The invention relates to a special data transmitting system for fire combat, in particular to a data transmitting system, which belongs to the fire security field. The special data transmitting system solves the problem that at present, the communicating way in the fire extinguishing and rescuing scene is single, and information can not be promptly interacted. The system comprises the steps that a special data transmitting fixed terminal for the fire combat is connected with an Internet network, and wireless link is established between the Internet network and a CDMA network. A special data transmitting mobile platform for the fire combat establishes wireless connection with the fixed terminal through a CDMA network; data transmission is performed through the connection of a GPRS network,and a mobile phone and a PDA; the data transmission is performed through the connection of a spot temporary network Ad hoc and a mobile terminal. A plurality of special data transmitting mobile terminals for the multiple fire combats performs the data transmission through the connection of the CDMA network and the fixed terminal; the data transmission is performed through the connection of the Adhoc network and the mobile platform. The invention adopts a real-time information intercommunicating technology, to share battlefield information in the maximum limit, so that the combat command realize information obtained real-time and information transmission network, and the whole combat level of an army is improved.
