Research On Fire Internet Key Technology Based On ZigBee

With the continuous expansion of city,population density and industry clusters gradually increase,resulting increasing fire safety problems.Due to the low intelligence,high energy consumption,poor accuracy,high-rise building wiring problems and other reasons of conventional fire alarm systems,more and more difficult to meet the requirements of the current fire alarm.Need a more efficient,more safe,more reliable,more energy-efficient fire monitoring solution.Based on the ZigBee technology into the design of fire protection system.ZigBee technology is a short-range,self-organizing,low complexity,low power wireless communications technology.Implement the RF transceiver function and information processing module with CC2530.The CC2530 full function design with extended interface backplane.CC2530 modules,WiFi module and sensor module embedded in it.Built to access Internet network ZigBee-WiFi gateway and data forwarding in sensor networks node.Study of ZigBee wireless networking process.Fully functional node based on Z-Stack protocol stack equipment and simplified function nodes software for the device.In the areas that need fire alarm installation of sensor nodes.Rely on nodes in ad hoc network technology.Set up wireless fire sensor networks.By sensing function of sensor nodes.Fire information collection fire zone.Networking,communications equipment,data acquisition functions.By setting up a virtual server.Coordinator node receives the data through the Internet ZigBee-WiFi gateway to upload to PC system.Written in LabVIEW software in PC.Alarm threshold parameters and set the value.Analytical sensors collecting monitoring information packet.Information on temperature,smoke and CO alarm threshold is exceeded.Alarm messages displayed in real time on the PC software.Finally,to test the whole system.To achieve the desired design requirements.
