摘　　要：目的为减少培养箱使用过程中,由于外部光照和温湿度异常,导致内部温湿度无法降低,而造成的“虚假”故障现象和潜在风险。方法研发一种基于乐鑫ESP8266 Wi-Fi芯片的检测报警装置,利用传感器采集培养箱外部光照与温湿度数据,上传至云平台进行分析处理,超出阈值后发出报警信号至客户终端,及时提醒相关人员做进一步处理。管理人员可在PC端和手机客户端实时监测数据,提前预判故障,进行预防性维护。结果该装置能准确检测到培养箱外部光照强度和温湿度,当光强或温度超过设定阈值达5 min时,一台在用培养箱会发出长达2 min警报,并具有远程查阅、实时监测、历史查询和报警等功能。结论该装置在临床使用中能提前、有效给出安全警报,减少无效报修,辅助工程师快速排除故障,同时可以帮助管理人员追踪、分析历史数据,总结故障发生的频率、原因等,进一步指导后续相关工作。Objective In order to reduce the use of incubator,due to the abnormal external light and temperature and humidity,the internal temperature and humidity cannot be reduced,resulting in“false”failure phenomenon and potential risks.Methods Through the development of a detection and alarm device based on ESP8266 Wi-Fi chip,the front-end sensor was used to collect the external light and temperature and humidity data of the incubator and upload them to the cloud platform for analysis and processing.After the threshold is exceeded,the alarm signal will be sent to the client terminal to timely remind relevant personnel for further processing.At the same time,the manager can monitor the data in real time on the PC and mobile phone,predict the fault information in advance,and carry out preventive maintenance.Results The device could accurately detect the external light intensity,temperature and humidity of the incubator.When the light intensity or temperature exceeds the set threshold for 5 min,it will give an alarm.One incubator in use will give an alarm for 2 min,and has the functions of remote access,real-time monitoring,history query and alarm.Conclusion In clinical use,the device can give safety warnings in advance and effectively,reduce invalid repair application,assist engineers in troubleshooting and solving problems quickly.At the same time,it can help managers track and analyze historical data,summarize the frequency and causes of failures,and further guide the follow-up work.
