The material pile three-dimensional model construction module constructs the position information of the gypsum material pile in the gypsum warehouse and the three-dimensional volume of each gypsum material pile based on the surface point cloud set of objects in the gypsum warehouse area. The material pile three-dimensional model construction module constructs a three-dimensional model of the gypsum material pile in the warehouse based on the position information of each gypsum material pile, the type of gypsum material in each gypsum material pile and the three-dimensional volume of each gypsum material pile.

[0014] As a preferred solution of the present invention, the processing system sets a priority for each outbound vehicle in the outbound vehicle operation module based on the outbound demand input module, and selects the outbound vehicle with the highest priority as the material grabbing vehicle;

[0015] The influencing conditions for setting the priority of each outbound vehicle are:

[0017] Based on the stacking time of gypsum materials in different material pits in the selected gypsum storage partition, the gypsum storage partition corresponding to the gypsum material pit with the longest current stacking time is selected again according to the first-in-first-out principle;

[0018] Based on the working status of the inbound crane and / or outbound crane in the reselected gypsum warehouse partition, the outbound crane corresponding to the gypsum warehouse partition is finally selected.

[0019] As a preferred solution of the present invention, the grabbing point selection module determines the grabbing center point of each grabbing of the outbound vehicle based on the material pile contour of the gypsum material pile in the warehouse updated in real time by the scanning module, so that the grab bucket of the outbound vehicle is in a full state;

[0024] Step 300, regulate the selected outbound crane to run according to the set outbound material picking and handling route, and regulate the outbound material picking times of the outbound crane according to the comparison result of the weight of the material picked up by the outbound crane each time and the material demand weight of the production line, until the total outbound weight of the outbound crane is the same as the material demand weight of the production line.

[0025] As a preferred solution of the present invention, the gypsum materials are divided into different areas according to the types of gypsum materials when entering the warehouse, and the gypsum materials are divided into different pits according to the amount of gypsum materials entering the warehouse, so that different types of gypsum materials are piled in different areas of the gypsum warehouse, and the volumes of gypsum materials piled in different pits are the same;

[0026] The scanning module in the gypsum warehouse repeatedly scans the gypsum pile in the gypsum warehouse, determines the position information of each gypsum pile in the gypsum warehouse and the distribution volume of each gypsum pile, and constructs a three-dimensional model of the gypsum pile.

[0027] As a preferred solution of the present invention, in step 200, the method for selecting the outbound crane and the gypsum material pile for outbound material collection based on the material category information and the material required weight is as follows:

[0028] According to the material category information corresponding to the gypsum board manufacturing production line and the gypsum stockpile 3D model, determine the gypsum warehouse partition with the material category information;

[0029] When more than two gypsum warehouse partitions have the material category information at the same time, determine whether there are inbound cranes and / or outbound cranes operating in all gypsum warehouse partitions;

[0030] Select the gypsum storage partition corresponding to the inbound vehicle and outbound vehicle that are not in operation as the outbound material collection target area;

[0031] According to the required weight of the materials, a gypsum material pile that meets the required weight of the materials is selected from the target area for material extraction and dispatch, and according to the principle of first-in-first-out, a gypsum material pile with the longest stacking time is selected from the gypsum material piles as the material pile for discharge;

[0032] An outbound crane in an idle and non-working state in the gypsum warehouse partition where the outbound material pile is located is selected as the transport object.

[0033] As a preferred solution of the present invention, in step 200, the position of the material pile for discharge in the gypsum warehouse is determined based on the three-dimensional model of the gypsum material pile, and the material collection and transportation route of the selected outbound vehicle is determined.

[0034] As a preferred solution of the present invention, in step 300, the outbound vehicle operates according to the set outbound material collection transportation route to collect materials, and adjusts the grabbing mode of the outbound vehicle for each material collection in sequence according to the modified material collection mode. The specific implementation method is:

[0035] The scanning module is used to update the material pile contour of the outgoing material pile in real time, the grabbing sequence of the outgoing vehicle is determined based on the material pile contour and the stacking time, and the center point of each grabbing of the outgoing vehicle is corrected according to the grabbing sequence.

[0036] As a preferred solution of the present invention, the method for determining the grabbing order of the outbound vehicle for each material grabbing and correcting the center point of each grabbing of the outbound vehicle according to the grabbing order is as follows:

[0037] Determine the stacking order of gypsum materials in each material pit when the gypsum materials are put into the warehouse by the warehouse-entry vehicle, and form the stacking direction of the gypsum materials in each material pit according to the warehouse-entry time of the gypsum materials in each material pit;

[0038] According to the priority order of first in, first out, the material grabbing order of the outbound crane is selected to be the same as the gypsum material inbound stacking direction, and the gypsum material inbound stacking direction is used as the material grabbing order of the outbound crane;

[0039] Each time the outbound crane grabs gypsum material, the material picking center point of the outbound crane is changed from high to low based on the real-time updated material pile profile of the outbound material pile, so as to ensure that the gypsum material grabbed by the outbound crane fills the grab bucket each time.

[0040] Compared with the prior art, the present invention has the following beneficial effects:

[0041] The outbound material collection management work of the present invention is based on the gypsum material quality of each gypsum partition of the incoming material pile, the gypsum material volume of each material pit and the stacking time of the gypsum material pile in each material pit. The outbound crane and the gypsum material pile are selected according to the principle of first in, first out. The selected outbound crane and gypsum material pile can form an outbound material collection transportation route, thereby realizing fully automated intelligent outbound work and realizing automated management of the outbound material collection of gypsum materials in the gypsum warehouse.

[0047] 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.

[0048] like Figure 1 As shown, the present invention provides a warehouse-out material collection management and control system based on gypsum material distribution information, including a processing system 1, a warehouse-out demand input module 2, a material pile three-dimensional model construction module 3, a warehouse-out driving operation module 4 and a material grabbing point selection module 5.

[0049] The processing system 1 acts as a coordinating center. Based on the distribution information of the gypsum material pile and the material demand of the production line, it selects the corresponding outbound crane and the corresponding gypsum material pile. After the outbound crane and the gypsum material pile are selected, an outbound transportation route for the outbound crane can be formed.

[0050] The specific implementation modules for selecting the outbound crane and the corresponding gypsum pile are:

[0051] The outbound demand input module 2 is in communication connection with the processing system 1 , and is used to input the material requirements of the production line, including material category information and material required weight.

[0052] The material pile three-dimensional model building module 3 is in communication connection with the processing system 1 , and the processing system 1 selects the corresponding material pile for discharge from the material pile three-dimensional model building module 3 based on the material requirement weight and material category information of the discharge requirement input module 2 .

[0053] The outbound crane operation module 4 is in communication with the processing system 1, and the processing system 1 is used to obtain the operation status of each outbound crane, and the processing system 1 selects the corresponding outbound crane from the outbound crane operation module 4 based on the selected outbound material pile.

[0054] The material grabbing point selection module 5 is in communication connection with the processing system 1 , and the processing system 1 determines the material grabbing point for each material grabbing based on the distribution form of the gypsum material pile of the material pile three-dimensional model construction module 3 .

[0055] The processing system 1 constructs the stacking position information and distribution information of each gypsum material pile through the material pile three-dimensional model construction module 3. The processing system 1 selects the corresponding gypsum material pile as the outgoing material pile based on the material demand of the production line input by the outgoing demand input module 2. The processing system 1 selects the outgoing crane based on the corresponding position of the outgoing material pile in the gypsum warehouse and the outgoing crane operation module 4, and controls the outgoing crane to take materials out of the outgoing material pile according to the grabbing point of each grabbing.

[0056] It should be noted that the gypsum materials in the gypsum warehouse are stacked in different material pits according to different categories so as to divide the gypsum materials by category. That is, when the gypsum materials are put into the warehouse for stacking, the partition of the gypsum warehouse where the gypsum materials to be put into the warehouse need to be stacked is first determined based on the identified category of the gypsum materials to be put into the warehouse, and then the material pit in the partition of the gypsum warehouse where the gypsum materials to be put into the warehouse need to be stacked is determined based on the volume of gypsum materials in each material pit of the partition of the gypsum warehouse. Thus, based on the gypsum partitions and the stacking pits, the position information of the gypsum materials to be put into the warehouse after entering the warehouse is determined, and based on the entry time point of the gypsum materials after entering the warehouse, the stacking time of each gypsum material pit in the gypsum warehouse is determined.

[0057] The outbound material collection management work in this embodiment is based on the gypsum material quality of each gypsum partition of the incoming material pile, the gypsum material volume of each material pit and the stacking time of the gypsum pile in each material pit. The outbound crane and the gypsum material pile are selected according to the principle of first in, first out. The selected outbound crane and gypsum material pile can form an outbound material collection transportation route, thereby realizing fully automated intelligent outbound work and realizing automated management of gypsum material outbound collection in the gypsum warehouse.

[0058] The processing system 1 sets a priority for each outbound vehicle in the outbound vehicle operation module 4 based on the outbound demand input module 2, and selects the outbound vehicle with the highest priority as the material grabbing vehicle;

[0059] Among them, the influencing conditions for setting the priority of each outbound vehicle are:

[0060] The material category information of the production line input in the outbound demand input module 2 selects the gypsum warehouse partition;

[0061] Based on the stacking time of gypsum materials in different material pits in the selected gypsum storage partition, the gypsum storage partition corresponding to the gypsum material pit with the longest current stacking time is selected again according to the first-in-first-out principle;

[0062] Based on the working status of the inbound crane and / or outbound crane in the reselected gypsum warehouse partition, the outbound crane corresponding to the gypsum warehouse partition is finally selected.

[0063] According to the material category information and the material weight of the production line, the outbound driving priority in the gypsum partition is set in sequence. Among them, the outbound driving priority of the gypsum storage partition that meets the material category information and the material weight of the production line is relatively high.

[0064] Then, when there are more than two gypsum pits that meet the material category information and material weight of the production line, the priority of the outbound vehicles with higher priority is set again based on the gypsum stacking time of each gypsum pit;

[0065] Determine the operating status of the incoming vehicle and / or outgoing vehicle in the gypsum material partition where the outgoing vehicle with the secondary priority is located, and set the highest priority for the outgoing vehicle in the gypsum material partition with the least number of operating states.

[0066] After the above-mentioned priority setting work, the outbound vehicle for gypsum material extraction and the gypsum material pile for gypsum material extraction can be selected to form a specific gypsum material transportation route.

[0067] The specific working process of the outbound material collection management system is as follows:

[0068] The outbound material management system is formed with an interactive user interface, and the type of gypsum material and the weight of gypsum material required for the production line for manufacturing gypsum board are specifically input in the interactive user interface through the outbound demand input module 2;

[0069] The processing system 1 determines the gypsum material pile contour of each material pit in each quality zone in the gypsum warehouse based on the material pile three-dimensional model building module 3, and determines the gypsum material volume in the material pit based on the gypsum material pile contour;

[0070] The processing system 1 determines the gypsum warehouse partition corresponding to the material pit that meets the gypsum material type and gypsum material weight based on the gypsum material type and gypsum material weight required by the production line and the gypsum material volume in each material pit;

[0071] The processing system 1 determines the operation status of the inbound and outbound vehicles corresponding to each gypsum storage partition based on the outbound vehicle operation module 4. When there are more than two gypsum storage partitions corresponding to the material pits that meet the gypsum material category and gypsum material weight, the outbound vehicle in the gypsum storage partition corresponding to the inbound and outbound vehicles without operation is preferentially selected as the outbound material collection object;

[0072] The selected outbound crane is regulated to carry out outbound material picking work along the selected gypsum material pile, and each time the material is picked up, the grabbing center position of the grabbing bucket of the outbound crane is corrected through the grabbing point selection module 5, so that the grabbing bucket is filled as much as possible each time the material is grabbed.

[0073] In order to construct the material pile three-dimensional model construction module 3, the gypsum warehouse is provided with a scanning module which can update the material pile contour of the gypsum material pile in the warehouse in real time. The scanning module is used to obtain a point cloud set of the surface of objects in the gypsum warehouse area. The material pile three-dimensional model construction module 3 constructs the position information of the gypsum material pile in the gypsum warehouse and the three-dimensional volume of each gypsum material pile based on the point cloud set of the surface of objects in the gypsum warehouse area. The material pile three-dimensional model construction module 3 constructs the three-dimensional model of the gypsum material pile in the warehouse based on the position information of each gypsum material pile, the type of gypsum material in each gypsum material pile and the three-dimensional volume of each gypsum material pile.

[0074] The grabbing point selection module 5 determines the grabbing center point of each grabbing of the outbound vehicle based on the material pile contour of the gypsum material pile in the warehouse updated in real time by the scanning module, so that the grab bucket of the outbound vehicle is full and the grabbing point of each grabbing of the outbound vehicle is the high point of the gypsum material pile.

[0075] It should be noted that when gypsum materials are put into storage, they are divided into partitions and stacked according to the types of gypsum materials, and when gypsum materials are put into storage, they are divided into material pits and stacked according to the storage volume, so that different types of gypsum materials are stacked in different partitions of the gypsum warehouse, and the volumes of gypsum materials stacked in different material pits are the same. The scanning module in the gypsum warehouse repeatedly scans the gypsum piles in the gypsum warehouse, and determines the position information of each gypsum pile in the gypsum warehouse and the distribution volume of each gypsum pile, so as to construct a three-dimensional model of the gypsum pile.

[0076] The present embodiment provides a method for managing the outbound material collection of the outbound material collection management control system for the distribution information of gypsum materials. The outbound material collection management work is closely related to the inbound material collection work. Figure 2 As shown, the specific steps include:

[0077] Step 100: input the material requirements of the gypsum board production line, including material category information and material required weight;

[0078] Step 200: determine the distribution information of the gypsum material pile in the gypsum warehouse and construct a 3D model of the gypsum material pile, and select the outbound vehicle and the outbound material pile for outbound material collection based on the material category information, the required material weight and the gypsum material pile stacking time;

[0079] Step 300, regulate the selected outbound crane to run according to the set outbound material picking and handling route, and regulate the outbound material picking times of the outbound crane according to the comparison result of the weight of the material picked up by the outbound crane each time and the material demand weight of the production line, until the total outbound weight of the outbound crane is the same as the material demand weight of the production line.

[0080] The warehouse material collection management method provided in this embodiment selects the gypsum material piles that meet the material category information and material weight requirements through an automated processing process of the gypsum material pile distribution information in the gypsum warehouse after the user inputs the material requirements of the gypsum board production line, and selects the outgoing material piles according to the first-in-first-out principle in combination with the stacking time of all gypsum material piles.

[0081] When the outgoing material piles are in different gypsum storage partitions, based on the operating status of the inbound crane and the outbound crane of the corresponding gypsum storage partition, the outbound crane in the gypsum storage partition with the least operating status is selected as the outbound crane for outbound material collection.

[0082] The selected outbound crane operates automatically according to the set outbound material collection and transportation route until the total outbound weight of the outbound crane is the same as the material demand weight of the production line.

[0083] In step 200, the method for selecting the outbound crane and the gypsum material pile for outbound material collection based on the material category information and the material requirement weight is as follows:

[0084] According to the material category information corresponding to the gypsum board manufacturing production line and the gypsum stockpile 3D model, determine the gypsum warehouse partition with the material category information;

[0085] When more than two gypsum warehouse partitions have the material category information at the same time, determine whether there are inbound cranes and / or outbound cranes operating in all gypsum warehouse partitions;

[0086] Select the gypsum storage partition with the least number of inbound and outbound vehicles in operation as the target area for outbound material collection;

[0087] According to the required weight of the material, the gypsum material piles meeting the required weight are selected from the target area for material removal from the warehouse, and according to the principle of first in first out, the gypsum material pile with the longest stacking time is selected from the gypsum material piles as the material pile for material removal;

[0088] The outbound crane that is idle and not working in the gypsum warehouse partition where the outbound material pile is located is selected as the transportation object.

[0089] Based on the three-dimensional model of the gypsum stockpile, the position of the outgoing material pile in the gypsum warehouse is determined, and the outgoing material picking and transportation route of the selected outgoing vehicle is determined.

[0090] In step 300, the outbound vehicle runs according to the set outbound material collection transportation route to collect materials, and adjusts the grabbing mode of each material collection by the outbound vehicle in sequence according to the modified material collection mode. The specific implementation method is as follows:

[0091] The scanning module is used to update the material pile contour of the outgoing material pile in real time, and the grabbing order of the outgoing crane is determined based on the material pile contour and stacking time, and the center point of each grabbing of the outgoing crane is corrected according to the grabbing order.

[0092] Determine the grabbing order of each material pick-up by the outbound driving, and correct the center point of each grabbing by the outbound driving according to the grabbing order:

[0093] Determine the stacking order of gypsum materials in each material pit when the gypsum materials are put into the warehouse by the warehouse-entry vehicle, and form the stacking direction of the gypsum materials in each material pit according to the warehouse-entry time of the gypsum materials in each material pit;

[0094] According to the priority order of first in, first out, the order of picking up materials by the outbound crane is the same as the direction of the gypsum material inbound stacking. The direction of the gypsum material inbound stacking is used as the order of picking up materials by the outbound crane.

[0095] Each time the outbound crane grabs gypsum material, the center point of the outbound crane is changed from high to low based on the real-time updated material pile profile of the outbound material pile, so as to ensure that the gypsum material grabbed by the outbound crane fills the grab bucket each time.

[0096] The automated management process of the above-mentioned outbound material collection management method is as follows:

[0097] Determine the material to be picked up: Based on the user input information, determine the material category information required for the gypsum board manufacturing production line, as well as the material requirement weight corresponding to each material category.

[0098] Determine the material-retrieving area and outbound vehicle: Determine the gypsum warehouse partition area corresponding to the material category information, determine whether there is an overhead crane operating in the gypsum warehouse partition area, exclude the gypsum warehouse partition area with a large number of operations, and determine whether there is enough material in the remaining gypsum warehouse partition area based on the required material weight, and determine the material-retrieving area and the outbound vehicle in the material-retrieving area based on the first-in-first-out principle of gypsum materials or other priority principles of the material yard.

[0099] Determine the material picking strategy: The outbound vehicle in the material picking area shall follow the material picking process requirements, straight picking, top-down cross-section picking and the material pile outline generated by the material pile imaging, and determine the picking order in combination with the stacking direction of the gypsum material entering the warehouse. Follow the principle of giving priority to picking up materials from high places and keeping the material pile in the material picking area as flat as possible, and generate the center point of each grab for this material picking task.

[0100] Correct the material picking process: Use the scanning module to update the material pile outline in the picking area in real time. After grabbing the material, there will inevitably be a slight landslide. Therefore, after each grab, the center point of the next grab must be corrected to ensure that the grab bucket is filled with material each time, avoid oblique grabbing, and automatically weigh the weight of each grabbed material. When the total weight of the picked material meets the required weight, the material picking task is automatically ended.

[0101] The outbound material collection management work in this embodiment is based on the gypsum material quality of each gypsum partition of the incoming material pile, the gypsum material volume of each material pit and the stacking time of the gypsum pile in each material pit. The outbound crane and the gypsum material pile are selected according to the principle of first in, first out. The selected outbound crane and gypsum material pile can form an outbound material collection transportation route, thereby realizing fully automated intelligent outbound work and realizing automated management of gypsum material outbound collection in the gypsum warehouse.

The protection scope of the present application is defined by the claims.

The material handling management method according to claim 5, characterized in that: When gypsum materials are put into storage, they are divided into different areas according to the types of gypsum materials, and the gypsum materials are divided into different pits according to the amount of gypsum materials put into storage, so that different types of gypsum materials are piled in different areas of the gypsum storage, and the volume of gypsum materials piled in different pits is the same; The scanning module in the gypsum warehouse repeatedly scans the gypsum pile in the gypsum warehouse, determines the position information of each gypsum pile in the gypsum warehouse and the distribution volume of each gypsum pile, and constructs a three-dimensional model of the gypsum pile.

7. The method for managing materials out of warehouse according to claim 6, characterized in that: In step 200, the method for selecting the outbound crane and the gypsum material pile for outbound material collection based on the material category information and the material requirement weight is as follows: According to the material category information corresponding to the gypsum board manufacturing production line and the gypsum stockpile 3D model, determine the gypsum warehouse partition with the material category information; When more than two gypsum warehouse partitions have the material category information at the same time, determine whether there are inbound cranes and / or outbound cranes operating in all gypsum warehouse partitions; Select the gypsum storage partition corresponding to the inbound vehicle and outbound vehicle that are not in operation as the outbound material collection target area; According to the material demand weight, gypsum material piles meeting the material demand weight are selected from the target area for material removal, and according to the first-in-first-out principle, the gypsum material pile with the longest stacking time is selected from the gypsum material piles as the material pile for material removal; An outbound crane in an idle and non-working state in the gypsum warehouse partition where the outbound material pile is located is selected as the transport object.

8. The material handling management method according to claim 7, characterized in that: In step 200, the position of the material pile as the outgoing material in the gypsum warehouse is determined based on the three-dimensional model of the gypsum material pile, and the outgoing material collection and transportation route of the selected outgoing vehicle is determined.

9. The method for managing materials out of warehouse according to claim 6, characterized in that: In step 300, the outbound vehicle operates according to the set outbound material collection transportation route to collect materials, and adjusts the grabbing mode of each material collection of the outbound vehicle in sequence according to the modified material collection mode. The specific implementation method is: The scanning module is used to update the material pile contour of the outgoing material pile in real time, the grabbing sequence of the outgoing vehicle is determined based on the material pile contour and the stacking time, and the center point of each grabbing of the outgoing vehicle is corrected according to the grabbing sequence.

10. The method for managing materials out of warehouse according to claim 6, characterized in that: The method for determining the grabbing order of each material grabbing by the outbound vehicle and correcting the center point of each grabbing by the outbound vehicle according to the grabbing order is as follows: Determine the stacking order of gypsum materials in each material pit when the gypsum materials are put into the warehouse by the warehouse-entry vehicle, and form the stacking direction of the gypsum materials in each material pit according to the warehouse-entry time of the gypsum materials in each material pit; According to the priority order of first in, first out, the material grabbing order of the outbound crane is selected to be the same as the gypsum material inbound stacking direction, and the gypsum material inbound stacking direction is used as the material grabbing order of the outbound crane; Each time the outbound crane grabs gypsum material, the material picking center point of the outbound crane is changed from high to low based on the real-time updated material pile profile of the outbound material pile, so as to ensure that the gypsum material grabbed by the outbound crane fills the grab bucket each time.
