The Study Of Wireless Fire Prevention System Based On IOT

With the rapid development of social economy, the urban population density andelectrical equipment increased, fire hazard more and more, Once the fire, the fire spreadlosses will be incalculable. Traditional fire alarm device exists problems such asmaintenance difficulties and complex electrical wiring, at the same time it is often appearomission phenomenon such as leaders, that unable to meet the modern society to therequirement of fire hazards early found early treatment.In this paper, the research and design of wireless sensor fire IOT monitoring alarmsystem bring wireless sensor technology is introduced into the fire alarm monitoring, usingZigBee wireless communication technology instead of traditional fire detection alarmequipment line connection. To build fire alarm monitoring center in real time to monitoroperation of fire alarm equipment, to prevent the occurrence of fire due to equipmentfailure omission of leaders. Using the theory of temperature field to monitor and analysisthe environment temperature distribution, scientific layout of sensor nodes. Application ofthis system can realize to monitor the environment temperature, the gas concentration ofreal-time collection and analysis, the implementation of fire prediction, achieve the goal ofearly warning and alarm.Wireless sensor designed in this paper fire IOT system is mainly composed of firedetection terminal nodes, routing nodes and the coordinator node, each node connect toZigBee technology to realize the wireless transmission of data between the coordinatornode via a serial port or public network, then transmission the data to the center of the firemonitoring PC, realize the real-time monitoring of the monitoring environment. In theaspect of the system hardware mainly from the coordinator node and routers, terminaldetection node three parts of the transmission circuit and data acquisition part weredeveloped; As for the software part of the system builds with the Z-stack protocols,workflow development of three kinds of nodes, through the program compiledimplementation of terminal detection node data gathering and routing node and the coordinator node of data transmission. Finally ate the coordinator node and datatransmission between the sensor node test to achieve the research content of this project.
