[0052] The lighting control method, apparatus, equipment, storage medium, and yard bridge provided in this application embodiment can deploy lighting equipment at the bottom of the trolley, thereby saving lighting equipment while expanding the lighting area. When determining the lighting brightness, the height difference between the spreader and the trolley in the yard bridge can be determined based on the position of the spreader in the yard bridge, and the initial lighting brightness of the lighting equipment can be determined based on this height difference. At this point, coarse adjustment of the lighting brightness can be achieved based on the spreader height, which not only improves the response speed of the yard bridge supplementary lighting system but also reduces the full-power operation time of the light source, reduces ineffective energy consumption, and provides a reference value for subsequent fine adjustment. Then, the actual brightness value of the working area under the spreader at the initial lighting brightness can be determined. If the lighting brightness of the working area meets the brightness adjustment requirements based on the actual brightness value, a matching compensation brightness value is determined. Fine adjustment of the lighting equipment can then be achieved through the compensation brightness value, realizing control of the lighting brightness based on the initial lighting brightness and the compensation brightness value. At this point, by compensating for the brightness value, the lighting brightness of the work area can be adjusted in real time, ensuring that the lighting brightness in the work area always meets the lighting requirements, thereby improving the lighting stability of the yard bridge's lighting equipment.

[0058] Figure 5 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application.

[0059] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0060] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0061] The yard crane is the core equipment used for lifting containers in port terminals. At night or in environments with insufficient light, supplemental lighting equipment is usually needed to illuminate the work area to ensure the precise operation of the spreader.

[0062] In one implementation, supplemental lighting equipment (i.e., illumination equipment) may be deployed on the main beam of the bridge. In this case, because the main optical axis of the lighting equipment (e.g., lamps) is vertically downward and the position of the lighting equipment is fixed, it is necessary to add a set of lamps at intervals along the main beam to ensure that the lighting in the entire working area under the bridge meets the operational requirements. This implementation requires deploying a large number of lighting devices on the main beam of the bridge (e.g., deploying 6 to 8 sets of lighting equipment), resulting in high lighting power consumption during nighttime operations and a certain degree of resource waste.

[0063] In another implementation, lights can be mounted on the hoisting device, thereby reducing the consumption of lighting equipment. However, this implementation can only provide supplemental lighting below the hoisting device, not the hoisting device itself. This means that additional supplemental lighting is required when switching to manual operation, which not only limits the application scenarios of the supplemental lighting system but also affects work efficiency. Furthermore, if the hoisting device operates at a high speed, the adjustment value of the lighting equipment may be too large, affecting the real-time performance of the lighting brightness adjustment and causing a certain degree of lag in the lighting equipment.

[0064] Furthermore, in related technologies, lighting equipment is usually in a fully on or fixed power state, which means that the brightness of the lighting equipment cannot be adjusted in real time, resulting in energy waste.

[0065] The lighting control method for a yard crane provided in this application reduces the amount of lighting equipment required and thus lowers power consumption by deploying lighting equipment at the bottom of the crane's trolley. Simultaneously, it enables full-area lighting above and below the spreader, meeting the supplementary lighting / illumination needs of various work scenarios. In practice, the initial illumination brightness of the lighting equipment can be determined based on the spreader height, achieving coarse adjustment. Then, a compensation brightness value is determined based on the actual brightness value of the work area to achieve fine adjustment. This combined coarse and fine-grained lighting control method improves the response speed and control accuracy of the yard crane's lighting system, further saving energy and avoiding waste.

[0066] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0067] Figure 1 This is a flowchart illustrating a lighting control method for a track bridge according to an embodiment of this application. The method is applied to a track bridge, and at least one set of lighting devices is deployed on the bottom of the track bridge trolley.

[0068] Optionally, in this embodiment, a set of lighting equipment can be deployed in the central area of ​​the bottom of the trolley of the yard bridge, or a set of lighting equipment can be deployed on both sides of the trolley (e.g., the front and rear or left and right sides of the work area), or a set of lighting equipment can be deployed at each corner of the bottom of the trolley of the yard bridge, or a set of lighting equipment can be deployed on each side of the bottom of the trolley of the yard bridge (e.g., the midpoint of each side), etc. There is no limitation on the type of lighting equipment used or the number of lighting equipment deployed, as long as the lighting equipment can completely cover the work area.

[0069] Based on this, such as Figure 1 As shown, the lighting control method for the yard bridge provided in this application includes:

[0070] S101. Determine the height difference between the spreader and the trolley in the yard bridge based on the location of the spreader in the yard bridge.

[0071] Optionally, in this embodiment of the application, the location of the spreader in the yard bridge can be determined based on the radar point cloud data collected by the radar sensor, and the height difference between the spreader and the trolley can be determined based on the location of the spreader.

[0072] S102. Based on the height difference, determine the initial lighting brightness of the lighting equipment and the actual brightness value of the working area under the hoist under the initial lighting brightness.

[0073] Optionally, in this embodiment of the application, a real-time image including the lifting device can be obtained from a camera sensor, and the working area under the lifting device can be determined based on the location of the lifting device.

[0074] Optionally, the working area under the spreader can be determined by performing target recognition processing on the real-time video and based on the identified container operating under the spreader.

[0075] Optionally, the working area under the spreader can be determined based on a preset working range. For example, the preset working range can be a rectangular area with a length of B and a width of C, centered at a point A below the spreader. The preset working range is not limited here; it should be determined according to the actual needs of the working scenario.

[0076] S103. If the actual brightness value determines that the lighting brightness of the work area meets the brightness adjustment requirements, then determine the matching compensation brightness value.

[0077] Optionally, brightness adjustment requirements are used to determine whether the actual brightness value meets the lighting needs of the work area.

[0078] Optionally, embodiments of this application can determine whether the lighting brightness of the work area meets the brightness adjustment requirements by comparing the actual brightness value with the ideal brightness value (i.e., the ideal lighting brightness).

[0079] Optionally, when comparing the actual brightness value with the ideal brightness value, the comparison can be achieved by calculating the difference between the actual brightness value and the ideal brightness value, or by calculating the ratio between the actual brightness value and the ideal brightness value. There is no limitation on this, and the comparison should be based on what can be achieved.

[0080] S104. Control the lighting brightness of the lighting equipment based on the initial lighting brightness and the compensation brightness value.

[0081] Optionally, the lighting brightness of the lighting equipment can be determined based on the sum of the initial lighting brightness and the compensation brightness value. In practice, the lighting brightness of the lighting equipment can be adjusted first based on the initial lighting brightness, and then further adjusted based on the compensation brightness value, thereby achieving control over the lighting brightness of the lighting equipment.

[0082] As described above, this embodiment of the application allows lighting equipment to be deployed in a trolley, thereby saving on lighting equipment while expanding the lighting area. When determining the lighting brightness, the height difference between the spreader and the trolley in the yard crane can be determined based on the spreader's location, and the initial lighting brightness is then determined based on this height difference. This allows for coarse adjustment of the lighting brightness based on the spreader height, improving the response speed of the yard crane's supplemental lighting system, reducing the full-power operation time of the light source, lowering ineffective energy consumption, and providing a reference value for subsequent fine-tuning. Next, the actual brightness value of the work area under the spreader at the initial lighting brightness can be determined. If the actual brightness value indicates that the lighting brightness of the work area meets the brightness adjustment requirements, a matching compensation brightness value is determined. Fine-tuning of the lighting equipment can then be achieved using the compensation brightness value, allowing control of the lighting brightness based on the initial and compensation brightness values. This enables real-time adjustment of the lighting brightness in the work area through the compensation brightness value, ensuring that the lighting brightness in the work area always meets the lighting requirements, thereby improving the lighting stability of the yard crane's lighting equipment.

[0083] Figure 2 A schematic flowchart of another lighting control method for a field bridge provided in this application embodiment is shown below. Figure 2 As shown, in this embodiment... Figure 1 Based on the embodiments, the lighting control method for the yard bridge is described in detail, and the method includes:

[0084] S201. Determine the height difference between the spreader and the trolley in the yard bridge based on the location of the spreader in the yard bridge.

[0085] In one example, this step can be referred to the content described in S101 above, and will not be repeated in detail here.

[0086] S202. Determine the initial lighting brightness of the lighting equipment based on the height difference and the preset brightness distance model.

[0087] Optionally, the preset brightness distance model can be any height-brightness correlation model. For example, the preset brightness distance model can be a machine learning model or an optical model. The type of preset brightness distance model is not limited here, as long as it is feasible. For example, the preset brightness distance model can be an inverse square law model of illumination.

[0088] This implementation method can quickly and easily determine the initial illumination brightness of the lighting equipment based on the height difference, thereby improving the response speed of the supplementary lighting system.

[0089] Optionally, if the preset brightness distance model is a machine learning model, the initial lighting brightness that matches the height difference can also be determined comprehensively based on the ambient light intensity, the attitude of the hoist, and the position of the light source. Here, the specific implementation method of determining the initial lighting brightness of the lighting equipment based on the height difference and the preset brightness distance model is not limited.

[0090] S203. Determine the actual brightness value of the working area under the lifting device under the initial lighting brightness.

[0091] Optionally, after determining the working area under the spreader, the average brightness of the working area can be determined and set as the actual brightness value.

[0092] Optionally, after determining the actual brightness value under the initial lighting brightness, the difference between the actual brightness value and the ideal brightness value can be judged, and the brightness adjustment requirements can be determined based on this difference. In this case, if the difference between the actual brightness value and the ideal brightness value is used to determine whether the lighting brightness of the work area meets the brightness adjustment requirements, please refer to the process described below.

[0093] S204. Determine the luminance difference between the actual luminance value and the ideal lighting luminance.

[0094] If the brightness difference is less than the difference threshold, it is determined that the lighting brightness of the work area does not meet the brightness adjustment requirements. In this case, it is not necessary to adjust the initial lighting brightness.

[0095] S205. If the brightness difference is greater than or equal to the difference threshold, then the lighting brightness of the work area is determined to meet the brightness adjustment requirements.

[0096] At this point, you can adjust the brightness according to the process described below.

[0097] In one possible implementation, embodiments of this application can ensure the stability of the lighting control of the field bridge by determining a dynamic difference threshold, thereby avoiding frequent adjustments to the brightness of the lighting equipment due to short-term brightness fluctuations.

[0098] Optionally, a dynamic difference threshold can be determined through the following process.

[0099] First, obtain historical brightness data for the work area.

[0100] Then, the difference threshold is determined based on the rate of change of historical brightness data.

[0101] Optionally, if the rate of change of historical brightness data is greater than the rate of change threshold, it indicates that the brightness of the work area has changed drastically. In this case, the brightness of the lighting equipment can be avoided by increasing the difference threshold.

[0102] S206. If the actual brightness value determines that the lighting brightness of the work area meets the brightness adjustment requirements, then determine the matching compensation brightness value.

[0103] In one possible implementation, when determining the matching compensation brightness value, the compensation brightness value of the lighting device can be determined based on a preset brightness adjustment model, the actual brightness value, the location of the lighting device, and the brightness difference between the actual brightness value and the ideal lighting brightness.

[0104] Optionally, a preset brightness adjustment model can be used to instruct the neural network model.

[0105] This implementation method can determine accurate and reliable compensation brightness values ​​through a preset brightness adjustment model, thereby improving the lighting control accuracy of the track bridge.

[0106] In one possible implementation, multiple sets of lighting equipment can be deployed at the bottom of the trolley of the yard crane, and the shape of the work area can be regular or irregular (e.g., the shape of the work area in a container tilting scenario).

[0107] Based on this, in order to further improve the lighting control accuracy of the yard bridge and reduce power consumption, the embodiments of this application can determine the compensation brightness value of the lighting equipment according to the actual lighting needs of the work area.

[0108] Optionally, the actual lighting requirements of the work area can be determined based on the shape of the work area, as described in the process below.

[0109] First, determine the shape of the work area.

[0110] Then, based on the shape of the task, the lighting weight of each lighting device is determined.

[0111] Optionally, the lighting weight can be 1, a value greater than 1, or a value less than 1, thereby enabling flexible adjustment of the compensation brightness value.

[0112] For example, if the work area has a regular shape, then the lighting weight of each lighting device can be determined to be 1.

[0113] For example, if the work area has an irregular shape, the lighting weight of the corresponding lighting equipment can be increased or decreased. For instance, if the work area has the shape of a container tilting scenario, the lighting weight of the lighting equipment on the longer side of the work area can be increased (e.g., 1.1), and the lighting weight of the lighting equipment on the shorter side of the work area can be decreased (e.g., 0.9).

[0114] Finally, based on the lighting weight, the compensation brightness value of each lighting device is adjusted to obtain the adjusted compensation brightness value.

[0115] S207. Control the lighting brightness of the lighting equipment based on the initial lighting brightness and the compensation brightness value.

[0116] As can be seen from the above description, the embodiments of this application can achieve preliminary control of the lighting of the yard bridge by the height of the spreader, and perform fine control of the lighting according to the actual situation of the work area. This not only improves the accuracy and stability of the lighting control of the yard bridge, but also saves energy and reduces power consumption.

[0117] Figure 3 This is a schematic diagram illustrating the implementation process of a lighting control method for a field bridge provided in an embodiment of this application, as shown below. Figure 3 As shown, the process includes:

[0118] 1. Based on the radar sensors deployed on the bottom of the trolley of the yard bridge, determine the location of the spreader and the height difference between the spreader and the trolley of the yard bridge;

[0119] 2. Determine the initial lighting brightness of the lighting equipment based on the height difference and the preset brightness distance model;

[0120] 3. Based on the real-time images obtained from the camera sensors, and based on the position of the spreader in the real-time images, determine the working area under the spreader;

[0121] 4. Determine the actual luminance value of the work area under the initial lighting luminance;

[0122] 5. Determine the brightness difference between the actual brightness value and the ideal lighting brightness value. If the brightness difference is greater than or equal to the difference threshold, skip to step 6; otherwise, determine that the compensation brightness value of the lighting equipment is 0 and proceed to step 7.

[0123] 6. Based on the preset brightness adjustment model, and taking into account the actual brightness value, the location of the lighting equipment, and the brightness difference, determine the compensation brightness value of the lighting equipment;

[0124] 7. Control the lighting brightness of the lighting equipment based on the actual brightness value and the compensated brightness value.

[0125] 8. Repeat the process described in 1-7 until the end to ensure that the lighting brightness of the work area meets the real-time work requirements.

[0130] Control unit 404 is used to control the lighting brightness of the lighting equipment based on the initial lighting brightness and the compensation brightness value.

[0131] In one possible implementation, the first determining unit 402 is configured to:
