It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. Unless otherwise defined, all technical terms used hereinafter have the same meanings as commonly understood by those skilled in the art.
参见图1，一种本发明实施例的高速铁路大风防灾监测系统的故障检测方法，高速铁路大风防灾监测系统的结构如图2所示，其中包括两个风速仪。该故障检测方法包括以下步骤：以0时刻为起点，每10分钟作为一个检测周期；获取大风防灾监测系统中的风速仪在一个检测周期内多个时间节点时所测得的瞬时风速数据；对该风速仪测得的相邻时间节点的瞬时风速数据进行比较，当相邻时间节点的瞬时风速值差值超过设定值时，发出瞬时风速值差值超限报警，并提示该风速仪发生故障及故障发生时间。该高速铁路大风防灾监测系统的故障检测方法，能够快速、准确、可靠地对高速铁路大风防灾监测系统中风速仪故障进行检测，实现风速仪故障的精确定位。Referring to FIG. 1 , a fault detection method of a high-speed railway disaster prevention monitoring system according to an embodiment of the present invention, the structure of the high-speed railway disaster prevention monitoring system is shown in FIG. 2 , which includes two anemometers. The fault detection method includes the following steps: starting at time 0, and every 10 minutes as a detection cycle; acquiring instantaneous wind speed data measured by an anemometer in the gale disaster prevention monitoring system at multiple time nodes in a detection cycle; Compare the instantaneous wind speed data of adjacent time nodes measured by the anemometer, and when the difference between the instantaneous wind speed values of adjacent time nodes exceeds the set value, an alarm will be issued for the difference of instantaneous wind speed value exceeding the limit, and the anemometer will be prompted Failure and time of failure. The fault detection method of the high-speed railway high-wind disaster prevention monitoring system can quickly, accurately and reliably detect the fault of the anemometer in the high-speed railway high-wind disaster prevention monitoring system, and realize the precise positioning of the anemometer fault.
进一步地，在本实施例中，该故障检测方法还包括：将大风防灾监测系统中的两台风速仪在同一时间节点时所测得的瞬时风速数据进行比较，当同一时间节点时两台风速仪所测得的瞬时风速值的差值超过设定值时，则两台风速仪中至少有一台出现故障，此时发出两台风速仪瞬时风速值差值超限报警，并提示故障发生时间；然后分别将两台风速仪所测得的瞬时风速数据与相应风速仪的历史数据进行对比，确定具体出现故障的风速仪。Further, in this embodiment, the fault detection method further includes: comparing the instantaneous wind speed data measured by the two anemometers in the gale disaster prevention monitoring system at the same time node, and when the two anemometers are at the same time node When the difference between the instantaneous wind speed values measured by the anemometers exceeds the set value, at least one of the two anemometers is faulty. At this time, an alarm is issued for the difference between the instantaneous wind speed values of the two anemometers, and a fault occurs Then compare the instantaneous wind speed data measured by the two anemometers with the historical data of the corresponding anemometer to determine the specific anemometer that has failed.
正常情况下，同测点的两台风速仪在同一时间节点所测得的瞬时风速值是非常接近的，当其中某台风速仪出现故障，但是此台风速仪数据自检并未检测出故障的时候，通过上述方法对比两台风速仪在同一时间节点时的瞬时风速差值也可以检测出故障，起到互相补充的作用。Under normal circumstances, the instantaneous wind speed values measured by two anemometers at the same measuring point at the same time node are very close. When one of the anemometers fails, the data self-test of this anemometer does not detect the failure When using the above method to compare the instantaneous wind speed difference between the two anemometers at the same time node, the fault can also be detected, which complements each other.
进一步地，该故障检测方法还包括：当相邻时间节点的瞬时风速值差值未超过设定值时，将一个检测周期等分为多个时间段(如30秒)，每个时间段包括多个时间节点，计算每个时间段内大风防灾监测系统中的风速仪测得的平均风速值，比较相邻时间段内的平均风速值，当相邻时间段内的平均风速值差值超过设定值时，发出风速平均值差值超限报警，提示该风速仪发生故障及故障发生时间。Further, the fault detection method also includes: when the difference between instantaneous wind speed values at adjacent time nodes does not exceed the set value, dividing a detection cycle into multiple time periods (such as 30 seconds), each time period includes Multiple time nodes, calculate the average wind speed value measured by the anemometer in the gale disaster prevention monitoring system in each time period, compare the average wind speed value in adjacent time periods, when the average wind speed value difference in adjacent time periods When the set value is exceeded, an alarm will be issued to indicate that the anemometer has a fault and the time when the fault occurred.
平均风速值是表示一段时间内风特征的尺度之一，反映的是一段时间内风速值的平均值，若风速仪发生故障，可以平均风速值差值中得到很好的体现。本发明进一步通过上述方法比较相邻时间段内的平均风速值差值，能够更加准确、可靠地对高速铁路大风防灾监测系统中风速仪故障进行检测。The average wind speed value is one of the scales representing the wind characteristics within a period of time, reflecting the average value of the wind speed value within a period of time. If the anemometer fails, it can be well reflected in the difference of the average wind speed value. The present invention further compares the average wind speed value difference in adjacent time periods by the above method, and can more accurately and reliably detect the failure of the anemometer in the high-speed railway high-wind disaster prevention monitoring system.
在本实施例中，该故障检测方法还包括：将大风防灾监测系统中的两台风速仪在同一时间段内的平均风速值进行比较，当两台风速仪在同一时间段内的平均风速值差值超过设定值时，则至少有一台风速仪出现故障，发出两台风速仪平均风速值差值超限报警，并提示故障发生时间；然后分别将两台风速仪所测得的瞬时风速数据与相应风速仪的历史数据进行对比，确定具体出现故障的风速仪。In this embodiment, the fault detection method further includes: comparing the average wind speed values of the two anemometers in the gale disaster prevention monitoring system in the same time period, when the average wind speed values of the two anemometers in the same time period When the value difference exceeds the set value, at least one anemometer fails, and an alarm is issued for the difference between the average wind speed values of the two anemometers exceeding the limit, and the time of failure is prompted; then the instantaneous values measured by the two anemometers are respectively The wind speed data is compared with the historical data of the corresponding anemometer to determine the specific anemometer that has failed.
正常情况下，同测点的两台风速仪在同一时间节点所测得的平均风速值是非常接近的；当某台风速仪出现故障，但是此台风速仪数据自检并未检测出故障的时候，通过上述的方法对比两台风速仪的平均风速值差值也可以检测出故障，并且进一步分别将两台风速仪所测得的瞬时风速数据与相应风速仪的历史数据进行对比，可以确定出具体出现故障的风速仪。通过上述的方法，可以起到互相补充的作用，使故障检测更加准确、可靠。Under normal circumstances, the average wind speed values measured by two anemometers at the same measuring point at the same time node are very close; At this time, the fault can also be detected by comparing the difference between the average wind speed values of the two anemometers by the above method, and further comparing the instantaneous wind speed data measured by the two anemometers with the historical data of the corresponding anemometer, it can be determined that Identify the specific anemometer that failed. Through the above methods, they can complement each other and make fault detection more accurate and reliable.
