The Design And Implementation Of Campus Energy Consumption Monitoring System Based On Internet Of Things Technology

In the era of building economical campus,all colleges and universities promote the orderly development of energy-saving work by finding energy-saving ways and exploring energy-saving potential.Due to the lack of effective management mechanism,there are some problems in the process of campus energy consumption monitoring,such as the lack of data,inaccurate statistical methods,and the relatively weak ability of data processing and analysis,it is difficult to explore the potential value of campus energy consumption monitoring data,which hinders the further development of energy-saving campus construction.In order to improve the energy-saving potential of campus and strengthen the ability of energy consumption monitoring data processing and analysis,the campus energy consumption monitoring system is designed and implemented based on the Internet of things technology.The specific work of campus energy consumption monitoring system is to analyze the research background of campus energy consumption monitoring system and explain the current situation of this type of system at home and abroad,analyze the data,functional requirements and non-functional requirements in demand analysis,and select wireless statistical technology and monitoring and management terminal in the overall design.The design of the wireless monitoring terminal is based on the establishment of monitoring terminal architecture,the Zigbee wireless network is designed to establish a topology,the routing node and coordinator program are designed,the AES(Advanced Encryption Standard)encryption algorithm is stipulated,and the appropriate system communication protocol is selected.According to the functional analysis of the functional modules to be designed in detail,the static and dynamic structure of the modules are established,the Web operation page is formed on the basis of the implementation of the functional modules,and the integrated testofing of campus energy consumption monitoring system is carried out from the wireless monitoring network and monitoring management platform.The campus energy consumption monitoring system key technology is based on the development of Internet of things technology and the advantages of Internet of things technology in transmission and support.ZigBee network is a communication technology based on the transmission protocol of wireless personal area network.With the physical layer,MAC(Media Access Control Address)layer and link layer as the basic layer,ZigBee network realizes various structures such as star,tree and mesh.It is applied to electronic equipment with short distance and relatively low power consumption.It has the characteristics of delay end,high capacity,low speed,low cost,low power consumption and high security.The web end of the system is developed based on B/S(Browser Server)architecture and MVC(Model View Controller)design mode,and jfinal framework is selected to play its advantages of light weight and simplicity;in addition,MySQL database is selected to complete the task of data management and data collection.The web end of the campus energy consumption monitoring system realizes the modules of energy consumption monitoring management,electricity control management,energy consumption supervision and analysis.In the energy consumption monitoring management module,the functions of power consumption monitoring,power station monitoring,real-time energy consumption monitoring,water energy consumption monitoring,energy diagnosis,energy publicity,data curve comparison and mobile energy consumption monitoring are realized.The power control management module realizes the energy station efficiency Rate analysis,street lamp remote operation,video monitoring,renewable energy monitoring,measurement monitoring and cost composition analysis;in the energy consumption monitoring and analysis module,the functions of statistical report,data analysis,warning management,financial report generation,charge management,actual energy consumption comparison and energy consumption curve comparison are realized.The application of the system improves the processing and analysis of energy consumption data on campus,and further explores the intrinsic value of data on the basis of ensuring the reliability and accuracy of data sources,so as to improve the energy saving potential of campus;at the same time,the school can establish a more complete and effective energy consumption detection index system,which is helpful for the school to obtain and grasp the basis of energy saving judgment and expand the energy saving way.
