Design And Implementation Of The Supervision System Of Liquor Cellar Based On RFID

The so-called Liquor Liquor Bank is to provide wine drinkers with professional business services for the storage of wine in cellars.However,the security issue of Fengtan Liquor has been plaguing customers and service providers.In order to solve this problem,this paper applies RFID(Radio Frequency Identification Technology)to the supervision system of white wine cellars,and designs and improves related algorithms,thus realizing a monitoring system for white wine cellars based on RFID.This article first designed the active RFID.In the hardware design of active electronic tags,vibration sensors and loop detection are added.At the same time,the battery voltage status of active electronic tags is monitored through program design to achieve the purpose of timely replacement of batteries with undervoltage active tags.Secondly,in the reader's hardware design,the temperature and humidity sensor and the main control chip STM32C8T6 and the serial port to WIFI module were added.At the same time,the low power consumption problem of the tag,the collision between the tag and the reader,and the tag and the reader were added.Between the authentication problems,the anti-collision algorithm,low-power algorithm and authentication mechanism were designed;finally,the background monitoring system was designed.In order to achieve regulation of liquor,the system is divided into active RFID data collection end and back office supervision system.The reader interacts with the information received from the tag through the wireless WIFI and the background monitoring system,uploads it to the background using the TCP/IP protocol.The background monitoring system will receive the data sent by the reader and store it in the My SQL database to realize the functions of displaying the supervision data,alarming and pushing the alarm message to the customer.Finally,through tests and experiments,it is proved that the system can realize real-time intelligent supervision of wine cellar liquor,and it has good real-time performance and stability.
