主要针对临床上对病患体温、脉率和呼吸频率3个生理信号的数据采集和传送，介绍一款自动巡测系统。该无线生理参数监护系统可以实现：脉搏信号的拾取和分析，计算脉率；通过Tsic506高精度温度传感器对体温数据进行读取；通过对呼吸时鼻腔内的温度变化的数据计算呼吸频率；实时地进行传输显示体温、脉搏和呼吸频率的数值；在数据的采集节点进行呼叫，数据接收节点设有相应的复位按钮。本系统各功能模块分工明确、结构清晰，日常功能的修改、扩展和维护容易，同时还具有对设备要求低、开发时间短，对写入的程序可以进行加密等优点。%The clinical data collection and the transmission for the three physiological signals of the temperature, the pulse rate and the respiratory rate are presented. The wireless physiological parameter monitoring system can achieve the following functions: picking and analysis of the pulse signals and the pulse rate calculating;temperature data reading through Tsic506 high precision temperature sensor; calculating respiratory frequency through the data of the respiratory temperature which changes in the nasal cavity; real-time transmitting and displaying the data of the temperature, the pulse and the respiration frequency;calling in the data collecting node without the corresponding reset button. Each module of the system has functions of clear labor division, clear structure, easy to future functional modification, extension and maintenance. At the same time, it also has advantages of the lower requirement for equipment and the short time for developing and can make encryption for the written procedures.
