The control system involves stackers, automatic shuttles, automatic conveying equipment, palletizing robots, automatic guided vehicles (AGV) and other equipment. It is the control core of the entire automated warehouse system equipment execution. It is connected to the dispatching computer of the logistics system and accepts Material conveying instructions; connect the conveying equipment downward to realize the driving of the bottom conveying equipment and the detection and identification of conveyed materials; complete the transmission of material conveying and process control information. Realize the integrated control and management of equipment monitoring, data acquisition, communication network and control interface. Three levels of online, local and manual control are carried out through the touch screen or key switch. The system has strong scalability and compatibility, independent network design, and realizes a "distributed control and centralized management" structure with industrial Ethernet and fieldbus technology. The OPC protocol is used to communicate with WMS and ECS, and the RPOF IBUS field bus network formed by the SIEMENS S7-300 controller is mainly used to realize the graphical management of the equipment, integrate the video monitoring system, monitor the global operation in real time, and dynamically display the operation status and location of the equipment , Fault alarm, etc., and provide manual intervention functions to develop mobile terminal alarm services. Realize management task decomposition and path optimization, and send it to the equipment control system through PROFINET industrial Ethernet. At the same time, it receives the completion or alarm information of the control equipment and feeds it back to the logistics management system. All conveying equipment can be dispatched offline to complete the automatic material Transport, realize the smooth interaction and mutual coordination of enterprise work flow, logistics and information flow. The control system involves network technology, database technology, radio frequency technology, visual recognition technology, radio communication technology, infrared technology, laser positioning technology, industrial control unit technology, etc. The hardware adopts international advanced servo control system and address system for full closed-loop control and operation The precision is higher, and the control program adopts a reliable and stable modular design, which greatly improves the efficiency of the staff.
