    摘要:

    目前针对人体活动识别的数据采集硬件系统研究有限，且存在可参考的数据集单一和泛化性能较低的问题。本文设计一个低功耗、支持数据实时传输、模块化的数据采集系统，并提出一种具有随机性和交叉性的数据采集方法。首先搭建低功耗采集平台进行数据的采集、无线收发和预处理；其次制定全面且精确的采集方案，提高数据集的丰富度；最后用2D-CNN神经网络对不同模式下采集到的数据集进行模型训练。实验结果表明,该采集系统结构合理，具备低功耗特性，能够确保数据传输具备实时性能；该采集系统的应用极大地提高了数据集的质量；获得的数据集在深度学习模型上的准确率可达92.54％；相较于传统数据集，新数据集在人体活动识别任务中表现出更为显著的效果，该采集系统和数据集的开发为神经网络应用提供便利。

    Abstract:

    Currently, research on data acquisition hardware systems for human activity recognition is limited, and there is a problem of a lack of diverse and generalized reference datasets. In this paper, we design a low-power data acquisition system that supports real-time data transmission and propose a data acquisition method with randomness and crossover. Firstly, a low-power acquisition platform is built for data acquisition, wireless transmitting and receiving, and pre-processing; secondly, a comprehensive and accurate data acquisition scheme is developed to improve the generalization of the new dataset; and finally, a 2D-CNN neural network is used to train a model for the acquired dataset in different modes. The experimental results demonstrate that the designed data acquisition system has a reasonable structure and low power consumption, ensuring real-time data transmission. The application of this system greatly improves the quality of the dataset. The obtained dataset achieves an accuracy of 92.54% on deep learning models. Compared to traditional datasets, the new dataset shows significantly better performance in human activity recognition tasks. The development of this data acquisition system and dataset provides convenience for neural network applications.
