自动控制毕业论文.docx

兰州交通大学毕业设计(论文) - I- 摘要计算机联锁是目前最先进的车站联锁设备,该系统信息量大,速度快,操作方便, 提高了车站的自动化程度和作业效率,具有广阔的发展前景。本次选择了计算机联锁工程设计作为毕业设计课题,采用的是二乘二取二型计算机联锁系统制式(通号设计院 DS6-K5B 型),符合“故障—安全”原则。本设计所选站场为一个实际车站—** 站的上行咽喉,该站采用了 25Hz 相敏轨道电路和站内电码化设备, 道岔转换设备采用的是 S700K 型和 ZD 6 -E/J 型电动转辙机。设计内容包括两部分,一部分为设计图表,另一部分是论文,主要介绍了此次计算机联锁工程设计的原理和设计过程。主要的设计过程及内容有:车站信号平面布置图,显示有关信号设备布置情况,包括转辙机、信号机的布置等;双线轨道电路图,布置轨道电路的极性交叉以及送、受电情况;联锁表,选择基本进路以及确定敌对信号等;系统配置图, 即系统所包含的各种设备的布置情况;组合排列表,对用到的定型组合分类列表显示, 并正确排列在组合架上;信号机点灯电路图、道岔控制电路图、轨道电路图及相关的驱动、采集接口电路图。关键词:工程设计;计算机联锁系统; 接口电路; 25Hz 相敏轨道电路;站内电码化兰州交通大学毕业设计(论文) - II- Abstract At present, computer interlocking system is the most advanced interlocking system for large station, the system has large informativeness and good speed, which also is easy for operation. Computer interlocking system improved automaticity and working performance of the station, and it has broad development prospects. This time, the design puter interlocking project as the topic of the thesis, itput forward "double two out of two" mode of interlocked control(DS6-K5B Model of Beijing National Railway Research & Design Institute of Signal & Communication), which accords with the principle of fail-safe. The design chooses the up per throat of** station asa actual station, this station uses 25Hz phase - sensitive track circuit and the coding technique within the station, conversion equipment of switches adopt S700K electric switch machi nes and ZD 6 -E/J electric switch mach ines . The project includes two aspects ,one is diagram puter interlocking project design ,the other is the dissertation mainly account for the design ’s principle and process puter interlocking project. The concrete design process and the content are: Signal plane arrangement diagram , which is about signal equipment ’s arrangement , and includes arrangements about point switches , signal machines and soon. Double line track circuit diagram, which is arranged track circuit ’s polar reversal and receive end and feed end's arrangement situation. Chain
