And when the short message type in the packet header of the short message data packet is used for indicating the preset short message, comparing the data in the packet header of the short message data packet with the stored key words, acquiring the preset short message corresponding to the key words after the comparison is successful, and taking the acquired preset short message as the short message content obtained by decoding.
generally speaking, after a low frequency receiving chip receives specific coding information containing a low frequency transmitting terminal identifier and transmits the specific coding information in a 2.4GHz frequency band, surrounding base stations can receive the specific coding information in the 2.4GHz frequency band, then decode the specific coding information to obtain the identifier in the specific coding information, and if the identifier is stored in the base station, the mining mobile terminal with the identifier is determined to be a legal mobile terminal; if the identification is not stored in the base station and the information is matched with the personnel information with one code all the time and only one piece of coded personnel information is available at the same time, the identification is stored in a legal identification list, namely the identification is used as a legal identification, and the identification state is displayed through the terminal and the identification authentication is completed.
