摘要
火灾自动报警系统主要用于各种高层建筑和公共设施中,实现对这些场所火情的早期报警功能,减少火灾带来的损失。以单片机为核心、模块化为设计思想进行火灾报警控制系统的设计。根据系统的需要,设计了软件流程图,编写了传感器初始化、温度信号采集、烟雾浓度信号采集、声光报警等程序,并仿真调试成功。本系统在周围温度超过上限值并且烟雾浓雾大于上限值时,声光报警立即同时体现,能大大减少火灾的误报率,且具有精确度高、灵敏度高、适用范围广等优点,特别适合在工业与民用建筑方面使用。
Automatic fire alarm system is mainly used in various highrise buildings and public facilities to realize the function of a fire early warning, and to reduce fire damage. The design of automatic fire alarm system is based on the modularized design, using the singlechip as a core. The software flow chart, and the programs of sensor initialization, temperature signal collection, smoke concentration signal collection, audible and visual alarm are provided so as to satisfy the system's needs. Ultimately, the programs are simulated successfully. In this sys tem, audible and visual alarm will emerge at the same time when ambient temperature and smoke concentration exceed the upper limit values. The design not only greatly reduces the rate of false fire alarm, but also has many advantages of high precision, high sensitivity, and a wide range of application. So this system is especially suitable for the usage in industrial and civil ar chitecture.
