Analysis on the Circuit Design of Fire Alarm

Abstract

In the large airtight cinema and school, there are a lot of people in public places, thus the fire safety problems always attach great importance to everyone. The appearance of fire alarms can definitely help audience who are immersed in watching movies and students who are listening to the teachers carefully to remind them of a fire, so they can leave the scene in time and reduce property losses. This paper will take the fire alarm circuit as an example to realize the combined logic circuit by using various integrated circuits of different scales. This design is very flexible, effective and operable. In the actual process of use, the appropriate scheme can be selected according to the design requirements and the resource of the device. The object of study is a logic circuit, which is composed of an integration gate or a medium scale synthesizer. The experimental methods include practical ideas, application of Boolean logic principles, and sampling of data from others through the Internet, which are mentioned at the end of the paper. The conclusion is that abstract logic can be used step by step to design a practical and effective circuit diagram.
