Intelligent management method and system based on TPU plastic film production Technical Field The application relates to the field of plastic production technology, in particular to an intelligent management method and system based on TPU plastic film production. Background Thermoplastic polyurethane elastomer (TPU) films are widely used in the fields of clothing, shoe materials, medical treatment, automotive interiors, and the like, due to their excellent mechanical properties, abrasion resistance, and environmental protection characteristics. In the large-scale production of TPU films, in order to ensure the continuity and efficiency of production, a centralized feeding system is generally adopted to perform unified management and transportation of raw materials for a plurality of production devices. The existing centralized feeding system is generally composed of a central large storage bin, a plurality of hoppers, conveying pipelines and a central controller, wherein the basic feeding logic is that when the hopper of one production device detects that the raw material is lower than a set low position, a material shortage request signal is sent to the central controller, after the central controller receives the signal, the central controller controls to start a valve on the corresponding pipeline of the production device or start a corresponding conveying fan to convey the raw material from the central large storage bin to the hopper of the production device, and when the plurality of production devices send material shortage requests successively, the system is generally sequentially queued for feeding according to the receiving time sequence of the request signal. In the above related art, when a plurality of material shortage request signals are highly concentrated during the production peak period, the production equipment ordered later often needs to undergo a long waiting time to obtain raw material replenishment, and because the raw material buffer capacity of the equipment hopper is limited in the TPU film production process, if the waiting time is too long, the equipment is extremely easy to be forced to stop due to raw material exhaustion. Once the shutdown occurs, the current film production can be interrupted, a large amount of transition materials and waste products are generated, the subsequent procedures are disturbed, the restarting and debugging cost of equipment is increased, the continuity, stability and overall production efficiency of TPU film production are seriously affected, the overall production effect is poor, and the improvement space is provided.
