Once the "14th Five-Year" industrial green development plan was released this year, carbon peaking and carbon neutrality quickly became central topics in the field of energy management and control. The plan clearly points out that it is necessary to adhere to the principle of giving priority to efficiency, put the improvement of energy and resource utilization efficiency in the first place, promote the scientific allocation and efficient utilization of energy resources, optimize production processes and processes, improve the output efficiency of unit energy resources, promote energy conservation and consumption reduction, and improve energy conservation. Quality enhancement.
This points out two energy-saving ways for enterprises to reduce carbon and carbon emissions: one is to optimize the industrial layout and process structure, and eliminate outdated processes and production capacity; the other is to rationally utilize new energy in accordance with the principles of open source, consumption reduction, energy conservation and efficiency enhancement And innovative technology, through the intelligent and efficient energy management and control platform system, improve energy efficiency, reduce unnecessary waste, and achieve energy conservation and emission reduction. Among them, the use of smart and efficient energy management and control systems to achieve emission reduction is undoubtedly the simplest, convenient and fast method.

1. Energy saving
Load identification and early warning limit the use of high-power electrical appliances
Through the identification of malignant loads and high power, it is linked to various early warning modes to limit the use of high-power electrical appliances, thereby reducing the energy consumption of the dormitory.
Transparency of electricity use information prompts students to save electricity independently
Using the Internet of Things and big data technology, students can check the electricity consumption and balance of the dormitory in real time through the mobile APP (currently, the country distributes 6 kWh of electricity to each student for free each month), so as to realize the students' independent power saving.
Remotely turn off the power supply in the dormitory at any time to prevent waste of electricity
Through the network connection, you can use the mobile phone APP anytime and anywhere to turn off the lighting equipment that is not in use in the dormitory, so as to avoid the waste of electricity caused by forgetting to turn off the power. After the project is implemented, the electricity saving rate is as high as 30%. In terms of infrastructure construction, due to the reduction in the laying of various cables, compared with the original budget of Heping Campus, 3.5 million yuan was saved.
2. Efficient management
Real-time checking of electricity consumption data to eliminate unsafe loads
Through the use of smart meter boxes, the application of the Internet of Things and big data technology, the real-time inspection of electricity consumption data is realized, and there is no need for logistics and building management to manually check the meters.
Real-time alarm for abnormal electricity consumption, quickly locate the illegal dormitory
Real-time alarm of abnormality is realized through the load identification function. Support a variety of power consumption alarm methods, including SMS alarm, voice alarm, mobile phone app display alarm, etc. Logistics management personnel can quickly locate the abnormal dormitory and view the information of dormitory members through the operation log of the mobile APP.
WeChat electricity bill payment, saving labor management costs
Students can check the remaining power in real time through the mobile APP, and purchase power in real time through WeChat payment on the mobile terminal, which saves the labor cost of the school logistics management department for power purchase.
Extend equipment life and significantly reduce O&M costs
The safety of the system is significantly improved. Since there is no large current impact event, the life of the equipment is guaranteed, and the later operation and maintenance costs are significantly reduced. There is no need to visit the door to check the malignant conformity to promote the development of a harmonious campus. The research report on the smart power project of Sanchuan Zhikong Gansu University of Traditional Chinese Medicine has passed the identification and limitation of malignant loads and high-power electrical appliances. campus and ensure the stable and reliable operation of campus safety and electrical systems.
Comprehensive data management to provide basis for scientific decision-making
Comprehensive data-based management and modern technology that "leave traces after swallowing" provide the most complete "big data" for campus management and provide a basis for scientific decision-making.
3. Intelligent control
Smart meter box realizes distributed control of electricity consumption in student dormitories
Through the use of Sanchuan smart meter box, it has the function of automatically collecting RS485 serial port data and saving it, and then uploading it to the network server, in addition to the functions of network time calibration, GPS positioning, and GPS time calibration. The dormitory is currently divided into four circuits, which realizes the effect of students' distributed control of the four circuits on the mobile terminal APP.
Data is uploaded to the cloud for real-time measurement and control
The data is uploaded to the cloud, and real-time measurement and control of electricity consumption data can be realized through the Sanchuan Zhishe APP.
4. Fire safety
Through the intelligent load controller integrating measurement + protection + control + communication, each load is managed finely, which greatly improves the reliability, safety and abnormal protection characteristics of the campus power distribution system. At the same time, it also improves the safety level of campus electricity consumption, eliminates the potential safety hazards caused by the use of malignant loads by students, and avoids the management contradictions caused by frequent dormitory safety inspections, and enhances students' sense of participation and gain. Real-time monitoring of malignant loads, abnormal power consumption, real-time alarm and removal within 20ms, comprehensive elimination of fire hazards and improved safety.
