摘要: 针对脑力工作者在工作状态管理领域中存在实时性不足、个性化缺失,以及脑科学技术与管理流程融合度低的问题开发了一种脑机接口与智能体协同的工作效率优化系统。系统采用8通道 OpenBCI(Open Brain- Computer Interface)设备采集脑电信号; 在情绪识别方面, 通过短时傅里叶变换和微分熵构建时频图像, 输入改进型 Pyramid SR-CNN(Super-Resolution-Convolutional Neural Network)模型进行 3 分类(负性、 中性、 正性), SEED(SJTU Emotion EEG Dataset)数据集上准确率达94.01%; 在疲劳监测方面, 基于加权 θ/β 功率比实现 分类(正常、 轻度疲劳、重度疲劳), 引入多通道空间权重策略提升鲁棒性。系统通过 LSL(LabStreamingLayer) FastAPI WebSocket 构建低延迟数据通路, 前端基于ECharts实现受试者状态可视化, 并调用COZE智能体定时 生成反馈报告。 为验证系统可行性实验招募 名受试者完成不同强度脑力任务结果表明该系统能有效识别情绪波动及疲劳状态性能显著优于传统行为监测方式;实现了输出对个体脑电特征的适配干预方案可助力工作效率提升为脑力工作者的工作状态管理提供了科学技术路径。

Abstract: A collaborative brain-computer interface integrated with an agent-based framework is presented to optimize work efficiency, with key challenges in work-state management for knowledge workers-specifically, inadequate real-time capability, lack of personalization, and poor integration between neuroscience tools and management workflows-being tackled. The system acquires EEG(Electroencephalogram) signals via an 8-channel OpenBCI(Open Brain-Computer Interface) device. Time-frequency images are constructed using short-time Fourier transform and differential entropy for emotion recognition, and then processed by an enhanced Pyramid SR-CNN ( Super-Resolution-Convolutional Neural Network) model for three-class classification ( negative, neutral, or positive), achieving 94. 01% accuracy on the SEED(SJTU Emotion EEG Dataset) dataset. For fatigue monitoring, a three-class classification ( normal, mild, or severe fatigue) is performed based on a weighted θ/β power ratio, with multi-channel spatial weighting strategies incorporated to improve robustness. A low-latency data pathway is established using the LSL(Lab Streaming Layer) and FastAPI WebSocket. The front end visualizes subject states via ECharts and invokes a COZE agent to generate periodic feedback reports. Six subjects performed cognitive tasks of varying intensity to validate system feasibility. Testing results show that the system effectively detects emotional fluctuations and fatigue states, significantly outperforming conventional behavioral monitoring methods. By generating intervention protocols adapted to individual EEG characteristics, the system enhances work efficiency and offers a scientifically grounded technological approach for managing the working states of knowledge workers.
