Description

一种无人驾驶地铁列车的乘客报警输出控制电路 技术领域
本发明涉及全自动无人驾驶地铁车辆乘客信息系统控制，特别涉及无人驾驶地铁列车中对乘客报警输出控制方法。
背景技术
随着列车乘客信息系统的数字化程度的提高，设备之间的通信均通过总线传输，数据传输的可靠性完全取决于软件的逻辑可靠性以及稳定性。
对于乘客信息系统来讲，最关键的功能就是乘客紧急报警，在任何情况下，司机/OCC都能及时了解客室的情况，能够知道有乘客进行了呼叫报警。无人驾驶模式下，当乘客信息系统与列车网络系统(TCMS)通信故障的情况下，乘客的呼叫是无法传出来。每个车厢设置数个乘客紧急报警器(PECU)，任意车厢有乘客按下PECU的紧急按钮时，通过硬线把报警信号传给TCMS，从而保证乘客将报警信号发出。
乘客按动PECU进行呼叫OCC时，报警信号通过总线传输给客室PIS主机，由客室PIS主机将信号经过CAN/以太网总线传输到司机室PIS主机，再经过MVB接口传输给TCMS，由TCMS将呼叫信号发送到OCC。整个过程完全是基于软件去设计。因采用全自动无人驾驶，当软件出现不稳定、不可靠等情况，导致乘客报警信号不能输出，会有运营安全隐患。一旦紧急情况下，乘客的报警不能输出到TCMS，TCMS就不能将信息发送到OCC，导致OCC与乘客的联络中断，有可能会引起人员伤亡等重大事故，存在安全隐患。
在无人驾驶列车上，列车运行的安全可靠是非常重要的，并且乘客紧急对讲功能被要求要达到SIL1的安全等级认证，因此在保证系统通信可靠的前提下，要设计保留有关键功能的硬线备份，当软件运行故障的情况下，OCC人员还能及 时了解列车的情况。
发明内容
本发明的目的主要是针对上述现有技术中不足，提供一种无人驾驶地铁列车的乘客报警输出控制电路。
为了解决以上技术问题，本发明提供的无人驾驶地铁列车的乘客报警输出控制电路，所述列车安装有乘客紧急报警器，乘客紧急报警器具有报警按钮，其特征在于：还具有与报警按钮联动且一一对应的带常闭触点的报警继电器，当报警按钮被按下，报警继电器得电使其常闭触点断开，每个客室的报警继电器的常闭触点串联形成紧急报警线路，紧急报警线路两端分别接列车电源和客室的TCMS的输入/输出模块。
本发明还涉及一种无人驾驶地铁列车的乘客报警输出控制方法，使用上述乘客报警输出控制电路实现，乘客按下乘客紧急报警器的报警按钮，报警按钮联动的常闭辅助触点断开，与对应客室TCMS的输入/输出模块连接的紧急报警线路断路，TCMS检测到该断路信号确定报警发出所在客室，通知人员进行处理。
此外，本发明还涉及一种无人驾驶地铁列车，具有上述的乘客报警输出控制电路。
本发明还涉及一种无人驾驶地铁车辆，使用上述乘客报警输出控制方法对乘客报警进行处理。
在网络通信中断的情况下，通过紧急报警线路输出，仍能够将本车的报警信息输出给TCMS，从而发送到运营控制中心(OCC)使OCC及时了解客室报警情况，能保证及时派遣登乘人员解决现车问题。
乘客信息系统正常工作时，既能通过通信网络传输报警信号，也能通过硬线传输报警信号，当两者信号不一致情况下，硬线报警信号优先。当网络中断 时，硬线报警信号作为冗余，仍能够输出报警信号，大大提高了系统的可靠性。
附图说明
图1是无人驾驶地铁列车的乘客报警输出控制电路的原理图。
具体实施方式
下面结合附图对本发明的实施方式做解释说明。
无人驾驶列车，每个客室的一对门区安装1台乘客紧急报警器(PECU)，A型地铁列车是5对门，安装5个乘客紧急报警器(PECU),B型地铁列车4对门，安装4个PECU。另外在司机室逃生门附近也要安装一台PECU。
本实施例以A型地铁列车的头车为例，有五对车门和一个司机室逃生门。无人驾驶地铁列车的乘客报警输出控制电路，包括设于客室每对车门附近和司机室逃生门附近的乘客紧急报警器，每个乘客紧急报警器具有报警按钮、处理器、以及与该处理器连接的报警扬声器、摄像头、麦克风、指示灯和报警继电器(报警继电器也可设置于乘客紧急报警器外)，报警按钮具有常开触点，报警继电器具有常闭触点。报警按钮按下后，其常开触点闭合，处理器接收到信号后，驱动报警继电器动作(得电)，使报警继电器的常闭触点断开。如图1所示，本例中，头车具有六个报警按钮(5个位于客室车门处，1个位于司机室CAB逃生门处)。6个乘客紧急报警器中报警继电器的常闭触点(PEPB1、PEPB2、PEPB3、PEPB4、PEPB5、PEPB6、)串联形成紧急报警线路，紧急报警线路一端与司机室的TCMS的输入/输出模块连接；另一端经司机室右侧电气柜(CREC)的PEPBCB(紧急按钮断路器)接列车电源。对于非头车的客室，则每个客室的乘客紧急报警器中的报警继电器常闭触点串联形成紧急报警线路，与客室的TCMS的输入/输出模块连接。作为替换的方案，头车客室的5个报警继电器的常闭触点也可与客室的TCMS的输入/输出模块连接，而司机室报警继电器的常闭触点直接与司机 室TCMS的输入/输出模块连接。
本实施例中，报警继电器的常闭触点可由乘客紧急报警器内部可编程逻辑电路(FPGA)进行控制，在报警按钮按下时，按钮信号输出给FPGA电路，由FPGA电路联动控制该常闭触点断开，直到按钮被司机/OCC复位以后，FPGA电路控制常闭触点恢复闭合。
正常时，紧急报警线路是高电平有效，一旦有乘客报警，电路中断，输出低电平为报警信号。
报警按钮发出的激活信号则与处理器连接，处理器通过通信总线与客室的乘客信息系统主机通信，客室的乘客信息系统主机通过CAN总线或/和以太网总线与司机室的乘客信息系统主机连接，司机室的乘客信息系统主机通过MVB总线与TCMS通信。该部分与现有技术中的相同。
利用本实施例乘客报警输出控制电路进行乘客报警输出控制，方法如下：
乘客按下乘客紧急报警器的报警按钮，报警按钮联动的报警继电器常闭触点断开，与对应客室TCMS的输入/输出模块连接的紧急报警线路断路，TCMS检测到该断路信号确定报警发出所在客室。
乘客按下乘客紧急报警器的报警按钮，报警按钮的常开触点闭合，乘客紧急报警器将报警信号发送至客室的乘客信息系统主机，经由司机室的乘客信息系统主机再发送给TCMS，再由TCMS将报警信号发送到OCC进行报警以及显示。OCC收到信号后，可查看报警并进行摄像头录像查看，及时了解客室情况。
除上述实施例外，本发明还可以有其他实施方式。凡采用等同替换或等效变换形成的技术方案，均落在本发明要求的保护范围。
