在新兴的物联网(IoT)中，无线传感器是物理世界和网络空间之间的重要中介。在许多远程监控和交互应用中，高达MB/S的高速率数据流可能需要通过互联网从无线传感器传输到云计算服务器，并由远程服务器以准实时的方式进行处理。这些应用通常要求大幅降低这些基于互联网的网络物理系统的通信带宽、响应延迟和功耗。为了满足这些高效利用通信、计算和电力资源的需求，我们开发了一种先进的可穿戴传感器平台(AWSP)，它将强大的系统级芯片(SoC)处理器、智能电源管理单元、高精度实时时钟和多功能外围设备集成到一个微型模块中。该传感器能够在将数据上传到手机、计算机等其他设备之前执行复杂的数据预处理，包括实时伪影和噪声去除、数据压缩，甚至特征提取。此外，随着嵌入式实时Linux操作系统的安装，该传感器为系统开发人员提供了熟悉和强大的软件开发环境，以构建计算密集型实时应用程序。本文介绍了该系统的设计和开发过程。
In the emerging Internet-of-Things (IoT), wireless sensors are the vital mediators between the physical world and the cyber space. In many telemonitoring and interactive applications, high-rate data streams up to MB/s may need to be transported from the wireless sensors to the cloud computing servers over the Internet and processed by the remote servers in quasi-real time fashion. These applications generally demand substantial reduction of communication bandwidth, response latency and power consumption of these Internet-based cyber-physical systems. To tackle these demands for efficient use of communication, computing and power resources, we developed an advanced wearable sensor platform (AWSP) which integrated a powerful system-on-chip (SoC) processor, a smart power management unit, a highly accurate real-time clock and multi-function peripherals into a miniature module. This AWSP designed to function is capable of performing sophisticated data pre-processing including real-time artifact and noise removal, data compression, and even feature extraction before uploading the data to other devices like mobile phone, computer, etc. Furthermore, with the installation of embedded real-time Linux operating system, this sensor provides a familiar and powerful software development environment for system developers to build their computation-intensive real-time applications. This paper presents the design and development process.
