Description

Technical Field

[0001] The present invention relates to the technical field of data transmission, and in particular to a method and system for wirelessly receiving and real-time transmitting hard disk data. Background Art

[0002] For a long time, hard drive data transmission relied primarily on wired connection technologies, such as the common USB and SATA interfaces. In offices, people accustomed to using USB cables to connect hard drives to computers to copy files; in server rooms, SATA interfaces ensure data exchange between hard drives and hosts. However, with the passage of time, these traditional wired transmission methods have exposed a series of problems.

[0003] Poor connection convenience: In scenarios where equipment needs to be frequently moved or data transmission needs to be rapidly deployed, the disadvantages of wired connections become apparent. For example, when working outdoors, workers need to drag long cables to transfer data from hard drives to devices in different locations. This is not only inconvenient but also prone to cable entanglement and even damage.

[0004] Limited transmission efficiency: Wired transmission speeds often fail to meet the demands of transferring large amounts of data. For example, in the film and television production industry, editors need to transfer large amounts of high-definition video footage from external hard drives to computers for editing. Using traditional wired interfaces can take hours, severely impacting work progress.

[0005] Compatibility issues are prominent: Different devices have different interface specifications and protocols, which often lead to interface mismatches or driver incompatibilities during actual data transfers. For example, when a user wants to connect a new hard drive to an older computer, data transfer may not be possible due to different interface standards.

[0006] The booming development of wireless communication technologies, such as Wi-Fi, Bluetooth, and 5G, has opened up new avenues for data transmission from hard drives. Wireless transmission, by eliminating the constraints of cables, allows for more flexible data exchange between devices. In a home environment, users can easily wirelessly transfer multimedia files from hard drives to smart TVs for playback. However, wireless transmission is not perfect. Signal stability is a challenge and it is easily affected by obstacles, electromagnetic interference, and other factors, leading to data loss or transmission interruptions. Summary of the Invention

[0014] As a further solution of the present invention: during transmission, the wireless transmission module first constructs a Hamming code data block sequence using the Hamming code data blocks encoded after each data block is transmitted, and then divides the encoded Hamming code data block sequence into a plurality of data transmission packets. The size of the data transmission packet is determined by the bandwidth of the wireless channel, that is, the size of the data transmission packet is smaller than the amount of data transmitted by the channel per unit time.

[0015] As a further solution of the present invention: wherein, the wireless transmission module includes a sending unit arranged at the hard disk end and a receiving unit arranged at the receiving end; Each data transmission packet contains a synchronization code in the header of the data transmission packet, a data transmission packet sequence number, a data transmission packet length, and coded data in the coding sequence; The sending unit is used to transmit the data transmission packet from the hard disk end to the receiving end, and the receiving unit is used to receive the data transmission packet. When receiving the data transmission packet, the clock is first synchronized through the synchronization code, and then the data transmission packet is received. At the same time, the continuity of the data transmission packet sequence number in the data transmission packet header and the correctness of the data transmission packet length are used to preliminarily determine whether the data transmission packet is complete; When the data transmission packet sequence numbers of multiple data transmission packets are not continuous, the data transmission packets are judged to be incomplete; When the data transmission packet lengths of multiple data transmission packets are inconsistent, it is determined that the data transmission packet is incomplete.

Then, the original data bits other than the check bits are extracted from the Hamming code data block, and then the original data bits of all Hamming code data blocks are combined to obtain the recovered binary data sequence.

[0019] Data format standardization: The preprocessing module converts the raw data into a binary format using pre-set conversion rules, so that raw data of different types and formats can be subsequently processed according to a unified standard, which is conducive to the further processing and transmission of data and improves the compatibility and versatility of the system.

[0020] Transmission Verification: During transmission, the wireless transmission module divides the encoded Hamming code data block sequence into several data packets. Each data packet contains information such as a synchronization code, data packet sequence number, and data packet length.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only 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 making any creative efforts shall fall within the scope of protection of the present invention.

[0026] Example 1 See also Figure 1 and Figure 2 As shown, the present invention is a hard disk data wireless receiving and real-time transmission system, comprising: The data extraction module is used to monitor the data changes on the hard disk in real time and extract the relevant original data when new data is generated or data needs to be transmitted; The extracted raw data is organized into the raw data sequence D=[d i ],i=1,2,...n,d i Represents the i-th data unit, n represents the number of data units, and a data unit refers to the attribute information corresponding to the file content, file name, creation time, modification time, and file size; Among them, the hard disk can be a traditional mechanical hard disk or various types of storage devices such as solid-state hard disk. The hard disk data exists in the form of magnetic signals or flash memory storage. For mechanical hard disks, the magnetic head senses the changes in magnetic signals on the disk to read the data; for solid-state hard disks, the electronic characteristics of the flash memory chip are used to read the stored data; The preprocessing module is used to preprocess the original data in the following ways: The original data is uniformly converted into a binary data sequence B=[b j ],j=1,2,…m,b j Represents a binary bit, and m represents the number of binary bits corresponding to the original data in binary format; The data block module is used to block the binary data sequence according to a preset fixed length and obtain multiple data blocks, which are then combined into a data block set and marked as C=[C t ], t=1, 2, ... k, k represents the number of data blocks; Among them, C t =[b （t-1）L+1 ,b （t-1）L+2 , ... b （t）L ], and b （t-1）L+1 Indicates the position of the first element of the t-th data block in the original binary data sequence, b （t-1）L+2 Indicates the position of the second element in the tth data block in the original binary data sequence, b（t）L Indicates the position of the last element of the t-th data block in the original binary data sequence; In this embodiment, when t=1, b （t-1）L+1 (t-1)L+1=(1-1)L+1=1, which means that the first data of the first data block is the first data b1 in the original binary data sequence; when t=2, b （t-1）L+1 In the equation (t-1)L+1=(2-1)L+1=L+1, the first data of the second data block is the data b starting from the first position in the original binary data sequence. L+1 , and so on; The data encoding module is used to encode each data block. The encoding processing method is as follows: It uses Hamming code encoding, which is a coding method that can detect and correct single-bit errors; Step A1: Each data block C t The binary data is marked as C t =[c t，1 ,c t，2 ,……c t，L ], then according to data block C t The length L of the check bits is used to determine the number of check bits to be added when generating the Hamming code, where the number of check bits to be added satisfies 2 r ≥L+r+1, where r represents the number of check digits added; Step A2: According to the check bit rule of Hamming code, s-1 , determine the position of the check bit, and then pass the corresponding position 2 in the data block s-1 The multiple bits are XORed to obtain the value of each check bit, and then the Hamming code data block H is generated according to the number of check bits added r and the value of each check bit. t =[h t，1 ,h t，2 ,……h t，L+r ]; Among them, s represents the sequence number of the check bit, 2 s-1 Used to determine the position and number of check bits in Hamming code, 2 s-1 is the position of the sth check digit; The value of each check digit is calculated as follows:

[0027] in, is the XOR operator, 2 s-1 is the position of the sth check bit, and s=1, 2, ... r, the values ​​of the other non-check bits and the Hamming code bits of the original data block C t The bits in are the same; For example: Assume that the original data block is C t =[1, 0, 1, 1, 0, 1, 0], where the original data block length L = 7, and r = 4 is calculated, which means that 4 check bits need to be added; The first check digit is 2 0 =1, the second check digit is 2 1 =2, the third check digit is 2 2 =4, the fourth check digit is 2 3 =8, where the original data block is only 7 bits long, so the fourth check bit is actually after the 7th bit; The value of the first check bit position is XORed by the bits at positions 1, 2, 4, and 8 corresponding to the multiple position, that is, ; in, It is the XOR operator symbol, that is, when the two binary bits are the same, that is, both binary bits are 0 or both binary bits are 1, the result of the XOR operation is 0; when the two binary bits are different, that is, one of the two binary bits is 0 and the other is 1, the result of the XOR operation is 1; The value of the second check bit position is XORed by the bits at positions 2, 4, and 6 corresponding to the multiple positions, that is, ; The value of the third check bit position is XORed by the bits at positions 4 and 8 corresponding to the multiple position, that is, ; The value of the fourth check bit position is XORed by the bits at positions 2, 4, and 6 corresponding to the multiple position, that is, ; That is, the generated Hamming code data block is H t =[0,0,1,1,0,1,0,0]; A wireless transmission module is used to transmit Hamming code data blocks from the hard disk end to the receiving end; During transmission, the wireless transmission module divides the encoded Hamming code data block sequence into several data transmission packets. The size of the data transmission packet is determined by the bandwidth of the wireless channel. The size of the data transmission packet is smaller than the amount of data transmitted by the channel per unit time. Wherein, the Hamming code data block sequence is composed of the Hamming code data blocks after encoding each data block; In this embodiment, for example, for a wireless channel with a bandwidth of 10 Mbps, to ensure real-time and smooth data transmission, the size of the data transmission packet needs to be determined based on the transmission rate and the expected transmission time. Assuming that a data transmission packet is expected to be transmitted within 1 millisecond, the size of the data transmission packet cannot exceed approximately 10 kb (10 Mbps × 1 ms = 10 kb). If the data transmission packet is too large, it may increase transmission delay and affect real-time performance. If the data transmission packet is too small, the number of data transmission packets will increase, thereby increasing additional overhead such as packet headers and reducing transmission efficiency. The data decoding module is used to perform Hamming code decoding on the received data transmission packet to obtain the recovered binary data sequence. The Hamming code decoding method is as follows: Reassemble multiple data transmission packets according to the data transmission packet sequence number, and obtain the received Hamming code data block, and mark it as H1 t =[h1 t，1 ,h1 t，2 ,……h1 t，L+r ]; Determine the position of the check bit in the received Hamming code data block according to the check bit rule during the encoding processing of the data encoding module; Then, the checksum of the received Hamming code data block is calculated according to the calculation method of the check bit during the encoding process of the data encoding module; The checksum calculated from the Hamming code data block is then compared with the check bit in the received Hamming code: If the calculated checksum is consistent with the check bit in the received Hamming code, it means that the received Hamming code data block has no errors. Then, the original data bits other than the check bit are extracted from the Hamming code data block. After that, the original data bits of all the Hamming code data blocks are combined to obtain the recovered binary data sequence. If the calculated checksum matches the check bit in the received Hamming code, it means that the received Hamming code data block has an error. Once the position of the error bit is determined, the bit can be corrected. If the value of the error bit is 1, it is changed to 0; if the value of the error bit is 0, it is changed to 1; For example, if the error bit is determined to be at bit 4 by the above method, and the value of bit 4 in the received Hamming code data block is 0, then change it to 1; After correcting the error, remove the check bits in the Hamming code and extract the original data bits; that is, take the bits that are not check bits from the Hamming code data block and combine them in the order of the original data to obtain the recovered original data; Hamming code also has error correction capabilities. By determining the number and position of check bits and calculating the check bit values ​​according to specific rules to generate a Hamming code data block, even if a small number of errors occur during data transmission, the errors can be detected and corrected through the decoding process, thereby improving the accuracy and reliability of data transmission. Finally, the binary data sequence is converted into a format according to the conversion rules preset by the preprocessing module, and the binary format data is restored to the format of the original data to obtain the final received data.

[0028] This embodiment can monitor the changes in hard disk data in real time, extract newly generated or transmitted data in a timely and accurate manner, ensure the timeliness and comprehensiveness of data acquisition, and can adapt to various types of hard disks, including traditional mechanical hard disks and solid-state hard disks. By uniformly converting the original data into a binary format, a standardized foundation is laid for subsequent data processing, and the consistency and compatibility of data processing are improved. Binary data sequences are divided into blocks of fixed length to make data processing more organized and efficient, which facilitates subsequent encoding and transmission operations. Using Hamming code encoding can detect and correct single-bit errors, enhance the reliability of data transmission, and reduce the risk of data errors during transmission. The data transmission packet size is determined based on the wireless channel bandwidth, taking into account both real-time and transmission efficiency, avoiding delays caused by excessively large data transmission packets or additional overhead caused by too small data transmission packets. By reorganizing data transmission packets, checking and comparing, etc., the original data can be accurately restored to ensure the accuracy and integrity of the received data.

[0029] Example 2 See also Figure 1 and Figure 2 As shown, as the second embodiment of the present invention, when the present application is specifically implemented, compared with the first embodiment, the technical solution of this embodiment is different from that of the first embodiment only in that, in this embodiment, each data transmission packet includes a synchronization code in the header of the data transmission packet, a data transmission packet sequence number, a data transmission packet length, and the encoded data in the encoding sequence; And mark the format of each data transmission packet as P0 q =[P1 q ,P2 q ,P3 q ,P4 q ], q = 1, 2, ... c, c represents the number of data transmission packets, where P1 is the synchronization code, which is used by the receiving end to synchronize the receiving clock; P2 is the data transmission packet sequence number, which is used by the receiving end to sort the data transmission packets and detect loss; P3 is the data transmission packet length; P4 is the coded data in the data transmission packet; In this embodiment, the wireless transmission module adopts Bluetooth 5.0 technology as a wireless communication method, and the wireless transmission module includes a sending unit provided at the hard disk end and a receiving unit provided at the receiving end; The sending unit is used to transmit the data transmission packet from the hard disk end to the receiving end, and the receiving unit is used to receive the data transmission packet. When receiving the data transmission packet, the clock is first synchronized through the synchronization code, and then the data transmission packet is received. At the same time, the continuity of the data transmission packet sequence number in the data transmission packet header and the correctness of the data transmission packet length are used to preliminarily determine whether the data transmission packet is complete; When the data transmission packet sequence numbers of multiple data transmission packets are not continuous, the data transmission packets are judged to be incomplete; When the data transmission packet lengths of multiple data transmission packets are inconsistent, it is determined that the data transmission packet is incomplete.

[0030] This embodiment sets information such as a synchronization code, a data transmission packet sequence number, and a data transmission packet length in the data transmission packet header to provide the receiving end with more auxiliary information and ensure the accuracy and integrity of data reception. The synchronization code is used to synchronize the receiving clock at the receiving end, ensuring the correct timing of data reception and improving the stability of data transmission. By using the continuity of the data transmission packet sequence number and the correctness of the data transmission packet length, it is possible to quickly determine whether the data transmission packet is complete, facilitating the timely detection and resolution of transmission problems. Using Bluetooth 5.0 technology, it provides a mature and reliable wireless communication solution with advantages such as low power consumption and high transmission rate to meet practical application needs.
