[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] At present, in the process of producing raw materials for lithium batteries, material preparation requires manual addition of raw materials for processing and manual recording. Each time material preparation is performed, a detailed material preparation form needs to be printed, and the actual weight of the material delivered by the RGV trolley needs to be observed and recorded in the form. Finally, it is recorded in the MOM system. However, this technical solution currently has the defects of consuming manpower and paper resources, and cannot be automated. In order to solve the above technical problems, the present application discloses a material preparation method, device, equipment and storage medium, which can be automatically operated in the entire material preparation process to reduce manual participation.

[0039] See also Figure 1 As shown, an embodiment of the present invention discloses a material preparation method, comprising:

[0040] Step S11, when the production system detects that the inventory material quantity is insufficient, the production system generates a corresponding material requirement list according to the inventory material quantity, and sends the material preparation request and the material requirement list to the warehouse management system, so that the warehouse management system sends the material requirement list to the manufacturing operation management system.

[0041] In this embodiment, according to Figure 1 In the material preparation process, the staff initiates a material preparation request from the production system. The production system first checks the inventory material quantity and receives the inspection quantity fed back by the inventory. When the production system detects that the inventory material quantity is insufficient, the production system generates a corresponding material demand list based on the inventory material quantity, and then sends the material preparation request and the material demand list to the warehouse management system (WMS). After receiving the request, the WMS system feeds back the material preparation detail data to the MOM system, that is, the warehouse management system sends the material demand list to the manufacturing operation management system. It should be pointed out that the warehouse management system is a real-time computer software system that can manage information, resources, behaviors, inventory and distribution operations more perfectly and improve efficiency according to the business rules and operation rules of the operation. Manufacturing operation management is the activity of converting raw materials or parts into products by coordinating and managing the resources such as personnel, equipment, materials, and energy of the enterprise. It includes the management of behaviors performed by physical equipment, people and information systems, and covers the management of activities related to scheduling, production capacity, product definition, historical information, production equipment information, and related resource status information.

[0042] Step S12: When the status of the material tank is idle or in operation, material preparation is started through the manufacturing operation management system, and the pallet code corresponding to the rail-guided vehicle that transports the material is sent to the distributed control system based on the material demand list, so that the distributed control system can compare the target pallet code scanned by the barcode scanner with the pallet code.

[0043] In this embodiment, after the WMS feeds back the material preparation details to the MOM, the manufacturing operation management system polls the material demand list to clarify the materials that need to be transported. When the status of the material tank is idle (301) or running (302), the MOM system will issue a start command "1" to the DCS (Distributed Control System), and issue a start command to the distributed control system through the manufacturing operation management system so that the distributed control system starts material preparation according to the start command. In this process, the point changes of the distributed control system are scanned regularly at a preset time, and the status of the material tank is determined based on the point changes. Specifically, a scheduled task is used to scan the point changes of the underlying DCS once every 3 seconds, and the status of the material tank is determined based on the point changes. After that, the start command is connected to the pallet code corresponding to the rail-guided vehicle that transports the material using the target symbol, and the corresponding connected information is sent to the distributed control system based on the material demand list. That is to say, when starting the material preparation, the MOM issues the pallet code of the planned material preparation to the DCS, and uses "#" to separate the start command and the pallet code to make the command information clearer. And the information after the start command is connected with the pallet code corresponding to the rail-guided vehicle that transports the materials is transmitted in units of one material tank, that is, different information will be transmitted according to the situation of each material tank.

[0044] When the DCS receives the pallet code and the target pallet code scanned by the device's built-in barcode scanner, it will compare the target pallet code scanned by the barcode scanner with the pallet code. Based on this judgment result, it is determined whether the rail-guided vehicle that transports the material has run into the wrong material tank, that is, whether the material is transported incorrectly. This ensures the accuracy of material transportation and input. If the comparison between the target pallet code and the pallet code is unsuccessful, the material transportation error is determined, and the corresponding alarm information is sent so that the staff can perform corresponding inspection operations based on the alarm information. At this time, the staff will need to intervene to determine which process has a problem and solve it in time.

[0045] Step S13: If the comparison is successful, the feeding state is changed to the running state through the distributed control system, and the planned weight corresponding to the pallet code is read through the manufacturing operation management system, and the planned weight is sent to the distributed control system, so that the distributed control system changes the running state to the ready state after receiving the planned weight.

[0046] In this embodiment, if the comparison between the target pallet code and the pallet code is successful, the DCS changes the feeding status to running (302). The MOM starts to read the pallet code that needs to be prepared, and sends the planned weight corresponding to the pallet code to the DCS, that is, the feeding status is changed to the running status through the distributed control system, and the planned weight corresponding to the pallet code is read through the manufacturing operation management system. Then, after receiving the planned weight, the DCS changes the running status to the ready status (303).

[0047] Step S14: clearing the planned weight value corresponding to the pallet code according to the ready state through the manufacturing operation management system, and putting the transported material into the material tank to complete material preparation.

[0048] In this embodiment, after receiving the 303 signal, the MOM will clear the value of the planned weight corresponding to the pallet code. Then the transported material can be put into the material tank to complete the material preparation. After the transported material is put into the material tank, the distributed control system changes the ready state to the end state, and updates the system material quantity according to the pallet code and the weight of the input material corresponding to the pallet code through the manufacturing operation management system. That is, when the feeding is completed, the state value of the feeding state becomes the 313 end state. At this time, the MOM system obtains the pallet code and the corresponding actual material quantity, and automatically updates the material quantity in the MOM system, thus completing the feeding process of one pallet. Repeat the above process to complete the automatic operation of all materials.

[0049] In summary, when the present application is preparing materials, when the production system detects that the inventory material quantity is insufficient, the production system generates a corresponding material requirement list according to the inventory material quantity, and sends the material preparation request and the material requirement list to the warehouse management system, so that the warehouse management system sends the material requirement list to the manufacturing operation management system; when the status of the material tank is idle or in operation, the material preparation is started through the manufacturing operation management system, and based on the material requirement list, the pallet code corresponding to the rail-guided vehicle that transports the material is sent to the distributed control system, so that the distributed control system compares the target pallet code scanned by the barcode scanner with the pallet code; if the comparison is successful, the feeding status is modified to the running status through the distributed control system, and the planned weight corresponding to the pallet code is read through the manufacturing operation management system, and the planned weight is sent to the distributed control system, so that the distributed control system modifies the running status to the ready status after receiving the planned weight; finally, the value of the planned weight corresponding to the pallet code is cleared through the manufacturing operation management system according to the ready status, and the transported material is put into the material tank to complete the material preparation. It can be seen that this application realizes automatic feeding by coordinating the production system, warehouse management system, manufacturing operation management system and distributed control system, performing different operations according to different signals. In this way, the entire material preparation process is automated, reducing manual participation, and no manual operation and information recording are required, so that the entire material preparation process can be completed automatically.

[0050] Based on the above embodiment, it can be known that the present application discloses an automated material preparation method, which can realize the automation of the entire material preparation process. Next, a detailed description will be given of the situation in which the material preparation process needs to be terminated.

[0051] like Figure 3 As shown, during the material preparation process, if the staff sends an instruction to terminate the material preparation to the production subsystem, the production subsystem sends a termination notice to the distributed control system so that the distributed control system controls the rail-guided vehicle to stop transporting materials, and returns the materials that have not been put into the material tank, and collects data statistics for the materials that have been put into the material tank. In this process, the production subsystem notifies the DCS through the inventory subsystem that the material preparation needs to be terminated, and the DCS sends a termination signal to the rail-guided vehicle that transports the material, and then the rail-guided vehicle stops transporting according to the termination signal and feeds back the corresponding termination signal. Then the DCS will feed back a termination signal to the inventory subsystem, and finally, return the materials that have not been put into the material tank, and collect data statistics for the materials that have been put into the material tank through the inventory subsystem. The operation of terminating the material preparation is now completed.

[0052] In this way, this application can not only automatically prepare materials under normal circumstances, but also respond in an orderly manner when there is an emergency that requires the termination of material preparation. There will be no system confusion, which ensures the accuracy of the material feeding and preparation process, and strictly follows the instructions to achieve orderly automation.
