本文首先提出了无线传感网络节点的基本要求，并针对其要求成功实现了无 线传感网络节点的设计，为了满足定位与跟踪的特殊需求，特别设计了超声波定 位的传感器板。论文叙述了节点的设计过程及测试内容。运用计算机、调试器、 节点等硬件组成网络硬件平台，并运用TinyOS软件开发系统组网，实现了温度 显示、节点的定位等功能，自行研制了数据管理监控软件，可以监测节点的温度、 距离等信息，也可以观察网络节点的拓扑变化情况。最后，总结了整个系统的优 缺点，并提出了下一步工作计划。 -Wireless sensor networks(WSNs)

函数发生器是一种在科研和生产中经常用到的基本波形产生器，集成函数 波形发生器一般都采用ICL8038或5G8038，而它们只能产生300kHz以下的中低频正弦波、矩形波和三角波，且频率与占空比不能单独调节，从而给使用带来很大不便。本文介绍由LM324和稳压管组成的低频函数波形发生器，该电路能够产生正弦波、方波和三角波信号，频率能以10Hz的间隔在20Hz～20KHz范围内调整。-Function Generator is a scientific research and production often use the basic waveform generator, integrated function waveform generator usually used ICL8038 or 5G8038, and they only have a 300kHz following the low-frequency sine wave, square wave and triangular wave, and frequency and duty cycle alone is not regulated, so as to enable using bring a lot of inconvenience. This paper introduces the LM324 voltage regulator tubes, and the low-frequency waveform generator function, the circuit can produce sine, square and triangular wave signal frequencies of 10Hz to 20Hz at intervals within ~ 20KHz adjustment.
