission of signals without the occurrence of winding, abrasion and the like; this imposes a great restriction on the working state of both parties of signal transmission, resulting in great inconvenience in engineering application.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Based on the description of the background art, in view of the shortcomings of the wired transmission, some solutions of the prior art insert a relay connection device, such as a conductive slip ring, a magnetic ring, etc., into the actual physical connection medium, and the relay connection device can allow the two ends of the connected communication to perform signal transmission in the presence of relative movement (such as rotation).
The conductive slip ring belongs to the application range of electrical contact sliding connection, and realizes transmission of signals and energy under the rotating condition in a sliding contact mode; referring to fig. 1, fig. 1 is a schematic diagram comparing before and after use of a conductive slip ring, where the conductive slip ring is an electrical component responsible for communicating a rotating body and transmitting energy and signals, and the conductive slip ring is generally installed at a rotation center of an apparatus and mainly consists of two major parts, namely a rotating part and a stationary part; in which the rotating part is connected to the rotating structure of the device and moves rotationally therewith, called "rotor", and the stationary part is connected to the energy source of the stationary structure of the device, called "stator". In this regard, the conductive slip ring apparatus may be used in any electrical system requiring unlimited continuous rotation for transmitting power and data signals from a fixed structure to a rotating structure. The magnetic ring realizes the radiation transmission of signals through the electromagnetic induction principle, belongs to one type of wireless transmission, and is added in a connecting link in a way of combining wired connection and wireless connection to jointly realize the transmission of signals and energy; specifically, the magnetic ring is composed of two magnets and a connecting cable, the two magnets are relatively close to each other, the magnets are connected through a lead, and the purpose of signal rotation transmission is achieved in an electromagnetic induction mode; the two magnets can rotate relatively, one is relatively static, or both can rotate relatively, but the distance between the two magnets can greatly affect the transmission efficiency of signals.
At present, in the prior art, the scheme of multi-channel signal and energy rotation transmission mainly uses multi-channel slip ring transmission, but the multi-channel slip ring transmission is limited by the size of a slip ring structure, and the distance of signal transmission links among multiple channels is relatively small, so that the problem of relatively serious inter-channel interference easily exists.
The magnetic ring transmission depends on the electromagnetic induction principle, and the multi-channel transmission can cause the problem of signal distortion or serious attenuation caused by mutual induction or inhibition of signals, so that the fidelity of multi-channel signal transmission cannot be ensured by a single slip ring or magnetic ring transmission scheme; meanwhile, the transmission efficiency of signals and energy through the magnetic rings is limited by the distance between the magnetic ring pairs, and the attenuation value is greatly improved due to the increase of the distance.
Based on the above, the coupling device formed by combining the magnetic ring coupling unit and the slip ring coupling unit is added to the wired transmission link of the signal and the energy, so that the purpose of multi-channel signal rotation transmission is achieved, and the matched coupling units are added to the multi-channel signal and energy transmission link through channels, so that the independence among multiple channels can be ensured, and the problem of interference among multiple channels is effectively avoided; based on the independence among the coupling units, the fidelity of the signal can be effectively improved; meanwhile, the insertion positions of the coupling units can be debugged according to the connection requirements among the coupling units, so that the whole structure has more flexibility; the method can be carried out in a mode of a slip ring coupling unit at a position with a longer signal coupling distance, and the defect that the transmission distance of a magnetic ring is limited is effectively overcome.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

As can be seen from the above description, in the process of transmitting multi-channel signals and energy, the interference of signals between different channels is easily caused due to space limitation and circuit layout and wiring constraints among multi-channel slip rings in the prior art; according to the multi-channel signal and energy transmission device provided by the embodiment of the application, each channel is independently carried out, or enough shielding distance is reserved between the channels, so that the crosstalk of signals can be effectively reduced. Furthermore, in the prior art, the multi-channel slip ring is limited by the structural constraint of the multi-channel slip ring, and the coupling device can be inserted into the whole signal transmission link at only one position, but the multi-channel signal and energy transmission device provided by the embodiment of the application can be added into the coupling device at any position of each channel according to the transmission requirement of the signal and energy of each channel, so that the system has stronger flexibility.
