基于ZigBee技术的儿童生理参数采集与情绪检测系统

System of Physiological Parameters Collection and Child-emotion Recognition based on Zig Bee Technology

为了实现儿童情绪检测与识别的功能,我们提出了穿戴式生理参数检测系统的概念,并设计了以CC2530芯片为核心,以Zig Bee为传输技术的穿戴式儿童情绪生理参数检测系统。系统采集处理的生理指标主要有心电信号、体温和皮肤电反应。传感器获取的模拟信号经过前置滤波放大后,通过A/D转换器转换成数字量,然后经由Zig Bee无线网络节点上传至上位机,由系统实时地处理数据。经仿真试验,系统具有较高的识别准确率。

In order to realize the function of child- emotion recognition,we proposed the concept of wearable system and designed a wearable system of physiological parameters collection and child- emotion recognition based on Zig Bee technology and CC2530 chip.The physiological signals collected were electrocardiogram（ ECG）,skin temperature（ SKT） and galvanicskin response（ GSR）. The physiological signals acquired by sensor would be amplifiered and converted by ADC,then transmitted to supervisory computer with Zig Bee wireless data communication module. Supervisory computer dealed with the data in real time. The simulation test shows that it＇s an effective system to recognize emotion by physiological signals.
