摘　　要：论述了一种基于LPC2114和μC/OS-II的无线传感器网络的软硬件实现方法。选用LPC2114作为控制器,以μC/OS-II构建软件平台,采用蓝牙作为无线通信手段,以温湿度传感器、光敏电阻和传声器构成传感器数据采集单元。针对小规模无线传感器网络的特点,提出并实现了一种基于单路径的路由算法,简化了网络,增强了可靠性。测试证明,网络健壮,传感信息准确。This paper expatiates on the software and hardware design methods of Wireless Sensor Networks based on uC/OS-II and LPC2114. It chooses LPC2114 as the controller, uses uC/OS-II as the software platform, adopts the Bluetooth as the means of wireless communication and takes temperature and humidity sensor, photosensitive resistance and microphone as the sensor data collection units. Aiming at the characters of small capacity wireless sensor networks, it proposes and realizes a routing algorithm based on single path. It can enhance reliability by simplifying the network. The test demonstrates that the system can work steadily and the sensor information is correct.
