第1章 绪 论

1.1 研究背景

铁路是国民经济的大动脉，是中国社会和经济发展的先行产业，是社会的基础设施，铁路运输部门又是国民经济中的一个重要部门，它肩负着国民经济各种物资运输的重任，对中国社会主义建设事业的发展有着举足轻重的作用。随着铁路运输的发展和科学技术的进步，保证列车行车安全的措施逐步从治理措施向技术措施过渡，直至发展到今天的自动控制系统。

车站信号设备是实现道岔、进路和信号机之间联锁关系的技术设备，用来指挥站内列车运行和调车作业，以保证车站信号行车安全，提高运输效率。随着我国铁路运输事业的发展，特别是铁路提速以来，车站信号设备发展很快，采用了许多新技术和新设备。为了保证行车安全，信号、道岔与进路之间必须以技术手段持一定的制约关系和操作顺序信号、道岔和进路之间必须有一定的制约关系，而且必须按照一定的程序才能动作和建立，只有遵循这种关系和程序才能保证列车安全运行，常称这种制约关系和操作顺序为联锁。车站联锁设备是保证站内运输作业安全、提高作业效率的铁路信号设备，它的控制对象是道岔、进路和信号机。将道岔、进路和信号机用电气方式集中控制监督，并实现它们之间联锁关系的技术方法和设备称为电气集中联锁，用继电器实现联锁关系的称为继电式电气集中联锁（简称电气集中）[1]。

6502电气集中具有电路定型化程度高、逻辑性强，操作方法简便灵活、不易出错，维修、施工比较方便，符合故障—安全原则，易于区间闭塞设备及其他信号设备集合等优点,又是调度集中和调度监督的基本设备，因此在我国铁路得到了广泛的应用。随着铁路运输的发展需要和科学技术的进步，保证行车安全的措施逐步从管理措施向技术措施过渡，直至发展成今天的自动控制系统。6502电气集中联锁设备作为实现控制车站范围内的道岔、进路和信号机，并实现它们的联锁，有着保证行车安全、缩短列车停站时间、提高铁路运输效率、改善行车人员的作业条件、提高车站通过能力等等优点，是一种高效、安全、经济的车站连锁设备。随着我国铁路运输生产的不断发展,全路信号设备不断地得到改善。要大力发展铁路运输,保证行车安全,提高运输效率,就必须在信号设备方面加大投人,大幅度地提高信号设备的装备数量和技术水平。目前6502电气集中作为一种较为先进的信号设备,在全路已经相当普及,而且,6502电气集中也确实在铁路运输中发挥了越来越重要的作用。它不论从电路结构上,还是从
