Description

一种控制列车主变压器工作的方法及装置
本申请要求于2018年12月5日提交中国专利局、申请号为201811480052.8、发明名称为“一种控制列车主变压器工作的方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及列车网络控制技术领域，尤其涉及一种控制列车主变压器工作的方法及装置。
背景技术
目前，列车上的主变压器通过油循环来冷却降温，如果主变压器油温过高会造成主变压器内部的所有部件加速老化，降低其寿命。因此，列车网络控制系统对列车主变压器油温进行实时监控，当列车主变压器油温过高时，需要及时对列车主变压器的工作进行控制，以保护列车主变压器。
可以理解，保证对列车主变压器油温监测的有效性，是保证对列车主变压器进行有效保护的关键。因此列车网络控制系统监测列车主变压器油温监测传感器是否发生开路、短路、通信中断等故障现象，以便能够及时排除故障，保证监测的有效性。但是，还有一种情况是，如果负责监测主变压器油温的传感器或者采集卡错误识别到油温过高，会造成列车网络控制系统自动降低牵引变流器发挥功率或者断开牵引变流器的电力供应来保护主变压器，但是这必然会降低列车运行速度影响到运营秩序。
但是目前列车的网络控制系统并没有对监测到的列车主变压器油温数据的有效性进行判断、识别，而是直接将采集的油温数据用于对列车主变压器工作的控制。该控制过程存在很大可能造成对列车行驶的不当干预，影响列车运营秩序。

具体实施方式
本申请实施例技术方案适用于根据列车主变压器油温对列车主变压器的工作进行控制的应用场景。采用本申请实施例技术方案，可以准确识别列车主变压器油温数据的准确性，在此基础上对列车主变压器的工作进行合理控制。
图1示出了本申请实施例技术方案适用的一种对列车主变压器的工作进行控制的应用场景示意图。在主变压器的入油口1、入油口2、出油口1、出油口2处分别设置油温传感器，油温传感器采集主变压器油口的油温数据，并且将采集的油温数据发送给列车网络控制系统TCMS。列车网络控制系统将接收的各项油温数据用于油温计算，当主变压器油温过高时执行主变压器保护处理。
图1以两个入油口、两个出油口的主变压器结构为例说明对列车主变压器的油温进行采集的具体实现方式，在具体实施本申请实施例技术方案时，可以根据实际情况，针对列车主变压器的各个入油口和出油口分别设置油温传感器采集油口油温数据，并发送给列车网络控制系统TCMS。
一种示例性的油温数据采集上传实现方式是，入油口1油温数据和出油口1油温数据通过电路传输给TCMS(列车网络控制系统)的一个高压控制单元的PT100采集电路板上，定义为G1板卡；入油口2油温数据和出油口2油温数据通过电路传输给TCMS(列车网络控制系统)的另一个高压控制单元的PT100采集电路板上，定义为G2板卡。这两个相互独立，互不影响的高压控制单元将入油口1油温数据、出油口1油温数据、入油口2油温数据和出油口2油温数据通过现有通信技术传递给TCMS。
本申请实施例所提出的控制列车主变压器工作的方法，应用于图1所示的列车网络控制系统，具体为利用接收的列车主变压器各个油口的油温数据，对主变压器的工作进行控制，例如控制其工作功率等。
需要说明的是，本申请实施例技术方案可以以软件程序的方式存在于列车网络控制系统中，当该软件程序运行时实现对列车主变压器工作的控制。或者，本申请实施例技术方案还可以以硬件装置的形式存在于列车网络控制系统中，当该装置开始工作时，接收主变压器各个油口的油温数据，并以此为依据对列车主变压器的工作进行控制。当本申请实施例技术方案作为列车网络控制系统中的硬件装置实现控制列车主变压器的工作的功能时，其具体可以是处理器、单片机等。
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，而不是全部的实施例。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，都属于本申请保护的范围。
本申请实施例公开了一种控制列车主变压器工作的方法，参见图2所示，该方法包括：
S201、获取主变压器油温数据；
具体的，上述主变压器油温数据，是指主变压器的各个油口的油温数据，例如主变压器各个入油口的油温数据、各个出油口的油温数据等。上述油温数据由设置于主变压器各个入油口和各个出油口的油温传感器采集得到。
需要说明的是，设置于列车主变压器的各个油口的油温传感器，以设定的数据采集周期，周期性地对列车主变压器各个油口的油温进行采集，并且在一个采集周期结束后，将采集的油温数据同时发送至列车网络控制系统。
可以理解，列车网络控制系统也是周期性的接收主变压器各个油口的油温数据，在一个数据接收周期内，列车网络控制系统可以同时接收到列车主变压器的各个油口的油温数据，并且，列车网络控制系统还可以对各个周期接收的主变压器油温数据进行记录存储。
S202、根据所述主变压器的历史油温数据，判断所述主变压器油温数据是否为可信数据；
具体的，由于列车主变压器各个油口的油温传感器是周期性地采集油口的油温数据，并且上传给列车网络控制系统，列车网络控制系统将周期性地接收到的主变压器油温数据用于控制列车主变压器的工作。
鉴于对列车控制及时性的要求，列车网络控制系统接收列车主变压器油温数据的周期越小也好，则可以理解，在一个油温数据采集周期内，由于周期很小，列车主变压器的油温变化不会很大。也就是说，在两个相邻的油温数据采集周期，列车主变压器的油温变化应当在设定的变化范围内，如果超出这个范围，就可以认为采集的油温数据是不准确的，理论上不能将不准确的油温数据用于对列车主变压器的工作控制。
可以理解，通过将当前周期采集的列车主变压器油温数据与历史周期采集的列车主变压器油温数据进行对比，可以判断当前周期采集的列车主变压器油温数据是否为有效数据，即是否为可信数据。
如果经过判断确定当前周期获取的主变压器油温数据不是可信数据，则列车网络控制系统不对列车主变压器的工作进行控制，并输出告警信息，提示工作人员检修列车主变压器各个油口的油温传感器。
如果所述主变压器油温数据是可信数据，则执行步骤S203、根据所述主变压器油温数据对所述主变压器的工作进行控制处理。
具体的，本申请实施例对每一周期所采集的主变压器油温数据进行是否可信的判断后，只根据可信的油温数据对列车主变压器的工作进行控制处理。上述控制处理，包括降低牵引变流器功率、停止主变压器启动等。
通过上述介绍可见，本申请实施例技术方案结合列车主变压器的历史油温数据，对当前采集的主变压器油温数据的可信度进行判断，识别采集的主变压器油温数据是否可信，如果可信则用于对列车主变压器的工作进行控制处理。上述处理过程保证了对列车主变压器的工作进行控制处理的依据的可信度和有效性，从而可以避免由于采集的列车主变压器油温数据不准确造成对列车主变压器的工作的不当干预。
可选的，在本申请的另一个实施例中，公开了上述根据所述主变压器的历史油温数据，判断所述主变压器油温数据是否为可信数据的具体处理过程。
参见图3所示，所述根据所述主变压器的历史油温数据，判断所述主变压器油温数据是否为可信数据，包括：
S302、判断所述主变压器油温数据与所述主变压器的上一油温监测周期的油温数据的差值是否大于预设的第一差值，以及S303、判断所述主变压器油温数据的值是否大于预设的油温值；
如果所述主变压器油温数据与所述主变压器的上一油温监测周期的油温数据的差值不大于预设的第一差值，和/或所述主变压器油温数据的值不大于预设的油温值，则执行步骤S304、确定所述主变压器油温数据为可信数据。
具体的，上述第一差值，是根据经验设定的，列车主变压器在两个相邻的油温采集周期的油温数据差值的最大值。
上述预设的油温值，是指列车主变压器油温的最大值。
上述的第一差值和预设的油温值，都可以是经验设定值。
本申请实施例计算当前列车主变压器油温监测周期下检测到的油温数据，与上一油温监测周期下检测到的油温数据的差值，并将该差值与预设的第一差值进行对比，判断该差值是否大于预设的第一差值；
同时，判断当前列车主变压器油温监测周期下检测到的油温数据的值是否大于预设的油温值，也就是判断是否大于列车主变压器油温的最大值。
如果当前列车主变压器油温监测周期下检测到的油温数据，与上一油温监测周期下检测到的油温数据的差值大于预设的第一差值，并且当前列车主变压器油温监测周期下检测到的油温数据的值大于预设的油温值，则可以确定当前列车主变压器油温监测周期下检测到的油温数据是不可信的数据，也就是存在严重误差的数据。
相反，如果当前列车主变压器油温监测周期下检测到的油温数据与上一油温监测周期下检测到的油温数据的差值不大于预设的第一差值，和/或当前列车主变压器油温监测周期下检测到的油温数据的值不大于预设的油温值，则可以确定当前列车主变压器油温监测周期下检测到的油温数据是可信数据，即可以用于作为对列车主变压器工作进行控制的依据。
例如，假设上述第一差值为15度，上述预设的油温值为105度，则本申请实施例在获取到列车主变压器的油温数据后，判断本次获取的油温数据的值与上一周期获取的油温数据的值的差值是否大于15度，以及判断本次获取的油温数据的值是否大于105度。
如果本次获取的油温数据的值与上一周期获取的油温数据的值的差值大于15度，并且本次获取的油温数据的值大于105度，则可以确定本次获取的油温数据不可信；
相反，如果本次获取的油温数据的值与上一周期获取的油温数据的值的差值不大于15度，和/或本次获取的油温数据的值不大于105度，则可以确定本次获取的油温数据为可信数据。
需要说明的是，上述介绍的判断油温数据是否为可信数据的方法在具体实现时可以通过通用的可编程逻辑语言实现。
本实施例中的步骤S301、S305分别对应图2所示的方法实施例中的步骤S201、S203，其具体内容请参见图2所示的方法实施例的内容，此处不再赘述。
进一步的，参见图1所示，由于列车主变压器的油口分为入油口和出油口，并且入油口和出油口的数量不唯一，因此，上述的主变压器油温数据，具体包括主变压器各个入油口和出油口的油温数据。
因此，上述判断主变压器油温数据是否为可信数据，在实际执行中可能是分别判断主变压器各个油口的油温数据是否为可信数据。由图1可见，采集主变压器油温分四路，为主变压器入口1油温、入口2油温、出口1油温、出口2 油温。如果本次某一路(比如入口1)获取的油温数据不可信，则将该路油温数据不可信记录为三级故障代码，储存在列车网络控制系统中，以便于检修维护人员下载故障数据时发现调查分析该故障并更换该路传感器或者相应采集板卡，但是三级故障代码不提示给司机，也不会干扰司机正常驾驶操作。然后，再次判断其他三路油温是否可信，判断方法同上，最终筛选出可信的油温数据最大值，可进行对列车主变压器工作进行控制的依据。
在此基础上，参见图4所示，所述根据所述主变压器的历史油温数据，判断所述主变压器油温数据是否为可信数据，具体为：
S402、根据所述主变压器的各个入油口和出油口的历史油温数据，判断所述主变压器的油温最高的入油口的油温数据是否为可信数据。
具体的，基于上述的，列车主变压器油温数据具体包括列车主变压器各个入油口和出油口的油温数据，列车主变压器的历史油温数据，也包括列车主变压器的各个入油口和出油口的历史油温数据。
由于列车网络控制系统通常是以列车主变压器的最高油温为依据对列车主变压器的工作进行控制，因此当依据列车主变压器各个入油口和出油口的油温数据对列车主变压器的工作进行控制时，也需要根据温度最高的入油口或出油口的油温数据对列车主变压器的工作进行控制。
一般情况下，列车主变压器的入油口温度比出油口温度高，因此本申请实施例在获取列车主变压器的各个入油口和出油口的油温数据后，从中识别到温度最高的入油口的油温数据，然后依据主变压器相应入油口的历史油温数据，判断该入油口的油温数据是否为可信数据，具体判断过程可参见图3所示的方法实施例中的判断方法。
如果经过判断确定列车主变压器油温最高的入油口的油温数据为可信数据，则执行步骤S403、根据主变压器油温最高的入油口的油温数据对主变压器的工作进行控制处理；
如果经过判断确定列车主变压器油温最高的入油口的油温数据为不可信数据，则执行步骤S404、从列车主变压器其它入油口和出油口的油温数据中，选择可信的油温数据用于对主变压器的工作进行控制处理。
具体的，当判断确认列车主变压器油温最高的入油口的油温数据为不可信数据时，本申请实施例从列车主变压器其它入油口和出油口的油温数据中，选 择可信的油温数据用于对列车主变压器的工作进行控制处理。
进一步的，由于列车主变压器的入油口的油温高于出油口的油温，因此本申请实施例设定，当从主变压器其它入油口和出油口的油温数据中，选择可信的油温数据用于对主变压器的工作进行控制处理时，优先根据主变压器的各个入油口和出油口的历史油温数据，分别判断主变压器其它各个入油口的油温数据是否为可信数据，具体的判断方法可参见图3所示的判断方法。
如果列车主变压器的其他各个入油口的油温数据中存在可信数据时，则从主变压器的其他各个入油口的可信油温数据中，选择油温最高的入油口可信油温数据用于对主变压器的工作进行控制处理。
如果列车主变压器的其他各个入油口的油温数据中不存在可信数据，则进一步判断主变压器的各个出油口的油温数据中，是否存在可信数据；
如果存在可信数据，则选择主变压器出油口油温数据中油温最高的可信数据用于对主变压器的工作进行控制处理；
如果不存在可信数据，则输出报警信息，使工作人员进行人工处理。
例如，假设经过判断确认图1所示的主变压器的油温最高的入油口1的油温数据为不可信数据，此时本申请实施例继续判断主变压器的入油口2的油温数据是否为可信数据，如果是可信数据，则以入油口2的油温数据为依据对主变压器的工作进行控制处理；如果不是可信数据，则进一步判断主变压器的出油口1和出油口2的油温数据是否为可信数据，如果均为可相信数据，则选择其中的油温最高的油温数据作为控制住变压器工作的油温数据；如果只存在一个出油口的油温数据为可信数据，则依据该可信的出油口油温数据为依据对主变压器的工作进行控制处理；如果不存在可信数据，则输出报警信息，提示工作人员进行人工处理。
本实施例中的步骤S401、S403分别对应图2所示的方法实施例中的步骤S201、S203，其具体内容请参见图2所示的方法实施例的内容，此处不再赘述。

控制处理单元120，用于当所述主变压器油温数据是可信数据时，根据所述主变压器油温数据对所述主变压器的工作进行控制处理。
可选的，在本申请的另一个实施例中，参见图6所示，所述数据判断单元110，包括：

如果所述主变压器油温数据与所述主变压器的上一油温监测周期的油温数据的差值不大于预设的第一差值，和/或所述主变压器油温数据的值不大于预设的油温值，则确定所述主变压器油温数据为可信数据。
其中，所述主变压器油温数据，包括主变压器各个入油口和出油口的油温数据；

第二处理单元，用于当所述主变压器的油温最高的入油口的油温数据不是可信数据时，从所述主变压器其它入油口和出油口的油温数据中，选择可信的油温数据用于对所述主变压器的工作进行控制处理。
其中，所述第二处理单元从所述主变压器其它入油口和出油口的油温数据中，选择可信的油温数据用于对所述主变压器的工作进行控制处理时，具体用于：
