Research And Design Of Fire Alarm System Based On Power Line Carrie Communication

The fire has the feature of happening chance and randomness in time and places.The monitoring center need to timely receive the information once on fire, thus alarmthe threat of fire to people in danger through a microphone. The center also needs tobroadcast the specific circumstances to stabilize their emotions and tell them how toescape. The common fire alarm system is based on wired and wireless networks, butthese alarm systems spent higher construction costs and are difficult to maintain sothat can not be widely applied.In order to solve this problem, this paper designs a kind of fire rescue indoorpositioning system based on power line carrie fire alarm system. Power line carrier asthe power system-specific means of communication to transmit a fire alarm signal toexisting power lines as a carrier, the biggest feature is the need to re-set up thenetwork and maintenance, as long as there are wires, data transfer can be carried out,without the wired network the impact and influence of wiring wireless network signalstrength, can achieve a wide range of coverage. The system uses power line carriertechnology, the key technology is to ues power line to achieve data transmissionwhich breaking the limitations of traditional smoke detecting system. The second keytechnology is the use of single-chip, routers and PC equipment and the technology ofLwip protocol. The system uses C/S and B/S hybrid architecture model for networkcommunications. The use of the domain name system dynamic analysis comes routerand port forwarding function, the visualization of information through the Sockettransmitted to the client browser to achieve remote fire smoke monitoring networkaccess to fixed domain function.
