本文從最底層入手，介紹了自主研發(fā)的無線傳感器網(wǎng)絡(luò)（WSNs，Wireless Sensor
Networks）節(jié)點(diǎn)硬件平臺，及軟件平臺在硬件上的移植。其中，硬件平臺采用了分層復(fù)用的思想，功能模塊齊全；而軟件平臺選擇μC/OS-Ⅱ這個多任務(wù)實(shí)時微操作系統(tǒng)來管理應(yīng)用軟件。整個平臺的硬件和軟件融為一體，為WSNs 的應(yīng)用研究提供了一套有利的開發(fā)平臺。

Abstract: From the bottom level, this paper presents a platform, integrated with hardware and
software, for the research of Wireless Sensor Networks (WSNs), and gives the way to make them compatible with each other. Layer Division Multiplexing (LDM) is designed in our hardware platform which includes complete modules in need; in the other aspect, the real-time kernel μC/OS-Ⅱ is used as software platform to manage the running of application programs. As a whole, it provides a development platform for the application research of WSNs.
Key Words：WSNs; hardware platform; node; μC/OS-Ⅱ
