Abstract:This paper is based on the technology of Internet of things to design a human physiological parameters monitoring system so that we can monitor the human body physiological parametersand detect the patient's potential health risks。 Three sensors such as HK-2000B+, DS18B20 and BP300 are chosen to measure pulse, body temperature, blood pressure。 The enlarge filter circuit for signal amplification and filtering the noise signal is designed after。 And then it introduces the wireless gateway, the design of the monitoring station, the features of ZigBee technology and network topology structure。 It briefly illustrates the process of adding sample tasks and structures。 And the accuracy of the temperature index collection is tested at the end。 This design can reduce the manpower management of various problems。 It has the application value and a lot of advantages such as low cost, low power consumption, good real-time, embedded sex strong, safe and convenient。 It is suitable for application in the field of interference is not too big。 It only analyzed the accuracy of the test since the limitation of cost and other conditions。 Some actual problems may be not taken into account。
