The Design Of Oxygen Measurement System In Hospital Based On ZigBee And Androir Client

As the medical level of China improves,the demand for the accuracy of oxygen measurement is ever growing.The building of the hospital,which has been built,has high economic cost and difficult construction in the wiring implementation.The introduction of Wireless Sensor Network(WSN)technique in hospital oxygen measurement,deployment of the corresponding function node in the hospital,which forms the mesh network structure by self-organize,then,through the PC upper monitor and the Android client monitoring the change of parameters,a complete wireless sensor network system is formed.This system could be used for the collection of parameters such as oxygen usage,and has a certain application prospect.Firstly,this paper introduces the state and deficiency of the oxygen measurement system,proposing the application of wireless sensor network technology in the field of oxygen measurement in hospital to achieve the function of parameter acquisition,real-time monitoring and oxygen leakage reminder.The system analyses the advantages and disadvantages of networking mode and client comprehensively,selects WSN based on ZigBee technology and designs hospital oxygen measurement system and the Android client for handheld terminal equipment.Secondly,the hardware and software of the system are designed,and CC2530 is selected as the core module of the system.The EPI series gas flow sensor is used to collect the oxygen consumption and the temperature humidity sensors,the smoke sensors are used to collect the environmental parameters.This paper designs the key module,Wi-Fi module and sensor module of the node in detail.In addition,this paper introduces the software design of the networking between the system nodes,the software design of the Wi-Fi module,the design of monitoring interface of the PC upper monitor and the building of the server.Finally,this paper designs the Android client login interface,data display interface,network communication and tests the system in hardware and software and the Android client,realizing the data acquisition and transmission,exception alarm and data query,also the communication between the server and the client.The experiment shows that the design of the hospital oxygen measurement system based on ZigBee and the Android client has high application value in the actual hospital environment.
