Description

Technical Field

[0001] The present invention relates to the technical field of warehouse management, and in particular to a warehouse management system based on big data communication. Background Art

[0002] The warehouse management system is based on the standardization of warehouse construction and the standardization of operation management. It is carried out based on the actual situation of existing warehouses through renovation, upgrading or new construction, and introduces high-tech intelligent equipment to achieve refined management of the entire process of materials under warehouse management.

[0003] In certain areas or seasons, the rainy season is frequent and the air humidity is high. Building materials can easily become damp to varying degrees, resulting in reduced strength and affecting the use of building materials. In particular, some construction materials that are susceptible to moisture can be easily damaged or require drying. In existing technologies, real-time monitoring and allocation systems for building materials can effectively control the transportation and use of building materials. However, in highly humid environments, the speed at which building materials become damp will be greatly accelerated, and building material transportation points cannot obtain the moisture conditions of building materials stored in storage warehouses in real time and accurately. At the same time, containers for loading building materials are provided with openings on the top for taking materials, but this results in differences in the time and humidity of water vapor invading building materials at different locations in the loading container. Therefore, it is very necessary to design a warehouse management system based on big data communication with high detection accuracy and strong transportation control and adjustment capabilities.

The distances from the warehouse door are R1, R2...RV , where V is the number of rows of building material containers from one door opening side to the other side in the overhead view of the warehouse.

[0017] According to the above technical solution, in step S2, a sampling instrument is set up in the warehouse at a distance of L meters from the warehouse door, and M kilograms of building materials are spread flat in the sampling instrument. The sampling module divides the sampling instrument into two layers according to the mass of the building materials. The upper layer of the sampling instrument is in contact with the air. The height of the upper and lower layers is h. The building materials in the sampling instrument gradually absorb water vapor. When the mass of the upper layer exceeds Q1 kilograms, the moisture ratio of the upper layer is The amount of water vapor absorbed by the upper building materials will affect the building effect. At this time, the quality of the lower layer is Q2. At this time, the moisture ratio of the lower layer is The time displayed by the timing unit is S1; when the mass of the upper layer exceeds P1 kg, the moisture ratio of the upper layer is It is determined that the amount of water vapor absorbed by the upper building materials seriously affects the building effect, and the time displayed by the timing unit is S2.

[0018] According to the above technical solution, step S3 further includes:

[0019] Step S31: The building materials transported in batches are packed in containers. The height of the packing container is H. The container is divided into The height of each layer is h.

[0023] Step S33: When the degree F1 of the outside temperature drop within 1 hour is higher than 50% of the maximum temperature difference F of the day, the system determines that the speed of water vapor infecting the building materials has changed significantly. Within B hours before the outside temperature returns to 50% of the current temperature change, the speed of water vapor infecting the building materials is calculated as the current speed of water vapor infecting the building materials. times, the time when the Kth layer of building materials reaches the safe moisture level line At the same time, the time when the building materials of the Kth floor reach the dangerous moisture level line is

After the building materials are transported in batches and stored in containers, of the building materials will be After 15 days, it reaches the safe moisture level line; of the building materials will be After a few days, the dangerous moisture level was reached;

[0026] Step S42: When the ratio of the dryness of the building materials in the container to the safe moisture level line is higher than 70%, it is determined that the dryness of the current container is good and other building materials are used first;

[0027] Step S43: When the ratio of the dryness of the building materials in the container to the safe moisture level line is lower than 70%, it is determined that the current container is damp, and the building materials are used first;

[0028] When the ratio of building materials in the container between the safe moisture level line and the dangerous moisture level line is higher than 50% and the ratio of building materials at the dangerous moisture level line exceeds 0.8A%, the communication module will prompt the staff at the shipping place to reduce the transportation volume of building materials and increase the transportation frequency of building materials while ensuring that the total transportation volume of building materials remains unchanged.

[0033] See also Figure 1 The present invention provides a technical solution: a warehouse management system based on big data communication, comprising:

[0035] The present invention uses a stacking control module to accurately monitor the time it takes for building materials to become damp under the influence of real-time temperature changes, and visualizes the differences in humidity among building materials stored at different locations in the warehouse and at different heights in loading containers, effectively reducing the safety risk of humidity affecting the quality of building materials during their stacking. At the same time, real-time reporting through the communication module ensures the safe and stable operation of the construction site, ensures that the usage and storage volume of building materials can be kept in a good balance, and achieves the goal of sustainable development.

[0036] The data collection module includes a usage record collection module and a loading information collection module. The usage record collection module is used to obtain information on used building materials; the loading information collection module is used to obtain detailed information on the building material storage warehouse and the loading building material container.

[0037] The stacking control module includes a sampling module, a humidity analysis module and a stacking analysis module. The sampling module is used to obtain the humidity of building materials under the influence of different parameters through pre-detection of building materials in the warehouse; the humidity analysis module is used to predict the time and rate at which building materials reach different humidity levels based on the pre-detection results of the sampling module; the stacking analysis module is used to formulate plans for the stacking and subsequent processing of building materials based on the monitoring results of the humidity analysis module.

[0038] The humidity analysis module further includes a humidity classification submodule and a humidity prediction analysis submodule. The humidity analysis submodule is used to analyze the different states of humidity of building materials; the humidity prediction submodule is used to obtain relevant parameters of humidity of building materials under different states.

[0039] The output module includes a conveying control module and a communication module. The conveying control module is used to adjust and control the plan of building material conveying in real time; the communication module is used to remind staff to make reasonable use of the building materials in the warehouse.

[0040] In a preferred embodiment, the operation method of the warehouse management system mainly includes the following steps:

[0041] Step S1: The transport vehicle transports the construction materials to the construction site, and the workers pour the construction materials into the loading containers. The data acquisition module obtains the distribution of the construction material containers in the warehouse through the loading information acquisition module;

[0042] Step S2: The staff extracts building materials as samples, and the sampling module performs a sampling experiment on the building materials to obtain monitoring results of the building materials being damp;

[0043] Step S3: The humidity analysis module monitors the humidity of the building materials in the container and predicts detailed information on the time when the building materials will be dampened;

[0044] Step S4: The stacking analysis module controls the details of transporting and using the building materials based on the monitoring results of the moisture content of the building materials;

[0045] Step S5: Establish a usage record and return system for construction materials, and ensure the rational use and safe return of construction materials based on the planning results of the output module.

[0046] In step S1 of this embodiment, the data acquisition module analyzes the contact area between the warehouse and the outside world, groups the building material containers stacked in the warehouse, and arranges them from the closest to the warehouse door to the inside of the warehouse according to the arrangement of the building material containers in the warehouse. The distances from the warehouse door are R1, R2, ..., R V , where V is the number of rows of building material containers from one door opening side to the other side in the overhead view of the warehouse.

[0047] The warehouse is constructed with one side open for transporting construction materials and the other three sides closed to keep out moisture.

[0048] When water vapor invades the warehouse, the building materials stacked in the warehouse are attacked by the water vapor in turn. Since the building materials stacked in the warehouse are spaced at the same distance but at different distances from the warehouse, the contact time, humidity and contact area with the air will vary. The sampling instrument installed at the warehouse door can detect to the greatest extent the impact of the distance from the warehouse door on the rate of water vapor infecting the container. The problem of different degrees of moisture caused by differences in wind speed and water vapor propagation at different locations in the warehouse is taken into account, thereby improving the detection accuracy.

[0049] In step S2 of this embodiment, a sampling instrument is set up in the warehouse at a distance of L meters from the warehouse door, and M kilograms of building materials are spread flat in the sampling instrument. The sampling amount of building materials is sufficient to be stacked to a certain height in the sampling instrument, so that the system can detect the moisture changes of the building materials in the sampling instrument. The sampling module in the sampling container divides the sampling instrument into two layers according to the mass of the building materials. The upper layer of the sampling instrument is in contact with the air. The height of the upper and lower layers is h. The building materials in the sampling instrument gradually absorb water vapor. When the mass of the upper layer exceeds Q1 kilograms, the moisture ratio of the upper layer is 0. The amount of water vapor absorbed by the upper building materials will affect the building effect, and corresponding air drying operations are required before use. At this time, the quality of the lower layer is Q2, and the moisture ratio of the lower layer is Q2. The time displayed by the timing unit is S1; when the mass of the upper layer exceeds P1 kg, the moisture ratio of the upper layer is It is determined that the amount of water vapor absorbed by the upper building materials seriously affects the building effect, and this part cannot be used. The time displayed on the timing unit is S2.

[0050] When water vapor invades the container of building materials, the net weight of the container increases, and the mass of the upper layer of the sampling instrument exceeds Q1 kg. At this time, the mass of water vapor on the upper layer of the sampling instrument is (Q1-1) kg. The moisture ratio of the upper layer of the sampling instrument is The calculation method for other moisture ratios in the sampling module is similar.

[0051] In this embodiment, step S3 further includes:

[0052] Step S31: The building materials transported in batches are packed in containers. The height of the packing container is H. The container is divided into The height of each layer is h. The moisture ratio of the building materials on the Kth floor of the Cth row in the warehouse when the first floor reaches the safe moisture level line is Where 0<C≤V,λ≥0, C and K are positive integers;

[0053] Water vapor intrudes into building materials and spreads in a wave-like manner. When the mass of the container is mQ1, the average mass of water vapor absorbed by all building materials in the surface container reaches the level that affects the building effect. However, due to the distance of contact with air in the container, the water vapor absorption of building materials at different positions in the container is different. The water vapor absorption of the building material layer close to the air is greater than the rated value that affects the building effect; the water vapor absorption of the building material layer far from the air is less than the rated value of the building material.

[0054] Step S32: The time for the building materials of the second layer to reach the safe moisture level is The time when the building materials of the Kth layer reach the safe moisture level line

[0055]

[0056] In the sampling module, when the first layer of building materials reaches the safe moisture level line, the proportional difference between the second layer of building materials and the safe moisture level line is (η1-η2), and since the time for the first layer of building materials to reach the safe moisture level line from drying is S1, the speed at which the first and second layer of building materials reach the safe moisture level line from drying is approximately the same, so the second layer of building materials still needs to spend more time after the first layer of building materials reaches the safe moisture level line. The time to reach the safe moisture level line;

[0057] Similarly, when the K-1th floor building materials reach the safe moisture level line, the proportional difference between the Kth floor building materials and the safe moisture level line is (η1-λ), and since the time for the K-1th floor building materials to reach the safe moisture level line from drying is S1, the speed at which the K-1th floor building materials reach the safe moisture level line from drying is approximately the same as that of the Kth floor building materials. Therefore, after the K-1th floor building materials reach the safe moisture level line, the Kth floor building materials still need to spend The time to reach the safe moisture level line;

[0058] The time when the building materials of the second floor reach the dangerous moisture level is The time when the building materials of the Kth floor reach the dangerous moisture level line is

[0059] Step S33: When the degree F1 of the outside temperature drop within 1 hour is higher than 50% of the maximum temperature difference F of the day, where the maximum temperature difference is the maximum temperature of the day minus the current minimum temperature, the system determines that the speed of water vapor infecting the building materials has changed significantly. Within B hours before the outside temperature returns to 50% of the current temperature change, the speed of water vapor infecting the building materials is calculated as the current speed of water vapor infecting the building materials. times, the time when the Kth layer of building materials reaches the safe moisture level line At the same time, the time when the building materials of the Kth floor reach the dangerous moisture level line is

[0060] Under normal circumstances, the rate at which building materials are infected by water vapor between dryness and the safe moisture level is Therefore, the rate of excess infection at the accelerated rate of water vapor infecting building materials within B hours is Similarly, the rate at which building materials are infected by water vapor between the safe moisture level line and the dangerous moisture level line is Therefore, the rate of excess infection at the accelerated rate of water vapor infecting building materials within B hours is

[0061]

[0062] Since the exposure above the loading container is affected by water vapor much faster than the speed at which water vapor penetrates the container, the humidity of building materials at different heights in the loading container will vary over time. By considering the dynamic impact of external temperature on the rate at which water vapor infects building materials, the accuracy of monitoring the moisture level of building materials inside the loading container is further guaranteed, solving the problem of inaccurate monitoring caused by existing technology that monitors the overall humidity of the loading container. At the same time, timely regulation of the use of building materials is carried out, which improves the quality requirements of construction and minimizes the damage and waste of building materials due to failure to monitor them in a timely and accurate manner.

[0063] In this embodiment, step S4 further includes:

[0064] Step S41: The requirement for building materials to be stacked in the warehouse is that a maximum of A% of the building materials can be damaged. After the building materials are transported in batches and stored in containers, of the building materials will be After 15 days, it reaches the safe moisture level line; of the building materials will be After a few days, the dangerous moisture level was reached;

[0065] Step S42: When the ratio of the dryness of the building materials in the container to the safe moisture level line is higher than 70%, it is determined that the dryness of the current container is good and other building materials are used first;

[0066] Step S43: When the ratio of the dryness of the building materials in the container to the safe moisture level line is lower than 70%, it is determined that the current container is damp, and the building materials are used first;

[0067] When the ratio of building materials in the container between the safe moisture level line and the dangerous moisture level line is higher than 50% and the ratio of building materials at the dangerous moisture level line exceeds 0.8A%, the communication module will prompt the staff at the shipping place to reduce the transportation volume of building materials and increase the transportation frequency of building materials while ensuring that the total transportation volume of building materials remains unchanged.

[0068] The stacking analysis module classifies the building materials in the warehouse based on the prediction results of the humidity analysis module, effectively reducing the adverse effects of differences in humidity caused by different transportation times and placement in the warehouse. At the same time, the communication module's reminders to the staff at the shipping location can timely control the amount of building materials in the warehouse, ensuring that the usage and storage quantities of building materials are kept in a good balance.
