Detailed Description

In fig. 1-4, the system provided by the invention ensures the accuracy and real-time performance of the material frame tracking process, and has the advantages of simple implementation, low cost and the like. The technical scheme adopted by the invention is a forge piece material frame tracking management system in the production and manufacturing process, and the system is realized by the following steps:

the raw materials are firstly sent to a forging workshop for processing, after forging is completed, the batch of forgings are generated and transferred to a heat treatment workshop for task, binding information between the forgings and the forging workshop is generated, and scheduling time and single number information are recorded. The transfer transportation task comprises the total amount and weight of single-batch forge pieces, the batch number of the forge pieces, whether a single forge piece is a large one, a transportation starting point and a transportation end point, when the network server receives the transfer transportation task of the forging shop, the network server generates a transportation instruction aiming at the transfer transportation task, gives priority to the transportation instruction, obtains a material frame in an idle state between the vehicles according to the transportation instruction, and compares the load capacity limit of the transportation task and the material frame in the idle state between the vehicles.

When the total weight of a single batch of forgings in a forging workshop is larger than the load capacity limit of the material frames in the idle state in the workshop, the transportation efficiency of the batch of forgings is reduced, and at the moment, the network server sends a carrying instruction to other workshops and selects the material frames in the idle state in the other workshops. The network server selects idle state material frames of other workshops nearby according to the priority of the carrying instruction and transfers the idle state material frames to the forging workshop, and selects the heat treatment workshop with the shortest path from the forging workshop as much as possible to transfer.

Due to the fact that the total weight and the number of the forgings in different batches are different and the types of the forgings are different, the load capacity limits of material frames of different types are also different. When the single batch of forged pieces are large forged pieces, the network server generates a carrying instruction aiming at the large forged piece transfer and transportation task, gives priority to the carrying instruction, acquires the metal bar code of the large material frame in the idle state according to the carrying instruction, and compares the load capacity limit of the large material frame in the idle state between the large material frame and the large material frame. When the weight of a single batch of large-piece forgings is larger than the load capacity limit of the large-piece material frame in the idle state in the workshop, the network server sends a carrying instruction to other workshops at the moment, and the carrying instruction is selected from the large-piece material frames in the idle state in other workshops. The network server can reasonably distribute the material frames according to the carrying instructions with different priorities and preferentially select the large material frames of the nearby workshops for transfer.

When idle state material frames in other workshops are transferred to a forging workshop, scanning and uploading a network server at a material frame monitoring node No. 1 in the forging workshop, uploading a new identification entry to a database by the network server, writing in material frame binding forging workshop information, and recording scheduling time and single number information.
