摘要
针对分布于一定区域内不同地点的多个电子时钟同步问题,设计出一套基于GPS技术和无线传感器网络的时钟无线同步系统。该系统是由一台授时器和多台电子时钟组成的无线网络,论文设计了基于无线传感器网络的授时系统结构,定义了通信数据帧格式、给出授时器和电子时钟的硬件框图,编写了该系统的软件程序。
This paper analyzed the inside and outside malfunction and corresponding protection of the capacitor, and exactly defined the installation principle of the present capacitor protects. Imbalance relay protection of capacitor has been analyzed and compared, which in terms of the primary and secondary device coordination, and provided the selecting type technological principle of this kind of protection.
