1  The system realizes the function

• Multi warehouse deployment ： The deployment mode adopts high frequency RFID The brancher is placed in the center of the storage position , high frequency RFID The way the antenna extends outward , It can monitor multiple storage locations at the same time .
• Storage function ： The goods in each storage location can be warehoused at any time , By mobile phone APP Enter the name of the goods 、 Place of Origin 、 Date of manufacture 、 Shelf life and other information , When leaving the warehouse , The user is in APP Just clear the information on , After clearing, the storage bit is idle .
• Inventory counting function ： The client can view the idle status and location of the storage space in real time .
• One key warehousing function ： The interactive interface of the system adopts a unified and concise layout style , Quickly carry out relevant business operations , The warehouse information entered by the operator for a long time shall be filled in with one key , Improve work efficiency .
• APP Query function ： Users through the mobile terminal APP Name of goods in all storage locations 、 Date of manufacture 、 Origin 、 Write the shelf life , The mobile terminal can check the shelf life of all stored agricultural products in real time , It is convenient to take measures to reduce losses .

2  Overall design of the system

2.1 Device awareness layer

        high frequency RFID Branching device and high frequency RFID Design of antenna nodes ： Through various high frequencies RFID The antenna node simulates the storage location of goods , And through high frequency RFID Read / write module acquisition Mifare S50 Cargo information in the card , The cargo information obtained by each node is sent to the high frequency through the RF antenna RFID Branching device , In order to achieve the above functions , use Keil µVision4 Embedded development environment , use STC12C5A60S2 Single chip as the main control chip , Write RF time-sharing reading and writing program to realize the high frequency RFID Read and write cargo information on antenna nodes .

2.2  Network transport layer

        WiFi Design of wireless communication module ： adopt WiFi Wireless networks will be high frequency RFID The cargo information obtained by the branch is uploaded to the mobile terminal , Realize the remote interaction of data .

2.3 Application Management

        Android Client design ：Android The client is the display end and the interaction end , Design goods management interface and shelf management page to manage goods and storage spaces respectively , use Android Studio Android development environment for goods warehousing 、 Inventory 、 Development of query and other functions .
