妊娠分娩期子宫肌电信号特征图谱构建方法、装置、设备及介质
By employing methods such as data collection, preprocessing, standardized annotation, and feature extraction, a uterine electromyography signal feature atlas library was constructed. This solved the problem of the correlation between uterine electromyography signals and the uterine activity state during pregnancy and childbirth in existing technologies, and achieved efficient state recognition and prediction.

Abstract
本发明涉及妊娠分娩期子宫肌电信号特征图谱构建方法、装置、设备及介质。子宫肌电信号特征图谱构建方法包括：采集不同产妇不同子宫活动状态下的子宫肌电信号并预处理；进行含基本信息、子宫活动状态、信号质量标签的标准化标注；提取时域、频域、非线性特征；经相关性分析、随机森林模型筛选及有效性验证，得到区分子宫活动状态的多维度量化特征，构建特征图谱库；还可基于该特征训练深度学习模型，实现子宫活动状态预测。本发明解决了现有技术中子宫活动状态与子宫肌电信号缺乏统一关联的问题，为妊娠及分娩子宫活动状态监测提供可靠支撑，辅助临床决策。
