机务股道自动化管理系统

机务段股道自动化管理系统是以计算机作为操作终端，以可编程控制器PLC为控制核心辅助安全型继电器作为采样和驱动轨旁设备，对机务段调车作业进行集中控制和信息化管理的新一代联锁系统。系统一般包括道岔集中控制子系统、作业图像监视子系统、隔离开关子系统和机车定位子系统。

道岔集中控制子系统包括室外设备和室内设备两部分。室外设备包括： 调车信号机， 道岔转辙机，轨道电路。室内设备包括：分线盘、电源屏、组合柜、控制中心柜、系统控制台、传感器柜等。该子系统能实现以下功能：选排进路、取消进路、人工解锁、进路故障解锁和区段故障解锁、道岔定（反）位操作、道岔锁闭与解锁、重复开放信号、非常关闭信号、报警及测试功能、 系统监控、 车号及检修段平面状态显示功能， 并具备远程复示，显示控制系统界面的能力。 

作业图像监视子系统主要包括红外一体摄像机、控制系统、液晶电视等，能对检修段整备场机车走行进行实时监控，为值班员操作道岔集中控制子系统提供帮助。

隔离开关子系统包含平台、隔离开关、隔开控制系统、控制室等。在分闸后，建立可靠的绝缘间隙，将需要检修的设备或线路与电源用一个明显断开点隔开，以保证检修人员和设备的安全。

机车定位子系统包括信号电缆、计轴传感器、控制柜等。用于对整备区域整备台位上的机车进行精确定位。

Track automation management system of depot is a new-generation interlocking system that carries out centralized control and information management of depot shunting operations with computer as the operating terminal, programmable logic controller (PLC) as the core, auxiliary safety relay as sampling and driving trackside equipment. The system generally consists of switch centralized control subsystem, operation image monitoring subsystem, isolation switch subsystem and locomotive positioning subsystem.

Switch centralized control subsystem is composed of outdoor equipment and indoor equipment. Outdoor equipment includes shunting signal, switch machine, and track circuit. Indoor equipment includes distribution panel, power supply panel, combination cabinet, control center cabinet, system console, and sensor cabinet. The subsystem can achieve the following functions including sorting route, cancel route, manual unlocking, route fault unlocking and section fault unlocking, normal (reverse) operation of switch, switch locking and unlocking, repeated open signal, abnormal closed signal, alarm and test functions, system monitoring, locomotive number and maintenance section plane status display. Besides, the system is provided with remote display and control system interface display.

Operation image monitoring subsystem is composed of infrared cameras, control system, and LCD TVs. It can provide real-time monitoring of the locomotive running in the overhaul section and help the attendants operate the switch centralized control subsystem.

Isolation switch subsystem is composed of platform, isolating switch, separated control system, and central control room. After opening, establish a reliable insulation gap, the need to repair the equipment or wiring and power supply with a clear disconnect points, to ensure the safety of maintenance personnel and equipment.

Locomotive positioning subsystem is composed of signal cable, axle counting sensor, and control cabinet. It is used to precisely locate the locomotive at the servicing position in servicing area.
