Design And Research Of Electronic School Citation System Based On Internet Of Things Technology

At present,there are nearly 100 million students in China.The construction and safety management of the campus is one of the key points of government work.The school has made great progress in management informationization.However,the existing management systems generally lack the student positioning function.Although many primary and secondary schools have initially completed the construction of campus network infrastructure,the application of the network is still limited to the basic level of equipment interconnection and data intercommunication,and did not give full play to the advantages of network technology in campus security,personnel positioning,etc.,and the mastery of student location information is one of the urgent needs of the school.With the development of the Internet of Things technology,ZigBee technology has attracted more and more attention from researchers and technicians because of its self-organizing network,low power consumption,and stable and reliable information transmission.At present,ZigBee technology has been developed very mature in foreign countries.Although the development of ZigBee technology in China started relatively late,the development momentum has been widely used in the fields of smart home and building automation.This paper relies on the Jilin Province Science and Technology Development Plan project: based on the research of key technologies of safe campus construction based on multi-sensor big data fusion,using ZigBee wireless technology to design a set of electronic school badge system with positioning function to solve the problems related to student positioning.The hardware design of this system mainly includes: the design of CC2530 core chip,the design of electronic school badge power supply,and the selection of inertial chip.The software design mainly includes the software design of the electronic school badge,which is mainly the realization of the positioning algorithm and the server design.In terms of power supply,the electronic school badge is powered by solar energy and does not require repeated charging.In terms of positioning datatransmission,the electronic school badge first sends the student location information to the gateway through the ZigBee network,and then the gateway uses the TCP/IP protocol to send to the host computer through the Inernet.In terms of positioning algorithm,in order to improve the positioning accuracy,this paper uses the combination of inertial positioning and ZigBee positioning to realize the fusion of the two data through Kalman filtering algorithm.This paper finally completed the hardware design of the electronic school badge and the program design of the software part,and successfully realized the positioning function of the electronic school badge system.Through the actual test and test,the accurate positioning of the students is realized,and the error range is about 1.4 meters,which can meet the actual needs and prove that the technical scheme of this paper is feasible.At the same time,the system is low in cost and suitable for large-scale promotion,with great development potential and market prospects.
