Description

Technical Field

[0001] The utility model relates to the technical field of rotating body signal transmission, and in particular to a rotating body signal transmission device based on terahertz communication. Background Art

[0002] With the continuous development of industrialization, automation and intelligence, robotic arms and robots have been gradually applied to production and life, assisting or even replacing humans in completing some work. Whether it is a robotic arm, a robot, or other equipment, there is an increasing demand for flexibility in order to complete more delicate operations. This requires the motion joints of these devices to have better flexibility and freedom.

[0003] In today's high-end industrial equipment, 360° continuous rotation is required, and multiple motions are also required on the rotating body. If there is motion, energy is needed, and at the same time, control signals and sensor feedback are also needed. Therefore, electromechanical equipment that can move freely during rotation must use a rotating connection device.

[0004] At present, the most commonly used rotating connection device is the slip ring. Slip rings are usually installed at the rotating center of the equipment and are mainly composed of a rotating part and a stationary part. The rotating part connects to the rotating structure of the equipment and rotates with it, called the "rotor", and the stationary part connects to the fixed structure of the equipment, called the "stator". Electrical signals and electrical energy are transmitted between the rotating part and the stationary part by sliding or rolling contact, electrostatic coupling or electromagnetic coupling of conductive parts.

[0005] In the prior art, as the types of controllers and sensors continue to increase and their accuracy continues to improve, the demand for data transmission volume of the equipment continues to increase, making it impossible for slip rings to meet the increasing signal / data transmission requirements at the rotating connections of the equipment.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0035] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0036] A rotating body signal transmission device based on terahertz communication, such as Figures 1 to 4 As shown, including

[0037] A rotating end transceiver assembly 1, a rotating structure 3 connected to an external electromechanical device;

[0038] A fixed-end transceiver assembly 2 connected to a fixed structure 4 located below a rotating structure 3;

[0039] The rotating end transceiver component 1 and the fixed end transceiver component 2 are connected in full-duplex communication.

[0040] In the prior art, the amount of data that the rotating connecting device needs to transmit is constantly increasing, and the corresponding number of lines is also increasing. If the huge number of lines is still connected through the slip ring 5, the design, processing and maintenance of the slip ring 5 will become more difficult, the volume and weight will be further increased, and the cost will also increase accordingly.

[0041] Specifically, the utility model provides a rotating body signal transmission device based on terahertz communication, which solves the problem of limited signal / data transmission volume of the slip ring 5 through full-duplex communication connection between the rotating end transceiver component 1 and the fixed end transceiver component 2, and meets the increasing signal / data transmission requirements of the continuous rotating body. As the amount of data increases further in the future, it is only necessary to replace a device with a faster transmission rate without replacing the structural parts of the rotating body, which reduces the difficulty and cost of equipment maintenance and upgrades.

[0042] In a preferred embodiment, the rotating end transceiver assembly 1 includes:

[0043] A rotating interface board 11, connected to the electrical circuit of the rotating structure 3;

[0044] The rotating baseband board 12 is located below the rotating interface board 11;

[0045] A rotating transceiver plate 13, located below the rotating baseband plate 12;

[0046] The fixed end transceiver component 2 includes:

[0047] A fixed interface board 21, connected to the electrical circuit of the fixed structure 4;

[0048] A fixed baseband board 22, located above the fixed interface board 21;

[0049] The fixed transceiver board 23 is located above the fixed baseband board 22 .

[0050] Specifically, the device is composed of a pair of transceiver components, which can be called a rotating end transceiver component 1 and a fixed end transceiver component 2, each of which is composed of a terahertz transceiver module, a baseband module and an interface module. The rotating end transceiver component 1 and the fixed end transceiver component 2 can be paired to complete full-duplex wireless transceiver.

[0051] More specifically, the rotating end transceiver assembly 1 and the fixed end transceiver assembly 2 are respectively installed on the rotating structure 3 and the fixed structure 4 of the device, and only need to be installed roughly opposite to each other, without special alignment. The interface modules of the rotating end transceiver assembly 1 and the fixed end transceiver assembly 2 are respectively connected to the electrical circuits of their respective mounting structures, the rotating interface board 11 is connected to the rotating structure electrical circuit 31, and the fixed interface board 21 is connected to the fixed structure electrical circuit 41, to obtain power and connect the wired circuit of the signal / data to be transmitted; the baseband module encodes and decodes the signal / data, and the transceiver module completes the transmission and reception of the signal.

[0052] In a preferred embodiment, a slip ring 5 is provided between the rotating structure 3 and the fixed structure 4. The slip ring 5 includes a rotor 51 and a stator 52 located below the rotor 51. The upper surface of the rotor 51 contacts the rotating structure 3, and the lower surface of the stator 52 contacts the fixed structure 4.

[0053] The rotating end transceiver assembly 1 is located inside the rotor 51 , and the fixed end transceiver assembly 2 is located inside the stator 52 .

[0054] Specifically, the design of the slip ring 5 enables signals or energy to be transmitted between the rotating structure 3 and the fixed structure 4, while keeping the relative positions of the rotating structure 3 and the fixed structure 4 unchanged, thereby realizing data transmission or energy transmission during the rotational motion, such as transmitting control signals or power signals in rotating mechanical equipment. At the same time, the transceiver component can be effectively protected from the influence of the external environment, thereby improving its stability and reliability.

[0055] In a preferred embodiment, the outer sides of the rotating end transceiver assembly 1 and the fixed end transceiver assembly 2 are both covered with a wave-transmitting housing.

[0056] Specifically, the wave-transmitting housing can play a protective and isolating role, protecting the transceiver components from the influence of the external environment, and at the same time can also reduce the impact of external interference on the transceiver components, thereby improving its working stability and reliability.

[0057] In a preferred embodiment, the diameter of the rotating end transceiver assembly 1 and the fixed end transceiver assembly 2 is less than 4 cm, and the height is less than 1.5 cm, so that the space size of the hollow part in the middle of the rotor 51 can be used for the slip ring 5 with a diameter of more than 4 cm and a height of more than 3 cm.

[0058] Specifically, the transceiver assembly can be made as small as possible, so that the user can choose a larger slip ring 5, and it is also applicable to slip rings 5 ​​of more sizes, thereby improving the stability and speed of data transmission. At the same time, the small diameter and low height transceiver assembly is also lighter and easier to install, which improves the convenience of use of the entire device.

[0059] In a preferred embodiment, the data transmission rate between the rotating end transceiver component 1 and the fixed end transceiver component 2 is greater than or equal to 3 Gbps.

[0060] Specifically, the increase in data transmission rate can help the system process data faster and improve the overall performance and response speed of the system.

[0061] In a preferred embodiment, a first transceiver chip is provided on a side of the rotating transceiver board 13 away from the rotating baseband board 12;

[0062] A second transceiver chip is provided on a side of the fixed transceiver board 23 away from the fixed baseband board 22 .

[0063] Specifically, the transmission and reception of signals can be better controlled, thereby improving the performance and efficiency of the entire system.

[0064] In a preferred embodiment, both the rotating end transceiver component 1 and the fixed end transceiver component 2 are terahertz communication boards.

[0065] Specifically, terahertz communication technology has a higher frequency and bandwidth, can achieve high-speed data transmission, and is suitable for scenarios that require large amounts of data transmission. Terahertz communication technology has lower energy consumption, which helps save energy and reduce costs.

[0066] To be more specific, terahertz communication technology does not generate electromagnetic radiation during the transmission process, has high security, can protect communication content from being stolen or interfered with, and has strong versatility and flexibility.

[0067] More specifically, terahertz communication technology has strong anti-interference capabilities in complex environments and can perform communication transmission stably and reliably.

[0068] In the first embodiment, a pair of transceiver components of the rotating body signal transmission device: a rotating end transceiver component 1 and a fixed end transceiver component 2 are respectively installed on the fixed structure 4 and the rotating structure 3 of the equipment, connected to the electrical circuits of the respective installation structures to obtain power, and connected to the wired circuits of the signals / data to be transmitted, so that the slip ring 5 only needs to complete the transmission of energy (power) at the rotating part through 2 to 3 wires, and the transmission of signals / data is completed by wireless transmission of this device.

[0069] Specifically, if the data volume is upgraded, the data format is changed or repaired, only the transceiver components need to be replaced, and there is no need to change the structural parts and the slip ring 5. When designing the equipment, there is no need to worry too much about the selection and volume of the slip ring 5 caused by the data volume.

[0070] The utility model adopts a wireless signal transmission mode to replace the sliding contact signal transmission mode in the slip ring 5. At the same time, in order to meet the needs of large-throughput data / signal transmission, the terahertz frequency band is selected for wireless communication.

[0071] Specifically, the terahertz frequency band has very rich spectrum resources, and the available working bandwidth may be as high as tens of GHz. The use of ultra-large bandwidth resources enables the terahertz communication system to support ultra-high communication rates. At present, the highest single-stream rate supported by terahertz communication with a working frequency band below 300GHz can reach 100Gbps, which is far higher than the average single-stream rate of about 1Gbps for Wi-Fi and 5G mobile communications, and it is expected that the terahertz communication rate may reach the Tbps level in the future. This device can achieve ultra-high transmission rates through terahertz communication technology to meet the increasing demand for transmission of high-precision sensing and other data.

[0072] At the same time, the device uses terahertz communication to wirelessly transmit data / signals at the rotating structure 3. Since the transmission distance requirement is relatively low (maybe only centimeters), the beam width can be relatively large and the power consumption can be relatively low. Therefore, the relative installation position requirements of the signal transceiver module can be greatly reduced, and the difficulty of designing, processing, assembling and later maintenance and upgrading of the equipment using the device can be greatly reduced.

[0073] In summary, the present application provides a rotating body signal transmission device based on terahertz communication, with a data transmission rate of more than 3Gbps, small size, light weight, and relatively free installation position. It can support full-duplex wireless transmission and full-rotation applications. It can also be widely used in slip rings 5, turntables, robotic arms and other equipment for high-speed data transmission at rotating structures 3.

[0074] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
