Abstract:Traditional warehousing systems have many problems, such as low automation, inconvenient control, remote data storage and query nodes. Aiming at this kind of situation, a distributed storage system based on CAN bus is designed. The system takes portable computer as control station, and builds distributed network with controlled node based on CAN bus. The controlled node mainly consists of control circuit with MCU as its core and storage cabinet with controllable electromagnetic lock as its basic hardware. The control station sends control instructions to the controlled nodes through CAN bus to control the electromagnetic lock action of the storage cabinet and realize the remote control of the opening and closing of the cabinet door. Through the experimental verification, it is found that the distributed control network based on CAN bus has the characteristics of high reliability and fast data transmission. The warehouse system based on this network achieves the goal of centralized management and decentralized control. At the same time, it also verifies the feasibility of the application of CAN bus in the design of automatic control of warehouse system.
