| Blood pressure is one of the most significant physiological parameters in human life,appropriate blood pressure is the precondition to maintain proper metabolism.Therefore,to judge whether you're health or not,it's important to test blood pressure regularly and scrutinize daily change of it.According to the current development of electronic sphymomanometer,wireless and smart blood-pressure testing system based on blue-tooth 4.0 is devised in accord with Internet+ when there are some defects about data management in traditional electronic sphymomanometer,In this system,pressure sensor is used to gather cuff pressure in the process of presure loading,which is sampled through ADC before pressure value is collected via computation and analysis of micro-processor,and then the data is loaded in customized protocol and transimitted wirelessly to a mobile device terminal with blue-tooth 4.0.Human-to-machine interaction and wireless communication are introduced into blood-pressure detecting system.Based upon analysis of function and performance of wireless blood-pressure detecting system,structural analysis and design procedures are used to complete circumstantial design,system implementation and data testing of the entire system.During the process of system design,ideology of software engineering is utilized.Once the system is completed,automation in the blood-pressure detecting process is realized and tested data can be transmitted wireless into mobile device terminal and stored to be checked by patients at their disposal.Patients can gain information about their physical health at all times.In comparison to traditional counterpart,this system is more secure,more flexible and wider in testing range.Ultimately,The design and implementation of wireless and smart blood-pressure detecting system is described in this treatise.The system has reliability and praticability.The implementation and utility of system has a very important value and meaning in human life. |
