Description: 火灾作为一种发生频率高、破坏性强的灾害,已受到了人们的大力重视。本文依据传感器检测技术和单片机技术的发展，从人们日趋严重的安全问题出发，设计了适用于居民住房的基于单片机的智能火灾报警系统。该系统采用了感温和感烟探测器相结合的探测方法，能更加准确的报警，从而降低误报率。以AT89S52单片机为控制器，通过温度传感器、烟雾传感器采集现场火灾信号，经信号处理、A/D转换送入单片机，单片机经过数据处理、与设定值比较、判断是否超过报警上限，若未超过，则由数码管显示器显示烟雾浓度和温度；若超过，则由数码管显示的同时实现声光报警，使人们能够及时发现火灾，并采取有效措施，扑灭初期火灾。智能火灾报警系统具有实时监控和报警的功能，是一种结构简单、性能稳定、使用方便、价格低廉、智能化的报警器，具有较好的实用性。-Fire is a kind of high frequency, destructive disasters, which was given a strong attention. In this paper, based on the development of sensor technology and computer technology, starting the security problem that people increasingly serious, smart fire alarm was designed based on single chip microcomputer system.The designed system is suitable for the residents of housing. The system employs a temperature detector and smoke detector to detect fire together they can give a more accurate alarm and reduce the false alarm rate. Using AT89S52 as controller, the temperature sensor and smoke sensor are employed to acquired the fire signal. After the signal was processed and A/D conversion it was in put the SCM. Then the data was processed by the SCM, Comparing with the preset value and determining whether it exceeds the alarm limit or not. In normal condition four 7-segment LEDs shows the smoke concentration and temperature. When it fire, the designed system gives light and sound to alarm p Platform: |
