The Design And Realization Of The Laboratory Intelligent Security Alarm System Based On STM32

In recent years,the level of science and technology in our country has been continuously improved,everything is connected,and the intelligence of security products has gradually attracted people’s attention.Colleges and universities in our country undertake the important task of scientific research and teaching,and the safety of laboratories cannot be ignored.Therefore,it is of great engineering significance to design and develop a set of intelligent security alarm system for the laboratory to monitor the environmental conditions in the laboratory in real time,so as to prevent the laboratory safety accidents in time and effectively.This paper designs an intelligent security alarm system which can be used in laboratory security monitoring.The system can realize intelligent unlocking through fingerprint and key password at the same time,and the display screen can switch to display the user interface and the real-time monitoring screen collected by the camera through touch control.The wireless communication between the fire detection system and the main controller is realized by HC-12 module.The main control chip realizes two-way short message communication with users through SIM7600 CE module,and at the same time uses WIFI wireless communication to upload the collected data to the cloud platform.Users can observe indoor environment data through mobile phones,further improving the function of human-computer interaction.
