Control Item Identification System Based On Electronic Label

In recent years,the construction of information technology and social information in our country has entered a stage of rapid development,and people's life has also changed dramatically,and the management of management and control of the current society is becoming more and more automated and intelligent.At present,most management ways of control items are recorded in paper bar code,which are the types,models and date of production of the controlled articles.Then the paper bar code labels are attached to the articles.The bar code reading equipment reads the information of the bar code storage through the bar code reading equipment to realize the management of the controlled articles.This management item management scheme,once the management and control of the use of units,users,responsible people change,paper bar code storage information is difficult to update in time,to bring great inconvenience to management.Traditional management methods are inefficient,secure,unable to guarantee,process cumbersome,and limited storage information,which can no longer meet people's growing demand for management.Not only that,but because of the particularity of the control items,once managers fail in the management process,they will cause serious consequences.At present,various industries have increased investment in management and control of goods,and put forward their own internal standard management methods.In view of the above situation,combined with the current technology of Internet of things,this paper puts forward the application of RFID technology to the unified management of controlled goods.RFID is one of the representative technologies in the Internet of things.It is an important means to realize intelligent management.Its non-contact communication,long distance recognition ability and high security have provided a good solution for management and control of articles.In this paper,the STM32F103VET6 processor based on ARM Cortex-M3 is used as the core circuit of the embedded control design.The AS3992 read and write device chip is used to read and write the electronic label,and the GPRS module and the WIFI module are used to design the peripheral circuit of the wireless transmission module and the remote host for data transmission.In the electronic label,the related information of the control items is stored and bound with the control items.The hardware circuit is built and the related software control program is written to realize the identification of the control items.The STM32 control module is the core part of the whole system.It mainly controls and coordinates various functional modules,including controlling the reading and writing modules of the RFID reading and writing modules,and controlling the functions of the wireless transmission module to complete the data upload and so on.Through the independent selection of WIFI mode or GPRS mode,the wireless communication connection and data transmission are established with the host.The data is identified and processed at the host side,and the research goal of the paper is completed preliminarily.
