Abstract
This paper designs and implements an energy management system based on the Spring Boot framework. The system mainly includes three layers, which are the data collection layer, the business logic layer, and the display interface layer from bottom to top. The data collection layer is based on the RS-485 electrical standard and the MODBUS communication protocol. The two protocols connect all energy consumption monitoring points into a mixed topology communication network in the enterprise. The programs in the data collection layer poll each energy consumption monitoring point in the network to collect the data and transmit to the business logic layer. The business logic layer is developed on the basis of the Spring Boot framework and mainly includes two parts: the MySQL database and Tomcat server. In the MySQL database, the stored data are horizontally split according to the time column and stored in different data tables. The split of data reduces the load of a single data table and improves the query performance of the database. The Tomcat server is built into the Spring Boot framework to provide a basic environment for system operation. The Spring Boot framework is the core component of the system. It is responsible for collecting, storing, and analyzing data from energy consumption monitoring points, receiving and processing data requests from the display interface layer. It also provides standard data interfaces to the external programs. The display interface layer is developed on the basis of the Vue framework and integrated into the Spring Boot framework. The display layer combines an open-source visualization chart library called ECharts to provide users with a fully functional and friendly human–computer interaction interface. Through the calculation of hardware and software costs, considering the personnel cost in different regions, the total cost of the energy management system can be estimated. The cost of construction was approximately 210,000 USD in this paper. Since the system was actually deployed in a manufacturing company in December 2019, it has been operating stably for more than 600 days.
Highlights
Energy is the lifeblood of the national economy and the foundation of industrial development
It is of great significance to establish an energy management system and fully control the total energy consumption of the enterprise to improve the energy utilization rate [2]
Focusing on the above problems, this paper designs and implements an energy management system based on the Spring Boot framework
Summary
Energy is the lifeblood of the national economy and the foundation of industrial development. Especially the manufacturing industry, consume huge amounts of energy such as water and electricity in the process of production These high-energy-consuming enterprises have to pay high energy costs each year, but the energy utilization rate cannot be effectively improved. The early energy management system was relatively small and simple in function It was mainly used for the collection and monitoring of energy consumption data and the control of equipment. China National Heavy-Duty Truck, Shanghai Automotive, and other manufacturing companies are actively building energy management systems, collecting, processing, and analyzing the energy consumption data of the enterprises. These companies gradually constructed energy management centers and carried out energy consumption optimization work. The functions realize the management and control of the energy consumption in the enterprise, so as to accurately manage and analyze the energy consumption of each region and each production process, as well as provide a reliable and scientific basis for the enterprise managers to formulate energy-saving plans
