Design Of Building Fire Environmental Safety Monitoring System

In the fire rescue work,many factors such as high temperature and smoke pose a serious threat to rescue workers.If fire scene environment cannot be understand quickly and accurately,rescue workers cannot perform rescue work.In this paper,based on the study of past fire rescue methods,a detection system for fire scene environment based on aircraft deployment is designed.The system includes onboard system and ground station system.The sensors in the airborne system are responsible for collecting various data during the mission of the quadrotor,and the wireless module of the airborne system is responsible for transmitting the collected environmental information parameters to the ground station.After the ground station receives the data packet,it uses the wireless transmission data protocol to analyze and process the data packet and parse out the environmental parameter information.The article begins with an introduction to the subject’s background and the objectives and methods of this study.Firstly,this paper introduces the selection of sensors,the parameters of the selected LCD screen,the basic characteristics,and the characteristics of the wireless module.Then,this paper introduces the SPI protocol,the technical characteristics of the SPI protocol,the SPI interface instructions and the operating modes of the NRF24L01 wireless module.Moreover,this article discusses the design of the system hardware,including the overall hardware structure of the fire monitoring system,the selection of the main control chip,the design of the signal sensor,the connection mode of the LCD screen,and the entire process of the system software design.In the end,the design of the monitoring system was debugged and operated to monitor the experimental fire.In the safety monitoring system designed in this paper,the human body infrared sensors,flame sensors,and smoke sensors in the airborne system can acquire signals during the experiment and wirelessly transmit data of wireless module was enhanced through the NRF24L01,which has a long transmission distance and reliable data transmission.After the ground station system receiving the data packet,it uses the wireless transmission data protocol to analyze and process the data packet,and the display screen can display the information collected by several sensors accurately.The safety monitoring system designed in this paper can realize the real-time monitoring of the fire scene and the system can help the rescue workers to grasp the situation of the fire scene at the first time.
