[0030] Embodiment 1

[0031] According to an embodiment of the present invention, a relay cable is provided, which is mainly used in an augmented reality system to connect an augmented reality device and a host computer for data transmission between the two. As Figure 1 shown, the relay cable 10 includes: a cable 20 and a repeater 30, where: at least one repeater 30 is provided on the cable 20, one end of the cable is used to connect to the augmented reality device, and the other end of the cable is used to connect to the host computer of the augmented reality device.

[0032] In an actual application scenario, there is a certain distance limit for the transmission distance between the augmented reality terminal and the host computer. When the transmission distance between the augmented reality terminal, such as an AR glasses, and the host computer is greater than 2 meters, data transmission cannot be completed only relying on the cable between the AR glasses and the host computer. And in some special scenarios, this transmission distance will be further reduced. In this regard, in this embodiment, by setting at least one repeater on the cable, the attenuation of the transmission signal can be reduced or avoided, so as to overcome the problem of unclear data transmission caused by too long a transmission distance.

[0033] It should be noted that the host computer in the embodiments of the present invention generally refers to a computer that can issue control commands, and various signal changes can be displayed on the screen. It can generally be a PC, or a host computer, or a master computer, or an upper computer.

[0034] Optionally, in this embodiment, a repeater 30 is provided on the cable 20. Among them, as Figure 2 shown, the distance R between one end 202 (the augmented reality device side) of the cable 20 and the repeater 30 is less than the first preset transmission distance. It should be noted that the first preset transmission distance can be the maximum transmission distance supported by the transmission cable used by the augmented reality terminal (for example, a value of two meters or more). It should be noted that in this embodiment, the specific material of the cable is not limited.

[0035] Optionally, in this embodiment, as Figure 2 shown, the cable 20 includes a data input channel 210 and a data output channel 212. The repeater 30 is provided on the data input channel 210 at one end 202 of the cable. Among them, the data input channel 210 and the data output channel 212 are determined according to the data flow direction in the cable 20.

[0036] It should be noted that in the above embodiments, it is mainly for some one-way transmission protocols, such as the DP protocol. And in some embodiments, for two-way propagation protocols, such as the USB3.0 protocol, a data sending repeater and a data receiving repeater need to be placed at the data input end and the receiving end respectively.

[0037] Specifically, the cable in this embodiment is actually a two-way transmission cable, which has a data input channel and a data output channel. The data input channel and the data output channel are actually relative to the cable and are determined according to the data flow direction of the data transmitted in the cable. As Figure 2As shown in the figure, the data input channels and data output channels at both ends of the cable are opposite. The AR glasses at one end of the cable send their own transmission data through the data input channel 210 and receive the transmission data from the host computer through the data output channel 212. For the other end of the cable, the data input channel 210 becomes the data output channel, and the data output channel 212 becomes the data input channel. In this embodiment, actually, it is only for the convenience of description to define the channels at both ends of the cable. In fact, it still needs to be determined according to the data flow direction of the transmission data.

[0038] Optionally, in this embodiment, as Figure 3 shown, one end 202 of the cable 20 is connected to the augmented reality device 40; the other end 204 of the cable 20 is connected to the host computer 50 of the augmented reality device 40.

[0039] Normally, the AR glasses are connected to the host computer through a relay cable. A repeater is provided on the data input channel on the side of the relay cable connected to the AR glasses to enhance the signal of the data sent by the AR glasses, that is, the input data received by the relay cable.

[0040] Optionally, in this embodiment, as Figure 4 shown, when the length of the cable is relatively long, for example, when the length of the cable exceeds two meters, two repeaters 30 can be provided on the cable 20. Specifically, it can be a first repeater (which can be a USB3.0 repeater) and a second repeater (which can be a DP repeater). Among them, the sending part of the DP repeater and the USB repeater is integrated on the first printed circuit board PCB, and the receiving part of the USB repeater is integrated on the second PCB. Among them, the distance between the first PCB and the host computer is less than the second preset transmission distance, and the distance between the second PCB and the augmented reality device is less than the third preset transmission distance. Optionally, the second preset transmission distance can be a value greater than 0 and less than 2 meters, and the third preset transmission distance can also be a value greater than 0 and less than 2 meters.

[0063] Optionally, in this embodiment, as Figure 5 shown, the first repeater 302 is disposed in the data input channel 210 at one end 202 of the cable 20; the second repeater 304 is disposed in the data input channel 220 at the other end 204 of the cable 20.

[0064] Compared with the relay cable in the above embodiment, in this embodiment, repeaters are provided on both sides of the relay cable to achieve signal enhancement of the input data on both sides respectively. The relay cable with a repeater on one side in the above embodiment is generally used in application scenarios where the augmented reality device does not have signal enhancement and the host computer side has signal enhancement. The relay cable with repeaters on both sides, however, can be applied to most application scenarios and can achieve signal enhancement of the input data on both sides of the augmented reality device and the host computer.

[0065] For example, in some embodiments, the AR glasses are connected to the host computer through a standard TYPE-C cable. Among them, the TYPE-C cable uses the alt mode, and in this mode, it can support three protocols, namely DP, USB2.0, and USB3.0, to work simultaneously. Among them, since the data transmission rate supported by the USB2.0 protocol is relatively low, relay signal enhancement may not be used. However, when the data transmission speed under the DP protocol and the USB3.0 protocol reaches more than 5 Gbps, when the used wire is long or thin, the signal attenuation is very large, and a repeater needs to be added to ensure the signal integrity during the data transmission process.

[0066] In view of the above situation, in this embodiment, as Figure 6 shown, a repeater is added to the TYPE-C cable connecting the AR glasses and the host computer HOST. Among them, the position of the repeater is close to the receiving end of the signal transmission. The DP protocol repeater and the USB3.0 protocol repeater transmitter are placed on a single PCB circuit board, and the USB3.0 relay receiver uses a separate PCB circuit board; since USB3.0 data is bidirectional, a new circuit board is placed at the receiving and transmitting ends respectively. Among them, in order to reduce the power consumption of the glasses, the power supply of the repeater is supplied from the HOST (host computer).

[0067] In another alternative embodiment, the structures of the above two repeaters are described below:

[0068] The structure of the USB3.0 repeater is as Figure 7As shown in the figure, where SSRX_IN is the signal input port of the USB3.0 repeater, and SSRX_OUT is the signal output port of the USB3.0 repeater. VCONN is the power supply port for the repeater, which is powered by the HOST side. The CC port is used to detect the insertion of a device. When no device is inserted, the chip enters the low-power state. The SBU1 port and the SBU2 port are used as the interfaces of the I2C chip to provide chip download and configuration.

[0069] The structure of the DP repeater is as Figure 8 shown. The working principle of the DP repeater is similar to that of the USB repeater. It can amplify two DP signals simultaneously, corresponding to the ALT mode standard of the TYPE-C cable.

[0070] In the above embodiments, the USB3.0 repeater and the DP repeater are adopted, with simple power supply and low power consumption. Since the sizes of the repeaters are relatively small, both integrated circuit (IC) chips are in ball grid array (BGA) packages, which are very suitable for lightweight products such as AR glasses.

[0071] Through this embodiment, by setting a repeater on the relay cable, the augmented reality device is connected to the host computer through the relay cable, avoiding the attenuation of the transmission signal caused by the long distance between the augmented reality device and the host computer, thereby achieving the technical effect of stable data transmission between the augmented reality device and the host computer.
