The equipment on the logistics transportation line is divided into core equipment and common equipment.Each transportation link is composed of a piece of core equipment and a lot of general equip-ment.At present,industrial production is diversified,because of the change of customers and product,the logistics transmission line needs to be changed frequently.The core equipment is responsible for de-centralization of the logistics transmission line,so that the production line can be rebuilt more flexibly.For this reason,we designed the core equipment with STM32F407VET6 as the controller.The actual use of the product has proved that it has achieved the predetermined goals and realized the requirement of flexibilization of the production line.
