[0002] An optical drive is a device used to read and write optical discs in a computer. It is commonly found in desktop and portable computers. An optical drive is mainly used to read audio, video, and files from an optical disc, or burn audio, video, and files to an optical disc. It can play audio or video discs, install software, and store large amounts of data.

[0003] However, with the advent of the digital age, many software, data and files can be downloaded and used through the Internet, and CDs are no longer needed. In addition, computers are gradually becoming thinner and more portable, and eliminating optical drives can save computer space more effectively. The development of USB interfaces, Wi-Fi connections and Bluetooth technology has made it more convenient to use mobile storage devices, replacing some of the usage scenarios of optical disks. Therefore, although optical disks have not disappeared, the demand for optical drives has gradually decreased, so that most computers are no longer equipped with optical drives. In order to adapt to changes in computer technology, improve the application efficiency of optical drives, and expand the application scenarios of optical drives, it is necessary to develop an independent external optical drive technology solution to wirelessly transfer data from the optical disk to the mobile terminal.

[0051] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] See also Figure 1 and Figure 2 The embodiment of the present invention provides a method for processing data of an external optical drive capable of remote transmission control, comprising the following steps:

[0053] S1, placing the optical disc carrying data into the optical drive tray 2, irradiating the optical disc track with the laser head movement 6 to read the data, and converting the read optical disc data object with the decoding chip configured by the decoding module 5;

[0054] S2, transmitting the optical disc data object converted by the decoding module 5 to the storage module 7, and dynamically and randomly storing the optical disc data signal through the memory chip 12 configured by the storage module 7;

[0055] S3, sequentially transmitting the optical disc data objects stored in the storage module 7 to the microprocessor 3 for processing, and then transmitting the data processed by the microprocessor 3 to the remote server 24 and the mobile terminal 25 for storage through the wireless communication module 4;

[0056] S4, placing a blank optical disc into the optical drive tray 2, setting the file format of the optical disc to be burned through the mobile terminal 25, and transmitting the optical disc data object to be burned in the local or remote server 24 to the memory chip 12 configured by the storage module 7 through the Wi-Fi antenna of the mobile terminal 25;

[0057] S5 , converting the analog signal of the optical disc data object to be burned in the storage module 7 into a digital signal through the decoding module 5 , and burning the converted digital signal into the blank optical disc in the optical drive tray 2 using the laser head mechanism 6 .

[0058] In this embodiment, a CD / DVD / Blu-ray disc carrying data is placed in the optical drive tray 2, and the movement laser head illuminates different tracks of the disc to read the disc data object, and the disc data object converts the signal through the decoding chip.

[0059] The memory chip 12 dynamically and randomly stores the signal of the optical disc data object, and orderly transmits the stored data to the ARM microprocessor 3 for processing, and then transmits the document data, video and audio in the processed optical disc data object to the remote server 24 and the APP of the mobile terminal 25 for storage through the Wi-Fi single chip connected to the serial communication. When writing is required, a blank optical disc is placed in the optical drive tray 2, the function of the mobile terminal 25 is turned on, and the format file to be burned is transmitted to the optical drive through the Wi-Fi antenna and directly burned on the optical disc.

[0060] In this embodiment, the APP of the mobile terminal 25 can set different optical disc formats (CD / DVD / Blu-ray) and can select the reading and writing functions of the optical disc. During the data writing process, the local files, pictures, videos of the mobile terminal can be called or the files, pictures, and videos of the cloud remote server 24 can be directly obtained for burning. The content is received through the Wi-Fi antenna, microwave despreading and content decompression are performed, and finally restored to an analog content signal. The decoding chip converts the signal into a digital signal, and the digital signal is burned on the optical disc through the laser head movement 6.

[0061] During the data reading process, the CD content signal can also be encoded and compressed, then modulated through a digital microwave channel, and then transmitted through a Wi-Fi antenna, and directly uploaded to the mobile terminal 25 locally or uploaded to a cloud remote server 24 for storage. At the same time, the APP of the mobile terminal 25 can also be used to play the contents of the CD-ROM drive online in real time.

[0062] In this embodiment, during the process of converting the analog signal of the optical disc data object to be recorded in the storage module 7 into a digital signal by the decoding module 5:

[0063] Sampling is performed according to a preset frequency and time interval, and the amplitude range of each sample is divided into several intervals; each block of interval samples is then sampled and processed, and quantized into finite discrete values ​​using a preset filtering algorithm; the quantized digital values ​​are binary encoded to obtain a digital signal.

[0064] For details, see Figure 3 In terms of data signal processing, when the decoding chip converts analog signals into digital signals, it samples at a certain continuous frequency and time interval, divides the amplitude range of each sample into several intervals, and then samples each small interval sample and quantizes it into a limited discrete value using a mean filter algorithm or adaptive quantization technology. The quantized digital value is binary-encoded to obtain a digital signal.

[0065] In a possible embodiment, the preset filtering algorithm adopts mean filtering, and during the mean filtering process:

[0066] Replace each value of the analog signal with the average value of its neighborhood; for a filter window of size m×n, assuming that the pixel values ​​in the window are p1, p2, p3, ..., p(m×n), then the new value P of the central pixel after mean filtering is: P = (p1+p2+p3+...+p(m×n)) / (m×n). See Figure 4 , for a 3X3 continuous array, calculate the average of 9 values ​​to replace the value of the central value.

[0067] In a possible embodiment, the preset filtering algorithm adopts median filtering. During the median filtering process:

[0068] First, assume that there is a one-dimensional digital sequence x[1], x[2], ..., x[m], and the window size of the median filter is m (usually m is an odd number). For each element x[i] in the digital sequence, take the m elements around it, that is, x[i-(m-1) / 2], ..., x[i], ..., x[i+(m-1) / 2], sort these m elements, and finally use the sorted middle value as the output value to replace the original element x[i]. See Figure 5 , the filtering process for a window m of 3X3.

[0069] See also Figure 6 In a possible embodiment, the preset filtering algorithm adopts Gaussian filtering. During the Gaussian filtering process:

[0070] Assume that there is a very small 3x3 grayscale image. Use a 3x3 Gaussian kernel. The standard deviation σ is set according to the requirements. Assume that σ = 1. Calculate the corresponding Gaussian weight and filter the center pixel value 40 to obtain:

[0071] (10*1 / 16+20*2 / 16+15*1 / 16+30*2 / 16+40*4 / 16+25*2 / 16+18*1 / 16+22*2 / 16+16*1 / 16)=24.5625

[0072] Then, the Gaussian weight is calculated for each pixel in the image to complete the processing of the image by Gaussian filtering. In this way, Gaussian filtering smoothes the image according to the spatial position and weight of the pixel, reducing noise.
