摘要
针对胸外科监护室智能监护的需求问题,构建基于物联网智能监护系统。其中,采用ZigBee技术和WiFi联网对数据进行采集与传输;为加强监护室的安全,对传统的加权几何定位算法进行优化,得到改进后的定位算法,提高对患者定位。结果表明,改进后的定位算法在定位测试中,最大距离的定位误差为0.41 m,平均距离的定位误差为0.22 m;具体应用测试认为,定位效果良好,准确显示环境信息。综上,本研究构建的胸外科监护室监护系统可实现患者的准确定位,得到监护的目的。
Aiming at the demand of intelligent monitoring in Thoracic Surgery ICU,an intelligent monitoring system based on Internet of things is constructed.Among them,ZigBee technology and WiFi networking are used to collect and transmit data;In order to strengthen the safety of the ICU,the traditional weighted geometric positioning algorithm is optimized,and the improved positioning algorithm is obtained to improve the positioning of patients.The results show that the positioning error of the maximum distance is 0.41m,and the positioning error of the average distance is 0.22m;The specific application test shows that the positioning effect is good and the environmental information is accurately displayed.In conclusion,the Thoracic Surgery ICU monitoring system constructed in this study can achieve the accurate positioning of patients and obtain the purpose of monitoring.
