Design and Implementation of Fire Alarm Device Based on Singlechip

At present, with the rapid development of society, it brings convenience to people's work and life, but also brings many potential safety hazards. Fire is the most common and frequent occurrence of these hazards. Therefore, this paper designs and implements a fire alarm device based on singlechip. When a fire occurs, a large number of smokes and higher temperatures will be generated. The device can detect smoke signals and temperature signals through smoke sensor detection module and temperature sensor detection module, and send them to singlechip to decide whether to alarm. In the specific implementation process, it is divided into two parts: The first part is the hardware design, including singlechip module, sensor module, display module, alarm module and key module. The second part is the software design, which uses C language to develop the alarm system through Keil uVision 4 software. At the same time, in order to make it more convenient for users to use, emergency alarm key and threshold adjustment key are designed, which can realize emergency alarm function and threshold parameter preset function. The experimental results show that the device has stable structure, good performance and practical value.
