摘　　要：以单片机为控制中心,采用各种传感器进行信号采集,将采集的信号进行滤波、逐级放大,然后将放大的信号经过模数转换器(ADC)转化为便于单片机处理的数字信号.处理后的数据可通过液晶显示屏显示出来,也可通过串口连接上位机由电脑进行较为复杂的数据分析并显示信息波形.本设计通过测试人体的体重、体温、血压、心率心音的各项指标,判定一个人的健康指数,并根据测试结果给出相应的健康提示.The project designs a Home Health indexes Analyzer,which includes micro-control sys- tems and signal acquisition systems. Its features are micro-control systems consisting of micro control- lers,which are connected with A/D converter circuit, display screen, keyboard and serial port input cir- cuit. Signal acquisition system is made by the A/D converter circuit,which is connected with blood pres- sure measurement, weight measurement circuit, the temperature measurement circuit, heart rate, heart sounds measurement circuit,and temperature measurement circuit. The project brings a variety of detec- tors together in one set. It can not only test blood pressure, body weight, body temperature, heart rate, heart sounds easily meeting the demand of people,but also be able to test the health indicators of testing analysis and the stored ones. The analyzer can also analyze indicators which have been stored during a pe- riod of time. The instrument based on the measured body indexes,analyses the physical health compared with stored medical knowledge. What＇s more,it can remind the user of their health conditions in a warm way of tips or notes. At last, users can adjust to their lives reasonably, prevent and early discover some diseases through the instrument.
