摘要
基于实验室气体安全问题频出的情景,研发性能强大、架构轻便的报警器是一个值得研究的课题。在实验室中配置该报警器以检测环境中的温度、湿度、氧气浓度,当检测数值高于或低于安全范围时,将会由传感器发出警示信号。同时,通过轻量化Web框架Flask进行后端设计,经过树莓派进行数据处理后可以在浏览器网页端实时监控受检测指标变化,并且保存历史记录。
Based on the situation of frequent gas safety problems in the laboratory,it is worth studying to develop a powerful and portable alarm.The alarm is equipped in the laboratory to detect the temperature,humidity and oxygen concentration in the environment.When the detection value is higher or lower than the safe range,the sensor will send out warning signals.At the same time,through the lightweight web framework flask for back-end design,after the raspberry pie data processing,it can real-time monitor the changes of detected indicators in the browser Web site,and save the history.
