[0002] The overhead contact network is the core component of the electric traction power supply system. It is erected above the track through pillars and arms to supply power to electric locomotives. As the overhead contact network is exposed to various natural environments all year round, it is greatly affected by the external environment. Under weather conditions such as low temperature, rain, snow and freezing, once the overhead contact network wires are covered with ice, the pantograph's contact current collection performance will decrease, and the power supply reliability will also decrease. In severe cases, it may cause the train to be unable to draw current and run normally, posing a major hidden danger to the safe operation of the railway.

[0003] In order to ensure the safe operation of the railway, it is necessary to promptly and effectively remove the ice on the contact network wires.

[0023] In order to more clearly understand the above objects, features and advantages of the present disclosure, the solutions of the present disclosure will be further described below. It should be noted that, without conflict, the embodiments of the present disclosure and the features in the embodiments may be combined with each other.

[0024] In the following description, many specific details are set forth to fully understand the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only a part of the embodiments of the present disclosure, rather than all of the embodiments.

[0025] It should be understood that the steps recorded in the method embodiments of the present disclosure may be executed in different orders and / or executed in parallel. In addition, the method embodiments may include additional steps and / or omit the steps shown. The scope of the present disclosure is not limited in this regard.

[0026] Figure 1 It is a flowchart of an ice melting method based on ice coating thickness provided by an embodiment of the present disclosure. This method can be executed by an ice melting device based on ice coating thickness. The ice melting device based on ice coating thickness can be implemented in a software and / or hardware manner. The ice melting device based on ice coating thickness can be configured in an electronic device, such as a server or a terminal. Among them, the terminal specifically includes a mobile phone, a computer, a tablet computer, etc. As Figure 1 shown, the ice melting method based on ice coating thickness provided in this embodiment includes the following steps:

[0027] S101. Monitor the ice coating thickness of the catenary wire.

[0028] The catenary wire in the embodiments of the present disclosure can be understood as a wire component in the catenary that can apply current and eliminate ice coating by the DC ice melting method. For example, the catenary wire may include a contact wire and a carrier cable.

[0029] In the embodiments of the present disclosure, the ice melting device based on ice coating thickness can, after receiving the catenary ice melting task, monitor the ice coating thickness of the catenary wire in real time.

[0030] In an exemplary implementation manner of the embodiments of the present disclosure, the ice melting device based on the ice coating thickness may obtain the weather information of the area where the catenary is located, and determine whether there is an ice coating risk on the catenary according to the weather information. If so, an ice melting task for the catenary is created, and the ice coating thickness of the catenary conductor is monitored. Optionally, the ice melting device based on the ice coating thickness may also determine the frequency of obtaining relevant information when monitoring the ice coating thickness according to the ice coating risk level of the catenary. The higher the ice coating risk, the higher the frequency of obtaining relevant information.

[0031] In another exemplary implementation manner of the embodiments of the present disclosure, when the ice melting device based on the ice coating thickness monitors the ice coating thickness of the catenary conductor, it may obtain the three-dimensional point cloud data of the catenary conductor, determine the overall radius of the catenary conductor after ice coating according to the three-dimensional point cloud data, and calculate the ice coating thickness of the catenary conductor based on the radius of the catenary conductor in the non-ice-coated state obtained in advance.

[0032] S102. In response to the ice coating thickness reaching the pre-obtained ice melting interval, perform a DC ice melting operation based on the preset ice melting parameters. The ice melting interval is the ice coating thickness interval in which the ice melting efficiency is higher than the preset threshold when performing the DC ice melting operation using the preset ice melting parameters.

[0033] The ice melting interval in the embodiments of the present disclosure can be understood as the ice coating thickness interval in which the ice melting efficiency is higher than the preset threshold when performing the DC ice melting operation using the preset ice melting parameters. Since during the DC ice melting process of the catenary, the heat generated by the current needs a certain amount of time to spread to the ice coating surface, the increase in the ice coating radius will cause slower heat transfer, thereby increasing heat accumulation. At the same time, the increase in the ice coating radius will also increase the contact area between the ice coating surface and the air, resulting in an increase in the convective heat transfer area, and will also increase the heat absorbed by the ice layer during the ice melting process, thereby reducing heat accumulation. And the heat accumulation situation will affect the ice melting efficiency, resulting in a non-monotonic change form in the relationship between the ice melting efficiency and the ice coating thickness. Starting to melt ice within a certain ice coating thickness interval can make the ice melting efficiency higher than the preset threshold, and it is determined as the ice melting interval.

[0034] The ice melting parameters in the embodiments of the present disclosure can be understood as the control parameters when performing the DC ice melting operation. The specific values of the ice melting parameters can be set according to experience. Optionally, the ice melting parameters may include current parameters, and may also include duration parameters, voltage parameters, etc., which are not limited herein.

[0035] In the embodiments of the present disclosure, after the ice melting device based on the ice coating thickness monitors that the ice coating thickness of the catenary conductor reaches the ice melting interval where the ice melting efficiency is higher than the preset threshold, an ice melting current is applied to the catenary wire according to the preset ice melting parameters, and a DC ice melting operation is performed.

[0036] In an exemplary implementation manner of the embodiments of the present disclosure, during the execution of the DC ice melting operation, the ice melting device based on the ice thickness can continue to monitor the ice thickness of the catenary conductor until the ice on the catenary conductor is completely eliminated or the ice thickness reaches a preset safety value.

[0037] In the embodiments of the present disclosure, by monitoring the ice thickness of the catenary conductor and in response to the ice thickness reaching a pre-obtained ice melting range, a DC ice melting operation is performed based on preset ice melting parameters. The ice melting range is an ice thickness range in which the ice melting efficiency is higher than a preset threshold when performing the DC ice melting operation using the preset ice melting parameters. It can monitor the ice thickness on the catenary conductor in real time and perform the DC ice melting operation when it is monitored that the ice thickness reaches the pre-obtained ice melting range with a higher ice melting efficiency, thereby improving the ice melting efficiency of the catenary.

[0038] Figure 2 is a flowchart of a method for determining the ice thickness provided by the embodiments of the present disclosure. As Figure 2 shown, based on the above embodiments, the ice thickness can be determined by the following method.

[0039] S201. Obtain the ice-covered image of the catenary conductor.

[0040] In the embodiments of the present disclosure, the ice melting device based on the ice thickness can obtain the ice-covered image of the catenary conductor collected by an image acquisition device, such as a camera, arranged around the catenary conductor.

[0041] In an exemplary implementation manner of the embodiments of the present disclosure, after receiving the catenary ice melting task, the ice melting device based on the ice thickness can send a control instruction to the image acquisition device to enable the image acquisition device to start collecting the ice-covered image of the catenary conductor and return the collected ice-covered image to the ice melting device based on the ice thickness. Optionally, the control instruction may include the acquisition frequency of the ice-covered image.

[0042] S202. Perform image recognition on the ice-covered image to determine the average distance between the outer surface of the ice layer and the center point of the catenary conductor.

[0043] In the embodiments of the present disclosure, after obtaining the ice-covered image of the catenary conductor, the ice melting device based on the ice thickness can perform image recognition processing on the ice-covered image. Specifically, an edge detection algorithm can be used to extract the edge contours of the catenary conductor and the ice layer. According to the recognized edge contours of the catenary conductor and the ice layer, the coordinates of the center point of the catenary conductor are determined, and then the pixel distances between the points on the outer surface of the ice layer and the center point of the catenary conductor are determined. Combining the internal and external parameters of the image acquisition device, the actual distances between the points on the outer surface of the ice layer and the center point of the catenary conductor are calculated, and the average of the actual distances is obtained to get the average distance between the outer surface of the ice layer and the center point of the catenary conductor.

[0044] In an exemplary implementation of the embodiments of the present disclosure, after determining the center point of the catenary conductor, the ice melting device based on the ice thickness can establish a polar coordinate system with the center point of the catenary conductor as the origin and obtain the distance from the points on the outer surface of the ice layer to the center point. , and the average distance between the outer surface of the ice layer and the center point of the catenary conductor is .

[0045] S203. Calculate the ice thickness of the catenary conductor based on the average distance and the radius of the catenary conductor obtained in advance.

[0046] In the embodiments of the present disclosure, after determining the average distance between the outer surface of the ice layer and the center point of the catenary conductor, the ice melting device based on the ice thickness can calculate the difference between the average distance and the radius of the catenary conductor obtained in advance to obtain the ice thickness of the catenary conductor.

[0047] In the embodiments of the present disclosure, by acquiring the ice-covered image of the catenary conductor, performing image recognition on the ice-covered image to determine the average distance between the outer surface of the ice layer and the center point of the catenary conductor, and calculating the ice thickness of the catenary conductor based on the average distance and the radius of the catenary conductor obtained in advance, the accuracy of monitoring the ice thickness can be improved, and thus the efficiency of catenary ice melting can be further improved based on the accurate ice thickness.

[0048] Figure 3 is a flowchart of a method for determining the ice melting interval provided by the embodiments of the present disclosure. As Figure 3 shown, on the basis of the above embodiments, the ice melting interval can be determined by the following method.

[0049] S301. Perform DC ice melting operations on at least two groups of catenary conductors with different ice thicknesses based on preset ice melting parameters.

[0050] In the embodiments of the present disclosure, the ice melting device based on the ice thickness can adopt preset ice melting parameters to perform DC ice melting operations on at least two groups of catenary conductors with different ice thicknesses prepared in advance. For example, the values of the ice thickness of at least two groups of catenary conductors can be 2 mm - 30 mm, and the difference between adjacent ice thicknesses can be 1 mm, which is not limited herein.

[0051] Among them, the initial ice layer temperatures corresponding to at least two groups of catenary conductors are the same. Specifically, the ice melting device based on the ice thickness can obtain the cross-sectional temperature distribution through infrared temperature measurement , the ice layer temperature , S represents the cross-sectional area of the catenary conductor, and further ensure that the initial ice layer temperatures corresponding to each group of catenary conductors are the same before performing the DC ice melting operation.

[0052] In an exemplary implementation manner of the embodiments of the present disclosure, the ice melting device based on the ice coating thickness can ensure that the ambient temperatures of the environments where each group of catenary conductors are located are the same before performing the DC ice melting operation.

[0053] S302. Monitor the surface temperature values of at least two groups of catenary conductors to obtain the maximum temperature values respectively corresponding to at least two groups of catenary conductors during the execution of the DC ice melting operation.

[0054] In the embodiments of the present disclosure, the ice melting device based on the ice coating thickness can, during the process of performing the DC ice melting operation on at least two groups of catenary conductors, monitor and record the surface temperature values of at least two groups of catenary conductors within a preset time period, and perform statistical analysis on the surface temperature value data corresponding to each group of catenary conductors to obtain the maximum temperature values respectively corresponding to each group of catenary conductors.

[0055] Specifically, when each group of catenary conductors is not ice-coated, a temperature sensor, such as a chip resistor sensor, can be attached to the surface of the catenary conductor, and the ice melting device based on the ice coating thickness can obtain the surface temperature value of the catenary conductor collected by the temperature sensor.

[0056] S303. Determine the ice melting interval based on the target ice coating thickness corresponding to the group of catenary conductors with the highest maximum temperature value among at least two groups of catenary conductors.

[0057] The target ice coating thickness in the embodiments of the present disclosure can be understood as the ice coating thickness with the highest ice melting efficiency among the respective ice coating thicknesses corresponding to at least two groups of catenary conductors participating in the test.

[0058] In the embodiments of the present disclosure, the ice melting device based on the ice coating thickness can, after obtaining the maximum temperature values respectively corresponding to each group of catenary conductors, sort the respective maximum temperature values to determine the highest maximum temperature value, and determine the ice coating thickness corresponding to the group of catenary conductors with the highest maximum temperature value as the target ice coating thickness, and then determine the ice melting interval according to the target ice coating thickness.

[0059] Optionally, the ice melting device based on the ice coating thickness can determine the ice melting interval based on the target ice coating thickness and a preset floating range.

[0060] Specifically, the ice melting device based on the ice coating thickness can, after determining the target ice coating thickness, determine the ice melting thickness within the preset floating range above and below the target ice coating thickness as the ice melting interval. For example, when the target ice coating thickness is 3 mm and the preset floating range is ±1 mm, the ice melting interval d can be 2 mm ≤ d ≤ 4 mm.

[0061] In the embodiments of the present disclosure, direct current de-icing operations are performed on at least two groups of catenary conductors with different ice coating thicknesses based on preset de-icing parameters, the surface temperature values of the at least two groups of catenary conductors are monitored, and the maximum temperature values respectively corresponding to the at least two groups of catenary conductors during the execution of the direct current de-icing operations are obtained. The de-icing interval is determined based on the target ice coating thickness corresponding to the group of catenary conductors with the highest maximum temperature value among the at least two groups of catenary conductors, which can improve the accuracy of determining the de-icing interval, and thus further improve the efficiency of catenary de-icing based on the accurate de-icing interval.
