步骤S104:判断列车是否位于中间站,且处于未发车状态,如果是,执行步骤S105;
在本步骤中,列车运行在首发站和终点站之间时,可以完全由自动驾驶系统控制。
所述中间站指的是列车运行路线中除去首发站和终点站之外的其他站点,在车辆进入中间站或终点站时,自动驾驶系统通过定位应答器对列车的位置进行校正,以获取列车的当前位置,并根据列车当前位置和速度不断调整输出的制动等级,以控制列车准确地在车站股道停车标处停车,其中,输出的制动等级不同向列车施加的制动的力不同。当列车完全制动后,列车处于停车状态,等待一定时间后,才可驶离车站,在驶离车站之前,列车一直处于未发车状态。
步骤S105:判断列车是否处于自动驾驶模式,当判断结果为是时,执行步骤S106;
列车在中间车站停车时,可能处于手动驾驶状态或处于自动驾驶状态,本申请主要针对自动驾驶状态时的操控过程进行介绍。
步骤S106:当列车具备发车条件,并且当所述ATO启动按钮被触发时,通过自动驾驶模式控制列车发车。
在本申请实施例公开的技术方案中,由于车辆在发车时存在各种状况,为了保证乘客和工作人员的安全,在列车驶出中间站时需要人工干预,只有列车司机触发所述ATO启动按钮后,自动驾驶系统才可控制列车驶离中间站。
其中,在判断列车是否具备发车条件时,这些发车条件可以由用户自行设定,例如,所有车门是否全部关闭等,当具备发车条件后,向列车司机输出触发信号,以提示司机可以发车。
通过本申请上述实施例公开的技术方案可见,上述方案通过判断列车是否符合自动驾驶条件,如果是,且当检测到司机操纵平台上的ATO启动按钮被触发时,控制列车进入自动驾驶模式;在列车需要驶离中间站时,当列车位于中间站、处于未发车状态,且处于自动驾驶模式时,并且当所述ATO启动按钮被触发时,通过自动驾驶模式控制列车发车。通过上述方式可以实现列车进入自动驾驶模式,并且,通过人工干预列车驶离中间站的方式,保证了列车的安全运行。
进一步的,在本申请实施例公开的技术方案中,所述自动驾驶条件所包含的内容可以依据用户需求自行设定,例如,当列车处于完全监控模式、方向手柄向前、司控器手柄零位、ATO设备工作正常、ATP设备未输出紧 急制动,且动车组状态满足允许ATO模式的条件时,列车方可进入自动驾驶模式,对此,在本申请实施例公开的技术方案中,所述判断列车是否符合自动驾驶条件,可以包括:
判断所述列车是否处于完全监控模式;
判断所述列车的方向手柄是否向前;
判断所述列车的司机控制器手柄是否处于零位;
判断所述列车的自动驾驶系统是否正常工作;
判断所述列车的自动保护系统是否输出紧急制动信号;
当所述列车处于完全监控模式、方向手柄向前、司机控制器手柄处于零位、自动驾驶系统正常工作、且自动保护系统没有输出紧急制动信号时,表明列车符合自动驾驶条件。
本申请实施例公开的技术方案除了可以控制列车进入自动驾驶模式之外,还可以控制列车退出自动驾驶模式,具体的,上述方法还可以包括:判断列车是否符合退出自动驾驶条件,如果是,控制列车退出自动驾驶模式。
所述退出自动驾驶条件,可以包括以下任意一种情况,即以下任意一种情况发生时,列车退出自动驾驶模式:
所述列车的编组列车中有两个或两个以上的牵引被切除;
所述列车的编组列车中至少有一个编组列车的空气制动不可用;
所述列车处于限速保护状态;
所述列车处于常用制动状态;
所述列车处于紧急制动状态;
所述列车处于保持制动被隔离的状态;
所述列车与自动驾驶系统之间的通信失效。
此外,本申请还对所述自动驾驶系统的控制过程进行了进一步说明,具体的,其控制过程可以包括如下几个方面:
区间自动运行:当列车进入自动驾驶模式时,列车网络系统会采集自动驾驶系统的有效信号,当采集信号为有效时,列车牵引控制系统和制动控制系统分别执行自动驾驶系统发送的牵引、制动控制指令;列车首先判断自动驾驶系统的“牵引/制动命令状态标志”信号,当标志状态为牵引时, 列车网络系统将相应字段命令信息发送至列车牵引控制系统,牵引控制系统执行相应的牵引控制量;当标志状态为制动时,列车网络系统将相应字段命令信息发送至列车制动控制系统,制动控制系统执行相应的制动控制量。网络系统与牵引、制动控制系统配合,执行自动驾驶系统的控制命令,完成列车在区间的自动运行,此过程不需要司机操作司控器手柄。
车站自动停车:自动驾驶通过精确定位应答器进行位置校正,并根据列车当前位置和速度不断调整输出的制动等级,控制列车准确地在车站股道停车标处停车。
当列车停稳停准后,网络系统将自动控制设备的“保持制动指令”发送至制动控制系统,在施加保持制动时,制动控制系统响应列控系统输出的最高级位制动。车辆网络系统判断满足保持制动缓解的条件时,会自动缓解保持制动。
列车换端:当列车换段时,退出自动驾驶模式,此时保持制动的施加由车辆接管。
车门开门防护:当列车停准且停稳,列控系统地面设备向车载设备发送站台侧信息,由列车保护系统(ATP)根据站台侧信息输出相应的开门允许指令,列车通过硬线控制电路将ATP系统输出的门释放信号叠加到现有车辆门释放硬线控制信号,并增设切换开关对门释放由司机还是ATP系统输出进行选择切换,即,当所述切换开关处于第一状态时,门释放由司机通过操作平台上的按钮进行控制,当当所述切换开关处于第二状态时,门释放由所述ATP系统自动控制;同时,列车网络系统采集ATP系统输出的开门允许信号点亮相应的“门释放”指示灯。当所述“门释放”指示灯被点亮以后,所述自动驾驶系统通过列车行驶方向和当前站点,确定开门信号,所述开门信号用于表征开左门还是开右门,并且所述自动驾驶系统通过继电器干节点将开门信号叠加到现有列车的开门硬线控制信号,在所述开门信和所述门释放信号的共同作用下实现“开左门”或“开右门”功能。网络系统将切换开关的状态发送至门控器,当切换开关置于第二状态时,门控器屏蔽本地开门功能,即,司机无法在操作平台控制门的开启和关闭,保证乘客无法在本地打开车门进而保证乘客安全。
车门/站台门联动控制:车门/站台门的开门联动控制由司机或自动驾驶 设备触发,关门联动控制由司机触发。由于地面信号的传输距离较长,为保证车门/站台门可以同步的打开和关闭,列车的门控器增加延时。
