The above is the TXT format file data content, the file name "V5813101.012"
The format is: the first line, the description of the data file, as follows
Ordinal parameter number long remark
1. File Number 5 bytes
2. Year 5 bytes less than 5 bytes, front space
3. Month 5 bytes
4. Length 5 bytes.
5. Width 5 bytes
6. Alternate field 15 bytes Pre-fills each byte with a "-" (minus sign).
7. The height of 5 bytes high low when the front space.
8. Identification 5 bytes filled with "4"
9. Subsequent reserved bytes are populated with a "-" (minus sign) so that the parameter row is the same length as the subsequent data record line.
10.v1.004 bytes
11. Carriage return newline 2 bytes

Start with the second line
The minute data record line starts at line 2nd of the file, each hour is a record line, the length of each row is equal, and the record length is 60x5+6. The sorting order is: 2-bit "date", 2-bit "hour", 60-minute *5+2-bit "carriage return".

1 months for a file, there's Wood there's a very simple way to read the data and then write to the database.
A perfect match.
