Description
Technical Field
The invention relates to the technical field of logging data transmission, in particular to a breakpoint continuous loading method for downloading acoustic data files of a storage type logging.
Background
At present, the application of storage type logging is more and more widespread, after logging is completed, data measured by an instrument in underground work is required to be transmitted to a PC, and then logging curves which can be analyzed and interpreted by professionals can be obtained after the logging platform loads the data.
The acoustic instrument is a common instrument in the storage type logging instrument, data generated by the acoustic instrument is stored in an acoustic storage plate of the instrument in the logging process, and the recording data generated by the acoustic instrument is extremely large due to the fact that the acquisition time is long and the acquisition sample points are more, and the transmission speed of the acoustic instrument is reduced due to the limitation of hardware equipment and a transmission protocol. In the long-time transmission process, the probability of file transmission failure is increased due to accidents such as unstable line connection, software running, circuit disconnection and the like. When the transmission fails, the whole file needs to be downloaded again, so that time is wasted. Therefore, a product supporting breakpoint continuous transmission needs to be designed to realize uploading of large files, and the transmission speed of data is increased to save time, so that the large data files can be uploaded efficiently and quickly.
The breakpoint freewheel is a common function on PC application software, and if uploading or downloading is interrupted due to unexpected reasons, the next uploading or downloading must be continued from the interruption position, namely the breakpoint position to complete the incomplete operation.
The breakpoint continuous loading is not applied to various related platform software in the logging field. The breakpoint freewheel on daily PC application software is mostly based on the HTTP protocol, is the most widely applied network transmission protocol, and is suitable for daily life. The logging instrument does not follow the HTTP protocol, so that a communication protocol adapting to the requirements needs to be formulated according to the instrument, and the customized breakpoint continuous loading is completed through the operation of issuing a command and a byte stream.
The implementation of breakpoint reloads already existing at the logging platform at the present stage is not the same. The downloading position of the file is saved by setting related variables in the program while downloading the file, and when interruption and reconnection occur, the value of the variable is sent to an instrument to continue transmission. However, the method has a certain limitation that the continuous loading can be realized only under the condition that the software program is in normal operation, and when a circuit is disconnected, a PC is abnormally shut down or logging platform software is accidentally shut down, a constant recorded after the logging platform software is opened again is still initialized, and the recorded and transmitted information also disappears.
For improvement of the method, a configuration file can be newly established, and the variable of the stored information is written into the file so that the configuration file can be read after the platform software is closed and restarted accidentally, and thus the initialized variable is assigned. However, the improved method increases the read-write operation on the file, increases the occupation of system resources, and may slow down the software processing speed and even cause program running. This requires a more rational breakpoint continuous method to be developed and designed.
Disclosure of Invention

step 2: the industrial personal computer starts to determine an acoustic wave file to be downloaded, detects whether the acoustic wave file exists in an information area of a storage board of the acoustic wave instrument, and when the existence of the acoustic wave file is detected, the industrial personal computer opens the acoustic wave file and acquires the length of the acoustic wave file;
step 3: the industrial personal computer detects the sound wave file before downloading to judge whether the downloading is primary downloading or secondary downloading, when the industrial personal computer judges that the downloaded sound wave file is secondary downloading, the industrial personal computer reads the breakpoint position of the downloaded sound wave file when the downloading is primary downloading, and determines the initial storage block number again through calculation, and the sound wave information stored by the sound wave instrument storage board is sent to the industrial personal computer;
step 4: when the secondary downloading starts, the industrial control computer firstly opens the downloaded part of the sound wave file to acquire the byte number of the downloaded file, receives the rest sound wave file and starts writing data from the breakpoint;
step 5: when the sound wave file is transmitted, the transmission flow is closed, all variables are initialized, and occupied resources are released.
Further, when unexpected interruption occurs in the process of receiving the downloading of the data stream by the logging platform software, the industrial control computer saves the acoustic wave file of the downloaded part.
Further, when downloading the designated sound wave file, the industrial control opportunity detects whether the same sound wave file exists in the industrial control opportunity:
when the sound wave file does not exist in the industrial personal computer, the industrial personal computer judges that the downloading is the first downloading and starts to download from the initial position of the sound wave file;
when the sound wave file exists in the industrial personal computer, the industrial personal computer compares the stored file size with the sound wave file size in the information area of the storage board of the sound wave instrument, and when the stored sound wave file size is smaller than the sound wave file size in the information area, the industrial personal computer judges that the downloading is interrupted and the secondary downloading is started due to accidents in the process of primary downloading; when the stored sound wave file size is equal to the sound wave file size in the information area, the industrial personal computer judges that the sound wave file is downloaded.
Further, the length of the sound wave file in the step 2 is the number of bytes occupied by the sound wave file.
Further, the length of the sound wave file is the storage block number at the beginning and the storage block number at the end of the sound wave file.
Further, 1024 bytes may be stored in each of the memory blocks.
Further, when determining the initial storage block number in the step 3, dividing the byte number by the byte number stored in each storage block and rounding, and adding the rounded integer to the initial storage block number of the sound wave file to obtain the initial storage block number of the sound wave file during secondary downloading.
Further, when determining the position of the secondary download of the sound wave file, multiplying the initial storage block number by the byte number stored in each storage block, wherein the position of the product in the sound wave file is the position of the primary download interruption, and after determining the position, the position can be sent and the secondary download is started.
Further, during downloading, the acoustic wave information stored in the acoustic wave instrument storage board can be sent to the industrial personal computer in a data stream mode.
Further, when the secondary download is performed, the industrial control computer sends data to the storage block at the beginning of the secondary download obtained after calculation, and the data records are stored into a file.
Compared with the prior art, the method has the beneficial effects that whether the sound wave file exists in the industrial personal computer is judged before each downloading, so that whether the sound wave file is downloaded once can be effectively judged, the stability of the industrial personal computer during downloading is improved, and the method is suitable for various disconnection conditions. Meanwhile, the sound wave file is stored by using a plurality of storage blocks, and the specific position for initial downloading can be determined by calculating the number of the storage blocks, so that the time waste is avoided.
