兰州交通大学毕业设计(论文) - I- 摘要: 计算机联锁从研制初期到目前已经历了 30 多年的时间,它以其巨大的优越性吸引着人们。我国计算机联锁系统的研究也取得了巨大的成就,目前国内存在着很多型号的计算机联锁系统。铁路运输要求高安去性和高效率,无论在技术上还是经济上都有优势的计算机联锁系统受到了青睐。本设计所选站场为虚拟站场——环球线南极站下行咽喉,设计内容包括:信号平面布置图、双线轨道电缆图、联锁表、电缆径路和电缆网络图、系统结构图、组合排列表、室内设备布置图以及工程数量表。其中信号平面布置图能正确反映计算机联锁室外主要设备的布置情况,主要有道岔的位置、警冲标位置、信号机的布置和计算它的位置。双线轨道电路图主要是实现极性交叉的配置,在图中还要进行扼流变压器的布置和送受电端的布置。联锁表的内容包括了基本进路的选择、敌对信号的确定、轨道区段侵限检查等。电缆径路图是施工挖沟的依据,设计出清晰合理的电缆径路图不仅便于施工维修还可节约成本,而设备的串接顺序及各个设备间距离和电缆芯数都能在电缆网络图中表示出来。本次设计的系统选择了简单的双机热备系统,组合排列表中主要表明了信号组合、道岔组合以及轨道组合的排列情况以及组合的组成。室内设备布置图包括控制台室、继电器室和电源屏室内各种设备的布置。关键词:计算机联锁;工程设计;信号平面图布置; 兰州交通大学毕业设计(论文) - II- puter interlock ing has gone through more than 30 years from the early development to today, its great superiority attract people's attention. Our puter interlocking system has made great achievements also, there are many types puter interlocking system. Rail transport requires high security and efficient . Relay on the advantage of both technically and economically puter interlocking system e a darling. The design choose an virtul station — the Antarctic station downstream throat of u niversal line, the project includ ing signal plan e arrangement diagram , two line track c ircuit diagram, interlocking table, cable path and work diagrams, system structure .Unit block arrangement table, indoor equipment and the number of tables.
