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.
