The main contents and results of this paper are listed as follows:Based on the finite element analysis software ANSYS establish a bridge of three-dimensional mechanical model of CWR;Based on an actual project,calculate different conditions of three forms of bridge and research the reasonable removal scope of fastener;Research on the allowed lock temperature rail track construction of partial maintenance of range.By analyzing the result obtain the best way to replace the support of a bridge and the range of removal of the bearing and permission of rail temperature of construction.It supports some recommendations for the replacement of city construction maintenance.

本文主要研究内容为：基于有限元分析软件ANSYS建立了桥上无缝线路三维力学模型；依据某实际工程，分析计算了三种桥梁形式在不同顶升工况下的钢轨和扣件受力，研究了扣件的合理拆除范围；对维修后局部钢轨施工锁定轨温的允许范围进行了研究；分析得出了城轨桥梁更换支座施工的最佳顶升方式、扣件拆除范围和允许施工轨温，为城轨桥梁更换支座的施工维修提出了一些建议。

Firstly, the realizable ways of signal detection and sample、 power circuit and the application of low-consumption model of MSP430 are discussed, by which the required function of current protection and voltage protection can be realized. Secondly, different protection algorithm based on micro-computer are discussed in this article, and from the virtues and defects of Fourier algorithm, an improved algorithm is put forward, and the importance of the improved algorithm is displaced. Thirdly, according to the national standard of GB/T18858 .3-2002, the principle of networklization of intelligence trip relay and how to realize it are mentioned. Lastly, using the current conditions, the test of precision is done. The experimental date present that the system is working well and can realize the real-time function of on-line detection.

首先在硬件设计上，对于信号检测、处理、电源电路、MSP430系列单片机的低功耗方式应用以及人机接口电路等问题提出了实现方法，基本实现了大范围电流、电压信号实时监控等功能；其次，本文还对当前各种微机保护算法进行了介绍，分析了傅立叶算法在实现智能脱扣器保护功能中的优缺点，并针对傅立叶算法中计算偏于复杂的问题对该算法进行了改进，提出了基于FFT的改进算法，通过算法的分析和比较，对改进算法的性能给出了评价；然后结合我国现场总线国家标准GB/T18858.3-2002讨论了DeviceNet现场总线在实现脱扣器网络化的原理，实现方法，论述了通讯接口电路的设计；最后利用现有条件，对装置进行了性能测试，试验数据说明系统工作状态较好，可以满足低压配电网自动化对低压脱扣器的各项要求。
