Therefore, the features defined as "first", "second" can explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "multiple" is two or more than two, unless otherwise explicitly specified and limited.

[0024] In the utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "connection", "fixing" and the like should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or indirectly connected through an intermediate medium, it can be the communication inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0025] The utility model embodiment provides a kind of intelligent glasses data transmission system, as shown in Figure 1 The intelligent glasses data transmission system includes: main control module 1, glasses module 2 and transmission line 3. Wherein, the transmission line 3 is Type-C line, Type-C is a kind of general interface standard, full name is USB Type-C, it is a kind of interface specification. Glasses module 2 can collect image data, and the collected image data is transmitted into main control module 1 by transmission line 3. Main control module 1 is used to receive and process the image data that glasses module 2 is transmitted by transmission line 3, and the video data after processing is transmitted into glasses module 2 again by transmission line 3, so that glasses module 2 receives and displays the video data that is transmitted by main control module 1 by transmission line 3. It needs to be explained that the video data can be divided into two, respectively transmission is given to the left and right two display screens of glasses module 2 for imaging.

[0026] In the utility model embodiment, only by a transmission line 3 (i.e. Type-C line) can realize that the picture data that glasses module 2 is shot is transmitted to main control module 1, and the data that needs to be displayed on lens is reversely transmitted from main control module 1 to glasses module 2, i.e. it is realized that the video stream data of two directions is transmitted between two separate devices. The problem that traditional scheme needs complex wire harness interconnection, transmission distance is short and wearing is inconvenient is solved. The present scheme compares the design that traditional wire harness and module are integrated, has the advantages of convenient disassembly and maintenance.

[0027] Optionally, as shown in Figure 1 The main control module 1 includes: first power supply interface 11, and the glasses module 2 includes: second power supply interface 21. The first power supply interface 11 and the second power supply interface 21 are powered by the transmission line 3.

[0028] Optionally, the master module 1 comprises a serializer 12, and the glasses module 2 comprises a deserializer 22. The serializer 12 is configured to serialize the parallel video data (i.e. the video data to be transmitted back to the glasses module 2 and displayed on the lenses) and transmit the serialized video data in a serial manner through the transmission line 3. The deserializer 22 is configured to receive the serialized data transmitted through the transmission line 3 and deserialize the serialized data to restore the video data (e.g. the parallel video data without serialization). Further, referring to Figure 2 Figure 2 The glasses module 2 is shown to process the encoded video data. It can be understood that after receiving the video data from the master module 1, the glasses module 2 decodes the video data through the decoding chip of the deserializer 22, divides the video data into two parts, and transmits the two parts to the left and right display screens of the smart glasses for imaging.

[0029] The embodiment of the utility model is based on the serializer 12 and the deserializer 22 respectively built in the master module 1 and the glasses module 2, can adopt video data serialization and deserialization technology, reduces the number of transmission lines, improves the transmission distance, and improves the anti-interference ability of the product.

[0030] The conventional standard video high-definition video transmission protocol (for example, DP / HDMI) needs to pass through multiple pairs of differential lines to realize bidirectional data transmission, and only one Type-C line can realize unidirectional video transmission. In order to reduce the line, the embodiment of the utility model adopts a video encoding technology (V-by-one). Specifically, as shown in Figure 1 The master module 1 comprises a high-speed serial digital interface 13 for the flat panel display and facing the image transmission, i.e. the high-speed serial digital interface 13 is an interface adopting the V-by-one high-speed serial interface technology, and through V-by-one, only one set of differential lines can realize the transmission of the video signal (as shown in Figure 3 The MIPI is the abbreviation of Mobile Industry Processor Interface, which is a kind of mobile industry processor interface, and compared with the previous LVDS (Low Voltage Differential Signaling, low voltage differential signal), the number of signal lines can be greatly reduced, which is helpful for the realization of the solution of "low cost", "low EMI (Electromagnetic Interference)", "lightweight".

[0031] ​Optionally, the glasses module 2 comprises a complementary metal-oxide-semiconductor 23, namely CMOS (Complementary Metal-Oxide-Semiconductor). The complementary metal-oxide-semiconductor 23 (CMOS) collects the target area image to obtain raw image data.

[0032] In practical applications, the interface of the CMOS output data is a parallel interface, and a plurality of data lines are also required to realize parallel data transmission. In long-distance transmission, there are disadvantages such as poor anti-interference ability and high EMI, and the parallel interface is usually used for short-distance transmission within a system. In order to overcome this difficulty, further, the glasses module 2 of the utility model embodiment further comprises a digital signal processor 24 and a universal serial bus interface 25. The digital signal processor 24 is a DSP (Digital Signal Processor) processor, and the universal serial bus interface 25 is a USB (Universal Serial Bus) interface.

[0033] The digital signal processor 24 (DSP) is used for pre-processing the raw image data output by the complementary metal-oxide-semiconductor 23 (CMOS), and transmitting the pre-processed data to the master module 1 through the universal serial bus interface 25 (USB) by using a standard UVC (USB Video Class, a USB device class standard) video protocol. That is, the video signal transmission collected by the CMOS can be realized through a set of USB differential signals. At the same time, after the image is pre-processed by the front-end dedicated DSP processor, the overhead of the image processing of the master module 1 can be reduced, the efficiency can be improved, and the delay can be reduced.

[0034] In addition to realizing image and video collection and display, the smart glasses also need some auxiliary functions to obtain better user experience and solve application problems.

[0035] Optionally, the master module 1 further comprises a first synchronous / asynchronous serial communication protocol interface 14, and the glasses module 2 further comprises a second synchronous / asynchronous serial communication protocol interface 26. Specifically, the synchronous / asynchronous serial communication protocol interface is an IIC / UART interface.

[0036] The first synchronous / asynchronous serial communication protocol interface 14, the transmission line 3 and the second synchronous / asynchronous serial communication protocol interface 26 connected in sequence can realize the data and command interaction between the master module 1 and the glasses module 2 through an independent low-speed bus (a low-speed bus independent of the video transmission channel).

[0037] Specifically, as shown in FIG. 2, the first synchronous / asynchronous serial communication protocol interface 14 of the master module 1 is connected to the second synchronous / asynchronous serial communication protocol interface 26 of the glasses module 2 through the transmission line 3. Figure 4As shown, the host module 1 communicates with the processor (such as a DSP processor) on the glasses module 2 through a first synchronous / asynchronous serial communication protocol interface 14 (such as IIC) for controlling the infrared light of the smart glasses to turn on or off.

[0038] In addition, the processor (such as a DSP processor) of the glasses module 2 detects the state of the encoder (such as a position encoder on the glasses module 2 for adjusting the position of the picture), and when the operator rotates the encoder, the processor sends the current encoder position information to the host module 1 through a second synchronous / asynchronous serial communication protocol interface 26 (such as IIC) to enable the host module 1 to adjust the position of the real picture through the encoder position information.

[0039] From the above, it can be seen that the embodiments of the utility model can solve the data transmission problem of smart glasses (such as split type AR glasses) through a transmission line 3 (Type-C line), and the scheme also supports positive and negative insertion (that is, the positive and negative surfaces of the transmission line 3 plug are not distinguished, the positive and negative surfaces are inserted normally, and the two ends of the transmission line 3 are not distinguished, either end of the glasses module 2 is connected, and the other end of the host module 1 is connected, and normal transmission is achieved), and replacement (in the case of transmission line 3 damage, without disassembly, pull out the two ends of the transmission line 3 plug, and replace the new transmission line 3). It can be understood that the embodiments of the utility model integrate the communication interfaces of V-by-one, USB, IIC / UART and power supply on a transmission line 3 line, solve the problems of complex wire harness interconnection, short transmission distance and inconvenient wearing of the traditional scheme. The scheme has the advantages of convenient disassembly and maintenance compared with the traditional wire harness and module integrated design. It should be noted that the smart glasses data transmission system provided by the embodiments of the utility model can be used for smart glasses type blood vessel imaging instruments, for example, the host module 1 is responsible for receiving the blood vessel image data transmitted by the glasses module 2 through the transmission line 3, and after image cropping, algorithm processing and other processes, the blood vessel information is identified, and the processed blood vessel image is encoded and then transmitted to the glasses module 2 through the transmission line for real-time display.

[0040] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the technical field can easily think of changes or replacement technical solutions within the technical range disclosed by the utility model, which should be covered within the protection scope of the utility model. Therefore, the protection scope of the utility model should be subject to the protection scope of the claims.
