基于单片机的实验室水电气安全监控系统设计

Laboratory Safety Monitoring System of Water,Gas and Electricity Based on Single-chip Microcomputer

近年来,火灾、漏电、爆炸及有毒有害气体泄露等实验室安全事故时有发生,对生命财产安全造成了严重的威胁.针对以上问题,本设计采用单片机STC89C52为主控制芯片,使用电流互感器、流量传感器、气体传感器进行信号采集,用NRF24L01无线传输模块进行通信,电磁阀、继电器、红外遥控等进行自动化控制,从而实现一种成本低廉、功能多样、人机界面良好的简易实验室水电气安全监控系统.

In recent years,laboratory safety accidents such as fires,leakages,explosions,and toxic and harmful gas leaks have occurred frequently,which have caused serious threats to the lives and property of students.Aiming at the specific conditions of university laboratories,the system adopts micro control unit(MCU) STC89 C52 as the main control chip,and uses current transformers,flow sensors and gas sensors for signal acquisition,NRF24 L01 wireless transmission modules for communication,solenoid valves and relays for automatic control,so as to achieve a safety monitoring system with simple structure,low cost,diverse functions.It can real-time monitor the water,electricity and gas safety in the laboratory.
