Digital alarm system for dormitory in post-epidemic era

Abstract

Colleges and universities are person-intensive places, and it is difficult for them to prevent and control the epidemic after students return to school. In the post-epidemic era, college students face many difficulties in health and safety. In view of the poor fire-fighting facilities, difficult evacuation and difficult temperature monitoring in and out of dormitories, this paper developed a digital alarm system in the post-epidemic era with college dormitory as the carrier. The system was divided into two parts: the master controller and the monitoring nodes. The monitoring nodes were installed in each dormitory room. The data was collected by temperature sensor and smoke sensor, and the data was transmitted to the upper computer by wireless module. According to the functional requirements of the digital alarm system, the upper computer interface had designed two modules: temperature anomaly alarm and fire alarm. The upper computer could display the data monitoring situation of each dormitory and realized digital alarm according to the data analysis results.
