2.4GHz active RFID positioning system
VANCH Active RFID warehousing management system is the integration of 2.4G active RFID technology, network communication technology and computer software technology by VANCH INTELLIGENT, to solve the problem of enterprises’ difficult warehousing and others, and to finish real-time accurate location on GOODS.
Main functions of VANCH active RFID warehousing management system：Ø Automatic record on output and input of warehouse；Ø Fast search location of goods；Ø Goods navigation system；Ø Quick inventory；Ø Stock alert；Ø Materials shortage alert；Ø Accurate location system；Ø Video linkage display function；2 INTEGRATED SYSTEM DESIGN FRAMEWORK
The system includes 3 parts：
1．Real time accurate location system；
2．Goods output and input of warehouse automatic management system；
3．System management platform.
2.1 REALTIME ACCURATE LOCATION SYSTEM
Principle of warehouse real time accurate location system：
1．Install one VT-3001 2.4G active RFID tag on each item.
Features of the tag: once tag is attached to the item, it will start to work；with motion detection function, when item moves on, it will transmit data once at 1 second interval, when item no moving, it will transmit data once at 15 minutes interval；can be controlled by locator（sending frequency, power and etc.）.
2．Install VP-510 locator on goods shelf. The function of the locator is to receive tag information, control tag’s transmitting power, control address information transmitted by tag and etc.
Process：
To location accurately, tag transmits signal to locator; locator controls the power and speed of tag transmitting signal to confirm tag’s accurate position; after locator finish the accurate location, it will send information to reader; reader will finally confirm the specific goods shelf of tag by probability distribution statistics and save in the system.
When user want to check the item’s position, it will be displayed soon. And reader will send the command of indicator light ON to locator. When open linkage monitor, user can see the item’s specific location through video.
2.2 GOODS OUTPUT AND INPUT OF WAREHOUSE AUTOMATIC MANAGEMENT SYSTEMIt’s to automatically record the information of the goods output and input of warehouse. Install 2 sets of readers VI-710/W in the warehouse entrance and exit, one facing outside, another facing inside.
2.3 SYTEM MANAGEMENT PLATFORM
The whole system platform as follows：
1．The platform of Internet of Things is for data acquisition, analysis, processing and etc.；
2．Database is the collection point of all data；
3．Webmaster is for network management；
4．BS server is to build web server for user.
