Abstract

A method and device for deicing a brake disk, which are applied in the technical field of rail vehicles. The method comprises: determining whether a rail vehicle enters a preset high-temperature environment under a preset low-temperature vehicle condition within a first duration; if braking is not performed within the first duration when the vehicle enters the preset high-temperature environment under the preset low-temperature vehicle condition, it may be determined that the brake disk has been iced over, that is, a brake mechanism may be controlled to brake at a preset braking pressure. Without affecting the driving of the vehicle, friction is used to generate heat for removing ice from a surface of the brake disk, thereby ensuring that the brake disk has a good braking effect when a driver is actually decelerating or stopping, which thus ensures the safe operation of the rail vehicle.

为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of the embodiments of the present invention, but not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.
在冬季的严寒气候下，制动盘表面有时会形成一层薄冰，这层附着的薄冰会导致制动盘的摩擦系数急剧下降，制动效果明显降低，影响行车安全。发明人研究发现，当轨道车辆从温度较低的环境中经温度较高的环境中，比如，车 库、地下车站以及特别长的隧道，并且在进入温度较高的环境中之前以及进入温度较高的环境的过程中，轨道车辆未进行制动的话，轨道车辆的制动盘表面就会出现结冰现象。In the severe cold weather in winter, a thin layer of ice may form on the surface of the brake disc. This layer of thin ice will cause the friction coefficient of the brake disc to drop sharply, and the braking effect will be significantly reduced, affecting driving safety. The inventors found that when rail vehicles pass from a lower temperature environment to a higher temperature environment, such as a garage, an underground station, and a particularly long tunnel, and before entering a higher temperature environment and entering a higher temperature In the process of the environment, if the rail vehicle does not brake, the surface of the brake disc of the rail vehicle will freeze.
基于上述研究发现，提供本发明申请实施例所述的制动盘除冰方法及装置，参见图1，图1是本发明实施例提供的制动盘除冰方法的流程图，该方法可应用于轨道车辆的控制设备以及相应的轨道车辆的控制***之中，显然，该控制设备或控制***在某些情况下也可选用网络侧的服务器实现。Based on the above findings, the method and device for de-icing a brake disc according to an embodiment of the present application are provided. Refer to FIG. 1. FIG. 1 is a flowchart of a method for de-icing a brake disc according to an embodiment of the present invention. This method can be applied. Among the control equipment of the rail vehicle and the corresponding control system of the rail vehicle, it is obvious that the control equipment or the control system can also be implemented by a server on the network side in some cases.
参照图1，本发明实施例提供的制动盘除冰方法可以包括：Referring to FIG. 1, the brake disc deicing method provided by the embodiment of the present invention may include:
步骤S100，判断轨道车辆是否在第一时长内以预设低温车况进入预设高温环境，并且在第一时长内未进行制动。若是，执行步骤S110；若否，退出本次控制过程。In step S100, it is determined whether the rail vehicle enters the preset high-temperature environment with the preset low-temperature vehicle condition within the first time period, and the brake is not applied within the first time period. If yes, go to step S110; if not, exit this control process.
基于前述研究发现的内容，轨道车辆的制动盘结冰需要一定的前提条件，首先，轨道车辆的制动盘的温度较低。公知的，轨道车辆在行驶过程中会根据实际运行需求进行必要的制动，现有技术中，轨道车辆基于制动盘进行制动的方式即为摩擦制动，在制动的过程中必然会因为摩擦而产生热量，温度较高的制动盘表面自然是不会结冰的。因此，轨道车辆的低温工况可以限定为：轨道车辆在低温环境中未进行制动的第二时长大于或等于第一时间阈值，即不仅要求轨道车辆所处的环境温度较低，同时，在处于低温环境时轨道车辆还没有进行制动操作，保证制动盘表面的温度较低。具体的，可以对低温环境进行限定，给定第一温度阈值，环境温度小于或等于第一温度阈值的环境即可认为是低温环境。Based on the findings of the foregoing research, the icing of the brake discs of rail vehicles requires certain prerequisites. First, the temperature of the brake discs of rail vehicles is low. It is well known that rail vehicles will perform necessary braking according to actual operating requirements during driving. In the prior art, the way that rail vehicles brake based on brake discs is friction braking, which will inevitably occur during braking Because of the heat generated by friction, the surface of the brake disk with a higher temperature will naturally not freeze. Therefore, the low-temperature operating conditions of the rail vehicle can be defined as: the second time that the rail vehicle does not brake in the low-temperature environment is greater than or equal to the first time threshold, that is, not only requires the ambient temperature of the rail vehicle to be lower, but also When in a low-temperature environment, the rail vehicle has not yet performed a braking operation to ensure that the temperature of the brake disc surface is low. Specifically, a low-temperature environment may be defined. Given a first temperature threshold, an environment whose ambient temperature is less than or equal to the first temperature threshold may be considered a low-temperature environment.
需要说明的是，轨道车辆不进行制动的情况至少有两种，即轨道车辆处于停放状态时，或者，虽然轨道车辆处于行驶状态，但轨道车辆并未进行制动操作，这两种情况都可以认为轨道车辆未进行制动。It should be noted that there are at least two situations where the rail vehicle is not braking, that is, when the rail vehicle is parked, or, although the rail vehicle is in the running state, the rail vehicle is not braking, both of which are It can be considered that the rail vehicle is not braking.
进一步的，判断轨道车辆的制动盘是否结冰，还需要对轨道车辆以预设低温车况进入高温环境的时间进行限定。可以想到的是，如果轨道车辆以低温车 况进入高温环境的时间较长，轨道车辆有足够的时间适应高温环境，车辆自身，包括制动盘，温度都会逐渐升高至预设高温环境的温度，或者说即使没有升高至预设高温环境的温度，而是升高到不会发生结冰的温度值，在此种情况下，制动盘同样是不会发生结冰的。还可以想到的是，轨道车辆在进入高温环境的过程中，如果进行了制动操作，由于摩擦生热，使得制动盘表面的温度升高，即使进入高温环境的时间满足要求，由于制动盘表面温度已然升高，制动盘也不会发生结冰。因此，本发明申请实施例限定车辆以预设低温车况进入高温环境的时长为第一时长，当轨道车辆在第一时长内以预设低温车况进入预设高温环境，并且在第一时长内未进行制动时，即可判定制动盘结冰。Further, to determine whether the brake disc of the rail vehicle is frozen, it is also necessary to limit the time for the rail vehicle to enter the high temperature environment under the preset low temperature vehicle condition. It is conceivable that if the rail vehicle enters the high-temperature environment for a long time under low-temperature conditions, the rail vehicle has enough time to adapt to the high-temperature environment. The temperature of the vehicle itself, including the brake disc, will gradually rise to the temperature of the preset high-temperature environment. In other words, even if it is not increased to the temperature of the preset high temperature environment, it is increased to a temperature value at which icing does not occur. In this case, the icing of the brake disc will also not occur. It is also conceivable that when the rail vehicle enters a high-temperature environment, if the brake operation is performed, the temperature of the brake disc surface rises due to frictional heat generation, even if the time to enter the high-temperature environment meets the requirements. The surface temperature of the disc has risen, and the brake disc will not freeze. Therefore, the embodiment of the present application limits the duration that the vehicle enters the high-temperature environment with the preset low-temperature vehicle condition as the first duration, and when the rail vehicle enters the preset high-temperature environment with the preset low-temperature vehicle condition within the first duration, and does not enter the first period of time When braking, it can be determined that the brake disc is frozen.
步骤S110，控制制动机构以预设制动压力进行制动，去除制动盘表面结冰。In step S110, the braking mechanism is controlled to perform braking with a preset braking pressure to remove ice on the surface of the brake disc.
在判定制动盘发生结冰后，即可控制制动机构进行制动操作，以预设压力进行制动，使制动盘因为摩擦而产生热量，从而去除制动盘表面的结冰。After it is determined that the brake disc is frozen, the brake mechanism can be controlled to perform a braking operation, and the brake is braked at a preset pressure, so that the brake disc generates heat due to friction, thereby removing ice on the surface of the brake disc.
可选的，为保证除冰的过程中不影响轨道车辆的正常行驶，需要对制动压力进行限定，既可以满足通过摩擦产生足够热量，将制动盘表面的结冰去除，同时，还不能产生太强的制动力，对车辆的正常行驶造成明显的影响。经过试验证实，可以将预设制动压力的取值范围限定在40-80kpa，在此范围内的制动压力产生的制动效果即可满足上述要求。Optionally, in order to ensure that the normal running of the rail vehicle is not affected during the de-icing process, the brake pressure needs to be limited, which can meet the requirement of generating sufficient heat through friction to remove the ice on the surface of the brake disc. Too much braking force is produced, which has a significant impact on the normal driving of the vehicle. It has been verified by experiments that the value range of the preset braking pressure can be limited to 40-80 kpa, and the braking effect produced by the braking pressure within this range can meet the above requirements.
综上所述，通过本发明是实施例提供的制动盘除冰方法，结合轨道车辆的车况以及环境温度的变化情况，判定制动盘是否发生结冰，并在判定轨道车辆发生结冰后，控制制动机构以预设制动压力进行制动，在不影响车辆行驶的前提下，利用摩擦生热，去除制动盘表面结冰，从而确保当司机进行实际减速或停车时，制动盘具有良好的制动效果，保障轨道车辆的安全运行。In summary, through the brake disc deicing method provided by the embodiment of the present invention, it is determined whether the brake disc has frozen due to the change of the vehicle condition of the rail vehicle and the ambient temperature, and after determining that the rail vehicle has frozen , Control the brake mechanism to brake with the preset brake pressure, use the heat generated by friction to remove the ice on the surface of the brake disc without affecting the driving of the vehicle, so as to ensure that when the driver actually decelerates or stops, the brake The disc has a good braking effect to ensure the safe operation of rail vehicles.
可选的，根据前述低温车况的限定条件，以及制动盘结冰的判定过程可知，对于轨道车辆的控制***而言，制动盘是否结冰的判定可以通过获取环境温度实测值以及统计自身进行制动操作的具体情况进行。因此，参见图2，本发明 申请实施例提供的另一种制动盘除冰方法流程图，该流程可以包括：Optionally, according to the aforementioned limiting conditions of low-temperature vehicle conditions and the determination process of the brake disc icing, for the control system of the rail vehicle, the determination of whether the brake disc is icing can be obtained by obtaining the actual measured value of the ambient temperature and counting itself Carry out the specific conditions of the brake operation. Therefore, referring to FIG. 2, a flowchart of another method for deicing a brake disc according to an embodiment of the present application may include:
步骤S200，统计轨道车辆所处环境的环境温度小于或等于第一温度阈值，且轨道车辆未进行制动的第二时长。Step S200: Count the second time period when the ambient temperature of the environment where the rail vehicle is located is less than or equal to the first temperature threshold, and the rail vehicle is not braking.
根据图1所示实施例记载的内容可知，对于低温环境的限定可以通过指定温度限值的方式进行。本发明实施例指定第一温度阈值，当环境温度小于或等于第一温度阈值时，即可认定当前环境为低温环境。According to the content described in the embodiment shown in FIG. 1, the limitation of the low-temperature environment can be performed by specifying the temperature limit. The embodiment of the present invention specifies the first temperature threshold, and when the ambient temperature is less than or equal to the first temperature threshold, the current environment can be regarded as a low-temperature environment.
进一步的，要判定轨道车辆是否处于预设低温车况还要统计轨道车辆在低温环境下未进行制动的第二时长。Further, to determine whether the rail vehicle is in a preset low-temperature vehicle condition, it is also necessary to count the second time period when the rail vehicle does not brake in a low-temperature environment.
需要说明的是，本发明实施例中述及的第二时长，指的是轨道车辆在低温环境下未进行制动的连续的时长，并非未进行制动的累计时长。It should be noted that the second duration mentioned in the embodiments of the present invention refers to the continuous duration of the rail vehicle without braking in a low-temperature environment, not the cumulative duration of without braking.
步骤S210，统计轨道车辆进入预设高温环境，且轨道车辆未进行制动的第一时长。Step S210: Count the first time period when the rail vehicle enters a preset high-temperature environment and the rail vehicle does not brake.
根据前述内容可知，为保证轨道车辆制动盘以低温状态进入预设高温环境，需要对轨道车辆以预设低温车况进入预设高温环境的时长进行限定，并将该时长作为判定条件之一，避免轨道车辆进入预设高温环境的时间过长，使得制动盘表面温度升高到不足以结冰的温度。According to the foregoing, to ensure that the brake disc of the rail vehicle enters the preset high temperature environment at a low temperature, it is necessary to limit the length of time that the rail vehicle enters the preset high temperature environment under the preset low temperature vehicle condition, and use this duration as one of the judgment conditions To avoid the time that the rail vehicle enters the preset high temperature environment for too long, so that the surface temperature of the brake disc rises to a temperature that is insufficient to freeze.
可选的，对于预设高温环境的限定，同样可以通过制定预设高温限值的方式进行。当轨道车辆获取的环境温度高于或等于该预设高温限值时，即可判定轨道车辆已经进入高温环境，同理，当轨道车辆获取的环境温度低于预设高温限值时，则判定轨道车辆未进入高温环境。Optionally, the limitation of the preset high temperature environment can also be performed by formulating the preset high temperature limit. When the ambient temperature acquired by the rail vehicle is higher than or equal to the preset high temperature limit, it can be determined that the rail vehicle has entered the high temperature environment. Similarly, when the ambient temperature acquired by the rail vehicle is lower than the preset high temperature limit, it is determined The rail vehicle has not entered the high temperature environment.
步骤S220，判断第一时长是否小于或等于第四时间阈值、以及第二时长是否大于或等于第一时间阈值；若是，执行步骤S230；若否，执行步骤S260。In step S220, it is determined whether the first duration is less than or equal to the fourth time threshold, and whether the second duration is greater than or equal to the first time threshold; if so, step S230 is performed; if not, step S260 is performed.
在获取得到第一时长和第二时长后，需要对二者进行判断。通过前述内容可知，对于第一时长的要求应该是足够短，避免制动盘温度升高，对于第二时长的要求应该是足够长，保证制动盘确实处于能够结冰的低温状态。对于第二时长与第一时间阈值的关系，前述内容已经记载清楚，此处不再赘述。After obtaining the first duration and the second duration, it is necessary to judge both. It can be known from the foregoing that the requirement for the first duration should be short enough to avoid the temperature rise of the brake disc, and the requirement for the second duration should be long enough to ensure that the brake disc is indeed in a low temperature state that can freeze. As for the relationship between the second duration and the first time threshold, the foregoing content has been clearly recorded and will not be repeated here.
需要说明的是，本实施例中虽然给定了第四时间阈值，并判断第一时长是否小于或等于第四时间阈值。但显然这种限定与图1所示实施例中判断轨道车辆是否在第一时长内以预设低温车况进入预设高温环境的判断实质是一致的，图2所示实施例虽然给定第四时间阈值，但只有在轨道车辆小于或等于该第四 时间阈值的情况下，才判定条件成立，这与图1所示实施例中轨道车辆在第一时长内以预设低温车况进入预设高温环境才判定条件成立是异曲同工的。It should be noted that although a fourth time threshold is given in this embodiment, and it is determined whether the first duration is less than or equal to the fourth time threshold. However, it is clear that this limitation is substantially the same as the judgment in the embodiment shown in FIG. 1 to determine whether the rail vehicle enters the preset high-temperature environment with the preset low-temperature vehicle condition within the first period of time. Although the embodiment shown in FIG. Time threshold, but only if the rail vehicle is less than or equal to the fourth time threshold, the condition is determined to be true, which is the same as the rail vehicle in the embodiment shown in FIG. 1 enters the preset high temperature with the preset low temperature condition within the first time The environment determines that the establishment of the conditions is the same.
步骤S230，统计轨道车辆进入预设高温环境，且未进行制动的第三时长。Step S230: Count the third time period when the rail vehicle enters the preset high-temperature environment without braking.
可选的，本实施例中对轨道车辆进入预设高温环境后的情况进行进一步限定，统计轨道车辆进入预设高温环境且未进行制动的第三时长。Optionally, in this embodiment, the situation after the rail vehicle enters the preset high-temperature environment is further limited, and the third time period during which the rail vehicle enters the preset high-temperature environment and does not perform braking is counted.
步骤S240，判断第三时长是否大于或等于第二时间阈值。Step S240: Determine whether the third duration is greater than or equal to the second time threshold.
在获取轨道车辆进入预设高温环境且未进行制动的第三时长后，需要对第三时长进行判断，如果第三时长大于或等于第二时间阈值，则可以判定制动盘表面发生结冰，进而需要执行步骤S250。After obtaining the third time period when the rail vehicle enters the preset high-temperature environment without braking, the third time period needs to be judged, and if the third time period is greater than or equal to the second time threshold, it can be determined that ice has occurred on the surface of the brake disc , And then step S250 needs to be executed.
在此步骤判断中，需要特别说明的是，如果轨道车辆进入预设高温环境的时长小于第二时间阈值，说明此时制动盘表面的冰层仍未充分凝结，需要继续等待，返回步骤S230对轨道车辆进入预设高温环境的时间进行计时，直到该第三时长大于或等于第二时间阈值，并且在这个过程中，轨道车辆未进行制动。此外，如果轨道车辆在进入预设高温环境后，不管第三时长是否满足前述要求，只要轨道车辆进行了制动操作，则可以认为制动盘已经发生摩擦生热，制动盘表面不会再存在冰层附着，此时即可执行步骤S260，退出控制过程。In the judgment of this step, it should be noted that if the duration of the rail vehicle entering the preset high temperature environment is less than the second time threshold, it means that the ice layer on the surface of the brake disc is still not sufficiently condensed at this time, and it needs to continue to wait and return to step S230 The time when the rail vehicle enters the preset high-temperature environment is counted until the third duration is greater than or equal to the second time threshold, and during this process, the rail vehicle does not brake. In addition, if the rail vehicle enters the preset high-temperature environment, regardless of whether the third time period meets the foregoing requirements, as long as the rail vehicle has performed the braking operation, it can be considered that the brake disc has generated friction and heat, and the brake disc surface will not If there is ice adhesion, step S260 can be executed at this time to exit the control process.
步骤S250，控制制动机构以预设制动压力进行制动，去除制动盘表面结冰。In step S250, the braking mechanism is controlled to perform braking with a preset braking pressure to remove ice on the surface of the brake disc.
如果前述判断条件全部成立，则可以判定制动盘表面结冰，进而控制制动机构以预设制动压力进行制动，去除制动盘表面的结冰。If all the foregoing judgment conditions are satisfied, it can be determined that the brake disc surface is frozen, and then the brake mechanism is controlled to brake with a preset brake pressure to remove the ice on the brake disc surface.
对于预设制动压力的选取，前述内容已经阐明，此处不再赘述。For the selection of the preset braking pressure, the foregoing has been clarified and will not be repeated here.
可选的，在控制制动机构以预设制动压力进行制动的过程中，可以统计制动机构以预设制动压力进行制动的第四时长，当该第四时长达到给定的第三时间阈值时，则认为制动盘表面的结冰已经去除完毕，控制制动机构停止制动，轨道车辆恢复正常运行。Optionally, during the process of controlling the braking mechanism to perform braking at the preset braking pressure, the fourth duration of braking by the braking mechanism at the preset braking pressure may be counted, and when the fourth duration reaches a given At the third time threshold, it is considered that the icing on the surface of the brake disc has been removed, the brake mechanism is controlled to stop braking, and the rail vehicle resumes normal operation.
可选的，在控制制动机构以预设制动压力进行制动的过程中，还可以统计制动机构以预设制动压力进行制动后轨道车辆预设目标车轮的转动圈数，由于预设目标车轮的标准周长是已知的，因此，可以通过计算预设目标车轮的标准周长与转动圈数的乘积，得到轨道车辆的运行距离，当轨道车辆的运行距离达到预设距离阈值时，同样可以认为制动盘表面的结冰已经去除，控制制动机构停止制动，轨道车辆恢复正常运行。Optionally, in the process of controlling the braking mechanism to perform braking at a preset braking pressure, it is also possible to count the number of rotations of the preset target wheel of the rail vehicle after the braking mechanism performs braking at the preset braking pressure, because The standard circumference of the preset target wheel is known, therefore, the running distance of the rail vehicle can be obtained by calculating the product of the standard circumference of the preset target wheel and the number of rotations, when the running distance of the rail vehicle reaches the preset distance At the threshold, it can also be considered that the icing on the surface of the brake disc has been removed, the brake mechanism is controlled to stop braking, and the rail vehicle resumes normal operation.
步骤S260，退出控制过程。Step S260, exit the control process.
当上述条件不满足，退出控制过程，不对制动盘进行除冰作业。When the above conditions are not met, the control process is exited and the brake disc is not de-iced.
通过本发明实施例提供的制动盘除冰方法，轨道车辆可以通过外部环境温度的变化以及车辆自身的动作过程判断制动盘是否发生结冰，并在判定制动盘结冰后，控制制动进行制动，去除制动盘表面的结冰，保证轨道车辆在真正进行制动时，具有良好的制动效果。With the brake disc deicing method provided by the embodiment of the present invention, the rail vehicle can determine whether the brake disc is frozen by the change of the external ambient temperature and the vehicle's own motion process, and after determining that the brake disc is frozen, the control system Braking is performed to remove icing on the surface of the brake disc to ensure that the rail vehicle has a good braking effect when it is actually braking.
