Fire Alarm System Design Based on Single-chip Microcomputer
Abstract
In real life, fire detection processing is an important part of fire alarm system, It is widely used in all kinds of buildings and used to implement the buildings fire alarm and processing to reduce the loss brought about by the fire, It is the necessary way for the current social security of the people's production and living security.
The design is the use of single chip microcomputer as the core, with modular design as design ideas, from the aspects of hardware and software for the design of fire alarm system. According to the mission requirements, design flow chart of system, choose the used hardware design, introduction and explanation, for each module component to write the initial value setting, temperature sensor signal collection and processing, smoke signal collection and processing, alarm system, fire protection system and so on. Using the simulation software Proteus simulation.
The design system at the scene of the fire temperature and smoke concentration exceed limit, the system Settings can realize sound and light alarm, and take effective measures, such as automatic smoke, spray extinguishing agent reduces the chance of the scene of the fire fire expand, can effectively suppress the fire. This system has high sensitivity, accurate, and suitable for precision under the environment of a variety of fire alarm, realized the accurate fire detection and alarm, fast response. Is the strong of social security protection.
