【摘要】：高鐵相對(duì)與普通列車具有其獨(dú)特的優(yōu)勢(shì)：載客量多、輸送能力大、速度快、正點(diǎn)率高并且舒適方便。從2008年8月1日我國(guó)第一條具有完全自主知識(shí)產(chǎn)權(quán)的高速鐵路——京津城際鐵路開通運(yùn)營(yíng)，我國(guó)高速鐵路發(fā)展步伐逐步加快。與普通列車相比，高速鐵路的高時(shí)速要求其監(jiān)測(cè)時(shí)間更短更準(zhǔn)確。在這一背景下，設(shè)計(jì)出可靠實(shí)時(shí)的安全監(jiān)測(cè)系統(tǒng)十分必要。 本文針對(duì)高鐵的具體要求，設(shè)計(jì)了一款實(shí)時(shí)監(jiān)測(cè)高鐵安全參數(shù)的系統(tǒng)，它能夠?qū)崟r(shí)地將采集到的信息處理發(fā)送，作為交通道路部門確保高鐵安全的依據(jù)。本文的研究問題包括：系統(tǒng)的總體設(shè)計(jì)、傳感器的選型、軟硬件設(shè)計(jì)和終端圖形化開發(fā)。 針對(duì)系統(tǒng)技術(shù)特點(diǎn)，采用基于ARM9內(nèi)核的S3C2440處理器為主控制器，通過各種傳感器的性能參數(shù)比較，選擇出符合系統(tǒng)監(jiān)測(cè)標(biāo)準(zhǔn)的傳感器，輔以外圍電路完成系統(tǒng)的硬件設(shè)計(jì)。軟件設(shè)計(jì)方面系統(tǒng)采用嵌入式Linux為操作系統(tǒng)，Qt/e為圖形化開發(fā)工具。通過傳感器驅(qū)動(dòng)的開發(fā)和軟件的設(shè)計(jì)，將傳感器監(jiān)測(cè)得到的數(shù)據(jù)傳送給主控制器進(jìn)行處理，將其上傳并存儲(chǔ)。其中數(shù)據(jù)的處理由ARM處理器進(jìn)行，與上位機(jī)的通訊基于TCP/IP協(xié)議，數(shù)據(jù)存儲(chǔ)于上位機(jī)中。這樣的設(shè)計(jì)既能充分利用ARM處理器的運(yùn)算功能，還考慮到了數(shù)據(jù)存儲(chǔ)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.
