 有益效果
实施本发明的技术方案，不但可以降低故障率、提高使用寿命，使得性能更加稳定；而且，不再需要专业技术人员定期到现场进行检测，大大减少了技术人员配置，提高了工作效率，且消除了人为因素的安全隐患。
 附图说明
图1是本发明铁路信号灯的点灯监测控制装置实施例一的逻辑结构图；
图2A至图2G为本发明铁路信号灯的点灯监测控制装置实施例二的电路图。
 本发明的实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
图1是本发明铁路信号灯的点灯监测控制装置实施例一的逻辑结构图，点灯监测控制装置与两路LED灯丝71、72相连，而且，该实施例的点灯监测控制装置包括电源模块10、切换模块20、控制模块30、以及两个整流模块41、42、两个检测模块51、52、两个恒流驱动模块61、62、两个抗干扰模块81、82。其中，整流模块41、检测模块51、恒流驱动模块61及抗干扰模块81与LED灯丝71对应，且整流模块41、恒流驱动模块51与LED灯丝71组成第一路点灯回路；整流模块42、检测模块52、恒流驱动模块62及抗干扰模块82与LED灯丝72对应，且整流模块42、恒流驱动模块52与LED灯丝72组成第二路点灯回路。
在该实施例中，整流模块41、42用于在接入电源模块10时，对电源模块10的输出电压进行转换，并输出至相应的恒流驱动模块61、62；恒流驱动模块61、62用于向相应LED灯丝71、72输出恒流驱动信号；检测模块51、52用于检测相应点灯回路是否故障；控制模块30用于在两路点灯回路均无故障时，进入循环工作模式；在检测到其中一路点灯回路故障时，进入单路工作模式。其中，循环工作模式为：通过切换模块20控制两个整流模块41、42周期性地交替接入电源模块10来控制两路点灯回路交替处于点亮状态；单路工作模式为：通过切换模块20控制另一点灯回路的整流模块接入电源模块10来控制另一点灯回路恒处于点亮状态，例如，假设第一点灯回路处于故障，控制模块30将会通过切换模块20控制整流模块42接入电源模块10，以使第二点灯回路恒处于点亮状态。
通过该实施例的技术方案，两个相同的点灯回路并无主副之分，而且，在两个点灯回路均无故障时，控制模块控制第一点灯回路工作一段时间后自动切换到第二点灯回路工作，第二点灯回路工作一段时间后，再自动切换到第一点灯回路，从而使两路点灯回路循环切换工作。如果其中一个点灯回路出现故障，立即切换到另一个点灯回路工作，因此，该实施例的点灯监测控制装置是智能的全自动工作状态。这样，不但可以降低故障率、提高使用寿命，使得性能更加稳定；而且，不再需要专业技术人员定期到现场进行检测，大大减少了技术人员配置，提高了工作效率，且消除了人为因素的安全隐患。
进一步地，由于铁路信号灯装设在铁道边，火车经过时，极易受电磁信号的干扰，为了消除干扰信号的影响，在每一路点灯回路里增设抗干扰模块81、82，该抗干扰模块81、82用于检测相应点灯回路是否存在干扰信号，并在存在干扰信号时，消除该干扰信号。另外，控制模块30还用于在检测到正在点亮的一路点灯回路存在干扰信号时，通过切换模块20控制另一点灯回路的整流模块接入电源模块10。
进一步地，该实施例的点灯监测控制装置还包括报警模块90，该报警模块90用于在任何一路点灯回路故障时，输出报警信号。另外，控制模块30在上电和/或切换时，还可进行自检，当自检出故障时，也会输出报警信号。
进一步地，本发明的点灯监测控制装置还包括传送模块，例如为远程智能控制端口。该传送模块用于将两路点灯回路的工作状态、检测模块的检测结果传送至远程监控室，方便监控中心随时了解产品工作状态，使系统更加智能化。

下面说明该实施例的点灯监测控制装置的工作原理：
首先，在以下任一情况下：开机、重启、准备切换点灯回路、定期，MCU U1可进行自检，确定是否正常工作，如果异常，取消循环并报警。
当MCU自检正常时，数据存储芯片U2由于预设写入有切换时间，所以可根据该切换时间（例如24小时）进入循环工作模式：控制两路点灯回路的整流模块DB1、DB2交替接入电源模块L1，从而实现两个LED灯丝交替点亮。具体地，当需要切换至第二路LED灯丝时，MCU U1的第一输出端（脚6）输出高电平，第一三极管Q1导通，第一继电器KM1的线圈上电，其动触头K3连接静触头K5，这样，便将整流模块DB2接入了电源模块L1。当需要切换至第一路LED灯丝时，MCU U1的第一输出端（脚6）输出低电平，第一三极管Q1截止，第一继电器KM1的线圈掉电，其动触头K3连接静触头K4，这样，便将整流模块DB1接入了电源模块L1。
当整流模块接入电源模块L1后，以第一路点灯回路为例，整流模块DB1将电源模块L1输出的交流电压转换成直流电压，并通过电流检测电阻RI1输出至恒流驱动芯片U3，恒流驱动芯片U3通过其脚8向第一LED灯丝输出恒流驱动信号，从而点亮该第一LED灯丝。应理解，第二路点灯回路的工作原理与第一路点灯回路相同，在此不做赘述。
在该点灯监测控制装置工作时， MCU U1还可实时检测电阻RI1、RI2的电压，并通过所检测的电压判断正在点亮的一路点灯回路是否发生开路、短路，并在发生开路或短路时，通过改变其脚6输出的电平信号来切换至另一点灯回路工作。
另外，假设当前第一点灯回路处于点亮状态，若第一点灯回路（即点亮的一路点灯回路）受到了电磁信号干扰源的影响，此时，第一点灯回路中的稳压管WE1会对干扰电压进行限制，从而使恒流驱动芯片U3有一个稳定的工作环境。同时，假如干扰电压很大，MCU U1判断其脚11端的电压变化幅度超过预设值，通过改变其脚6端的电压来切换至第二点灯回路点亮。反之，假设当前第一点灯回路处于点亮状态，若第二点灯回路（即非点亮的一路点灯回路）受到了电磁信号干扰源的影响，此时，第二点灯回路中的稳压管WE2会对干扰电压进行限制，通过合适设置元器件的参数来输入电压小于光耦U6的导通电压，光耦U6不动作，进而双向可控硅Q4不导通，因此可起到防止干扰电压传导致后面的第二LED灯丝中的作用，避免了第二LED灯丝误点亮。
该点灯监测控制装置在工作过程中，如有故障，故障类型可包括：任一点灯回路开路/短路（例如， LED灯丝故障、恒流驱动模块故障、切换模块故障）、MCU自检故障、报警模块自身故障，MCU均通过其第二输出端（脚2）输出高电平，此时，第二三极管Q2导通，第二继电器KM2的线圈上电，报警器工作，以输出报警信号。
以上所述仅为本发明的优选实施例而已，并不用于限制本发明，对于本领域的技术人员来说，本发明可以有各种更改和变化。凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的权利要求范围之内。
