【摘要】：智能穿戴设备近几年来发展迅速,已经成为全球范围内增长快速的高科技市场之一,具有巨大的发展潜力,已经成为当今国内外许多专家学者们的研究热点,并开始运用于医疗监护、运动监测、定位和智能服装等多个方面。数据无线传输在智能可穿戴服装的研究中起着至关重要的作用,本文使用BLE4.0应用于智能穿戴领域有一定的前沿性,具有很大的研究和应用价值。本文基于蓝牙无线短距离传输技术,提出了智能服装中具备层次化功能的整体模型,在此模型下重点分析了数据无线传输层。针对人体着装的实际应用环境,分析了硬件传感设备和所采集的数据特点,设计了基于BLE4的数据传输协议层,最终通过搭建的实测环境验证可行性和合理性。其中数据采集主要包括温度、湿度和加速度运动状态。本文的研究内容主要包括以下几个方面:1.针对智能穿戴服装范围内的数据传输过程,研究的具体过程包括:归类总结传感器采集过程和数据,设计采集数据格式,无线近距数据传输的性能,以及数据的后期处理及各功能层的联动测试。2.本文将嵌入设备分别设置了主机模式和从机模式,实现了主机与从机的蓝牙通讯,主机与PC机之间的串口通讯,完成了具备完整功能的数据传输实测平台。3.在层次化系统下遵循已有的数据通讯标准协议扩展了部分协议内容,设计了适合智能穿戴服装的数据无线传输协议层,实现了基于最新低功耗蓝牙BLE4.0技术的主从扫描、连接建立、数据传输和连接断开等步骤。4.本文用温度传感器、温湿度传感器和加速度传感器采集人体的温度、湿度以及运动状态等评价服装穿着舒适性的生理参数和运动指标,研究随运动状态变化对应的温度和湿度变化的规律,验证并实现了平台的实际应用价值。
[Abstract]:Smart wearable devices developed rapidly in recent years, has become one of the high-tech rapid market growth worldwide, has great potential for development, has become a hot research topic of many experts and scholars at home and abroad, and they have been applied to the medical monitoring, motion detection, multiple positioning and intelligent clothing. Plays a vital to study the effect of wireless data transmission in intelligent wearable clothing, this paper use the BLE4.0 application in the field of intelligent wearable has a certain edge, is of great value in research and application. Based on Bluetooth wireless short distance transmission technology, put forward the overall model with hierarchical function in intelligent clothing, this model focuses on the analysis of the data the wireless transmission layer. According to the human dressing application environment, analyzes the hardware sensors and data acquisition characteristics, designed based on BLE4 data The transport protocol layer, finally through the test environment verifies the feasibility and rationality of building. The data collection mainly include temperature, humidity and acceleration of the moving state. The main contents of this paper include the following aspects: 1. for smart wearable clothing within the scope of the data transmission process, the specific process of the research includes: classified sensor acquisition process and data. The design of data format, the performance of wireless short-range data transmission, and the linkage test.2. post processing data and the function layer of embedded devices are respectively arranged in master mode and slave mode, realized from the host and Bluetooth communication machine, serial communication between the host computer and PC machine, data communication protocol is completed the measured data transmission platform.3. has complete function in the hierarchical system follow the existing extended part of the agreement, designed for wisdom Can the wireless data transmission protocol layer wearing apparel, realizes the connection master-slave scan, the low power Bluetooth technology based on BLE4.0, data transmission and disconnect the steps of using.4. temperature sensor, humidity sensor and acceleration sensor to collect temperature of human body, physiological parameters and motion evaluation of wearing comfort and humidity the movement state, temperature and humidity changes corresponding to the change of state of motion with law, validate and implement the platform's application value.
