[0028] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure.

[0030] It should be understood that although the terms first, second, third, etc., may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0031] Figure 1 This is a structural block diagram of a data transmission device according to an exemplary embodiment. Figure 2 This is a structural block diagram of a signal transmitter according to an exemplary embodiment. Figure 3 This is a structural block diagram of a signal receiver according to an exemplary embodiment. For example... Figures 1-3As shown, the data transmission device includes a signal transmitter 101, a signal receiver 102, a camera module 103, and a processor 104. The camera module 103 is electrically connected to the signal transmitter 101, and the processor 104 is electrically connected to the signal receiver 102, so that data information between the camera module 103 and the processor 104 can be transmitted through the cooperation between the signal transmitter 101 and the signal receiver 102.

[0032] The signal transmitting end 101 includes a first lens group 1 and a light emitting module 2. The first lens group 1 is located at the front end of the light emitting module 2. The front-back direction can be defined according to the direction of the light transmitted by the first lens group 1. That is, in the forward direction of the transmitted light, the first lens group 1 is located in front of the light emitting module 2, so that the light emitted by the light emitting module 2 can be transmitted through the first lens group 1. The light emitting module 2 is electrically connected to the camera module 103. The light emitting module 2 can be used to convert the data information received from the camera module 103 into light signals and emit light carrying the data information. The emitted light is transmitted through the first lens group 1. Based on this, data information can be transmitted by means of light signals. Utilizing the principle of fast light transmission speed, the data signal transmission rate can be greatly improved, and it is also beneficial to improve the anti-interference capability during data transmission.

[0033] The signal receiver 102 includes a second lens group 3 and a photoelectric conversion module 4. The photoelectric conversion module 4 is located at the front end of the second lens group 3, meaning it can sense the transmitted light from the second lens group 3 and acquire an electrical signal carrying data information based on the sensed transmitted light. The photoelectric conversion module 4 is electrically connected to the processor 104, which can receive data information from the photoelectric conversion module 4, thus enabling data transmission between the camera module 103 and the processor 104.

[0034] For example, the image sensor of this camera module can transmit the acquired shooting information to the photoelectric emission module 2 via an interface. The photoelectric emission module 2 converts the electrical signal into a light signal, which is then transmitted through the first lens group 1 to the second lens group 3. The second lens group 3 further transmits the light, which is then sensed by the photoelectric conversion module 4. After conversion, the shooting information can be transmitted to the processor via the interface. This shooting information may include image information, video information, and shooting parameters, among other data.

[0035] The first lens group 1 and the second lens group 3 of the signal transmitter 101 are set with the same optical axis. Of course, the best case is that the optical axes of the first lens group 1 and the second lens group 3 are completely coincident. In fact, under the influence of assembly error and process error, a certain allowable error is allowed between the optical axes of the first lens group 1 and the second lens group 3. For example, the distance between the optical axis of the first lens group 1 and the optical axis of the second lens group 3 can be less than or equal to 1mm. That is, the optical axis of the second lens group 3 can be arranged at any position in a circular area with the optical axis of the first lens group 1 as the center and the radius as 1mm.

[0036] Based on this data transmission device, data information can be transmitted using optical signals. Due to the high propagation speed of light, data transmission efficiency can be effectively improved. The plane perpendicular to the optical axis of the first lens group 1 is the first plane, and the plane perpendicular to the second optical axis is the second plane. Ideally, the first and second planes can be arranged parallel to each other. Within the allowable error range, an angle of less than or equal to 2° is allowed between the first and second planes. The signal transmitting end 101 and the signal receiving end 102 can be fixed together as a single component using the same structural member. Alternatively, in other embodiments, the signal transmitting end 101 and the signal receiving end 102 can be fixed together as two separate components using different members. When subsequently assembled into a signal transmission device, other parts or components of the associated equipment can be used to limit the relative positional relationship between the two components, ensuring signal transmission.

[0037] In this embodiment, the output interface type of the photoelectric conversion module 4 can be the same as the input interface type of the light emitting module 2. For example, if the input interface type of the light emitting module 2 is a MIPI interface, and the output interface type of the photoelectric conversion module 4 is also a MIPI interface, then the light emitting module 2 can receive and send MIPI type data information through the MIPI interface, reducing data type conversion and optimizing resources. Of course, in other embodiments, the output interface type of the photoelectric conversion module 4 can be different from the input interface type of the light emitting module 2. In this case, a converter can be placed at the signal transmitting end 101 or the signal receiving end 102 to convert data types.

[0038] In some embodiments, the emitted light from the first lens group 1 can be scattered light, and the second lens group 3 can be used to expand the scattered light into parallel light. This facilitates the design of a regular optical path between the signal transmitter 101 and the signal receiver 102, and allows for a reasonable design of their relative positions, avoiding data signal loss due to emitted light loss. Furthermore, the first lens group 1 includes a single first lens, and the second lens group 3 includes a single second lens. The diameter of the first lens is smaller than the diameter of the second lens. This ensures that the parallel light beams formed by the expansion of the first lens can be further transmitted to the photoelectric conversion module 4 through the second lens, preventing data loss.

[0039] In the above embodiments, such as Figure 4 As shown, the light emitting module 2 may further include an encoder 21, a driver chip 22, and a light emitter 23. The driver chip 22 is electrically connected to the encoder 21 and the light emitter 23, respectively. The encoder 21 is used to encode the received data information. The driver chip 22 drives the light emitter 23 to emit light carrying the data information based on the acquired encoded data information. For example, the light emitter 23 may include a laser emitter, and the driver chip 22 may include a laser emitter chip. Electro-optical conversion can be achieved through the laser emitter chip 22 and the laser emitter 23, so that the data information is converted into an optical signal carrying the data information and transmitted through the first lens group 1.

[0040] Still with Figure 4 As shown, the photoelectric conversion module 4 includes a photoelectric sensor 41, a conversion circuit 42, and a decoder 43. The photoelectric sensor 41 is used to sense the transmitted light from the second lens group 3. The conversion circuit 42 is electrically connected to the photoelectric sensor 41 and is used to convert the current signal output by the photoelectric sensor 41 into a voltage signal carrying the data information. This conversion process is beneficial for subsequent amplification, filtering, and digitization processes. The decoder 43 is electrically connected to the conversion circuit 42 and is used to decode the voltage signal to obtain data information. Subsequently, the data information can be directly transmitted to the target object through the decoder 43.

[0041] The current value output by the photoelectric sensor 41 is greater than or equal to a preset threshold, which is the minimum current value required to extract data. This ensures that data information can be obtained based on the current signal output by the photoelectric sensor and subsequent calculations. The current value can be adjusted by changing the distance between the first lens group 1 and the second lens group 3, the transmittance of the medium to light, and the alignment between the first lens group 1 and the second lens group 3 to ensure it is greater than or equal to the preset threshold. For example, the current value output by the photoelectric sensor 41 can be greater than or equal to 100uA. In this case, the photoelectric sensor 41 must be able to sense at least 20% of the light transmitted by the first lens group 1. Based on this requirement for the amount of light sensed, the assembly data between the first lens group 1 and the second lens group 3, as well as their respective lens parameters, can be adjusted.

[0042] Based on the technical solution of this disclosure, an electronic device is also provided. This electronic device may include the data transmission device described in any of the foregoing embodiments, thereby enabling signal transmission between functional modules through the data transmission device, reducing the structural design of the circuit board, and improving signal transmission efficiency.
