Description

Technical Field

[0001] The invention belongs to the technical field of data processing, and in particular relates to a method and a device for creating a file of torpedo internal measurement data. Background Art

[0002] A torpedo is a highly efficient underwater self-propelled guided weapon used to attack submarines, surface ships and other underwater targets. It has the characteristics of good concealment and strong explosive power, and is one of the navy's main attack weapons.

[0003] In tasks such as torpedo scientific research tests, equipment delivery tests, and actual combat training tests for troops, the external test data of the underwater array in the test waters and the internal test data recorded autonomously by the torpedo are collected, which is the main basis for comprehensive evaluation of the completion effect of the test tasks. The internal test data of the torpedo is usually stored in the form of data files on the data storage chip inside the torpedo. In order to facilitate data management, a method of digital difference naming is adopted based on real-time Beijing time (year, month, day, hour, minute, second).

[0004] The method of naming the internal test data file using Beijing time requires the use of hardware resources such as RTC clock chips. These chips have built-in battery chips.

However, for products that are stored in inventory for a long time, the RTC chip battery may be over-discharged and cause functional failure, resulting in the risk of being unable to create an internal test data folder. Therefore, it is urgent to design a low-cost, high-reliability data file creation method that does not rely on clock chip hardware resources to realize torpedo internal test data recording. Therefore, how to provide a file creation method for torpedo internal test data has become a technical problem that urgently needs to be solved in this field. Summary of the invention

[0060] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all 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.

[0061] The present application discloses a method for creating a file of torpedo internal test data, including a timestamp parameter setting instruction, parameter validity judgment, parameter writing file, parameter file reading, data file management, and data file creation technology;

[0062] Reference Figure 1 , shows a flowchart of the steps of a method for creating a file of torpedo internal test data of the present application, which method can be applied to electronic devices, wherein the method specifically may include the following steps:

[0063] S101, obtaining preset timestamp parameters;

[0064] S102, determining a first data file name corresponding to a preset timestamp parameter according to the preset timestamp parameter;

[0065] S103, comparing the first data file name with the second data file name; the second data file name is the file name of the latest stored time;

[0066] S104: Determine the file corresponding to the latest data file name between the first data file name and the second data file name as the target internal test file.

[0067] When creating a torpedo data file, the latest data file stored on the disk and the data file created by the timestamp file are compared, and a torpedo internal test data folder is created based on the newer data file name.

[0068] For example, when creating a torpedo data file, the corresponding data file name recDir is calculated based on the Beijing time timestamp parameter in Date_TimeRunPara, and the size of recDir and last_dataFile is compared. The larger value is the new file name. If the data file name recDir created by the Beijing time timestamp parameter is newer, the mkdir(recDir) function is used to create a torpedo internal test data folder; if last_dataFile is newer, last_dataFile is cumulatively added by 1, and the sexagesimal system of hours, minutes and seconds is used to handle the carry problem, and the newly generated folder name is assigned to recDir, and then the mkdir(recDir) function is used to create a torpedo internal test data folder.

[0069] Another embodiment of the present application further supplements the method for creating a file for torpedo internal measurement data provided in the above embodiment.

[0070] Optionally, determining the file corresponding to the latest data file name between the first data file name and the second data file name as the target internal test file includes:

[0071] If the time of the first data file name is newer, the mkdir(recDir) function is used to create the first torpedo internal test data file, and the first torpedo internal test data file is used as the target internal test file;

[0072] If the time of the second data file name is newer, a sexagesimal processing and carry algorithm of the hours, minutes and seconds is adopted to generate a second torpedo internal test data file, and the second torpedo internal test data file is used as the target internal test file.

[0073] Optionally, the preset timestamp parameter is obtained in the following manner:

[0074] In the torpedo firing preparation, the time stamp parameter online binding information command is received through the CAN bus;

[0075] Determine whether the data segment of the online binding information instruction of the timestamp parameter meets the logical requirements of the time and date;

[0076] If the timestamp parameter meets the logical requirement of time, the timestamp parameter is determined as the preset timestamp parameter.

[0077] During the preparation for torpedo firing, Beijing time parameters are set and stored in the parameter file. During actual navigation, timestamp parameters are read from the parameter file and participate in the creation process of the internal test data folder.

[0078] Optionally, if the timestamp parameter meets the logical requirement of time, determining the timestamp parameter as a preset timestamp parameter includes:

[0079] Perform validity judgment on the data segment of the online binding information instruction of the timestamp parameter;

[0080] If the logical requirement that the month value is not greater than 12 and the date value is not greater than 31 is met, the timestamp parameter in the timestamp parameter online binding information instruction is determined to be a valid parameter, and the timestamp parameter is determined to be a preset timestamp parameter.

[0081] After the torpedo launch internal test function is started, the validity of the 8-byte DATA data segment received from the combat self-test command is judged, and the timestamp file is written only when the parameters are valid.

[0082] In the preparation before torpedo firing, a portable setting instrument and other equipment are used to send parameter online binding information through the combat self-test command (ID: 0x01FE0100) of the CAN bus. After the torpedo receives the combat self-test command, the validity of its 8-byte DATA data segment is judged. If the logical conditions such as the month value is not greater than 12 and the date value is not greater than 31 are met, the 8-byte DATA data segment is used as the Beijing time timestamp parameter and written into the Beijing time timestamp file Date_Time.bin on the non-volatile memory of the torpedo. Otherwise, the write operation is not performed.

[0083] Optionally, the method further comprises:

[0084] After the torpedo launch internal test function is started, open the file with preset timestamp parameters;

[0085] If error is opened, the default parameters are used.

[0086] After the torpedo launch internal test function is started, when the disk Beijing time timestamp parameter file is opened successfully, the read parameters will be stored in the cache variable, otherwise the parameter cache variable will be assigned a default value.

[0087] After the torpedo launch internal test function is started, the Beijing time timestamp file Date_Time.bin is opened. If the file is opened successfully, the file content is read and stored in the program cache variable Date_TimeRunPara. If the opening fails, the default value is assigned to Date_TimeRunPara. In the quantity management of the data folders that already exist on the data storage, the digital data file names are traversed and the size of the data file name strings is compared, that is, the smallest string is the oldest file, and the largest string is the latest file. The oldest data file is deleted, and the latest data file name is stored in the variable last_dataFile.

[0088] Optionally, the method further comprises:

[0089] The number of existing data folders on the data storage device is managed, the oldest data folder is deleted, and the current latest data folder name is screened out, and the current latest data file name is determined as the second data file name.

[0090] When managing the number of data folders that already exist on the data storage device, the oldest file is deleted and the latest data file is recorded.

[0091] Optionally, the number of data folders already existing on the data storage device is managed, and the oldest data folder is deleted, including:

[0092] By traversing the digital data file names, the string sizes of the data file names are compared;

[0093] Identify the smallest string as the oldest file, the largest string as the newest file, delete the oldest data file, and store the newest data file name in a variable.

[0094] In the quantity management of the data folders that already exist on the data storage device, by traversing the digital data file names and using the method of comparing the data file name string size, the oldest data file is deleted and the latest data file name is stored in the variable last_dataFile.

[0095] In tasks such as torpedo scientific research tests, equipment delivery tests, and troop actual combat training tests, the Beijing time timestamp parameter setting including the date and time is completed before the torpedo is fired, and the valid setting parameters are stored in the non-volatile memory in the form of a file. After the torpedo launch internal test function is started, first open the Beijing time timestamp parameter file ( Figure 2 ), if an error occurs when opening, use the default parameters; secondly, manage the number of data folders that already exist on the data storage device, delete the oldest data folder, and filter out the current latest data folder name; finally, if the Beijing time stamp parameter is newer than the current latest data folder name filtered out, create an internal test data file with the Beijing time stamp parameter, otherwise, create a new data folder by accumulating the count of the latest folder name on the data storage device.

[0096] The present invention does not rely on the traditional RTC clock chip hardware and does not add new hardware resources. It adopts a brand-new software design method to realize the torpedo internal test data file creation function, reduces the development and production costs of the torpedo, and completely solves the risk of the clock chip built-in battery possibly being over-discharged and causing functional failure, and realizes the online loop recording function of the digital difference naming test data file ( Figure 3 ), avoiding data overwriting and improving the offline management efficiency of massive actual flight test data.

[0097] In order to achieve the above object, the present invention adopts the following technical solution:

[0098] In the preparation before torpedo firing, complete the Beijing time timestamp parameter setting including date and time, and store the valid setting parameters in the non-volatile memory in the form of a file. After the torpedo launch internal test function is started, first open the Beijing time timestamp parameter file. If an error occurs during opening, use the default parameters; secondly, manage the number of data folders that already exist on the data storage device, delete the oldest data folder, and filter out the latest data folder name; finally, if the Beijing time timestamp parameter filters out the latest data folder name update, create an internal test data file with the Beijing time timestamp parameter, otherwise, create a new data folder by accumulating the latest folder name on the data storage device.

[0099] The embodiment of the present application utilizes the setting parameter file content stored in the torpedo pre-fire preparation, combined with the data file status stored in the torpedo data storage device, to design a parameterized creation method for the internal test data file, thereby realizing a torpedo internal test data file creation function that does not rely on the RTC clock chip hardware.

[0103] 3) The embodiment of the present application adopts a method of digitally differentially naming the internal test data files based on Beijing time, which realizes online circular recording of test data files, avoids data overwriting, reduces special operations for data erasure, and can improve the offline management efficiency of massive actual flight test data. It is a brand-new design method and idea.
