具体实施方式
下面将结合本申请实施例中的附图,对本申请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申请一部分实施例, 而不是全部实施例。基于本申请中的实施例,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,都属于本申请保护范围。
本申请提供的空电联合制动控制系统主要应用于城市轨道列车,主要实现的是空电联合制动效果。空电联合制动是通过电制动与空气制动结合,可保证列车在较大的速度范围内都有充足的制动力。而在具体实施中,电制动由于操纵控制方便,并且可以大大减少空气制动系统零部件的磨耗,因而得以优先使用。
图1为相关技术中的一种空电联合制动系统的结构图,如图1所示的结构中,切除电磁阀1设置于作用阀2前,当切除电磁阀1得电时,切除空气制动。但是该方法中,切除电磁阀1存在卡滞故障的情况,在需要恢复空气制动时,由于切除电磁阀1发生卡滞故障无法正常断开,致使空气制动无法正常施加,存在极大的行车安全隐患。
本申请的核心是提供一种列车及其空电联合制动控制系统,用以解决相关技术中在空电联合制动中由于电磁阀故障而导致无法启用空气制动进而造成行车安全隐患的问题。
为了使本技术领域的人员更好地理解本申请方案,下面结合附图和具体实施方式对本申请作进一步的详细说明。
图2为本申请实施例提供的一种空电联合制动控制系统的结构图,如图2所示,空电联合制动控制系统包括:
自动制动支路、单独制动支路、第一作用阀5、第一对比阀6;
自动制动支路包括自动制动控制支路3、第一电磁阀7;
单独制动支路包括单独制动控制支路4;
自动制动控制支路3的输入端和单独制动控制支路4的输入端均连接制动控制单元,以根据制动控制单元输出的信号导通对应的线路;
自动制动控制支路3的输出端连接第一电磁阀7,第一电磁阀7通过第一对比阀6和第一作用阀5连接;第一电磁阀7还与离合控制单元连接,以根据离合控制单元的控制指令进行状态的变换;状态包括得电状态和失电状态;若第一电磁阀7为得电状态,则列车切除空气制动,施加电制动; 若第一电磁阀7为失电状态,则列车施加空气制动;
单独制动控制支路4的输出端通过第一对比阀6和第一作用阀5连接;
第一对比阀6用于根据自动制动控制支路3的输出或单独制动控制支路4的输出对第一作用阀5进行控制以控制制动力。
本申请中提供的空电联合制动控制系统,提供了自动制动支路和单独制动支路两种控制线路,用以对空气制动进行启用和切除。本实施例中,对于空电联合制动控制系统中各部件的控制以及整体的逻辑控制是通过列车中的制动控制单元(Brake Control Unit,BCU)和离合控制单元(Clutch Control unit,CCU)进行的。
在具体实施中,自动制动控制支路3和单独制动控制支路4是制动控制单元用于配置制动模式的电路,根据制动控制单元的输出选择对应制动线路。当列车的制动模式被配置为自动制动模式时,制动控制单元的输出信号经过自动制动支路作用于第一作用阀5。由于电制动的优先性,所以需要向列车中离合控制单元申请对应空气制动力的电制动,并切除空气制动。因此自动制动支路中包括第一电磁阀7,在第一电磁阀7得电时,第一作用阀5排出制动缸(Brake Cylinder,BC)压力从而切除列车的空气制动,在第一电磁阀7失电时,则列车正常施加空气制动。其中,第一电磁阀7的得电或失电的状态转换是由离合控制单元控制的。而在具体实施中,对于第一电磁阀7的状态控制应当结合列车是否能够正常施加电制动进行调整。为此在本实施例中,在制动控制单元通过自动制动支路施加制动时,离合控制单元还用于判断电制动是否可用。若可用,则控制第一电磁阀7得电;若不可用,则保持第一电磁阀7失电。
可以理解的是,本实施例中,电磁阀仅存在于自动制动支路中,因此离合控制单元通过控制第一电磁阀7的得失电实现对空气制动的切除和启用。而在单独制动支路中,制动控制单元通过单独制动控制支路4作用于第一作用阀5,不受第一电磁阀7影响,在第一电磁阀7故障时仍能保持列车的制动,提高了行车安全。
本实施例中的自动制动控制支路和单独制动控制支路为制动控制单元施加信号至作用阀的连接线路,该线路结构可以与当前技术中的制动控制 单元与作用阀的连接线路相似,本实施例中不做过多描述。
本申请所提供的空电联合制动控制系统,包括自动制动支路、单独制动支路、第一作用阀、第一对比阀;自动制动支路包括自动制动控制支路、第一电磁阀;单独制动支路包括单独制动控制支路。本申请中,列车的制动模式分为自动制动和单独制动,通过制动控制单元的输出选择对应的制动支路,施加不同的制动模式。本申请中的自动制动支路中包括第一电磁阀,第一电磁阀作用于第一作用阀,以在电磁阀得电时切断空气制动,以实现电制动的优先性。为了避免电磁阀卡滞而不能恢复空气制动的情况,本申请还提供了单独制动的模式。在单独制动支路中不包括电磁阀,制动控制单元通过单独制动控制支路作用于第一作用阀。因此电磁阀的得失电情况不会影响单独制动的制动效果。
相对于相关技术中,电磁阀设置于作用阀前,通过电磁阀的得失电控制空气制动的启用和切除。本技术方案中,提供自动制动和单独制动两种制动路径,在自动制动控制支路中提供第一电磁阀,用于切除空气制动,实现电制动的优先制动。在电磁阀故障后,可以选用单独制动支路进行空气制动,从而实现了制动的备份,保证了行车安全。
可以理解的是,对于空电联合制动的列车,当制动缸中的制动气压过高时,会导致制动缸内部件无法承受高压导致损坏,也会造成在刹车的时候,出现突然刹车或者制动力的突然增加,导致车轮出现报死和产生甩尾的情况。因此即使电制动具有优先性,在制动缸内气压过高时应当优先施加空气制动,避免造成部件的损坏。
为此,在上述实施例的基础上,本实施例中,单独制动支路还包括第一压力传感器8;第一压力传感器8与制动控制单元连接,设置于制动缸处,用于采集制动缸内的压力并发送至制动控制单元;
制动控制单元用于在单独制动支路输出时,在第一压力传感器8采集的压力达到预设压力时,切除电制动,施加空气制动;在第一压力传感器8采集的压力小于预设压力时,根据制动控制单元的信号施加空气制动或电制动。
可以理解的是,本实施例的目的是在电制动优先性的前提下,施加空气制动实现制动效果,释放制动缸内压力,而本申请中的单独制动支路中无法实现空气制动的切断,因此第一压力传感器设置在单独制动支路中,以在采集的压力达到预设压力时,切除电制动,施加空气制动。而在压力没有达到预设压力,列车可以根据制动控制单元的信号正常施加空气制动或电制动,从而实现了对制动缸内部件的保护,避免制动缸内压力过高导致刹车时制动力的突然的情况。
在具体实施中,第一电磁阀7由于使用环境以及使用时长的影响,存在卡滞故障或者不受离合控制单元控制的情况。在列车为自动制动模式时,如果第一电磁阀7故障则会影响制动效果,造成行车安全隐患。
为了及时的查看第一电磁阀7是否故障,是否危害行车安全,本实施例中,自动制动支路还包括第二压力传感器9;第二压力传感器9与制动控制单元连接,设置于制动缸处,用于采集制动缸内的压力并发送至制动控制单元;制动控制单元用于在第一电磁阀7得电时,判断制动缸内的压力是否为0以确认第一电磁阀7是否正常;或者在第一电磁阀7失电时,判断制动缸内的压力是否不为0以确认第一电磁阀7是否正常。
本实施例中,对于第一电磁阀是否故障的判断是通过其是否能够正常对第一作用阀进行控制进行验证的。可以理解的是,第一电磁阀切除空气制动的原理是在第一电磁阀得电时,作用阀释放制动缸内压力,从而列车无法施加空气制动,此时制动缸内的压力应为0。而在第一电磁阀失电时,制动缸内的压力应当不为0,列车能够正常进行空气制动。因此,本实施例中通过增加第二压力传感器,通过在第一电磁阀得失电时,检测制动缸内压力是否为0进而确认第一电磁阀是否故障。
通过上述实施例的介绍可以理解的是,当列车的制动模式为自动制动时,如果第一电磁阀7发生故障无法恢复空气制动时,只能通过单独制动实现制动效果。为此,本实施例中还包括:切除联锁塞门10;
自动制动控制支路3的第一输出端通过切除联锁塞门10和第一电磁阀 7连接,第二输出端通过切除联锁塞门10与第一对比阀6连接;
切除联锁塞门10还与离合控制单元连接,以根据离合控制单元的指令切除第一电磁阀7对第一作用阀5的控制。
在本实施例中,切除联锁塞门起到将第一电磁阀隔离的作用,切除联锁塞门受离合控制单元控制,在正常情况下,自动制动控制支路的输出经过第一电磁阀施加至作用阀,当第一电磁阀故障时,离合控制单元控制切除联锁塞门断开自动制动控制支路与第一电磁阀的连接,将自动制动控制支路连接至第一对比阀,从而切除了第一电磁阀对第一作用阀的控制,对此,自动制动中仍保留了空气制动的制动方式,提高了行车安全。
在具体实施中,为了增加行车安全性,避免突发情况而不能及时的制动进而产生位线。在上述实施例的基础上,在本实施例中还包括:
紧急制动电路;紧急制动电路连接制动控制单元,以在第一电磁阀7故障时施加紧急制动。
本实施例中还提供了一种具体的紧急制动电路,如图2所示,紧急制动电路包括:第二作用阀11、第二电磁阀12、调压阀;
调节阀13用于配置第二作用阀11对制动力的大小控制,调节阀13通过第二电磁阀12与第二作用阀11连接,第二电磁阀12还与离合控制单元连接,以在得电时导通紧急制动电路,施加紧急制动。
在本实施例中,紧急制动是在第一电磁阀7故障,影响制动效果时施加的制动,可以理解的是,由于本申请在上述实施例中提供了单独制动模式以及切除联锁塞门10的使用,在第一电磁阀7故障时,列车仍可通过其他方式实现制动。为此,为了避免突然施加紧急制动对行车造成影响,在第一电磁阀7故障后可以发送信息至显示器上,以提醒驾驶人员,并接收驾驶人员的确认指令,以确认是否进行紧急制动。
在本实施例中,制动控制单元还用于在通过自动制动支路施加制动时,在检测到第一电磁阀7故障的情况下,发送提示信息并接收确认指令;若在预设时间内接收到确认指令,则离合控制单元控制切除联锁塞门10隔离第一电磁阀7;若在预设时间内未接收到确认指令,则离合控制单元控制 第二电磁阀12得电进行紧急制动。
本实施例中,当第一电磁阀7发生故障后,制动控制单元通过显示器、触摸屏等人机交互设备显示提示信息,以使驾驶人员知悉第一电磁阀7的故障情况,当驾驶人员收到确认信息后,则列车中离合控制单元控制切除联锁塞门10隔离第一电磁阀7,从而切除第一电磁阀7对第一作用阀5的影响,使列车可以施加空气制动。当驾驶人员没有收到确认信息时,则列车施加紧急制动,避免行车危险。本实施例中还增加了驾驶人员接收确认信息的时间限制,若在规定时间内驾驶人员没有确认收到了提示信息,则施加紧急制动。
在上述实施例的基础上,在本实施例中,还包括第二对比阀14;第二对比阀14的第一端连接第一作用阀5,第二端连接第二作用阀11;第二对比阀14的输出端连接制动缸,以根据第二对比阀14的输出大小确认列车的制动是否为紧急制动。
本实施例中的第二对比阀,用于根据第二作用阀的输出确认列车施加的制动是否为紧急制动。可以理解的是,紧急制动模式的作用是在行车危险时及时的停车,避免突发情况。在行车过程中,列车施加的制动可能为自动制动模式或单独制动模式中的制动,或者紧急制动。而可以理解的是,紧急制动模式时为了使列车尽快停下,施加的制动力与正常行驶中施加的制动力大小不同,通过调节阀配置紧急制动时的制动力大小,当列车正常通过第一作用阀施加制动时,与紧急制动时通过第二作用阀施加制动时的制动力大小不同,因此通过第二对比阀比较第一作用阀和第二作用阀的输出即可实现对制动模式的判断。
此外,本实施例中还提供一种列车,包括车辆本体以及上述实施例中提供的空电联合制动控制系统。
本申请所提供的列车包括空电联合制动控制系统,空电联合制动控制系统包括自动制动支路、单独制动支路、第一作用阀、第一对比阀;自动制动支路包括自动制动控制支路、第一电磁阀;单独制动支路包括单独制动控制支路。本申请中,列车的制动模式分为自动制动和单独制动,通过 制动控制单元的输出选择对应的制动支路,施加不同的制动模式。本申请中的自动制动支路中包括第一电磁阀,第一电磁阀作用于第一作用阀,以在电磁阀得电时切断空气制动,以实现电制动的优先性。为了避免电磁阀卡滞而不能恢复空气制动的情况,本申请还提供了单独制动的模式。在单独制动支路中不包括电磁阀,制动控制单元通过单独制动控制支路作用于第一作用阀。因此电磁阀的得失电情况不会影响单独制动的制动效果。相对于相关技术中,电磁阀设置于作用阀前,通过电磁阀的得失电控制空气制动的启用和切除。本技术方案中,提供自动制动和单独制动两种制动路径,在自动制动控制支路中提供第一电磁阀,用于切除空气制动,实现电制动的优先制动。在电磁阀故障后,可以选用单独制动支路进行空气制动,从而实现了制动的备份,保证了行车安全。
