The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0051] Embodiment 1

[0052] like Figure 1 As shown, the present invention proposes a method for quickly distinguishing the storage mode of a SEGY file, comprising the following steps:

[0053] S1. Acquire a seismic file to be parsed, identify header information of the seismic file to be parsed, set a file operation mode of the seismic file to be parsed, and construct a calling program of the seismic file to be parsed according to the header information and the file operation mode.

[0054] The embodiment of the present invention can determine the file structure of the seismic file to be parsed by identifying the header information of the seismic file to be parsed, and then set the file access method according to the file structure. The header information refers to the basic description and parameter settings of the file, such as data format, sampling rate, number of sampling points, data compression method, etc.

[0055] Optionally, the header information of the seismic file to be parsed is identified by reading the metadata of the seismic file to be parsed using a metadata reading code generated by Java language.

[0056] Furthermore, the embodiment of the present invention can provide a basic operation basis for the subsequent operation mode required for the seismic file to be parsed by setting the file operation mode of the seismic file to be parsed, and can also accurately perform operations such as reading and writing on the file.

[0057] Optionally, the file operation mode of setting the seismic file to be parsed is generated by a file operation function generated by Python language.

[0058] The embodiment of the present invention constructs a calling program for the seismic file to be parsed according to the header information and the file operation mode, so that the file operation to be performed can be programmed and then the file operation can be performed automatically, wherein the calling program refers to a function generated by languages ​​such as Java and Python to achieve a certain purpose or complete a certain task.

[0059] As an embodiment of the present invention, the calling program of the seismic file to be parsed is constructed according to the header information and the file operation mode, including: constructing a calling text box of the seismic file to be parsed, converting the header information into parameters to be operated, converting the file operation mode into operation instruction parameters, inputting the parameters to be operated and the operation instruction parameters into the calling text box, and activating the calling text box to obtain the calling program of the seismic file to be parsed.

[0060] The calling text box refers to the basic framework of the operating program, and the parameters refer to the basic codes that can be read and used by the program.

[0061] Optionally, the calling text box of the seismic file to be parsed is generated by Java, and the parameters to be operated and the operation instruction parameters are converted by binary code.

[0062] S2. Using the calling program, release the communication connector to the kernel space of the seismic file to be parsed to obtain the connection space, and using the connection space to perform management authorization on the seismic file to be parsed to obtain the management file.

[0063] The embodiment of the present invention utilizes the calling program to release a communication connector to the kernel space of the seismic file to be parsed, and obtains a connection space that can connect the operating system and the application to provide operating resources for the operating system. The kernel space refers to a part of the operating system used to execute kernel code and process system resources, and the communication connector refers to special characters, strings, marks, etc. used to establish and maintain communication connections.

[0064] As an embodiment of the present invention, the method of using the calling program to release a communication connector to the kernel space of the seismic file to be parsed to obtain a connection space includes: constructing a synchronous channel between the calling program and the kernel space, generating a communication connector of the calling program, transmitting the communication connector to the kernel space through the synchronous channel, and performing credit authentication on the communication transmission symbol in the kernel space to obtain a connection space. The synchronous channel refers to a channel that keeps a constant time for data transmission and has a data adjustment function, and the credit authentication refers to authorization of data communication.

[0065] Optionally, the synchronous channel between the calling program and the kernel space is constructed through a pss channel, and the communication connector of the calling program is generated through a script generated by java language.

[0066] Furthermore, the embodiment of the present invention uses the connection space to manage and authorize the seismic file to be parsed, and the management file can obtain the file viewing authority, and then all the information of the seismic file to be parsed can be queried.

[0067] As an embodiment of the present invention, the use of the connection space to manage and authorize the seismic file to be parsed to obtain a management file includes: formulating a communication process and data exchange rules between the seismic file to be parsed and the connection space, and generating a data transmission protocol between the connection space and the seismic file to be parsed, constructing a communication protocol between the connection space and the seismic file to be parsed based on the communication process, the data exchange rules and the data transmission protocol, and authorizing the seismic file to be parsed based on the communication protocol to obtain a management file.

[0068] Among them, the communication process refers to the method of transmitting and receiving data, the data exchange rule is the format of the file directly received or transmitted, the data transmission protocol refers to a mechanism provided by a layer of the data link for data transmission, and the communication protocol refers to a security protocol for data transmission to ensure the security of data transmission.

[0069] Optionally, the communication process and data exchange rules between the seismic file to be parsed and the connection space are generated by Python language according to preset communication protocols and data exchange rules, and the data transmission protocol between the connection space and the seismic file to be parsed is generated by TCP communication protocol, and the communication protocol is generated by HTTP application protocol.

[0070] S3. Query the file descriptor of the management file, use the file descriptor to locate the binary character of the management file, obtain a character return pointer, parse the character information of the character return pointer, and obtain the storage location of the management file.

[0071] In the embodiment of the present invention, the special characters describing the file can be obtained by querying the file descriptor of the management file, and then the required file can be queried. The file descriptor refers to an integer value used to identify and operate a file or an input / output device. In UNIX-like systems, including Linux and MacOS, each open file or device is assigned a unique file descriptor.

[0072] Optionally, the file descriptor of the management file is queried through a script generated by JAVA language.

[0073] Furthermore, the embodiment of the present invention uses the file descriptor to locate the binary character of the management file, and obtains the character return pointer, so as to query the specific location of the track data of the management file in the storage system, and then understand the encoding information of the management file.

[0074] As an embodiment of the present invention, the method of locating the binary character of the management file by using the file descriptor to obtain a character return pointer includes: constructing a character query function of the file descriptor, and calculating the return value of the character query function by using the following formula:

[0075]

[0076] Among them, G represents the return value, n represents the number of file descriptors, and n i Represents the i-th descriptor of the file descriptor, ∈(n i ) represents the return function of the file descriptor, θ represents the character query function, m j represents the jth character of a binary character, ρ represents the character encoding function, m represents the number of binary characters,

[0077] The binary character of the management file is located according to the return value to obtain a character return pointer.

[0078] Optionally, the character query function is constructed using Python language.

[0079] The embodiment of the present invention can obtain the storage location of the management file by parsing the character information of the character return pointer to understand the storage information of the management file, and then query the storage node of the file information to be queried according to the storage information. The character return pointer refers to the information feedback character, that is, the task feedback information returned by the system when a certain task is executed.

[0080] As an embodiment of the present invention, parsing the character information of the character return pointer to obtain the storage location of the management file includes: identifying the file attribute characters in the character return pointer, decoding the file attribute characters to obtain the file attributes, querying the file management interface of the management file according to the file attributes, querying the storage address number of the management file according to the file management interface, and obtaining the storage location of the management file according to the storage address number.

[0081] The file attribute characters refer to characters describing file attributes, such as file format, creation time, file path, etc.; the storage address number refers to the IP address number.

[0082] The optional file attribute characters are identified by querying the character source code of the character return pointer, the file attribute characters are decoded, the file attributes are obtained by generating a character decoding script in java to identify, and the storage IP of the management file is queried by the ipconfig tool generated in C language.

[0083] S4, retrieving the fixed bytes in the storage location, calculating the number of the fixed bytes, and determining the storage mode of the seismic file to be parsed according to the number of bytes.

[0084] In the embodiment of the present invention, the fixed bytes in the storage location can be retrieved as a prelude for the subsequent byte number calculation, because the fixed bytes of the SEGY file are special, and thus querying the fixed bytes of the SEGY file is of great significance for analyzing the storage method of the SEGY file. The byte refers to a basic unit for recording information in a computer system, and the fixed bytes are preset 3225-3226 bytes.

[0085] Optionally, the fixed bytes in the storage location are queried by generating a byte retrieval script using the Python language. Since the bytes are stored in a fixed order of 0, 1, 2, by inputting byte parameters in the byte retrieval script, the script automatically locates the set byte parameter point to obtain the fixed bytes.

[0086] Furthermore, the embodiment of the present invention can determine the storage mode (big-endian mode, little-endian mode) of the seismic file to be parsed by calculating the number of bytes of the fixed bytes.

[0087] As an embodiment of the present invention, the calculation of the number of bytes of the fixed bytes includes: identifying the encoding tool of the fixed bytes, and querying the encoding rules of the encoding tool, obtaining the number of encoded characters of the fixed bytes according to the encoding rules, and calculating the number of bytes of the fixed bytes according to the number of encoded characters.

[0088] Among them, the encoding tool refers to a tool for converting data into code, such as tensorflow, pytorch, keras, etc., and the encoding rule refers to the encoding method, such as each character in ASCII encoding occupies 1 byte, while Chinese characters in UTF-8 encoding occupy 3 bytes.

[0089] Optionally, the fixed-byte encoding tool is identified by querying the fixed-byte file format. It should be noted that each encoding tool has fixed encoding rules. The encoding rules can be understood by obtaining the encoding tool. The number of encoded characters of the fixed byte is calculated by the encoded characters. For example, one character in ASCII encoding means that the fixed byte contains one byte.

[0090] Furthermore, in an embodiment of the present invention, the storage method of the seismic file to be parsed is determined based on the number of bytes. When the number of bytes is an integer multiple of 1 to 8, it is stored in little endian format, otherwise it is stored in big endian format. The storage method of the seismic file to be parsed can be understood based on the rule.

[0091] Embodiment 2

[0092] In order to understand the present invention more clearly, a second embodiment is used below to further explain the situation in which the number of bytes of the fixed bytes in the embodiment of the present invention is calculated.

[0093] The present invention can pave the way for subsequent byte number calculations based on the header information and the calculation of the number of bytes of the fixed bytes, because the fixed bytes of the SEGY file are special, and thus querying the fixed bytes of the SEGY file is of great significance for analyzing the storage method of the SEGY file. Among them, the byte refers to a basic unit for recording information in a computer system, and the fixed bytes are preset 3225-3226 bytes.

[0094] As an embodiment of the present invention, the calculation of the number of bytes of the fixed bytes includes: identifying the encoding tool of the fixed bytes, and querying the encoding rules of the encoding tool, obtaining the number of encoded characters of the fixed bytes according to the encoding rules, and calculating the number of bytes of the fixed bytes according to the number of encoded characters.

[0095] Among them, the encoding tool refers to a tool for converting data into code, such as tensorflow, pytorch, keras, etc., and the encoding rule refers to the encoding method, such as each character in ASCII encoding occupies 1 byte, while Chinese characters in UTF-8 encoding occupy 3 bytes.

[0096] Optionally, the fixed-byte encoding tool is identified by querying the fixed-byte file format. It should be noted that each encoding tool has fixed encoding rules. The encoding rules can be understood by obtaining the encoding tool. The number of encoded characters of the fixed byte is calculated by the encoded characters. For example, one character in ASCII encoding means that the fixed byte contains one byte.

[0097] Furthermore, in another optional embodiment of the present invention, the step of calculating the number of bytes of the fixed bytes according to the number of coded characters includes:

[0098] The number of bytes of the fixed bytes is calculated using the following formula:

[0099]

[0100] Among them, m represents the number of fixed bytes, n represents the number of coded characters, k i represents the i-th byte in the fixed bytes, and ε represents the encoding rule function.

[0101] The encoding rule function refers to a function constructed according to the encoding rule. For example, one character corresponds to one byte and can be expressed as a=b, and one character corresponds to three bytes and can be expressed as a=3b, where a represents the number of characters and b represents the number of bytes.
