The energy consumption online monitoring system consists of main parts such as the perception layer, transmission layer, platform layer, and display layer. The perception layer is composed of various front-end devices such as electricity meters, water meters, gas meters, and sensors installed on the production and living sites. 
The front-end devices collect energy consumption in real-time. The transmission layer is that after the data is collected, by using devices such as smart wireless gateways and wireless routers, the data is transmitted to the management platform through 3G/4G, Ethernet, etc. And the platform can also send control commands to the front-end equipment through the network. 
The platform layer is the "brain" of the system, The energy consumption data platform integrates the collected and transmitted energy consumption data to form a database, stores, analyzes, and processes the data, and issues relevant instructions according to the results. 
The display layer is the visualization of data through reports, graphics, etc. After processing, it will be displayed to enterprise personnel, and provincial and municipal managers on clients such as computers, mobile phones, and iPads.

In the energy consumption online monitoring system, Qiyang i.MX6UL embedded hardware is applied to intelligent wireless data acquisition gateway equipment with the advantages of low cost, high performance, and high reliability to realize access control, data collection, and reporting of front-end monitoring equipment. The main frequency of Qiyang intelligence i.MX6UL core board can reach 528MHz, 512MB RAM, 4GBeMMC Flash, large-capacity storage configuration, and support data local storage. The data transmission gateway device using the i.MX6UL processor can choose different configurations of memory to more flexibly support various needs of customers. And it can provide RS485/RS232, Ethernet, 4G, Wi-Fi, LoRa, and other network communication interfaces, support multiple network protocols, automatic switching of network failures, and ensure data transmission security. It supports Linux operating system, and provides source code and technical support, which is convenient for the secondary development of users. Selected High-quality industrial-grade devices are suitable for various complex industrial environments and realize efficient and reliable data transmission.
Qiyang intelligence series intelligent gateways use high-performance industrial processors to provide powerful edge computing performance. The full industrial-grade design can quickly realize network transmission management, data collection, storage, routing, forwarding, equipment linkage control, and system remote maintenance of various equipment on the industrial site.
With the rapid advancement of the "dual carbon" policy, online energy consumption monitoring systems are not only used in the industrial field, but also in smart cities, smart parks, and smart buildings scenes.
