移动端智慧化二级氧气箱小程序的开发及应用

The Development and Application of Intelligent Two-Stage Oxygen Tank Applet on Mobile Terminal

随着医院的不断发展,病区对氧气的需求量越来越大。为保证临床诊疗工作顺利开展,需实时监控医院的氧气压力,以在压力不足时及时采取应急措施。为此,该研究开发了一种移动端智慧化二级氧气箱小程序。首先,在病区管道井安装型号为SC-LP-CAM的摄像头,并将摄像头拍摄的二级氧气箱仪表图片传输至数采物联云平台,数采物联云平台可识别图片中的氧气压力值。其次,以微信小程序为平台,利用数采物联云平台提供的API接口,每隔10 min获取1次仪表图片和压力值,并自动刷新显示界面;当小程序获取的氧气压力值<0.3MPa时,利用榛子云短信平台所提供的API接口进行短信报警提醒。最后,设计展示4 h内二级氧气箱的压力值和压力趋势图,以便监测二级氧气箱的性能。经过2个月的试运行,该小程序可按时、准确显示二级氧气箱仪表图片和压力值,且经测试报警功能正常,4h压力值和压力趋势图页面清晰、数据准确度高。

With the continuous development of hospitals and the increasing demand for oxygen in wards,it is necessary to monitor the hospital's oxygen pressure in real time to take emergency measures in case of insufficient pressure,to ensure the smooth progress of clinical diagnosis and treatment.For this purpose,a intelligent two-stage oxygen tank applet on mobile terminal was developed in this study.Firstly,a camera with the model SC-LP-CAM was installed in the pipeline well of the ward,and the two-stage oxygen tank instrument images captured by the camera were transmitted to the data acquisition IoT cloud platform,which can recognize the oxygen pressure values in the images.Secondly,with the WeChat mini program as the platform,the instrument image and pressure value were obtained every 10 minutes by utilizing the API interface provided by the Data Acquisition IoT Cloud Platform,and the display interface is automatically refreshed;When the oxygen pressure value obtained by the small program was less than 0.3MPa,the API interface provided by the Hazel cloud SMS platform was used for SMS alarm reminder.Finally,this design presented the pressure values and pressure trend chart of the two-stage oxygen tank within 4 hours,in order to monitor the performance of the two-stage oxygen tank.After 2 months of trial operation,the small program can display the picture and pressure value of the secondary oxygen tank instrument on time and accurately,and the test alarm function is normal.The 4 h pressure value and pressure trend diagram page is clear and the data accuracy is high.
