Keywords: EMS energy management and control platform; Energy saving and consumption reduction 0 Introduction Acquaray EMS energy management and control platform adopts a new cutting-edge energy-saving technology means, which uses the Internet of Things, cloud computing, Internet, big data, artificial intelligence and other technical means to monitor the energy system operation of steel plants in all aspects, and provides data support for production organization, energy scheduling and other energy business management, and through systematic management, so that steel plants can achieve the purpose of
using energy and saving energy.

Numerous cases at home and abroad show that many industries have benefited
from the construction and application of energy management systems.

The steel metallurgical industry is not only a large energy user, but also a large production capacity, so the rational planning and utilization of energy is particularly important
.

The establishment of a long-term and reasonable energy management system can not only reasonably reduce the unreasonable phenomena in the production organization mode of steel plants, the use of process equipment construction and the status quo of management and scheduling, but also change the problems of
high energy consumption, unsatisfactory environmental quality and serious waste of energy management mode.

1 The technical route and significance of the construction of the Ankerui EMS energy management and control platform The Ankerui EMS energy management and control platform mainly uses various technical means to save energy and reduce consumption, optimize transmission and distribution, rational use, green and clean production as the goal, through technical means or collection and management equipment will be distributed in all corners of the steel plant automation control equipment, energy instruments, environmental sensors and other industrial units to integrate and connect, forming a data information network.
According to the business management needs of the steel plant to obtain data in real time, and on this basis according to different business needs to establish a variety of energy production control mathematical models and management models, and then with a variety of feature-rich software, systems as the carrier of data calculation, display, management, in different information forms for the steel plant enterprise at all levels of users, real-time, all-faceted, three-dimensional display of the workshop area, the plant area and even the entire steel plant area of the energy configuration and use of the status quo, process equipment operation status, logistics organization status, Status quo of environmental management, etc
.

It provides users with instant adjustments to the current production form, while providing a data analysis basis for the next stage of work organization direction decision-making
.

Through the implementation of energy concentration, flattening and fine control, the EMS energy control platform can reduce labor costs, improve the management efficiency of steel plant enterprises, reduce the transaction disposal links, and provide basic data for the refined management of steel plants, which plays an important role in optimizing the balance of energy production and consumption, reducing carbon emissions, improving environmental protection quality, and reducing the unit consumption of steel production, and it plays an important role in the formulation and implementation of accident plans, rapid analysis of accident causes and timely judgment and processing of accidents.
The reasonable adjustment and balance of energy supply and demand under normal and abnormal conditions is very reasonable

2 Architecture composition and software functions of Ankeri EMS energy management and control platform2.
1 Ankerex's EMS energy management platform network architecture Ankeri energy efficiency management scheme consists of
equipment layer, transmission layer, data layer and service layer.

The equipment layer (which steel mills need to install electricity, water, gas and other energy metering equipment) communicates via RS485 dedicated line or wireless
.

The transport layer (edge computing gateway) can collect terminal device data through RS485 dedicated line or wireless communication, and transmit data to the data layer
by Ethernet or 4G, NB, etc.

The data layer (generally deployed in the steel plant machine room server) processes the upload data of the transport layer and serves the service layer business, which can be connected
with the production system of the steel plant or other related systems.

The service layer (typically deployed in steel mill room servers) provides data analysis, energy management, energy consumption forecasting, event alarms and other functions
