摘  要:近年来我国高速铁路发展极其快速，列车速度已经达到350km/h，相应的对于异物侵限监控系统提出了更高的要求。本文针对于异物侵限实时监测系统设计出一整套信息采集、信息处理和信息传输的硬件电路及软件设计。

本文首先分析了国内外的研究现状，对于防灾安全监控系统的组成和功能以及主要监测内容进行了介绍。在分析各种监测技术的基础之上，对于不同地段的监测技术进行了确定。

系统设计主要采用单片机k60实现信息的采集，利用摄像头进行现场图片的拍摄，SD卡硬件电路的设计用来实现信息的存储，同时A6模块负责信息的无线传输。其一系列的静电保护电路、电源供电电路以及无线插座电路等保证了系统工作的稳定以及信息传输的安全可靠。最后设计出系统的主要软件算法流程图，通过调用Opencv函数库实现对于信息的判断、处理和传输，提高了系统的信息化水平。

Design of real - time monitoring system for foreign invasion of high - speed railway

Abstract:In recent years, the high-speed railway in China is evolving at an increasing rate, and the speed of train has reached 350km/h, which asks more requirements for foreign invasion monitoring system. According to real-time monitoring system for foreign invasion, this thesis tries to design a set of hardware circuit and software design in terms of information collection, information processing and collection transmission.

Firstly, the thesis tries to analyze the current research status at home and abroad, and introduce the constitutions, functions and monitoring contents of the disasters prevention and safety monitoring system. On the basis of analyzing different kinds of monitoring technology, the thesis tries to confirm some specific technology according to different terrains.

During the procedure of systematic design, the designer tries to use MCU K60 to collect information. And the hardware circuit design of SD card is used to store information. At the same time, the modules of A6 is used to realize wireless transmission. Besides, a series of electrostatic protection circuit, power supply wireless socket circuit can ensure the stability of the system as well as the safety and reliability of information transmission. Last, the thesis tries to design the main software flow diagram of this system. By using Opencv function library, the system will realize the function of information judgement, information processing and information transmission, which will improve the information level of the system.
