[0117] In order to better understand the above-mentioned device, the following will be described in combination with another embodiment, in which, by constructing an "ERP-MES multi-protocol equipment" full data closed loop system, the industry pain points of photovoltaic adhesive film return material full process traceability, unstable equipment data acquisition under high temperature process, ERP and MES data synchronization lag, return material addition ratio out of control and poor networking adaptability of multi-protocol equipment are solved, and the full process digital control from raw material procurement, formula mixing, flow forming, return material reuse to finished product delivery is filled, and the technical blank of "system integration + return material traceability + equipment networking" is filled in the photovoltaic adhesive film industry.

[0118] Optionally, in the embodiment, the ERP layer includes sales order, BOM, procurement to arrival, quality inspection, warehouse in / out modules;

[0119] MES layer: production plan, workshop order, work order, material feeding and reporting, accounting module;

[0120] Equipment networking layer: network port equipment, serial port equipment (through serial port server), wireless equipment (through wireless transceiver terminal), multi-protocol intelligent gateway;

[0121] Data interaction layer: bidirectional real-time synchronization engine, multi-protocol dynamic conversion module, edge intelligent analysis unit.

[0122] System initialization and data synchronization process: the ERP synchronizes the photovoltaic adhesive film special BOM (EVA / POE formula data), sales order and return material batch information to the MES through the bidirectional real-time synchronization engine, and the MES automatically generates the production plan, workshop order and work order, and associates the flow forming process parameter standard (such as temperature 70-80℃, extrusion speed threshold);

[0123] The return material generates a special batch barcode after being crushed, and the original production order full link information (including raw material batch, flow forming process, quality inspection result) is bound and synchronized to the MES return material management module and the ERP return material batch management module;

[0124] The flow forming machine, extruder and other equipment automatically identify the communication protocol through the multi-protocol intelligent gateway, and the equipment basic parameters (rated temperature, capacity) are synchronized to the MES equipment management module, supporting the "hot plug" access of new equipment.

[0125] Production execution and equipment data acquisition process: the MES assigns the work order to the corresponding production line, automatically issues the formula mixing ratio (including return material addition ratio) and flow forming process parameters, and when the equipment is running, the high temperature environment data acquisition module collects the running state (duty ratio, fault code) and process parameters (adhesive film thickness, extrusion speed) of the flow forming machine under 80℃ working condition in real time, and transmits them to the MES through the multi-protocol gateway, and dynamically updates the work order progress;

[0126] When the returned material is put into production, the returned material batch code is read through the serial port server, the MES returned material traceability engine automatically associates the original order and the quality inspection result, and the proportion of returned material is monitored in real time. When the proportion exceeds the threshold, an audible and light warning is triggered.

[0127] After the raw material is stored and the inspection is qualified, the ERP quality inspection data is pushed to the MES through the interactive engine, and the corresponding work order demand is automatically bound. After the finished product inspection data is input into the MES, it is real-time returned to the ERP, and the finished product code is generated (associated with the raw material batch, the returned material proportion, and the process parameters).

[0128] Data closed loop and protocol adaptation process: after the work order is reported, the MES accounting data is synchronized to the ERP, and the delivery progress of the sales order is updated; the four-level traceability of "raw material batch-returned material batch-work order-finished product code" is realized, and the customer can directly check the returned material original order and the whole process data by scanning the finished product code;

[0129] The system has a built-in photovoltaic adhesive film special traceability algorithm, which can reversely trace the key data such as the casting temperature curve and the equipment utilization rate when the returned material is first produced, providing complete basis for quality analysis.

[0130] Abnormal processing and intelligent analysis process: if the equipment fails or the data is abnormal, the abnormal warning module will immediately trigger an audible and light alarm, and the MES can adjust the production plan and update the delivery expectation to the ERP;

[0131] The system has built-in process warning models for adhesive film thickness deviation and crosslinking degree anomaly, which can predict quality risks based on real-time data and provide adjustment suggestions in advance.
