Design Of RFID Public Restaurant Dining System

Under the influence of the epidemic,the number of people dining in public restaurants in schools and enterprises has soared.Along with this circumstance,core issues such as low dining efficiency of public restaurant dining staff,a lengthy dining settlement procedure,and too close interaction between dining staff and their contact with staff are becoming more prevalent.To solve these problems,this thesis designs a dining system for public restaurants with RFID as the main technical means.The dining system is mainly divided into two parts: the lower computer system,which is responsible for data collection and transmission;the other is the upper computer system,which is responsible for data processing,storage,and display.Firstly,we designed the lower computer system consisting of tableware and an RFID system integrated with the dinner plate.To meet the requirements of the application scenario,the RFID reader is selected from the austriamicrosystems AS3992 reader module;the reader antenna is a UHF near-field antenna;the passive UHF tag corresponding to the reader and antenna frequency is selected for the tag,and the nonopen FKFCJ-96 coding scheme is designed according to the EPC coding specification,and the GPRS module to transmit data.After the completion of the design of the lower computer system to read and write performance of the RFID system and GPRS module data transmission reliability testing,the test results show that the lower computer system can complete the data acquisition and transmission functions.The PC management system is developed with three-layer B/S architecture,applying HTML interface to interact with users,Java language to realize business logic,and My SQL database to realize the data storage,whose functions include Its functions mainly include user management,role management,authority management,chef management,diner management,dining information,plate management,and system database;middleware receives data from the lower computer and processes it through socket communication and multi-thread technology,and sends the processed data to the upper computer;mobile APP bill inquiry and payment system are developed with C/S architecture,and the main functions include login module and The main functions include login module and dining information module.Finally,the dining system of the public restaurant is connected with hardware and software and tested.During the test,the system runs as follows: simulating the actual working environment of the system,the reader in the plate reads the tableware tag located directly above the antenna,the reading command is sent by the middleware via TCP/IP protocol in wireless transmission,the reader receives the command,reads the tag and returns the tag data,the middleware receives the returned information for analysis and processing,and stores the tag data belonging to the system in the database.The upper computer management system refreshes and displays the corresponding tableware information and consumption information,and the diner can view the corresponding information and pay through the cell phone APP.From the test results,it can be seen that the system has accomplished the design goal and can improve the dining efficiency and safety of the dining staff in public restaurants to a certain extent and reduce the workload of the staff.
