DETAILED DESCRIPTION

[0014] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0015] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0016] It should be understood that the various steps described in the method embodiments of the present disclosure may be performed in different orders and / or 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 respect.

[0017] Figure 1 This is a flow chart of an ice melting method based on ice thickness provided by an embodiment of the present disclosure. The method can be executed by an ice melting device based on ice thickness. The ice melting device based on ice thickness can be implemented in software and / or hardware. The ice melting device based on ice thickness can be configured in an electronic device, such as a server or a terminal, wherein the terminal specifically includes a mobile phone, a computer or a tablet computer, etc. Figure 1 As shown, the ice melting method based on ice thickness provided in this embodiment includes the following steps: S101. Monitor the ice thickness of the contact network wires.

[0018] The overhead contact wire in the embodiment of the present disclosure may be understood as a wire component in the overhead contact wire component that can apply current and remove ice through a direct current ice melting method. For example, the overhead contact wire may include a contact wire and a load-bearing cable.

[0019] In the disclosed embodiment, the ice melting device based on ice thickness can monitor the ice thickness of the contact network conductor in real time after receiving the contact network ice melting task.

[0020] In an exemplary implementation of the disclosed embodiment, an ice-melting device based on ice thickness can obtain weather information in the area where the contact network is located, and determine whether there is an icing risk for the contact network based on the weather information. If so, a contact network ice-melting task is created, and the ice thickness of the contact network conductors is monitored. Optionally, the ice-melting device based on ice thickness can also determine the frequency of obtaining relevant information when monitoring the ice thickness based on the icing risk level of the contact network. The higher the icing risk, the higher the frequency of obtaining relevant information.

[0021] In another exemplary implementation of the disclosed embodiment, an ice melting device based on ice thickness can obtain three-dimensional point cloud data of the contact network conductor when monitoring the ice thickness of the contact network conductor, determine the overall radius of the contact network conductor after ice coating according to the three-dimensional point cloud data, and calculate the ice thickness of the contact network conductor according to the pre-acquired radius of the contact network conductor in the un-iced state.

[0022] S102: In response to the ice thickness reaching a pre-acquired ice melting interval, a direct current ice melting operation is performed based on preset ice melting parameters, where the ice melting interval is an ice thickness interval in which an ice melting efficiency is higher than a preset threshold when the direct current ice melting operation is performed using the preset ice melting parameters.

[0023] The ice melting interval in the embodiment of the present disclosure can be understood as an ice thickness interval in which the ice melting efficiency is higher than a preset threshold value when the DC ice melting operation is performed using preset ice melting parameters. During the DC ice melting process of the contact network, the heat generated by the current requires a certain amount of time to diffuse to the ice surface. An increase in the ice radius will result in slower heat transfer, thereby increasing heat accumulation. At the same time, an increase in the ice radius will also increase the contact area between the ice 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. The heat accumulation will affect the ice melting efficiency, resulting in the relationship between the ice melting efficiency and the ice thickness presenting a non-monotonic change. Starting to melt ice within a certain ice thickness interval can make the ice melting efficiency higher than the preset threshold, which is determined as the ice melting interval.

[0024] The ice melting parameters in the embodiments of the present disclosure may be understood as control parameters when performing DC ice melting operations. The specific values ​​of the ice melting parameters may be set based on experience. Optionally, the ice melting parameters may include current parameters, duration parameters, voltage parameters, etc., which are not limited here.

[0025] In the embodiment of the present disclosure, the ice melting device based on ice thickness can apply ice melting current to the contact network to the line according to pre-set ice melting parameters after monitoring that the ice thickness of the contact network conductor reaches an ice melting interval in which the ice melting efficiency is higher than a preset threshold, and perform a DC ice melting operation.

[0026] In an exemplary implementation of the disclosed embodiment, the ice-melting device based on ice thickness can continue to monitor the ice thickness of the contact network conductor during the DC ice melting operation until the ice on the contact network conductor is completely eliminated or the ice thickness reaches a preset safety value.

[0027] The embodiment of the present disclosure monitors the ice thickness of the contact network conductor, and in response to the ice thickness reaching a pre-acquired ice-melting interval, performs a DC ice-melting operation based on preset ice-melting parameters. The ice-melting interval is an ice thickness interval in which the ice-melting efficiency is higher than a preset threshold when the DC ice-melting operation is performed using the preset ice-melting parameters. The ice thickness on the contact network conductor can be monitored in real time, and when it is monitored that the ice thickness reaches a pre-acquired ice-melting interval with a higher ice-melting efficiency, a DC ice-melting operation is performed, thereby improving the efficiency of ice-melting in the contact network.

[0028] Figure 2 is a flow chart of a method for determining ice thickness provided by an embodiment of the present disclosure, such as Figure 2 As shown, based on the above embodiment, the ice thickness can be determined by the following method.

[0029] S201, obtaining an image of ice coating on overhead wires.

[0030] In the disclosed embodiment, the ice melting device based on the ice coating thickness can obtain an image of ice coating on the contact network conductor captured by an image acquisition device arranged around the contact network conductor, such as a camera.

[0031] In an exemplary implementation of the disclosed embodiment, the ice-melting device based on ice thickness may send a control instruction to the image acquisition device after receiving a contact network ice-melting task, so that the image acquisition device starts to acquire ice-covered images of the contact network wires, and returns the acquired ice-covered images to the ice-melting device based on ice thickness. Optionally, the control instruction may include an acquisition frequency of the ice-covered images.

[0032] 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 contact network conductor.

[0033] In the embodiment of the present disclosure, the ice melting device based on ice thickness can perform image recognition processing on the ice image after acquiring the ice image of the contact network conductor. Specifically, an edge detection algorithm can be used to extract the edge contours of the contact network conductor and the ice layer. According to the identified edge contours of the contact network conductor and the ice layer, the coordinates of the center point of the contact network conductor are determined, and then the pixel distance between each point on the outer surface of the ice layer and the center point of the contact network conductor is determined. The actual distance between each point on the outer surface of the ice layer and the center point of the contact network conductor is calculated in combination with the internal and external parameters of the image acquisition device, and the actual distance is averaged to obtain the average distance between the outer surface of the ice layer and the center point of the contact network conductor.

[0034] In an exemplary implementation of the embodiment of the present disclosure, the ice melting device based on the ice thickness can establish a polar coordinate system with the center point of the contact wire as the origin after determining the center point of the contact wire, and obtain the distance from the point on the outer surface of the ice layer to the center point. , the average distance between the outer surface of the ice layer and the center point of the contact wire is .

[0035] S203: Calculate the ice thickness of the contact network conductor based on the average distance and the radius of the contact network conductor obtained in advance.

[0036] In the embodiment of the present disclosure, the ice melting device based on ice thickness can determine the average distance between the outer surface of the ice layer and the center point of the contact network conductor, calculate the difference between the average distance and the radius of the contact network conductor obtained in advance, and obtain the ice thickness of the contact network conductor.

[0037] The disclosed embodiment acquires an image of ice coating on the contact network conductor, performs image recognition on the image of ice coating, determines the average distance between the outer surface of the ice layer and the center point of the contact network conductor, and calculates the ice coating thickness of the contact network conductor based on the average distance and the radius of the contact network conductor acquired in advance. This can improve the accuracy of monitoring the ice coating thickness, thereby further improving the efficiency of melting ice on the contact network based on the precise ice coating thickness.

[0038] Figure 3 is a flow chart of a method for determining an ice melting interval provided by an embodiment of the present disclosure, such as Figure 3 As shown, based on the above embodiment, the ice melting interval can be determined by the following method.

[0039] S301. Performing a DC ice-melting operation on at least two groups of overhead contact wires with different ice-covering thicknesses based on preset ice-melting parameters.

[0040] In the disclosed embodiment, the ice melting device based on ice coating thickness can adopt preset ice melting parameters to perform DC ice melting operations on at least two groups of contact network conductors with different ice coating thicknesses prepared in advance. By way of example, the ice coating thickness of at least two groups of contact network conductors can be 2mm-30mm, and the difference in adjacent ice coating thicknesses can be 1mm, which is not limited here.

[0041] Among them, the initial ice layer temperature corresponding to at least two groups of contact network wires is the same. Specifically, the ice melting device based on the ice thickness can obtain the cross-sectional temperature distribution through infrared temperature measurement. , ice temperature , S represents the cross-sectional area of ​​the overhead contact wire, and further ensures that the initial ice layer temperature corresponding to each group of overhead contact wires is the same before performing the DC ice melting operation.

[0042] In an exemplary implementation of the disclosed embodiment, the ice melting device based on ice thickness can ensure that the ambient temperature of the environment where each group of contact network conductors is located is the same before performing the DC ice melting operation.

[0043] S302: Monitor surface temperature values ​​of at least two groups of contact network conductors to obtain maximum temperature values ​​corresponding to the at least two groups of contact network conductors during the execution of the DC ice melting operation.

[0044] In the embodiment of the present disclosure, the ice melting device based on ice thickness can monitor and record the surface temperature values ​​of at least two groups of contact network conductors within a preset time period during the process of performing DC ice melting operations on at least two groups of contact network conductors, and perform statistical analysis on the surface temperature value data corresponding to each group of contact network conductors to obtain the maximum temperature values ​​corresponding to each group of contact network conductors.

[0045] Specifically, when each group of contact network wires is not covered with ice, a temperature sensor, such as a chip resistor sensor, can be attached to the surface of the contact network wire. An ice melting device based on the ice thickness can obtain the surface temperature value of the contact network wire collected by the temperature sensor.

[0046] S303: Determine the ice melting interval based on the target ice thickness corresponding to the group of contact network conductors having the highest maximum temperature value among at least two groups of contact network conductors.

[0047] The target ice thickness in the embodiment of the present disclosure may be understood as the ice thickness with the highest ice melting efficiency among the ice thicknesses corresponding to at least two groups of contact network conductors participating in the test.

[0048] In the embodiment of the present disclosure, the ice melting device based on ice thickness can sort the maximum temperature values ​​corresponding to each group of contact network conductors after obtaining them, determine the highest maximum temperature value, and determine the ice thickness corresponding to a group of contact network conductors with the highest maximum temperature value as the target ice thickness, and then determine the ice melting interval according to the target ice thickness.

[0049] Optionally, the ice melting device based on ice thickness may determine the ice melting interval based on a target ice thickness and a preset floating range.

[0050] Specifically, after determining the target ice thickness, the ice melting device based on the ice thickness can determine the ice melting interval based on the ice melting thickness within a preset floating range above and below the target ice thickness. For example, when the target ice thickness is 3 mm and the preset floating range is ±1 mm, the ice melting interval d can be 2 mm ≤ d ≤ 4 mm.

[0051] The disclosed embodiment performs a DC ice-melting operation on at least two groups of contact network conductors with different ice coating thicknesses based on preset ice-melting parameters, monitors the surface temperature values ​​of the at least two groups of contact network conductors, obtains the maximum temperature values ​​corresponding to the at least two groups of contact network conductors during the execution of the DC ice-melting operation, and determines the ice-melting interval based on the target ice coating thickness corresponding to the group of contact network conductors with the highest maximum temperature value among the at least two groups of contact network conductors. This can improve the accuracy of determining the ice-melting interval, thereby further improving the efficiency of contact network ice-melting based on the precise ice-melting interval.
