decoding the currently received data packet;
comparing the decoding result of the currently received data packet with the decoding result of the received data packet, and judging whether the content of the currently received data packet is the same as the content of the received data packet;
if the data packets are the same, discarding the currently received data packet;
and if the content of the current received data packet is different, playing the content of the current received data packet and/or storing the content of the current received data packet.
5. The utility model provides a wide-narrow band fuses communication transmission device, is applied to the sender, its characterized in that includes:
the first acquisition module is used for acquiring data information to be transmitted;
the first sending module is used for sending the data information to be sent through a narrowband network and a broadband network at the same time;
the first sending module is further used for carrying out data packet division processing on the data information to be sent to obtain an original data packet;
packaging the original data packet according to the narrowband signal transmission requirement to obtain a narrowband data packet;
packaging the original data packet according to the broadband signal transmission requirement to obtain a broadband data packet;
simultaneously, the narrowband data packet and the broadband data packet are respectively transmitted through a narrowband network and a broadband network
The first sending module is further used for adding a unique ID number, a data packet serial number, a data type zone bit and a data length before the data to be sent; the unique ID number of the machine and the serial number of the data packet are used for indicating the uniqueness of the data packet, the type flag bit is used for indicating the type of the data to be sent, and the data length refers to the byte number of the data to be sent;
also, the application and receiving end includes:
the second acquisition module is used for receiving and obtaining data information through a narrowband network and a broadband network at the same time;
and the data information processing module is used for screening the currently received data information according to the received data information so as to remove repeated data and playing and/or storing the data information in real time.
