In order to accurately monitor and monitor fire signals,reasonable system design and research are carried out based on simple chemical plant conditions.Based on the STC89C52 single-chip microcomputer,and then using CO,temperature,smoke and other sensors,wireless communication board,and alarm monitoring board,a single-chip-based chemical fire intelligent monitoring and alarm system is designed.It has the characteristics of low development cost,stable monitoring of various fire characteristics,and timely alarm;Fire signals are monitored in real time through sensing modules such as temperature,toxic gases and smoke,and the characteristic parameters of the signals are subjected to A/D conversion and algorithm analysis in sequence.After analysis,the wireless communication module is used to realize long-distance transmission of data.Real-time monitoring and timely alarm are realized with the help of cameras,buzzers,liquid crystal displays and other instruments.Experimental verification shows that the system is highly operable,can detect the situation in chemical plants in real time,and has functions such as early warning,timely alarm,and stable remote monitoring.
