Campus Energy Monitoring Data Acquisition System's Research And Application Based On LabVIEW

With the development of social economy and science and technology,the problem of energy shortage has become a hot issue in today's society.Our country has set the basic national policy of saving resources and protecting the environment,and the Third Plenary Session of the eighteen Central Committee also pointed out that we should strive to build a resource-saving society,and ultimately achieve the goal of sustainable development of human and natural.With the development of education in China,the energy consumption of campus building is an epitome of social energy consumption.The energy consumption is increasing.In order to actively respond to the eighteen major calls,control energy consumption and contribute to social construction,the building and building of campus energy consumption system is very important.Building energy consumption is an important part of the whole social energy consumption,especially the large public buildings in China.For society as a whole,building energy efficiency is an effective way to increase energy efficiency.In order to locate and control the energy consumption of large public buildings such as supermarket,government office buildings,hospitals and campus buildings,this paper designs a data acquisition system based on LabVIEW.In this thesis,the basic situation of campus energy consumption on campus was designed based on LabVIEW monitoring data acquisition system,the system uses the host computer and the next crew to work together,through the sensor and the next crew can determine interconnected indoor temperature and humidity,light intensity and Does anyone through,and use STM32 development board to achieve the drive and configuration of the sensor,enabling the electricity consumption data acquisition and control of energy consumption,the PC with LabVIEW graphical programming language such as a platform,real-time acquisition and analyze energy consumption data processing and display.At the same time,the design of the terminal based on the Internet,so that more people,in a wider range of sensors to share the energy consumption data and the status of the campus,so that the entire campus energy consumption monitoring system is more powerful and perfect.With load current waveform acquisition expansion board,real time monitoring and identification of a variety of types,power,electrical equipment running status and early warning;Can detect electrical aging and campus in violation of the use of electrical appliances;And loop can be determined using energy efficient appliances,itmake an accurate assessment for electrical load state.The building energy consumption monitoring system is made up of energy metering device,data acquisition and network communication equipment.The system has the function of data acquisition,data storage,data processing and analysis,system management,system running state monitoring and fault diagnosis function,and can transmit all kinds of data and information to the upper level.This system has been debugged and run in the laboratory,and the speed of collection,accuracy and speed of the system are basically in line with the requirements of the system,which lays a foundation for further building the standard platform of the campus energy consumption data acquisition system.
