Detailed Description
The technical solutions in the embodiments of the present invention are clearly and completely described below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
A UID code feature extraction method for an electronic detonator comprises the following steps:
respectively extracting a feature code, a year, a month, a date and a serial number in the UID code of the electronic detonator;
storing the feature codes by adopting 1 byte;
the years and the months are combined together to be stored separately, in particular, after the years and the months are combined into hexadecimal data, the data are stored by 1 byte,
the specific mode of combining and converting the date and the serial number is that the date and the serial number are directly spliced into a group of data end to end, and the data are converted into a hexadecimal integer and then stored by adopting 3 bytes, namely, the UID code is compressed into 5 bytes for storage.
The UID code of the electronic detonator adopts ASCII code, one character adopts one byte for storage, and the UID feature extraction method is as follows: the digital portion in the UID is converted to integer data. The integer data described later is described in hexadecimal (0 x).
For example, the UID code of an electronic detonator is: 581900330A 00112.
In the UID code (1), the character 'A' represents the characteristic code of the UID and is stored by one byte, namely 0x41 in hexadecimal; (2) in the UID code, a character string '19' represents a date, '03' represents a month, then a single digit '9' and the month '03' of a year are extracted and combined into hexadecimal data 0x93 which is stored by a byte; (3) in the UID code, a character string "30" indicates a date, and "00112" indicates a serial number, two character strings are spliced end to form "3000112", and then converted into hexadecimal integer data 0x2DC730, which is stored in three bytes. Finally, the UID code is compressed into 5 bytes for storage, that is, a [5] ═ {0x41,0x93,0x2D,0xC7,0x30 }.
In summary, the method for extracting the characteristics of the electronic detonator UID code extracts the characteristic code, the year, the month, the date and the serial number in the electronic detonator UID code, then respectively stores the characteristic code by using 1 byte, stores the characteristic code by using 1 byte in the year and the month, combines the date and the serial number into a group of data, converts the group of data into an integer and stores the integer by using 3 bytes, so that the electronic detonator UID code is compressed into 5 bytes, the quantity of data transmission is compressed, the anti-interference capability of communication is improved, the power is reduced, the program and decryption time are optimized, and the method has popularization and application values in the use process of the electronic detonator.
