Embodiment 1

[0036] Embodiment 1: as shown in Figure: 1, a kind of positioning method of the personnel location evacuation system based on RFID fire scene, its method step is specifically as follows:

[0037] Step 1: Install RFID readers and RFID antennas in each room, corridor, main entrance and exit, stairwell or other escape exits and monitoring nodes of the building. The RFID reader radiates magnetic field energy to the space through the RFID antenna and forms A magnetic field covering a certain area;

[0038] Step 2: the personnel information is pre-associated with the radio frequency card 4, and stored in the database of the fire monitoring host 8, and the position of the RFID reader 1 is set and saved in the fire monitoring host 8 in advance;

[0039] Step 3: When a fire breaks out, the fire monitoring host computer 8 sends a personnel location instruction to the RFID reader-writer 1 through the fire-fighting bus, and the RFID reader-writer 1 starts to emit radio frequency energy. ...

Embodiment 2

[0044] Embodiment 2: as figure 2 As shown, a positioning method of an RFID-based fire site personnel positioning and evacuation system is characterized in that the method steps are specifically:

[0045] Step 1: Install RFID readers and RFID antennas in each room, corridor, main entrance and exit, stairwell or other escape exits and monitoring nodes of the building. The RFID reader radiates magnetic field energy to the space through the RFID antenna and forms Cover the magnetic field area in a certain area, and install smoke and temperature fire detectors at each monitoring point;

[0046] Step 2: When a fire occurs, the smoke and temperature fire detectors 5 installed at each monitoring point first detect the changes in smoke and temperature and upload them to the fire monitoring host;

[0047] Step 3: The fire monitoring host computer 8 issues a command to control the sound and light emergency alarm 5 to issue an alarm, prompting the personnel in the building to evacuate q...

Abstract

The invention discloses an RFID-based fire scene personnel positioning and evacuation system. The system is characterized by comprising a fire monitoring host, a temperature-sensing and smoke-sensingfire detector, a sound and light emergency alarm, an RFID (radio frequency identification) reader-writer, an RFID (radio frequency identification) antenna and a radio frequency card. The radio frequency card is in wireless connection with the RFID reader-writer through the RFID antenna. The RFID reader-writer, the temperature-sensing and smoke-sensing fire detector and the sound and light emergency alarm are respectively connected with the monitoring host. The system is novel in structure, fast and accurate in positioning, simple in system construction or hanging connection, low in cost, fastin fire scene rescue and the like.

Description

technical field [0001] The present invention relates to the technical field of RFID (Radio Frequency Identification), in particular to a method for using RFID technology to locate personnel at a fire scene and a personnel evacuation system based on the method. Background technique [0002] As we all know, the environment of the fire scene is complex, accompanied by thick smoke, high temperature, water vapor, explosion, etc., and the changes can not be predicted at any time. Whether the exact position of the trapped personnel can be determined in the first time and the timely implementation of evacuation and rescue operations is of great significance for fire rescue operations, which makes us urgently expect to find a method that can realize the positioning of fire scene personnel. [0003] At present, the existing fire scene personnel positioning technologies mainly include GPS technology and ZigBee technology. [0004] Among them, the use of GPS technology to locate person...
