| Balise and Line Electronic Unit are the key devices of China Train Control System (CTCS). Balise is based on the principle of the electromagnetic coupling, used to calibrate the local of the train at the Specific locations, transmit data between trackside device and on-board device at high speed. The information about safety of Train Control, which Balise transfer to the ATP vehicle equipment, includes the line information, the fixed information, the limited speed information and so on. And all the information is stored with the Balise telegram. So the Balise telegram directly relates to the traffic safety.But because of late research on Balises system in China, the safeguard means and the management experience are lacked for us. Especially large numbers of telegram programming and management task is on the artificial level, and it is inefficient and fallible. The thesis is on the research of the process of the telegram programming and management, and the software is designed and completed.Follows are the work that has been done:1. First, introduce the Balise development, specially the situation of the Balise telegram programming and management in China and other foreign countries, and illustrate the sense of the thesis;2. Analyze the requirements of the process of the Balise telegram programming and management altogether, bring forward the software in the whole, and describe the system network structure and function module;3. The system comprises two part of the software. One is about telegram information management, based on B/S model; the other is about Balise telegram programming and the management of part of data, based on B/S model. The thesis expatiate the related method and design the software date structures, module functions, Human-Machine Interface and so on;4. Give a presentation of Balise telegram coding strategy, and analyze its effect of the telegram safety. Aimed at the safety of the system software, do some research;5. Based on JSP and Visual C++ 6.0 software development conditions, program; the Balise telegram Programming and management software, and complete the elementary functions; finally, analyze the foreground of the software. |
