[0071] See Figure 6 and Figure 7 , an external optical drive data processing method capable of remote transmission control provided by an embodiment of the present utility model includes the following steps:

[0072] S1. Place the optical disc carrying data into the optical drive tray 2, irradiate the optical disc track through the laser head module 6 to read the data, and use the decoding chip configured by the decoding module 5 to convert the read optical disc data object;

[0073] S2. Transmit the optical disc data object converted by the decoding module 5 to the storage module 7, and perform dynamic random storage on the optical disc data signal through the memory chip 12 configured by the storage module 7;

[0074] S3. Sequentially transmit the optical disc data object stored in the storage module 7 to the microprocessor 3 for processing, and then transmit the data processed by the microprocessor 3 to the remote server 24 and the mobile terminal 25 through the wireless communication module 4 for storage;

[0075] S4. Place a blank optical disc into the optical drive tray 2, set the optical disc file format to be burned through the mobile terminal 25, and transmit the optical disc data object in the local or remote server 24 to be burned to the memory chip 12 configured by the storage module 7 through the Wi-Fi antenna of the mobile terminal 25;

[0076] S5. Convert 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 use the laser head module 6 to burn the converted digital signal onto the blank optical disc in the optical drive tray 2.

[0077] In this embodiment, a CD / DVD / Blu-ray disc carrying data is placed in the optical drive tray 2, and the optical head of the movement irradiates different tracks of the disc to read the disc data object, and the disc data object converts the signal through a decoding chip.

[0078] Among them, the memory chip 12 dynamically stores the signal of the disc data object, and orderly transmits the stored data to the ARM microprocessor 3 for processing. Then, through the Wi-Fi single chip connected to the serial port communication, the document data, video, and audio in the processed disc data object can be transmitted to the remote server 24 and the APP of the mobile terminal 25 for storage. When writing is required, a blank 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 disc.

[0079] In this embodiment, the APP of the mobile terminal 25 can set different disc formats (CD / DVD / Blu-ray), and can select the read and write functions of the disc. During the data writing process, the local files, pictures, videos of the mobile terminal can be called, or the files, pictures, videos of the cloud remote server 24 can be directly obtained for burning. The content receives signals through the Wi-Fi antenna, performs microwave despreading and content decompression, and finally restores to an analog content signal. The decoding chip converts the signal into a digital signal, and the digital signal is burned on the disc through the optical head movement 6.

[0080] Among them, during the data reading process, the disc content signal can also be encoded and compressed, then modulated through a digital microwave channel, and then transmitted through the Wi-Fi antenna, directly uploaded to the local of the mobile terminal 25 or uploaded to the cloud remote server 24 for storage. At the same time, the APP of the mobile terminal 25 can also be used to play the content in the optical drive online in real time.

[0081] In this embodiment, during the process of converting the analog signal of the disc data object to be burned in the storage module 7 into a digital signal by the decoding module 5:

[0082] Sampling is performed according to a preset frequency and time interval, and the amplitude range of each sampling sample is divided into several intervals; then the interval samples of each block are sampled, and a preset filtering algorithm is used to quantize them into finite discrete values; the quantized digital values are binary-coded to obtain a digital signal.

[0083] Specifically, see Figure 8, in terms of data signal processing, during the process of the decoding chip converting analog signals into digital signals, sampling is performed within a certain continuous frequency and time interval. The amplitude range of each sample is divided into several intervals, and then the interval samples of each small piece are sampled and processed, and the mean filtering algorithm or adaptive quantization technology is used to quantize them into a limited number of discrete values. Binary encoding the quantized digital values can obtain digital signals.

[0084] In a possible embodiment, the preset filtering algorithm adopts mean filtering. During the mean filtering process:

[0085] Each value of the analog signal is replaced with the average value of its neighboring values; for a filtering window of size m×n, assuming the pixel values within the window are p1, p2, p3,..., p(m×n) respectively, then the new value P of the central pixel after mean filtering is: P = (p1 + p2 + p3 +... + p(m×n)) / (m×n). See Figure 9 , for a 3X3 continuous array, calculate the average value of 9 values to replace the value of the central value.

[0086] In a possible embodiment, the preset filtering algorithm adopts median filtering. During the median filtering process:

[0087] First, assume there is a one-dimensional digital sequence x[1], x[2],..., x[m], the window size of median filtering is m (usually m is an odd number). For each element x[i] in the digital sequence, take its surrounding m elements, that is, x[i - (m - 1) / 2],..., x[i],..., x[i + (m - 1) / 2], sort these m elements, and finally use the middle value after sorting as the output value to replace the original element x[i]. See Figure 10 , for the process of filtering with a window m of 3X3.

[0088] See Figure 11 , in a possible embodiment, the preset filtering algorithm adopts Gaussian filtering. During the Gaussian filtering process:

[0089] Assume there is a very small 3x3 grayscale image, use a 3x3 Gaussian kernel, the standard deviation σ is set according to requirements, assume σ = 1, calculate the corresponding Gaussian weights, and perform filtering processing on the central pixel value 40 to get:

[0090] (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

[0091] Then, calculate the Gaussian weights for each pixel in the image to complete the processing of the image by Gaussian filtering. In this way, Gaussian filtering smooths the image according to the spatial position and weights of the pixels, reducing noise.
