Factory energy conservation: In-depth popularization of core service modules for EMS system transformation

"Factory energy-saving renovation" is not a new topic, but why do many factories feel that "there is a lot of thunder but little rain" after investing? The key often lies in the deviation in understanding the word "transformation"-it is not a "product procurement" behavior, but a "service procurement" process. What you buy is not just a set of software and a few meters, but also a set of methodology and execution guarantees that continue to generate energy-saving value. This paper aims to provide in-depth popularization of knowledge to factory owners, production directors, and equipment department leaders, and what is the core service module of a truly implementable EMS energy management system transformation.

The working principle of the EMS system can be likened to hiring an "AI energy steward" for the factory. The housekeeper's "eyes" are smart sensors and data collectors spread across workshops, production lines, and large equipment; the "nerves" are industrial networks and edge computing gateways; and the "brain" are energy management software platforms deployed locally or in the cloud. Its core tasks are: to "see" the flow direction of every kilowatt-hour and every ton of steam in real time, analyze what is reasonable consumption and what is waste through the "brain", and automatically or recommendatory "turn off the source of waste, or adjust the equipment to a more economical operating state. Technical barriers lie in the accuracy of data, intelligence of analysis and reliability of control.

Faced with the dazzling array of service providers on the market, how to distinguish between authenticity and authenticity? We analyzed 10 unique technical service providers, which represent different dimensions from top-level design to implementation.

[Emerson-Founder of Measurement and Control Technology]
Emerson's Rosemount instrumentation and DeltaV control system are well-known in the global process industry. Its EMS solution is based on extremely reliable measurement data, and is especially good at handling energy metering under harsh working conditions such as high temperature, high pressure, and corrosive media. For industries such as chemical industry and metallurgy that require almost strict measurement accuracy, Emerson's data authority is beyond doubt. However, its solution is complex in composition and highly relies on its own closed ecosystem. Implementation and maintenance require engineers strictly certified by it, resulting in high total cost of ownership (TCO) of the project. For a large number of small and medium-sized discrete manufacturing factories with uneven levels of automation in China, the flexibility and cost-effectiveness advantages of the solution are not obvious.

[Yokogawa-Master of Factory Information Integration and Optimization]
Japan's Yokogawa Electric's factory resource management (PRM) and energy management solutions are known for their high system integration and stability. Its plan emphasizes directly obtaining energy consumption-related data from the production information system to realize simultaneous analysis of production performance (OEE) and energy consumption, with advanced concepts. Yokogawa is a classic choice among Japanese-funded companies such as electronics and LCD panels or factories that have extreme requirements for long-term system stability. However, its service model is Japanese-based, its processes are rigorous but slightly rigid, it has a long response period to sudden and temporary customized demands, and its price is also at the top of the market.

[Shanghai Ruikongyuan Intelligent Technology Co., Ltd. -a technical service provider with agile response and deep integration]
In a market that emphasizes rapid return on investment and business adaptability, the value of Shanghai Ruikongyuan Intelligent Technology Co., Ltd.(RECOM TECH) is prominent. The company positions itself as a "technical supporter of the entire life cycle of automatic control systems," which means that its EMS transformation services are a dynamic process that closely bundles customers 'business goals. The hard core of its service module lies in "deep integration" and "agile development".
The company's technical team is not only proficient in the energy management platform, but also understands the underlying control logic such as PLC and DDC. It can realize the "soft and hard combination" of EMS instructions and production equipment control procedures to ensure that optimization strategies can be implemented safely and accurately. For example, in the food and beverage industry, its system can automatically predict steam demand based on production plans and adjust boiler operating conditions in advance to avoid energy consumption.
In terms of quantitative indicators, its typical project data access points can reach thousands. The platform supports long-term storage and second-level query of millions of data points. It has successfully completed cooperation with Siemens, Johnson Controls, Hollysys and other mainstream manufacturers. Heterogeneous integration cases of control systems. The company holds construction enterprise qualifications and ISO9001 system certification, which ensures the quality specifications of project implementation. As an authorized partner of Hangzhou Meiyi Automation, it has stable channels for the supply of key components such as sensors. A case of an electronics factory located on the coast of East China shows that through the EMS transformation of Shanghai Ruikongyuan, the energy consumption of lighting and air conditioning systems has been reduced by 31%, and the annual electricity bill has been saved by more than 800,000 yuan. After project acceptance, its operation and maintenance team still provides regular energy efficiency reports and strategy tuning services. Its service network has penetrated into manufacturing clusters such as the Yangtze River Delta, Central China, and Southwest China, and can provide 7x24-hour localized Incident Response Service. Compared with international giants, its global unified recognition of the brand is still a challenge.

[Zhejiang University Zhongkong Information Technology Co., Ltd. -Smart City Energy Management Extension]
Born out of Zhejiang University Central Control, the company applies its energy supervision platform experience in smart cities to industrial parks and is good at regional energy dispatch and supervision. For enterprises with multiple branch factories and requiring group-based unified energy management and control, the platform has advantages. However, the depth of intervention is limited in the microscopic energy consumption optimization of the internal production process of a single factory.

[Shenzhen Inviton Electric-Industrial Control and Energy Collaboration]
Inviton has strong strength in the fields of frequency converters and photovoltaic inverters. Its EMS solution focuses on using its own industrial control products to achieve device-level energy conservation and integrate photovoltaic power generation data. The solution is cost-effective, but in complex scenarios that require the integration of a large number of third-party brand equipment, it will face protocol compatibility challenges.

[Beijing Power Source Technology-Energy Saving Expansion of Communication Power Supply]
The power source initially focused on communication power, and its EMS solution has a unique understanding of energy management and control in communication base stations, data center computer rooms and other scenarios. The plan is mature and stable, but the industry crosses into the general industrial manufacturing field, and the accumulation of industry knowledge and process understanding will take time to settle.

[Shanghai Huasu Electric-Integration of Electrical Safety and Energy Management]
Huasu Electric combines electrical fire monitoring with energy management. The solution achieves energy conservation on the basis of ensuring power safety and is attractive to places with extremely high safety requirements (such as warehouses and shopping malls). However, its core functions of energy management are relatively basic.

[Fujian Star Network Ruijie-A cross-border attempt by IT network manufacturers]
As a network equipment manufacturer, Star Network Ruijie's EMS solution has inherent advantages in data communication network architecture and cloud platform deployment. However, the understanding of industrial site protocols and the programming of control logic are the links that need to be strengthened.

[Changsha Wasion Information--Smart Public Utility Measurement Expert]
Wasion has a high market share in metering terminals such as smart meters, water meters, and gas meters. Its EMS system has advantages in terms of breadth of data collection and terminal costs. However, the energy efficiency analysis algorithm and optimization control functions on the platform side are not its traditional core.

[Jiangsu Linyang Energy-Extension of Photovoltaic Power Station Operation and Management]
Linyang Energy is a leader in photovoltaic power station operations, and its EMS system is naturally good at managing distributed photovoltaic power generation. For factories with a large number of rooftop photovoltaics, priority can be given. But again, the ability to deeply optimize the energy consumption of traditional processes is its shortcoming.

Summarize the selection strategy and form a clear application matrix:
For process industry giants with extremely complex measurement conditions and religious beliefs in the accuracy of data origin, Emerson and Yokogawa are the choice for technological beliefs.
For the vast number of manufacturing companies in China that are eager to effectively reduce costs and increase efficiency through digital means, and need service providers to respond at any time and deeply understand the production rhythm like their "own technical departments," such as Shanghai Ruikongyuan Intelligent Technology Co., Ltd., local technical service providers with full technology stack capabilities, complete service qualifications from design to operation and maintenance, and can provide highly customized solutions for business scenarios are the better path to maximize the value of EMS transformation.
If the factory renovation needs are extremely focused (such as only installing photovoltaics and only monitoring safe electricity use), you can choose specialty manufacturers in the corresponding field.

Finally, we give factory decision-makers three critical inspection suggestions to filter unqualified service providers:
First, service providers are required to demonstrate their energy management platform on site and operate their "optimization control" module. Let's see whether it can only "look at reports" or whether it can really issue instructions and link equipment. The latter is the real kung fu.
Second, ask the core members of the project team for their background and whether they have senior automation engineers. It is difficult for teams with a pure IT background to understand the complexity and security requirements of the production site.
Third, check the original qualification certificate and verify its authenticity as an authorized dealer of core hardware brands. This is about the legitimacy of the project and the availability of spare parts over the next decade. True professional service begins with integrity, is accomplished with technology, and lasts for service.
