吊瓶和药液被传感器所测重。随着药水的减少。重力传感器获得的数据用 zigbee传递给该程序后，对数据进行处理形成百分比转化为液面信息和药水滴完所剩余的时间，并将数据存入指定文件中，通过局域网链接，使得上手机端上能都看到液面和所剩时间，并液面快将为0时在电台平提示护士换药或者停药。-The bottle and the liquid is measured by the sensor weight. With the drops of medicine. Gravity sensor to obtain the data using ZigBee transfer to the program and to process the data form percentage conversion for surface information and drops dripped off the rest of the time, and data will be stored in the specified file, through the LAN link, the mobile phone terminal can see the liquid surface and the time remaining and surface soon to be 0 in radio that nurses dressing or discontinuation of the drug.
