Research On The Key Technology Of Workshop Logistics System For Mold Production Automation

At the age of "Industry 4.0", the automation of mould processing has become the major development trend for future Mould technology. As the component of mould processing, logistics automation of mold workshop is an important aspect of the future mould industry. Real-time information acquisition in the mould workshop site during the logistics process is the key to realize the logistics automation. In this paper, we introduce RFID(Radio Frequency IDentification) into the mould production process combining with the characteristics of mould workshop logistics. We focus on automatic acquisition and processing of logistics information. And we also investigate the key technology to implement the mould workshop logistics system based on RFID.First, we determine the characteristics of logistics information and requirements by analyze the processing. Combined the technology of Internet of Things, a Mould Enterprise Logistics Management construction can be built. On the base, we propose an event-handling mechanism during logistics transportation process based on RFID. By filtering and packaging mass label incidents in logistics process, along with handling and integrating critical business events, it can be converted into monitoring events which the mould industries care about mostly. Based on the event information handling above, effective transformation and rapid transmission of various information in the logistics processing can be realized.Then, logistics car scheduling mechanism is proposed aiming at the features of mould workshop tasks formation. Via task assigning policy, the logistics tasks can be distributed to logistics car in time. On the premise of voiding jam, the car logistics route planning task can be completed. In the logistics mission, congestion conflict can be real time monitored. Once happened, congestion avoidance strategy will come into effect.Last, on the basis of the investigate above, uniting the B/S and C/S mixed development mode, mould workshop logistics system based on RFID is exploited which realizes real- time acquisition of processing information, real- time scheduling of logistics resource and real- time monitoring of the processing. This lays a good foundation to promote the automation of mould processing.
