Based On Tcp/ip Protocol Embedded Fire Alarm System Design And Research

Down through the ages, fire accident is one of the potential safety hazards which seriously threats people s lives and property, so humans have developed and used fire accidents detected and monitored system for hundreds years. The history of this system is from personal guards to non-attended substation, and with the shortage of labor automatic and intelligent system more and more interest people. With the implementation of building fireproofed principle, fire detected system is broadly applied, which as a result greatly developed it. Because of the high rise building s burgeoning, the request to fire alarm system is more and more strict and rigid. Moreover, for the widely usage of Internet, it must be effective to combine single fire alarm system to the Internet. This paper proposed a embedded fire alarm system based on TCP/IP protocol after analyzing and comparing some existing fire alarm system. This system is of simple structure and cheap price, as well as in mobile monitoring and fast installing.This paper will use chip fire sensors as signal collecting, 89C51 single-chip microcomputer as control center, to implement embedded and network-connected fire alarm system based on TCP/IP protocol. The paper started with introduction of the embedded system and some background of fire alarm system, and then simply introduced some knowledge of TCP/IP protocol. Next I introduced the structure of system in details, especially the implementation of some sub-module. At last, I showed the implementation of TCP/IP protocol in single-chip system.This research indicates the proposed system is stable and reliable, and low in price, and of network communication. In one word, this system can satisfy practice request of fire monitoring and alarming.
