In other words, the user can perform data compression and memory operation through the advanced programming and scheduling system and/or the memory (storage device) of the manufacturing execution system to reduce the access to the database and the server, thereby achieving the decentralized manufacturing scenario/system, and the dispatch system 100 can update the field table or the state table of the object data according to the operation result to output the input data.

In this embodiment, the dispatch system 100 may be provided in a workstation or a storage device of a manufacturing scene, for example, for user operation. The workstation may be used to control a plurality of process equipment and the plurality of workstations may achieve a production goal. Alternatively, the dispatch system 100 may be, for example, disposed in a cloud server for user operation, and connected to a control workstation and output the computed field table and data. In this embodiment, the storage device 110 may include a Memory (Memory) and/or a database (database), wherein the Memory may be, for example, a Non-Volatile Memory (NVM). The storage device 110 may store relevant programs, modules, systems, or algorithms for implementing embodiments of the invention for access and execution by the processor 111 to implement the relevant functions and operations described by embodiments of the invention.

FIG. 3 is a schematic diagram illustrating the implementation of the data conversion and operation specifications according to an embodiment of the present invention. Reference is made to fig. 1 and 3. In this embodiment, the data conversion module 112 stores the object data in the plurality of data set areas 350 according to the service type of the initial service data. The service category may be work order group data, device group data, and route group data. That is, the data conversion module 112 stores the corresponding object data in different memory blocks of the storage device 300 according to the type and the feature content of the initial service data. In this embodiment, the algorithm is a logic rule Specification (Specification), which relates to related logic in the manufacturing site.

TABLE 3 Table 3

Reference is made to fig. 1 and 4. In the present embodiment, the data mapping units 411 and 425 create a plurality of object set blocks (422, 423 and 424) in the storage device 110, and store the objects with the same bit states in the same object set blocks according to the index mode to compress the stored data. The processor 420 reads corresponding object data from different object set blocks through the data mapping unit 425, and performs operations in the processing logic 426 (operation specification). Thus, the processor 420 can process only part of the object data corresponding to the operation specification, thereby simplifying the operation and loading of the data volume for use and access to improve the overall efficiency. In this embodiment, the memory manager 410 accesses the corresponding object data from the corresponding service types (412, 413) through the data mapping unit 411, so as to generate the shared data (step S415). The transmission module 414 may output the shared data as output data 416 to an external dispatch system or other storage device of the dispatch system of the present invention. In the present embodiment, the shared data is a corresponding portion accessed from the object data by the data mapping unit 411. Thus, the transmission module 414 can only transmit the changed corresponding part of the object data after operation, so as to greatly reduce the data transmission amount in the manufacturing scene and reduce the access of the dispatch system to the server and the database, thereby improving the data transmission efficiency.

FIG. 5 is a diagram illustrating performing data compression and updating a field table according to an embodiment of the present invention. Reference is made to fig. 1 and 5. In step S511, the dispatch system 100 based on the memory operation loads the initial business data from the enterprise resource planning (Enterprise resource planning, ERP) system 510 into the memory 520 of the dispatch system 100, and the storage format is the memory address format. The memory 520 stores field tables 531 and 541 corresponding to the initial service data. In step S512, the processor 111 stores the object data in different memory blocks according to the data status, and the memory block address may be provided by the pointer. In the present embodiment, the processor 111 performs bit operation on the object data, and transfers the data state and the stored memory block according to the operation result. It should be noted that, the processor 111 updates the field table after operation by the operation module 113. That is, the field table stored in the memory 520 generates the updated field table 542 according to the operation result. In this embodiment, the dispatch system 100 may receive updated field tables 532 and 533 from other dispatch systems or storage devices, and further update the field tables or object data in the memory 520 accordingly.

FIG. 6 is a schematic diagram of performing sharing of data according to an embodiment of the present invention. Refer to fig. 6. In this embodiment, the dispatch system 600 based on memory operations of the present invention may include a manufacturing execution system 610 and an advanced planning and scheduling system 620, and the manufacturing execution system 610 and the advanced planning and scheduling system 620 may each include a storage device capable of performing memory operations. In step S621, the processor reads data. The data may be business data or related data and indications in a manufacturing scenario. The processor may read and access the service data stored in the memory device or load the service data from the database. In step S622, the processor generates a corresponding data block in the memory (storage device) according to the data. The processor generates corresponding data blocks according to the service type of the service data and/or the status value of the service data so as to achieve data compression. In step S623, the processor generates a corresponding data block in the buffer block 627 according to the data. In this embodiment, the processor stores the object data in the buffer blocks 611 and 627 according to the frequency of use of the data. In this embodiment, the address is a hash value. In step S624, the processor extracts the corresponding data 631, 637, 612 from the hash values 633, 639, 636 by having a different hash value for each object data, as the shared data 630 or performs a bit operation.

Reference is made to fig. 1 and 6. In the present embodiment, the operation module 114 determines whether the data to be extracted is stored in the buffer 611/627 of the storage device 110. When the extracted data is stored in the buffer 611/627, the operation module 114 outputs the extracted data from the buffer 611/627 to the data exchange area according to the address. And when the extracted data is not stored in the buffer 611/627, the operation module 114 outputs the extracted data from the object set block to the data exchange area according to the address. In step S625, the operation of the data determines the state by bit operation. In step S626, the processor outputs corresponding data according to the hash value.

In this embodiment, the processor transfers object data 631, 637 corresponding to hash values 633, 639 into the shared data 630 region. Thus, the object data 632, 638 output by the advanced planning and scheduling system 620 can be accessed by the manufacturing execution system 610 to share the inter-working memory data and extract some of the required data in the business data. Thus, the manufacturing scenario using the dispatch system of the present invention can achieve reduced on-line complexity, improved efficiency in responding to client requirements, and decentralization to reduce server/database workload. In the invention, a system with the same core (kernel) architecture can achieve the sharing of intercommunication memory data. Therefore, the operation and calculation between each dispatching system and each manufacturing system in the manufacturing scene can be achieved only by transmitting the field table (data specification), so that the data transmission efficiency is improved.

In summary, the dispatch system and the dispatch method based on memory operation of the present invention can achieve that the data loading and output data specification between the systems are not related to the database in the manufacturing scene. Therefore, the loading and bridging of various production environments can achieve the benefits of sharing memory data and reducing the transmission data amount only by loading the data conversion specification and the loader, and the production efficiency and the instruction response efficiency of the workstation in the manufacturing scene are effectively improved.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and not for limiting the same; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some or all of the technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit of the invention.
