Abstract:The rapid development of computer technology, internet technology and IOT technology contributed to the continuously deepening reform and development of the logistics industry in China。 By analyzing the development of warehouse management system and the traditional warehouse management system at home and abroad, this paper designed the IOT-based intelligent warehouse management system by utilizing the technologies of IOT, sensor, wireless communication, and modern logistics management。 As the center of control, data processing and networking of the intelligent IOT warehouse, the warehouse data processing system acts as the core component of warehouse management, and is also the most challenging part in designing the system。 With that in mind, this paper transplanted the embedded Linux system on the FS4412 development platform of Cortex-A9; and by analyzing the functional requirements of warehouse management, the inter-process communication and multi-threading technologies of Linux were utilized to design the overall software structure of data processing system。 Specifically speaking, this paper elaborated the design and implementation of functional modules regarding warehouse data receiving, processing, storage and device control, accompanied by the test on system stability and data transmission accuracy。
