一种适用于城轨地铁车辆故障导向安全的警惕控制电路 技术领域
本发明涉及城轨地铁车辆技术领域，具体涉及一种适用于城轨地铁车辆故障导向安全的警惕控制电路。
背景技术
城轨地铁车辆的警惕控制电路是整车控制逻辑的重要组成部分之一。其属于城轨地铁司机操作项点中必须熟练掌握的车辆控制逻辑和操作技能。警惕逻辑的功能定义为在车辆运行过程中防止司机因某种原因(如睡着手离开司控器、车辆运行时离开司机室等情况)离开司控器手柄，而对整车运行设置的保障性功能逻辑，包括通过TCMS记录司机操作情况、离开手柄后，触发蜂鸣提醒和触发紧急制动等。
目前城轨地铁车辆的警惕控制电路相对简单，附加实用的功能很少，仅满足基本的车辆运行和司机操作要求。以国内某条成功运营多年的地铁车辆为例，该警惕控制电路如图1所示，上述的警惕控制电路从设计上是基本满足车辆正常的工作需要的，但是存在以下缺点：
警惕电路的线路或者电路中的某一设备故障断开，此时警惕保护功能失效，无法触发紧急制动。
发明内容
针对现有技术所存在的上述缺点，本发明在于提供一种适用于城轨地铁车辆故障导向安全的警惕控制电路，本发明优化了现有警惕控制逻辑和消除存在的短板，使得警惕功能得到极大的灵活运用。在满足车辆运行的同时，极大限度的保证车辆运行安全。
为实现上述目的，本发明提供了如下技术方案：
一种适用于城轨地铁车辆故障导向安全的警惕控制电路，所述的警惕控制电路能够有效的解决警惕电路线路或者电路中的某一设备故障断开，此时警惕保护功能失效，无法触发紧急制动的问题；
所述的警惕控制电路包括司机控制器主手柄警惕开关，所述司机控制器主手柄警惕开关的一端连接有第二操纵台二极管端子排CDT，且司机控制器主手柄警惕开关的另一端连接有零速继电器、第二断电延时动作警惕继电器触点和第四断电延时动作警惕继电器触点，所述零速继电器的另一端连接有警惕测试按钮，所述警惕测试按钮远离零速继电器的一端与第二操纵台二极管端子排CDT相连，所述警惕测试按钮远离零速继电器的一端连接有第一断电延时动作警惕继电器，所述第二断电延时动作警惕继电器触点的一端连接有第三断电延时动作警惕继电器。

本发明进一步设置为：所述第一操纵台二极管端子排CDT远离司机控制器主手柄警惕开关的一端连接司控器。
本发明进一步设置为：所述司机控制器主手柄警惕开关、零速继电器、第二断电延时动作警惕继电器触点和第四断电延时动作警惕继电器触点的同相端均连接电源，所述电源为DC110V。

本发明进一步设置为：所述警惕控制电路采用电路防串电设计，达到预防引起错误信号的作用，其具体包括以下内容：
1)通过设置第一操纵台二极管端子排CDT，解决TCMS系统故障的情况下发生串电，导致第一断电延时动作警惕继电器常得电，进而引发警惕功能失效，而导致紧急制动不施加；
2)通过设置第二操纵台二极管端子排CDT，解决车辆静止时，零速继电器闭合，而此时警惕测试按钮闭合，由于该电路连接至DC110V母线从而导通，将电信号发送至TCMS系统，导致TCMS系统接收到司机控制器主手柄警惕开关被按下的错误信号，从而导致TCMS系统误判。
本发明进一步设置为：设计以下安全测试功能：当在车辆静止时，由于司机控制器主手柄警惕开关处于失效状态，无法判断警惕电路是否正常工作，所以设置警惕测试按钮，通过断开警惕测试按钮，测试警惕电路是否正常工作，便于发车前进行测试，保证车辆安全运行。
本发明进一步设置为：设计以下测试电路：在车辆静止时，所述零速继电器触点和警惕测试按钮同时闭合，司机控制器主手柄警惕开关处于断开状态，第一断电延时动作警惕继电器处于常得电状态，无 法进行警惕控制电路功能测试，通过按压警惕测试按钮断开第一断电延时动作警惕继电器供电，模拟车辆运行状态可对警惕控制电路功能进行测试，警惕测试功能适用于发车前准备和日常车辆维护的情况使用。
本发明进一步设置为：所述警惕控制电路任意一点发生断路或短路，会触发警惕蜂鸣器报警，进而触发紧急制动。
有益效果
采用本发明提供的技术方案，与已知的公有技术相比，具有如下有益效果：
本发明在司机离开司控器主手柄时，断电延时第一断电延时动作警惕继电器和第三断电延时动作警惕继电器相继延时动作，3s后触发警惕蜂鸣器报警，再过3s后触发紧急制动。当出现断路或短路故障时，第一断电延时动作警惕继电器和第三断电延时动作警惕继电器相继延时动作，3s后触发警惕蜂鸣器然后再触发紧急制动，使得车辆安全受到极大的保护，满足车辆运行的同时，极大限度的保证车辆运行安全，优化了现有警惕控制逻辑和消除存在的短板，使得警惕功能得到极大的灵活运用，能够有效的解决警惕电路线路或者在电路中的某一设备故障断开，使得警惕功能无法起到保护作用时，并且司机人员同时发生某种原因离开司控器手柄，此时警惕保护功能失效，无法触发紧急制动的问题。

具体实施方式
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。
在本发明的描述中，需要说明的是，术语“上”、“下”、“内”、“外”、“顶/底端”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本发明和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性。

实施例1：
为了对本发明的电路优有益效果进行更好的说明，以现有国内某条成功运营多年的地铁车辆为例，该警惕控制电路图如图1所示。
该警惕电路仅在激活司机室独立形成逻辑回路，具体控制逻辑和操作是：
(1)车辆处于蓄电池激活、操作端激活后，在静止状态下，由于“零速”继电器ZVR得电，其常开触点闭合，使得警惕继电器DMAR线圈得电，其两个常闭触点断开，使得电延时动作警惕继电器DMTDR1和DMTDR2不得电，截断了后续控制逻辑。该状态相当于旁路了司机通过操作司控器主手柄DMC来触发警惕功能，使得司机在发车前可以释放双手，做好发车前的准备工作。
(2)同样的旁路功能还有在ATO场景、ATB折返场景、操作DMBB旁路按钮等情况下，同样能起到旁路警惕功能作用。
在非信号系统控车(如ATP)情况下，车辆运行过程中，司机必须按压司控器主手柄DMC来维持警惕控制电路。司机一旦离开手柄位置，继电器DMAR就失电，其常闭触点闭合，进而使得延时动作警惕继电器DMTDR1和DMTDR2开始得电计时，如果时间超过3秒(可调整) 就发出警惕蜂鸣，提醒司机操作司控器主手柄DMC来维持警惕控制，司机操作后蜂鸣消失，车辆运行正常；当蜂鸣报警超过2秒(可调整)后，DMTDR2延时断开常闭触点，使得紧急制动安全环线失电，直接触发紧急制动(车辆认为司机已经不具备控车条件)。
该电路存在的问题：警惕电路线路或者在电路中的某一设备故障断开，使得警惕功能无法起到保护作用时，此时警惕保护功能失效，无法触发紧急制动的问题。
实施例2：
请参照图2所示，本发明提供了一种适用于城轨地铁车辆故障导向安全的警惕控制电路；
警惕控制电路能够有效的解决警惕电路线路或者在电路中的某一设备故障断开，此时警惕保护功能失效，无法触发紧急制动的问题；
警惕控制电路包括司机控制器主手柄警惕开关1，司机控制器主手柄警惕开关1的一端连接有第二操纵台二极管端子排CDT3，且司机控制器主手柄警惕开关1的另一端连接有零速继电器4、第二断电延时动作警惕继电器触点7和第四断电延时动作警惕继电器触点9，零速继电器4的另一端连接有警惕测试按钮5，警惕测试按钮5远离零速继电器4的一端与第二操纵台二极管端子排CDT3相连，警惕测试按钮5远离零速继电器4的一端连接有第一断电延时动作警惕继电器6，第二断电延时动作警惕继电器触点7的一端连接有第三断电延时动作警惕继电器8。
还包括第一操纵台二极管端子排CDT2，第一操纵台二极管端子 排CDT2的一端与司机控制器主手柄警惕开关1和第二操纵台二极管端子排CDT3的连接端相连接，本发明通过设置司控器DMS动作TCMS监控逻辑，将TCMS监控司机操作状态，作为时间记录和数据分析。
第一操纵台二极管端子排CDT2远离司机控制器主手柄警惕开关1的一端连接司控器；司机控制器主手柄警惕开关1、零速继电器4、第二断电延时动作警惕继电器触点7和第四断电延时动作警惕继电器触点9的同相端均连接电源，电源为DC110V；第四断电延时动作警惕继电器触点9远离司机控制器主手柄警惕开关1的一端连接有警惕蜂鸣器10，警惕蜂鸣器10的另一端接地；第一断电延时动作警惕继电器6远离警惕测试按钮5的一端接地，第三断电延时动作警惕继电器8远离第二断电延时动作警惕继电器触点7的一端接地，本发明将第一断电延时动作警惕继电器6、第二断电延时动作警惕继电器触点7、第三断电延时动作警惕继电器8和第四断电延时动作警惕继电器触点9运用在逻辑电路中，不仅对司机人员操作行为进行监控，还对整个逻辑电路发生断路、短路异常时，触发报警和紧急制动，起到故障导向安全作用。
本发明采用电路防串电设计，达到预防引起错误信号的作用，其具体包括以下内容：
1)通过设置第一操纵台二极管端子排CDT2，解决TCMS系统故障的情况下发生串电，导致第一断电延时动作警惕继电器6常得电，进而引发警惕功能失效，而导致紧急制动不施加；
2)通过设置第二操纵台二极管端子排CDT3，解决车辆静止时， 零速继电器4闭合，而此时警惕测试按钮5闭合，由于该电路连接至DC110V母线从而导通，将电信号发送至TCMS系统，导致TCMS系统接收到司机控制器主手柄警惕开关1被按下的错误信号，从而导致TCMS系统误判。
设计以下安全测试功能：当在车辆静止时，由于司机控制器主手柄警惕开关1处于失效状态，无法判断警惕电路是否正常工作，所以设置警惕测试按钮5，通过断开警惕测试按钮5，测试警惕电路是否正常工作，便于发车前进行测试，保证车辆安全运行。
设计以下测试电路：在车辆静止时，零速继电器4触点和警惕测试按钮5同时闭合，司机控制器主手柄警惕开关1处于断开状态，第一断电延时动作警惕继电器6处于常得电状态，无法进行警惕控制电路功能测试，通过按压警惕测试按钮5断开第一断电延时动作警惕继电器6供电，模拟车辆运行状态可对警惕控制电路功能进行测试，警惕测试功能适用于发车前准备和日常车辆维护的情况使用。
此外，本发明警惕控制电路任意一点发生断路或短路，会触发警惕蜂鸣器10报警，进而触发紧急制动。
作为一种实施方式，在司机离开司控器主手柄时，断电延时第一断电延时动作警惕继电器6和第三断电延时动作警惕继电器8相继延时动作，3s后触发警惕蜂鸣器10报警，再过3s后触发紧急制动；当出现线路断路或短路故障时，第一断电延时动作警惕继电器6和第三断电延时动作警惕继电器8相继延时动作，3s后触发警惕蜂鸣器10然后触发紧急制动；使得车辆安全受到极大的保护(故障导向安 全)，满足车辆运行的同时，极大限度的保证车辆运行安全。
本发明的各部分可以用硬件、软件、固件或他们的组合来实现，在上述实施方式中，多个步骤或方法可以用存储在存储器中且由合适的指令执行系统执行的软件或固件来实现，例如，如果用硬件来实现，和在另一实施方式中一样，可用本领域公知的下列技术中的任一项或他们的组合来实现：具有用于对数据信号实现逻辑功能的逻辑门电路的离散逻辑电路，具有合适的组合逻辑门电路的专用集成电路，可编程门阵列(PGA)，现场可编程门阵列(FPGA)等。
以上实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不会使相应技术方案的本质脱离本发明各实施例技术方案的精神和范围。

    所述的警惕控制电路包括司机控制器主手柄警惕开关(1)，所述司机控制器主手柄警惕开关(1)的一端连接有第二操纵台二极管端子排CDT(3)，且司机控制器主手柄警惕开关(1)的另一端连接有零速继电器(4)、第二断电延时动作警惕继电器触点(7)和第四断电延时动作警惕继电器触点(9)，所述零速继电器(4)的另一端连接有警惕测试按钮(5)，所述警惕测试按钮(5)远离零速继电器(4)的一端与第二操纵台二极管端子排CDT(3)相连，所述警惕测试按钮(5)远离零速继电器(4)的一端连接有第一断电延时动作警惕继电器(6)，所述第二断电延时动作警惕继电器触点(7)的一端连接有第三断电延时动作警惕继电器(8)。
  2. 根据权利要求1所述的一种适用于城轨地铁车辆故障导向安全的警惕控制电路，其特征在于，还包括第一操纵台二极管端子排CDT(2)，所述第一操纵台二极管端子排CDT(2)的一端与司机控制器主手柄警惕开关(1)和第二操纵台二极管端子排CDT(3)的连接端相连接。
  3. 根据权利要求2所述的一种适用于城轨地铁车辆故障导向安全的警惕控制电路，其特征在于，所述第一操纵台二极管端子排CDT(2)远离司机控制器主手柄警惕开关(1)的一端连接司控器。
  4. 根据权利要求1所述的一种适用于城轨地铁车辆故障导向安全的警惕控制电路，其特征在于，所述司机控制器主手柄警惕开关(1)、零速继电器(4)、第二断电延时动作警惕继电器触点(7)和第四断电延时动作警惕继电器触点(9)的同相端均连接电源，所述电源为DC110V。
  5. 根据权利要求1所述的一种适用于城轨地铁车辆故障导向安全的警惕控制电路，其特征在于，所述第四断电延时动作警惕继电器触点(9)远离司机控制器主手柄警惕开关(1)的一端连接有警惕蜂鸣器(10)，所述警惕蜂鸣器(10)的另一端接地。
  6. 根据权利要求1所述的一种适用于城轨地铁车辆故障导向安全的警惕控制电路，其特征在于，所述第一断电延时动作警惕继电器(6)远离警惕测试按钮(5)的一端接地，所述第三断电延时动作警惕继电器(8)远离第二断电延时动作警惕继电器触点(7)的一端接地。
  7. 根据权利要求2所述的一种适用于城轨地铁车辆故障导向安全的警惕控制电路，其特征在于，所述警惕控制电路采用电路防串电设计，达到预防引起错误信号的作用，其具体包括以下内容：
    1)通过设置第一操纵台二极管端子排CDT(2)，解决TCMS系统故障的情况下发生串电，导致第一断电延时动作警惕继电器(6)错误动作，进而引发电路动作，引起误报警，而导致紧急制动；
    2)通过设置第二操纵台二极管端子排CDT(3)，解决车辆静止时，零速继电器(4)闭合，而此时警惕测试按钮(5)闭合，由于该 电路连接至DC110V母线从而导通，将电信号发送至TCMS系统，导致TCMS系统接收到司机控制器主手柄警惕开关(1)被按下的错误信号，从而导致TCMS系统误判。
  8. 根据权利要求1所述的一种适用于城轨地铁车辆故障导向安全的警惕控制电路，其特征在于，设计以下安全测试功能：当在车辆静止时，由于司机控制器主手柄警惕开关(1)处于失效状态，无法判断警惕电路是否正常工作，所以设置警惕测试按钮(5)，通过断开警惕测试按钮(5)，测试警惕电路是否正常工作，便于发车前进行测试，保证车辆安全运行。
  9. 根据权利要求1所述的一种适用于城轨地铁车辆故障导向安全的警惕控制电路，其特征在于，设计以下测试电路：在车辆静止时，所述零速继电器(4)触点和警惕测试按钮(5)同时闭合，司机控制器主手柄警惕开关(1)处于断开状态，第一断电延时动作警惕继电器(6)处于常得电状态，无法进行警惕控制电路功能测试，通过按压警惕测试按钮(5)断开第一断电延时动作警惕继电器(6)供电，模拟车辆运行状态可对警惕控制电路功能进行测试，警惕测试功能适用于发车前准备和日常车辆维护的情况使用。
  10. 根据权利要求5所述的一种适用于城轨地铁车辆故障导向安全的警惕控制电路，其特征在于，所述警惕控制电路任意一点发生断路或短路，会触发警惕蜂鸣器(10)报警，进而触发紧急制动。
