Description

Technical Field

[0001] This invention relates to the field of railway maintenance technology, and in particular to a control method and device for turnout heating equipment. Background Technology

[0002] Railway turnouts are crucial equipment for changing tracks for trains, using the left and right movement of the turnout switch rails to achieve track switching. During winter snowfall, snow accumulation in the turnout area can easily cause snow to get trapped between the turnout switch rails and the stock rails, affecting the movement of the switch rails and their contact with the stock rails, thus jeopardizing train safety. Electric snow-melting equipment for railway turnouts solves this problem by installing electric heating devices on the rails in the turnout area. The equipment melts the ice and snow by applying electricity, eliminating the potential hazard.

[0003] Currently, the conventional method for controlling heating equipment is to simultaneously start and stop all heating devices installed on all rails within the turnout area, with all operating at full power during startup. However, since the turnout area is mostly outdoors and the rails themselves are enormous, the heating equipment requires a huge amount of electrical power, resulting in significant energy consumption during the snow melting process. Summary of the Invention

[0004] In view of the above problems, the present invention provides a control method and device for turnout heating equipment, the main purpose of which is to reduce the power consumption during the snow melting process and reduce the cost of power use.

[0005] To solve the above-mentioned technical problems, the present invention proposes the following solution:

[0006] In a first aspect, the present invention provides a control method for a turnout heating device, applied to an intelligent power-on / off control module in a turnout snow melting control system. The intelligent power-on / off control module is used to control the heating device, and the method includes:

[0007] Determine the heating time corresponding to the target rail group, wherein the target rail group is any rail group located in the turnout area and on both sides of the rails that are equipped with the heating equipment;

[0008] Based on the heating duration, the heating equipment installed on both sides of the target rail group is controlled in turn to perform heating operations in a specified working mode so as to melt the snow on the rail surface of both sides of the target rail group.

[0009] Secondly, the present invention provides a control device for a turnout heating equipment, which is applied to an intelligent power-on / off control module in a turnout snow melting control system. The intelligent power-on / off control module is used to control the heating equipment, and the device includes:

[0010] The first determining unit is used to determine the heating time corresponding to the target rail group, wherein the target rail group is any rail group located in the turnout area and whose rails on both sides are equipped with heating devices.

[0011] The first control unit is configured to control the heating equipment installed on both sides of the target rail group to perform heating operations in a specified working mode based on the heating duration obtained by the first determining unit, so as to melt the snow covering the rail surface of both sides of the target rail group.

[0012] To achieve the above objectives, according to a third aspect of the present invention, a storage medium is provided, the storage medium including a stored program, wherein, when the program is executed, the device where the storage medium is located is controlled to perform the turnout heating device control method of the first aspect.

[0013] To achieve the above objectives, according to a fourth aspect of the present invention, a processor is provided for running a program, wherein the program executes the turnout heating device control method of the first aspect described above.

[0014] By means of the above technical solution, the present invention provides a control method and device for turnout heating equipment. When it is necessary to control the turnout heating equipment, the heating duration corresponding to the target rail group is first determined. The target rail group is any rail group located in the turnout area with heating equipment installed on both sides of the rails. Then, based on the heating duration, the heating equipment installed on both sides of the target rail group is controlled in turn to perform heating operations in a specified working mode so as to melt the snow on the rail surface of both sides of the target rail group. The technical solution provided by this invention allows for the selection of a heating duration, i.e., the start-up duration of the heating equipment. This start-up duration allows for the alternating control of the heating equipment installed on both sides of the target rail group, performing heating operations in a specified working mode. Specifically, the heating equipment on one side of the rail is first started to heat that side individually until the specified heating duration, then shut down. Simultaneously, the heating equipment on the other side of the rail is started to heat that side individually until the specified heating duration, then shut down. The heating equipment operates in a specified working mode, and this process is repeated alternately. This fully utilizes the rail's short-term heat storage capacity to maintain its surface temperature, thus avoiding the drawbacks of excessive power consumption caused by simultaneously starting and stopping heating operations on both sides of the same rail group. This effectively reduces power consumption during snow melting and lowers power usage costs.

[0015] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, and in order to make the above and other objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention are described below.

[0021] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0022] Currently, the common method for controlling heating equipment in existing technologies is to simultaneously start and stop the heating devices installed on all rails within the turnout area, with all operating at full power during startup. However, since turnout areas are mostly located outdoors and the rails themselves are massive, the heating equipment requires extremely high power, resulting in significant energy consumption during snow melting. Specifically, each heating device on both sides of the same rail group within the smallest turnout requires approximately 6 kilowatts, while each heating device on both sides of the same rail group within the largest turnout requires tens of kilowatts. A medium-sized station typically has dozens of turnout areas, while large or super-large stations have over a hundred or even hundreds of turnout areas. This invention selects a heating duration, i.e., the startup duration of the heating equipment, and controls the startup of the heating devices installed on both sides of the target rail group in turn during this duration, executing the heating operation in a specified working mode. This avoids the drawbacks of simultaneously starting and stopping heating on both sides of the same rail group, which leads to excessive energy consumption, effectively reducing energy consumption during snow melting and lowering energy costs.

[0023] Therefore, this invention provides a control method for a turnout heating device, which can reduce the power consumption during the snow melting process and reduce the cost of power usage. The specific execution steps are as follows: Figure 1 As shown, an intelligent power-on / off control module is applied in the turnout snow melting control system. This module controls the heating equipment and includes:

[0024] 101. Determine the heating time corresponding to the target rail group.

[0025] In this embodiment, the target rail group is any rail group located in the turnout area with heating equipment installed on both sides of the rails. It should be noted that in actual tracks, a turnout area typically contains multiple rail groups, meaning multiple turnouts are laid out, and switching between different tracks is achieved through a switch machine, thus ensuring railway transport efficiency. Therefore, in this embodiment, the target rail group is any one of the multiple turnouts within a turnout area. The heating equipment is an electric snow-melting device installed on all rails in the turnout area to melt ice and snow on the rail surface through electrical heating. It is generally installed in groups, meaning heating equipment is installed on both sides of the rails of the same rail group to heat the rail surface. In this embodiment, the executing entity is the intelligent on / off electrical control system in the turnout snow-melting control system. The control module is specifically designed to control the start and stop of the heating equipment. The start and stop of the heating equipment can be controlled through the control program in the intelligent power-on / off control module. Generally, when heating the target rail group, a heating duration is set, which is the start duration of the heating equipment, to ensure that the rail surface temperature of the rails on both sides of the target rail group can be stable to melt the snow on the rail surface. This heating duration can be automatically set by the user according to the actual situation, or a mapping table of environmental changes and heating duration can be preset, so that a corresponding heating duration can be automatically selected from the mapping table based on the environmental changes in the turnout area. This implementation does not limit this.

[0026] 102. Based on the heating time, the heating equipment installed on both sides of the target rail group is controlled in turn to perform heating operations in a specified working mode so as to melt the snow on the rail surface of both sides of the target rail group.

[0027] It should be noted that in this embodiment, since the heating time has been determined in step 101, and this heating time is the start-up time of the heating equipment, and since heating equipment is installed on both sides of the target rail group, and the rail itself has a certain short-term heat storage capacity, that is, the internal heat can be effectively retained in a short time to ensure the melting of snow on the rail surface, in order to reduce the consumption of electrical energy, the heating equipment installed on both sides of the rail can be operated in turn according to the heating time in a specified working mode. That is, first, the heating equipment on one side of the rail is started to heat the rail on that side until the heating time is reached and then turned off, and at the same time, the heating equipment on the other side of the rail is started to heat the rail on that side until the heating time is reached and then turned off, and so on, that is, the heating operation on both sides of the target rail group is performed alternately, making full use of the short-term heat storage capacity of the rail itself. The heating device maintains the rail surface temperature to avoid excessive power consumption caused by simultaneously activating and deactivating heating operations on both sides of the target rail group. The heating device operates in a designated mode upon startup, which can be preset and corresponds to different output powers. Specifically, the operating mode is a power mode, including but not limited to full power, half power, and one-third power modes. The designated operating mode is one of these modes. Therefore, the power output of the heating device is not always full power but is determined by the designated operating mode. This designated operating mode can be manually selected by the user based on actual site conditions or automatically selected and switched based on rail surface temperature changes or environmental data of the turnout area where the target rail group is located. This embodiment does not limit the specific selection. Through this method, the system can simultaneously heat and melt snow on the rail surface while significantly reducing power consumption during the melting process by alternating heating of both sides of the same rail group and during the heating operation. This makes the turnout snow melting system more energy-efficient in the turnout area.

[0028] Based on the above Figure 1As can be seen from the implementation method, the turnout heating equipment control method provided by the present invention first determines the heating duration corresponding to the target rail group when it is necessary to control the turnout heating equipment. The target rail group is any rail group located in the turnout area with heating equipment installed on both sides of the rails. Then, based on the heating duration, the heating equipment installed on both sides of the target rail group is controlled in turn to perform heating operations in a specified working mode so as to melt the snow on the rail surface of both sides of the target rail group. The technical solution provided by this invention allows for the selection of a heating duration, i.e., the start-up duration of the heating equipment. This start-up duration allows for the alternating control of the heating equipment installed on both sides of the target rail group, performing heating operations in a specified working mode. Specifically, the heating equipment on one side of the rail is first started to heat that side individually until the specified heating duration, then shut down. Simultaneously, the heating equipment on the other side of the rail is started to heat that side individually until the specified heating duration, then shut down. The heating equipment operates in a specified working mode, and this process is repeated alternately. This avoids the drawbacks of excessive power consumption caused by simultaneously starting and stopping heating operations on both sides of the same rail group, effectively reducing power consumption during snow melting and lowering power usage costs.

[0029] Furthermore, the preferred embodiment of the present invention is based on the above... Figure 1 Based on this, a detailed explanation of the control process for the turnout heating equipment is provided, including the specific steps as follows: Figure 2 As shown, it includes:

[0030] 201. Determine the heating time corresponding to the target rail group.

[0031] This step combines the description of step 101 in the above method, and the same content will not be repeated here.

[0032] Before this step, it's important to understand that in real-world scenarios, not all turnout areas require snow melting, as this depends on geographical location and climate. For example, southern cities often have less distinct winters, while northern cities have four distinct seasons. Even within northern cities, there are differences; Beijing has shorter winters with less snow, while Harbin has relatively harsher winters with more snow. However, snow melting is not necessary in spring, summer, and autumn. Therefore, to further conserve energy and achieve precise snow melting for rails within the turnout area where there is snow accumulation or a tendency for snow accumulation on the rail surfaces, before this step, it's necessary to determine whether the target rail group meets the pre-set heating rules, i.e., whether snow melting is required. If so, the heating time is determined; otherwise, snow melting is not required, and the heating time does not need to be determined.

[0033] Furthermore, regarding whether the rail assembly in the turnout area is heated before the aforementioned steps to achieve precise snow melting when the rails on both sides of the rail assembly in the turnout area are covered with snow or have a tendency to be covered with snow, thereby further saving power, specifically, it is determined whether the target rail assembly meets the preset heating rules, wherein the preset heating rules are used to characterize the turnout area corresponding to the target rail assembly as having snow melting requirements; if not, the heating equipment installed on both sides of the target rail assembly is controlled to stop performing heating operations; if yes, environmental change data of the turnout area within a specified time is obtained; the heating duration corresponding to the target rail assembly is determined, including: determining the heating duration corresponding to the target rail assembly based on the environmental change data.

[0034] It should be noted that in this step, the preset heating rules include not only the snow cover on the rail surface of the rail group in the turnout area in the image captured by the camera of the track laying, but also the determination of snowfall and low temperature based on weather data obtained from relevant environmental data sensors or the Internet, and the determination that the current period is winter and there has been snowfall based on calendar data obtained from the Internet. All of these can determine that the turnout area corresponding to the target rail group has a need for snow melting. The specific determination method can be based on one of the above, or it can be based on a combination of the above. This embodiment does not limit this. If the determination is negative, it means that the target rail group does not have a snow melting requirement, which does not meet the above-mentioned preset heating rules. In this case, the heating equipment installed on both sides of the target rail group will stop performing the heating operation, i.e., the heating equipment will be turned off. If the determination is positive, the user can customize a heating duration according to the actual situation, or take the environmental change data of the turnout area within a specified time and determine the heating duration corresponding to the target rail group based on the environmental change data. The specified time period can be a week, half a month, a month, etc., which can be customized by the user. This embodiment does not limit this. The environmental change data includes, but is not limited to, temperature changes, weather type changes, wind force level changes, etc.

[0035] 202. Determine the heat storage performance of the rails on both sides of the target rail group.

[0036] The heat storage performance is used to characterize the heat loss rate of the rails on both sides of the target rail group. It should be noted that in this step, since the previous steps mentioned that this embodiment utilizes the short-term heat storage capacity of the rail itself, and many factors affect the heat storage capacity of the rail itself, such as ambient temperature, snow cover, and wind force, these factors, whether directly or indirectly affecting the rail, will influence the heating effect of the heating equipment. Therefore, the heat storage performance of the target rail can be determined by collecting the rail surface temperature of the rails on both sides of the target rail group using a rail temperature sensor installed on the rail for monitoring the rail surface temperature, or by collecting environmental data from environmental sensors installed near the rail. In this embodiment... Without limitation, regarding the heat loss rate, since the heating equipment in this embodiment is controlled by alternating operation of the heating equipment installed on two rails in the same rail group, that is, the start-up time of the heating equipment on one side of the rail is equal to the shut-off time of the heating equipment on the other side of the rail, the heat loss rate of the rail can be indirectly determined by comparing the temperature at the initial and final stages of the shut-off time. In order to ensure the accuracy of the calculation, the average value can be calculated using the data from the initial and final stages of the shut-off time within a certain period, thereby obtaining an accurate heat loss rate and improving the accuracy of determining the thermal storage performance.

[0037] Furthermore, regarding the specific method for determining the heat storage performance of the rails on both sides of the target rail group mentioned in the above steps, the details are as follows:

[0038] Scenario 1:

[0039] While most turnout areas are located outdoors, some are situated within tunnels or covered stations. This means that although trains passing through these areas may carry snow that falls onto the rails of the target rail assembly, determining the performance based solely on environmental data is not always applicable. For example, wind speeds in tunnels are generally higher than outdoors. Therefore, a more accurate approach is to determine the performance based on the rail surface temperature changes. This involves using only rail surface temperature data collected by rail temperature sensors installed on the rails, ensuring the accuracy of the rail heat storage performance assessment. Specifically, the rail surface temperatures of the two rails in the target rail assembly are collected; these temperatures are then compared to the upper and lower limits of a preset snow melting temperature range to obtain the corresponding comparison results; and finally, the heat storage performance of the two rails in the target rail assembly is determined based on these comparison results. It should be noted that in this step, the preset snow melting temperature range is the temperature range that can maintain the temperature of the snow on the rail surface to melt, such as 5-15 degrees, 10-20 degrees, etc. Users can customize the setting according to the actual local conditions, or determine it according to the historical data of local snow melting. This embodiment does not limit this. By comparing the rail surface temperature with the upper and lower limits of the preset snow melting temperature range, the change of the rail surface temperature can be known, and the heat loss rate of the rail can be determined, thereby determining the heat storage performance of the rail.

[0040] Scenario 2:

[0041] Since turnout areas are mostly located outdoors, in addition to using track temperature sensors installed on the rails, environmental data collected by environmental sensors installed near the rails can also be used to determine the heat storage performance of the rails. This can be used as a disaster recovery plan for scenario one, or as an auxiliary plan for scenario one. This embodiment does not limit this; either method can be selected according to user-defined settings. Specifically, environmental data corresponding to the turnout area is collected; the environmental level corresponding to the turnout area is determined based on the environmental data. The environmental level is used to characterize the degree of influence of the turnout area on the heat loss rate of the rails on both sides of the target rail group under different environmental conditions. The heat storage performance of the rails on both sides of the target rail group is determined based on the environmental level. It should be noted that in this step, the environmental data includes at least one of wind force level, ambient temperature, weather type, and snowfall. Specifically, multiple thresholds or conditions corresponding to wind force level, ambient temperature, weather type, and snowfall can be preset, and dynamic weights can be set for each threshold level or each condition. These dynamic weights can be set according to the degree of influence of wind force level, ambient temperature, weather type, and snowfall on the heat loss rate, thereby determining the environmental level corresponding to the turnout area based on weight calculation. Alternatively, single thresholds can be set for wind force level, ambient temperature, weather type, and snowfall, and the environmental level corresponding to the turnout area can be determined based on the number of items exceeding the single threshold. This embodiment does not limit this. For example, when the ambient temperature decreases, the wind force level is high, and the weather type is snowfall, the performance level of the rail's heat storage performance can be considered as low or level one. However, it should still be emphasized that the performance level of heat storage performance corresponds to different power operating modes of the heating equipment.

[0042] 203. Determine the specified operating mode of the heating equipment installed on the two sides of the target rail group by utilizing the heat storage performance of the rails on both sides of the target rail group.

[0043] It should be noted that in this step, the specified operating mode is a heating device operating mode that outputs a specified power, either selected by the user based on actual conditions or automatically determined based on the thermal storage performance. The preset operating modes of the heating device include full power mode, half power mode, and one-third power mode. That is, the specified operating mode is one of the preset operating modes. Therefore, the process of determining the specified operating mode specifically involves: pre-classifying the performance levels corresponding to the thermal storage performance; establishing the correspondence between performance levels and preset operating modes; using the correspondence to determine the target preset operating mode corresponding to the heating device installed on both sides of the target rail group, and using the target preset operating mode as the specified operating mode. It should be noted that since this embodiment defines three preset working modes, the corresponding performance levels of the rail's heat storage performance are three levels: low, medium, and high, or level one, level two, and level three. There is a corresponding relationship between the two. The lower the performance level, the higher the power of the corresponding preset working mode. For example, a low performance level indicates a high heat loss rate from the rail, meaning a large temperature gradient on the rail surface. In this case, the heating equipment needs to operate at full power. Conversely, a high performance level requires a one-third or half-power mode. In this embodiment, half-power mode is generally used. This method allows for rapid determination of the corresponding specified working mode based on the heat storage performance, facilitating subsequent heating operations based on that mode and effectively improving the efficiency and accuracy of determining the preset working mode of the heating equipment.

[0044] 204. Based on the heating duration, the heating equipment installed on both sides of the target rail group is controlled in turn to perform heating operations in a specified working mode so as to melt the snow on the rail surface of both sides of the target rail group.

[0045] This step combines the description of step 102 in the above method, and the same content will not be repeated here.
