Solution：

·Data collection

  Constrained data: production line capacity, shift number, personnel skills...

  Process data: BOM, process route, lead time, substitute resources, relationship between production line and product, relationship between production line and tooling, relationship between production line and mold

  Demand and supply data: order data, safety stock, current quantity of sub-stock;

  Resource state: production equipment state, tooling state, mold state, workers available state;

  Other data: work calendar, production batch.

· Production planning

  Get orders: get orders from ERP in a certain time range;

  Work list is formed: work list can be formed according to process route decomposition;

  Form the production plan: consider the possibility of capacity, personnel and materials, form the plan according to the ordering rules and optimization goals for each process;

  Restrictions: each machine is allowed to produce only one work piece at a time; The next process can only be arranged after the end of the process.

· Interface with each system in equipment and factory

  Connect directly to device (or SCADA);

  Interface data format tourmaline complies with standard specification;

  The device needs to be able to work offline (manual enforcement, data temporary storage).

· Device interface protocol

  State information, such as heartbeat, quality check, material status, etc.

  Collect abnormal information, equipment running record, equipment alarm record;

  Processing, waiting, idle time, etc.

  Processed quality information, on-site quality problem records, defect records, unqualified products records, on-site inspection records, finished product audit records;

  Product unique code, barcode tracing, basic product information, etc.

Production process data, production quality data, manufacturing defective products, shipping information, finished product inventory information, labor hours.

Faced with the characteristics of high complexity of mechanical processing, high requirements for informatization integration, high difficulty of equipment control and great risk, the informatization level of equipment, labor, logistics, intelligent workshop and other fields has been greatly improved through this round of informatization construction.

· It has successfully avoided the disadvantages of numerous information collection nodes and lack of unified management means and methods；

· Solve the problem of information concentration due to various equipment models and brands;

· Adopt hard and soft dual engine to completely solve the contradiction between industrial control protocol and IT protocol conversion;

· Through the platform construction, the limitation of the original platform information degree is broken through, and the full interconnection is realized.
