Description

Technical Field

[0001] The present invention relates to the technical field of regional layout, and in particular to a method and system for dynamically adjusting the layout of a reservoir area. Background Art

[0002] With the development of the logistics industry, the safety management of warehouses has become increasingly important. As the core area for cargo storage, loading and unloading, and transportation, warehouses are prone to accidents if they are not properly managed. Traditional management methods often lack clear guidance, resulting in the cross-operation of personnel, machinery, and transportation tools, increasing safety risks.

[0003] The existing warehouse area plans the scope and function of the area by marking lines, clearly demarcates the walking passages for personnel and the driving paths for vehicles, and avoids cross-operation areas. The existing warehouse area is often marked by staff passing by the warehouse area. According to the actual warehouse process, the scope of the approximate application area in the warehouse area is roughly estimated, and the lines are drawn manually. However, this line drawing method often cannot dynamically adjust the warehouse layout according to the working status of the warehouse area, resulting in insufficient operating efficiency and safety. Summary of the invention

[0058] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0059] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.

[0060] The embodiment of the present invention provides a method for dynamically adjusting the layout of a storage area. Figure 1 , Figure 1 A flowchart of a method for dynamically adjusting the layout of a storage area provided by an embodiment of the present invention. The method comprises the following steps:

[0061] Get the movable area in the warehouse area and draw lines on the edges of the movable area; place two carts at two symmetrical edge lines of the movable area respectively;

[0062] Send movement instructions to the two carts, and the two carts move along the two symmetrical edge lines of the movable area according to the movement instructions to the preset position, and use the connecting straight line between the two carts as the initial connecting straight line; the area closed by the initial connecting straight line and the edge line of the movable area that is not followed when not moving is recorded as the initial activity area;

[0064] The area under-size coefficient is compared with a preset area under-size coefficient threshold. When the area under-size coefficient is not less than the preset area under-size coefficient threshold, a new activity area is obtained according to the area under-size coefficient and the area of ​​the initial activity area.

[0065] According to the new area of ​​the activity area, the two trolleys are driven to move along the two symmetrical edge lines of the movable area, so as to adjust the area of ​​the activity area of ​​the warehouse.

[0066] Based on a method for dynamically adjusting the warehouse area layout provided by an embodiment of the present invention, the warehouse area layout can be dynamically adjusted according to the working status of the warehouse area through the above method, thereby improving the working efficiency of the warehouse area and improving safety assurance.

[0067] It should be noted that if Figure 2 The moving principle diagram of a method for dynamically adjusting the layout of a storage area is shown in FIG. Figure 4 The two trolleys shown are placed at two symmetrical edges of the movable area respectively. The two trolleys move along the edge lines of the movable area to determine the initial activity area. In this way, there is no need to draw lines manually, which can effectively avoid the errors and inaccuracies that may be caused by manual drawing of lines. In addition, for obtaining the movable area and drawing lines: first, all movable areas in the storage area are obtained through sensors or other monitoring equipment; then, lines such as Figure 2 The lines shown in the figure are used to make it clear which parts are the areas where the trolleys can move; the trolley positioning and the setting of the initial connection line: the two trolleys are positioned at the two symmetrical edges of the movable area, ensuring that they are located at both ends of the area. Then, movement instructions are issued to the trolleys to guide them to move along the two symmetrical edges until they reach the preset positions. The straight line connecting the two trolleys will serve as the initial connection line, which can be used to define the initial activity area. Define the initial activity area: The initial activity area is determined by the closed area formed by the initial connection line and the edge of the movable area that is not along the edge; this activity area is the initial working area and may not fully meet the actual operation requirements. It needs to be adjusted according to the actual operation situation.

[0068] It should be noted that this step of defining the initial activity area is of great significance, as it provides a basis for subsequent dynamic adjustments. Through the closed area formed by the initial connecting straight line and the edge of the movable area, a preliminary activity area can be clearly determined. This area is delineated based on the actual situation of the current warehouse layout and the positioning of the trolley. Although this area may not be perfect at the beginning and there may be some wasted space or underutilized areas, it provides a clear reference framework for subsequent activity data collection and adjustments. The benefit of this step is that it not only provides a starting point for subsequent dynamic adjustments, but also lays the foundation for real-time monitoring and data collection, helping the system to more accurately calculate which areas need to be expanded or reduced, thereby ensuring that the final activity area can better adapt to actual operational needs, improve operational efficiency, reduce resource waste, and effectively guarantee safety.

[0069] In one embodiment, activity data in the initial activity area within a preset time period is obtained, and the area under-size coefficient is calculated based on the activity data; the activity data includes an excess activity area coefficient, an activity density coefficient, and an activity congestion coefficient;

[0070] Among them, the excess activity area coefficient includes:

[0071] Obtain the number of activities that exceed the initial activity area within a preset time period, obtain the excess area each time the activity exceeds the initial activity area, and sequence the excess areas each time the activity exceeds the initial activity area based on the time sequence to obtain an excess area sequence;

[0072] Calculate the mean of the excess area series as the excess area deviation value;

[0073] Calculate the standard deviation of the excess area series as the excess area fluctuation value;

[0074] The excess activity area coefficient is calculated based on the number of activities beyond the initial activity area, the excess area deviation value, and the excess area fluctuation value. The calculation formula is: Dsx=a1×cf+a2×cn+a3×cv; where Dsx is the excess activity area coefficient, cf, cn, and cv are respectively the number of activities beyond the initial activity area, the excess area deviation value, and the excess area fluctuation value; a1, a2, and a3 are respectively the preset weight coefficients of the number of activities beyond the initial activity area, the excess area deviation value, and the excess area fluctuation value.

[0075] It should be noted that a1, a2 and a3 are set by professionals according to actual conditions. Generally, the sum of a1, a2 and a3 is 1. For example, a1, a2 and a3 can be 0.3, 0.3 and 0.4 respectively. They can also be other numbers without specific limitation.

[0076] It should be noted that the real-time location of the vehicle, person or equipment is tracked through ground sensors or RFID tags to determine whether there is any activity beyond the preset activity area. Each time an activity exceeds the preset activity area, the system will record the area exceeded, which can be obtained by comparing the sensor positioning with the area boundary. The number of exceeding activities is automatically counted by the system, and the number of times each exceeding activity occurs is recorded.

[0077] It should be noted that the larger the coefficient of the excess activity area, the larger the coefficient of the area of ​​the initial activity area is too small, and the more the area of ​​the activity area needs to be increased. The reason is that the larger the coefficient of the excess activity area, the higher the deviation and volatility of the number of times the activity area is exceeded and the area is exceeded within the preset initial activity area, which directly reflects that the space of the activity area cannot meet the current operation needs. Specifically, the increase in the number of excess times indicates that the activity density in the area is high, and personnel or equipment frequently enter the excess area, which may cause congestion in the area, obstruction of operations or reduced efficiency. Large deviations and fluctuations in the excess area indicate that the spatial planning of the activity area is unstable, and some areas may be too crowded while other areas are idle, thus affecting the overall workflow and safety. Based on these situations, when the coefficient of the excess activity area is large, it means that the current area is too small to effectively accommodate all activities. Therefore, it is necessary to increase the area of ​​the activity area to disperse the pressure of operations, reduce congestion, improve work efficiency, and ensure the smooth progress of safe operations.

[0078] In one implementation method, the benefits of analyzing the excess activity area coefficient for determining whether the area of ​​the activity area needs to be increased are as follows: it can quantitatively reflect whether there is a problem of insufficient space in the current activity area. By monitoring the number of excess activities and area deviations, it can accurately determine which areas have too tight space and where there may be a waste of resources; the excess activity area coefficient takes into account the volatility and instability of activities, which helps managers identify areas with large dynamic changes, so as to adjust the layout more flexibly; through this data-driven approach, the area of ​​the activity area can be adjusted in real time and dynamically, avoiding the lag of traditional empirical adjustments, ensuring the efficiency, safety and optimal use of resources in warehousing operations, thereby reducing accident risks and operational bottlenecks.

[0079] In one embodiment, the activity density coefficient includes:

[0080] The initial activity area is divided into several sub-areas, and the activity frequency and activity duration of each sub-area are recorded, and the activity frequency and activity duration of each sub-area are marked as F i and T i , i represents the ordinal number of the number of sub-regions, and i∈[1,n], and n is a positive integer;

[0081] For each sub-area, the corresponding activity density is calculated using the following formula: In the formula, C i is the activity density of the ith sub-region, S i is the area of ​​the ith sub-region;

[0082] Calculate the mean activity density of all sub-areas to obtain the activity density coefficient. The calculation formula is: Where TU is the activity density coefficient.

[0083] It should be noted that in each sub-area, the activity frequency (i.e., the number of times an activity occurs in the area) and activity duration (i.e., the duration of the activity) of people or equipment in the area are recorded through sensors, cameras, RFID or other monitoring equipment. These data will be counted according to time periods to ensure that they can reflect the activities in the sub-area; in addition, the division of sub-areas is set by professionals based on actual conditions, and no specific restrictions or elaborations are made.

[0084] It should be noted that the larger the activity density coefficient, the smaller the area of ​​the initial activity area. The larger the coefficient, the more it is necessary to increase the area of ​​the activity area. The reason is that the larger the activity density coefficient, the higher the frequency and duration of activities per unit area, reflecting the high intensity of use of the area. If the activity density coefficient is too large, it usually means that the space in the area cannot effectively carry the current amount of activities, resulting in frequent and concentrated activities of operators, equipment or goods, increasing the risk of resource conflicts and congestion. At this time, the original area may not be enough to meet the actual operation needs, thereby affecting work efficiency and safety. Therefore, when the activity density coefficient is high, it indicates that the space in the initial activity area is insufficient, and it is urgent to expand the area to disperse activities, improve resource utilization, avoid efficiency decline and safety hazards caused by space limitations, and ensure the smoothness and safety of the working environment.

[0085] In one implementation, the benefits of analyzing the activity density coefficient for determining whether the area of ​​the activity area needs to be increased are: by calculating the activity density of each sub-area, the use intensity and resource allocation of the area can be objectively reflected; if the activity density coefficient is high, it means that the spatial carrying capacity of the area is close to the limit, and there may be problems such as equipment or personnel congestion and reduced operating efficiency. At this time, with the help of the activity density coefficient, managers can promptly identify overly concentrated areas, and then take measures to increase the area of ​​the area or optimize the spatial layout to avoid safety hazards and waste of resources caused by insufficient space; the activity density coefficient can not only provide data support for regional expansion, but also help achieve more reasonable spatial planning, thereby improving overall operating efficiency and safety.

[0086] In one embodiment, the activity congestion coefficient includes:

[0087] The actual number of activity units in the initial activity area is compared with the preset maximum number of units that can be accommodated in the area, and the activity congestion coefficient between the actual number of activity units and the maximum number of units that can be accommodated in the area is calculated;

[0088] The area under-dimension coefficient is calculated based on the excess activity area coefficient, activity coefficient, and activity congestion coefficient. The calculation formula is:

[0089]

[0090] Where EFG is the area under-diminished coefficient, Dsx, TU and RF are the excess activity area coefficient, activity coefficient and activity congestion coefficient respectively, α, β and γ are the preset proportional coefficients of Dsx, TU and RF respectively, and α, β and γ are all greater than 0.

[0091] It should be noted that α, β, and γ are set by professionals according to actual conditions. Generally, the sum of α, β, and γ is 1. For example, α, β, and γ can be 0.2, 0.4, and 0.4 respectively. They can also be other numbers without specific limitation.

[0092] It should be noted that the actual number of active units refers to the number of personnel, equipment or other work units that actually enter and perform tasks in the initial activity area within a preset time period. These data can be tracked and counted through real-time monitoring systems (such as RFID, cameras, sensors, etc.), recording the actual number of active units entering the area in each time period. The preset maximum number of units that can be accommodated is the ideal capacity calculated based on the spatial capacity of the area, operational requirements, and the maximum carrying capacity of equipment and personnel. This can be estimated based on the area, operating procedures, spatial layout and safety standards, and is usually provided by the warehouse planning or management system. By comparing the actual number of active units with the maximum number that can be accommodated, the activity congestion coefficient can be effectively calculated to determine whether the area is overcrowded.

[0093] In one embodiment, the calculation formula for obtaining the new active area area according to the area undersize coefficient and the area of ​​the initial active area is:

[0094] GH=GT×(1+EFG)

[0095] Where GH is the area of ​​the new active region, GT is the area of ​​the initial active region, and EFG is the area undersize coefficient.

[0096] It should be noted that the preset area under-size coefficient threshold is set by professionals based on actual conditions and is not limited or elaborated on in detail.

[0097] It should be noted that when the area under-size coefficient is not less than the preset area under-size coefficient threshold, it means that the area of ​​the current activity area is not enough to meet the operation needs, the space becomes crowded, and cannot effectively accommodate the required operators, equipment or goods. This may lead to reduced operation efficiency, uneven resource allocation, and increased safety risks. Too compact space will cause cross-operation between equipment and personnel, increase the possibility of collisions and accidents, and the workflow may be hindered. Therefore, when the area under-size coefficient is not less than the threshold, it means that the activity area needs to be expanded to ensure that the operation can proceed smoothly, improve work efficiency, and reduce safety hazards.

[0098] When the area undersize coefficient is less than the preset area undersize coefficient threshold, it means that the area of ​​the current activity area is sufficient to support the operation needs, the space is used reasonably, and the operators and equipment can work smoothly. The operation efficiency is high, the flow of personnel and equipment operation are not hindered, and the operation process is stable and safe. At this time, the area of ​​the area can meet the needs of the current operation, and the resource allocation is relatively balanced. There is no need to expand the area of ​​the activity area. The existing area can provide enough space to complete the scheduled tasks.

[0099] In one implementation method, according to the new area requirements, the two carts are adjusted to move outward along the two symmetrical edges of the movable area. This movement process requires precise control of the driving route and speed of the carts to ensure that the two carts move in parallel along the preset path at the edge of the movable area and stop at the appropriate time until the area of ​​the active area reaches the new target value. During the adjustment process, the two carts travel along the two symmetrical edges, and their moving distances are monitored in real time to ensure that the area of ​​the expanded area does not exceed the limit of the movable area. Whenever the cart completes a certain amount of movement, the actual area data of the active area can be fed back through the sensor or positioning system and compared with the target area. If it is found that the area of ​​the active area has reached or is close to the preset target value, the movement of the cart can be stopped to ensure that the area of ​​the newly adjusted area meets the operation requirements. Throughout the process, the path planning, speed control and real-time feedback mechanism of the cart are key to ensure that the area expansion is smooth and efficient. Through such dynamic adjustment, not only can the size of the active area of ​​the warehouse area be flexibly changed according to actual needs, but also the smooth operation of each link in the operation process can be ensured, avoiding the decline in efficiency and safety hazards caused by insufficient space, thereby optimizing the operation process of the warehouse area and improving the overall operation efficiency.
