绝缘故障的诊断方法及系统、存储介质、电子设备Insulation fault diagnosis method and system, storage medium, electronic equipment

技术领域technical field

本申请涉及氢燃料电池车辆技术领域，特别是涉及一种绝缘故障的诊断方法及系统、存储介质、电子设备。The present application relates to the technical field of hydrogen fuel cell vehicles, in particular to a method and system for diagnosing insulation faults, a storage medium, and electronic equipment.

背景技术Background technique

基于氢燃料电池清洁无污染的优势，以氢燃料电池作为动力系统的氢燃料电池车辆近几年在国内开始推广并进入示范运营阶段。然而由于电堆与冷却液直接接触，导致电堆结构设计、材料性能以及冷却液电导率对新能源车辆的绝缘性影响极大，从示范运营的故障率来看，绝缘故障是氢燃料电池车辆运营故障中出现频次较高的故障，尤其是偶发性故障，因此，对于氢燃料电池车辆绝缘故障的高效诊断尤为重要。Based on the clean and pollution-free advantages of hydrogen fuel cells, hydrogen fuel cell vehicles using hydrogen fuel cells as power systems have been promoted in China in recent years and have entered the demonstration operation stage. However, due to the direct contact between the stack and the coolant, the structural design of the stack, the material properties, and the conductivity of the coolant have a great impact on the insulation of new energy vehicles. From the perspective of the failure rate of the demonstration operation, insulation failure is the main cause of hydrogen fuel cell vehicles. Operational faults occur frequently, especially sporadic faults. Therefore, efficient diagnosis of insulation faults in hydrogen fuel cell vehicles is particularly important.

目前，大多是在氢燃料电池车辆内安装绝缘监测仪，对氢燃料电池车辆全生命周期绝缘阻值进行监控，，当绝缘阻值低于整车设定的最低报警阈值时，车辆通过仪表上报绝缘故障，并提示驾驶员就近停车并通知服务人员处理，并且在停车之后切断整车高压。At present, most insulation monitors are installed in hydrogen fuel cell vehicles to monitor the insulation resistance of hydrogen fuel cell vehicles throughout their life cycle. When the insulation resistance is lower than the minimum alarm threshold set by the vehicle, the vehicle will report to Insulation failure, prompt the driver to stop nearby and notify the service personnel to deal with it, and cut off the high voltage of the vehicle after parking.

然而，由于采用的绝缘阻值过低即停止使用车辆的处理方式较为简单武断，以及等待服务人员处理的过程耗时较长，降低用户体验感的同时，也增加了排查故障耗费的时间成本以及人工成本。因此，亟需一种绝缘故障的诊断方法，以解决上述问题。However, due to the simple and arbitrary processing method of stopping the vehicle when the insulation resistance value is too low, and the long waiting process for the service personnel, it reduces the user experience and increases the time and cost of troubleshooting. Labor cost. Therefore, there is an urgent need for a diagnostic method for insulation faults to solve the above problems.

本申请实施例提供了一种绝缘故障的诊断方法，如图1所示，该方法包括：The embodiment of the present application provides a method for diagnosing insulation faults, as shown in Figure 1, the method includes:

101、实时获取目标对象的绝缘阻值数据。101. Obtain the insulation resistance data of the target object in real time.

其中，目标对象可以是纯氢燃料电池车辆，或是混合动力车辆，例如，氢燃料电池汽车、氢燃料电车矿车、混合动力汽车、混合动力矿车等，也可以是其他电力系统，本申请实施例不做具体限定。本申请实施例中，当前执行端可以是电力系统的控制端，例如，车辆电力系统的控制中心等，通过高精度传感器实时获取目标对象的绝缘阻值数据，以实现对目标对象绝缘阻值的监测。Among them, the target object can be a pure hydrogen fuel cell vehicle, or a hybrid vehicle, for example, a hydrogen fuel cell vehicle, a hydrogen fuel tram car, a hybrid car, a hybrid mine car, etc., or other power systems. Examples are not specifically limited. In the embodiment of the present application, the current execution terminal may be the control terminal of the power system, for example, the control center of the vehicle power system, etc., and obtain the insulation resistance data of the target object in real time through high-precision sensors, so as to realize the control of the insulation resistance value of the target object. monitor.

需要说明的是，当前执行端可以配置在车辆驾驶席的仪表中控位置，以供驾驶员实时了解车辆的实际实际状况，还可以配置在服务端，通过与车辆之间的通讯连接对车辆进行远程监控，本申请实施例不做具体限定。It should be noted that the current execution end can be configured in the central control position of the instrument in the driver's seat of the vehicle, so that the driver can understand the actual situation of the vehicle in real time. Remote monitoring is not specifically limited in this embodiment of the application.

102、当监测到绝缘阻值数据低于预设绝缘阻值阈值，且超过预设持续时长阈值时，输出绝缘阻值过低的告警提示信息。102. When it is detected that the insulation resistance data is lower than the preset insulation resistance threshold and exceeds the preset duration threshold, output an alarm message indicating that the insulation resistance is too low.

其中，预设绝缘阻值阈值以及预设持续时长阈值可以根据目标对象的设计数据进行配置，还可以通过对历史事故记录进行统计后配置。本申请实施例中，当当前执行端检测到目标对象的绝缘阻值数据R低于预设绝缘阻值阈值R_lim，并且持续时间超过预设持续时长阈值，则说明目标对象当前时刻出现了异常现象，可能是电力系统出现异常情况，也可能是监测设备出现异常情况，需要进一步进行检测，此时为了保证用户的安全，可以输出关于绝缘阻值过低的告警提示信息。Among them, the preset insulation resistance threshold and the preset duration threshold can be configured according to the design data of the target object, and can also be configured after statistics on historical accident records. In the embodiment of this application, when the current execution end detects that the insulation resistance data R of the target object is lower than the preset insulation resistance threshold R_lim and the duration exceeds the preset duration threshold, it means that the target object is abnormal at the current moment. The phenomenon may be an abnormality in the power system or an abnormality in the monitoring equipment, which requires further detection. At this time, in order to ensure the safety of the user, an alarm message about the low insulation resistance can be output.

需要说明的是，信息的输出方式可以采用在仪表盘上亮起警示灯的方式，也可以采用发出警报铃声的方式，还可以将告警提示信息远程发送用户的移动设备，本申请实施例不做具体限定。It should be noted that the information output method can be by turning on the warning light on the dashboard, or by sending out an alarm ringtone, and the alarm prompt information can also be remotely sent to the user's mobile device, which is not covered in the embodiment of this application. Specific limits.

103、基于告警提示信息，触发绝缘故障诊断线程，以对目标对象进行绝缘故障诊断。103. Trigger an insulation fault diagnosis thread based on the alarm prompt information, so as to perform insulation fault diagnosis on the target object.

其中，绝缘故障诊断线程是根据预先建立的绝缘故障识别矩阵生成的，可以根据目标对象的设计数据进行配置，还可以通过对历史事故记录进行统计后配置。本申请实施例中，当输出告警提示信息时，说明目标对象在当前时刻存在异常情况，可能是电力系统出现异常情况，也可能是监测设备出现异常情况，需要触发绝缘故障诊断线程对目标对象进行绝缘故障诊断，以进一步确定具体的异常问题。Among them, the insulation fault diagnosis thread is generated according to the pre-established insulation fault identification matrix, which can be configured according to the design data of the target object, and can also be configured after statistics of historical accident records. In the embodiment of the present application, when the alarm prompt information is output, it indicates that the target object has an abnormal situation at the current moment, which may be an abnormal situation in the power system, or an abnormal situation in the monitoring equipment, and it is necessary to trigger the insulation fault diagnosis thread to perform Insulation fault diagnosis to further identify specific abnormal problems.

与现有技术相比，本申请实施例通过对目标对象的绝缘组织进行实时监测，当监测到低于预设绝缘阻值阈值时，输出告警信息的同时触发根据预先建立的绝缘故障识别矩阵生成的绝缘故障诊断线程，以对目标对象进行绝缘故障诊断，实现了绝缘故障的自动诊断，保证了安全的同时节省了用户因等人工进行故障处理所消耗的时长，还降低了排查故障所耗费的时间成本以及人工成本，提高了用户的体验感。Compared with the prior art, the embodiment of the present application monitors the insulation tissue of the target object in real time, and when it is detected to be lower than the preset insulation resistance threshold, the alarm information is output and at the same time triggers the generation of the insulation fault identification matrix based on the pre-established The insulation fault diagnosis thread of the target object is used to diagnose the insulation fault, which realizes the automatic diagnosis of the insulation fault, ensures safety and saves the time spent by users waiting for manual fault handling, and also reduces the time spent on troubleshooting. Time cost and labor cost improve the user experience.

本申请实施例提供了另一种绝缘故障的诊断方法，如图2所示，该方法包括：The embodiment of the present application provides another insulation fault diagnosis method, as shown in Figure 2, the method includes:

201、获取目标对象在当前时刻之前预设监测时长内的多个绝缘阻值数据。201. Obtain a plurality of insulation resistance data of a target object within a preset monitoring period before the current moment.

本申请实施例中，由于导致绝缘阻值过低的原因除了电力系统真正出现绝缘故障之外，还有可能是因为监测设备出现监测异常的情况，因此，在输出绝缘阻值过低的告警提示信息后，在保证安全的前提下，再次对造成告警提示的原因进行诊断，首先需要获取目标对象在当前时刻之前预设监测时长内的多个绝缘阻值数据，可以是在预设监测时长内所记录的全量时刻的绝缘阻值数据，也可以是预先配置间隔时长周期性获取的多个绝缘阻值数据，本申请实施例不做具体限定。In the embodiment of the present application, in addition to the real insulation fault in the power system, the reason for the low insulation resistance may also be the abnormal monitoring of the monitoring equipment. Therefore, when the output insulation resistance is too low, the alarm prompt After information, on the premise of ensuring safety, diagnose the cause of the alarm again. First, you need to obtain multiple insulation resistance data of the target object within the preset monitoring time before the current moment, which can be within the preset monitoring time. The recorded insulation resistance data at all times may also be a plurality of insulation resistance data obtained periodically at a preconfigured interval, which is not specifically limited in this embodiment of the present application.
