3 The overall system architecture design

3.1 Hardware support

In the warehouse area, the enterprise LAN is used, equipped with a certain number of computers and servers. In order to facilitate the operation of handheld RF, the automatic identification of vehicle terminals, and RFID access doors, wireless APs need to be used in the warehouse to meet the needs of data transmission and users. In addition, corresponding auxiliary equipment such as printers needs to be added to realize functions such as printing of reports, bar codes, and storage positions.

3.2 Software support

Adopt B/S structure and component development technology based on J2EE or .NET multi-layer architecture to design and develop the system architecture, and install the WEB browser to access the TCP/IPTV end of the Internet in the enterprise. Users only need to use a Web browser to process the operations of various functional modules in the system. The advantage of the B/S model is that it can reduce the workload and cost of system maintenance and upgrades, and it also simplifies the client and facilitates operation.

Develop in accordance with unified data standards, including metadata standards, master data standards, information classification, and coding standards, etc., to ensure the standardization and consistency of information system data, and to meet the requirements for full data sharing and application. The intelligent warehousing system uses the Oracle 12C database as the data layer of the system. Oracle 12C database can improve the access efficiency of data files and help different types of data queries. It can effectively solve the detection of system database quality inspection and resolve conflicts. In the development and design of the system, the database is connected through RedHat Linux 7.5, and SQL statements are executed to complete data checking, adding, deleting, and modifying.

4.3 Quality Inspection Management

Quality inspection management means that operators complete quality inspection actions on corresponding areas through mobile terminals. The user can perform quality inspection operations on the materials stored in the library. The system defaults to listing the locations with the material status as “Pending Inspection” for users to choose (the user can specify all locations in a certain area, a certain location, or a certain category). Materials undergo quality inspection). After the user inspects the materials, the current quality inspected materials can be processed in the status of “Quality Inspection Passed”, “Quality Inspection Unqualified” or “Pending Inspection”.

4.4 Maintenance management

Maintenance management is the regular maintenance and maintenance work performed by warehouse managers on stored commodities. Based on the use of wireless sensor equipment, temperature and humidity detectors, and other technologies to detect the storage environment in real-time, from maintenance method collection, maintenance strategy management, maintenance strategy preparation, maintenance plan adjustment, historical maintenance tasks, maintenance task allocation, historical task management, and maintenance tasks Early warning, maintenance operation tracking, and maintenance operation adjustment dimensions, establish material maintenance goals, data collection, task allocation & early warning, historical data query, maintenance adjustment closed-loop control, through the above management measures to achieve the full life cycle of tobacco in the warehouse Management, it is convenient for us to view historical data and do subsequent storage and maintenance operations.
