Design And Realization Of Wireless Lock System Based On ZigBee

There are many problems in the management of public rental housing,such as the difficulty of management of rent collection and tenant access control.How to realize the intelligent management of public rental housing has becoming a research highlight.In view of the problems in the management of public rental housing,this paper puts forward a solution of wireless door lock system based on ZigBee technology.This solution combines RFID technology and high concurrency of Node.js.After extensive study of ZigBee and RFID technology,this paper designs an overall framework of system according to the system demand analysis and gives a concrete realization scheme.The main work and achievements are as follows:1.The theory and implement of ZigBee technology are studied.The hardware is designed based on the theory of ZigBee.The CC2530 microcontroller and the Z-Stack protocol are used to design the door lock controller and the base station controller.The design of network structure is based on star topology.At the same time,the low power consumption of the door lock controller is designed.The door lock is powered by four AA batteries,which can work for one year or more.2.The realization of RFID technology is studied.Focus on the design principle and requirements of the RFID circuit,this paper designs driver circuit of a 13.56 MHz RFID card reader.The card reader can not only read and write Mifare One cards,but can also read the UID of China second-generation identity card.3.The software design of host computer is composed of management and communication software.The management software of the wireless door lock system is designed as B/S architecture.The Web server and responsive web pages are designed and the HTTP protocol is used for communication between the server and client.Host computer and the base station controller are designed for Ethernet communication.Communication software is designed as TCP server based on high concurrency of Node.js.Finally,the system is tested and the test results are recorded.The test results show that the system can meet the needs and realize the intelligent and mobile management of public rental housing.
