A complete automatic fire alarm system is ahigh-rise building fire life and property when it was a strong guarantee. This paper describes a smart buildings usedin thefire alarmsystem. Using AT89S52microcontroller-based controller, DS18B20 testing temperature, digital display of temperature, to achieve fire alarm; stepper motor as the reaction device, the implementation of security on the protected items. In this paper, fire alarm controller and the detector made a thorough study and comprehensive exposition of the fire alarm controller and the detector hardware and software design. Fire alarm system controller AT89S52 microcontroller using automatic fire alarmsystem, it realized the fire detection and delivery of information. And analysis of the application of automatic fire alarm system status, suggesting that the development ofautomatic fire alarm system trends and directions, and the principle and module design, system functions and features a detailed explanation.KEY WORDS: AT 89S52 devices, temperature sensors, stepping motor, automatic fire alarm system目 录 第一章 浅谈火灾自动报警技术的应用现状 ................... 7 第一章 浅谈火灾自动报警技术的应用现状 ................... 7 1.1 适用范围过小 ............................................................................... 7 1.2 智能化程度低 ............................................................................... 7 1.3 网络化程度低 ............................................................................... 7 第二章 浅谈火灾自动报警系统应用技术的发展趋势 ............ 8 2.1 网络化 ............................................................................................ 8 2.2 智能化 ............................................................................................ 8 2.3 火灾探测技术的多样化。
