摘　　要：目的:设计一种无线遥测式电子温度计,可以使医护人员在不接触患者的情况下监测患者的体温。方法:该系统以新型单片机MSP430F413为核心;温度采集传感器采用热敏电阻;模数转换时利用单片机内的比较器和定时器进行斜边A/D转换;无线通讯部分使用NRF2401芯片;系统与计算机之间采用串行通信方式进行通讯。结果:该系统在-40～85℃范围内工作,在体温范围内精度达到0.1℃。结论:该系统可以准确地测量体温,同时通过无线通讯方式把数据传送到接收端,再通过串行通讯方式传递给计算机。计算机记录体温变化曲线提供给医护人员参考。Objective To design a new kind of wireless monitoring thermometer which can help the doctor to monitor the patient＇s temperature without touching them. Methods The system is based on a new kind of single chip MSP430F413, the thermistor was used in temperature detect part; the single chip＇s comparator A and timer A was used in A/D converter part to realize slop A/D; the NRF2401 chip was used in wireless transmission part; the system is connected with PC in the way of serial communications. Remdta The thermometer can work in -40 to 85℃ when the temperature is near animal heat, the thermometer is most accurate which precision is 0.1℃. Conclusion The system can measure the patient＇s temperature accurately, at the same time, the temperature data is sent to the receiving end in the way of wireless communication, and then data is sent to PC, which PC can record the temperature curve data and help the doctors to diagnose.
