The Design Of Energy Consumption Monitoring System For Office Building Based On Bus And Ethernet

Energy is the driving force of social and economic development, and it is the material basis for the survival and development of human society. With the rapid development of China’s economy, urbanization, industrialization accelerated, the demand of domestic energy is increasing. However, the energy consumption in our country is still dominated by coal, and the pollution caused by dust, SO2 and so on, which seriously affected the ecological environment and people’s life. Therefore, the energy saving measures for us is very urgent.According to statistics, the global building energy consumption accounts for about 41% of the total energy consumption, which has more than the energy consumption of industrial and transportation and become the first energy consumer. Among them, the energy consumption of the large public buildings and state organs office buildings is the most prominent. Therefore, the research and establishment of public building energy consumption monitoring system for reducing building energy consumption, improve energy saving management level has important significance.In order to achieve energy saving and consumption reduction, this paper designs a energy consumption monitoring system based on RS485 bus and Ethernet. Through the RS485 bus, the data of each classification item is collected. And the energy consumption data is uploaded to the database. The data from the database was read and display, analysis through the system monitoring platform so as to achieve real-time monitoring of office buildings energy consumption.The research results of this paper are:the distributed acquisition of energy consumption is realized by establishing the data acquisition and transmission network based on RS485 bus and Ethernet., the energy consumption of the office building is put forward combined with the energy consumption of office buildings, and the software and hardware design of the monitoring system is completed. Thus the basis was provided for the office building energy efficiency assessment and transformation.
