Description

一种接车进路信息、发车进路信息的传输方法及系统 技术领域
本发明属于轨道交通技术领域，特别涉及一种接车进路信息、发车进路信息的传输方法及系统。
背景技术
由于车站各条进路的列车运行所需线路基础数据不同、临时限速不同、各条进路的长度也不同，车载设备控制列车进入车站时，需通过列车将要运行的实际进路信息获得对应进路的线路基础数据、临时限速等，以满足车载设备控制列车安全运行的需求。同时列车由站内进入区间时，由于可能有多条区间线路，每条线路对应的区间线路基础数据、临时限速、闭塞分区位置、信号机位置等均不相同，故列车在进入区间前必须知道其将要进入的区间准确数据，用于控制列车在区间安全运行。
本方法主要依托轨道电路的编码(轨道电路低频信息)，在进站信号机(进路信号机)内方或特定轨道区段，以及发车进路最后一个区段为列车提供接车进路信息及对应发车口信息。
现有的CTCS-2级列控系统中采用设置在进站信号机外方的有源应答器为列车提供接车进路信息及接车进路基础数据、临时限速等信息；通过设置在反向进站信号机外方的有源应答器为列车提供对应区间的线路基础数据、临时限速信息、闭塞分区位置、信号机位置、应答器链接关系等信息。
该方法要求列车必须设置应答器接收装置(BTM)及对应天线，并需要地面设置有源应答器、与之相连的应答器专用电缆、地面电子单元(LEU)、列控中心等配套设备，设备增加过多，使得维护工作量也对应增加较多，对维护人员要求较高，维护成本也相应增加。

发车进路轨道电路接收器根据轨道信息办理发车进路状态信息，并将所述发车进路状态信息发送给车站联锁设备；
所述车站联锁设备根据所述发车进路状态信息生成发车进路信息，并将所述发车进路信息发送给发车进路轨道电路发送器；
所述发车进路轨道电路发送器对所述发车进路信息的载频和低频进行调整，并将调整后的发车进路信息发送至钢轨；
轨道电路信息读取器从钢轨接收所述调整后的发车进路信息，并对所述调整后的发车进路信息进行解调，将解调完的信息发送给列控车载设备。
本发明通过在站内固定区段设置安装轨道电路发送器、轨道电路接收器，发送特殊轨道电路编码信息，可实现接车进路及发车进路的地-车信息传输。其中，站内固定区段包括接车进路的固定区段和发车进路的固定区段。进一步地，所述接车进路的固定区段具体为接车进路第一个区段或接车进路上特定的一个或多个区段；所述发车进路的固定区段具体为发车进路最后一个区段或发车进路上特定的一个或多个区段。当列车在站内固定区段接收到进路信息后，可按照进路实际线路信息控制列车运行。需要说明的是，本发明中的进路信息的传输与轨道电路占用检查合为一体，实现地面是否可靠发送对应信息的闭环检查。
具体的，图3示出了本发明实施例的接车进路信息、发车进路信息的传输方法的原理示意图，如图3所示，本发明中的轨道电路以ZPW-2000轨道电路为例进行说明。本实施例中，站内固定区段以接车进路第一个区段和发车进路最后一个区段为例进行说明。接车进路第一个区段内的轨道电路发送器将轨道信息发送至钢轨，本实施例中，所述轨道信息以移频信号为例进行说明，轨道电路接收器从钢轨对移频信号进行接收。当区段无车占用时，轨道电路发送器将移频信号发送至钢轨，轨道电路接收器对从其接收端接 收到的移频信号进行解调，从而办理该区段为空闲状态，并输出区段空闲信息；当区段有车占用时，轨道电路发送器将移频信号发送至钢轨，列车轮对将钢轨短路，轨道电路接收器无法对从其接收端接收到的移频信号进行解调，从而办理该区段为占用状态，并输出区段占用信息。并且，车站联锁设备无需对区段占用状态再做处理，可以直接使用轨道电路输出的区段占用状态信息。当轨道电路发送器将移频信号发送至钢轨，而轨道电路接收器从钢轨上没有接收到移频信号，此时地面设备会给出报警信息，提示进路信息未传输至钢轨或出现故障。
本实施例中，当列车进入接车进路第一个区段(即图3中IIAG区段)之前，接车进路第一个区段的轨道电路接收器对接车进路第一个区段的轨道电路发送器发送的移频信号进行解调，从而办理该区段为空闲状态，并向车站联锁设备输出区段空闲信息。车站联锁设备根据区段空闲信息判断该区段没有列车，因此不发送接车进路信息。当列车进入接车进路第一个区段，列车轮对将钢轨短路，接车进路第一个区段的轨道电路接收器无法对接车进路第一个区段的轨道电路发送器发送的移频信号进行解调，从而办理该区段为占用状态，并向车站联锁设备输出区段占用状态信息。车站联锁设备根据区段占用状态信息生成接车进路信息，其中接车进路信息是选择在ZPW-2000低频信息中进行传输的，具体位置在第七个码位上。车站联锁设备根据接车进路信息从进路数据表中查找到对应的进路号，然后根据该进路号向当前区段的轨道电路发送器发送接车进路信息。其中，开始时机模块为车站联锁设备办理完成接车进路，并对应防护该接车进路的列车信号机开放；结束时机模块为防护该接车进路的列车信号机关闭，并当列车先占用再出清本区段后，停止发送接车进路信息。当前区段的轨道电路发送器接收到接车进路信息后，需要对其低频使用方式进行调整，可采用基准载频、小载频、低频等组合方式，不限于此，本实施例以载频和低频的组合为例进行示例性说明。车站联锁设备根据所述进路号在进路数据表中找到当前所述接车进路信息对应的载频和低频，如下表(1)所示：表(1)进路数据表
序号 进路类型 进路号 线别 低频信息 线别 低频信息 备注
1 接/发车进路 (1) 下行 1698.7-10.3 上行 1998.7-10.3  
2 接/发车进路 (2) 下行 1701.4-10.3 上行 2001.4-10.3  
3 接/发车进路 (3) 下行 1698.7-11.4 上行 1998.7-11.4  
4 接/发车进路 (4) 下行 1701.4-11.4 上行 2001.4-11.4  
5 接/发车进路 (5) 下行 1698.7-12.5 上行 1998.7-12.5  
6 接/发车进路 (6) 下行 1701.4-12.5 上行 2001.4-12.5  
7 接/发车进路 (7) 下行 1698.7-13.6 上行 1998.7-13.6  
8 接/发车进路 (8) 下行 1701.4-13.6 上行 2001.4-13.6  
9 接/发车进路 (9) 下行 1698.7-14.7 上行 1998.7-14.7  
10 接/发车进路 (10) 下行 1701.4-14.7 上行 2001.4-14.7  
然后将所述对应的载频和低频信息发送给当前区段的轨道电路发送器，当前区段的轨道电路发送器按照所述对应的载频和低频信息采用FSK(移频键控)形式对所述接车进路信息的载频和低频进行调整，并将上述信息发送至钢轨，同时完成列车占用检车功能。
需要说明的是，表(1)仅仅选取部分载频、低频组合作为示例，其余载频、低频组合也可使用。其中接车进路指的是进站走行的路径，发车进路指的是出站走行的路径；进路号指的是列车进站、出站时所走行的不同路径；线别为铁路线路走行方向，其中向北京方向运行为上行方向，向远离北京方向运行为下行方向，复线铁路一般为一条上行线、一条下行线；低频信息为载频和低频的组合，如序号1中的低频信息1998.7-10.3，其中1998.7Hz是载频，10.3Hz是低频。低频信息对应的含义仅为示例性说明，其含义可根据实际需求进行调整。
列车车载设备中的TCR(轨道电路信息读取器)通过感应线圈，接收轨道电路发送器通过钢轨发送的接车进路信息，并对该接车进路信息进行解调，将解调完的接车进路信息传输给车载ATP(列控车载设备或其他类型的列车控制设备)设备。车载ATP设备接收TCR设备提供的接车进路信息，结合线路数据、临时限速、列车信息等生成接车进路上的控车曲线，控制列车完成接车作业。
本实施例中，当列车驶入接车进路第一个区段之前，联锁根据已经办理好的接车进路，控制IIAG区段的轨道电路发送对应的接车进路信息，当列车压入IIAG后，车载TCR设备接收接车进路信息，当列车出清IIAG后(联锁接收到IIAG区段轨道电路接收器提供的IIAG区段由占用状态变为空闲状态)，联锁控制IIAG区段的轨道电路发送器停止发送接车进路信息。
本实施例中，当列车驶入发车进路最后一个区段之前，联锁根据已经办理好的发车进路，控制IIBG区段的轨道电路发送对应的发车进路信息，当列车压入IIBG后，车载TCR设备接收接车进路信息，当列车出清IIBG后(联锁接收到IIBG区段轨道电路接收器提供的IIBG区段由占用状态变为空闲状态)，联锁控制IIBG区段的轨道电路发送器停止发送发车进路信息。发车进路信息的传输原理与接车进路信息的传输原理相同，车 载ATP设备接收TCR设备提供的发车进路信息，选取该发车进路所对应的区间数据用于控制列车。
本实施例中，接车进路信息和发车进路信息均为全站唯一信息，故列车无需区分运行方向，即可准确判断所接收的是接车进路信息还是发车进路信息。
为了实现本实施例的接车进路信息、发车进路信息的传输方法，设置了接车进路信息、发车进路信息的传输系统。如图4所示，所述系统包括轨道电路接收器、车站联锁设备、轨道电路发送器、轨道电路信息读取器。具体的，轨道电路发送器将轨道信息发送至钢轨；轨道电路接收器从所述钢轨接收所述轨道信息；轨道电路接收器根据轨道信息办理区段状态信息，并将所述区段状态信息发送给车站联锁设备；车站联锁设备根据所述区段状态信息生成进路信息，并将所述进路信息发送给对应区段的轨道电路发送器；轨道电路发送器对所述进路信息的载频和低频进行调整，并将调整后的进路信息发送至钢轨；轨道电路信息读取器从钢轨接收所述调整后的进路信息，并对所述调整后的进路信息进行解调，将解调完的信息发送给列控车载设备。其中，车站联锁设备包括开始时机模块、结束时机模块。具体的，开始时机模块为车站联锁设备办理完成进路，并对应防护该进路的列车信号机开放；结束时机模块为防护该进路的列车信号机关闭，并当列车先占用再出清本区段后，停止发送进路信息。
本发明通过既有轨道电路设备，无需增加额外设备即可完成接车进路信息、发车进路信息的地-车信息传输，通过轨道电路传输接车进路信息及发车进路信息，可实现连续可靠传输。并且，进路信息仅需地面向列车单向传输，无需列车回执，不存在列车未收到进路信息而造车列车错用接车进路数据或区间基础数据的问题。本发明将进路信息与既有信号授权相结合，解决了现有技术中采用进路信息与信号授权两个通道，从而可能造成列车仅收到信号授权或进路信息的问题，提高了行车安全和行车效率。
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。
