【摘要】：高铁相对与普通列车具有其独特的优势：载客量多、输送能力大、速度快、正点率高并且舒适方便。从2008年8月1日我国第一条具有完全自主知识产权的高速铁路——京津城际铁路开通运营，我国高速铁路发展步伐逐步加快。与普通列车相比，高速铁路的高时速要求其监测时间更短更准确。在这一背景下，设计出可靠实时的安全监测系统十分必要。本文针对高铁的具体要求，设计了一款实时监测高铁安全参数的系统，它能够实时地将采集到的信息处理发送，作为交通道路部门确保高铁安全的依据。本文的研究问题包括：系统的总体设计、传感器的选型、软硬件设计和终端图形化开发。针对系统技术特点，采用基于ARM9内核的S3C2440处理器为主控制器，通过各种传感器的性能参数比较，选择出符合系统监测标准的传感器，辅以外围电路完成系统的硬件设计。软件设计方面系统采用嵌入式Linux为操作系统，Qt/e为图形化开发工具。通过传感器驱动的开发和软件的设计，将传感器监测得到的数据传送给主控制器进行处理，将其上传并存储。其中数据的处理由ARM处理器进行，与上位机的通讯基于TCP/IP协议，数据存储于上位机中。这样的设计既能充分利用ARM处理器的运算功能，还考虑到了数据存储的安全性。
[Abstract]:Compared with ordinary trains, high-speed rail has its unique advantages: large capacity, high speed, high punctuality and convenience. From Aug. 1, 2008, the first high-speed railway with its own intellectual property rights, the Beijing-Tianjin Intercity Railway, has been put into operation in China, and the development of high-speed railway in China has been accelerated step by step. Compared with ordinary trains, high speed trains require shorter and more accurate monitoring time. Under this background, it is necessary to design a reliable and real-time security monitoring system. According to the specific requirements of high-speed railway, this paper designs a real-time monitoring system of high-speed railway safety parameters, which can real-time process and transmit the collected information as the basis for the traffic road department to ensure the safety of high-speed rail. The research problems include: the overall design of the system, sensor selection, hardware and software design and terminal graphics development. According to the technical characteristics of the system, the S3C2440 processor based on the ARM9 kernel is used as the main controller. By comparing the performance parameters of various sensors, the sensors that meet the system monitoring standards are selected, and the hardware design of the system is completed with peripheral circuits. In software design, embedded Linux is used as operating system QT / e as graphical development tool. Through the development of sensor drive and the design of software, the data obtained from sensor monitoring is transmitted to the main controller for processing, and it is uploaded and stored. The data processing is carried out by the ARM processor, and the communication with the host computer is based on the TCP/IP protocol, and the data is stored in the upper computer. This design not only makes full use of the computing function of ARM processor, but also takes into account the security of data storage.
