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.

[0013] 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.

[0014] Optionally, the material control system 11 and the material transportation system 12 are connected via a network.

[0015] 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 actual conditions. For example, the material control system 11 and the material transportation system 12 can be set in the same device, for example, a material management service module is set in an automatic guided transport vehicle to realize self-management of the automatic guided transport vehicle.

[0016] Please refer to Figure 3 , which shows a flow chart of a material management method provided by an embodiment of the present application. The method is applied to Figure 1 The server in the material control system 11 shown can also be applied to the material management service section in the automatic guided transport vehicle (hereinafter collectively referred to as "computer equipment"). The method may include the following steps (301-304): Step 301, obtaining the remaining amount of materials of the material user.

[0017] The material user is the material user, and the material user includes at least one material user, who can also be called a product production worker. 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 material refers to the weight of the material that has not been put into production.

[0018] In the embodiment of the present application, during the production process of the product, the computer device performs real-time detection of the material usage to obtain the remaining amount of the material of the material user. Optionally, the computer device performs real-time detection of the material usage with the material user as the minimum unit, obtains the remaining amount of the material of each material user, and then obtains the remaining amount of the material of the above-mentioned material user.

[0019] Step 302: When the remaining material quantity of the material user cannot meet the production demand, a material replenishment request is generated.

[0020] 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 obtaining the remaining amount of materials of the above-mentioned material user, the computer device 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.

[0021] Optionally, the computer device determines whether to generate a material replenishment request based on the material usage of the material user. In an exemplary embodiment, the above step 302 includes the following steps: 1. When the remaining material quantity of the material user cannot meet the production demand, obtain the identity information of the material user; 2. Based on the identity information of the material user, obtain the material usage of the material user; 3. When the material usage of the material user is less than the fourth threshold, a material replenishment request is generated.

[0022] The material usage of the material user refers to the total weight of the materials taken out by the material user through the storage cabinet of the automatic guided transport vehicle within the first time period. Among them, the first time period can be any time period, and the first time period can be flexibly set and adjusted according to the actual situation, and the embodiment of the present application does not limit this. 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 from a certain moment of the day to the current moment, and the certain moment can be any moment before the current moment; and so on.

[0023] The identity information of the material user is used to indicate the unique identity of the material user. In an embodiment of the present application, the computer device obtains the identity information of the material user when the remaining amount of materials of the material user cannot meet the production demand. Optionally, the computer device obtains the identity information of the material user through an image acquisition device and image detection technology (such as face recognition technology, work station recognition technology, etc.). It should be noted that, when the material user includes multiple material users, the identity information of the material user includes the identity information corresponding to each material user.

[0024] In an embodiment of the present application, after obtaining the identity information of the material user, the computer device obtains the material usage of the material user based on the identity information of the material user. Optionally, the computer device stores material removal information, which is used to record the correspondence between the identity information and the removed material information, and the material information includes the material weight. Optionally, after obtaining the identity information of the material user, the computer device obtains the material usage of the material user from the correspondence contained in the material removal information based on the identity information of the material user. Optionally, the above-mentioned material information also includes but is not limited to at least one of the following: material ID (Identity document), material model, material batch, etc.

[0025] 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.

[0026] 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.

[0027] Step 303: Based on the material replenishment request, control the automatic guided vehicle to move to the material replenishment area.

[0028] 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.

[0029] 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.

[0030] 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.

[0031] The material access area refers to the area where materials are accessed. For example, the material access area may be near a material user's workstation, near a production line that needs to use materials, or the central area of ​​multiple production lines that need to use materials. In the embodiment 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, it controls the automatic guided transport vehicle to move to the material access area.

[0032] The above-mentioned identity recognition is used to determine whether the party who replenishes the materials has the authority to replenish the materials. Optionally, since different users have different corresponding material authorities, after the automatic guided transport vehicle moves to the material replenishment area, it determines whether the party who replenishes the materials has the authority to replenish the materials based on identity recognition, and then, if the party who replenishes the materials has the authority to replenish the materials, the storage cabinet is opened to allow the party who replenishes the materials to replenish the materials. After that, after the storage cabinet is closed, it is determined that the material replenishment is completed, and then the computer device controls the automatic guided transport vehicle to move to the material access area. Optionally, the above-mentioned identity recognition includes but is not limited to at least one of the following: face recognition, fingerprint recognition, voice recognition, access card recognition, etc.

[0033] Optionally, the material replenishment request includes the identity information of the material user, and when the material replenishment is completed, the automatic guided transport vehicle is controlled to move to the material collection area corresponding to the material user.

[0034] To summarize, in the technical solution provided in the embodiment of the present application, by detecting the remaining material quantity of the material user, when the remaining material quantity cannot meet the production demand, a material replenishment request is generated to replenish the material, that is, when there is a surplus of material, the material is replenished in time in combination with the production demand, thereby reducing the decline in product output caused by the idle production line or workers during the replenishment process, and improving product production efficiency; moreover, by moving the automatic guided transport vehicle loaded with storage cabinets between the material replenishment area and the material access area to replenish materials, while saving human resources, identity recognition is introduced in the material replenishment process, and whether the user can replenish materials is determined based on identity permissions. The replenishment of materials is reasonably managed and controlled by the automatic guided transport vehicle, thereby improving the safety of the material replenishment process, reducing the confusion of replenishment caused by manual labor, and facilitating the automatic replenishment of precious materials, hazardous materials, etc.

[0035] In addition, since large material loss is often accompanied by large material usage, when it is determined that the remaining material cannot meet production needs, the material usage of the material user is obtained based on the identity information of the material user, and then a material replenishment request is generated when the material usage is less than the fourth threshold. While replenishing materials in a timely manner, the material usage is restricted, and the material user with excessive material usage can be detected in time, which makes it easier to conduct subsequent inspections on the material user, thereby reducing material waste from the side.

[0036] Next, the movement of automated guided transport is described in detail.

[0037] In an exemplary embodiment, the above step 303 includes the following steps: 1. Based on the material replenishment request, determine the identity information of the material user.

[0038] Optionally, the material replenishment request includes the identity information of the material user. In the embodiment of the present application, after obtaining the material replenishment request, the computer device determines the identity information included in the material replenishment request as the identity information of the material user.

[0039] 2. Based on the identity information of the material user, obtain the material loss of the material user.

[0040] The material loss amount of the material user refers to the total weight of 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 materials remaining on the surface of the container after the use of the materials. In an embodiment of the present application, after obtaining the identity information of the above-mentioned material user, the computer device obtains the material loss amount of the material user based on the identity information of the material user. Optionally, material recovery information is stored in the computer device, and the material recovery information is used to record the correspondence between the identity information and the recovered material information, and the material information includes the weight of the material. 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 contained in the material recovery information, the total weight of 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.

[0041] Optionally, the automatic guided transport vehicle has an information scanning section and a weighing sensor is provided in the storage cabinet. When recycling materials, the identity information of the material user is obtained through the information scanning section, and the weight of the recycled 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 recycling information through the acquired data. Optionally, the above-mentioned information scanning section can also obtain related material information when recycling materials, and the related 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.

[0042] 3. When the material loss of the material user is less than the first threshold, the automatic guided transport vehicle is controlled to move to the material replenishment area.

[0043] In the embodiment of the present application, after obtaining the material loss amount of the material user, the computer device compares the material loss amount of the material user with the first threshold value, and when the material loss amount of the material user is less than the first threshold value, based on the identity information of the material user, controls the automatic guided transport vehicle to move to the material replenishment area. The first threshold value can be any value, and the first threshold value can be flexibly set and adjusted according to actual conditions, and the embodiment of the present application does not limit this.

[0044] In one possible implementation, when the computer device determines that the material loss of the material user is less than a first threshold, the computer device controls the automatic guided transport vehicle to move to the material replenishment area. In another possible implementation, when the computer device determines that the material loss of the material user is less than a first threshold, the computer device determines whether to control the automatic guided transport vehicle to move to the material replenishment area according to the product production volume of the material user. The product production volume of the material user refers to the weight / quantity of products produced by the material user using the material. Optionally, a weighing sensor is provided 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 implementations, the computer device can also obtain the product production output of the material user in real time based on the image acquisition device and the image detection technology.

[0045] Optionally, when the computer device determines that the material loss of the material user is less than a first threshold, the computer device obtains the product production volume of the material user in a first time period based on the identity information of the material user; further, when the product production volume of the material user meets the conditions, the computer device controls the automatic guided transport vehicle to move to the material replenishment area based on the identity information of the material user.

[0046] In a possible implementation, the computer device directly determines whether it meets the conditions through product production. Optionally, after obtaining the product production of the material user, the computer device compares the product production with the fifth threshold; further, when the product production of the material user is greater than or equal to the fifth threshold, it is determined that the product production of the material user meets the conditions; conversely, when the product production of the material user is less than the fifth threshold, it is determined that the product production of the material user does not meet the conditions. The fifth threshold can be any value, and the fifth threshold can be flexibly set and adjusted according to actual conditions, and the embodiments of the present application do not limit this.

[0047] In another possible implementation, the computer device determines the material usage rate through the product production volume, and then determines whether the product production volume meets the conditions based on the material usage rate. Optionally, the computer device obtains the material usage of the material user based on the identity information of the material user. Exemplarily, the computer device obtains the material usage of the material user through the above-mentioned material removal information; then, the computer device determines the material usage rate of the material user based on the product production volume of the material user and the material usage of the material user; further, when the material usage 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 usage 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 an arbitrary value, and the fifth threshold can be flexibly set and adjusted according to actual conditions, and the embodiments of the present application do not limit this.

[0048] Alternatively, the material usage rate may also be referred to as material utilization rate, which is used to indicate the effective use of materials during use.

[0049] In one possible implementation, after obtaining the product production volume of the material user, the computer device obtains the actual material usage of the material user based on the product production volume of the material user; further, based on the ratio between the actual material usage of the material user and the material usage of the material user, the material usage rate of the material user is determined. Among them, the actual material usage is used to indicate the weight of the material put into production and the corresponding product is obtained from the taken out material. Taking silver paste as an example, the weight of the taken out silver paste (i.e., the material usage) is 1kg, and the weight of the silver product produced (i.e., the product production volume) is 0.99kg, then the corresponding actual silver paste usage (i.e., the actual material usage) is 0.99kg, and the silver paste usage rate (i.e., the material usage rate) is 99%.

[0050] In another possible implementation, after the computer device obtains the product production volume of the above-mentioned material user, it obtains the output prediction range of the material user based on the material usage of the material user; further, based on the relationship between the product production volume and the output prediction range of the material user, the material usage rate of the material user is determined. Taking silver paste as an example, the weight of the silver paste taken out (i.e., the material usage) is 1kg, and the corresponding silver product (or silver-containing product) prediction range (i.e., the output prediction range) is 0~100. If the number of silver products (or silver-containing products) produced (i.e., the product production volume) is 99, then the silver paste usage rate (i.e., material usage rate) is 99%.

[0051] Optionally, the above-mentioned silver product can be a product obtained by processing with silver paste as a single material; it can also be a product obtained by processing with 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 are not limited to this.

[0052] Optionally, when the product production volume does not meet the conditions, the computer device generates a second warning information, and the second warning information is used to indicate that there is waste of materials in the production process. Exemplarily, if the above-mentioned material user includes at least one material user, the computer device obtains the production data of each material user respectively when determining that the product production volume does not meet the production conditions, and then based on the production data of each material user, the material user whose production data is less than the sixth threshold is determined as the second excess user, and the second warning information is generated based on the identity information of the second excess user, and the second warning information includes the identity information of each second excess user. Optionally, the above-mentioned production data includes but is not limited to at least one of the following: product production output, material utilization rate. Among them, the above-mentioned sixth threshold can be any value, and the sixth threshold can be flexibly set and adjusted according to actual conditions, and the embodiment of the present application does not limit this.

[0053] Optionally, when the material loss of the material user is greater than or equal to a first threshold, the computer device generates a first warning message, wherein the first warning message is used to indicate that there is waste in the material recycling process.

[0054] Optionally, if the material user includes at least one material user, when the material loss of the material user is greater than the first threshold, the computer device obtains the material loss of each material user respectively; then based on the material loss of each material user, the material user whose material loss is greater than the second threshold is determined as the first excess user; then, based on the identity information of the first excess user, a first warning message is generated, and the first warning message includes the identity information of each first excess user. The second threshold can be any value, and the sixth threshold can be flexibly set and adjusted according to actual conditions, which is not limited in the present embodiment of the application.

[0055] To sum up, in the technical solution provided in the embodiment of the present application, when the material loss amount is less than the first threshold value, the automatic guided transport vehicle is controlled to move to the material replenishment area, and the material loss amount is used as a constraint condition before replenishment. It is possible to timely detect large material loss before replenishment, thereby improving the rigor of automatic replenishment operation and indirectly reducing material waste caused by irregular replenishment. Moreover, there is a corresponding relationship between the identity information and the material loss amount, and the material loss amount can be reasonably detected and controlled, which is conducive to solving the problem of chaotic material management.

[0056] In addition, when the material loss amount is greater than the first threshold, a first warning information is generated to prompt that materials are wasted in the recycling process, so as to facilitate the subsequent timely processing of the material waste in the recycling process based on the first warning information, thereby reducing the waste of materials in the recycling process; moreover, the first warning information is generated based on the identity information of the excess user, that is, the identity information of the excess user can be traced back and determined according to the first warning information, and the material waste situation is specific to the individual, which is convenient for the management and control of material loss.

[0057] In addition, when the material loss is less than the first threshold value, and further when the product production output meets the conditions, the automatic guided transport vehicle is controlled to move to the material replenishment area, and the replenishment operation is further constrained on the basis of the material loss and the product production output, so as to further improve the rigor of the automatic replenishment operation; moreover, using the material utilization rate to characterize the specific waste of materials in the production process can better control the material production process, and timely discover unreasonable material waste in the product production process before replenishment, so as to facilitate the subsequent adjustment of product production, thereby indirectly improving product productivity.

[0058] It should be noted that the above description of the movement of the automatic guided transport vehicle is only exemplary and explanatory, and the steps for obtaining the above material loss amount and the above product production amount can be flexibly set and adjusted according to actual conditions. For example, in another possible implementation, the above step 303 includes the following steps: 1. Determine the identity information of the material user based on the material replenishment request; 2. Based on the identity information of the material user, obtain the product production volume of the material user in the first time period; 3. When the product production volume of the material user meets the requirements, the automatic guided transport vehicle is controlled to move to the material replenishment area.

[0059] Optionally, the computer device determines the material usage rate through the product production volume, and then determines whether the product production volume meets the conditions based on the material usage rate. Optionally, the computer device obtains the material usage of the material user based on the identity information of the material user; then, the computer device determines the material usage rate of the material user based on the product production volume of the material user and the material usage of the material user; further, when the material usage 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 usage 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 information, and the second warning information is used to indicate that there is waste of materials in the production process.

[0060] Optionally, when the product production volume of the material user meets the conditions, the material loss of the material user is further obtained based on the identity information of the material user, and then when the material loss of the material user is less than the first threshold, the automatic guided transport vehicle is controlled to move to the material replenishment area. Optionally, when the material loss of the material user is greater than the first threshold, the computer device generates a first warning information. The first warning information is used to indicate that there is waste of materials in the recycling process.

[0061] It should be noted that the specific details not introduced in this example are referred to above and will not be repeated here.

[0062] Next, determine whether the remaining material quantity of the material user meets the production demand.

[0063] In an exemplary embodiment, the above step 302 further includes the following steps: 1. Obtain the material usage rate of the material user.

[0064] The material usage rate is used to indicate the consumption rate of the material within a unit time. The unit time can be any value, such as 0.01s, 0.1s, 1min, etc., and the embodiment of the present application does not limit this.

Optionally, the computer device obtains the real-time material usage of the material user based on the current moment, and updates the material usage rate of the material user in real time based on the real-time material usage of the material user to obtain the material usage efficiency of the material user. Among them, the real-time material usage of the material user refers to the total weight of materials taken out by the material user through the storage cabinet of the automatic guided transport vehicle within the first interval duration; the first interval duration is less than or equal to the duration indicated by the above-mentioned first time period, and the first interval duration can be any duration, such as 1s, 10min, 1 hour, 1 day, etc., which is not limited in this embodiment of the present application.

Optionally, the computer device obtains the real-time product production of the material user based on the current moment, and updates the material usage rate of the material user in real time based on the real-time product production of the material user to obtain the material usage efficiency of the material user.

Optionally, after obtaining the real-time product production of the above-mentioned material user, the computer device infers the corresponding actual material usage based on the real-time product production of the material user, and then determines the ratio between the actual material usage and the second interval duration as the material usage rate of the material user.

[0067] It should be noted that the first interval duration and the second interval duration are both greater than the unit duration.

[0068] 2. Based on the material usage rate of the material user, predict the amount of materials required by the material user in the second time period.

[0069] In the embodiment of the present application, after obtaining the material usage rate of the material user, the computer device predicts the material quantity required by the material user in the second time period based on the material usage rate of the material user. Optionally, the computer device determines the material quantity required by the material user as the product of the material usage rate of the material user and the duration indicated by the second time period.

[0070] 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 based on the time required for the automated guided vehicle to travel from the material access area to the material replenishment area, and then return from the material replenishment area to the material access area. Exemplarily, the material replenishment duration is the time required for the automated guided vehicle to travel from the material access area to the material replenishment area, and then return from the material replenishment area to the material access area. It should be noted that the starting point of the second time period is the current time.

[0071] 3. When the remaining material quantity of the material user is less than the material quantity required by the material user, it is determined that the remaining material quantity of the material user cannot meet the production demand.

[0072] In an embodiment of the present application, after obtaining the remaining material quantity of the material user and the required material quantity of the material user, the computer device compares the remaining material quantity of the material user and the required material quantity of the material user. When the remaining material quantity of the material user is less than or equal to the required material quantity of the material user, it is determined that the remaining material quantity of the material user cannot meet the production demand; conversely, when the remaining material quantity of the material user is greater than the required material quantity of the material user, it is determined that the remaining material quantity of the material user can meet the production demand.

[0073] To summarize, in the technical solution provided in the embodiment of the present application, the required material quantity is predicted by the material usage rate, and then when the remaining material quantity is less than the required material quantity, it is determined that the remaining material quantity cannot meet the production demand, and the material usage rate is obtained in real time, taking into account the changes in the material usage rate under different situations (such as time, environment, space, etc.), thereby improving the real-time and accuracy of the predicted required material quantity, and thus improving the timeliness and accuracy of subsequent material production requests; moreover, the duration indicated by the second time period is greater than or equal to the material replenishment duration of the automatic guided transport vehicle, thereby ensuring that there is still sufficient material for production when the material replenishment request is generated, reducing the decline in product output caused by the idle production line or workers during the replenishment process, thereby improving product production efficiency, and determining the duration indicated by the second time period based on the material replenishment duration is conducive to solving the problem of frequent material replenishment caused by the second time period being too short, and thus helping to solve the problem of excessive energy consumption of the automatic guided robot caused by frequent material replenishment.

[0074] Next, the specific method of obtaining the remaining material quantity of the material user is introduced.

[0075] In an exemplary embodiment, the above step 301 includes the following steps: 1. Obtain the material usage of the material user and the total amount of materials stored in the automated guided vehicle.

[0076] In an embodiment of the present application, the computer device obtains the material usage of the material user and the total amount of materials stored in the automatic guided transport vehicle before obtaining the remaining material amount of the material user.

[0077] Optionally, a weighing sensor is provided in the storage cabinet of the automatic guided transport vehicle, and the weight of the stored materials is recorded by the weighing sensor when the materials are stored. Correspondingly, the weight of the taken out materials can also be recorded by the weighing sensor when the materials are taken out.

[0078] Optionally, the weight data recorded by the weighing sensor is transmitted to the computer device in real time. In an exemplary embodiment, when obtaining the material usage of the material user, the computer device determines the total weight of the materials taken out by the material user through the storage cabinet of the automatic guided transport vehicle in the first time period 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 transport vehicle in the first time period as the total amount of materials stored by the automatic guided transport vehicle.

[0079] Optionally, the computer device stores material removal information, which is used to record the correspondence between the identity information and the removed material information, and the material information includes the material weight. Exemplarily, when the computer device obtains the material usage of the material user, it obtains the material usage of the material user from the correspondence contained in the material removal information based on the identity information of the material user.

[0080] Optionally, in order to reduce the load on the device, the computer device deletes the weight data transmitted by the weighing sensor before the first time period.

[0081] 2. Based on the material usage of the material user and the total amount of materials stored in the automated guided vehicle, obtain the remaining amount of materials of the material user.

[0082] In an embodiment of the present application, after obtaining the material usage of the material user and the total amount of materials stored in the above-mentioned automatic guided transport vehicle, the computer device obtains the remaining material of the material user based on the material usage of the material user and the total amount of materials stored in the automatic guided transport vehicle.

[0083] In a possible implementation, 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 automated guided transport vehicle as the remaining amount of materials of the material user. Optionally, when the material user takes out materials through the storage cabinet, the computer device determines that the material usage of the material user has changed, updates the material usage of the material user in real time, and further, based on the updated material usage and the total amount of materials stored in the automated guided transport vehicle, obtains the remaining amount of materials of the material user in real time.

[0084] In another possible implementation, the computer device obtains the remaining amount of the material of the material user based on the material usage of the material user and the total amount of materials stored in the automatic guided transport vehicle, combined with the product production of the material user. Optionally, 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 transport vehicle as the remaining amount of stored materials; further, the product production of the material user in the first time period is obtained; then, based on the product production of the material user, the actual material usage of the material user is determined, and the actual material usage of the material user refers to the weight of the materials actually used when producing the product; then, the absolute value of the difference between the material usage of the material user and the actual material usage of the material user is determined as the remaining amount of used materials; then, the sum of the remaining amount of stored materials and the remaining amount of used materials is determined as the remaining amount of materials of the material user.

[0085] To summarize, in the technical solution provided in the embodiment of the present application, the remaining material amount is obtained by the material usage of the material user and the total amount of material stored in the automatic guided vehicle, and the material usage is detected during the product production process, so as to facilitate timely material replenishment when the remaining material amount cannot meet the production demand; moreover, when obtaining the remaining material amount, on the one hand, the remaining amount of stored material of the automatic guided vehicle is taken into account, and on the other hand, the remaining amount of used material during product production is taken into account, and the final remaining material amount is obtained based on the remaining amount of stored material and the remaining amount of used material, which improves the accuracy of obtaining the remaining material amount, and thereby improves the accuracy and timeliness of material replenishment requests.

[0086] Please refer to Figure 4 , which shows a flow chart of a material management method provided by another embodiment of the present application. The method is applied to Figure 1 The server in the material control system 11 shown can also be applied to the material management service section in the automatic guided transport vehicle (hereinafter collectively referred to as "computer equipment"). The method may include the following steps (401-407): Step 401, obtaining the remaining amount of materials of the material user.

[0087] Step 402: When the remaining material quantity of the material user cannot meet the production demand, a material replenishment request is generated.

[0088] Step 403: Based on the material replenishment request, control the automatic guided transport vehicle to move to the material replenishment area.

[0089] The above steps 401 to 403 are Figure 3 Steps 301 to 303 in the embodiment are similar, see Figure 3 The embodiments are not described in detail here.

[0090] Step 404, in response to the material storage request, obtain the identity information of the material discharger.

[0091] The material deposit request is used to request that materials be deposited into the storage cabinet of the automated guided transport vehicle. The material discharger is the user who places the materials into the storage cabinet. Exemplarily, the material discharger is a warehouse manager. The material discharger may be the same as or different from the material user. Optionally, there is a material deposit button on the automated guided transport vehicle. When the automated guided transport vehicle detects a trigger operation for the material deposit button, a material deposit request is generated, and then the computer device responds to the material deposit request to obtain the identity information of the material discharger. The trigger operation may be a long press operation, a short press operation, a sliding operation, etc., which is not limited in the embodiments of the present application. Optionally, the material discharger may also be referred to as a material replenishment party.

[0092] In a possible implementation, since the automated guided transport vehicle can also perform material recovery and material removal, different buttons correspond to different material operations; that is, the automated guided transport vehicle also has a material recovery button for triggering a material recovery operation and a material removal button for triggering a material removal operation. In this case, the touch operations for different buttons can be the same or different.

[0093] In another possible implementation, the material storage button may also be called a material recovery button or a material removal button, and different requests may be generated by performing different touch operations on the same button. In this case, different requests may correspond to different touch operations.

[0094] Optionally, the automated guided transport vehicle has an information scanning section, and the computer device obtains the identity information of the material discharger through the information scanning section. Exemplarily, the material replenishment request includes the identity information of the material discharger, and after detecting the material replenishment request, the computer device obtains the identity information of the material discharger from the material replenishment request.

[0095] Step 405, when it is determined based on the identity information of the material unloading party that the material unloading party has the material storage authority, the storage cabinet of the automatic guided transport vehicle is opened.

[0096] In the embodiment of the present application, after obtaining the identity information of the material discharger, the computer device identifies the authority of the material discharger based on the identity information, and opens the storage cabinet of the automatic guided transport vehicle when it is determined that the material discharger has the material storage authority. Optionally, if there are multiple idle storage cabinets in the automatic guided transport vehicle, one or more storage cabinets are randomly opened for subsequent material replenishment.

[0097] Step 406: When the material storage is completed, the material storage information is updated based on the material storage request through the weighing sensor in the storage cabinet.

[0098] In the embodiment of the present application, after the material storage is completed, the material discharging party closes the storage cabinet, and 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 corresponding relationship between the identity information and the stored material information, and the material information includes the material weight.

[0099] Optionally, the material information also includes but is not limited to at least one of the following: material ID, material model, material batch, etc. Optionally, the information scanning section can also obtain related material information when storing materials, and the related material information includes but is not limited to at least one of the following: material ID, material model, material batch, etc.

[0100] Step 407, 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 access area.

[0101] The above step 407 and Figure 3 Step 304 in the embodiment is similar, see Figure 3 The embodiments are not described in detail here.

[0102] One thing that needs to be explained is that in the embodiment of the present application, identity recognition does not only exist in material replenishment and material storage. When materials are recycled and taken out, identity recognition can also be used to determine material recycling and material replenishment for the automatic guided transport vehicle. Exemplarily, the computer device responds to a material take-out request, and when it is determined that the material take-out party has the authority to take out the materials, the computer device updates the material take-out information based on the material take-out request through the weighing sensor in the storage cabinet; similarly, the computer device responds to a material recovery request, and when it is determined that the recovery party has the authority to recover the materials, the computer device updates the material recovery information based on the material recovery request through the weighing sensor in the storage cabinet.

[0103] Optionally, the correspondence between the identity information and permissions of each user may be pre-stored in the computer device. After acquiring the identity information, the computer device determines the permissions of the user indicated by the identity information based on the pre-stored correspondence, thereby completing the permission determination.

[0104] To sum up, in the technical solution provided in the embodiment of the present application, different permissions are set for different users. When replenishing materials, identity recognition is used to determine whether the replenishing party has the material replenishment permission. Then, if the replenishing party has the material replenishment permission, the storage cabinet is opened to allow the replenishing party to replenish the materials. The replenishment of materials is reasonably managed and controlled through automatically guided transport vehicles to reduce the confusion of replenishment caused by manual labor.

[0105] 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.
