基于大数据的睡眠中人体压力数据可视化分析系统介绍
本系统是一套面向睡眠健康领域的大数据分析平台，通过Hadoop分布式存储和Spark计算引擎处理海量睡眠监测数据。系统采用Django作为后端框架，结合Vue+ElementUI+Echarts构建可视化前端界面，实现对睡眠过程中人体压力数据的深度挖掘。核心功能涵盖压力水平指标均值分析、生理指标关联度分析、睡眠压力水平分布分析以及综合健康指数趋势分析四大模块。系统利用Spark SQL对HDFS存储的压力数据进行快速查询，通过Pandas和NumPy完成数据清洗与统计计算，最终以Echarts图表形式呈现分析结果。整个架构充分发挥大数据框架在处理大规模时序数据方面的优势，为用户提供睡眠质量评估和健康趋势预测的技术支撑，同时系统预留了个人信息管理和密码修改等基础功能，保障数据安全与用户体验。
