[0027] Please refer to Figure 1 , which shows a schematic diagram of a material management system provided by an embodiment of the present application. The material management system may include: a material control system 11 and a material transportation system 12.

[0028] The material control system 11 is used to manage materials in a unified manner. In the embodiment of the present application, the material control system 11 monitors the remaining amount of materials of the material user, and when the remaining amount of materials of the material user cannot meet the production demand, the material is replenished in time to ensure the continuity of production, thereby improving production efficiency. Optionally, the material control system 11 can be a server or a collection of multiple servers, which is not limited in the embodiment of the present application.

[0029] The material transportation system 12 is used to transport materials. In the embodiment of the present application, after a material replenishment request is generated, the material transportation system 12 transports the materials from the material replenishment area to the corresponding material fetching area. Optionally, the material transportation system 12 includes one or more automated guided vehicles (AGVs), each of which is equipped with at least one storage cabinet for storing materials. For example, Figure 2 As described, the automatic guided transport vehicle 21 is loaded with a plurality of storage cabinets, including a material discharging cabinet 22 and a recycling cabinet 23. The material discharging cabinet 22 is used to store new materials, and the recycling cabinet 23 is used to store old materials, and the old materials refer to the residual materials left after the new materials are used. Taking the silver paste as an example, the new material refers to the silver paste that has not been taken after storage, and the old material refers to the silver paste remaining on the barrel cover, barrel wall and barrel bottom after the silver paste is taken. Moreover, each storage cabinet includes a weighing sensor 24, a hinge 25 and a door lock 26. Optionally, when storing materials, the material discharging cabinet 22 opens the cabinet door through the hinge 25, and the weighing sensor 24 therein records the weight of the stored materials, and the cabinet door is locked by the door lock 26 after closing the cabinet door, thereby completing a material storage; when recycling materials, the recycling cabinet 23 opens the cabinet door through the hinge 25, and the weighing sensor 24 therein records the amount of recycled materials, and the cabinet door is locked by the door lock 26 after closing the cabinet door.

[0030] Optionally, the material regulation system 11 and the material transportation system 12 are connected via a network.

[0031] It should be noted that the above introduction to the material management system is only exemplary and explanatory. In actual applications, the material management can be flexibly set and adjusted according to the actual situation. Exemplarily, the material regulation system 11 and the material transportation system 12 can be set in the same device. For example, a material management service section can be set in an automated guided vehicle to achieve self-management of the automated guided vehicle.

[0032] Please refer to Figure 3 , which shows a flowchart of the material management method provided by an embodiment of the present application. This method is applied to Figure 1 the server in the material regulation system 11 shown, and can also be applied to the material management service section in the automated guided vehicle (hereinafter collectively referred to as "computer device"). This method may include the following steps (301~304):

[0033] Step 301, obtain the remaining amount of materials of the material user.

[0034] The material user is the material using party, and the material user includes at least one material using user, and the material using user can also be called a product production worker. The material refers to the raw materials required for product production. In an exemplary embodiment, the material refers to precious materials such as silver paste. The remaining amount of materials refers to the weight of the materials that have not been put into production.

[0035] In the embodiment of the present application, during the product production process, the computer device detects the usage situation of the materials in real time to obtain the remaining amount of materials of the material user. Optionally, the computer device detects the usage situation of the materials in real time with the material using user as the minimum unit, obtains the remaining amount of materials of each material using user, and then obtains the remaining amount of materials of the above-mentioned material user.

[0036] Step 302, generate a material replenishment request when the remaining amount of materials of the material user cannot meet the production demand.

[0037] The material replenishment request is used to request replenishment of materials when the remaining amount of materials cannot meet the production demand. In the embodiment of the present application, after the computer device obtains the remaining amount of materials of the above-mentioned material user, it determines the remaining amount of materials of the material user based on the production demand, and generates a material replenishment request when the remaining amount of materials of the material user cannot meet the production demand.

[0038] Optionally, the computer device determines whether to generate a material replenishment request based on the material usage amount of the material user. In an exemplary embodiment, the above step 302 includes the following steps:

[0039] 1. When the remaining amount of materials of the material-using party cannot meet the production requirements, obtain the identity information of the material-using party;

[0040] 2. Based on the identity information of the material-using party, obtain the material usage amount of the material-using party;

[0041] 3. When the material usage amount of the material-using party is less than the fourth threshold, generate a material replenishment request.

[0042] The material usage amount of the material-using party refers to the total weight of the materials taken out by the material-using party from the storage cabinet of the automatic guided vehicle within the first time period. Herein, the first time period can be any time period, which can be flexibly set and adjusted according to the actual situation, and the embodiments of the present application do not make any limitations thereto. For example, the first time period is the time period indicated by one hour before the current moment; or, the first time period is the time period indicated by one day before the current moment; or, the first time period is the time period indicated from a certain moment of the day to the current moment, and this certain moment can be any moment before the current moment; and so on.

[0043] The identity information of the material-using party is used to indicate the unique identity of the material-using party. In the embodiments of the present application, when the remaining amount of materials of the material-using party cannot meet the production requirements, the computer device obtains the identity information of the material-using party. Optionally, the computer device obtains the identity information of the material-using party through an image acquisition device and image detection technologies (such as face recognition technology, workstation recognition technology, etc.). It should be noted that when the material-using party includes multiple material-using users, the identity information of the material-using party includes the identity information corresponding to each material-using user respectively.

[0044] In the embodiments of the present application, after the computer device obtains the identity information of the material-using party, based on the identity information of the material-using party, it obtains the material usage amount of the material-using party. Optionally, the computer device stores material withdrawal information, and this material withdrawal information is used to record the corresponding relationship between the identity information and the withdrawn material information, and the material information includes the material weight. Optionally, after the computer device obtains the identity information of the material-using party, based on the identity information of the material-using party, it obtains the material usage amount of the material-using party from the corresponding relationship included in the material withdrawal information. Optionally, the above-mentioned material information further includes at least one of the following: material ID (Identity document), material model, material batch, etc.

[0045] Optionally, the automatic guided transport vehicle has an information scanning section and a weighing sensor is provided in the storage cabinet. When the material user takes out the material, the identity information of the material user is obtained through the information scanning section, and the weight of the taken out material is recorded through the weighing sensor. Optionally, the data recorded by the information scanning section and the weighing sensor are transmitted to the computer device in real time, and the computer device generates the above-mentioned material taking out information through the acquired data. Optionally, the above-mentioned information scanning section can also obtain related material information when taking out the material, and the related material information includes but is not limited to at least one of the following: material ID, material model, material batch, etc.

[0046] In the embodiment of the present application, the computer device obtains the material usage of the material user, compares the material usage of the material user with the fourth threshold, and generates a material replenishment request when the material usage of the material user is less than the fourth threshold; conversely, when the material usage of the material user is greater than or equal to the fourth threshold, a third warning message is generated, and the third warning message is used to indicate that the material user has taken out too much material in the first time period. Among them, the fourth threshold can be set arbitrarily, and the fourth threshold can be flexibly set and adjusted according to actual conditions, and the embodiment of the present application does not limit this.

[0047] Step 303: Based on the material replenishment request, control the automatic guided vehicle to move to the material replenishment area.

[0048] The material replenishment area refers to an area for replenishing materials. For example, the material replenishment area can be a warehouse, near a warehouse management staff position, or an area where materials are located in the warehouse. In an embodiment of the present application, after obtaining the above-mentioned material replenishment request, the computer device controls the automatic guided transport vehicle to move to the material replenishment area based on the material replenishment request. Among them, the automatic guided transport vehicle is loaded with at least one storage cabinet for storing materials.

[0049] Optionally, the material replenishment request includes the category of the material to be replenished, and the computer device determines the category of the material to be replenished based on the material replenishment request, and then controls the automatic guided transport vehicle to move to the material replenishment area corresponding to the material category. Of course, in other possible implementations, the material replenishment request can also directly indicate the location of the material replenishment area.

[0050] Step 304, when it is determined that the material replenishment based on identity recognition is completed, control the automatic guided transport vehicle to move to the material retrieval area.

[0051] The material retrieval area refers to the area where materials are retrieved. Exemplarily, the material retrieval area can be near the workstations of the material users, near a production line that requires the use of materials, the central area of multiple production lines that require the use of materials, etc. In the embodiments of the present application, after the computer device moves to the material replenishment area, when it is determined that the material replenishment based on identity recognition is completed, the computer device controls the automatic guided vehicle to move to the material retrieval area.

[0052] The above identity recognition is used to determine whether the replenisher has the authority to replenish materials. Optionally, since different users have different material authorities, after the automatic guided vehicle moves to the material replenishment area, it determines whether the replenisher has the authority to replenish materials based on identity recognition. Then, when the replenisher has the authority to replenish materials, the storage cabinet is opened to enable the replenisher to replenish materials. After that, when the storage cabinet is closed, it is determined that the material replenishment is completed, and then the computer device controls the automatic guided vehicle to move to the material retrieval area. Optionally, the above identity recognition includes, but is not limited to, at least one of the following: face recognition, fingerprint recognition, voice recognition, access card recognition, etc.

[0053] Optionally, the material replenishment request includes the identity information of the material user. When the material replenishment is completed, the computer device controls the automatic guided vehicle to move to the material retrieval area corresponding to the material user.

[0054] In summary, in the technical solution provided by the embodiments of the present application, by detecting the remaining amount of materials of the material user, when the remaining amount of materials cannot meet the production requirements, a material replenishment request is generated to replenish the materials, that is, when there is a surplus of materials, the materials are replenished in a timely manner in combination with the production requirements, reducing the decrease in product output caused by the idleness of the production line or workers during the replenishment process and improving the product production efficiency; moreover, by using an automatic guided vehicle equipped with a storage cabinet to move between the material replenishment area and the material retrieval area to replenish materials, while saving human resources, identity recognition is introduced during the material replenishment process, and it is determined whether the user can replenish materials based on the identity authority. The replenishment of materials is reasonably controlled through the automatic guided vehicle, improving the safety during the material replenishment process, reducing the replenishment chaos caused by manual operations, and facilitating the automated replenishment of valuable materials, dangerous materials, etc.

[0055] In addition, since a large amount of material loss is often accompanied by a large amount of material usage, when it is determined that the remaining amount of materials cannot meet the production requirements, the material usage amount of the material user is obtained based on the identity information of the material user. Then, when the material usage amount is less than the fourth threshold, a material replenishment request is generated. While replenishing the materials in a timely manner, the material usage amount is restricted, and the material users with excessive material usage can be detected in a timely manner, which is convenient for subsequent detection of such material users, thereby reducing material waste indirectly.

[0056] Next, a specific introduction to the movement of the automatic guided transportation will be given.

[0057] In an exemplary embodiment, step 303 described above includes the following steps:

[0058] 1. Based on the material replenishment request, determine the identity information of the material user.

[0059] Optionally, the material replenishment request includes the identity information of the material user. In the embodiment of the present application, after the computer device obtains the above-mentioned material replenishment request, the identity information included in the material replenishment request is determined as the identity information of the material user.

[0060] 2. Based on the identity information of the material user, obtain the material loss amount of the material user.

[0061] The material loss amount of the material user refers to the total weight of the materials recovered by the material user through the storage cabinet of the automatic guided transport vehicle within the first time period. Among them, material recovery refers to the recovery of the materials remaining on the surface of the container after the materials are used. In the embodiment of the present application, after the computer device obtains the above-mentioned identity information of the material user, based on the identity information of the material user, the material loss amount of the material user is obtained. Optionally, the computer device stores material recovery information, which is used to record the correspondence between the identity information and the recovered material information, and the material information includes the material weight. Exemplarily, when the computer device obtains the material loss amount of the material user, based on the identity information of the material user, from the correspondence included in the material recovery information, the total weight of the materials recovered by the material user through the storage cabinet of the automatic guided transport vehicle within the first time period is determined as the material loss amount of the material user.

[0062] Optionally, the automatic guided transport vehicle has an information scanning section and a weighing sensor is provided in the storage cabinet. When recovering materials, the identity information of the material user is obtained through the information scanning section, and the weight of the recovered materials is recorded through the weighing sensor. Optionally, the data recorded by the information scanning section and the weighing sensor are transmitted to the computer device in real time, and the computer device generates the above-mentioned material recovery information through the obtained data. Optionally, the above-mentioned information scanning section can also obtain associated material information when recovering materials, and the associated material information includes but is not limited to at least one of the following: material ID, material model, material batch, etc. Optionally, the above-mentioned material information also includes but is not limited to at least one of the following: material ID, material model, material batch, etc.

[0063] 3. In the case where the material loss amount of the material user is less than the first threshold, control the automatic guided transport vehicle to move to the material replenishment area.

[0064] In an embodiment of the present application, after the computer device obtains the material loss amount of the above-mentioned material user, it compares the material loss amount of the material user with a first threshold. When the material loss amount of the material user is less than the first threshold, based on the identity information of the material user, it controls the automatic guided vehicle to move to the material replenishment area. The first threshold can be any value, and the first threshold can be flexibly set and adjusted according to the actual situation. The embodiments of the present application do not limit this.

[0065] In a possible implementation manner, when the computer device determines that the material loss amount of the material user is less than the first threshold, it immediately controls the automatic guided vehicle to move to the material replenishment area. In another possible implementation manner, when the computer device determines that the material loss amount of the material user is less than the first threshold, it determines whether to control the automatic guided vehicle to move to the material replenishment area based on the product production volume of the material user. The product production volume of the material user refers to the product weight / product quantity produced by the material user through the material. Optionally, a weighing sensor is set on the production line, and the computer device obtains the product production volume of the material user in real time through the weighing sensor; of course, in other possible implementation manners, the computer device can also obtain the product production volume of the material user in real time according to the image acquisition device and image detection technology.

[0066] Optionally, when the computer device determines that the material loss amount of the material user is less than the first threshold, based on the identity information of the material user, it obtains the product production volume of the material user within the first time period; further, when the product production volume of the material user meets the conditions, based on the identity information of the material user, it controls the automatic guided vehicle to move to the material replenishment area.

[0067] In a possible implementation manner, the computer device directly determines whether it meets the conditions through the product production volume. Optionally, after the computer device obtains the product production volume of the material user, it compares the product production volume with a fifth threshold; further, when the product production volume of the material user is greater than or equal to the fifth threshold, it determines that the product production volume of the material user meets the conditions; conversely, when the product production volume of the material user is less than the fifth threshold, it determines that the product production volume of the material user does not meet the conditions. The above-mentioned fifth threshold can be any value, and the fifth threshold can be flexibly set and adjusted according to the actual situation. The embodiments of the present application do not limit this.

[0068] In another possible implementation, the computer device determines the material utilization rate based on the product production volume, and then determines whether the product production volume meets the conditions based on the material utilization rate. Optionally, the computer device obtains the material usage amount of the material user based on the identity information of the material user. Exemplarily, the computer device obtains the material usage amount of the material user through the above-mentioned material extraction information; then, the computer device determines the material utilization rate of the material user based on the product production volume of the material user and the material usage amount of the material user; further, when the material utilization rate of the material user is greater than or equal to the third threshold, it is determined that the product production volume of the material user meets the conditions; conversely, when the material utilization rate of the material user is less than the third threshold, it is determined that the product production volume of the material user does not meet the conditions. Among them, the above-mentioned third threshold can be any value, and the fifth threshold can be flexibly set and adjusted according to the actual situation, and the embodiments of the present application do not limit this.

[0069] Optionally, the material utilization rate can also be referred to as the material utilization ratio, which is used to indicate the effective usage of the material during the usage process.

[0070] In one possible implementation, after the computer device obtains the product production volume of the above-mentioned material user, it obtains the actual material usage amount of the material user based on the product production volume of the material user; further, based on the ratio between the actual material usage amount of the material user and the material usage amount of the material user, it is determined as the material utilization rate of the material user. Among them, the actual material usage amount is used to indicate the weight of the material that is put into production and obtains the corresponding product among the extracted materials. Taking the material as silver paste as an example, the weight of the extracted silver paste (i.e., the material usage amount) is 1 kg, the weight of the silver product produced (i.e., the product production volume) is 0.99 kg, then the corresponding actual silver paste usage amount (i.e., the actual material usage amount) is 0.99 kg, and the silver paste utilization rate (i.e., the material utilization rate) is 99%.

[0071] In another possible implementation, after the computer device obtains the product production volume of the above-mentioned material user, it obtains the production prediction range of the material user based on the material usage amount of the material user; further, based on the relationship between the product production volume of the material user and the production prediction range, it is determined as the material utilization rate of the material user. Taking the material as silver paste as an example, the weight of the extracted silver paste (i.e., the material usage amount) is 1 kg, and the prediction range of the corresponding silver product (or silver-containing product) (i.e., the production prediction range) is 0 - 100 pieces. If the number of silver products (or silver-containing products) produced (i.e., the product production volume) is 99 pieces, then the silver paste utilization rate (i.e., the material utilization rate) is 99%.

[0072] Optionally, the above-mentioned silver product can be a product processed from silver paste as a single material; it can also be a product processed from silver paste as part of the material, such as forming a metal electrode on a photovoltaic cell by screen printing, etc., and the embodiments of the present application do not limit this.

[0073] Optionally, when the production volume of the product does not meet the conditions, the computer device generates a second warning message, which is used to indicate that there is waste of materials during the production process. Exemplarily, if the above material-using party includes at least one material-using user, when the computer device determines that the production volume of the product does not meet the production conditions, it respectively obtains the production data of each material-using user, and then based on the production data of each material-using user, determines the second over-quantity users whose production data is less than the sixth threshold, and generates a second warning message based on the identity information of the second over-quantity users. The second warning message includes the identity information of each second over-quantity user. Optionally, the above production data includes but is not limited to at least one of the following: product production volume, material usage rate. Among them, the above sixth threshold can be any value, and can be flexibly set and adjusted according to the actual situation, and the embodiments of the present application do not limit this.

[0074] Optionally, when the material loss of the material-using party is greater than or equal to the first threshold, the computer device generates a first warning message. The first warning message is used to indicate that there is waste during the material recycling process.

[0075] Optionally, if the above material-using party includes at least one material-using user, when the material loss of the material-using party is greater than the first threshold, the computer device respectively obtains the material loss of each material-using user; then based on the material loss of each material-using user, determines the first over-quantity users whose material loss is greater than the second threshold; afterwards, generates a first warning message based on the identity information of the first over-quantity users. The first warning message includes the identity information of each first over-quantity user. Among them, the above second threshold can be any value, and can be flexibly set and adjusted according to the actual situation, and the embodiments of the present application do not limit this.

[0076] In summary, in the technical solution provided by the embodiments of the present application, when the material loss is less than the first threshold, the automatic guided vehicle is controlled to move to the material replenishment area, and the material loss is used as a constraint condition before replenishment, which can timely detect large material losses before replenishment, improve the rigor of the automatic replenishment operation, and reduce material waste caused by irregular replenishment from the side; moreover, there is a corresponding relationship between the identity information and the material loss, which can reasonably detect and control the material loss, and is beneficial to solving the problem of chaotic material management.

[0077] In addition, when the material loss amount is greater than the first threshold, a first warning message is generated to indicate that there is waste in the material recycling process, facilitating subsequent timely handling of material waste during the recycling process, thereby reducing material waste during the recycling process. Moreover, the first warning message is generated based on the identity information of the user with excessive consumption, that is, the identity information of the user with excessive consumption can be traced and determined based on the first warning message, specifying the material waste situation to an individual and facilitating the control of material loss.

[0078] In addition, when the material loss amount is less than the first threshold, and further when the product production output meets the conditions, the automatic guided vehicle is controlled to move to the material replenishment area. Based on the material loss amount and in combination with the product production output, the replenishment operation is further restricted, further improving the rigor of the automatic replenishment operation. Moreover, using the material utilization rate to characterize the specific waste situation of materials during the production process can better control the material production process, timely detect unreasonable material waste during the product production process before replenishment, facilitating subsequent adjustment of product production, and thereby indirectly improving the product production rate.

[0079] It should be noted that the above introduction to the movement of the automatic guided vehicle is only exemplary and explanatory, and the acquisition steps of the above material loss amount and the above product production volume can be flexibly set and adjusted according to the actual situation. Exemplarily, in another possible implementation manner, step 303 includes the following steps:

[0080] 1. Based on the material replenishment request, determine the identity information of the material user.

[0081] 2. Based on the identity information of the material user, obtain the product production volume of the material user within the first time period.

[0082] 3. When the product production volume of the material user meets the conditions, control the automatic guided vehicle to move to the material replenishment area.

[0083] Optionally, the computer device determines the material utilization rate through the product production volume, and then determines whether the product production volume meets the conditions based on the material utilization rate. Optionally, the computer device obtains the material usage amount of the material user based on the identity information of the material user; then, the computer device determines the material utilization rate of the material user based on the product production volume and the material usage amount of the material user; further, when the material utilization rate of the material user is greater than or equal to the third threshold, it is determined that the product production volume of the material user meets the conditions; conversely, when the material utilization rate of the material user is less than the third threshold, it is determined that the product production volume of the material user does not meet the conditions. Optionally, when the product production volume does not meet the conditions, the computer device generates a second warning message, which is used to indicate that there is waste in the material during the production process.

[0084] Optionally, when the product production volume of the material-using party meets the conditions, further obtain the material loss volume of the material-using party based on the identity information of the material-using party. Then, when the material loss volume of the material-using party is less than the first threshold, control the automated guided vehicle to move to the material replenishment area. Optionally, when the material loss volume of the material-using party is greater than the first threshold, the computer device generates a first warning message. The first warning message is used to indicate that there is waste in the material recycling process.

[0085] It should be noted that the specific details not introduced in this example refer to the above text and will not be elaborated here.

[0086] Next, determine whether the remaining material volume of the material-using party meets the production requirements.

[0087] In an exemplary embodiment, before the above step 302, the following steps are further included:

[0088] 1. Obtain the material usage rate of the material-using party.

[0089] The material usage rate is used to indicate the consumption rate of the material per unit time. This unit time can be any value, such as 0.01 s, 0.1 s, 1 min, etc., and the embodiments of the present application do not limit this.

[0090] In a possible implementation manner, the computer device obtains the material usage rate of the material-using party based on the material usage volume of the material-using party. Optionally, the computer device takes the current moment as a reference, obtains the real-time material usage volume of the material-using party, and based on the real-time material usage volume of the material-using party, updates the material usage rate of the material-using party in real time to obtain the material usage efficiency of the material-using party. The real-time material usage volume of the material-using party refers to the total weight of the material taken out by the material-using party from the storage cabinet of the automated guided vehicle within the first interval duration. The first interval duration is less than or equal to the duration indicated by the above first time period, and this first interval duration can be any duration, such as 1 s, 10 min, 1 hour, 1 day, etc., and the embodiments of the present application do not limit this. Optionally, the computer device determines the ratio between the real-time material usage volume of the material-using party and the first interval duration as the material usage rate of the material-using party.

[0091] In another possible implementation, the computer device obtains the material usage rate of the material user based on the product production volume of the material user. Optionally, the computer device takes the current moment as a reference, obtains the real-time product production volume of the material user, and based on the real-time product production volume of the material user, updates the material usage rate of the material user in real time to obtain the material usage efficiency of the material user. The real-time product production volume of the material user refers to the weight / quality of the products produced by the material user within the second interval duration; the second interval duration is less than or equal to the duration indicated by the above first time period, and the second interval duration may be the same as or different from the above first interval duration, and the embodiments of the present application do not make any limitations in this regard. Optionally, after obtaining the real-time product production volume of the material user, the computer device estimates the corresponding actual material usage volume based on the real-time product production volume of the material user, and then determines the ratio between the actual material usage volume and the second interval duration as the material usage rate of the material user.

[0092] It should be noted that both the above first interval duration and the above second interval duration are greater than the above unit duration.

[0093] 2. Predict the amount of materials required by the material user within the second time period based on the material usage rate of the material user.

[0094] In the embodiments of the present application, after obtaining the material usage rate of the material user, the computer device predicts the amount of materials required by the material user within the second time period based on the material usage rate of the material user. Optionally, the computer device determines the product of the material usage rate of the material user and the duration indicated by the second time period as the amount of materials required by the material user.

[0095] Optionally, the duration indicated by the second time period is greater than or equal to the material replenishment duration of the automated guided vehicle. The material replenishment duration is determined according to the duration required for the automated guided vehicle to travel from the material retrieval area to the material replenishment area and then back from the material replenishment area to the material retrieval area. Exemplarily, the material replenishment duration is the duration required for the automated guided vehicle to travel from the material retrieval area to the material replenishment area and then back from the material replenishment area to the material retrieval area. It should be noted that the starting moment of the above second time period is the current moment.

[0096] 3. In the case where the remaining amount of materials of the material user is less than the amount of materials required by the material user, it is determined that the remaining amount of materials of the material user cannot meet the production requirements.

[0097] In an embodiment of the present application, after a computer device obtains the remaining amount of materials of the material-using party and the amount of materials required by the material-using party, it compares the remaining amount of materials of the material-using party with the amount of materials required by the material-using party. When the remaining amount of materials of the material-using party is less than or equal to the amount of materials required by the material-using party, it is determined that the remaining amount of materials of the material-using party cannot meet the production demand; on the contrary, when the remaining amount of materials of the material-using party is greater than the amount of materials required by the material-using party, it is determined that the remaining amount of materials of the material-using party can meet the production demand.

[0098] In summary, in the technical solution provided by the embodiment of the present application, the amount of materials required is predicted through the material usage rate. Then, when the remaining amount of materials is less than the required amount of materials, it is determined that the remaining amount of materials cannot meet the production demand. By obtaining the material usage rate in real time and considering the changes in the material usage rate under different conditions (such as time, environment, space, etc.), the timeliness and accuracy of the predicted required amount of materials are improved. Furthermore, the timeliness and accuracy of subsequent material production requests are improved. Moreover, the duration indicated by the second time period is greater than or equal to the material replenishment duration of the automated guided vehicle, ensuring that there is still enough material for production when the material replenishment request is generated, reducing the decline in product output caused by the idleness of the production line or workers during the material replenishment process, and thus improving the product production efficiency. Additionally, determining the duration indicated by the second time period based on the material replenishment duration helps to solve the problem of frequent material replenishment caused by too short a second time period, and further helps to solve the problem of excessive energy consumption of the automated guided robot caused by frequent material replenishment.

[0099] Next, a specific method for obtaining the remaining amount of materials of the material-using party will be introduced.

[0100] In an exemplary embodiment, step 301 above includes the following steps:

[0101] 1. Obtain the material usage amount of the material-using party and the total amount of materials stored in the automated guided vehicle.

[0102] In an embodiment of the present application, before the computer device obtains the remaining amount of materials of the material-using party, it obtains the material usage amount of the material-using party and the total amount of materials stored in the automated guided vehicle.

[0103] Optionally, a weighing sensor is provided in the storage cabinet of the automated guided vehicle. When storing materials, the weight of the stored materials is recorded by the weighing sensor. Correspondingly, when taking out materials, the weight of the taken-out materials can also be recorded by the weighing sensor.

[0104] Optionally, the weight data recorded by the above weighing sensor is transmitted to a computer device in real time. In an exemplary embodiment, when the computer device obtains the material usage of the material user, the total weight of the materials taken out by the material user from the storage cabinet of the automatic guided vehicle within the first time period is determined as the material usage of the material user; correspondingly, the computer device determines the total weight of the materials stored in the storage cabinet of the automatic guided vehicle within the first time period as the total amount of materials stored in the automatic guided vehicle.

[0105] Optionally, material extraction information is stored in the computer device, and the material extraction information is used to record the correspondence between the identity information and the extracted material information, and the material information includes the material weight. Exemplarily, when the computer device obtains the material usage of the material user, based on the identity information of the material user, the material usage of the material user is obtained from the correspondence included in the material extraction information.

[0106] Optionally, in order to reduce the device load, for the weight data transmitted by the weighing sensor, the computer device deletes the weight data before the first time period.

[0107] 2. Obtain the remaining amount of materials of the material user based on the material usage of the material user and the total amount of materials stored in the automatic guided vehicle.

[0108] In the embodiment of the present application, after the computer device obtains the material usage of the above-mentioned material user and the total amount of materials stored in the above-mentioned automatic guided vehicle, based on the material usage of the material user and the total amount of materials stored in the automatic guided vehicle, the remaining amount of materials of the material user is obtained.

[0109] In a possible implementation manner, the computer device determines the absolute value of the difference between the material usage of the material user and the total amount of materials stored in the automatic guided vehicle as the remaining amount of materials of the material user. Optionally, when the material user takes out materials through the above storage cabinet, the computer device determines that the material usage of the material user has changed, and updates the material usage of the material user in real time. Further, based on the updated material usage and the total amount of materials stored in the automatic guided vehicle, the remaining amount of materials of the material user is obtained in real time.

[0110] In another possible implementation, the computer device obtains the remaining amount of materials of the material-using party based on the amount of materials used by the material-using party and the total amount of materials stored in the automatic guided vehicle, in combination with the production volume of the products of the material-using party. Optionally, the computer device determines the absolute value of the difference between the amount of materials used by the material-using party and the total amount of materials stored in the automatic guided vehicle as the remaining amount of stored materials; further, obtains the production volume of the products of the material-using party within the first time period; then, based on the production volume of the products of the material-using party, determines the actual amount of materials used by the material-using party, where the actual amount of materials used by the material-using party refers to the weight of the materials actually used when producing products; then, determines the absolute value of the difference between the amount of materials used by the material-using party and the actual amount of materials used by the material-using party as the remaining amount of used materials; then, determines the sum of the remaining amount of stored materials and the remaining amount of used materials as the remaining amount of materials of the material-using party.

[0111] In summary, in the technical solution provided by the embodiment of the present application, the remaining amount of materials is obtained through the amount of materials used by the material-using party and the total amount of materials stored in the automatic guided vehicle, and the usage situation of the materials during the product production process is detected, which is convenient for timely replenishing the materials when the remaining amount of materials cannot meet the production requirements; moreover, when obtaining the remaining amount of materials, on the one hand, the remaining amount of stored materials remaining in the automatic guided vehicle is considered, and on the other hand, the remaining amount of used materials remaining during the product production is considered, and the final remaining amount of materials is obtained based on the remaining amount of stored materials and the remaining amount of used materials, improving the accuracy of obtaining the remaining amount of materials, and further improving the accuracy and timeliness of the material replenishment request.

[0112] Please refer to Figure 4 , which shows the flowchart of the material management method provided by another embodiment of the present application. This method is applied to Figure 1 the server in the material regulation system 11 shown in, and can also be applied to the material management service section in the automatic guided vehicle (collectively referred to as "computer device" hereinafter). This method may include the following steps (401~407):

[0113] Step 401, obtain the remaining amount of materials of the material-using party.

[0114] Step 402, generate a material replenishment request when the remaining amount of materials of the material-using party cannot meet the production requirements.

[0115] Step 403, based on the material replenishment request, control the automatic guided vehicle to move to the material replenishment area.

[0116] The above steps 401~403 are similar to Figure 3 the steps 301~303 in the Figure 3 embodiment. For details, please refer to the

[0117] Step 404: In response to a material storage request, obtain the identity information of the material provider.

[0118] The material storage request is used to request storing materials in the storage cabinet of the automatic guided vehicle. The material provider is the user who puts the materials into the storage cabinet. Exemplarily, the material provider is a warehouse administrator. Herein, the material provider and the above-mentioned material user can be the same or different. Optionally, there is a material storage button on the automatic guided vehicle. When the automatic guided vehicle detects a trigger operation on the material storage button, a material storage request is generated, and then the computer device obtains the identity information of the material provider in response to the material storage request. Herein, the above-mentioned trigger operation can be a long press operation, a short press operation, a swipe operation, etc., and the embodiments of the present application do not limit this. Optionally, the above-mentioned material provider can also be referred to as a replenishment provider.

[0119] In a possible implementation manner, since the automatic guided vehicle can also perform material recycling and material retrieval, different buttons correspond to different operations on the materials; that is, there is also a material recycling button for triggering the material recycling operation and a material retrieval button for triggering the material retrieval operation on the automatic guided vehicle. In this case, the touch operations for different buttons can be the same or different.

[0120] In another possible implementation manner, the above-mentioned material storage button can also be referred to as a material recycling button and a material retrieval button, and different requests are generated through different touch operations on the same button. In this case, different requests correspond to different touch operations.

[0121] Optionally, the automatic guided vehicle has an information scanning section, and the computer device obtains the identity information of the material provider through the information scanning section. Exemplarily, the material replenishment request includes the identity information of the material provider, and after detecting the material replenishment request, the computer device obtains the identity information of the material provider from the material replenishment request.

[0122] Step 405: When it is determined based on the identity information of the material provider that the material provider has the material storage permission, open the storage cabinet of the automatic guided vehicle.

[0123] In the embodiments of the present application, after obtaining the identity information of the material provider, the computer device identifies the permission of the material provider based on the identity information, and when it is determined that the material provider has the material storage permission, opens the storage cabinet of the automatic guided vehicle. Optionally, if there are multiple idle storage cabinets in the automatic guided vehicle, randomly open one or more storage cabinets for subsequent material replenishment.

[0124] Step 406: When the material storage is completed, update the material storage information based on the material storage request through the weighing sensor in the storage cabinet.

[0125] In the embodiment of the present application, after the material storage is completed, the storage cabinet is closed by the material feeder. At the same time, when the computer device determines that the storage cabinet is closed, it determines that the material storage is completed, and then updates the material storage information based on the weighing sensor in the storage cabinet and the material storage request. The material storage information is used to record the correspondence between the identity information and the stored material information, and the material information includes the material weight.

[0126] Optionally, the above-mentioned material information further includes but is not limited to at least one of the following: material ID, material model, material batch, etc. Optionally, the above information scanning section can also obtain associated material information when storing materials, and the associated material information includes but is not limited to at least one of the following: material ID, material model, material batch, etc.

[0127] Step 407, when it is determined that the material replenishment based on identity recognition is completed, control the automatic guided vehicle to move to the material retrieval area.

[0128] The above step 407 is similar to Figure 3 step 304 in the Figure 3 embodiment. For details, please refer to the

[0129] embodiment and will not be elaborated here.

[0130] Optionally, the correspondence between the identity information and the permissions of each user can be pre-stored in the computer device. After obtaining the identity information, the computer device determines the permissions of the user indicated by the identity information based on the pre-stored correspondence, and then completes the permission determination.

[0131] In summary, in the technical solution provided by the embodiment of the present application, different permissions are set for different users. When replenishing materials, it is determined whether the replenishing party has the material replenishment permission through identity recognition. Then, when the replenishing party has the material replenishment permission, the storage cabinet is opened to enable the replenishing party to replenish materials, and the replenishment of materials is reasonably controlled by the automatic guided vehicle, reducing the replenishment chaos caused by manual operation.

[0132] In addition, the automatic guided transport vehicle equipped with storage cabinets can realize material replenishment and storage as well as material recovery and retrieval. That is, the automatic guided transport vehicle can detect the entire process of materials from the warehouse to the production line, which is convenient for material management and control and reduces the confusion caused by manual management of material use processes. Moreover, before performing various operations on materials, identity recognition is performed based on identity information to determine the corresponding authority, and whether the user can perform the corresponding operation on the material is determined based on the identity authority, thereby improving the safety of the overall process of materials from the warehouse to the production line and facilitating the fully automated material management of precious materials, hazardous materials, etc.
