English Abstract
With the rapid development of new building techniques, there is an increasing need for improved early-warning fire alarm systems.
Fire disaster is a great threat to lives and property.
Fire alarm system provides real-time surveillance, monitoring and automatic alarm.
It sends early alarm when the fire occurs and helps to reduce the fire damage.
The last years have witnessed a rapid development in wireless network area.
There are many wireless monitoring and control application for industrial and home environments which required longer battery life, lower data rates, and less complexity than from existing standards.
For such wireless applications a standard called ZigBee has been developed by the ZigBee alliance based upon the IEEE 802.15.4 standard.
In this thesis, the proposed fire alarm system has been design based on ZigBee wireless sensor network.
The proposed system operates in real time, gives the exigencies of fires.
The architecture of a proposed fire alarm system based on wireless sensor network is composed of a hardware and software design.
The hardware design consists of monitor center (master node), repeater node and sensor node (end device).
The hardware circuitry of the sensors node constructs of three types sensors: temperature (NTC) sensor, photoelectric smoke sensor and MQ-2 gas sensor.
ATmega32 microcontroller is the data processor whiles the XBEE transceiver represents the wireless transmission in this node.
Repeater node circuitry is consists of Atmega32 microcontroller and XBEE transceiver.
Also, the hardware of master node is XBEE transceiver attached to PC.
The software design deals with monitoring center, repeater node and sensors node.
The monitoring center is responsible for monitoring or displaying the whole sensors status in all nodes of the system.
It is confirmed by the experiment that the system can realize the fire detection and alarm.
The average current consumption for sensor node is 210mA, with 5V power supply.
More current is drawn by MQ-2 gas sensor about 140mA.
The repeater node consumes current of 80mA and the master node about 30mA.
The system runs with Visual Basic 6.0 development environment for monitoring in master node, which current dissipated 30mA.
The proposed system has response time less than 0.5 second and consumed less than one second to demand information of one sensors node.
The efficiency of the system is more than 98% and the sensors node cost about 60000 ID, also the repeater node cost is 45000 ID, and 35000 ID for master node cost.
