Based on the study of the security risks in fire rescue of buildings and the application of location technology in building fire rescue, a more reliable location service system in building fire rescue is given. The system makes use of long waveform, which has higher penetration factor and longer distant transmit ability, to transmit the signal. IEEE standard is supported in the system's wireless network. The Fire Command Center or headquarter can view all the firemen's location in the design drawings of the building through a Monitoring Terminal. To be convenient to view the current status of the fire rescue, Monitoring Terminal can be a pad or mobile device. It validly ensures the quick and reasonable response for the fireman in a predicament, and put out the fire efficiently. However, to be more reliable, the system should pre-installed lots of Positioning-Assistant Device, which costs a great deal in both finance and time.
