【摘要】：编组站是铁路网上集中办理大量货物列车到达、解体、编组出发、直通和其它列车作业的车站。其主要任务是根据列车编组计划的要求，办理货物列车的解体和编组作业。由于所有改编列车都要在编组站解体并重新编组成新的列车出发，，编组站的作业效率对整个铁路网的通过能力、作业安全、车辆周转能力等都起着重要的作用。编组站最主要的设施是驼峰场，为驼峰场提供风动道岔和风动车辆减速器所需动力风源的是驼峰空压站。驼峰空压站的自动监控是自动化驼峰一个重要的组成部分。本文以哈南四场驼峰空压站监控系统为目标，开发一套能够兼容活塞空压机和螺杆空压机，并具有自动排污功能的空压站监控系统。本系统采用两层冗余分布式结构，通过监控终端（上位机）对现地机（下位机）发送控制指令，下位机完成对相应设备的控制，当监控终端或某现地机发生故障时，不会影响其它现地机的正常运行，保证了系统的鲁棒性。本系统监控终端采用基于ARM7的硬件平台，采用基于Windows CE的EVC++编程技术实现系统软件；现地机包括现地采集控制机和排污控制机，均采用基于ARM7的硬件平台实现。系统运行结果显示，本系统可对空压机及其辅助设备进行有效监测与控制，达到了预期的效果。本文主要内容包括以下几个部分： 1.对哈南四场驼峰空压站监控系统的需求进行深入分析，确定系统体系结构和研发思路。 2.对系统现地机的功能进行详细设计，并且从硬件和软件上实现了现地采集控制机和排污控制机。 3.对监控终端的功能进行详细设计，从硬件和软件上实现了本系统监控终端。 4.详细阐述了本文开发的空压站监控系统的部署流程，以及系统部署中的注意事项。且对系统可靠性方案进行了深入分析。本系统的开发与应用，合理地利用了空压站资源，均衡空压站各设备负担，达到了节约能源、提高效率、减轻操作人员劳动强度的目的。
[Abstract]:Marshalling station is a railway network where a large number of freight trains arrive, disintegrate, set out, direct through and other train operations. Its main task is to meet the requirements of train marshalling plan. To deal with the break-up and marshalling of freight trains. As all the adapted trains have to disintegrate at the marshalling yard and reorganize into new trains, the operational efficiency of the marshalling station is safe for the passage of the entire railway network. Vehicle turnover capacity plays an important role. The main facility of the marshalling station is the hump yard. It is the hump air pressure station that provides the pneumatic switch and the pneumatic vehicle reducer for the hump yard, and the automatic monitoring of the hump air pressure station is an important part of the automatic hump. Aiming at the monitoring system of Hanan four hump air compressor station, a set of compatible piston air compressor and screw air compressor is developed in this paper. The system adopts a two-layer redundant distributed structure and sends control instructions to the ground machine (lower computer) through the monitoring terminal (upper computer). The lower computer completes the control of the corresponding equipment. When the monitoring terminal or one locale machine breaks down, it will not affect the normal operation of other locale machines. This system adopts the hardware platform based on ARM7 and the EVC programming technology based on Windows CE to realize the system software. The locale machine, including the locale acquisition control machine and the sewage control machine, is implemented on the hardware platform based on ARM7. The result of the system operation shows that the system can effectively monitor and control the air compressor and its auxiliary equipment. The expected effect has been achieved. The main contents of this article are as follows: 1. The requirements of the monitoring system for the four hump air compression stations in Hanan are analyzed in depth, and the system architecture and research and development ideas are determined. 2. The function of the system locale machine is designed in detail, and the locale acquisition control machine and the sewage control machine are realized from the hardware and software. 3. The function of the monitoring terminal is designed in detail, and the monitoring terminal is realized from the hardware and software. 4. The deployment process of the air pressure station monitoring system developed in this paper, and the matters needing attention in the system deployment are described in detail, and the reliability scheme of the system is analyzed in depth. The development and application of the system make reasonable use of the resources of the air compressor station, balance the burden of the equipment of the air compressor station, and achieve the purpose of saving energy, improving efficiency and reducing the labor intensity of the operators.
