Abstract
Description
Technical Field
[0001] The present application relates to the field of vehicle detection technology, and in particular to a method, device and storage medium for detecting abnormal wear of a rail vehicle catenary. Background Art
[0002] The pantograph-catenary current collection system provides electrical power for rail vehicles. The carbon slide plate and contact wire are the main components that interact with each other during the current collection process. Their wear status is the main indicator parameter for vehicle maintenance. During vehicle maintenance, the carbon slide plate and contact wire need to be replaced regularly according to their wear.
[0003] At present, the wear of carbon slide plates and contact wires is usually detected by regular manual inspection with a vernier caliper. However, this method is labor-intensive, inconvenient for data statistics, and cannot provide early warning when abnormal wear occurs. Moreover, if abnormal wear occurs between two maintenance cycles, the abnormal situation cannot be discovered in time, causing further deterioration of wear, directly causing a bow-net accident and affecting vehicle operation.
[0004] In addition, in the prior art, the wear of the carbon slide plate can also be measured in real time by using an optical fiber sensor. However, the optical fiber sensor obtains signals through a single optical fiber that has been worn off. This makes the sensor non-reusable, which directly increases the cost of practical applications. Summary of the invention

[0059] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work belongs to the scope of protection of the present application.
[0060] The pantograph-catenary current collection system provides electrical power for rail vehicles. The carbon slide plate and contact wire are the main components that interact with each other during the current collection process. Their wear status is the main indicator parameter for vehicle maintenance. During vehicle maintenance, the carbon slide plate and contact wire need to be replaced regularly according to their wear.
[0061] At present, the wear of carbon slide plates and contact wires is usually detected by regular manual inspection with a vernier caliper. However, this method is labor-intensive, inconvenient for data statistics, and cannot provide early warning when abnormal wear occurs. Moreover, if abnormal wear occurs between two maintenance cycles, the abnormal situation cannot be discovered in time, causing further deterioration of wear, directly causing a bow-net accident and affecting vehicle operation.
[0062] In addition, in the prior art, the wear of the carbon slide plate can also be measured in real time by using an optical fiber sensor. However, the optical fiber sensor obtains signals through a single optical fiber that has been worn off. This makes the sensor non-reusable, which directly increases the cost of practical applications.
[0063] Based on this, the embodiments of the present application provide a method, device and storage medium for detecting abnormal wear of a rail vehicle bow and catenary. Through the designed detection device, the degree of wear of the bow and catenary can be detected in real time during the operation of the vehicle, thereby ensuring the safety of the vehicle driving. The device can also be reused, reducing the detection cost.
[0064] See also Figure 1 , Figure 1 A flow chart of a method for detecting abnormal wear of a rail vehicle bow net provided in an embodiment of the present application. The detection method is applied to a detection device for abnormal wear of a rail vehicle bow net, and the detection device includes a roughness detection component, a wireless receiving module, a data processing module, and a data interface. The data processing module is connected to the roughness detection component through the wireless receiving module, and the data processing module is also connected to the data interface, which is an interface for outputting data to the data connection line during data transmission.
[0065] like Figure 1 As shown in, the detection method provided in the embodiment of the present application includes:
[0066] S101. For each detection point during the travel of the target rail vehicle, the roughness detection component detects the roughness of the carbon slide board of the target rail vehicle at the current detection point, and sends the detected roughness of the carbon slide board at the current detection point to the data processing module through the wireless receiving module.
[0067] Here, the rail vehicle refers to a vehicle that relies on a pantograph system to provide power and electrical energy for travel, such as a high-speed train, a motor vehicle, a subway, and a tram.
[0068] The detection points are pre-set, for example, the stations passed along the way can be determined as detection points, or a detection point can be set at a certain interval on the driving route.
[0069] The roughness detection component can be a sensor capable of measuring roughness. The roughness detection component can be directly installed directly above the carbon slide plate to be detected and move with the target vehicle; or it can be installed at a detection point, and when the vehicle drives to the detection point or stops at the detection point, the roughness of the carbon slide plate on the target vehicle is detected.
[0070] Here, the roughness of the carbon slide plate is used to characterize the wear degree of the pantograph.
[0071] The wireless transceiver module and the data processing module are installed in an in-vehicle electrical cabinet of the target vehicle and are powered by an internal power supply unit of the target vehicle.
[0072] There can be at least one roughness detection component. When there are multiple pantographs on the target vehicle, there can be the same number of roughness detection components as the number of pantographs, and one roughness detection component is responsible for detecting the roughness of one pantograph carbon slide. One roughness detection component can also be used to detect the roughness of multiple pantograph carbon slides, but when sending the carbon slide roughness information to the data processing module, the identification information of the detected carbon slide is also sent, so as to subsequently confirm which carbon slide has an abnormality.
[0073] In one embodiment provided in the present application, the detection device also includes a data transmission module, which sends the detected roughness of the carbon skateboard at the current detection point to the data processing module through the wireless receiving module, including: the roughness detection component sends the detected roughness of the carbon skateboard at the current detection point to the data transmission module; the data transmission module sends the roughness of the carbon skateboard at the current detection point to the data processing module through the wireless receiving module.
[0074] Here, the roughness of the carbon skateboard at the current detection point detected by the roughness detection component can be sent directly to the data processing module through the wireless receiving module by the roughness detection component; or the roughness detection component can first send the detected roughness of the carbon skateboard at the current detection point to the data transmission module, and then the data transmission module sends the roughness of the carbon skateboard at the current detection point to the data processing module through the wireless receiving module.
[0075] Wherein, the data transmission module is installed on the roof of the target rail vehicle, or installed adjacent to the roughness detection component.
[0076] S102. The data processing module determines whether the amount of wear on the catenary of the target rail vehicle at the current detection point is abnormal based on the roughness of the carbon slide plate at the current detection point and a preset roughness threshold.
[0077] In one embodiment provided in the present application, the determination of whether the bow and catenary wear of the target rail vehicle at the current detection point is abnormal is based on the roughness of the carbon slide plate at the current detection point and a preset roughness threshold, including: when the roughness of the carbon slide plate at the current detection point is greater than or equal to the preset roughness threshold, determining that the bow and catenary wear of the target rail vehicle at the current detection point is abnormal; when the roughness of the carbon slide plate at the current detection point is not greater than the preset roughness threshold, determining that the bow and catenary wear of the target rail vehicle at the current detection point is not abnormal.
[0078] Here, the data processing module compares the roughness of the carbon slide plate at the current detection point detected by the roughness detection component with the preset roughness threshold. When the detected roughness is greater than or equal to the preset roughness threshold, it is determined that the bow and catenary wear of the target rail vehicle at the current detection point is abnormal. When the detected roughness is not greater than the preset roughness threshold, it is determined that the bow and catenary wear of the target rail vehicle at the current detection point is not abnormal.
[0079] S103. When it is determined that the bow-net wear is abnormal, the data processing module feeds back the detection result of the abnormal bow-net wear at the current detection point to the target supervisor through the data interface.
[0080] Here, when the data processing module determines that the bow net wear amount of the bow net being detected at the current detection point is abnormal, the abnormal result can be fed back to the target supervisor so that the supervisor can notify the relevant maintenance personnel to deal with the abnormal situation as soon as possible to prevent the abnormal fault from further spreading.
[0081] The target supervisor may be a driver or a safety supervisor.
[0082] S104. When it is determined that the bow-net wear is not abnormal, the data processing module determines whether the bow-net wear change rate of the target rail vehicle at the current detection point is abnormal based on the roughness of the carbon slide plate at the current detection point, the roughness of the carbon slide plate at the previous detection point, the distance between the two detection points and the preset roughness change threshold.
[0083] Here, after determining that the pantograph wear amount at the current detection point is not abnormal, it is also necessary to determine whether the pantograph wear change rate of the target rail vehicle at the current detection point is abnormal. It should be noted that only when both are not abnormal can it be determined that the pantograph wear of the target rail vehicle is not abnormal.
[0084] In one implementation provided in the present application, the data processing module pre-acquires route information on which the target rail vehicle is about to travel, wherein the route information includes distance information between adjacent detection points.
[0085] In one embodiment provided in the present application, the determination of whether the bow-net wear change rate of the target rail vehicle at the current detection point is abnormal is based on the roughness of the carbon slide board at the current detection point, the roughness of the carbon slide board at the previous detection point, the distance between the two detection points and a preset roughness change threshold, including: using the roughness of the carbon slide board at the current detection point minus the roughness of the carbon slide board at the previous detection point to determine the roughness difference of the carbon slide board at the current detection point; using the roughness difference of the carbon slide board at the current detection point divided by the distance between the two detection points to determine the bow-net wear change rate at the current detection point; when the bow-net wear change rate is greater than or equal to the preset roughness change threshold, determining that the bow-net wear change rate of the target rail vehicle at the current detection point is abnormal; when the bow-net wear change rate is not greater than the preset roughness change threshold, determining that the bow-net wear change rate of the target rail vehicle at the current detection point is not abnormal.
[0086] Here, it should be noted that when the current detection point is the starting detection point, it is directly determined that the pantograph wear change rate of the target rail vehicle at the current detection point is not abnormal.
[0087] S105. When it is determined that the bow-net wear change rate is abnormal, the data processing module feeds back the detection result of the abnormal bow-net wear change rate at the current detection point to the target supervisor through the data interface.
[0088] In one embodiment provided in the present application, when it is determined that the bow-catcher wear change rate is abnormal, the detection method further includes: determining the bow-catcher wear level of the target rail vehicle at the current detection point based on the bow-catcher wear change rate and preset wear level classification rules, and the data processing module feeds back the bow-catcher wear level of the current detection point to the target supervisor through the data interface.
[0089] Here, when the data processing module feeds back the abnormal change rate of the bow and catenary wear of the target rail vehicle at the current detection point to the target supervisor through the data interface, the bow and catenary wear level is also fed back. The bow and catenary wear level is used to assist the relevant maintenance personnel in determining the timing and priority of handling abnormal faults.
[0090] For example, the pantograph wear level may be: severe abnormality, moderate abnormality, mild abnormality. Or it may be: level 1, level 2, level 3, ... level N (the larger the value, the more serious the abnormality). The pantograph wear level may be determined adaptively and is not limited here.
[0091] In another embodiment provided in the present application, the detection device also includes a power supply conversion module, and the detection method also includes: the power supply conversion module converts the high voltage in the bow network into the working voltage of the roughness detection component and supplies power to the roughness detection component.
[0092] Here, the working voltage required for the roughness detection component to work is a low voltage, so the power supply module converts the high voltage in the bow net into a low voltage.
[0093] A method for detecting abnormal wear of a rail vehicle bow net provided in an embodiment of the present application, the detection method is applied to a detection device for abnormal wear of a rail vehicle bow net, the detection device comprising a roughness detection component, a wireless receiving module, a data processing module and a data interface, the detection method comprising: for each detection point in the travel process of a target rail vehicle, the roughness detection component detects the roughness of a carbon skateboard of the target rail vehicle at the current detection point, and sends the detected roughness of the carbon skateboard at the current detection point to the data processing module through the wireless receiving module; the data processing module determines the roughness of the carbon skateboard at the current detection point based on the roughness of the carbon skateboard at the current detection point and a preset roughness threshold; whether the bow and net wear of the target rail vehicle is abnormal; when it is determined that the bow and net wear is abnormal, the data processing module feeds back the detection result of the abnormal bow and net wear at the current detection point to the target supervisor through the data interface; when it is determined that the bow and net wear is not abnormal, the data processing module determines whether the bow and net wear change rate of the target rail vehicle at the current detection point is abnormal based on the roughness of the carbon slide board at the current detection point, the roughness of the carbon slide board at the previous detection point, the distance between the two detection points and the preset roughness change threshold; when it is determined that the bow and net wear change rate is abnormal, the data processing module feeds back the detection result of the abnormal bow and net wear change rate at the current detection point to the target supervisor through the data interface.
[0094] In this way, based on the technical solution provided in this application, the detection device designed by this solution can perform real-time detection of the wear degree of the bow net during the operation of the vehicle and discover abnormal conditions in time, thereby ensuring the safety of vehicle driving. The device can also be reused, reducing the detection cost.

[0101] The roughness difference of the carbon slide board at the current detection point is determined by subtracting the roughness of the carbon slide board at the previous detection point from the roughness of the carbon slide board at the current detection point;
[0102] The roughness difference of the carbon slide plate at the current detection point is divided by the distance between the two detection points to determine the wear change rate of the pantograph at the current detection point;
